Android 6.0 mehrere Berechtigungen

Ich weiß, dass Android 6.0 neue Berechtigungen hat, und ich weiß, dass ich sie mit so etwas aufrufen kann 

if (ContextCompat.checkSelfPermission(this, Manifest.permission.WRITE_EXTERNAL_STORAGE) !=
    PackageManager.PERMISSION_GRANTED) {
    ActivityCompat.requestPermissions(this,
        new String[] { 
            Manifest.permission.WRITE_EXTERNAL_STORAGE
        }, PERMISSION_WRITE_STORAGE);
}

Heute habe ich eine Google-App gesehen, die 3 Berechtigungen benötigt: Kontakte, SMS und Kamera. Es wird eine Seite 1-3 erstellt und alle gleichzeitig zur Aktivierung aufgerufen.

Kann mir jemand sagen, wie ich 4 Berechtigungen aufrufen kann, um sie gleichzeitig wie SMS, Kamera, Kontakte und Speicher zu aktivieren?

Beispiel (Name der Google-App vergessen :()
.__ Die App benötigt SMS, Kontakte und Kamera 

die App fragte mich (und machte einen Dialog Seite 1-3), SMS aktivieren, Kontakte aktivieren und dann Kamera. Diese Google-App rief also alle drei erforderlichen Berechtigungen zusammen und meine Frage ist, wie ich das gleiche erreichen kann.

Fügen Sie einfach alle 4 Berechtigungen in den Aufruf ActivityCompat.requestPermissions(...) ein, und Android ruft sie automatisch wie von Ihnen erwähnt auf.

Ich habe eine Hilfsmethode, um mehrere Berechtigungen zu überprüfen und festzustellen, ob eine davon nicht gewährt wird.

public static boolean hasPermissions(Context context, String... permissions) {
    if (context != null && permissions != null) {
        for (String permission : permissions) {
            if (ActivityCompat.checkSelfPermission(context, permission) != PackageManager.PERMISSION_GRANTED) {
                return false;
            }
        }
    }
    return true;
}

Dann senden Sie ihm einfach alle Berechtigungen. Android fragt nur nach denen, die es benötigt.

// The request code used in ActivityCompat.requestPermissions()
// and returned in the Activity's onRequestPermissionsResult()
int PERMISSION_ALL = 1; 
String[] PERMISSIONS = {
  Android.Manifest.permission.READ_CONTACTS, 
  Android.Manifest.permission.WRITE_CONTACTS, 
  Android.Manifest.permission.WRITE_EXTERNAL_STORAGE, 
  Android.Manifest.permission.READ_SMS, 
  Android.Manifest.permission.CAMERA
};

if(!hasPermissions(this, PERMISSIONS)){
    ActivityCompat.requestPermissions(this, PERMISSIONS, PERMISSION_ALL);
}

Hier ist ein detailliertes Beispiel mit mehreren Berechtigungsanfragen: -

Die App benötigt beim Start 2 Berechtigungen. SEND_SMS und ACCESS_FINE_LOCATION (beide werden in manifest.xml erwähnt).

Ich verwende Support Library v4, das für die Verwendung von Android vor Marshmallow vorbereitet ist und keine Build-Versionen prüfen muss.

Sobald die App gestartet wird, werden mehrere Berechtigungen gleichzeitig benötigt. Wenn beide Berechtigungen erteilt werden, wird der normale Fluss ausgeführt.

 enter image description here

public static final int REQUEST_ID_MULTIPLE_PERMISSIONS = 1;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    if(checkAndRequestPermissions()) {
        // carry on the normal flow, as the case of  permissions  granted.
    }
}

private  boolean checkAndRequestPermissions() {
    int permissionSendMessage = ContextCompat.checkSelfPermission(this,
            Manifest.permission.SEND_SMS);
    int locationPermission = ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION);
    List<String> listPermissionsNeeded = new ArrayList<>();
    if (locationPermission != PackageManager.PERMISSION_GRANTED) {
        listPermissionsNeeded.add(Manifest.permission.ACCESS_FINE_LOCATION);
    }
    if (permissionSendMessage != PackageManager.PERMISSION_GRANTED) {
        listPermissionsNeeded.add(Manifest.permission.SEND_SMS);
    }
    if (!listPermissionsNeeded.isEmpty()) {
        ActivityCompat.requestPermissions(this, listPermissionsNeeded.toArray(new String[listPermissionsNeeded.size()]),REQUEST_ID_MULTIPLE_PERMISSIONS);
        return false;
    }
    return true;
}

ContextCompat.checkSelfPermission (), ActivityCompat.requestPermissions (), ActivityCompat.shouldShowRequestPermissionRationale () sind Teil der Support-Bibliothek.

Wenn eine oder mehrere Berechtigungen nicht erteilt werden, fordert ActivityCompat.requestPermissions () Berechtigungen an, und das Steuerelement wechselt zur Callback-Methode onRequestPermissionsResult ().

Sie sollten den Wert von shouldShowRequestPermissionRationale () in der Callback-Methode onRequestPermissionsResult () überprüfen. 

Es gibt nur zwei Fälle: -

Fall 1: - Wenn der Benutzer zu einem beliebigen Zeitpunkt auf Ablehnungsberechtigungen (einschließlich des allerersten Mal) klickt, wird true zurückgegeben. Wenn der Benutzer dies ablehnt, können wir weitere Erklärungen anzeigen und erneut fragen

Fall 2: - Nur wenn der Benutzer "nie wieder gefragt" auswählt, wird "false" zurückgegeben. In diesem Fall können wir mit eingeschränkten Funktionen fortfahren und den Benutzer anweisen, die Berechtigungen aus den Einstellungen für weitere Funktionen zu aktivieren, oder wir können das Setup beenden, wenn die Berechtigungen für die App trivial sind.

Es ist einfach, mach es so

private static final int REQUEST_READ_PHONE_STATE = 110 , REQUEST_ACCESS_FINE_LOCATION = 111, REQUEST_WRITE_STORAGE = 112;

In Ihrem onCreate

 //request permission
    boolean hasPermissionPhoneState = (ContextCompat.checkSelfPermission(getApplicationContext(),
            Manifest.permission.READ_PHONE_STATE) == PackageManager.PERMISSION_GRANTED);
    if (!hasPermissionPhoneState) {
        ActivityCompat.requestPermissions(LoginActivity.this,
                new String[]{Manifest.permission.READ_PHONE_STATE},
                REQUEST_READ_PHONE_STATE);
    }

    boolean hasPermissionLocation = (ContextCompat.checkSelfPermission(getApplicationContext(),
            Manifest.permission.ACCESS_FINE_LOCATION) == PackageManager.PERMISSION_GRANTED);
    if (!hasPermissionLocation) {
        ActivityCompat.requestPermissions(LoginActivity.this,
                new String[]{Manifest.permission.ACCESS_FINE_LOCATION},
                REQUEST_ACCESS_FINE_LOCATION);
    }

    boolean hasPermissionWrite = (ContextCompat.checkSelfPermission(getApplicationContext(),
            Manifest.permission.WRITE_EXTERNAL_STORAGE) == PackageManager.PERMISSION_GRANTED);
    if (!hasPermissionWrite) {
        ActivityCompat.requestPermissions(LoginActivity.this,
                new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE},
                REQUEST_WRITE_STORAGE);
    }

Dann überprüfen Sie das Ergebnis

@Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
    super.onRequestPermissionsResult(requestCode, permissions, grantResults);
    switch (requestCode)
    {

            if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED)
            {
                Toast.makeText(LoginActivity.this, "Permission granted.", Toast.LENGTH_SHORT).show();
                //reload my activity with permission granted or use the features what required the permission
                finish();
                startActivity(getIntent());
            } else
            {
                Toast.makeText(LoginActivity.this, "The app was not allowed to get your phone state. Hence, it cannot function properly. Please consider granting it this permission", Toast.LENGTH_LONG).show();
            }
        }
        case REQUEST_ACCESS_FINE_LOCATION: {
            if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED)
            {
                Toast.makeText(LoginActivity.this, "Permission granted.", Toast.LENGTH_SHORT).show();
                //reload my activity with permission granted or use the features what required the permission
                finish();
                startActivity(getIntent());
            } else
            {
                Toast.makeText(LoginActivity.this, "The app was not allowed to get your location. Hence, it cannot function properly. Please consider granting it this permission", Toast.LENGTH_LONG).show();
            }
        }

        case REQUEST_WRITE_STORAGE: {
            if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED)
            {
                Toast.makeText(LoginActivity.this, "Permission granted.", Toast.LENGTH_SHORT).show();
                //reload my activity with permission granted or use the features what required the permission
                finish();
                startActivity(getIntent());
            } else
            {
                Toast.makeText(LoginActivity.this, "The app was not allowed to write to your storage. Hence, it cannot function properly. Please consider granting it this permission", Toast.LENGTH_LONG).show();
            }
        }
    }

Die folgende Methodik ist ungefähr 

  • berechtigungen dynamisch anfordern;
  • ein AlertDialog wird angezeigt, wenn der Benutzer Berechtigungen verweigert
  • schleife, bis der Benutzer die Berechtigungen akzeptiert

Eine "statische" Klasse für Berechtigungsmethoden erstellen

public class PermissionsUtil {
    public static final int PERMISSION_ALL = 1;

    public static boolean doesAppNeedPermissions(){
        return Android.os.Build.VERSION.SDK_INT > Build.VERSION_CODES.Lollipop_MR1;
    }

    public static String[] getPermissions(Context context)
            throws PackageManager.NameNotFoundException {
        PackageInfo info = context.getPackageManager().getPackageInfo(
                context.getPackageName(), PackageManager.GET_PERMISSIONS);

        return info.requestedPermissions;
    }

    public static void askPermissions(Activity activity){
        if(doesAppNeedPermissions()) {
            try {
                String[] permissions = getPermissions(activity);

                if(!checkPermissions(activity, permissions)){
                    ActivityCompat.requestPermissions(activity, permissions,
                            PERMISSION_ALL);
                }
            } catch(Exception e) {
                e.printStackTrace();
            }
        }
    }

    public static boolean checkPermissions(Context context, String... permissions){
        if (Android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.M && context != null &&
                permissions != null) {
            for (String permission : permissions) {
                if (ContextCompat.checkSelfPermission(context, permission) !=
                        PackageManager.PERMISSION_GRANTED) {
                    return false;
                }
            }
        }
        return true;
    }
}

In MainActivity.Java

    private void checkPermissions(){
        PermissionsUtil.askPermissions(this);
    }

    @Override
    public void onRequestPermissionsResult(int requestCode,
                                           @NonNull String[] permissions,
                                           @NonNull int[] grantResults) {
        super.onRequestPermissionsResult(requestCode, permissions, grantResults);
        switch (requestCode) {
            case PermissionsUtil.PERMISSION_ALL: {

                if (grantResults.length > 0) {

                    List<Integer> indexesOfPermissionsNeededToShow = new ArrayList<>();

                    for(int i = 0; i < permissions.length; ++i) {
                        if(ActivityCompat.shouldShowRequestPermissionRationale(this, permissions[i])) {
                            indexesOfPermissionsNeededToShow.add(i);
                        }
                    }

                    int size = indexesOfPermissionsNeededToShow.size();
                    if(size != 0) {
                        int i = 0;
                        boolean isPermissionGranted = true;

                        while(i < size && isPermissionGranted) {
                            isPermissionGranted = grantResults[indexesOfPermissionsNeededToShow.get(i)]
                                    == PackageManager.PERMISSION_GRANTED;
                            i++;
                        }

                        if(!isPermissionGranted) {

                            showDialogNotCancelable("Permissions mandatory",
                                    "All the permissions are required for this app",
                                    new DialogInterface.OnClickListener() {
                                        @Override
                                        public void onClick(DialogInterface dialogInterface, int i) {
                                            checkPermissions();
                                        }
                                    });
                        }
                    }
                }
            }
        }
    }

    private void showDialogNotCancelable(String title, String message,
                                         DialogInterface.OnClickListener okListener) {
        new AlertDialog.Builder(this)
                .setTitle(title)
                .setMessage(message)
                .setPositiveButton("OK", okListener)
                .setCancelable(false)
                .create()
                .show();
    }

Mein Ansatz basiert auf der Antwort von Nicks und ist hoffentlich etwas benutzerfreundlicher für mehrere (so viele wie nötig, nicht nur zwei) Berechtigungen .. _ Sie schlägt vor, die PermissionHelper-Klasse mit der einzigen Verantwortung hinzuzufügen:

import Android.app.Activity;
import Android.app.AlertDialog;
import Android.content.pm.PackageManager;
import Android.support.v4.app.ActivityCompat;
import Android.support.v4.content.ContextCompat;
import Android.util.Log;

import Java.util.ArrayList;
import Java.util.HashMap;
import Java.util.List;
import Java.util.Map;

public class PermissionsHelper {

private static final int REQUEST_ID_MULTIPLE_PERMISSIONS = 100; // any code you want.

public void checkAndRequestPermissions(Activity activity, String... permissions) {
    List<String> listPermissionsNeeded = new ArrayList<>();
    for (String permission : permissions) {
        if (ContextCompat.checkSelfPermission(activity, permission) != PackageManager.PERMISSION_GRANTED) {
            listPermissionsNeeded.add(permission);
        }
    }
    if (!listPermissionsNeeded.isEmpty()) {
        ActivityCompat.requestPermissions(activity, listPermissionsNeeded.toArray(new String[listPermissionsNeeded.size()]), REQUEST_ID_MULTIPLE_PERMISSIONS);
    }
}

public void onRequestPermissionsResult(Activity activity, int requestCode, String permissions[], int[] grantResults) {
    switch (requestCode) {
        case REQUEST_ID_MULTIPLE_PERMISSIONS: {
            Map<String, Integer> perms = new HashMap<>();

            for (String permission : permissions) {
                perms.put(permission, PackageManager.PERMISSION_GRANTED);
            }

            if (grantResults.length > 0) {
                for (int i = 0; i < permissions.length; i++)
                    perms.put(permissions[i], grantResults[i]);

                boolean allPermissionsGranted = true;
                for (String permission1 : permissions) {
                    allPermissionsGranted = allPermissionsGranted && (perms.get(permission1) == PackageManager.PERMISSION_GRANTED);
                }

                if (allPermissionsGranted) {
                    Log.d(PermissionsHelper.class.getSimpleName(), "onRequestPermissionsResult: all permissions granted");
                } else {
                    for (String permission2 : perms.keySet())
                        if (perms.get(permission2) == PackageManager.PERMISSION_GRANTED)
                            perms.remove(permission2);

                    StringBuilder message = new StringBuilder("The app has not been granted permissions:\n\n");
                    for (String permission : perms.keySet()) {
                        message.append(permission);
                        message.append("\n");
                    }
                    message.append("\nHence, it cannot function properly." +
                            "\nPlease consider granting it this permission in phone Settings.");

                    AlertDialog.Builder builder = new AlertDialog.Builder(activity);
                    builder.setTitle(R.string.permission_required)
                            .setMessage(message)
                            .setPositiveButton(Android.R.string.ok, (dialog, id) -> dialog.cancel());
                    AlertDialog alert = builder.create();
                    alert.show();
                }
            }
        }
    }
}

}

Wenn eine oder mehrere erforderliche Berechtigungen vom Benutzer nicht erteilt wurden, wird ihm die detaillierte AlertDialog-Meldung angezeigt.

Anwendungsbeispiel in Activity:

private PermissionsHelper permissionsHelper;

@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    checkPermissions();

    //any other code
}

@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
    permissionsHelper.onRequestPermissionsResult(this, requestCode, permissions, grantResults);
}

private void checkPermissions() {
    permissionsHelper = new PermissionsHelper();
    permissionsHelper.checkAndRequestPermissions(this,
            Manifest.permission.READ_EXTERNAL_STORAGE,
            Manifest.permission.ACCESS_FINE_LOCATION,
            Manifest.permission.ACCESS_COARSE_LOCATION);
}

Ich hoffe, dass dies für jemanden nützlich sein wird.

Überprüfung jeder Situation

wenn verweigert - Zeigt dem Benutzer den Alert-Dialog an, warum wir eine Berechtigung benötigen

        // if camera request is denied
        if (ActivityCompat.shouldShowRequestPermissionRationale(this,

            AlertDialog.Builder builder = new AlertDialog.Builder(this);
            builder.setMessage("You need to give permission to take pictures in order to work this feature.");
            builder.setNegativeButton("CANCEL", new DialogInterface.OnClickListener() {

            });
            builder.show();

        } 

    }
}

Berechtigungsergebnisse prüfen

 @Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
    super.onRequestPermissionsResult(requestCode, permissions, grantResults);

    switch (requestCode) {
        case CAMERA_PERMISSION_REQUEST_CODE:
            if (grantResults.length > 0 && permissions[0].equals(Manifest.permission.CAMERA)) {
                // check whether camera permission granted or not.
                if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                    launchCamera();
                }
            }
            break;
        case STORAGE_PERMISSION_REQUEST_CODE:
            if (grantResults.length > 0 && permissions[0].equals(Manifest.permission.WRITE_EXTERNAL_STORAGE)) {
                // check whether storage permission granted or not.
                if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                    launchCamera();
                }
            }
            break;
        case MULTIPLE_PERMISSIONS:
            if (grantResults.length > 0 && permissions[0].equals(Manifest.permission.CAMERA) && permissions[1].equals(Manifest.permission.WRITE_EXTERNAL_STORAGE)) {
                // check whether All permission granted or not.
                if (grantResults[0] == PackageManager.PERMISSION_GRANTED && grantResults[1] == PackageManager.PERMISSION_GRANTED) {
                    launchCamera();

                }
            }
            break;
        default:
            break;
    }
}

sie können diesen Code einfach kopieren und einfügen, er funktioniert einwandfrei. Ändern Sie den Kontext (dies) und die Berechtigungen nach Ihren Wünschen.

Kurz und bündig :). woran ich glaube.

int PERMISSION_ALL = 1;
String[] PERMISSIONS = {Manifest.permission.CAMERA, Manifest.permission.WRITE_EXTERNAL_STORAGE}; // List of permissions required

public void askPermission()
{
    for (String permission : PERMISSIONS) {
        if (ActivityCompat.checkSelfPermission(this, permission) != PackageManager.PERMISSION_GRANTED) {
            requestPermissions(PERMISSIONS, PERMISSION_ALL);
            return;
        }
    }
}

@Override
public void onRequestPermissionsResult(int requestCode, String[] permissions,
                                       int[] grantResults) {

    switch (requestCode) {
        case 1:{
            if(grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED && grantResults[1] == PackageManager.PERMISSION_GRANTED){
                //Do your work.
            } else {
                Toast.makeText(this, "Until you grant the permission, we cannot proceed further", Toast.LENGTH_SHORT).show();
            }
            return;
        }
    }

Nachdem ich all die langen und komplexen Antworten gesehen habe. Ich möchte diese Antwort posten.

RxPermission ist eine weit verbreitete Bibliothek, in der die Erlaubnis in einem Zeilencode angefordert wird.

RxPermissions rxPermissions = new RxPermissions(this);
rxPermissions
.request(Manifest.permission.CAMERA,
         Manifest.permission.READ_PHONE_STATE)
.subscribe(granted -> {
    if (granted) {
       // All requested permissions are granted
    } else {
       // At least one permission is denied
    }
});

füge in deinem build.gradle hinzu

allprojects {
    repositories {
        ...
        maven { url 'https://jitpack.io' }
    }
}

dependencies {
    implementation 'com.github.tbruyelle:rxpermissions:0.10.1'
    implementation 'com.jakewharton.rxbinding2:rxbinding:2.1.1'
}

Ist das nicht einfach?

Es ist nichts falsch mit Antworten, die nach mehreren Berechtigungen fragen, aber der Code für mehrere Berechtigungsergebnisse ist nicht sehr elegant implementiert und kann dazu führen, dass falsche Berechtigungsergebnisse geprüft werden.

if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) ist eine schreckliche Logik zum Überprüfen mehrerer Berechtigungsergebnisse. Ich weiß nicht, warum Google einen so schrecklichen Code implementiert hat.

Dies ist insbesondere dann ein Chaos, wenn Sie mehrere Berechtigungen überprüfen. Angenommen, Sie fragen nach CAMERA, ACCESS_FINE_LOCATION und ACCESS_NETWORK_STATE.

Sie müssen nach ACCESS_FINE_LOCATION suchen, aber der Benutzer hat nur CAMERA beim ersten Durchlauf gewährt, und Sie prüfen nach grantResults[1]. Im zweiten Durchlauf wird ACCESS_FINE_LOCATION die Berechtigung mit Index 0. Ich habe so viele Probleme mit dem Benutzer, der nicht alle Berechtigungen auf einmal erteilt, und muss so sinnlos schreiben Berechtigungsergebnislogik.

Sie sollten entweder verwenden

   int size = permissions.length;
    boolean locationPermissionGranted = false;

    for (int i = 0; i < size; i++) {
        if (permissions[i].equals(Manifest.permission.ACCESS_FINE_LOCATION)
                && grantResults[i] == PackageManager.PERMISSION_GRANTED) {
            locationPermissionGranted = true;
        }
    }

Oder einfachere

   if (ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION)
                == PackageManager.PERMISSION_GRANTED) {
           // Do something ...
        }

in onPermissionRequestResult Methode.

Ich habe erfolgreich einfachen Code für die Mehrfachberechtigung um Once.__ implementiert. Befolgen Sie die folgenden Schritte

public class Utility {
public static final int MY_PERMISSIONS_REQUEST = 123;
@TargetApi(Build.VERSION_CODES.JELLY_BEAN)
public static boolean checkPermissions(Context context, String... permissions) {
    if (Android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.M && context != null && permissions != null) {
        for (String permission : permissions) {
            if (ActivityCompat.checkSelfPermission(context, permission) != PackageManager.PERMISSION_GRANTED) {
                if (ActivityCompat.shouldShowRequestPermissionRationale((Activity) context, permission)) {
                    ActivityCompat.requestPermissions((Activity) context, new String[]{Manifest.permission.READ_EXTERNAL_STORAGE,Manifest.permission.CALL_PHONE,Manifest.permission.GET_ACCOUNTS}, MY_PERMISSIONS_REQUEST);
                } else {
                    ActivityCompat.requestPermissions((Activity) context, new String[]{Manifest.permission.READ_EXTERNAL_STORAGE,Manifest.permission.CALL_PHONE,Manifest.permission.GET_ACCOUNTS}, MY_PERMISSIONS_REQUEST);
                }
                return false;
            }
        }
    }
    return true;
}
}

2: Jetzt anrufen 

boolean permissionCheck = Utility.checkPermissions(this, Manifest.permission.READ_EXTERNAL_STORAGE, Manifest.permission.CALL_PHONE, Manifest.permission.GET_ACCOUNTS);  

in Ihrer Activity onCreate () oder nach Ihrer Logik.

3: Überprüfen Sie nun die Berechtigung, bevor Sie den Vorgang für eine bestimmte Aufgabe ausführen

if (permissionCheck) {
 performTaskOperation();//this method what you need to perform
} else {
        Toast.makeText(this, "Need permission ON.", Toast.LENGTH_SHORT).show();
       }

4: Implementieren Sie nun die onRequestPermissionsResult () - Methode in Ihrer Activity wie folgt

  @Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
    switch (requestCode) {
        case Utility.MY_PERMISSIONS_REQUEST:
            if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                if (userChoosenTask.equals("STORAGE"))
                    performTaskOperation();//this method what you need to perform
            }
            break;
    }
}

Einfache Möglichkeit, mehrere Berechtigungen anzufordern,

https://github.com/sachinvarma/EasyPermission

Wie man hinzufügen :

repositories {
        maven { url "https://jitpack.io" }
    }

implementation 'com.github.sachinvarma:EasyPermission:1.0.1'

Wie man um Erlaubnis fragt:

 List<String> permission = new ArrayList<>();
 permission.add(EasyPermissionList.READ_EXTERNAL_STORAGE);
 permission.add(EasyPermissionList.ACCESS_FINE_LOCATION);

 new EasyPermissionInit(MainActivity.this, permission);

Für mehr Details ->

https://github.com/sachinvarma/EasyPermission/blob/master/app/src/main/Java/com/sachinvarma/easypermissionsample/MainActivity.Java

Es kann in Zukunft jemandem helfen.

Ich habe festgestellt, dass dies in den Laufzeitberechtigungsbeispielen von Googles Github ist.

 private static String[] PERMISSIONS_CONTACT = {Manifest.permission.READ_CONTACTS,
        Manifest.permission.WRITE_CONTACTS};
private static final int REQUEST_CONTACTS = 1;
ActivityCompat.requestPermissions(this, PERMISSIONS_CONTACT, REQUEST_CONTACTS);

Verwenden Sie diesen Helfer (Berechtigungsnamen spielen keine Rolle).

                return false;
            }
        }
    }
    return true;
}

private static boolean shouldShowRationale(Activity activity, String permission) {
    return isNewPermissionModel() && ActivityCompat.shouldShowRequestPermissionRationale(activity, permission);

Das habe ich in meiner Tätigkeit getan. Hoffen wird hilfreich sein. Ich bitte um Kamera- und Mikrofonberechtigungen.

public class ActiveCallActivity extends AppCompatActivity {

Ich verwende einfach ein Array, um mehrere Anfragen zu erfüllen. Ich hoffe, es hilft jemandem. (Kotlin)

    // got all permission
    private fun requestPermission(){
        var mIndex: Int = -1
        var requestList: Array<String> = Array(10, { "" } )

        // phone call Permission
        if (ContextCompat.checkSelfPermission(this, Manifest.permission.CALL_PHONE) != PackageManager.PERMISSION_GRANTED) {
            mIndex ++
            requestList[mIndex] = Manifest.permission.CALL_PHONE
        }
        // SMS Permission
        if (ContextCompat.checkSelfPermission(this, Manifest.permission.READ_CONTACTS) != PackageManager.PERMISSION_GRANTED) {
            mIndex ++
            requestList[mIndex] = Manifest.permission.SEND_SMS
        }

        // Access photos Permission
        if (ActivityCompat.checkSelfPermission(this, Manifest.permission.READ_EXTERNAL_STORAGE) != PackageManager.PERMISSION_GRANTED) {
            mIndex ++
            requestList[mIndex] = Manifest.permission.READ_EXTERNAL_STORAGE
        }

        // Location Permission

Überprüfen Sie den Abschnitt "Mehrere Berechtigungen gleichzeitig anfordern" in diesem Artikel:

Dinge, die Sie über Android M-Berechtigungen wissen müssen

Es ist sehr gut erklärt und kann auch andere verwandte Themen betreffen, über die Sie nicht nachdenken.

Sie können Dexter verwenden

In build.gradle hinzufügen:

implementation 'com.karumi:dexter:5.0.0'

Und verwenden Sie es in Ihrer Tätigkeit als:

val requiredPermissions = when {
            Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q -> listOf(Manifest.permission.ACCESS_FINE_LOCATION,
                Manifest.permission.ACCESS_COARSE_LOCATION,
                Manifest.permission.ACCESS_BACKGROUND_LOCATION)
            else -> listOf(Manifest.permission.ACCESS_FINE_LOCATION,
                Manifest.permission.ACCESS_COARSE_LOCATION)
        }

Dexter.withActivity(this)
     .withPermissions(
           requiredPermissions
      )
     .withListener(object : MultiplePermissionsListener {
        override fun onPermissionRationaleShouldBeShown(
             permissions: MutableList<PermissionRequest>?,
                    token: PermissionToken?
             ) {
                    /* ... */
                }


        override fun onPermissionsChecked(report: MultiplePermissionsReport) = 
             if (report.isAnyPermissionPermanentlyDenied) {
                toast("You should grant all permissions") 
             } else {
                toast("All permissions granted")

                // continue here if permission is a must

              }).check()

             // continue here if permission is not a must
