Android 6.0 permissions multiples

voici un exemple détaillé avec plusieurs demandes de permission:-

l'application a besoin de 2 permissions au démarrage . SEND_SMS et ACCESS_FINE_LOCATION (tous deux sont mentionnés dans le manifeste.XML.)

j'utilise Support Library v4 qui est prêt à gérer Android pre-Marshmallow et donc pas besoin de vérifier les versions de construction.

dès Que l'application démarre, il vous demande de plusieurs les autorisations d'ensemble. Si les deux permissions sont accordées, le flux normal disparaît.

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 () font partie de la bibliothèque de soutien.

Si une ou plusieurs permissions ne sont pas accordées, ActivityCompat.requestPermissions() demandera les permissions et le contrôle va à la méthode de callback onRequestPermissionsResult ().

vous devez vérifier la valeur du drapeau shouldShowRequestPermissionRationale() dans la méthode de callback onRequestPermissionsResult ().

il n'y a que deux cas:--

Cas 1: -chaque fois que l'utilisateur clique sur Refuser les autorisations (y compris la première fois), elle retournera true. Ainsi, lorsque l'utilisateur nie, nous pouvons montrer plus d'explications et demander à nouveau

cas 2: - seulement si l'utilisateur sélectionne" ne demande plus jamais " il retournera false. Dans ce cas, nous pouvons continuer avec des fonctionnalités limitées et guide de l'utilisateur pour activer les autorisations de paramètres pour plus de fonctionnalités, ou nous pouvons terminer l'installation, si les autorisations sont triviales pour l'application.

C'est facile, le faire de cette façon

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

Dans votre 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(),

mon approche est basée sur la réponse de Nicks et je l'espère est un peu plus utilisable pour les permissions multiples (autant que nécessaire, pas seulement deux). Il suggère d'ajouter des Permissionsuniquesresponsabilité par classe:

import android.app.Activity;

public class PermissionsHelper {

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();
                }
            }
        }
    }
}

}

si une ou plusieurs permissions requises n'ont pas été accordées par l'utilisateur, le message AlertDialog détaillé lui sera montré.

exemple d'utilisation en activité:

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);
}

espère que cela sera utile pour quelqu'un.

vous pouvez simplement copier et coller ce code, il fonctionne très bien. changement de contexte(ce) et des autorisations selon vous.

j'ai implémenté avec succès le code simple pour la permission Multiple à la fois. Suivez les étapes ci-dessous 1:L'Utilitaire Make.classe java comme ci-dessous

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: maintenant appelez

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

dans votre Activité onCreate (), ou selon votre logique.

3:Vérifiez maintenant l'autorisation avant d'effectuer l'opération pour la tâche particulière

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

4: Maintenant implémenter la méthode onRequestPermissionsResult() dans votre activité comme ci-dessous

  @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;
    }
}

après avoir vu toutes les réponses longues et complexes. Je veux poster cette réponse.

rxpermission est largement utilisé bibliothèque maintenant pour demander la permission dans un code de ligne.

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
    }
});

ajouter à votre build.gradle

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

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

N'est-ce pas facile?

        /*If We accept permission*/
    } else if (grantResults[0] == PackageManager.PERMISSION_DENIED) {

    }
}

j'ai trouvé ceci est dans L'exemple de permissions d'exécution de Google github.

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

cochez la rubrique "demander plusieurs permissions à la fois" dans cet article:

choses que vous devez savoir à propos de Android M permissions

C'est très bien expliqué, et peut également toucher d'autres sujets connexes que vous n'avez pas idée.

Court et doux :). ce en quoi je crois.

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;

utilisez helper comme ceci (les noms de permissions n'ont pas d'importance).

                return false;
            }
        }
    }
    return true;
}

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

private static boolean isNewPermissionModel() {
    return VERSION.SDK_INT > VERSION_CODES.LOLLIPOP_MR1;

Simple façon de poser plusieurs permission,

https://github.com/sachinvarma/EasyPermission

comment ajouter :

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

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

Comment demander la permission:

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

 new EasyPermissionInit(MainActivity.this, permission);

ça pourrait aider quelqu'un à l'avenir.

j'utilise juste un tableau pour réaliser plusieurs requêtes, j'espère qu'il aidera quelqu'un. (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
        if (ActivityCompat.checkSelfPermission(mContext, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED
                && ActivityCompat.checkSelfPermission(mContext, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
            mIndex ++
            requestList[mIndex] = Manifest.permission.ACCESS_FINE_LOCATION
        }

        if(mIndex != -1){
            ActivityCompat.requestPermissions(this, requestList, PERMISSIONS_REQUEST_ALL)
        }
    }


    // permission response
    override fun onRequestPermissionsResult(requestCode: Int,
                                            permissions: Array<String>, grantResults: IntArray) {
        when (requestCode) {
            PERMISSIONS_REQUEST_ALL -> {
                // If request is cancelled, the result arrays are empty.
                if (grantResults.isNotEmpty() && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                    // permission accept location
                    if (ContextCompat.checkSelfPermission(this,
                                    Manifest.permission.CALL_PHONE) == PackageManager.PERMISSION_GRANTED) {
                        Log.d(TAG, "Phone Call permission accept.")
                    }

                    // permission accept location
                    if (ContextCompat.checkSelfPermission(this,
                                    Manifest.permission.SEND_SMS) == PackageManager.PERMISSION_GRANTED) {
                        Log.d(TAG, "SMS permission accept.")
                    }

                    // permission accept location
                    if (ContextCompat.checkSelfPermission(this,
                                    Manifest.permission.READ_EXTERNAL_STORAGE) == PackageManager.PERMISSION_GRANTED) {
                        Log.d(TAG, "SMS permission accept.")
                    }

                    // permission accept location
                    if (ContextCompat.checkSelfPermission(this,
                                    Manifest.permission.ACCESS_FINE_LOCATION) == PackageManager.PERMISSION_GRANTED) {
                        Log.d(TAG, "Location permission accept.")
                    }

                } else {
                    Toast.makeText(mContext, "Permission Failed!", Toast.LENGTH_LONG).show()
                }
                return
            }
        }
    }

il n'y a rien de mal à ce que les réponses demandent des permissions multiples, mais le code de résultat de permission multiple n'est pas implémenté de manière très élégante et peut causer une mauvaise vérification du résultat de permission.

if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) est une terrible logique pour vérifier le résultat de plusieurs permissions, Je ne sais pas pourquoi Google a mis en œuvre un code si terrible.

c'est un gâchis surtout quand vous vérifiez plusieurs permissions. Disons que vous demandez CAMERA , ACCESS_FINE_LOCATION et ACCESS_NETWORK_STATE .

vous devez vérifier pour ACCESS_FINE_LOCATION mais l'utilisateur seulement accordé CAMERA à la première course et vous vérifiez pour grantResults[1] mais dans la deuxième course ACCESS_FINE_LOCATION devient la permission avec l'index 0. J'ai eu tellement de problèmes avec l'utilisateur n'accordant pas toutes les permissions à la fois et doivent écrire si inutile logique de résultat de permission.

vous devez utiliser

   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;
        }
    }

ou plus simple

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

dans la méthode onPermissionRequestResult .
