Comment vérifier les autorisations accordées au moment de l'exécution?

Dans Android M (Aperçu) l'utilisateur peut choisir une application spécifique et récupérer une autorisation spécifique.

Je demande donc Comment vérifier les autorisations accordées au moment de l'exécution?

Agréable !!

Je viens de trouver mon besoin, nous pouvons vérifier si l'autorisation est accordée par:

checkSelfPermission(Manifest.permission.READ_CONTACTS)

Demander des autorisations si nécessaire

if (checkSelfPermission(Manifest.permission.READ_CONTACTS)
            != PackageManager.PERMISSION_GRANTED) {
        requestPermissions(new String[]{Manifest.permission.READ_CONTACTS},
                MY_PERMISSIONS_REQUEST_READ_CONTACTS);

        // MY_PERMISSIONS_REQUEST_READ_CONTACTS is an
        // app-defined int constant

        return;
    }

Gérer la réponse à la demande d'autorisation

@Override
public void onRequestPermissionsResult(int requestCode,
        String permissions[], int[] grantResults) {
    switch (requestCode) {
        case MY_PERMISSIONS_REQUEST_READ_CONTACTS: {
            if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {

                // permission was granted, yay! do the
                // calendar task you need to do.

            } else {

                // permission denied, boo! Disable the
                // functionality that depends on this permission.
            }
            return;
        }

        // other 'switch' lines to check for other
        // permissions this app might request
    }
}

Essayez plutôt ce code de requête simple
https://www.learn2crack.com/2015/10/Android-Marshmallow-permissions.html

public static final int REQUEST_ID_MULTIPLE_PERMISSIONS = 1;

private  boolean checkAndRequestPermissions() {
    int camera = ContextCompat.checkSelfPermission(this, Android.Manifest.permission.CAMERA);
    int storage = ContextCompat.checkSelfPermission(this, Android.Manifest.permission.WRITE_EXTERNAL_STORAGE);
    int loc = ContextCompat.checkSelfPermission(this, Android.Manifest.permission.ACCESS_COARSE_LOCATION);
    int loc2 = ContextCompat.checkSelfPermission(this, Android.Manifest.permission.ACCESS_FINE_LOCATION);
    List<String> listPermissionsNeeded = new ArrayList<>();

    if (camera != PackageManager.PERMISSION_GRANTED) {
        listPermissionsNeeded.add(Android.Manifest.permission.CAMERA);
    }
    if (storage != PackageManager.PERMISSION_GRANTED) {
        listPermissionsNeeded.add(Android.Manifest.permission.WRITE_EXTERNAL_STORAGE);
    }
    if (loc2 != PackageManager.PERMISSION_GRANTED) {
        listPermissionsNeeded.add(Android.Manifest.permission.ACCESS_FINE_LOCATION);
    }
    if (loc != PackageManager.PERMISSION_GRANTED) {
        listPermissionsNeeded.add(Android.Manifest.permission.ACCESS_COARSE_LOCATION);
    }
    if (!listPermissionsNeeded.isEmpty())
    {
        ActivityCompat.requestPermissions(this,listPermissionsNeeded.toArray
                (new String[listPermissionsNeeded.size()]),REQUEST_ID_MULTIPLE_PERMISSIONS);
        return false;
    }
    return true;
}

Essayez ceci pour vérifier la permission d'exécution: 

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    checkRunTimePermission();
}

Vérifier l'autorisation d'exécution:

private void checkRunTimePermission() {
    String[] permissionArrays = new String[]{Manifest.permission.CAMERA, Manifest.permission.WRITE_EXTERNAL_STORAGE};

    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
        requestPermissions(permissionArrays, 11111);
    } else {
         // if already permition granted
        // PUT YOUR ACTION (Like Open cemara etc..)
    }
}

Résultat de l'autorisation de la poignée:

@Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
    super.onRequestPermissionsResult(requestCode, permissions, grantResults);
    boolean openActivityOnce = true;
    boolean openDialogOnce = true;
    if (requestCode == 11111) {
        for (int i = 0; i < grantResults.length; i++) {
            String permission = permissions[i];

            isPermitted = grantResults[i] == PackageManager.PERMISSION_GRANTED;

            if (grantResults[i] == PackageManager.PERMISSION_DENIED) {
                // user rejected the permission
                boolean showRationale = shouldShowRequestPermissionRationale(permission);
                if (!showRationale) {
                    //execute when 'never Ask Again' tick and permission dialog not show
                } else {
                    if (openDialogOnce) {
                        alertView();
                    }
                }
            }
        }

        if (isPermitted)
            if (isPermissionFromGallery)
                openGalleryFragment();
    }
}

Définir une alerte personnalisée:

private void alertView() {
    AlertDialog.Builder dialog = new AlertDialog.Builder(getActivity(), R.style.MyAlertDialogStyle);

    dialog.setTitle("Permission Denied")
            .setInverseBackgroundForced(true)
            //.setIcon(R.drawable.ic_info_black_24dp)
            .setMessage("Without those permission the app is unable to save your profile. App needs to save profile image in your external storage and also need to get profile image from camera or external storage.Are you sure you want to deny this permission?")

            .setNegativeButton("I'M SURE", new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialoginterface, int i) {
                    dialoginterface.dismiss();
                }
            })
            .setPositiveButton("RE-TRY", new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialoginterface, int i) {
                    dialoginterface.dismiss();
                    checkRunTimePermission();

                }
            }).show();
}

La meilleure description est sur: http://inthecheesefactory.com/blog/things-you-need-tknowknow-about-Android-m-permission-developer-edition/en

Pour les autorisations d'utilisation simples, vous pouvez utiliser cette bibliothèque: http://hotchemi.github.io/PermissionsDispatcher/

utiliser bibliothèque Dexter

Inclure la bibliothèque dans votre build.gradle

dependencies{
    implementation 'com.karumi:dexter:4.2.0'
}

cet exemple demande WRITE_EXTERNAL_STORAGE.

Dexter.withActivity(this)
                .withPermission(Manifest.permission.WRITE_EXTERNAL_STORAGE)
                .withListener(new PermissionListener() {
                    @Override
                    public void onPermissionGranted(PermissionGrantedResponse response) {
                        // permission is granted, open the camera
                    }

                    @Override
                    public void onPermissionDenied(PermissionDeniedResponse response) {
                        // check for permanent denial of permission
                        if (response.isPermanentlyDenied()) {
                            // navigate user to app settings
                        }
                    }

                    @Override
                    public void onPermissionRationaleShouldBeShown(PermissionRequest permission, PermissionToken token) {
                        token.continuePermissionRequest();
                    }
                }).check();

Pour l'autorisation d'exécution d'emplacement 

ActivityCompat.requestPermissions(this,new String[]{Android.Manifest.permission.ACCESS_FINE_LOCATION}, 1);

public void onRequestPermissionsResult(int requestCode, String permissions[], int[] grantResults) {
    switch (requestCode) {
        case 1: {
            // If request is cancelled, the result arrays are empty.
            if (grantResults.length > 0
                    && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                Log.d("yes","yes");

            } else {
                Log.d("yes","no");
                // permission denied, boo! Disable the

original (pas le mien) post ici

Pour les autorisations spéciales, telles que Android.Manifest.permission.PACKAGE_USAGE_STATS used AppOpsManager: 
Kotlin

private fun hasPermission(permission:String, permissionAppOpsManager:String): Boolean {
    var granted = false
    if (VERSION.SDK_INT >= VERSION_CODES.M) {
        // requires KitKat
        val appOps = applicationContext!!.getSystemService(Context.APP_OPS_SERVICE) as AppOpsManager

        // requires Lollipop
        val mode = appOps.checkOpNoThrow(permissionAppOpsManager,
                              Android.os.Process.myUid(), applicationContext!!.packageName)

        if (mode == AppOpsManager.MODE_DEFAULT) {
            granted = applicationContext!!.checkCallingOrSelfPermission(permission) == PackageManager.PERMISSION_GRANTED
        } else {
            granted = mode == AppOpsManager.MODE_ALLOWED
        }
    }

    return granted
}

et n'importe où dans le code: 

val permissionAppOpsManager = AppOpsManager.OPSTR_GET_USAGE_STATS
val permission = Android.Manifest.permission.PACKAGE_USAGE_STATS
val permissionActivity = Settings.ACTION_USAGE_ACCESS_SETTINGS

if (hasPermission(permission, permissionAppOpsManager)) {
    Timber.i("has permission: $permission")
    // do here what needs permission
} else {
    Timber.e("has no permission: $permission")
    // start activity to get permission
    startActivity(Intent(permissionActivity))
}
