Android 6(m) Permission Issue (create Directory Not Working)

I have this code for creating directory for saving pictures: File storageDir = null; if (Environment.MEDIA_MOUNTED.equals(Environment.getExternalStorageState())) {

Solution 1:

As @CommonsWare answered, there is run-time permission asking concept on Android M, so in new approach, permissions are not asked when installing the app but when trying to use specific feature of phone which requests permission, at run-time. User later can disable permission from phone settings->app->yourapp->permissions as well. So you have to check before doing something with that permission, and ask user:

int REQUEST_WRITE_EXTERNAL_STORAGE=1;
////...
        File storageDir = null;
        if (Environment.MEDIA_MOUNTED.equals(Environment.getExternalStorageState())) {
            //RUNTIME PERMISSION Android Mif(PackageManager.PERMISSION_GRANTED==ActivityCompat.checkSelfPermission(context,Manifest.permission.WRITE_EXTERNAL_STORAGE)){
                storageDir = new File(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES), "myPhoto");
            }else{
                requestPermission(context);
            }    

        } 
        return storageDir;
////...privatestaticvoidrequestPermission(final Context context){
        if(ActivityCompat.shouldShowRequestPermissionRationale((Activity)context,Manifest.permission.WRITE_EXTERNAL_STORAGE)) {
            // Provide an additional rationale to the user if the permission was not granted// and the user would benefit from additional context for the use of the permission.// For example if the user has previously denied the permission.new AlertDialog.Builder(context)
                    .setMessage(context.getResources().getString(R.string.permission_storage))
                    .setPositiveButton(R.string.tamam, new DialogInterface.OnClickListener() {
                @Override
                publicvoidonClick(DialogInterface dialog, int which) {
                    ActivityCompat.requestPermissions((Activity) context,
                            new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE},
                            REQUEST_WRITE_EXTERNAL_STORAGE);
                }
            }).show();

        }else {
            // permission has not been granted yet. Request it directly.
            ActivityCompat.requestPermissions((Activity)context,
                    new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE},
                    REQUEST_WRITE_EXTERNAL_STORAGE);
        }
    }

///...

    @Override
    publicvoidonRequestPermissionsResult(int requestCode,String permissions[], int[] grantResults) {
        switch (requestCode) {
            case UtilityPhotoController.REQUEST_WRITE_EXTERNAL_STORAGE: {
                if (grantResults.length == 1 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                    Toast.makeText(context,
                            getResources().getString(R.string.permission_storage_success),
                            Toast.LENGTH_SHORT).show();

                } else {
                    Toast.makeText(context,
                            getResources().getString(R.string.permission_storage_failure),
                            Toast.LENGTH_SHORT).show();
                    super.onRequestPermissionsResult(requestCode, permissions, grantResults);
                }
                return;
            }
        }
    }

Solution 2:

You are running this on an Android 6.0+ environment and you have a targetSdkVersion of 23.

In that case, WRITE_EXTERNAL_STORAGE is part of the Android 6.0 runtime permission system. Either revise your app to participate in this system, or drop your targetSdkVersion below 23.

Solution 3:

You must get permission for this work like:

for do it impliment this code:

if (ContextCompat.checkSelfPermission(this,
            Manifest.permission.WRITE_EXTERNAL_STORAGE)
            != PackageManager.PERMISSION_GRANTED) {

        if (ActivityCompat.shouldShowRequestPermissionRationale(this,
                Manifest.permission.WRITE_EXTERNAL_STORAGE)) {

        } else {


            ActivityCompat.requestPermissions(this,
                    new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE},23
                    );
        }
    }

good luck!!!

Solution 4:

Try this code.

@OverrideprotectedvoidonCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);

             if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
                            if (checkPermission()) {
                                //do your work
                            } else {
                                requestPermission();
                            }
                        }
               }


                protectedbooleancheckPermission() {
                    int result = ContextCompat.checkSelfPermission(this, android.Manifest.permission.WRITE_EXTERNAL_STORAGE);
                    if (result == PackageManager.PERMISSION_GRANTED) {
                        returntrue;
                    } else {
                        returnfalse;
                    }
                }

                protectedvoidrequestPermission() {

                    if (ActivityCompat.shouldShowRequestPermissionRationale(this, Manifest.permission.WRITE_EXTERNAL_STORAGE)) {
                        Toast.makeText(this, "Write External Storage permission allows us to do store images. Please allow this permission in App Settings.", Toast.LENGTH_LONG).show();
                    } else {
                        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
                            requestPermissions(newString[]{Manifest.permission.WRITE_EXTERNAL_STORAGE}, 100);
                        }
                    }
                }

            @OverridepublicvoidonRequestPermissionsResult(int requestCode, String permissions[], int[] grantResults) {
                switch (requestCode) {
                    case100:
                        if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                            //do your work
                        } else {
                            Log.e("value", "Permission Denied, You cannot use local drive .");
                        }
                        break;
                }
            }
