java.lang.SecurityException: Permission Denial: reading com.android.providers.media.MediaProvider in Android while taking picture from gallery

android

Solution

For checking manual permissions for API level 23 and above i use this code.

public static final int MY_PERMISSIONS_REQUEST_READ_EXTERNAL_STORAGE = 123;

public boolean checkPermissionREAD_EXTERNAL_STORAGE(
            final Context context) {
        int currentAPIVersion = Build.VERSION.SDK_INT;
        if (currentAPIVersion >= android.os.Build.VERSION_CODES.M) {
            if (ContextCompat.checkSelfPermission(context,
                    Manifest.permission.READ_EXTERNAL_STORAGE) != PackageManager.PERMISSION_GRANTED) {
                if (ActivityCompat.shouldShowRequestPermissionRationale(
                        (Activity) context,
                        Manifest.permission.READ_EXTERNAL_STORAGE)) {
                    showDialog("External storage", context,
                            Manifest.permission.READ_EXTERNAL_STORAGE);

                } else {
                    ActivityCompat
                            .requestPermissions(
                                    (Activity) context,
                                    new String[] { Manifest.permission.READ_EXTERNAL_STORAGE },
                                    MY_PERMISSIONS_REQUEST_READ_EXTERNAL_STORAGE);
                }
                return false;
            } else {
                return true;
            }

        } else {
            return true;
        }
    }

showDialog()

public void showDialog(final String msg, final Context context,
            final String permission) {
        AlertDialog.Builder alertBuilder = new AlertDialog.Builder(context);
        alertBuilder.setCancelable(true);
        alertBuilder.setTitle("Permission necessary");
        alertBuilder.setMessage(msg + " permission is necessary");
        alertBuilder.setPositiveButton(android.R.string.yes,
                new DialogInterface.OnClickListener() {
                    public void onClick(DialogInterface dialog, int which) {
                        ActivityCompat.requestPermissions((Activity) context,
                                new String[] { permission },
                                MY_PERMISSIONS_REQUEST_READ_EXTERNAL_STORAGE);
                    }
                });
        AlertDialog alert = alertBuilder.create();
        alert.show();
    }

in your activity check like this.

if (checkPermissionREAD_EXTERNAL_STORAGE(this)) {
            // do your stuff..
        }

And don't forget to add `onRequestPermissionsResult`.

@Override
    public void onRequestPermissionsResult(int requestCode,
            String[] permissions, int[] grantResults) {
        switch (requestCode) {
        case MY_PERMISSIONS_REQUEST_READ_EXTERNAL_STORAGE:
            if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                // do your stuff
            } else {
                Toast.makeText(Login.this, "GET_ACCOUNTS Denied",
                        Toast.LENGTH_SHORT).show();
            }
            break;
        default:
            super.onRequestPermissionsResult(requestCode, permissions,
                    grantResults);
        }
    }

Happy Coding..
