Android: revoked permission

Question

Good afternoon. I'm trying to make an application capture an image and then display it in a gridview, but when I click a button to start recording this error, it appears.

Logcat:

java.lang.SecurityException: Permission Denial: starting Intent {
act=android.media.action.IMAGE_CAPTURE flg=0x3
cmp=com.android.camera2/com.android.camera.CaptureActivity
clip={text/uri-list
U:file:///storage/emulated/0/Pictures/MyInvoice/IMG_20160223_032401.jpg}
(has extras) } from ProcessRecord{8f9b88f
1356:com.example.labon.invoicemanger/u0a62} (pid=1356, uid=10062) with
revoked permission android.permission.CAMERA
at android.os.Parcel.readException(Parcel.java:1599)

My code is:

    myLists = new ArrayList<Images>();
    adapter = new ImageListAdapter(getActivity(), R.layout.img_list_view, myLists);
    Button myButton = (Button) view.findViewById(R.id.camerabutton);
    myButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
            fileUri = getOutputMediaFileUri(MEDIA_TYPE_IMAGE);// create a file to save the image
            intent.putExtra(MediaStore.EXTRA_OUTPUT, fileUri); // set the image file name
            startActivityForResult(intent, CAMERA_CAPTURE_IMAGE_REQUEST_CODE); // start the image capture Intent
        }
    });
    myGridView = (GridView) view.findViewById(R.id.gridView);
    myGridView.setAdapter(adapter);   /**
 * Create a file Uri for saving an image or video
 */
public Uri getOutputMediaFileUri(int type) {

    return Uri.fromFile(getOutputMediaFile(type));
}
/**
 * returning image /
 */
private static File getOutputMediaFile(int type) {

    // External sdcard location
    File mediaStorageDir = new File(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES), IMAGE_DIRECTORY_NAME);

    // Create the storage directory if it does not exist
    if (!mediaStorageDir.exists()) {
        mediaStorageDir.mkdirs();
        // if (!mediaStorageDir.mkdirs()) {
        Log.d(IMAGE_DIRECTORY_NAME, "Oops! Failed create "
                + IMAGE_DIRECTORY_NAME + " directory");
        //return null;

    }

    // Create a media file name
    String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss",
            Locale.getDefault()).format(new Date());
    File mediaFile;
    if (type == MEDIA_TYPE_IMAGE) {
        mediaFile = new File(mediaStorageDir.getPath() + File.separator
                + "IMG_" + timeStamp + ".jpg");
    } else {
        return null;
    }


    return mediaFile;


}


@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);


    switch (requestCode) {
        case 1:
            if (resultCode == Activity.RESULT_OK) {
                Uri selectedImage = data.getData();
                String[] filePathColumn = {MediaStore.Images.Media.DATA};
                Cursor cursor = getActivity().getContentResolver().query(selectedImage, filePathColumn, null, null, null);
                cursor.moveToFirst();

                int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
                //file path of captured image
                String filePath = cursor.getString(columnIndex);
                //file path of captured image
                File f = new File(filePath);
                String filename = f.getName();
                cursor.close();

                //Convert file path into bitmap image using below line.
                Bitmap yourSelectedImage = BitmapFactory.decodeFile(filePath);
                //put bitmapimage in your imageview
                ImageView imageView = (ImageView) view.findViewById(R.id.imageListView);
                imageView.setImageBitmap(BitmapFactory.decodeByteArray(images.getImageBlob(), 0, images.getImageBlob().length));
                //newImageView.setImageBitmap(yourSelectedImage);  }
    if (resultCode == getActivity().RESULT_CANCELED) {
        // user cancelled Image capture
        Toast.makeText(getActivity(), "User cancelled image capture", Toast.LENGTH_SHORT)
                .show();
    } else {
        // failed to capture image
        Toast.makeText(getActivity(), "Sorry! Failed to capture image", Toast.LENGTH_SHORT)
                .show();
    }
} }

Answer 1

Do you use this on marshmallows? Because if you, the structure of permission has changed. And you should read the documentation @ http://developer.android.com/training/permissions/index.html .

The user must grant permission explicitly.

Answer 2

you need to add user permission on androidmanifest.xml

<uses-permission android:name="android.permission.CAMERA" />

, :

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
