Permission Denial: MediaDocumentsProvider

I am getting the following exception when trying to display a URI. I think it occurs after my activity is stopped and I try to access a viable URI again. There are other questions addressing this problem but I am very confused as to how to apply any solutions to my code since my takePhotoIntent allows for a picture to either be taken or chosen from gallery (found below).

Unable to open content: content://
java.lang.SecurityException: Permission Denial: reading uri
content:// from pid=821, uid=10238 requires android.permission.MANAGE_DOCUMENTS, or grantUriPermission()

My createImageFile and my takePhotoIntent:

private File createImageFile() throws IOException {
// Create an image file name
String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
String imageFileName = "JPEG_" + timeStamp;
File storageDir = getExternalFilesDir(Environment.DIRECTORY_PICTURES);
File image = File.createTempFile(
imageFileName, /* prefix */
".jpg", /* suffix */
storageDir /* directory */

// Save a file: path for use with ACTION_VIEW intents
mCurrentPhotoPath = "file:" + image.getAbsolutePath();
return image;

private void dispatchTakePictureIntent() {
for(int i = 0; i < 4; i++) {
Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
if (takePictureIntent.resolveActivity(getPackageManager()) != null) {
// Create the File where the photo should go
File photoFile = null;
try {
photoFile = createImageFile();
outputFileUri = Uri.fromFile(photoFile);
} catch (IOException ex) {
}catch (NullPointerException nullEx) {
// Camera.
final List<Intent> cameraIntents = new ArrayList<Intent>();
final Intent captureIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
final PackageManager packageManager = getPackageManager();
final List<ResolveInfo> listCam = packageManager.queryIntentActivities(captureIntent, 0);
for (ResolveInfo res : listCam) {
final String packageName = res.activityInfo.packageName;
final Intent intent = new Intent(captureIntent);
intent.setComponent(new ComponentName(res.activityInfo.packageName,;
intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(photoFile));
// Filesystem.
final Intent galleryIntent = new Intent();
// Chooser of filesystem options.
final Intent chooserIntent = Intent.createChooser(galleryIntent, "Select Source");
// Add the camera options.
chooserIntent.putExtra(Intent.EXTRA_INITIAL_INTENTS, cameraIntents.toArray(new Parcelable[cameraIntents.size()]));
startActivityForResult(chooserIntent, REQUEST_HAPPY_PHOTO);
startActivityForResult(chooserIntent, REQUEST_SURPRISED_PHOTO);
startActivityForResult(chooserIntent, REQUEST_AFRAID_PHOTO);
startActivityForResult(chooserIntent, REQUEST_UPSET_PHOTO);
startActivityForResult(chooserIntent, REQUEST_SAD_PHOTO);

Per the Storage Access Framework client documentation:

  • Use ACTION_GET_CONTENT if you want your app to simply read/import data. With this approach, the app imports a copy of the data, such as an image file.

  • Use ACTION_OPEN_DOCUMENT if you want your app to have long term, persistent access to documents owned by a document provider. An example would be a photo-editing app that lets users edit images stored in a document provider.

As you are using ACTION_GET_CONTENT, your access to the Uri ends when the component is destroyed (unless you pass the Uri to a new component). You must make a copy of the file from the Uri if you'd like to continue to access it beyond the lifetime of your component or switch to ACTION_OPEN_DOCUMENT and persist permissions (possible only with document Uris).
