FileNotFoundException: open failed: EACCES (Permission denied)

Question

In emulator (i use genymotion) it works fine, but when I run it on a real device (my phone is ASUS ZenFone Laser 5.0) throws a filenotfoundexception

java.io.FileNotFoundException: /storage/emulated/0/cam20160926_075819.jpg: open failed: EACCES (Permission denied)

imgBitmap = MediaStore.Images.Media.getBitmap(cr, selectedImage);

here's the method onActivityResult()

@Override
    public void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        switch (requestCode){
            case CAMERA_REQUEST:
                if (resultCode == Activity.RESULT_OK){
                    Uri selectedImage = imageUri;
                    getActivity().getContentResolver().notifyChange(selectedImage, null);
                    ContentResolver cr = getActivity().getContentResolver();
                    Bitmap imgBitmap;
                    try {
                        imgBitmap = MediaStore.Images.Media.getBitmap(cr, selectedImage);

                        accountPhoto.setImageBitmap(imgBitmap);
                    } catch (IOException e) {
                        e.printStackTrace();
                        Toast.makeText(getActivity().getApplicationContext(), "Something went wrong while taking a photo", Toast.LENGTH_LONG).show();
                        Log.e("Camera", e.toString());
                    }

                }
        }
    }

i read some related questions and solutions about this EACCES, and it seems the problem is on my permission:

<uses-feature android:name="android.hardware.camera2" android:required="true"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" android:maxSdkVersion="18"/>
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />

am I missing something? thanks for responding

you have to request permission before you start your instructions because this permission is considered dangerous in Marshmallow:

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M && 
checkSelfPermission(Manifest.permission.WRITE_EXTERNAL_STORAGE) != PackageManager.PERMISSION_GRANTED) 
     {
      requestPermissions(new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE}, RESULT);
     } 
    else
     {
    //your code
     }
