The application runs but when i try to use the camera only a disturbed grey screen appears and the logs tab gives me two errors:
E/libc: Access denied findin
First, check your Android version. If it is running on Android 6.0 and higher (API level 23+), then you need to :
Declare a permission in the app manifest. Make sure to insert the permission above the application tag.
...
Then, request that the user approve each permission at runtime
if (ContextCompat.checkSelfPermission(context, Manifest.permission.CAMERA) !=
PackageManager.PERMISSION_GRANTED) {
ActivityCompat.requestPermissions(this, new String[] {Manifest.permission.CAMERA},
50); }
