I'm trying to figure out how I would get the data in a Firebase database assigned to a particular user but that is proving very tricky for me.
So, for now, I would like to be able to attach the current signed-in/authenticated user's name/ID to any file that I save from my app but I don't know how to go about it.
I tried adding the following lines to my Camera Photo activity but it didn't do anything:
public void onStart() {
super.onStart();
FirebaseUser currentUser = mAuth.getCurrentUser();
updateUI(currentUser);
and then adding to the code where it assigns the file name (as such):
file = new File(Environment.getExternalStorageDirectory() + "/" + UUID.randomUUID().toString()
+ FirebaseAuth.getInstance().getCurrentUser() + ".jpg");
But, as I say, it doesn't do anything and just keeps the file name in the same format without any user ID associated with it.
Below is the full class for taking and saving a photo (without my added attempts):
public class CameraPhotoActivity extends AppCompatActivity {
private Button btnCapture;
private TextureView textureView;
// to check the state orientation of the output image
private static final SparseIntArray ORIENTATIONS = new SparseIntArray();

Again, any help and advice greatly appreciated.

If you want to add the user name in the name of your file, you need to change this line of code:
file = new File(Environment.getExternalStorageDirectory()
+ "/" + UUID.randomUUID().toString()
+ FirebaseAuth.getInstance().getCurrentUser() + ".jpg");
with
file = new File(Environment.getExternalStorageDirectory()
+ "/" + UUID.randomUUID().toString()
+ FirebaseAuth.getInstance().getCurrentUser().getDisplayName() + ".jpg");
See, I have added a call to .getDisplayName() method.

i am making an app that records a video and then displays this video on another activity.
the problem is that this video cannot be played right away, i would have to record the video, and then restart the android app for it to show. otherwise it shows me a message that
says: "can't play this video".
Moreover the thing that i really dont understand is that i tried it on an older phone of android version 11 and it works perfectly, but for some reason on the new phone it doesn't
i have made some research and i think it has something to do with the storage permissions but i am not sure since i tried fixing it with no luck.
what can i do to fix this?

Exception i am getting is as below:
java.lang.NullPointerException: Attempt to invoke virtual method 'void android.hardware.camera2.CameraDevice.close()' on a null object reference
I am getting exception on this line:
cameraDevice1.close();
Which of the cameraDevice1.close() calls fails? Did you ever get an onOpened call for that camera?
There's no guarantee that a given Android device can have multiple cameras open at once; the only way to know is to try, and if it can't be done, the second camera will not fire onOpened, it'll fire onError with error code TOO_MANY_CAMERAS_IN_USE.
So if that's happening here, then you'll get onError without onOpened, and your cameraDevice1 will never have been set.

I have written this code for the front camera but it is not working in all Android devices, in some devices it reboots the phone and in some devices it shows an unfortunate error and in some devices it works properly.
