Throws RuntimeExeption: Initialize GlideFaceDetector about glidefacedetectiontransformation HOT 7 CLOSED

If you have got RuntimeException with this message Initialize GlideFaceDetector by calling GlideFaceDetector.initialize(context)., it means you have not initialized the GlideFaceDetector before calling FaceCenterCrop().

Also, if you have released the detector by calling GlideFaceDetector.releaseDetector(); then you will have to re-initialize the detector.

Please add some code for better debugging the problem.

I have a recyclerView which loads images with glide. I have initialized GlideFaceDetector in my onCreate() method. Released it in the onDestroy() method and no where else. The exception occurs only when i open a detail of the image and close it and try to scroll the recyclerView again.

I have even tried calling GlideFaceDetector.initialize(context) inside onResume() method. But still the same error. Its a common setup with a recyclerView and ListViewHolder to open up an activity on click. Nothing extra in the code to be shared here.

Are you using the recyclerView inside a fragment? And is the detail of the image also a fragment?

from glidefacedetectiontransformation.

It is a single activity without fragments anywhere in it. The activity houses the recyclerView and the recyclerView uses a normal view which has this image and a textview. Typical setup.

There is no issue with launching this activity with the recyclerView using FaceCenterCrop for the first time. It only happens when you start another activity from it and return back to it and scroll the recyclerView which causes the onBindViewHolder to call Glide to load the next image to the viewHolder which causes the crash since the FaceCenterCrop() Transformation does not seem to keep the GlideFaceDetector.initialize(context) alive between activity switches. That will be my guess to whats happening here.

And Thanks for your quick replies Rohit.

Are you releasing the detector in the image detail (second) activity? If yes, then that might be the cause of the crash because GlideFaceDetector maintains a singleton instance and you should release the detector only when you are done with it. Else you will have to re-initialize the GlideFaceDetector to use again.

Thanks Rohit. That seems to solve the problem.
But it gets hard to maintain this behaviour when you have to check whether to release the GlideFaceDetector or not in that activity as it could be called from many places within the app wherein I may not be initializing GlideFaceDetector in the activity that calls this detail activity. But anyway some extras with the intent passed to open the detail activity should work for now.

Kudos!

Yes @jishincreo , I agree with you.

Just treat the GlideFaceDetector as a singleton instance (which actually is right now). Will try to improve it's lifecycle in further releases.
