JNI ERROR (app bug): local reference table overflow (max=512)

Hi：
First of all, I am sorry that I did not give feedback according to the format requirements, because I used a mobile phone to edit, it is difficult to translate and edit according to the format at the same time.
I'm using the latest version at (5.2.0).
When I frequently switch between the preview window and the remote video window, I find that it crashes, and some error messages are as follows:

I tried to fix the problem by adding the following method at the end of method "android_texture_display_set_window()" of file "android-texture-display.c":

(*env)->DeleteLocalRef(env, surfaceTextureClass);
(*env)->DeleteLocalRef(env, surfaceClass);
(*env)->DeleteLocalRef(env, textureViewClass);
(*env)->DeleteLocalRef(env, surface);
(*env)->DeleteLocalRef(env, windowId);

I don't know if there will be other exceptions with this modification, but this modification has solved my problem. If it is the correct solution, I hope you can fix it next time.

If this modification is wrong, I hope you can tell me the correct way to modify it.

Thank you very much
