Unity version：2021.3.7f1c1
I use unity as a android library. I create a TextureView to display unity screen as follow：

public class UnityView extends TextureView implements TextureView.SurfaceTextureListener {
 
........
 
    @Override
    public void onSurfaceTextureAvailable(SurfaceTexture surfaceTexture, int width, int height) {
      unityPlayer.displayChanged(0,  new Surface(surfaceTexture));
    }
 
    @Override
    public void onSurfaceTextureSizeChanged(SurfaceTexture surfaceTexture, int width, int height) {
      unityPlayer.displayChanged(0,  new Surface(surfaceTexture));
    }
 
    @Override
    public boolean onSurfaceTextureDestroyed(SurfaceTexture surfaceTexture) { 
      unityPlayer.displayChanged(0, null);
      return true;
    }
......
}

when app new and delete UnityView quickly， i got a crash.

when ID=0,displaychanged methold is:

    public boolean displayChanged(int var1, Surface var2) {
        if (var1 == 0) {
            this.mMainDisplayOverride = var2 != null;
            this.runOnUiThread(new Runnable() {
                public final void run() {
                    if (UnityPlayer.this.mMainDisplayOverride) {
                        UnityPlayer.this.removeView(UnityPlayer.this.mGlView);
                    } else {
                        UnityPlayer.this.addView(UnityPlayer.this.mGlView);
                    }
                }
            });
        }

        return this.updateDisplayInternal(var1, var2);
    }
