I know there are a few questions regarding the same but none of it answers my issue.

I’ve a CustomTextureView as follows:

public class CustomTextureView extends TextureView
{
   public CustomTextureView( Context context )
   {
      super( context );
      Log.e( "droidtag", "CustomTextureView created");
   }

   public void setListener()
   {
      setSurfaceTextureListener( new CustomTextureViewListener() );
   }

    private class CustomTextureViewListener implements SurfaceTextureListener
    {

        @Override
        public void onSurfaceTextureAvailable(final SurfaceTexture surfaceTexture, final int width, final int height)
        {
             Log.e( "droidtag", "CustomTextureView onSurfaceTextureAvailable");
        }

        @Override
        public void onSurfaceTextureSizeChanged(SurfaceTexture surfaceTexture, int width, int height)
        {
            Log.e( "droidtag", "CustomTextureView onSurfaceTextureSizeChanged");
        }

        @Override
        public boolean onSurfaceTextureDestroyed(SurfaceTexture surfaceTexture)
        {
            Log.e( "droidtag", "CustomTextureView onSurfaceTextureDestroyed");
            return true;
        }

        @Override
        public void onSurfaceTextureUpdated(SurfaceTexture surfaceTexture)
        {
            Log.e( "droidtag", "CustomTextureView onSurfaceTextureUpdated");
        }
    }

    @Override
    protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
        super.onMeasure(widthMeasureSpec, heightMeasureSpec);
        int width = MeasureSpec.getSize(widthMeasureSpec);
        int height = MeasureSpec.getSize(heightMeasureSpec);
        Log.e("droidtag", "CustomTextureView::onMeasure() called with width = " + width + " and height = " + height);
        setMeasuredDimension(width, height);
    }
}

Now I’ve a ViewHeirarcy with custom classes as follows:
ViewRoot -> RelativeLayout -> LinearLayout

I create the CustomTextureView in the constructor of my custom class which extends LinearLayout.

I get the onSurfaceTextureAvailable callback for this. But, after doing stuff in native side I call a function:

public void resetTextureView()
{
      if( mCustomTextureView != null )
      {
         if( mCustomTextureView.getParent() != null )
         {
            ( ( ViewGroup )mCustomTextureView.getParent() ).removeView( mCustomTextureView );
         }

         mCustomTextureView = null;
      }
      mCustomTextureView = new CustomTextureView( getContext() );
      this.addView( mCustomTextureView );
      LayoutParams params = LayoutParams mCustomTextureView.getLayoutParams();
      params.height = 200;
      params.width = 200;
      mCustomTextureView.setLayoutParams(params);
      mCustomTextureView.setListener();
      this.invalidate();
}

This never calls onSurfaceTextureAvailable, however I when I change it to its parent i.e
this.addView( mCustomTextureView ) to this.getParent().addView( mCustomTextureView ) I get the callback as expected.

Some of the already existing solutions does not seem to be the issue:

• The app is hardware accelerated
• All of them are VISIBLE(from getVisibility) and have non zero height and width.
• dispatchDraw on the LinearLayout gets called as intended and CustomTextureView.onMeasure is also called – in all the cases.

Also, I can actually see the newly created CustomTextureView on screen – the gray part:

Any pointers or suggestions as to why I’m not getting the onSurfaceTextureAvailable callback will be helpful. Please do ask for additional information if necessary.

Thanks
