Could you show your code as an example?

And is requestRender called?

I have created a separate activity "ScreenPublisherActivity" to just draw the screen preview. Not able to figure out why nothing gets drawn on the texture view.

I check and the onFrameAvailable is not called, I am wondering why

It seems that the surface in ImageReader works fine. Need to look into the source code of it.

I try to use

                surfaceTexture.setDefaultBufferSize(width, height);

And it works.
Add this line before set onFrameAvailable listener:

        displayTextureView.setSurfaceTextureCreatedListener(new GLMultiTexProducerView.SurfaceTextureCreatedListener() {
            @Override
            public void onCreated(List<GLTexture> producedTextureList) {
                GLTexture texture = producedTextureList.get(0);
                surfaceTexture = texture.getSurfaceTexture();
                RawTexture outsideTexture = texture.getRawTexture();
                width = outsideTexture.getWidth();
                height = outsideTexture.getHeight();
                surfaceTexture.setDefaultBufferSize(width, height);
                surfaceTexture.setOnFrameAvailableListener(new SurfaceTexture.OnFrameAvailableListener() {
                    @Override
                    public void onFrameAvailable(SurfaceTexture surfaceTexture) {
                        Log.i(TAG, "onFrameAvailable");
                        displayTextureView.requestRender();
                    }
                }, mHandler);
                mSurface = new Surface(surfaceTexture);
                if(mVirtualDisplay != null) {
                    mVirtualDisplay.setSurface(mSurface);
                }
            }
        });
