웹뷰내 플래쉬 문제로 앱이 사망 

오류 Failed change in drawing model due to missing context


- 하드웨어 가속으로 처리 하였으나 바탕이 검정색으로 오류



However, if in your AndroidManifest.xml contains:

             android:hardwareAccelerated="true"
아래 코드를 통해 수정...
           webView.setBackgroundColor(0x00FFFFFF);



webView's background, for some reason, does not change to transparency.
(It took me while to figure this out!)

This is how to disable hardware acceleration on the view that contains webview:

             view.setLayerType(View.LAYER_TYPE_SOFTWAREnull);
