Finally ADC 2 closed, I could have a good night sleep today.  Right before the closure, I submitted following changes.   1.Color Picker Sphere now has a small circle showing where to click to confirm selection.  Coding OpenGL is fun :)    2. A bit performance improvement.  Thanks to the great log/tool making it as easy as ABC.   A: Add a log point    // Method tracing to "/sdcard/requestPage.trace"  Debug.startMethodTracing("requestPage"); //Code's subjected to profiling  // Stop Method tracing            Debug.stopMethodTracing();   B: Visualize  >traceview requestPage.trace   C.Working on the hot spots   3.Change webView loading & a few cosmetic stuffs     webView.loadDataWithBaseURL(...   instead of      webView.loadData(...   Turns out that loadData() actually loading data as a data:Uri way, which is not really good for some unicode data
