We could do the encoding for the "icon" here, and just pass in a String.

[pkotwicz, 2016/06/06 21:29:24]

We could. I think that the fact that buildWebApkAsync() sends an intent in an
implementation detail so I would rather not. In the final version,
buildWebApkAsync() will send data to a server and not send an intent

[Xi Han, 2016/06/07 13:20:37]

You are right, we should keep the Bitmap.
