Android page curl with images streaming from web? -
so, using https://github.com/harism/android_page_curl , project achieve curl functionality create book. want achieve same while streaming images web directly, in asynchronous manner.
but require opengl , progress bar same. don't have knowledge in opengl, how can go tweaking code , achieve functionality want.
also , have @ question more clear view of want achieve...

also , using android-query library asynchronous image/file loading. feasible use project in case of streaming images web. how?
