These PDF library is commercial use?
I read this thread : http://stackoverflow.com/questions/4665957/pdf-parsing-library-for-android .

Vikas Patidar mentions that there are some open source library on Android like

 - Android PDF Viewer
 - APDFViewer
 - droidreader
 - android-pdf

Some of them are licensed with GNU GPL v2. Some of them are licensed with GNU GPL v3.
I want to ask whether they can be used in a commercial applcation.

Thanks.
