These PDF library is commercial use?

I read this thread : https://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.

  • Try looking into GPL licences rather than PDF libraries, then you will have a better idea of what you will have to do to include it in your project. Here are some resources.
