Pergunta
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.
Solução
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.

If you just want to know if you can use a GPL library in a commercial, closed-source application without paying a single cent, then the answer is no, you cannot.
