 So a while back I am checking out this application this simple voice recorder on fdroid on fdroid It's labeled that it has an Apache license, but when you go to the github page. It's licensed in a gpl so I Open up a little report on this and I state just that on fdroid saying this is Apache on github It's saying it's gpl. There's one way compatibility, so Apache can be released as a gpl But I'm pretty sure gpl can't go to a Apache license I just want to make sure that I know what license this is under properly the creator of the project says It is wrong in fdroid meaning it is a gpl license About a month later somebody else comes in and asks so can I use this code? I mean I will change it, but can I use it this code like a base code for my app? So I come back and explain well it depends on the license You're going to use on your project since this is a gpl license You have to use a gpl version 3 or a compatible license Otherwise no, you can't and I give him some references then the creator of the project comes back and says I definitely don't support app editing and republishing I'm confused
