Given the plethora of Apache 2.0 libraries used to create many proprietary Android apps, how/where should we refer to the Apache License?
- Should we mention Apache license at Google Play, presenting a link to the full license?
- Mention in Google Play is enough or we also must add it into the installed APK?
- Should the binary contain the full license or a link is enough?
- Should each Apache library be discriminated (like Instagram) or simply mention it once is enough to cover all Apache dependencies?
