I've recently asked a question and it was put on hold for being an Android Independent question.
I don't believe the question is actually Android Independent and it seems to fit the help center guidelines fairly
If your question generally covers...
Using your Android device
Using a particular app on your Android device
Trying to solve an error or other issue in using your Android device
While the technology in the question might not be completely finished yet, I think that it may very well become relevant in the future. However, I don't think this is a good enough reason to consider it off topic.
