Thank You StackOverflow.

After looking for 4 hours on internet and stackoverflow, searching whole documentation and blog pages, i didn't find a solution to an error I was getting in my Android app.
So I began and started writing the question on StackOverflow, phrasing it properly, to the point (so as to not get downvoted), providing all my files and code (so not to get closed or duplicate), formatting them properly, and explaining why my error was unique. On the last XML file I see something trying to call a function which wasn't declared.

So yeah, there you go.

But it's not over yet.
I saw it and got excited, corrected it and ran the code again. But accidentally ran it on the emulator and forgot my device wasn't connected anymore, and the emulator wasn't already loaded either. And my machine is old.

I don't know what to say anymore.
