Used official Android deployment tutorial on help(F1) and built APK, game not working.

After spending a really long time to do everything from the deployment tutorial on the help file, while building the APK, I got these warnings:

[javac] warning: [options] source value 1.5 is obsolete and will be removed in a future release
[javac] warning: [options] target value 1.5 is obsolete and will be removed in a future release
[javac] warning: [options] To suppress warnings about obsolete options, use -Xlint:-options.
[javac] 3 warnings

The build completed normally, I got the ARM and X86 APKs, ran them on my phone, but only the title screen appeared for a few seconds and then freeze and app crashed. Would appreciate some advice, thanks.
