Q:

Release APK error Android Studio

I generated the unsigned release APK in Android Studio and it does not work. I run my app in debug on my phone and it works perfectly, but the release apk does not.
The app just haves to show simple text in textviews and it does not ... I do not know what to do.
Please help

A:

Sign it.  All apks, including debug ones, must be signed to be used.  The debug ones just use an automatically generated keystore for signing.
