[Solved] App aparece mensagem “app parou” [closed]

Question

you haven’t provided any log details.
Search your log for “fatal” and look for the main, its the best and the most direct lead to your problem.

But from my experience some common mistakes causing this sort of problems are using the android: nameSpace instead of app: for AppCompat components in your xml files or using non compat components or even methods that are introduced in APIs higher than your minimum SDK.

you’re not paying attention to the warnings of the IDE about anything that is either deprecated or is only supported from an specific API and higher.

Never ignore IDE warnings.
They didn’t put them there just for decorating purposes.

And in case of your signed Apk, never sign it just using V2 Signature because older versions of android will have problems parsing it
