APK stops after try to open in Android 4.4.4

Hello, after ionic cordova emulate android my apk was built successfully. Then I sent it to my Android ./adb install -r debug-app.apk. But after that, when I click to open myApp, a message appears “The MyApp stopped”.

Example:

What’s wrong? The app runs fine on emulator, and the apk was built with no errors. I am using Android 4.4.4 (Samsung Galaxy Gran Prime 4G).

Suggestions?

Note: when I make use firebase in Ionic, is necessary to install either npm install firebase angularfire2 --save or ionic cordova plugin add cordova-plugin-firebase && npm install --save @ionic-native/firebase? If I execute both commands, could have some conflict?

Old, update it.

Your Cordova tooling seems to be out of date, which might be causing all kinds of problems.
