App unfortunately stooped on real android device

I have developed one app in ionic 3, which works fine in browser. Is it working good before Jun 16,2019. Now it is unfortunately stopped on android device.

After 16 june is showing build error so I tried below steps

> ionic cordova platform rm android
> ionic cordova platform add android@8.0.0 
> ionic cordova plugin add cordova-plugin-androidx 
> ionic cordova plugin add cordova-plugin-androidx-adapter

cordova plugin add cordova-android-support-gradle-release --save

then is successfully built but ‘Unfortunately stopped on device’.

Is their any way to get error message for stopping?? Please help me
