Ionic got white blank after splash screen in build apk for android

i have a problem, when i build my app to apk to be blank but before i try to run with command ionic cordova run android data from my app out and work normally as usual , can help me please?

Did you remote debug the problem on the device already? Follow these instructions here to debug the problem in Chrome dev tools: https://ionic.zone/debug/remote-debug-your-app#android Look at the console and network tabs for errors.

sure, i have done it but there is no error problem in my application when in debug but after i make my app to apk i can issue white blank

You can also create a debug build as an .apk that is debuggable.
