IonicBuildAndroidError

Hi,
I m build for android.
But app open my device waiting white screen

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.

could be the problem ?
emulator android==>4.3
ionic android==>6.2.2

No, current cordova-android versions are fine for Android 4.1 and newer.

but emulator is android 6.0 it’s run

See my first response to you.
Also post your ionic info output please.

Now I dont use real device,I can use emulator.
