Cordova debug build working fine. But signing apk produces white screen after splash screen

Already tried with creating new app and signing with the release key. But the same issue on signed apk.

cordova version - 7.1.0 
cordova platform android -> 7.1.0

How I can debug signed apk? to see errors on signed apk build. What could be the reason that produces a white screen on signing?

Thanks in advance!

回答1:

Most cases, it would be some plugin that is causing the issue with the target device. Now, how can you debug this

Load your cordova project in Android Studio
Run your project to the device directly.
Once the apk is installed and your cordova app is loaded, check your logcat for potential show stoppers (will be in red). Once you identify the root cause, you can work on making a fix.

Hope this helps.

回答2:

have you tried Android Debug Bridge (ADB)?

for example, on Ubuntu terminal, you can type:

adb logcat chromium:D SystemWebViewClient:D *:S

I guess It's a SSL certificate problem in server. It will work fine in debug mode, using expired ssl certification. But It will not working in Singed APK.

Check your server url to below link. https://www.digicert.com/help/
