I'm trying to build my app for developing purpose, It worked before but when I'm trying to build it on a new computer Google Play Protect blocks my app.

My application is build on Ionic 4, on a new computer (I develop it on another computer).

I tried to build it with debug option but it didn't work.

I did a research and found some answers, this was the most logical: Debug app blocked by play protect

I tried to delete the debug key from the ~/.android/ directory and after it didn't work I tried to delete all cache data from the ~/android/ directory.

I also saw this question installation app blocked by play protect but he had problem with release apk and not with debug apk as I have.

How am I trying to build:

ionic cordova build android --prod --debug

After it didn't work I tried to clean my configuration:

cordova clean

didn't work either.

The error message that I get is that the app developer isn't recognize to google.

Expected result is: be able to install debug application for developing purpose.

    Debug signingConfigs are machine specific. If you sign a debug apk on 2 computers you will end up with 2 apks that google thinks come from different sources. What you want is possible by creating a keystore file for debugging purposes and configure gradle to use that keystore in the debug buildtype. You will have to reinstall the current app first – Tim Aug 02 '19 at 12:32
  • @TimCastelijns I don't have the previous keystore, so I tried to install the app with `ionic run` it works, but I'm still unable to install it after build for the same reason. – Code Warrior Aug 02 '19 at 13:18
  • Are you trying to update your app, I mean your app is available on play store? – user9088454 Aug 02 '19 at 14:08
  • @user9088454 No, I haven't published it yet. it still under development – Code Warrior Aug 02 '19 at 14:09
  • then create a new ionic 4 project and put your src there and install the plugin if you added – user9088454 Aug 02 '19 at 14:16
  • for someone who will come here in the future, After all what I did I think I was needed a restart and that's was what let me install the app, I'm still getting the error on first installtion but now I can skip it and install it anyway – Code Warrior Aug 02 '19 at 18:40
  • Btw: You can deploy the debug build to your own phone using the commandline. Connect the device via usb, and use `ionic cordova run android` – rtpHarry Aug 07 '19 at 04:51
