**Current behavior:**
Cordova has recently released cordova-android@10.1.0, which supports android 11 and targets API level 30. This is important, because by August 2021, all new Android apps must target at least Android 11 (API level 30). By November 2021, all apps that are being updated must target at least Android 11 (API level 30).
I wanted to upgrade the cordova-android version in my ionic app from v9.1.0 to v10.1.0 and most of it went smoothly. Unfortunately, the google maps plugin is not working. When I run it on my device I currently get a white screen. I'm using the multiple_maps branch to ensure that the AndroidX support libraries are used.

My app is huge, so I've created a new small ionic project, where I only am adding the cordova-plugin-googlemaps plugin. When I install it on my phone and use cordova-android@9.1.0 it works like a charm. When I then upgrade the cordova-android version to v10.1.0 and install it on my phone, I get a white screen in google maps.

To test the same behaviour, here's the [link](https://github.com/jokerengine/ionicapp-cordovaandroid10-googlemaps) to my GitHub project.

**Expected behavior:**
I suspect that a fix needs to be made with the plugin, so that it is compatible with cordova-android@10.1.0

Any help would really be appreciated. Thanks so much!

Start with the linked reproduction project and compare its behavior on cordova-android@9.1.0 and @10.1.0, using the listed cordova-plugin-googlemaps version and the multiple_maps branch. Check the plugin's Android integration and runtime logs to isolate the white screen; done means the reproduction displays Google Maps on cordova-android@10.1.0 without regressing the older version.
