Additional requirements
Migrate cordova-plugin-printer to last Android SDK
We use “cordova-plugin-printer” to print in the App since the WebView cannot print by itself.
The last version of this plugin was “0.8.0” till the publishing of this sample.
To meet the last Android SDK change and requirement (https://developer.android.com/jetpack/androidx/migrate) we MUST fix the issue #283 (https://github.com/katzer/cordova-plugin-printer/issues/283) manually as this commit (https://github.com/mi-corporation/cordova-plugin-printer/commit/091a9b58eddfa3fe7e2be5702f33d6e8b345f714).
After the first build, you’ll find the source at:
UDTTCordovaProject/platforms/android/app/src/main/java/de/appplant/cordova/plugin/printer
