Cordova ionic4-“；firebase analytics“；及；“admob免费”；在Android中导致错误

我用的是Ionic4。在我添加新插件之前，一切都很完美。请看一下我的步骤：-

1.我添加了以下插件，然后它就可以工作了

ionic cordova plugin add cordova-plugin-firebase-analytics

npm install @ionic-native/firebase-analytics

ionic cordova plugin add cordova-plugin-google-analytics

npm install @ionic-native/google-analytics

cordova plugin add cordova-android-play-services-gradle-release  --variable PLAY_SERVICES_VERSION=+

cordova plugin add cordova-android-firebase-gradle-release  --variable FIREBASE_VERSION=+

cordova plugin add cordova-android-support-gradle-release --variable FIREBASE_VERSION=+

ionic cordova plugin add cordova-plugin-androidx

ionic cordova plugin add cordova-plugin-androidx-adapter

ionic cordova plugin add cordova-plugin-admob-free --save --variable ADMOB_APP_ID=ca-xxxx

2.我添加了下面的插件，然后导致“IllegalStateException”

3.下面是cordova插件列表

cordova-android-firebase-gradle-release 4.0.0 "cordova-android-firebase-    gradle-release"
