我正在尝试构建我的Ionic应用程序以支持Android 12。它适用于Android 11，但不支持Android 12。
这就是我迄今为止所尝试的：
软件包.json
“cordova-android”: “^9.1.0”
build.gradle文件：
defaultBuildToolsVersion=“29.0.2”
defaultMinSdkVersion=22
defaultTargetSdkVersion=30
defaultCompileSdkVersion=30
config.xml文件：
preference name="android-targetSdkVersion" value="30"
===尝试将sdk增加到31===
package.json文件：
“cordova-android”: “^10.0.0”
build.gradle文件：
defaultTargetSdkVersion=31
defaultCompileSdkVersion=31
config.xml文件：
preference name="android-targetSdkVersion" value="31"
在..中的MainActivity中添加了android:exported="true"。。\platforms\android\app\src\main\AndroidManifest.xml
在运行此构建时，我得到以下错误：
FCMPlugin: Support for Gradle v4 or lower is deprecated. Please upgrade to a newer version.WARNING:: Configuration ‘compile’ is obsolete and has been replaced with ‘implementation’ and ‘api’.
It will be removed in version 7.0 of the Android Gradle plugin.
For more information, see Add build dependencies | Android Developers.
WARNING:: Using flatDir should be avoided because it doesn’t support any meta-data formats.

我试过所有的论坛和帖子，似乎都不起作用。有人知道怎么做吗？
有一个带有FCM插件的issue#222尚未解决，因此我可能建议您降低插件版本安装，直到修复为止。
