报错背景：升级了androidstudio跑老项目...

One or more issues found when checking AAR metadata values:

查看这个文件：

aarFormatVersion=1.0
aarMetadataVersion=1.0
minCompileSdk=32  //最小CompileSdk是32，而我的是30，不符合规则
minCompileSdkExtension=0
minAndroidGradlePluginVersion=1.0.0

线索2：

Dependency: androidx.appcompat:appcompat-resources:1.5.0.

结合线索1就是，想要依赖 androidx.appcompat:appcompat-resources:1.5.0.，compilesdk必须大于等于32，那我们猜想把这个库的版本降低应该就能解决问题，但全局搜索发现我们自己并没有直接依赖这个库，所以我们使用as自带的工具查看依赖关系：

 

最终发现是

'com.google.android.material:material:1.6.0'

中依赖

androidx.appcompat:appcompat-resources:1.5.0.

导致的问题，所以降低material的版本直到符合编译检查。

同理，可以按照此方法逐个排查此类问题。
