问题：

使用 implementation ‘androidx.appcompat:appcompat:1.7.0’
出现无法运行的问题，编译都没有问题

解决方案：

把所有的版本修改为1.6.1即可（就很离谱）
implementation ‘androidx.appcompat:appcompat:1.6.1’
在gradle.properties中

android.useAndroidX=true
#android.enableJetifier=true

android.enableBuildCache=false
android.injected.testOnly=false
org.gradle.warning.mode=all
