导入支持库之后出现java.lang.RuntimeException
不知为什么这次创建了一个moudle导入支持库之后出现了Manifest merger failed : Attribute application@appComponentFactory value=(android.support.v4.app.CoreComponentFactory) from [com.android.support:support-compat:28.0.0] AndroidManifest.xml:22:18-91
is also present at [androidx.core:core:1.0.0] AndroidManifest.xml:22:18-86 value=(androidx.core.app.CoreComponentFactory).
Suggestion: add 'tools:replace="android:appComponentFactory"' to
仔细打开后出现了Execute taskAction
详细的错误
java.lang.RuntimeException: Manifest merger failed : Attribute application@appComponentFactory value=(android.support.v4.app.CoreComponentFactory) from [com.android.support:support-compat:28.0.0] AndroidManifest.xml:22:18-91
is also present at [androidx.core:core:1.0.0] AndroidManifest.xml:22:18-86 value=(androidx.core.app.CoreComponentFactory).
Suggestion: add 'tools:replace="android:appComponentFactory"' to element at AndroidManifest.xml:5:5-19:19 to override.

等等
重点在这里，解决办法就是在 gradle.properties文件里面加上
android.useAndroidX=true
android.enableJetifier=true然后在同步一下就可以了
还有就是可能导入的库版本过高，这个时候可以试一试降低一下导入的版本，在这里我就是降低的版本解决的问题
