我的android项目遇到了问题
ERROR: 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 <application> element at AndroidManifest.xml:18:5-191:19 to override.
并在gradle属性中添加了这两行
android.useAndroidX=true
android.enableJetifier=true
现在我要得到
error: cannot find symbol class ActivityCompat
我的build.gradle如下图
