[Android] AndroidX 相容問題

Run app時遇到的問題：

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:5:5–21:19 to override.

相信你可以一秒看出是個相容問題，兩秒也可以

Sol：
project目錄按下右鍵 -> Refactor -> Migrate to AndroidX

善良的Android Studio會幫你先壓一個zip，避免壞掉

好，相信這樣就解決了
讓我們繼續加油 (wave)
