若出现以下错误：

Execution failed for task ':app:processDebugMainManifest'.
> Manifest merger failed : Apps targeting Android 12 and higher are required to specify an explicit value for `android:exported` when the corresponding component has an intent filter defined. See https://developer.android.com/guide/topics/manifest/activity-element#exported for details.

可以通过该方法解决：

在 app->manifests->AndroidManifest.xml加入以下代码：
android:exported="true"
