manifest merger failed : android:exported needs to be explicitly specified for <activity>. 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.

manifest合并失败：需要明确指定android:exported <activity>。针对Android 12及更高版本的应用程序，在相应组件定义了意图过滤器时，需要指定`android:exported`的明确值。有关详细信息，请参见https://developer.android.com/guide/topics/manifest/activity-element#exported。
