清单合并失败：需要为元素显式指定 android:exported <service#com.marianhello.bgloc.sync.authenticatorservice></service#com.marianhello.bgloc.sync.authenticatorservice>

Question

我正在尝试生成签名版本，但在 android studio Manifest merger failed: android:exported needs to be explicitly specified for element <service#com.marianhello.bgloc.sync.AuthenticatorService>. Apps targeting Android 12 and higher are required to specify an explicit value for when the corresponding component has an intent filter defined. See https://developer.android.com/guide/topics/manifest/activity-element#exported for details.

Answer 1

方法一、将Android API降到31以下版本，Android 12要求显式定义android:exported。

方法二、如果依赖库有问题，建议升级到最新的依赖。 如果最新的依赖还没有解决这个问题，可以直接点击报错的AndroidManifest.xml，直接编辑manifest文件，手动添加android:exported属性。 添加完成后，重建项目。

注意：第二种编辑 AndroidManifest.xml 的方法只是让项目运行的一种特殊方式。 每次重新启动项目时都需要进行此修改。
