BackupManagerService:无法完成还原
BackupManagerService: Unable to finalize restore
应用程序更新后,我检查了一下,似乎所有用户的数据都被莫名其妙地删除了。
检查 logcat 显示了一些可疑行:

04-11 15:06:27.225 24281-26232/? D/BackupManagerService: Restore complete, killing host process of com.my.package
发生此问题时,应用的 AndroidManifest
有:
android:allowBackup="true"
出于测试目的,我生成了一个新的 apk
android:allowBackup="false"
改成false后就没有了。
什么会导致这个问题?
关键是这一行:
Restore manifest signatures do not match installed application.
当您在发布模式下备份而在调试模式下恢复时可能会发生这种情况,反之亦然。 BackupManagerService#restoreFinished()
.
抛出异常
要手动删除备份,请执行 this 步骤。
