android-5.0-lollipop - BackupManagerService恢复超时导致强制停止

Question

从昨天开始，我的 Nexus 5 开始运行 Lollipop，我正在处理的应用程序停止运行，没有任何崩溃。

每次退出时，设备都会记录以下内容:

11-20 00:23:32.679: I/ActivityManager(723): START u0 {flg=0x14008000 cmp=com.mycompany.android/.app.LoginActivity} from uid 10549 on display 0

11-20 00:26:50.027: I/BackupManagerService(723): Next restore package: RestoreDescription{com.mycompany.android : KEY_VALUE}
11-20 00:26:50.028: V/BackupManagerService(723): Package com.mycompany.android restore version [0] is compatible with installed version [0]
11-20 00:26:50.028: W/BackupManagerService(723): Signature mismatch restoring com.mycompany.android
11-20 00:26:50.236: D/BackupManagerService(723): Received broadcast Intent { act=android.intent.action.PACKAGE_ADDED dat=package:com.mycompany.android flg=0x4000010 (has extras) }
11-20 00:26:50.240: D/BackupManagerService(723): Now staging backup of com.mycompany.android

听起来系统决定强制停止我的应用程序，因为恢复超时。
当应用程序正确签名时也会发生这种情况。

BackupManager 相关的实现在 4.4.2 之前运行良好。

我目前正在检查是否不调用任何 BackupManager API 可以解决这个意外/无声的强制停止。现在看起来还可以。

有什么建议吗？

使用 Android Studio 中的 gradle，您可以为您的调试构建创建一个带有 AndroidManifest.xml 文件的调试目录，以禁用 BackupManager:

    <?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools">

    <application
        android:allowBackup="false"
        tools:replace="android:allowBackup">

    </application>
</manifest>
