Android自动备份：传输被拒绝的包

我正在尝试测试。我使用的是7.1设备，应用程序清单包含：

android:fullBackupOnly=“true”

。当我发出

adb shell bmgr backupnow

命令（对于SO post，我用占位符替换了我的包名）时，我得到了一个失败的结果：

Running backup for 1 requested packages.
Package @pm@ with result: Success
Package <package> with result: Transport rejected package
Backup finished with result: Success

查看拒收案例中的Logcat，我看到以下内容：

超额

如果在logcat中看到以下消息：

I/PFTBT:包的传输被拒绝备份，跳过

---或---

I/PFTBT:超过包裹的运输配额：包裹

你的应用程序 超出配额，已被禁止备份此服务器上的数据 装置。要解除禁令，请在出厂时重置设备或更改 备份帐户

---

我得到了同样的错误，最终找到了解决方案：

build.gradle

中的

targetsklevel

必须设置为23或更高

---

如果

targetSdkLevel

设置为例如21，则项目将在模拟器中编译并运行良好。但要使用Google Play服务作为备份目的地（我想我们大多数人都在使用它），它必须至少是23。

我看到了，但文档表明每个应用的配额应该是25MB，我应该远远低于这个数字。如果你在模拟器中安装你的应用，那么你可以使用：adb shell；苏,；ls-la/sdcard/Android/data//文件；ls-la/数据/数据/；我也有同样的问题，案例是“I/PFTBT:Transport拒绝备份软件包，跳过”，我甚至尝试了新安装的应用程序，删除了所有数据，但仍然存在。尝试为传输设置详细的道具，但我找不到拒绝的原因：（@PetrNalevka对我来说是相同的问题任何更新相同的问题在api级别29中至少在某些设备上仍然出现相同的问题。在我的三星SM-T585平板电脑上，我只能备份我的应用程序一次，所有其他时间都会看到“传输拒绝备份…”。
