adb 获取 mUsageStatsManager.getAppStandbyBucket()

`mUsageStatsManager.getAppStandbyBucket()`是一个Java API，它用于获取指定应用程序的待机桶号。待机桶是Android系统中用于管理应用程序待机状态的一种机制，它将应用程序分成几个档次（0~5），每个档次都有不同的待机策略，例如限制网络访问、禁止后台更新等。使用ADB获取指定应用程序的待机桶号的命令如下：

adb shell dumpsys deviceidle | grep [package name]

其中 `[package name]` 是要获取待机桶号的应用程序的包名，命令会返回包含应用程序待机桶号的信息，例如：
