所以我正在创建一个请求用户谷歌帐户权限的应用。我用我的测试，所以我给了它许可，然后删除它，看它是否会再次要求它。它仍然使用它获得的令牌，所以我从手机中删除了应用程序并重新安装它。我没有更改任何代码，现在突然它只显示帐户页面（选择哪个帐户），然后一旦我按下确定，没有任何显示给它许可。在我的运行控制台中，我得到以下内容：
$ adb push C:\Users\James Singleton\AndroidStudioProjects\ChffrAPI\app\build\outputs\apk\app-debug.apk /data/local/tmp/com.example.jamessingleton.chffrapi
$ adb shell pm install -r "/data/local/tmp/com.example.jamessingleton.chffrapi"
