android – GoogleApiClient连接失败：ConnectionResult {statusCode = SIGN_IN_REQUIRED,

我正在尝试将Google云端硬盘集成到我的应用程序中,但收效甚微.使用快速启动存储库中的代码,每次选择登录用户帐户时,都会收到以下错误消息：

I/DriveDemo: Googleapiclient connection Failed: ConnectionResult{statusCode=SIGN_IN_required,resolution=PendingIntent{867e070: android.os.BinderProxy@13cdfe9},message=null}

我按照以下网址的指示：

> https://developers.google.com/drive/android/get-started
> https://github.com/googledrive/android-quickstart

并按照视频：

我也看了很多Stack Overflow问题和答案,不知道我做错了什么.

manifest.xml文件：

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.lightkeeper54.chuck.drivedemo">

解决方法

基于文档 – SIGN_IN_REQUIRED

The client attempted to connect to the service but the user is not signed in. The client may choose to continue without using the API. Alternately,if 07001 returns true the client may call 07002 to prompt the user to sign in. After the sign in activity returns with 07003 further attempts should succeed.

您也可以查看@ Cheok的问题,SO post,建议按要求正确添加SHA-1和包名称,并在项目凭据全部设置后启用API.
