GoogleApiClient连接失败：ConnectionResult{statusCode=SIGN_IN_REQUIRED，

Question

我正在尝试将Google Drive集成到我的应用程序中，但成功率很低。使用Quick Start存储库中的代码，每次选择用户帐户登录时，我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}

我已经按照以下链接的指示操作：

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

同时我还观看了以下视频：

我也查阅了许多关于Stack Overflow的问题和答案，但仍然不知道我做错了什么。

manifest.xml:

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

代码：

    if (mGoogleApiClient == null) {
        // Create the API client and bind it to an instance variable.

你在Google API控制台中注册了开发/发布密钥吗？ - Cheok Yan Cheng

所有创建和注册密钥的步骤都已按照要求完成。 - lightkeeper

@lightkeeper在开发者控制台中使用您的软件包和SHA密钥创建AuthKey，就可以开始了... - user3809705

请注意，Studio的Instant Run不会创建已签名APK文件......除非您将签名信息放置在应用程序的build.gradle文件中。 - RudyF

Answer 1

根据文档 - SIGN_IN_REQUIRED

客户端尝试连接服务，但用户未登录。客户端可以选择继续使用API而不进行登录。或者，如果hasResolution()返回true，则客户端可以调用startResolutionForResult(Activity, int)提示用户进行登录。在登录活动以RESULT_OK返回后，进一步的尝试应该成功。

您也可以查看@Cheok的问题，这是一个SO post，建议按要求正确添加您的SHA-1和包名，并在项目凭据全部设置后启用API。

希望这些信息能够帮助到您。

我按照所有步骤创建了密钥并在API控制台中注册了它。API在控制台上显示为活动状态。这就是我卡住的原因。 - lightkeeper

Answer 2

我遇到了类似的问题，后来解决了，原因是每个 APK 构建都由相同的密钥库签名，这与我在“获取 Android 证书并注册应用程序”时使用的密钥库相同，详情请参见此处。

在使用 Studio 时，我按照“配置构建过程以自动签名您的 APK”的步骤执行了“自动签名”，详情请参见此处。显然，要使用与注册应用程序时使用的密钥库相同的密钥库。
