如何打开google drive项目（android quickstart）

我想打开google drive的一个示例。但我做不到

当我单击用户Google Id时，错误消息是

12-05 19:07:30.511 21192-21192/com.google.android.gms.drive.sample.quickstart I/drive-quickstart: GoogleApiClient connection failed: ConnectionResult{statusCode=SIGN_IN_REQUIRED, resolution=PendingIntent{2397a78c: android.os.BinderProxy@2b9c8df4}, message=null}
12-05 19:07:30.881 21192-21192/com.google.android.gms.drive.sample.quickstart V/ActivityThread: updateVisibility : ActivityRecord{20df1792 token=android.os.BinderProxy@2b33ccce {com.google.android.gms.drive.sample.quickstart/com.google.android.gms.drive.sample.quickstart.MainActivity}} show : true

我在GoogleDeveloper控制台中创建了我的客户端ID和API密钥

如何在

AndroidManifest.xml

文件中配置它

AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?>

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.google.android.gms.drive.sample.quickstart"

您不应该公开显示API密钥。感谢您的评论。您是否可以尝试在onActivityResult上显示的switch语句中添加请求\代码\解析的案例。在这种情况下，请尝试再次调用mgoogleapclient.connect（）。我希望这能奏效。
