我该如何找回登录谷歌帐户Android手机？ [英] How do I retrieve the logged in Google account on android phones?

问题描述

我开发一个Android应用程序，我需要找回在手机上使用的谷歌帐户。我想这样做的C2DM，但我不想要求用户在他/她的谷歌电子邮件帐户进入，如果他们已经登录。有没有办法做到这一点？

I am developing an Android application and I need to retrieve the Google account used on the phone. I want to do this for the C2DM, but I don't want to ask the user to enter in his/her Google email account if they are already logged in. Is there any way to do it?

推荐答案

这样的事情应该工作：

AccountManager manager = (AccountManager) getSystemService(ACCOUNT_SERVICE);
Account[] list = manager.getAccounts();
String gmail = null;

for(Account account: list)
{
    if(account.type.equalsIgnoreCase("com.google"))
    {
        gmail = account.name;
        break;
    }
}

和您将需要下列权限在你的清单：

And you will need the following permission in your manifest:

<uses-permission android:name="android.permission.GET_ACCOUNTS"></uses-permission>

我写这从内存中，因此它可能需要一些调整。显然，这是可能的，现在注册没有电子邮件地址，所以也许做对数据的一些regexing，以确保它实际上是一个电子邮件地址（确保它包含@gmail或@googlemail）

I wrote this from memory so it may need a little tweaking. Apparently it's possible to register now without an email address, so maybe do some regexing on the data to ensure it's actually an email address (ensure it contains @gmail or @googlemail)
