存储更多的数据，Android的客户经理 [英] Store additional data in Android Account Manager

问题描述

我想使用android AccountManger 同步我的web服务与应用（联系人及压延标准同步）但是，的AccountManager 似乎只存储一个用户名和密码。我的网络服务有三个凭证：用户名，密码和帐号。什么是存储的第三个资料片的最佳做法？

I'd like to use the android AccountManger to sync my webservice and application (standard sync of contacts and calander) however, AccountManager only appears to store a username and password. My web service takes three credentials: a username, a password and an account. What is the best practice for storing the third piece of information?

推荐答案

由于pablisco解释的，可以使用的AccountManager的能力，通过存储任意用户数据的<一个href="http://developer.android.com/reference/android/accounts/AccountManager.html#addAccountExplicitly%28android.accounts.Account,%20java.lang.String,%20android.os.Bundle%29">addAccountExplicitly()'s用户数据包的参数：

As pablisco explained, you can use AccountManager's ability to store arbitrary user data through addAccountExplicitly()'s userData Bundle parameter:

    final Bundle extraData = new Bundle();
    extraData.putString("someKey", "stringData");
    boolean accountCreated = am.addAccountExplicitly(account, password, extraData);

稍后，例如在验证器的<一href="http://developer.android.com/reference/android/accounts/AbstractAccountAuthenticator.html#getAuthToken%28android.accounts.AccountAuthenticatorResponse,%20android.accounts.Account,%20java.lang.String,%20android.os.Bundle%29">getAuthToken()方法，你可以检索与您正在使用的帐户数据：

Later on, for example in your Authenticator's getAuthToken() method, you can retrieve the data related to the account you are working with:

    String myData = am.getUserData(account, "someKey");

不幸的是在写本书时，你只能检索字符串，所以你的数据应该存储为当您第一次建立绑定字符串。希望这可以帮助别人。

Unfortunately as of this writing you can only retrieve Strings, so your data should be stored as a String when you first build the Bundle. Hope this helps someone.
