问题使用android.accounts验证器 [英] Problem using android.accounts Authenticator
问题描述
我是新来的android.accounts的API，现在我试图做一些与他们，但出现得体哑问题...结果
I`ve创建一个Authenticator我的应用程序，但还没有实现抽象方法。它的成功的图标出现在系统中添加帐户窗口，我知道，当我点击它，在身份验证方法addAccount将被调用。
I'm new to the android.accounts apis, and now I'm trying to do something with them but a seemly dummy problem occurs...
I`ve created an Authenticator for my app but did not yet implement the abstract methods. The icon of it successfully appears in the system Add a Account window, and I know that when I click it, the method addAccount in the Authenticator will be invoked.
现在我希望做这个方法有些简单的事情，写codeS如下：
Now I wish to do some simple thing in this method, and write codes below:
@Override
public Bundle addAccount(AccountAuthenticatorResponse response,
String accountType, String authTokenType, String[] requiredFeatures,
Bundle options) {
Log.d(LOG_TAG, "RRAuthenticator add account... ");
String accountName = "example@example.com";
Account account = new Account(accountName, accountType);
String password = "example_password";
AccountManager manager = AccountManager.get(context);
manager.addAccountExplicitly(account, password, null);
Bundle bundle = new Bundle();
bundle.putString(AccountManager.KEY_ACCOUNT_NAME, accountName);
bundle.putString(AccountManager.KEY_ACCOUNT_TYPE, accountType);
bundle.putString(AccountManager.KEY_AUTHTOKEN, "example_authtoken");
return bundle;
}
我见过SampleSyncAdapter的演示，使喜欢它的动作。但我练直接添加的帐户使用这些API。
但系统的崩溃行 manager.addAccountExplicitly（帐号，密码为空）;
这有什么错呢？
I've seen the demo of SampleSyncAdapter, and make moves like it. But I practice using these APIs by directly adding an account.
But system crashed by the line manager.addAccountExplicitly(account, password, null);
What's wrong with it?
后来补充：
异常的系统进程。系统将崩溃。
NullPointerException异常被抛出的AccountManager。
看来addAccountExplicitly方法的问题，因为我评论这一说法没有崩溃发生。
Added later: Exception in system process. System will crash. NullPointerException throw by AccountManager. It seems the problem of the addAccountExplicitly method, as I comment this statement no crash happen.
推荐答案
我的工作了。
事实证明，它在Android 2.0的一个bug。结果
如果您添加帐户到的AccountManager，你的必须的也提供了SynAdapter的帐号，在Android 2.0平台下。但事情都是正确的Android下的2.1及以上。
It turns out that it's a bug in Android 2.0.
If you add an account to the AccountManager, you must also provide a SynAdapter to the account, under the Android 2.0 platform. But things are all right under Android 2.1 and above.
