Android应用程式在addAccountExplicitly(帐户，密码，空值)时当机； [英] Android app crashes on addAccountExplicitly(account, password, null);

问题描述

在成功进行基本身份验证之后，我想添加一个帐户以供以后使用.当我尝试使用以下代码创建此帐户时:

After a successful basic authentication I want to add an account for later use. When I tried to create this account using the following code:

AccountManager accountManager = AccountManager.get(getBaseContext());
final Account basicAccount = new Account(mEmail, "com.example");
accountManager.addAccountExplicitly(basicAccount, mPassword, null);

调用addAccountExplicitly(...)时，应用程序崩溃并出现以下错误:

When addAccountExplicitly(...) is called the app crashes with the following error:

问题:

1. 我确定我的AccountType与我的authenticator.xml中指定的相同.为什么我的代码崩溃?
2. 使用基本身份验证甚至可以使用AccountManager和Account吗?我还没有找到一个很好的例子(它们都使用令牌...)
3. 我的想法是将此帐户用于多个应用程序.使用服务进行身份验证(是否有意图)是否被视为最佳做法?有什么好的教程吗?

谢谢，谢谢

推荐答案

1)崩溃的原因是因为AndroidManifest.xml中缺少以下代码段.

1) Reason for crash was because the following snippet was missing in AndroidManifest.xml.

<service android:name="com.example.accounts.GenericAccountService">
    <intent-filter>
         <action android:name="android.accounts.AccountAuthenticator" />
    </intent-filter>
    <meta-data android:name="android.accounts.AccountAuthenticator" android:resource="@xml/authenticator" />
</service>

2)绝对有可能，即使仍然缺少最佳实践示例.

2) It is absolutely possible, even though best practice example is still missing.

3)不知道.但是...

3) No idea. Yet...
