无法让我的帐户在Android帐户中显示......任何人都可以看看吗？

Question

很多代码...我从Android的官方示例代码中获得了这个，SampleSyncAdapter

反正这里是代码。我没有包含同步类，我只想让帐号出现并能够立即创建。

AuthenticatorService类：

package com.tagapp.android; 

import android.app.Service; 
import android.content.Intent; 
import android.os.IBinder; 

public class AccountAuthenticatorService extends Service { 

    private AccountAuthenticator mAuthenticator; 

    @Override 
    public void onCreate() { 
     mAuthenticator = new AccountAuthenticator(this); 
    } 

    @Override 
    public IBinder onBind(Intent intent) { 
     return mAuthenticator.getIBinder(); 
    } 
} 

清单包括以下内容：

<service android:name=".authenticator.AccountAuthenticatorService" 
      android:exported="true"> 
      <intent-filter> 
       <action android:name="android.accounts.AccountAuthenticator" /> 
      </intent-filter> 
      <meta-data android:name="android.accounts.AccountAuthenticator" 
       android:resource="@xml/authenticator"/> 
     </service> 

和...

<activity android:name=".AuthenticatorActivity" 
     android:label="Sync Tag Account!" 
     android:theme="@android:style/Theme.Dialog" 
     android:excludeFromRecents="true"> 

在服务中引用的XML文件是在这里：

<account-authenticator xmlns:android="http://schemas.android.com/apk/res/android" 
    android:accountType="com.tagapp.android" 
    android:icon="@drawable/taglogo" 
    android:smallIcon="@drawable/launchicon" 
    android:label="Tag"/> 

我知道这是很多代码......但我已经变得非常绝望，试图为此找到结果。据我所知，这应该工作得很好，但是当我去添加一个帐户它超时/崩溃，或者只是不显示我的应用程序的帐户作为一个选项添加。我已经在模拟器和我的实际Android手机上尝试了这两种方法，但都没有成功。 Logcat出现故障时不会产生错误。如果有人有这方面的经验，并可以提供一些示例代码/洞察力，为什么我的代码不工作，我真的很感激它......非常感谢！

我没有看到你的列接口文件。它定义了您的自定义MIME_PROFILE以及您的联系人数据存储在数据表中的哪些列。
