如何让AccountManager创建的账户自动触发SyncAdapter同步？

我已经在手机的账户管理界面，通过AccountManager创建了和我的应用关联的账户，了解到需要借助SyncAdapter来实现用该账户启动会话的功能。目前我已经在Manifest中配置了Provider和Service，也编写了SyncAdapterService类及SyncAdapter实现类，具体代码如下：

Manifest配置代码 #

<provider 
    android:name="com.example.pargibay.androidphprpcxml.StubProvider" 
    android:authorities="com.example.pargibay.androidphprpcxml.provider" 
    android:exported="false" /> 
<service 
    android:name=".SyncAdapterService" 
    android:exported="true">
    <intent-filter>
        <action android:name="android.content.SyncAdapter" />
    </intent-filter>
    <meta-data 
        android:name="android.content.SyncAdapter" 
        android:resource="@xml/sync_adapter" />
</service>

SyncAdapterService类代码 #

public class SyncAdapterService extends Service { 
    private static SyncAdapter sSyncAdapter = null; 
    private static final Object sSyncAdapterLock = new Object(); 

    @Override 
    public void onCreate() { 
        Log.d("SyncStarted","SyncService started"); 
        synchronized (sSyncAdapterLock) { 
            if (sSyncAdapter == null) { 
                try { 
                    sSyncAdapter = new SyncAdapter(getApplicationContext(), true); 
                } catch (MalformedURLException e) { 
                    e.printStackTrace(); 
                } 
                Log.d("SyncStoped","SyncService stoped"); 
            } 
        } 
    } 

    @Nullable 
    @Override 
    public IBinder onBind(Intent intent) { 
        return sSyncAdapter.getSyncAdapterBinder(); 
    } 
}

SyncAdapter实现类代码 #

public class SyncAdapter extends AbstractThreadedSyncAdapter { 
    public SyncAdapter(Context context, boolean autoInitialize) throws MalformedURLException { 
        super(context, autoInitialize); 
    } 

    @Override 
    public void onPerformSync(Account account, Bundle extras, String authority, ContentProviderClient provider, SyncResult syncResult) { 
        // 这里还未实现同步逻辑
    } 
}

我已经参考相关教程完成了AccountManager创建账户的部分，现在想了解如何让这个已添加的账户实现自动同步。另外，我希望能实现这样的效果：可以在应用内查看已添加的账户，并且能够手动触发同步操作。
