我正在使用此代码创建帐户。但它会引发安全异常。并且该帐户不会被创建。

public static Account getSyncAccount(Context context) {
    AccountManager accountManager =(AccountManager) context.getSystemService(Context.ACCOUNT_SERVICE);
    Account newAccount = new Account(context.getString(R.string.app_name), context.getString(R.string.sync_account_type));

    if ( null == accountManager.getPassword(newAccount) ) {
        if (!accountManager.addAccountExplicitly(newAccount, "", null))
            return null;                     
       onAccountCreated(newAccount, context);
    }
    return newAccount;
}

logcat 中的错误如下所示：

AndroidManifest 看起来像这样：

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.demo" >

<application

        <meta-data android:name="android.content.SyncAdapter"
            android:resource="@xml/syncadapter" />
    </service>
</application>

我在网上查了一下，但找不到解决方案。我究竟做错了什么？
