无法让我的帐户显示在 Android 帐户中...任何人都可以看一下吗？

Question

很多代码...我从Android的官方示例代码中得到了这个， SampleSyncAdapter

无论如何，这是代码。我没有包含同步类，我只是想让帐户显示出来并能够暂时创建。

    }
}

}

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();
    }
}

Manifest 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">

服务中引用的 xml 文件在这里：

<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...但是我'我变得非常绝望地试图为此找到结果。据我了解，这应该可以正常工作，但是当我添加帐户时，它会超时/崩溃，或者只是不将我的应用程序的帐户显示为添加选项。我已经在模拟器和我的实际 Android 手机中尝试过此操作，但都不起作用。 Logcat 失败时不会产生任何错误。如果有人有这方面的经验并且可以提供一些示例代码/见解来解释为什么我的代码不起作用，我真的很感激......非常感谢！

我没有看到您的列界面文件。它定义您的自定义 MIME_PROFILE 以及您的联系人数据存储在数据表中的哪些列。
