FC try to start my Android AccessibilityService
===

I am using Jelly Bean v16 API, follow the Guide here: <a href="http://developer.android.com/training/accessibility/service.html">Developing an Accessibility Service</a>

I haven't start to add anything, just a blank service, but it crash instantly after I try to start the service.

here is the code, which part I did wrong?

AndroidManifest.xml

    <manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.firstapp.service"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk
        android:minSdkVersion="16"
        android:targetSdkVersion="15" />

    <application
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <service android:name=".MyAccessibilityService" >
            <intent-filter>
                <action android:name="android.accessibilityservice.AccessibilityService" />
            </intent-filter>
        </service>
    </application>

</manifest>


MyAccessibilityService.java


    package com.example.android.apis.accessibility;

    import android.accessibilityservice.AccessibilityService;
    import android.view.accessibility.AccessibilityEvent;
    
    public class MyAccessibilityService extends AccessibilityService {
        @Override
        public void onAccessibilityEvent(AccessibilityEvent event) {
        }
    
        @Override
        public void onInterrupt() {
        }
    
    }
