嗯，我想实现这个服务之一，我用code从这里：的 http://developer.android.com/training/accessibility/service.html#create 但我不能启用该服务，因为我没有看到它在系统设置。谁能帮助我？

解决方案

好吧，我留下了一些重要的东西在的Andr​​oidManifest.xml ，所以现在它的工作完美。这里是新的清单

 ＆LT;服务        机器人：NotificationServiceNAME =        机器人：权限=android.permission.BIND_ACCESSIBILITY_SERVICE        类=。NotificationService        机器人：启用=真        机器人：出口=假＆GT;        ＆所述;意图滤光器＆gt;            ＆lt;作用                机器人：NotificationServiceNAME =                NotificationService：机器人值= /＆GT;        ＆所述; /意图滤光器＆gt;        ＆所述;意图滤光器＆gt;            ＆lt;作用机器人：名字=android.accessibilityservice.AccessibilityService/＆GT;        ＆所述; /意图滤光器＆gt;    ＆LT; /服务＆GT; 

Well I'm trying to implement one of this services, I'm using the code from here: http://developer.android.com/training/accessibility/service.html#create but I can't enable the service since I don't see it in system settings. Could anyone help me out?

Manifest:

<service android:name=".MyAccessibilityService" >
        <intent-filter>
            <action android:name="android.accessibilityservice.AccessibilityService" />
        </intent-filter>
    </service>

MyAccessibilityService.java

import android.accessibilityservice.AccessibilityService;
import android.accessibilityservice.AccessibilityServiceInfo;
import android.util.Log;
import android.view.accessibility.AccessibilityEvent;
import android.widget.Toast;

public class MyAccessibilityService extends AccessibilityService
{
public static final String TAG = "volumeMaster";

@Override
public void onAccessibilityEvent(AccessibilityEvent event)
{
    Log.v(TAG, "***** onAccessibilityEvent");
    Toast.makeText(getApplicationContext(), "Got event from: " + event.getPackageName(), Toast.LENGTH_LONG).show();
}

@Override
public void onInterrupt()
{
    Log.v(TAG, "***** onInterrupt");
}

@Override
public void onServiceConnected()
{
    Log.v(TAG, "***** onServiceConnected");

    AccessibilityServiceInfo info = new AccessibilityServiceInfo();
    info.eventTypes = AccessibilityEvent.TYPE_NOTIFICATION_STATE_CHANGED;
    info.notificationTimeout = 100;
    info.feedbackType = AccessibilityEvent.TYPES_ALL_MASK;
    setServiceInfo(info);

}
}

Well I left some important things in the AndroidManifest.xml, so now its working perfectly. Here's the new manifest

    <service
        android:name=".NotificationService"
        android:permission="android.permission.BIND_ACCESSIBILITY_SERVICE"
        class=".NotificationService"
        android:enabled="true"
        android:exported="false" >
        <intent-filter>
            <action
                android:name=".NotificationService"
                android:value=".NotificationService" />
        </intent-filter>
        <intent-filter>
            <action android:name="android.accessibilityservice.AccessibilityService" />
        </intent-filter>

    </service>
