问题描述

我最近尝试使用 AccessibilityService 读取传入的通知.我知道使用 NotificationListenerService 读取通知，但这不是我需要的(为了与较低的 android 版本兼容).我的问题是，OnServiceConnected() 永远不会被调用，即使在我的设置中，我已经为我的应用程序提供了必要的前提.这是我的代码:

I've recently tried to read incoming notifications using AccessibilityService.I know reading notifications using NotificationListenerService, but that's not what I need (for compatibility with lower android versions).My problem is, OnServiceConnected() never get called, even though in my settings, I've gave my app the neccessary premisions.Here is my code:

public class NotificationAccessibilityService extends AccessibilityService{

    protected void onServiceConnected() {
        Log.d("Tortuga", "AccessibilityService Connected");
        AccessibilityServiceInfo info = new AccessibilityServiceInfo();
        info.eventTypes = AccessibilityEvent.TYPE_NOTIFICATION_STATE_CHANGED;
        info.feedbackType = AccessibilityServiceInfo.FEEDBACK_ALL_MASK;
        info.notificationTimeout = 100;
        setServiceInfo(info);
    }

    @Override
    public void onAccessibilityEvent(AccessibilityEvent e) {
        Log.d("Tortuga","FML");
        if (e.getEventType() == AccessibilityEvent.TYPE_NOTIFICATION_STATE_CHANGED) {
            Log.d("Tortuga","Recieved event");
            Parcelable data = e.getParcelableData();
            if (data instanceof Notification) {
                Log.d("Tortuga","Recieved notification");
                Notification notification = (Notification) data;
                Log.d("Tortuga","ticker: " + notification.tickerText);
                Log.d("Tortuga","icon: " + notification.icon);
                Log.d("Tortuga", "notification: "+ e.getText());
            }
        }
    }

    @Override
    public void onInterrupt() {
        // TODO Auto-generated method stub
    }
}

还有我的 XML:

AndroidManifest.xml

<service
            android:name="com.tortuga.shutapp.NotificationAccessibilityService"
            android:label="@string/app_name"
            android:permission="android.permission.BIND_ACCESSIBILITY_SERVICE" >
            <intent-filter>
                <action android:name="android.accessibilityservice.AccessibilityService" />
            </intent-filter>

            <meta-data
                android:name="android.accessibilityservice"
                android:resource="@xml/accessibilityservice" />
        </service>

xmlaccessibilityservice.xml

<?xml version="1.0" encoding="utf-8"?>
<accessibility-service xmlns:android="http://schemas.android.com/apk/res/android"
    android:accessibilityEventTypes="typeNotificationStateChanged"
    android:accessibilityFeedbackType="feedbackSpoken"
    android:notificationTimeout="100" />

请帮忙，我迷路了.我目前在 Nexus 5 上运行.谢谢！
