onAccessibilityEvent（AccessibilityEvent事件）不拦截通知 [英] onAccessibilityEvent(AccessibilityEvent event) not intercepting notification

问题描述

在我的应用程序，我要赶在新收到的电子邮件的按摩通知并说明该事件的屏幕上播放视频。 我使用了 onAccessibilityEvent（AccessibilityEvent事件）听生成的通知。 我也用下面的$ C $下初始化我AccessibilityService：

In my application I have to catch the new incoming email massage notification and play a video on the screen which describe the event. I'm using the onAccessibilityEvent(AccessibilityEvent event) to listen to the generated notification. I also use the following code for init my AccessibilityService:

    AccessibilityServiceInfo localAccessibilityServiceInfo = new AccessibilityServiceInfo();
    localAccessibilityServiceInfo.eventTypes = AccessibilityEvent.TYPES_ALL_MASK; // AccessibilityEvent.TYPE_NOTIFICATION_STATE_CHANGED;
    localAccessibilityServiceInfo.notificationTimeout = EVENT_NOTIFICATION_TIMEOUT_MILLIS;
    localAccessibilityServiceInfo.feedbackType = AccessibilityServiceInfo.FEEDBACK_AUDIBLE; // AccessibilityServiceInfo.FEEDBACK_VISUAL;
    localAccessibilityServiceInfo.flags &= AccessibilityServiceInfo.DEFAULT;
    setServiceInfo(localAccessibilityServiceInfo);

但事件没有到达。 如何可以解决？ 谢谢， 的Eyal。

but event never arrived. How it can be solved? Thanks, Eyal.

推荐答案

我有类似的情况，这部作品在我的应用程序：

I have a similar situation, this works in my application:

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

public class NotificationAccessibilityService 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);

    }
}

在我的清单：

And in my manifest:

<service android:name=".accessibility.NotificationAccessibilityService" android:label="@string/app_name" android:enabled="true" android:exported="false">
        <intent-filter>
            <action android:name="android.accessibilityservice.AccessibilityService" />
        </intent-filter>

</service>
