android - onAccessibilityEvent(AccessibilityEvent event) 不拦截通知

Question

在我的应用程序中，我必须捕获新的传入电子邮件消息通知并在屏幕上播放描述该事件的视频。我正在使用 onAccessibilityEvent(AccessibilityEvent event) 来收听生成的通知。我还使用以下代码来初始化我的 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);

但事件从未到来。如何解决？谢谢，埃亚尔。

我有类似的情况，这在我的应用程序中有效:

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 list 中:

<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>
