AccessibilityService已启动，但没有收到AccessibilityEvents的软糖

问题描述

我有一个AccessibilityService的宣读任何来电通知。它做工精细与ICS及以下，而不辍符合JB。

I have a AccessibilityService that shall read out any incoming notification. It does work fine with ICS and below, but stopped working with JB.

下面是清单和code：

Below are the Manifest and the code:

<service
        android:name=".Services.InstantMessengerJb"
        android:enabled="@bool/is_post_jb"
        android:permission="android.permission.BIND_ACCESSIBILITY_SERVICE"
        tools:ignore="ExportedService" >
        <meta-data
            android:name="android.accessibilityservice"
            android:resource="@xml/accessibility_service_config" />

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

---

@Override
public void onAccessibilityEvent(AccessibilityEvent event) {
    SettingsClass.logMe(tag, "New event!");
    new AccessibilityProcessing(this, event);
}

@Override
protected void onServiceConnected() {
    if (isInit) {
        return;
    }
    SettingsClass.logMe(tag, "We are connected!");
    AccessibilityServiceInfo info = new AccessibilityServiceInfo();
    info.eventTypes = AccessibilityEvent.TYPE_NOTIFICATION_STATE_CHANGED;
    info.feedbackType = AccessibilityServiceInfo.FEEDBACK_SPOKEN;
    setServiceInfo(info);
    isInit = true;
}

正如所说它的工作在所有preJB-设备用得好好的，但是在巴顿之前启动服务（我得到了我们连），而不是一个单一事件。

As said before it does work on all preJB-Devices like a charm, however on JB the service starts (I get the "We are connected"), but not a single event is fired.

这有什么不对的code？

Is there anything wrong with the code?

推荐答案

这是我得到它的工作方式：

This is the way I got it to work:

1. 子类服务类，所以有2个版本了。

1. Subclass the service class so there are 2 versions of it.

有在res一个bools.xml文件/目录的值，也是一个在RES /值-V16目录

Have a bools.xml file in the res/values directory and also one in the res/values-v16 directory

有一个is_jelly_bean布尔值设置为true，V16和RES一个is_not_jelly_bean /值目录版本

Have a is_jelly_bean boolean set to true in v16 and a is_not_jelly_bean in the res/values directory version

在清单中有这样的事情

<service android:name=".service.MainRunningService" android:enabled="@bool/is_jelly_bean"
    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>

<service android:name=".service.MainRunningServicePreJellyBean"
    android:enabled="@bool/is_not_jelly_bean">
    <intent-filter >
        <action android:name="android.accessibilityservice.AccessibilityService" />
    </intent-filter>

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

有在res / xml目录呼叫accessibilityservice.xml一个辅助服务XML文件

Have an accessibility service xml file in the res/xml directory call accessibilityservice.xml

在它是这样的：

<accessibility-service xmlns:android="http://schemas.android.com/apk/res/android"
android:accessibilityEventTypes="typeNotificationStateChanged"
android:accessibilityFeedbackType="feedbackSpoken"
android:notificationTimeout="100"
android:description="@string/description_that_shows_on_the_accessibility_page" />
