我已经安装了Glassfish 4并尝试创建一些JMS资源来跟踪学习JMS的教程,但这是不可能的.在Web界面上,它始终显示文本"java.lang.RuntimeException",并在日志控制台上显示堆栈跟踪.抛出此异常总是我在"JMS目标资源"页面或连接工厂的页面中按下"新建..."链接.这是堆栈跟踪:

<receiver android:name="your.package.name.CatchChangesReceiver"
android:priority="1000" >
<intent-filter>
<action android:name="android.intent.action.PROVIDER_CHANGED" />
<data android:scheme="content" />
<data android:host="com.android.calendar" />
</intent-filter>
</receiver>
然后创建一个扩展广播接收器的简单类：
public class CatchChangesReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
// add processing here with some query to content provider
// in my project I use this selection for getting events:
final String SELECTION = CalendarContract.Events.CALENDAR_ID + "="
+ calendarId + " AND " + "("
+ CalendarContract.Events.DIRTY + "=" + 1 + " OR "
+ CalendarContract.Events.DELETED …我开发了一个基于辅助服务的 Android 应用程序。但我有一个问题，我在互联网上找不到任何帮助。当我在任何设备上安装该应用程序时，显然它不会开始工作，直到：
\n\n问题有点复杂：\n启用辅助功能服务后，我可以在辅助功能设置屏幕中看到该服务显示“已启用”。事实上，该应用程序正在运行。但是如果我进入该服务，顶部和右侧有一个开关显示为“关闭”。为什么？服务已启用并正在运行没有任何意义，并且开关显示为“关闭”。
\n\n我尝试过使用其他服务作为内置的 Talkback。当我打开开关，返回辅助功能设置屏幕，然后再次进入对讲服务时，开关保持打开状态。为什么我的服务无法正常工作？
\n\n我再次解释说，虽然激活开关不能正常工作，但我的应用程序确实可以工作，唯一的问题是该开关，当我的服务已经打开时，它会让用户感到困惑，显示关闭。
\n\n有什么原因会导致这种情况发生吗？也许我错过了诸如告诉系统服务何时启用之类的事情？
\n\n我的服务代码没有什么异常，与任何其他辅助服务类似，除了事件发生时的自定义操作之外。
\n\n以下是应用程序的清单 XML 文件：
