Question

我想使用Push注册表在指定时间启动midlet。当我运行应用程序时，即使超过时间，midlet也不会启动..

public void startApp（）{

    System.out.println( "AlarmMIDlet: startApp" );

    try {
        Date    now = new Date();
        long    previous;
                    String cn = this.getClass().getName();
                    System.out.println("Class name : "+cn);
        previous    = PushRegistry.registerAlarm( "hello.AlarmMIDlet", now.getTime() + 600 );

        System.out.println( "AlarmMIDlet: time of previous alarm: " + previous );
    } catch ( java.lang.ClassNotFoundException cnf ) {
        System.out.println( "AlarmMIDlet: Class not Found" );
    } catch ( javax.microedition.io.ConnectionNotFoundException connnf ) {
        System.out.println( "AlarmMIDlet: Connection Not Found" );
    }

    System.out.println( "AlarmMIDlet: startApp: return" );

    notifyDestroyed();
}

任何人都遇到过类似的问题？如何解决这个问题？

公平地说，我从未使用过PushRegistry，但从我读过的内容来看，你需要在middlet destroyApp（）上安排时间报警。看看这篇文章，向下滚动Registering a Timer Alarm

如何在特定时间自动启动midlet？
