BlackBerry Java项目中,我尝试添加一个功能,以确保应用程序可以在后台运行。它在BB的模拟器上正常运行,但在设备中运行时失败并出现错误。

Error: Module 'My_Project' must be signed with the RIM Runtime Code Signing Key (RTT)

问题出现在以下代码中:

    private ApplicationIndicatorRegistry reg;
    private ApplicationIndicator indicator;
    public static  ApplicationIndicator AppIndi;
    public AfmobiMobile() {
        testMobile = this;

        reg=ApplicationIndicatorRegistry.getInstance();
        EncodedImage img=EncodedImage.getEncodedImageResource("ic2.png");
        ApplicationIcon icon =new ApplicationIcon(img);
        indicator=reg.register(icon, false, true);
        AppIndi=reg.getApplicationIndicator();
}

然后,此卷的所有打开句柄都将无效。
