SmsManager 在发送每条短信之间有延迟

Question

早上好，谢谢，对不起我的英语！

我在 android 应用程序中工作，我希望该应用程序使用 SmsManager 发送大量短信。很好，但是问题出在我尝试在发送每条短信之间实现任何类型的中间件时。我也尝试在 for 和 asynctask 中使用线程，但应用程序也进入休眠状态，我需要应用程序在我发送短信时不会阻塞。

我读取了外部（应用程序目录内）文件的编号，然后将该数据放入哈希表中，然后执行 for 循环以调用 SmsManager 函数 sendTextMessage。

Answer 1

public final void startForeground(int id, Notification notification) {
        try {
            mActivityManager.setServiceForeground(
                    new ComponentName(this, mClassName), mToken, id,
                    notification, 0);
        } catch (RemoteException ex) {
        }
    }

foregroundService 在service里面处理

Answer 2

最后，我设法解决了它。我将 Handler 和 Thread 与 progressBar 一起使用。

我把代码放在这里，希望对你有帮助。
