android 中每秒钟的 Http 请求

Question

我需要 post 每秒钟（实际上是 500 毫秒）一个 http 请求，另一方面，我必须每秒钟从 ble 接收数据，我已经尝试过倒计时计时器、服务、JobIntentService、 bt 所有这些都以 OutOfMemory Exception 结束。我不能使用 workManager 因为 WM 的最小间隔是 15 分钟。 有什么建议或指南吗？

java.lang.OutOfMemoryError: Could not allocate JNI Env at java.lang.Thread.nativeCreate(Native Method) at java.lang.Thread.start(Thread.java:730) at java.util.concurrent.ThreadPoolExecutor.addWorker(ThreadPoolExecutor.java:941) at java.util.concurrent.ThreadPoolExecutor.processWorkerExit(ThreadPoolExecutor.java:1009) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1151) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:607) at java.lang.Thread.run(Thread.java:761)

Answer 1

Timer timer = new Timer();
timer.schedule(new TimerTask() {
    @Override
    public void run() {
        // call request method
    }
}, REQUEST_PERIOD_AS_MILISECONDS);



// You need to cancel it when you are done with it as following:
if (timer != null) {
    timer.cancel();
    timer = null;
}
