If the network is poor, will the app with web request run slowly?

In my app, the accelerometer has a callback function called every second, in which a web request function will be invoked to upload accelerometer data after collecting. Well, if the network is poor, will the web request get a timeout and slow down the whole app?

Yes, the network speed can make a real difference, as can the speed of your server. Doing makeWebRequest calls will also run faster in the sim than on a phone as the pc/mac probably has a high speed connection and BLE isn't involved to get it from the device to the phone.

I can see where trying to send data every second could cause issues as even during prime conditions you could run into things.

Maybe try bundling the data so that every 15 seconds you send 15 seconds of data to help things.

This isn't like some things where when a program starts, it establishes the connection, then sends data as often as needed, and disconnects when the program ends. Each time you do a makeWebRequest, it creates the connection, sends the data, then disconnects.

Thanks, Jim. Recently, as the user report, my app encountered some problems related to the network condition probably.

Is there any API to detect the network quality? OFC, I can detect the time-consuming of a request by timing to know that.

compare System.getTimer() before you do the makeWebRequest() and after the callback when it completes and compare.
