  • 0

I have developed android apps, and have a web server application which serves REST style JSON, to the apps.

My apps are strongly dependent on that web services but as traffic gets higher, users’ complaint started, as force close problems. I am not sure but maybe my server (AWS small instance) may not answer all requests correctly or in time.

I am planning to retry the web request when a problem on getting json response arise instead giving the error/net-connection alert.

I guess there are many developers who integrates apps with web services, so what is the good practice on handling network problems?

Or is the frequency of such network problems acceptable?

I take about 10-20 problem per day.
I have about 200.000+ web requests per day, for a AWS small instance (1.7 RAM), dedicated to server Tomcat. I analyze the logs there is no clue, no error log. Also the errors are spreaded.

    You need to start with analyzing the problem, and determine the root cause or root causes of your issues. You always need to take into account that

    • a network connection might drop
    • a users switches from 3G / WiFi
    • the android devices “thinks” it’s connected while in fact it’s not

    Also, be very sceptical when using the Android ConnectivityManager / NetworkInfo. Only trust it when it states that it is not connected. If it is connected, check it yourself (as sometimes, user is on a hotspot and the only connectivity he has is with a login page).

    The application needs to handle all these scenarios properly. The way it’s presented to the user depends on the use-case (do you want the user to be informed of the error, do you silently ignore it and just retry, ….)

    In terms of retrying webservice connections, there are several ways to implement this :

    • exponential backoff
    • periodic rescheduling
    • event-driven triggering
    • retry-after moratorium intervals

    You need to start by putting sufficient logging both on the client (Android) and on the server (AWS) so that you can analyze the issues and draw the proper conclusions.
