Question

my app sends a POST request to a server and gets a response using JSON format.

Sometimes my JSON response is “null” (if the request goes in time out).
In that case I need to notify the user about the timeout (dialog or toast) and avoid the app to crash.

How do I handle correctly the JSONException and avoid the app crash?

Thank you!

Answer 1

to avoid the crach of your app while parsing your json , try this :

if (jsonResponse == null) {
       // notify user
} else {
      try {
         // parse json here.
      } catch (JSONException e) {
        Toast.makeText(this,"Error on the response", 3000).show();
      }


}
