Manage API calls with Java [Android] -


i trying manage request calls. here situation. using retrofit 2 rxjava. have api request call in onresume method in fragment. when switch tabs in application or rotate phone onresume method gets called again , if call slow send 2 same requests , 2 identical responses. have idea how can prevent this?

i not send second api call if first 1 ongoing or somehow merge 2 responses 1 if calls same.

thanks

you can create flag wrapping api , make false while requesting , true on response

private boolean canrequest = true; void onresume(){ if(canrequest){    canrequest = false;    fetchdatausingretrofit(new responsecallback(){        void onresponse(){          canrequest = true;        }     }); } }

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

(int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
