How can I improve performance of my android Application?

Question

I am working on an application where whole data came from the API. I mostly used fragment in my application at some fragment my application did not take too much time. But at some Fragment It take to much time to display the Layout. When I debug the application I saw that data has came rapidly but it take time to display the data . And in the Log I got a message "this Application doing lot of task in its main thread". Is there any way to improve the performance of the application ?

As I told my application take time in displaying some data . Is this is the issue of complex layout? — Abhishek Bhardwaj, Feb 21 '17 at 09:22
as you haven't posted any code (which you should) so it is just a wild guess. May be you are doing some other time taking tasks like fetching contacts etc. They should also be moved to background thread — Vivek Mishra, Feb 21 '17 at 09:23

you can use volley libraries to download data fast and for image use picaso and for database use relm database its fast api dont use old style httpcliant or json parser its slow.and first display data from database then store data of api in database and again dispaly from database in onpause method after some time(dippents on our data how much time tack to load ).if you have large data in json use pagination tachniq.

In my case, I am facing the same issues when I try to parse the JSON Results as a markers in GoogleMap.For <1000 Json Objects it works fine But when the Json Result Object Exceeds >1000 my app gets hangs and it takes too much of time to load. Here What I have done to fix the issue

i am assuming you are deal with JSon Data.

Reduce the Size of JSon Results Based on Some Conditions.
Use small tags for JSon Lables(for Ex. instead of lable latitude use l,instead of longitude use lo)
Avoid HttpClient for Network Calls,Use Appropriate Network Library(like volly,Retrofit,OkHttp) based on Your Requirement NetworkLibraries Difference
If you have any Calculations with the Result data Try to done it from the Server side as much as Possible
Remove Unwanted data in the JSON Result.
