based on my title.
Right now I am using vps from DigitalOcean to deploy the API (using laravel).
when I debug my apps, its really fast when getting data using WiFi. But, when I turn off the WiFi and turn on my data connection its really slow, almost take 10 sec to retrieve Json data, I don't know where is the problem, Mobile or Server.
I already upgrading the vps to 4GB, but its still not fixed the problem.
anyway I'm using AsyncHttpClient to retrieve data from API in android.
