I use http://api.openweathermap.org/data/2.5/weather to show weather it is working in the emulator when I send location in it using location setting but it is not working on a real device.
It does not even show any error message in the log.
Can Any one tell me what I am doing wrong?
I add all permissions in Androidmanifest.xml also.
