Do you have your logcat set to verbose? Are you sure you're logging it correctly? Can you show me your code?

yah! i have been set the logcat to verbose.

Code is: MainActivity.java :

Are you testing the code on a physical device or an emulator? Try running it on an emulator as a physical device often has other things its logging and it may clutter your output.

Also when trying to run it on both the physical device and emulator, try to filter out the results by typing MainActivity in the search bar next to Log Level where your output is.

I've tested your api key and it does result in feedback from the api. Possible issues can include connectivity to the api. If you've got it up and running, you should consider reseting your api key from your developer account at https://developer.forecast.io/

This might sound silly but make sure you aren't still in airplane mode from the previous exercise. That's what happened to me :S
