How can I utilize Yahoo Weather API in android

Question

I want to develop an app using Yahoo Weather API for android. I want to get current and forecast weather details.

I have tried it from different sources (e.g.:https://github.com/survivingwithandroid/WeatherLib, Getting error with Weatherlib API Android and Unable to execute activity in android for weatherlib) and getting different errors which I M Unable to resplve. Is there anything that I can get a proper tutorial or guide!

The project is not meant for Eclipse but you should use Android Studio. Anyway there are under https://github.com/survivingwithandroid/WeatherLib/tree/master/lib/release you can find the jars you can import into eclipse. I advice you to use Android Studio
