问题 I am following up image cashing tutorial using Volley on Android developers, I am having problem with requesting an image request and caching it, I guess because of the singelton that I created (copied from the tutorial). My Eclipse is giving error in the getInstance(this) because this is context and I am requesting an image I guess.

问题 I use Volley library to connect with server in my app. Now, I have to send request in background every 5 minutes also when app is not running (killed by user). How should I do it?
