The examples might need more comments

I'm a beginner Android developer and I've barely been exposed to basic Java before. As a result, I'm finding it difficult to understand some of these examples.

For instance I'm reading through "android_volley_examples / src / com / github / volley_examples / Act_SimpleRequest.java" and trying to figure out what you're doing and what parts I can apply to my own code. Within the code, there's interactions with the UI, additional function calls, and new functions added further down the file. Figuring out these parts took a while, and figuring out more of the examples might take even longer.

Could you add some simple comments that summarize what's going on to some of your examples?
