Instruction for homework review

When reviewing homeworks, you have to compare the homework submissions in order of quality, and leave comments.

Quality

To judge quality, consider:

• Does the application work, and does it meet the requirements of the homework?
• Code quality. Is the code readable, concise, elegant, and well-commented? Ask yourself if you would consider using that code in an important hypothetical application you could be writing.
• Is the application nice and easy to use? Or is it kludgy?

Comments

Please give helpful comments to the author. Not something like "hey funny picture on top page!". Something like "you could have use startActivityForResult() rather than startActivity()", or "please write readable comments -- the code for you array adaptor is quite messy" or "Do not use explicit strings in your code, always use string resource ids".
