I have just uploaded my app called 'Snippets' to the Android Market.
I created this app because I wanted to find a way to create a cheat-sheet for Intents. Not completely happy with the nth iteraration of the 'Notes' app, I decided to create an application that allows you to store, view, and email Java code.
Some of the features include:
* Snippet tagging
* Syntax highlighting
* Quick text insert (e.g. "{}" or "/* */", since these are near impossible to type quickly on a phone)
* Sending snippets by email
There is a free demo version of the app, which limits you to 3 snippets. The paid version allows you to create as many snippets as you want.
Some screenshots:
