Thanks for all the answers.

Rolando - the best way to develop a custom Andrdoid app for Salesforce is to use our Android Mobile SDK. The Mobile SDK provides native Android (i.e. Java) wrappers for the Salesforce REST API and takes care of all the low-level plumbing (like OAuth 2.0 authentication) that you need in order to connect to a Salesforce backend from an Android device. The SDK even has a secure offline module called SmartStore that lets you save data on the Android device securely (it uses SQL Cipher under the covers). Not sure what  you mean by Digital Signature and so I can't answer that part of the query. 

Here are a couple of resources for you to learn more about the Android Mobile SDK - https://github.com/forcedotcom/SalesforceMobileSDK-Android, http://wiki.developerforce.com/page/Getting_Started_with_the_Mobile_SDK_for_Android, http://events.developerforce.com/conferences/dreamforce?session=22341.

Hope this helps.
