Using the Eclipse GUI does not allow one to easily: (a) Add custom build steps (b) Use an automated build system (c) Use build configurations (d) Build the release project with one command.Fortunately, the Android SDK comes equipped with support for Ant.This tutorial will show you how to incorporate an Ant build script into your Android projects,even if you still develop with Eclipse.

Arguably the worst part in playing around with Android is its insistence to put that ugly title bar above everything I do as a default to Activities. Thankfully, the framework allows one to change this behavior.This post is going to explore the ways in which we can create custom title bars and more importantly just how far we can push the limits.

Using Java annotations, developers can show their intent and let AndroidAnnotations generate the plumbing code at compile time. Few Features are * Dependency injection: inject views, extras, system services, resources, ... * Simplified threading model: annotate your methods so that they execute on the UI thread or on a background thread. * Event binding: annotate methods to handle events on views, no more ugly anonymous listener classes! * REST client: create a client interface, AndroidAnnotations generates the implementation. * AndroidAnnotations provide those good things and even more for less than 50kb, without any runtime perf impact!
