Debug with Android Source in your Android App

As a new Android developer, I discovered a tip that has helped me tremendously as I've worked on Saver, a savings planning application. To debug with Android source and Eclipse, install the following packages (usually via Help -> Install New Software...):


Restart Eclipse to complete the installation. Support is available (as of 09/13/2011) for Android versions ranging from 1.5 (Cupcake) to 2.3.4 (Gingerbread).

JUnit - Integrating Ant

I currently use Ant as my build tool for personal projects. It's easy and flexible enough for my needs.

The build.xml file I use for my template project is available here.

The general steps for the test task are are as follows:
1) Make a test report directory
2) Specify a property that serves as a match for tests
3) The junit task takes a variety of arguments
     fork - run tests in separate JVM
     printsummary - print a separate line for each test case
     haltonerror - halt the build if an error occurs during a test
     haltonfailure - halt the build if a test fails
4) Specify a formatter and whether or not to use file based output (I set it to false as I prefer to see the output at console initially)
5) Define a set of tests based on pattern matching
6) Define a classpath 

More information on the JUnit Ant Task is available here.
