Is there a way to run unit tests for Android from Eclipse in a way that will instrument the code and measure test code coverage?
I'm looking for a simple way to find out which parts of my application aren't tested yet, fix the test cases and see if that helped.
Disclaimer: I'm an Atlassian
The Atlassian Clover tool has also support for Android - it measures coverage for both application code and unit tests. Although in alpha stage, it works quite well - it works with Eclipse version 3.6.2 and higher.
If you want to find areas of your application which require improvement, then the following Clover features will be perfect for this task:
Oh, and the Clover HTML Report looks fantastic!

I've been used EMMA (android already support it) for code coverage (and android-junit-report for test reports), here is a summary:
android.bat update project -p project -n my_project -t android-16
cd project
ant emma clean debug
android.bat update project --library ..\project -p project_Test -n project_Test -t
android.bat update project -m ..\project -p project_Test -n project_Test -t
ant emma clean debug install I ddidn't use 'test' since I want to run my own instrument
adb shell am instrument -e coverage true -e coverageFile sdcard/coverage.ec -w com..myproject.test/com.zutubi.android.junitreport.JUnitReportTestRunner
adb pull sdcard/junit-report.xml
adb pull sdcard/coverage.ec
java -cp emma.jar emma report -r xml -in bin/coverage.em,coverage.ec
java -cp emma.jar emma report -r html -in bin/coverage.em,coverage.ec
Using Post-builds (Jenkins):
Don't need the emma.jar into libs

Install EclEmma from Eclipse Marketplace.
If you have <path to test project>/build.xml file rename it.
I was able to generate test coverage report by executing following from the console:
<path to android tools>android update test-project -m <path to app project> -p <path to test project> + Enter,
cd <path to test project> + Enter,
ant emma debug install test + Enter,
where <path to android tools> is /opt/android-sdk-linux/tools/ on my machine - the folder where android SDK is installed.
This generated <path to test project>/bin/coverage.html file.
If you get "wrong JAVA_HOME" error execute gksu gedit /etc/environment + Enter, correct JAVA_HOME, save the file, log out or reboot and try again.
