Failed to generate coverage report for test cases

[davidyoung8906]

I'm running well with all the test cases with Junit. But when I use "ant coverage" trying to generate test cases report, The error below appears:

[exec] com.todoroo.astrid.dao.TaskDaoTests:.....INSTRUMENTATION_RESULT: shortMsg=java.lang.IllegalStateException
[exec] INSTRUMENTATION_RESULT: longMsg=java.lang.IllegalStateException: database /data/data/com.timsu.astrid/databases/databasetest (conn# 0) already closed
[exec] INSTRUMENTATION_CODE: 0
[echo] Downloading coverage file into project directory...
[exec] remote object '/data/data/com.timsu.astrid/coverage.ec' does not exist

BUILD FAILED

On the logcat, it shows that:

Seems like something wrong with sqlite part, but never occured during the execution of JUnit test cases.
Any comment is welcomed!

That's kind of weird. Our code coverage is pretty bad, unfortunately, but this is the ant command that we use:

cd astrid
ant all clean 
cd ../tests
ant clean emma debug install coverage
