…anges. #517

Build fails because TaskProviderTest doesn't compile.
The project builds locally for me, so it looks like that compiling androidTest classes is not part of the default build task (gradlew build).

I am going to fix this now.

Travis build has failed twice now with this:

Skipping device 'test(AVD)' for 'opentasks:': Unknown API Level

 > : No compatible devices connected.[TestRunner] �[31mFAILED �[0m
Found 1 connected device(s), 0 of which were compatible.
:opentasks:connectedDebugAndroidTest FAILED

FAILURE: Build failed with an exception.

Not sure how to fix this. It seems it can't determine the API Level of the emulator. And only sometimes?
I am going to restart the build for a 3rd time now.

I already created an issue for that: #516

I saw that but the message copied there is different, I think that was an actual valid build fail for the TaskProviderTest.

All checks pass here now, ready for review.

Where did the annotations go?

Looks good.
