Travis CI & CodeCov Android

I am trying to use Travis CI and get it to run through the tests to see the results on codecov.

}

task clean(type: Delete) {

}

The test we are trying to run is an instrumented test. The output on the Travis log looks like this:

com.example.fabian.tinf15b4_lsmf.SeeMovieDetailsTest > seeMovieDetails[test(AVD) - 5.0.2] [31mFAILED [0m
    java.lang.NoSuchMethodError: No virtual method releaseConnection()V in class Lorg/apache/http/client/methods/HttpRequestBase; or its super classes (declaration of 'org.apache.http.client.methods.HttpRequestBase' appears in /system/framework/ext.jar)

    at org.yamj.api.common.http.DigestedResponseReader.processRequest(DigestedResponseReader.java:119)

Tests on test(AVD) - 5.0.2 failed: Instrumentation run failed due to 'java.lang.NoSuchMethodError'
:app:connectedFreeDebugAndroidTest FAILED

Also there was the autogenerated Test which simply adds two numbers and checks the result but Travis did not even go through it.

Can anyone please help fixing this mess?
