enable them and use connectedCheck instead of connectedAndroidTest

buildTypes {
    debug {
        testCoverageEnabled = true
    }
}

looks like some version does no work with android. The version "0.7.0.201403182114" looks good.

clean up the app/build.gradle file from stuff which is added for AndroidAnnotations
add dagger and butterknife to the app/build.gradle
replace all annotations
for jacoco code coverage you will need the following workaround to avoid issues with the generated $$ classes

task jacocoReport(type: JacocoReport) { doFirst { applyDaggerWorkaround('app/build/intermediates/classes/') } // avoid some side effects through revert renaming doLast { revertDaggerWorkaround('app/build/intermediates/classes/') } }

def applyDaggerWorkaround(String pathWithDaggerClasses) { def filePath = new File(pathWithDaggerClasses) if (filePath.exists()) { filePath.eachFileRecurse { file -> if (file.name.contains('$$')) { file.renameTo(file.path.replace('$$', '$')) } } } }

def revertDaggerWorkaround(String pathWithDaggerClasses) { def filePath = new File(pathWithDaggerClasses) if (filePath.exists()) { filePath.eachFileRecurse { file -> if (file.name.contains('$ModuleAdapter')) { file.renameTo(file.path.replace('$ModuleAdapter', '$$ModuleAdapter')) } } } }
