1) java.lang.SecurityException: Permission Denial: starting instrumentation ComponentInfo{com.appname.test/sh.calaba.instrumentationbackend.ClearAppData} from pid=2904, uid=2904 not allowed because package com.appname.test does not have a signature matching the target com.appname.

this is seen when you are trying to run tests against app which was built on different machine but tests are run from your machine. In this case application built on different machine will have different signature (incase you haven't shared the keystore file with them) and your test server cannot communicate with the app

manually uninstall app from device
take the apk file and resign it - calabash-android resign app.apk
