Reinstalling of android-server in android-drone fails when other version is specified ------------------------------------------------------------------------------------- Key: ARQ-1273 URL: https://issues.jboss.org/browse/ARQ-1273 Project: Arquillian Issue Type: Feature Request Security Level: Public(Everyone can see) Components: Extension - Android Affects Versions: 1.0.0.Final Reporter: Stefan Miklosovic Assignee: Karel Piwko Priority: Optional Since there is the possibility to have an Android virtual device connected and online while doing some tests so starting up the emulator is not neccessary every time one is testing something, the android-drone module installs (and reinstalls) an android-server.apk on the device in order to prepare it for e.g testing via android-extension-drone. When running the test, specifying one version of the apk server (e.g. 2.16), this APK is installed. In the case we are executing the test the second time with the same version of the APK, all is good since the APK is just reinstalled. The error arise when we are trying to reinstall the APK when other version of the server is specified (e.g. 2.21.0) because it seems that Android checks upon reinstalling if the certificates of APK files match and in this case, it is not true. The next error appears while doing so: {code}org.jboss.arquillian.android.api.AndroidExecutionException: Unable to install APK from (path)/android-server-2.21.0.apk.

The command which writes out the list of all installed applications is {code}pm list packages -f{code} so this can be easilly checked and tested for the presence of the string {code}package:/data/app/org.openqa.selenium.android.app-1.apk=org.openqa.selenium.android.app{code} or its appropriate part.
