Build installation issue

Post by nimje.sanjay » Wed Apr 23, 2014 2:59 am


My device is already having an App in built in it.

When I am trying to install the upgraded version of App on the device I am seeing the below error message:
Installing the app has failed. It seems the app is already installed on the device with a different certificate in use. Ranorex instrumented apps need the Android Debug certificate to work correctly. Please uninstall the existing app from the device and retry the deployment process afterwards.

I am able to install the App using the below command from command prompt:
ADB install -r <Path of the build>

The problem here is Ranorex tool is not able to replace the existing file on the device and certificate issue error message is thrown.

I am using the Ranorex Licenced 4.1.0 version.

Please suggest a solution for the same.
It is blocking our automation.

In order to install a newer version of your application on a device, the older version must be uninstalled.
If you have any problems deleting your application from the device, please have a look at this Blog
