Ranorex Forum

I have a new mobile app to automate, but when I try to instrument that I am getting the below error.

The developers has confirmed that the apk is Non obfuscated and the API version is 21.
What to do next?

Hi,

I'm afraid, it's impossible to tell what's wrong without seeing the app. I would suggest to start with instrumentation wizard settings... Enable for example "Debug" option and see, if there is something interesting in instrumentation log. Also, you may try to enable Multidex, Static and Redistribute smali options.

If nothing, helps, you will have to contact Ranorex support. But they may need access to the apk in question. Without analyzing it, there is almost no chance to help with this kind of error.

Hello Pavel,

Than you for the reply. I have already contacted the support and waiting reply.

By the way I have tried the advance setting (Different combination) but of no luck. I am getting the below error message.

Hi,

Try to uninstall the existing app from Android device, before instrumenting and installing this new one. Check this post about INSTALL_FAILED_VERSION_DOWNGRADE error...
