Unable to run app on device using android studio

Question

I have been trying to use android studio and every time I deploy an app on a device, it gives me an error saying:

Installation failed since the device possibly has stale dexed jars that don't match the current version (dexopt error).

In order to proceed, you have to uninstall the existing application.

I have tried using Build->Clean Project and yet it seems to do no good. I have also tried deleting the file from /data/local/tmp on device (as my phone is a rooted one), but, all in vain.

If anyone knows a way out, please, please help.

Answer 1

Uninstall the application from the device. Check the storage space. Once Restart the mobile and try to install it
