Android: Unable to download from play store

Question

I am developing an Android App. I was able test it on my device successfully. So I pushed the released version on Google Play store. Now I uninstalled the debug build from my device and tried to download it from the Play Store. But when I click on install button, I am getting this error.

you cannot install this app because another user has already installed an incompatible version on this device...

I am only using Google Play services. Not using any storage or anything that might be different for different users and Android L. What changes should I make in my app source to resolve this?

Edit

Answer 1

Somehow adb shell pm uninstall com.packagename did not work for me. I am not sure if this was because I was on a lollipop device.

The answer suggested in this link did the trick. Hope this helps someone else.

For Redmi or Mi Phones, the debug app was got installed on second space.

1. Go To Setting -> Second Space -> Open Second Space.

2. Settings -> App - > downloaded app list.

3. Click on the application, You want to Uninstall.
4. Click on Uninstall.
5. Back to First space from setting.

Or For Other Phones

1. Go to settings -> apps -> downloaded app list
2. You can see the installed applications in the list

Answer 3

I solved this issue by uninstalling debug version of the app and then clearing data of play store app.

If this still doesn't work, you can follow these steps given in this site.

Go to any root file manager, and navigate to directory: root >> data/data folder.

Find the relevant folder of that app which you were installing from play store.

Then delete that folder. [Note: Here you will loose all data related to that app].

Now go to play store, and try to install that app again.

Check you have fixed your error.

Hope this helps!

Update: Thanks Abhishek, you can also try uninstalling the app using adb:

adb shell pm uninstall com.packagename
