Hi, I published an app to the Google Play store using Construct 2 and Intel XDK. I recently wanted to update the app and when trying to test on my device, it won't let me install the latest build (Crosswalk for Android). I tried clearing my cache, uninstalling the game, a previous build, another device and then finally tried a completely different apk. Any idea what might be wrong? I am using AdMob which was part of the problem I had before, but I even tried completely deleting AdMob from my game and I still can't install it. Is there a better way to trouble shoot or identify what the problem is? I asked on the Intel forums, but no response yet. Thanks.
TLDR, what are some reasons that would cause an apk to fail during its installation after building it out for Crosswalk for Android?
