Install Error -24

[RoyalBlader]

I purchased the app a moment ago, and it was unable to install on my Nexus 7, which is running Android 4.4.2 and not using the ART setting. I was able to install and play the demo version fine, but not the full app. I did get my refund from the Play store, but I would like to purchase that app, so I could play some DS games on my tablet.

Error -24 is rare, but you can get it anytime you install an app, and something goes wrong during installation.

If your device is rooted, then it should be easy to solve by deleting the folder /data/data/com.dsemu.drastic and installing again.

If it's not rooted, it's a bit more difficult, and mostly only a factory reset fixes the problem.
You can first try to delete data/cache of Google Play, Google Play Services and the Download Manager (in Settings > Apps > All) and rebooting your device afterwards.

Okay, thanks. I had to do a factory reset because I don't have my tablet rooted.

And by the way, does this app support ART? I have read that the app doesn't support it.
