Everytime I try to sideload an application I get this error for some reason. Probably just started happening since I updated to the latest OS. It use to work before.
I think I figured out the probably, I think the app that I was trying to sideload was a native app. I didnt even know you could sideload native apps so I guess the new update has blocked that feature. So i guess there's not a problem at all. Just a few android apps I had stop working now. Probably was left open for devs to test their work. I wonder how they will test them now.
