No local sync point found

I'm gonna be completely honest, I have no idea what this error is and what it means, all I know is that my app is not working properly because of it and idk how to fix it. It only shows up in the logcat after I try and run the app, and its not anywhere in any of my activities.

"APK" is the Android Package Kit and it's Android's equivalent to an executable JAR (more or less). That is, when you create an Android application, you bundle it up into an APK which can then be installed into a compatible Android device. Or into the desktop Android device simulator when you're doing development.

Basically, it's saying that the APK you are trying to install cannot be found at the indicated location or that it's corrupt. So you need to create a clean APK and install it.
