I have an app on google play store, when I installed via google play store on my phone (Android version 6.0) it functions well, When I extract the APK and try to re-installed it I get this "App Not Installed" I not sure what is causing this, I have try to free space, clear data with no effective solution

Your device is reading the extracted APK as external third party software. By default Android allows installation only directly from the Play Store. The Android app not installed error can be combated after resetting app permissions. Go to Settings > Apps > Reset App Preferences/Reset Application Permissions. After this, third-party software can be installed on your device

I don't think it is a SO question since you are just downloading application from Google Play and installing from File Explorer. I think it's suitable in Android Enthusiast. Anyway, there's two reason of having the issue

1. The APK is corrupted (you must download another APK (and remember to check if that's not corrupted either) and you can't do anything with the current APK)

2. Check you are selecting correct APK sometimes Android devices show a APK or file which doesn't exist either.
