While developing android apps, we find that sometimes the apks we build don't get installed - the package manager just says Not Installed. The reason is apparently that if the same app is currently installed with a different signature, it will not get overwritten.
Uninstalling via long press on the home screen on my LG Q6 was not sufficient.
To uninstall cleanly, the way was as listed at this page:
Settings - Apps - Select the app to uninstall - Choose Force Stop
Then choose Storage - Clear Cache - Clear Data
Return to the app screen - choose Uninstall
After doing this, the apk will install. If it doesn't there may be something wrong with the signing etc. which will be the subject of another post of mine.
