Whenever I introduce new functionalities to my .NET MAUI app and create a new APK, I aim to seamlessly update the existing installations on users' devices without losing any of their data. This means that when users install the updated version of the app, they shouldn't experience any loss or corruption of their previously saved data.
To achieve this, I need a solution that ensures a smooth transition from the old version to the new one, without causing any disruptions to the user experience. Since I'm utilizing an SQLite database for storing app data, the database must remain intact during the update process.
However, when I attempt to install the new APK over an existing installation on a device where the older version is already present, I encounter an "App not installed" error. This error indicates that there might be an issue with the package, preventing it from being installed properly.
Error: App not installed as package appears to be invalid
I tried to get the solution over the Internet but did not get any resolution
