Detected problems with app native libraries.
libmonosgen-2.0.so: unauthorized access to "/system/lib_/libsqlite.so"

Hello, Im getting this warning at the start of running my app on Android 7N. In Android 8.0 or higher works fine and dosen´t appear anything

I have tried many things such as change my SQLite.Net-PCL nuget for sqlite-net-pcl from Frank A.Krueger but If I do that then I have this problem with my generic classes. I got some red lines like this:

   public T Find<T>(int codigo) where T : class
        {
            return dbConnection.Find<T>(codigo);  <-- Here is the red line
        }

And the descripcion is:
'T' must be a non-abstract type with a public constructor with no parameters to be able to use it as a 'T' parameter in the generic type or method 'SQLiteConnection.Find (object)'

Im new with Xamarin and c# so I got stucked here

Also I have tried to install the plugin SQLite.Net.Platform.Xamarin.AndroidN but this is only for Android 7. So I get incompatibility problems because my app is for Android 8.0 or Higher. If I try to change the compiler to 7.0 version the other packages that are installed for MonoAndroid 8.1 got the incompatibility problems too so this solution dont looks good for me.

Can some one help or give me another solution please ? Thank you
