Answer 1

Yes, that is normal for Xamarin.Android apps built in debug mode.

If you Clear Data you are removing directories/files that are used for debugging:

Before clearing data:

.:
drwxrwx--x   2 u0_a93 u0_a93 4096 2017-09-11 21:15 cache
drwxrwx--x   2 u0_a93 u0_a93 4096 2017-09-11 21:15 code_cache
drwxrwx--x   5 u0_a93 u0_a93 4096 2017-09-11 21:24 files
lrwxrwxrwx   1 root root     60 2017-09-11 21:15 lib -> /data/app/com.sushihangover.GeneticCancerDNAMapper-1/lib/x86
    ./cache:
    ./code_cache:
    ./files:
        drwxrwxrwx 3 u0_a93 u0_a93 4096 2017-09-11 21:24 .__override__
        drwxr-xr-x 2 u0_a93 u0_a93 4096 2017-09-11 21:24 .config
        drwxr-xr-x 3 u0_a93 u0_a93 4096 2017-09-11 21:24 .local
        ./files/.__override__:
            drwxrwxrwx 2 u0_a93 u0_a93 4096 2017-09-11 21:24 links
        ./files/.__override__/links:
            lrwxrwxrwx 1 u0_a93 u0_a93   70 2017-09-11 21:24 libmonosgen-2.0.so -> /data/app/Mono.Android.DebugRuntime-1/lib/x86/libmonosgen-32bit-2.0.so
        ./files/.config:
        ./files/.local:
            drwxr-xr-x 2 u0_a93 u0_a93 4096 2017-09-11 21:24 share
            ./files/.local/share:

After clearing data:

.:
lrwxrwxrwx   1 root root     60 2017-09-11 21:25 lib -> /data/app/com.sushihangover.GeneticCancerDNAMapper-1/lib/x86

This data is not needed for release builds and the Application.DataDir is not used by Xamarin's runtime in release builds.
