This would annoy users of old devices even more. Imagine you download
an update, and then it's just a dialog that tells you to download an
app you can't find in the Market.
However, you could query the system version in e.g. onCreate of the
main activity (android.os.Build.VERSION.SDK, do NOT use SDK_INT, it
doesn't exist in 1.5!), and if it's Android 2.0 (5) or higher, show an
AlertDialog that points to the new version. You might linkt to the
Market entry with one button, like
dialog.setButton(getString(R.string.market), new
DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
try {
Uri uri = Uri.parse("market://details?
id=your.package.name");
startActivity(new Intent(Intent.ACTION_VIEW, uri));
}
catch( Exception e ) {}
}
});

Because the code can get pretty messy and bloated with lots of version
checks and reflection. It also forces you to do lots of things in code
that could otherwise be done in XML files, like using THEME_WALLPAPER.
Last not least there are some possibilities that can't be easily
worked around with reflection, especially added interface methods like
BaseExpandableListAdapter.getChild/ParentType(Count) that only work
since FroYo (while with older versions you have to bloat memory by
creating a new view for each element). I think there's also some
simlyfied button listener concept that was established after 1.5, but
I can't find it currently...
