Thank you - good thinking.
For the benefit of others reading, this is how I did it in the end:
String vc = null;
try {
vc =
getPackageManager().getPackageInfo(getPackageName(),
0).versionName;
} catch (NameNotFoundException e)
e.printStackTrace();
}
boolean hasSeenUpdateVersion = settings.getBoolean(
"hasSeenUpdateVersion", false);
if (!hasSeenUpdateVersion) {
// show a dialog here
SharedPreferences.Editor editor = settings.edit();
editor.putBoolean("hasSeenUpdateVersion" + vc, true);
editor.commit();
}
