you can use SharedPreferences. This is an example:

SharedPreferences mPrefs = getSharedPreferences("MyPreferences", Context.MODE_PRIVATE);
SharedPreferences.Editor editor = mPrefs.edit();
editor.putBoolean("firstTime", true);
editor.commit();

So you can check if firstTime is true doing this:

SharedPreferences mPrefs = getSharedPreferences("MyPreferences", Context.MODE_PRIVATE);
if(mPrefs.getBoolean(firstTime, false){
    //show screen
}

You can put this code in your Activity entry point, the first Activity you reach when the app starts. – Stefano Ortisi Jun 27 '12 at 16:31

Set your AndroidManifest to start the MainActivity as the default activity.

Then in the onCreate check if the user has registered (perhaps store this in SharedPreferences), if they have NOT registered - instantly start the intent for your RegisterActivity, otherwise carry on as normal.
