how to check the first time user of my App in android?

Question

hi all,

In my App, first it shows a splash screen. after that another activity, then my main activity must be show. this is my design plan. the second activity(i.e before main activity) must be show for the first time user of the app. if he/she closes the app.splash screen will redirect to main activity automatically. how to do this ? Any Idea? i am developing my app for android phones.

Answer 1

You'd need to save data somewhere, in your case it might be easiest to just write out an empty file after the first run of the app. So you would check for the existence of this file and if it was there then you wouldn't show the second activity, and would just show the main activity.

Answer 2

Persist a flag in preferences and check it on startup. Change it's state after the splash is shown once.

Answer 3

You can e.g. use a sharedPreference-object to store a boolean value that tells you if this is the first time the user opens the application. Check the preference when the user starts the application, and if it returns true then show the middle screen.

private SharedPreferences mPreferences;
....
boolean firstTime = mPreferences.getBoolean("firstTime", true);
if (firstTime) { 
    SharedPreferences.Editor editor = mPreferences.edit();
    editor.putBoolean("firstTime", false);
    editor.commit();
    showMiddleActivity();
}

Something like that.
