Check If Application Is on Its First Run

Check if application is on its first run

The following is an example of using SharedPreferences to achieve a 'first run' check.

public class MyActivity extends Activity {

    SharedPreferences prefs = null;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        // Perhaps set content view here

        prefs = getSharedPreferences("com.mycompany.myAppName", MODE_PRIVATE);
    }

    @Override
    protected void onResume() {
        super.onResume();

        if (prefs.getBoolean("firstrun", true)) {
            // Do first run stuff here then set 'firstrun' as false
            // using the following line to edit/commit prefs
            prefs.edit().putBoolean("firstrun", false).commit();
        }
    }
}

When the code runs prefs.getBoolean(...) if there isn't a boolean saved in SharedPreferences with the key "firstrun" then that indicates the app has never been run (because nothing has ever saved a boolean with that key or the user has cleared the app data in order to force a 'first run' scenario). If this isn't the first run then the line prefs.edit().putBoolean("firstrun", false).commit(); will have been executed and therefore prefs.getBoolean("firstrun", true) will actually return false as it overrides the default true provided as the second parameter.

Check if an application is on its first run with Flutter

Use Shared Preferences Package. You can read it with FutureBuilder, and you can check if there is a bool named welcome for example. This is the implementation I have in my code:

return new FutureBuilder<SharedPreferences>(
      future: SharedPreferences.getInstance(),
      builder:
          (BuildContext context, AsyncSnapshot<SharedPreferences> snapshot) {
        switch (snapshot.connectionState) {
          case ConnectionState.none:
          case ConnectionState.waiting:
            return new LoadingScreen();
          default:
            if (!snapshot.hasError) {
              @ToDo("Return a welcome screen")
              return snapshot.data.getBool("welcome") != null
                  ? new MainView()
                  : new LoadingScreen();
            } else {
              return new ErrorScreen(error: snapshot.error);
            }
        }
      },
    );

Determine if Android app is being used for the first time

Another idea is to use a setting in the Shared Preferences. Same general idea as checking for an empty file, but then you don't have an empty file floating around, not being used to store anything

How can I check if a program is running for the first time?

Seems that your problem is actually that if you move executable to another location/folder on the same pc, it loses somehow the information about the fact that it was already run at least once.

Using UserSettings, on Properties.Settings.Default.FirstRun should resolve your problem.

Something like this, a pseudocode:

if(Properties.Settings.Default.FirstRun == true)
{ lblGreetings.Text = "Welcome New User";
  //Change the value since the program has run once now
  Properties.Settings.Default.FirstRun = false;
  Properties.Settings.Default.Save(); }
else
{ lblGreetings.Text = "Welcome Back User"; }

Look on this sample how to achieve that in more detailed way.

Detect First Run

savedInstanceState is more for switching between states, like pausing/resuming, that kind of thing. It must always be created by you, also.

What you want in this case is SharedPreferences.

Something like this:

public static final String PREFS_NAME = "MyPrefsFile"; // Name of prefs file; don't change this after it's saved something

@Override
public void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);

    SharedPreferences settings = getSharedPreferences(PREFS_NAME, 0); // Get preferences file (0 = no option flags set)
    boolean firstRun = settings.getBoolean("firstRun", true); // Is it first run? If not specified, use "true"

    if (firstRun) {
        Log.w("activity", "first time");
        setContentView(R.layout.activity_clean_weather);

        SharedPreferences.Editor editor = settings.edit(); // Open the editor for our settings
        editor.putBoolean("firstRun", false); // It is no longer the first run
        editor.commit(); // Save all changed settings
    } else {
        Log.w("activity", "second time");
        setContentView(R.layout.activity_clean_weather);
    }

}

I basically took this code directly from the documentation for Storage Options and applied it to your situation. It's a good concept to learn early.

Check for Android Application is First run or not?

Why don't you just write an if else statement in the main method of the main page?
If first launch > splashscreen redirect
If run xx > Login redirect.

To detect the first time an app is launched you could make a sharedPreference (see this thread: How to use SharedPreferences in Android to store, fetch and edit values or Check if application is on its first run)

Good luck.

How to check if it's the first time a user launches an app using is_first_run library?

I think you should use Shared preferences for better state management.
However, with this library, you can try the reset() function.

After calling reset(), calling isFirstRun() will return true as long as the app is running. After a restart, it will return false again. The first call of isFirstCall() will return true, subsequent calls will return false again.
