Question

Hello I would like to display an other splashscreen after the default one, if the App starts for the first time(right after installation e.g.)

So I wrote this. But the new Activity does not start it stays at the Splash screen. Can somebody say whats wrong with it?

import android.app.Activity;
import android.content.Intent;
import android.content.SharedPreferences;
import android.os.Bundle;
import android.preference.PreferenceManager;
import android.widget.TextView;

    public class splash extends Activity {
         private Thread splashTread;

        @Override
        protected void onCreate(Bundle savedInstanceState) {
            // TODO Auto-generated method stub
            super.onCreate(savedInstanceState);
            setContentView(R.layout.splash);

            SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(this);
            if(!prefs.getBoolean("firstTime", false)) {
                // run your one time code
                 Intent i = new Intent(splash.this, main.class);

                         startActivity(i);
                SharedPreferences.Editor editor = prefs.edit();
                editor.putBoolean("firstTime", true);
                editor.commit();


             // thread for displaying the SplashScreen
             splashTread = new Thread() {
                 @Override
                 public void run() {
                     try {
                         synchronized(this){

                                 //wait 2 sec
                                 wait(2000);
                         }

                     } catch(InterruptedException e) {}
                     finally {
                         finish();



                         //start a new activity
                         Intent i = new Intent();
                         i.setClass(splash.this, main.class);
                                 startActivity(i);

                         stop();
                     }
                 }
             };

             splashTread.start();

        }

    }
    }

Thanks.

From what I’ve seen, your code runs the same Activity (main) regardless of whether the launch is the first time or not. I’m assuming your purpose is to immediately launch the alternate splash screen if it’s the first launch, otherwise to proceed to the main Activity after 2 seconds. Also, I would recommend using a Handler rather than a Thread, since you’re only making use of it once, and on a delay. Try this:

    public class splash extends Activity
{
    private Handler handler = new Handler()
    {
        public void handleMessage(Message msg)
        {
            Intent i = new Intent(splash.this, main.class);
            splash.this.startActivity(i);
                                 this.finish()
        }
    };

    protected void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);

        SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(this);
        if(!prefs.getBoolean("first_time", false))
        {
            SharedPreferences.Editor editor = prefs.edit();
            editor.putBoolean("first_time", true);
            editor.commit();
            Intent i = new Intent(splash.this, otherSplash.class);
            this.startActivity(i);
                                 this.finish();
        }
        else
        {
            this.setContentView(R.layout.splash);
            handler.sendEmptyMessageDelayed(0, 2000);
        }

    }
}
