How to display a one time welcome screen?

Question

In my android app, I need to design a Welcome Screen which will be shown to the user only once after the app is installed and opened. The app in question is a database drive

Answer 1

I created a SplashScreen with this:

package com.olidroide;


import android.app.Activity;
import android.app.ProgressDialog;
import android.content.Intent;
import android.os.Bundle;
import android.os.Handler;
import android.os.Message;


public class SplashScreen extends Activity{
/** Called when the activity is first created. */
     public ProgressDialog myDialog; 

    @Override
    public void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);
        setContentView(R.layout.splashscreen);

        new Handler().postDelayed(new Runnable() {

            public void run() { 
                myDialog = ProgressDialog.show(SplashScreen.this,"", "Loading", true);

                Intent intent=new Intent(SplashScreen.this,OtherActivity.class);
                SplashScreen.this.startActivity(intent);
                myDialog.dismiss();
                SplashScreen.this.finish();     
            }

        }, 3000);// 3 Seconds
    }
};
