Splash.java

 public class Splash extends Activity{  
MediaPlayer ourSong;
@Override
protected void onCreate(Bundle savedInstanceState) {
    this.requestWindowFeature(Window.FEATURE_NO_TITLE); 
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);
         setContentView(R.layout.splash);  

    ourSong = MediaPlayer.create(Splash.this, R.raw.splashsound);     
    ourSong.start();

    Thread timer = new Thread(){
        public void run(){
            try{
                sleep(2000); 
                }
              catch (InterruptedException e){
                e.printStackTrace(); 
                }
              finally{
                  Intent intent = new Intent(Splash.this, MainActivity.class);                                     
                  startActivity(intent); 
                  }
            }                                   
        };
         timer.start();   
         }  
@Override
protected void onPause() {
            // TODO Auto-generated method stub
    super.onPause();
    ourSong.release();
    finish();
          } 
       }

Prefs.java

public class Prefs extends PreferenceActivity{

@SuppressWarnings("deprecation")
@Override
protected void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);

    addPreferencesFromResource(R.xml.prefs); 
    }
}

prefs.xml

<?xml version="1.0" encoding="utf-8"?>
<PreferenceScreen
  xmlns:android="http://schemas.android.com/apk/res/android">

     <ListPreference
       android:title="Application Start Preference"
       android:summary="This preference allows to select how the app will start"
       android:key="listPref"
       android:entries="@array/splash"
       android:entryValues="@array/splash_values" />          
</PreferenceScreen>

arrays.xml

<?xml version="1.0" encoding="utf-8"?>
 <resources>   
  <string-array name="splash">
      <item>start app without splash screen </item>
      <item>start app with splash scrren only</item>
      <item>start app with splash screen and music</item>
  </string-array>

  <string-array name="splash_values">
      <item>1</item>
      <item>2</item>
      <item>3</item>

  </string-array>    
</resources>

UPDATE: i tried the below code but whats happen is app run normally start with splash then go to mainactivity then i press preference in option menu its OK it open preference page then press on listpreference it rise the dialog of 3 radiobutton and if i press any one of radiobuttons its ok , then i back and back till exit app , then open it again it open directly to show the mainactivity without splash then crashes immediately.

also line 23 in logcat is:

 int splashType = getPrefs.getInt("listPref", 0);

     SharedPreferences getPrefs = PreferenceManager.getDefaultSharedPreferences
             (getBaseContext());

 int splashType = getPrefs.getInt("listPref", 0);
  switch (splashType) {
  case 2:
Intent intent = new Intent(Splash.this, MainActivity.class);                                     
       startActivity(intent);
  break;

  case 1:

         }
      }                          
    };
   timer.start();       
break;

 case 0:

   ourSong.start();

Thread timer1 = new Thread(){

                    }
                   }

Answer 1

You can try something like that to get the stored user preference and then take relevant action:

SharedPreferences sharedPrefs;
sharedPrefs = PreferenceManager.getDefaultSharedPreferences(this);
String userSplashValue = sharedPrefs.getString("listPref", "1");

if (userSplashValue.equals ("1")) {
 // choice 1
}
else if (userSplashValue.equals("2")) {
 // choice 2    
}
else if (userSplashValue.equals ("3")){
 // choice 3    
}
