public class SplashActivity extends Activity {

                 private static String TAG = SplashActivity.class.getName();

                   private static long SLEEP_TIME = 5;    // Sleep for some time

                                   @Override

                   protected void onCreate(Bundle savedInstanceState) {

                      super.onCreate(savedInstanceState);

                      setContentView(R.layout.activity_splash);

                 

                      // Start timer and launch main activity

                      IntentLauncher launcher = new IntentLauncher();

                      launcher.start();

                   }

                 

                   private class IntentLauncher extends Thread {

                       * Sleep for some time and than start new activity.

                       */

                      public void run() {

                         try {

                            // Sleeping

                            Thread.sleep(SLEEP_TIME*1000);

                         } catch (Exception e) {

                            Log.e(TAG, e.getMessage());

                         }

                 

                         // Start main activity

                         Intent intent = new Intent(SplashActivity.this,mainactivity.class);

                         SplashActivity.this.startActivity(intent);

                         SplashActivity.this.finish();
