Splash screen not opening first

Question

Instead of opening the splash screen first, it opens the main activity then the splash screen.What might be be the problem.The splash screen wont go away until i press back button.

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.content.Intent;
import android.os.Handler;

public class MainActivity extends AppCompatActivity {
  private static int SPLASH_TIME_OUT=4000;
  @Override
  protected void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.activity_main);
  new Handler().postDelayed(new Runnable(){
     public void run(){
     Intent homeIntent=new Intent(MainActivity.this,Splash.class);
     startActivity(homeIntent);
     finish();
     }
        }, SPLASH_TIME_OUT);
   }
}

In AndroidManifest.xml,

<activity
    android:name=".SplashActivity"
    android:noHistory="true"
    android:theme="@style/Theme.AppCompat.Light.NoActionBar.FullScreen">
    <intent-filter>
        <action android:name="android.intent.action.MAIN" />

        <category android:name="android.intent.category.LAUNCHER" />
    </intent-filter>
</activity>
<activity
    android:name=".MainActivity"
    android:theme="@style/Theme.AppCompat.Light.NoActionBar.FullScreen" />

And in the splashscreen.java onCreate function, you can set up a timer to call mainactivity

new Timer().schedule(new TimerTask() {
            @Override
            public void run() {
                startActivity(new Intent(getApplicationContext(), MainActivity.class));
            }
        },4000);

Hope this helps
