            </activity>
        </application>
    
    </manifest>

   
MainActivity:
    
    
    package com.example.helloworld;
    
    import android.os.Bundle;
    import android.view.View;
    import android.widget.Button;
    import android.widget.TextView;
    import android.app.Activity;
    
    public class MainActivity extends Activity {
    
    	int counter;
    	Button add, sub;
    	TextView display;
    
    	@Override
    	public void onCreate(Bundle savedInstanceState) {
    		super.onCreate(savedInstanceState);
    		setContentView(R.layout.activity_main);
    		counter = 0;
    		add = (Button) findViewById(R.id.bAdd);
    		sub = (Button) findViewById(R.id.bSub);
    		display = (TextView) findViewById(R.id.tvDisplay);
    		add.setOnClickListener(new View.OnClickListener() {
    			
    			public void onClick(View v) {
    				
    				counter++;
    				display.setText("Your Total is " + counter);
    			}
    		});
    		sub.setOnClickListener(new View.OnClickListener() {
    			
    			public void onClick(View v) {
    				
    				counter--;
    				display.setText("Your Total is " + counter);
    			}

    public class Splash extends Activity{
    
    	@Override
    	protected void onCreate(Bundle savedInstanceState) {
    		// TODO Auto-generated method stub
    		
    		super.onCreate(savedInstanceState);
    		setContentView(R.layout.splash);
    		Thread timer = new Thread(){
    			public void run(){
    				try{
    					sleep(5000);
    					
    				} catch (InterruptedException e){
    					e.printStackTrace();
    				}finally{
    					Intent openStartingPoint = new Intent("com.example.helloworld.MAINACTIVITY");
    					startActivity(openStartingPoint);
    				}
    			}
    		};
