// Calling activity
    
    package com.example.androidtutorial2;
    
    import android.os.Bundle;
    import android.app.Activity;
    import android.content.Intent;
    import android.view.Menu;
    import android.view.View;
    import android.view.View.OnClickListener;
    import android.widget.Button;
    import android.widget.EditText;
    import android.text.InputType;
    
    public class MainActivity extends Activity {
    
        @Override
        public void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_main);
            
            //EDIT TEXT
            final EditText sharedata = (EditText) findViewById ( R.id.editText1 ) ;
            sharedata.setInputType(InputType.TYPE_CLASS_NUMBER | InputType.TYPE_NUMBER_FLAG_DECIMAL | InputType.TYPE_NUMBER_FLAG_SIGNED);
            
            //BUTTON
            Button sendbutton = (Button) findViewById (R.id.button2) ;
            sendbutton.setOnClickListener(new OnClickListener() {
    			
    			@Override
    			public void onClick(View v) {
    				
    				int edittext_data =                     Integer.valueOf(sharedata.getText().toString());
    				
    				Intent sendintent = new Intent(MainActivity.this,second_activity.class);
    				sendintent.putExtra("somedata", edittext_data);
    				startActivity(sendintent);
    				
    			}
    		});
            
    //        Button button_to_call_activity = (Button) findViewById(R.id.button1);
    //        button_to_call_activity.setOnClickListener(new OnClickListener() {
    //			
    //			@Override
    //			public void onClick(View v) {
    //			
    //				
    //			}
    //		});
           
        }
    
        @Override
        public boolean onCreateOptionsMenu(Menu menu) {
            getMenuInflater().inflate(R.menu.activity_main, menu);
            return true;
        }
    
        
    }
    
    
    //CALLED ACTIVITY
    
    
    
    package com.example.androidtutorial2;
    
    import android.app.Activity;
    import android.content.Intent;
    import android.os.Bundle;
    import android.text.InputType;
    import android.widget.EditText;
    
    public class second_activity extends Activity {
    	
    	public void onCreate(Bundle savedInstanceState) {
    		super.onCreate(savedInstanceState);
    		setContentView(R.layout.activity_second);
    		
    		EditText displaymessage = (EditText) findViewById ( R.id.editText1 );
    		
    		Intent intent1 = getIntent();
    		Bundle bundle1 = intent1.getExtras();
    		int integer1 = bundle1.getInt("somedata");
    		
    		Integer string1 = integer1;
    		
    		displaymessage.setText(integer1);               // HERE IS A RUNTIME ERROR
    		
    	
    	}
    }
