global variable in onclicklistner

I am a beginner in Android development and working on a project, I am trying to access a global variable in onclick listner but i show an error. Here is Global Class

    public class GlobalClass extends Application{

private String globalUrl;

public String getGlobalUrl() {
    return globalUrl;
}

public void setGlobalUrl(String globalUrl) {
    this.globalUrl = globalUrl;
}
    }

Here its my main activity class which shows error on getApplication(), i want to use My global variables in activity class as well as simple class.

    public class MainActivity extends Activity {
Button Enter;
EditText textEdit;
TextView text;
String url;

private static String ur = "http://maps.google.com/maps/api/geocode/json?sensor=false&address=";



@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    // Calling Application class (see application tag in AndroidManifest.xml)

    textEdit   = (EditText)findViewById(R.id.postalText);
     text  = (TextView) findViewById(R.id.textViewme);
    Enter = (Button)findViewById(R.id.button_Enter);



   Enter.setOnClickListener(new View.OnClickListener(){
       public void onClick(View v){
          // Intent launchActivity = new Intent(MainActivity.this,jsonParsingActivity.class);
           Intent launchActivity = new Intent(MainActivity.this,jsonParsingActivity.class);
           startActivity(launchActivity);


           url = ur+ textEdit.getText().toString();
           ((GlobalClass) this.getApplication()).setGlobalUrl(url);
           System.out.println(url);
           Log.v(url, "extended url");

   }
   });

}

How to remove this error... thanks in advance

Just write:

MainActivity.this.getApplication()

instead of 

this.getApplication()

If you call this in your View.OnClickListener it referes to the View.OnClickListener.

Write this lines to place the value in global class variables

replace your code

((GlobalClass) this.getApplication()).setGlobalUrl(url);

with the below code

GlobalClass temp=new GlobalClass();
temp.setGlobalUrl(url);
