Question

the program doesnt call onActivityResult, ive been in many post as this but i cant make it work.

Im using Android 3.0 Emulator.

this is the code of GameScreen.java

@Override 
public void onActivityResult(int requestCode, int resultCode, Intent data) {      
  super.onActivityResult(requestCode, resultCode, data); 
  switch(requestCode) { 
    case 0: { 
      if (resultCode == Activity.RESULT_OK) {    
          String newText = data.getStringExtra("isRunning");          
          // TODO Update your TextView.
          isRunning = true;
      } 
      break; 
    } 
  } 
}
 public void pause(){
    clickListener = new OnClickListener() {         
        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub              
            pause.setImageResource(R.drawable.pauseafter);
            isRunning = false;
            Intent intent = new Intent(Gamescreen.this, Shop.class);                  
            startActivityForResult(intent, 0);
        }
    };
}

this is the code Shop.java

public void returnButton(){
    resume.setOnClickListener(new OnClickListener() {           
        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub
            Intent intent = new Intent();
            setResult(Activity.RESULT_OK,intent);
            finish();
        }
    });
}

To test I’ve created simple application. Nothing fancy, just default layout and two activities. Toast in onActivityResult is shown properly.

Here’s complete working code:

file OnReturnActivity.java:

package some.package;

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.widget.Toast;

public class OnReturnActivity extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        Intent i = new Intent(this, GimmeReturn.class);
        startActivityForResult(i, 0);
    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        // TODO Auto-generated method stub
        Toast.makeText(this, "Got Result " + String.valueOf(resultCode),     Toast.LENGTH_SHORT).show();
        super.onActivityResult(requestCode, resultCode, data);
    }
}

file GimmeReturn.java:

package some.package;

import android.app.Activity;
import android.os.Bundle;

public class GimmeReturn extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        Toast.makeText(this, "Returning!", Toast.LENGTH_SHORT).show();
        setResult(RESULT_OK);
        finish();
    }
}

Both activities need to be added to Android manifest. Activity OnReturnActivity has action MAIN and category LAUNCHER (and is started as main activity for application). Activity GimmeResult is just added without any IntentFilter.
