Question

Here’s a section of my code :

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    switch (item.getItemId()) {

    case R.id.menu_settings:

        startActivityForResult(new Intent(MainActivity.this,Settings.class),1);
        break;
    }
    return true;
}


@Override
public void onActivityResult(int requestCode,int resultCode,Intent data) {

    Toast.makeText(getBaseContext(),requestCode, Toast.LENGTH_SHORT); // This was causing the error. See the fantastic answer that's been provided for details. Comment out this this and it works !

    if(requestCode==1) {
        if(resultCode==RESULT_OK) 
        {
            String extraData=data.getData().toString();

            minD=Integer.parseInt(extraData);
            Toast.makeText(getBaseContext(),minD, Toast.LENGTH_SHORT);
        }

    }

}

Here’s the code for Settings.java

package com.example.com.draft1;

import android.app.Activity;
import android.content.Intent;
import android.net.Uri;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.Toast;



public class Settings extends Activity  {



@Override 

public void onCreate(Bundle savedInstanceState)
{

    super.onCreate(savedInstanceState);
    setContentView(R.layout.settings);


    Button setbtn = (Button) findViewById(R.id.SetminDistance);


    setbtn.setOnClickListener(new View.OnClickListener() {

        public void onClick(View v) {

        //Intent data=new Intent();
        EditText mind=(EditText) findViewById(R.id.minDistance);
                    String minDis =mind.getText().toString();
                    Intent data = new Intent();   
                    data.setData(Uri.parse(minDis));

        Toast.makeText(getBaseContext(), minDis, Toast.LENGTH_SHORT).show();
                  //  intent.putExtra("minD", minDis);





       if (getParent() == null) {
           setResult(RESULT_OK, data);
       } else {
           getParent().setResult(RESULT_OK, data);
       }
       finish();



      /*  setResult(RESULT_OK, data);
       finish();*/
            }

});

}
}

Now when I choose the menu option for Settings , the required activity opens up perfectly , however , when i attempt to return data , it leads to a force close

Here’s the Logcat reading that shows the error :

Why am i encountering a force close here ?

I’d really appreciate help here

Thanks for the interest in the question

As Per Suggestions

if(requestCode==1) {
        if(resultCode==RESULT_OK) 
        {
            //String extraData=data.getData().toString();

            //minD=Integer.parseInt(extraData);
            Toast.makeText(getBaseContext(),String.valueOf(requestCode), Toast.LENGTH_SHORT).show();
        }

Answer 1

If you see Toast.makeText

public static Toast makeText (Context context, int resId, int duration)

So if you giving second parameter as int then system will look for this id in R.java but irony is actually you wanting to print number so just cast your second parameter to String i.e. this

public static Toast makeText (Context context, CharSequence text, int duration)

Change Toast line code to

Toast.makeText(getBaseContext(),requestCode+"", Toast.LENGTH_SHORT).show();

or

Toast.makeText(getBaseContext(),String.valueOf(requestCode), Toast.LENGTH_SHORT).show();
