Unable to implement back button in Actionbar

i am creating a application with ActionBar. in which action bar performing sharing action. but i want to add the back button along with the sharing implementation. Basically i want both things to work as per the user selection.

here is my code:

@Override
    public boolean onOptionsItemSelected(MenuItem item) {

        switch (item.getItemId()) {
        case android.R.id.home:
            // app icon in action bar clicked; go home
            Intent intent = new Intent(this, MainActivity.class);
            intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
            startActivity(intent);
            return true;
        default:
            return super.onOptionsItemSelected(item);
    }

        // Handle item selection
        ImageView image = (ImageView) findViewById(R.id.full_image_view); //Unreachable Code
        Bitmap bitmap = ((BitmapDrawable)image.getDrawable()).getBitmap();

        File sd = Environment.getExternalStorageDirectory();
        String fileName = "desi.png";
        File dest = new File(sd, fileName);
        try {
            FileOutputStream out;
            out = new FileOutputStream(dest);
            bitmap.compress(Bitmap.CompressFormat.PNG, 100, out);
            out.flush();
            out.close();
        } catch (FileNotFoundException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        switch (item.getItemId()) {
            case R.id.item:
                Uri uri = Uri.fromFile(dest);
                Intent shareIntent = new Intent();
                shareIntent.setAction(Intent.ACTION_SEND);
                shareIntent.putExtra(Intent.EXTRA_STREAM, uri);
                shareIntent.setType("image/*");
                startActivity(Intent.createChooser(shareIntent, getResources().getText(R.string.share)));
                return true;
            default:
                return super.onOptionsItemSelected(item);
        }

    }

i myself implemented both things but ended with unreachable code as eclipse mentioned to me. any help will be appreciated. Thank You!

this is the correct code:

switch (item.getItemId()) {
            case R.id.item:
                Uri uri = Uri.fromFile(dest);
                Intent shareIntent = new Intent();
                shareIntent.setAction(Intent.ACTION_SEND);
                shareIntent.putExtra(Intent.EXTRA_STREAM, uri);
                shareIntent.setType("image/*");
                startActivity(Intent.createChooser(shareIntent, getResources().getText(R.string.share)));
                return true;


            case android.R.id.home:
                // app icon in action bar clicked; go home
                Intent intent = new Intent(this, MainActivity.class);
                intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
                startActivity(intent);
                return true;
            default:
                return super.onOptionsItemSelected(item);
        }

i tried to implement both case in single switch statement and this removes the error and plus the app is working according to the code. Thank You!
