Capture the image and save it to SD card in a new folder

I call the camera and capture the images, I will have to record 10 images one by one and store them on the SD card before I can set them as an image. Please check my code below, it is not set to image.

How can I save it to SD card and get it to set the image? How can I name the images before saving?

In the first activity, I call the camera:

protected void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    mContext = this;
    init();
}

private void init() {
    String extStorageDirectory = Environment.getExternalStorageDirectory()
            + "/testing";

    File xmlDirectory = new File(extStorageDirectory);
    if (!xmlDirectory.exists())
        xmlDirectory.mkdirs();

    iv1 = (ImageView) findViewById(R.id.iv1);
}

private OnClickListener onBtnClicked = new OnClickListener() {
    @Override
    public void onClick(View v) {
        // TODO Auto-generated method stub
        switch (v.getId()) {
            case PHOTO:
                Intent selectImageIntent = new Intent(first.this,
                        second.class);
                startActivityForResult(selectImageIntent, 1);
                break;
        }
    }
};

protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (requestCode == 1) {
        if (resultCode == RESULT_OK) {
            String result = data.getStringExtra("result");

            Log.d("*****************",
                    "inside onactivityresult in main activity=" + result);

            Bitmap bitmap = BitmapFactory.decodeFile(result);
            iv1.setImageBitmap(bitmap);
            iv1.setScaleType(ScaleType.FIT_XY);
        }
    }
}

      

        
        
        
      

    

And in my second activity, I grab the image and pass it to the first activity:

private void init() {
    picturePath = Environment.getExternalStorageDirectory() + "/Camera/"
            + "test.jpg";
    System.out.println("thumbnail path~~~~~~" + picturePath);
    File file = new File(picturePath);
    outputFileUri = Uri.fromFile(file);
}


public void startCamera() {
    Intent intent = new Intent(
            android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
    intent.putExtra(MediaStore.EXTRA_OUTPUT, outputFileUri);
    startActivityForResult(intent, IMAGE_CAPTURE);
}

protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (requestCode == IMAGE_CAPTURE) {
        if (resultCode == RESULT_OK) {
            Intent returnIntent = new Intent();
            returnIntent.putExtra("result", picturePath);
            setResult(RESULT_OK, returnIntent);
            finish();
        }
    }
}
