Android: How do i display this image into a bitmap?

What i'm doing/trying to do, is. 1. Take a photo 2. Save it 3. Load/display it into a Bitmap


Opening the Built in camera application:



public void openCamera() {
Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
File file = new File(Environment.getExternalStorageDirectory()+ File.separator + "image.jpg");
takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(file));
startActivityForResult(takePictureIntent, REQUEST_IMAGE_CAPTURE);
}


onActivityResult:



protected void onActivityResult(int requestCode, int resultCode, Intent data){
//Check that request code matches ours:
if (requestCode == REQUEST_IMAGE_CAPTURE){
//Get our saved file into a bitmap object:
File file = new File(Environment.getExternalStorageDirectory()+File.separator + "image.jpg");
Bitmap image = decodeSampledBitmapFromFile(file.getAbsolutePath(), 1000, 700);
}
}


decodeSamoleBitmapFromFile:



public static Bitmap decodeSampledBitmapFromFile(String path, int reqWidth, int reqHeight)
{ // BEST QUALITY MATCH

//First decode with inJustDecodeBounds=true to check dimensions
final BitmapFactory.Options options = new BitmapFactory.Options();
options.inJustDecodeBounds = true;
BitmapFactory.decodeFile(path, options);

// Calculate inSampleSize, Raw height and width of image
final int height = options.outHeight;
final int width = options.outWidth;
options.inPreferredConfig = Bitmap.Config.RGB_565;
int inSampleSize = 1;

if (height > reqHeight)
{
inSampleSize = Math.round((float)height / (float)reqHeight);
}
int expectedWidth = width / inSampleSize;

if (expectedWidth > reqWidth)
{
//if(Math.round((float)width / (float)reqWidth) > inSampleSize) // If bigger SampSize..
inSampleSize = Math.round((float)width / (float)reqWidth);
}

options.inSampleSize = inSampleSize;

// Decode bitmap with inSampleSize set
options.inJustDecodeBounds = false;

return BitmapFactory.decodeFile(path, options);
}


I was hoping for it to load it into a bitmap. If anyone could point me in the right direction that would be very helpful!
