java - Using the camera activity in Android

Question

If you want to use the built-in camera activity which uses the native Android camera, simply do the following.

Intent camera = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);   
        this.startActivityForResult(camera, PICTURE_RESULT);

You want to get the images back from the nifty camera you displayed -- but how?

Answer 1

If you want to get the image back in its full glory, pass in a uri to the Intent within the EXTRA_OUTPUT extra. If you're fine with a smallish bitmap (and you should be), just call the intent as normal.

Now you have two options, deal with the uri of the image that is returned in the EXTRA_OUTPUT extra, or do the following in your onActivityResult method:

if (requestCode == PICTURE_RESULT) //
             if (resultCode == Activity.RESULT_OK) {
                // Display image received on the view
                 Bundle b = data.getExtras(); // Kept as a Bundle to check for other things in my actual code
                 Bitmap pic = (Bitmap) b.get("data");

                 if (pic != null) { // Display your image in an ImageView in your layout (if you want to test it)
                     pictureHolder = (ImageView) this.findViewById(R.id.IMAGE);
                     pictureHolder.setImageBitmap(pic);
                     pictureHolder.invalidate();
                 }
             }
             else if (resultCode == Activity.RESULT_CANCELED) {...}
    }

And there you go!
