Android 9 Development Cookbook - Third Edition

How it works...

There are two parts to working with the default camera app. The first is to set up the Intent to launch the app. We create the Intent using MediaStore.ACTION_IMAGE_CAPTURE to indicate we want a photo app. We verify a default app exists by checking the results from resolveActivity(). As long as it's not null, we know an application is available to handle the Intent. (Otherwise, our app will crash.) We create a filename and add it to the Intent with putExtra(MediaStore.EXTRA_OUTPUT, mLastPhotoURI).

When we get the callback in onActivityResult(), we first make sure it's PHOTO_RESULT and RESULT_OK (the user could have cancelled), then we load the photo in ImageView.
