Saifullah Android Using Camera
Camera is useful to capture the photos and videos in our applications. By using camera api we can control the
functionalities of camera based on our requirements.
The android framework provides a two ways such as android.hardware.camera2 api and camera intent to capture
the images and videos in our application.
By using startActivityForResult() method with intent action
parameter MediaStore.ACTION_IMAGE_CAPTURE, we can take the pictures from our android
applications.
Intent cInt = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(cInt,Image_Capture_Code);
