How do I access the camera on Android phones?

Question

I\'ve written a program in Java that takes in an image file and manipulates the image. Now I\'m trying to access the camera so that I can take the photo and give it to the image

Answer 1

there are many ways by which u can do this.... One of the better way which i think is the short and simple is to on Button Click u can call intent which opens ur inbuilt camera view... here is the sample code...

public class CameraDemo extends Activity {

Button ButtonClick;
int CAMERA_PIC_REQUEST = 2; 
int  TAKE_PICTURE=0;
Camera camera;


/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    ButtonClick =(Button) findViewById(R.id.Camera);
    ButtonClick.setOnClickListener(new OnClickListener (){
        @Override
        public void onClick(View view)
        {
            Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
            startActivityForResult(cameraIntent, CAMERA_PIC_REQUEST);
        }
    });        
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) 
{
    super.onActivityResult(requestCode, resultCode, data);
    if( requestCode == CAMERA_PIC_REQUEST)
    {   
        Bitmap thumbnail = (Bitmap) data.getExtras().get("data");
        ImageView image =(ImageView) findViewById(R.id.PhotoCaptured);
        image.setImageBitmap(thumbnail);
    }
    else 
    {
        Toast.makeText(demo.this, "Picture NOt taken", Toast.LENGTH_LONG);
    }

}
}
