Picking an Image and Taking Photo in Android – Java source code

This is Java source code for Android, providing you with two functions: to take a photo using camera and to pick an image from gallery.

//bitmap variable
Bitmap bitmap;

//function to take photo
public void takeAPhoto(){
	Intent takePic = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
	startActivityForResult(takePic, 0);
}

//function to pick an image from gallery
public void pickAnImage(){
	Intent pickedImage = new Intent(MediaStore.ACTION_GET_CONTENT);
	startActivityForResult(pickedImage, 1);
}

//receiving taken photo and assign bitmap variable with it
@Override
protected void onActivityResult(int RC, int RQC, Intent I) {
	super.onActivityResult(RC, RQC, I);
	//if a photo has been taken
	if(RC == 0 && RQC == RESULT_OK){
		Uri uri = I.getData();
		try {
			bitmap = MediaStore.Images.Media.getBitmap(getContentResolver(), uri);
		} catch (IOException e) {
			e.printStackTrace();
		}
	}
	//if an image has been picked
	if(RC == 1 && RQC == RESULT_OK){
		Uri uri = I.getData();
		try {
			bitmap = MediaStore.Images.Media.getBitmap(getContentResolver(), uri);
		} catch (IOException e) {
			e.printStackTrace();
		}
	}
}
