            startActivityForResult(intent, CAMERA_REQUEST);

        }
    });

You are getting wrong because you are doing it wrong way.

If you pass the extra parameter MediaStore.EXTRA_OUTPUT with the camera intent then camera activity will write the captured image to that path and it will not return the bitmap in the onActivityResult method.

If you will check the path which you are passing then you will know that actually camera had write the captured file in that path.

I was facing same problem but fixed using following code ,

 Write folllowing code before `onCreate()`

 File output;

Write Following code inside onClickListner

 Intent i = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
 File dir = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DCIM);
 output = new File(dir, "CameraContentDemo.jpeg");
 i.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(output));
 startActivityForResult(i, 1);

Inside onActivityResult

 @Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {

    if (requestCode == 1) {
        if (resultCode == RESULT_OK) {
           imgUpload.setImageURI(Uri.fromFile(output));
         }
}
