Wo muss dieser Code hinkopiert werden?

1Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
2 captured_image = System.currentTimeMillis() + ".jpg";
3 File file = new File(Environment.getExternalStorageDirectory(), captured_image);
4 captured_image = file.getAbsolutePath();
5 Uri outputFileUri = Uri.fromFile(file);
6 intent.putExtra(MediaStore.EXTRA_OUTPUT, outputFileUri);
7 intent.putExtra("return-data", true);
8 ((Activity) GlobalVars.main_ctx).startActivityForResult(intent, RES_IMAGE_CAPTURE);
