Question

Consider having these two codes:

Code 1:

Uri uri = Uri.parse(url);
intent.setDataAndType(uri, "audio/*");

Code 2:

intent.setDataAndType( Uri.parse(url), "audio/*");

Which one gives better performance?

Answer 1

Second one is more resource-efficient! However if you reuse the uri variable you shall go with the first one, to keep the variable persistent. The difference is pretty much minor as the snippet of code will only need few resources to run so you will not have much of a gain. Consider that the garbage collector will get the uri object as soon as it is not referenced again. All in all, pick the second if you are tight with resources, though the difference is too small to consider, but the first one gives you a reusable object, which you shall consider if you need it again.
