Avoid using JPG images during Android Development

Due to the fact that jpgcontent is easy to use, the use of .jpg images should be as full as possible in androiddevelopment, and the use of .png images, it uses a lossless data compression algorithm derived from LZ77.

In fact, Google has already hinted at us:

No. In res, these icons are all in png format. That is to say, Google recommends png images.

This reminds me of a small matter. My shoes asked: how can I standardize the layout file corresponding to an Activity.

In fact, when we create an Activity, we can also see some clues:

If you create a MainActivity, the default layout file name is activity_main.
Such a name is also relatively standard and recommended.

Even when we encounter a small thing that is not sure how to do it, let's take a look at Google's own method.
