Several years ago, Google introduced the WebP image format. This will substantially reduce the size of those images. In that case, you do not need a 20-megapixel photo - you could safely reduce the resolution to be a few hundred pixels on a side, rather than a few thousand. For example, it may be that you only ever show the image as a thumbnail. Moreover, you may not need all of that resolution. Modern cameras offer very high resolution, and high-resolution photos take up a lot of disk space. The biggest bitmaps of all tend to be photographs. However, do not try swapping your launcher icon mipmap with a vector drawable, as not all launcher apps are set up to handle that.

Replacing several bitmaps with a single vector drawable should result in a substantial reduction in your APK size. With bitmaps, you might have multiple images in multiple drawable directories (e.g., res/drawable-hdpi/, res/drawable-xhdpi/). And a vector drawable is density-independent, so you only need one such drawable to get good results on all screen densities. If that drawable looks good, you can remove the bitmaps.Ī vector drawable on its own typically is smaller than an equivalent PNG file. If the graphic designer can supply you with an SVG image instead, you can use the Vector Asset wizard to try converting that SVG to a vector drawable.
You may be able to replace some of those bitmaps with vector drawables, the ones we used in this book for toolbar button icons.įor example, you may get bitmaps to put in your app from a graphic designer. If you can remove some - such as through the techniques in the preceding sections - that is great! For those that remain, though, you still have some options for making them take less space than they do presently. Typically, your largest resources are bitmaps: PNGs, JPEGs, etc.
