How to install a custom Android boot animation

There are two methods to do this -- using a dedicated app, or learning how to do it manually, which isn't at all hard. We'll show you both, though it's best you learn to do it manually, as while that leaves room for error, you'll have wider range of choice. Just make sure to keep this in mind: your phone's pixel density is the deciding factor when picking between the different boot animation sizes. Oh, and you need to be rooted, obviously. On most modern devices, you're looking for HDPI/XHDPI (sometimes these are simplified to an exact resolution for simplicity), but do your research before loading a boot animation that isn't suited for your device.
