Do you want to customize the little animation that starts automatically when Android starts? You do not know how ? Let customization enthusiasts be reassured, we will see right away how to customize the boot animation of an Android smartphone and replace your old boot animation with a video sequence corresponding to your tastes..
What is a boot animation?
Everyone knows how to change the background image of the Android desktop or change the appearance of application icons. But few are the owners of Android smartphones to install a new boot animation also called boot animation .
But by the way, what is a boot animation? Behind this barbaric name hides in fact the small animated sequence which appears on the screen of your smartphone when it starts up. For those who still don't know what I'm talking about, I invite you to turn your smartphone off and then on again..
When the phone starts, you will see a small logo animation appear. This varies depending on the make and model of your smartphone. It can be a 3D animation of the logo of the manufacturer of your device (or your telephone operator) and sometimes even bugdroid, the little green robot, the official mascot of Android for several years.
Where to find boot animations?
Animations are in fashion at the moment. As proof, the success of sites like Giphy or Tumblr on which Internet users come to see or recover small animated sequences in the form of Gif files. Some of you may be tempted to import an animated GIF on your smartphone in the hope of transforming it into boot animation. No need to try, it will not work..
The boot animation is in the form of an uncompressed ZIP archive containing all the images of the animation as well as a text file explaining to the Android system in what order they should be displayed. Obviously nothing prevents you from creating your boot animation yourself, but admit it the exercise is far from easy.
Fortunately, there are many sites on the net offering boot animations already made. You just have to make sure before installing them on your smartphone that they correspond to the resolution of your screen. Otherwise you may end up with a totally distorted or pixelated animation.
