Answer 1

Perhaps a good way to go about looking into this is to ask how does Timely create these effects. I took a look at the APK (for educational purposes) and found this in the package ch.bitspin.timely.background:

public class BackgroundView extends FrameLayout
{
  private BackgroundGradientView a;
  private BackgroundBeamsDotsView b;
  private BackgroundCircleEffectView c;
  private BackgroundBubblesView d;

The base of the Timely animation effects are through the use of a custom View, which you can find a guide on the Android Developer website. Each of the above Views are hundreds of lines of code, but to summarize: they all utilize a background Thread that manipulates Bitmap, Paint, BitmapShader, and Canvas objects in the View's onDraw method.

I hope this helps!

Answer 2

Have a look at the live wallpaper implementations by Android itself. This is very much close to the Timely app like effect.

The sources are in packages/wallpapers/Holospiral or packages/wallpapers/PhaseBeam.

They use renderscript to implement these.
