Screenshot of an Android application showing 3 examples of the new Brush API. From top to bottom: - 3 lines of text filled with a horizontal yellow to blue gradient. The gradient goes smoothly through green in the middle. - The same 3 lines of text, filled with a vertical cyan to magenta gradient. - A heart shape filled with a vertical gradient from yellow to red.
A screenshot of an Android application comparing gradients rendered with paint mixtures vs traditional sRGB gradients. There are 3 pages to showcase, from left to right, linear, radial, and sweep gradients. There are four rows in the first page: the first row shows an orange to red vertical gradient, with the paint mixture version on the left, sRGB on the right; the second and third row show a yellow to blue gradient, with the paint mixture on top, and the sRGB on the bottom; the fourth row shows a white to blue gradient, with the paint mixture on the left, sRGB on the right. The second page shows radial gradient comparisons as three rows. Each row has the paint mixture on the left, sRGB on the right. The gradients are, from top to bottom: yellow (center) to green (outside), magenta (center) to red, and white (center) to blue. The last page shows sweep gradients, with 3 rows (same layout as before). The gradients are from top to bottom: yellow to blue, magenta to yellow, and white to blue.

There are four rows: the first row shows an orange to red vertical gradient, with the paint mixture version on the left, sRGB on the right. The second and third rows show a horizontal yellow to blue gradient: the top one is a paint mixture, the bottom one is traditional sRGB. The paint mixture version shows that the gradient becomes green in the middle. The last row compares a white to blue vertical gradient, with a paint mixture on left, and tradition sRGB on the right. The paint mixture version show a blue becoming brighter/lighter, whereas the traditional version becomes purple.
Two Kotlin functions that take 2 float parameters a and b. Each function returns a divided by b if b is not 0, or a constant called DefaultValue otherwise. The first function does so using takeIf, let, and the "elvis" operator. The second function uses a simple if/else statement.
Kotlin method called indexOf that performs a linear search of a specified value inside an array called elements. The number of entries in the array is tracked by a property called size. The linear search is a for loop from 0 until size.
