Jason A. Donenfeld f4fc15538d tv: hack gridlayoutmanager to fill columns before row if we're not scrolling
If we're horizontally scrolling, it makes sense to fill rows before
columns. But if it all fits in one page and we don't need to scroll
horizontally, it looks ridiculous. So, in this case, rearrange the tiles
so that it appears to fill columns before rows. But we don't want things
suddenly jumping around, so actually, keep the same ordering as
rows-before-columns, but add invisible spaces after certain items, so
that the fill area makes it look as though it's columns-before-rows.
This winds up being much more visually pleasing.

We do this by figuring out this kind of transformation:

If we convert this matrix:

	0 3 6
	1 4 _
	2 5 _

To this one:

	0 2 4 6
	1 3 5 _
	_ _ _ _

For a given index, how many spaces are under it? This changes depending
on how many total are in a grid. Going from 3x3 to 4x3, for example, we
have:

	count == 12, index =
	count == 11, index = 10
	count == 10, index = 7,9
	count == 9, index = 4,6,8
	count == 8, index = 1,3,5,7
	count == 7, index = 1,3,5,6!
	count == 6, index = 1,3,4!,5!
	count == 5, index = 1,2!,3!,4!
	count == 4, index = 0!,1!,2!,3!
	count == 3, index = 0!,1!,2!
	count == 2, index = 0!,1!
	count == 1, index = 0!
	count == 0, index =

The '!' means two blanks below, no '!' means one blank below, and no
mention means no blanks below.

This commit adds code to compute such a table on the fly.

Android GUI for WireGuard

Download from the Play Store

This is an Android GUI for WireGuard. It opportunistically uses the kernel implementation, and falls back to using the non-root userspace implementation.

Building

$ git clone --recurse-submodules https://git.zx2c4.com/wireguard-android
$ cd wireguard-android
$ ./gradlew assembleRelease

macOS users may need flock(1).

Embedding

The tunnel library is on JCenter, alongside extensive class library documentation.

implementation 'com.wireguard.android:tunnel:$wireguardTunnelVersion'

The library makes use of Java 8 features, so be sure to support those in your gradle configuration:

compileOptions {
    sourceCompatibility JavaVersion.VERSION_1_8
    targetCompatibility JavaVersion.VERSION_1_8
}

Translating

Please help us translate the app into several languages on our translation platform.
