I've been running the druntime and phobos tests from the master 2.068 branch on various Android devices.  Please try out the Android test runners I just made available and report your own results in this thread:

https://github.com/joakim-noah/android/releases/tag/runners

Some output is expected and doesn't need to be reported, while any other deviations should be reported.  Please report the Android version, found in Settings->About Device->Android Version; the manufacturer; the chipset, which can be found on device databases like gsmarena; and which runners you ran.  If you google your device's name, usually the first link is the gsmarena entry.  For example, the Samsung Galaxy S6 uses the Exynos 7420:

http://www.gsmarena.com/samsung_galaxy_s6-6849.php

I'm using this ldc forum for this device reporting because it doesn't require any registration, unlike the wiki or github.  I'll collect all the results and put them on the wiki later.

All source is available to build ldc and the test runner yourself, only missing the build script I used for the apk version of the test runner.  I'll write up the build process on the wiki and push that last script into CMake next.

Expected output:

- Bionic didn't support hex format for floating point, either for literals or output, until Android 5.0.  As a result, I skip such tests in std.conv and std.format if they fail.  The command-line test runner will note that those tests were skipped on pre-5.0 Android: that's expected and only needs to be reported if it _doesn't_ happen on pre-5.0 Android.

My results:

- Android 5.1.1, Samsung, Exynos 5250: All tests pass, both command-line and apk.

- Android 5.0.2, Samsung, Exynos 5420: Std.stdio and std.socket hang in both command-line and apk, all other tests pass.

- Android 4.2.2, HTC, Tegra 3 AP37: All tests pass in the apk.  The command-line runner keeps segfaulting consistently at the same spots, not sure why since the apk runs fine, could be some aggressive process killing since this device has only 1 GB of RAM.  If I split up test.list to run only the druntime tests, the phobos tests before std.file, then the rest, ie three different runs, everything passes.

- Android 4.4.4, Sony, Snapdragon 801: All tests pass, both command-line and apk.

- Android 4.4.2, Samsung, Exynos 4412: All tests pass, both command-line and apk.

- Android 5.0.2, Samsung, Snapdragon 410: Std.stdio and std.socket hang in both command-line and apk, all other tests pass.

My LG G2 results here probably aren't as useful because it's for some random cyanogen nightly but here they are anyway:

Android 5.0.2 (CyanogenMod 12-20150304-NIGHTLY), LG, Qualcomm MSM8974 Snapdragon 800:  Std.stdio and std.socket hang in apk, all other tests pass.

Very exciting stuff.

sigh, knew I forgot to paste something.
chipset is a snapdragon 800.

Android 5.0, LG G3, Snapdragon 801:
Apk and command-line hang, one time after core.time, and the other times after std.meta.

After deletion of std.socket it hanged at std.stdio, and once these two were removed all other tests pass.

Android 5.1.1, Samsung Galaxy S6 Edge (Exynos 7420), apk all tests pass.

Awesome job!

Ran the full test suite, not all passed.

Android: v4.1.2
Device: SCH-I535 (Samsung Galaxy S3 Verizon)
Chipset: Snapdragon S4 Plus

It is rooted, FWIW.

Note that some devices (e.g. the Samsung Galaxy Note series) can use different chipsets depending on the exact model, even though they are marketed under the same product name.

All tests pass except std.datetime, both APK and CLI.

Seems to be failing on these lines:
