I’ve been developing on PC (but on OSX now for the tl;dr-inclined folks) for awhile now. I’ve been with UE4 since 4.0; I am very familiar by now with packaging to Android and iOS and the setup involved, dev or distribution. I’ve always used an old Macbook Pro for building to iOS, as cumbersome as that is (it barely opened the engine).
So I’ve now switched to a Mac Pro for all dev work and building to Android/iOS. All-in-one, baby.
But,
After installing Java and AndroidWorks, I get the wonderful “You are missing some required components for Android game creation.” message. I made sure to follow the Quick Start guide like 3 extra times and did a bunch of uninstalling/reinstalling/restarting/crying to no avail.
Running 4.10.4. Built to iOS just fine. Editor recognizes Android devices in Project Launcher but obviously fails to build there.
Fresh installation did nothing. Should I try actually purging all UE4 and AndroidWorks files and starting from scratch? Also, does it matter that the project has code as far as packaging to Android from OSX is concerned?
It’s worth a shot to get rid of all the Android-related files and run through the setup again just to ensure that something didn’t go wrong when it was set up the first time.
Did you try to build the code project for Development/Shipping Android before attempting to package?

Turns out the solution was specific to my situation, so not sure if it’ll help many people. But here it is:
I’m using Photon for realtime networking on mobile. For UE4.10+ and Photon 4+ to work together, I needed to use an Android NDK that pre-dated the current version of r11c that gets installed when setting up AndroidWorks. When using r10b or r10e (the easiest ones to find for Mac for some reason), it messes up. Using r10d, however, solved the problem and allowed me to build for Android on OSX. That version was “just right”, and seems to allow building to Android from both Windows and OS X.
If you download r10d for Mac from here: http://pnsurez.blogspot.com/2015/07/download-android-ndk-tools.html and get a finicky .bin file, just remove the extension in the name and click the resulting .exe. It’ll extract the files into your user folder. Move it over to NVPACK (for organizational purposes), and point to it in your NDK selection within Project Settings > AndroidSDK.
Hit the same issue. All the answers so far have been specific to individual solutions, so I had to track down a little further. Spreading the steps around for later searchers.
The sdk setup validation is done via UnrealBuildTool, executed from TargetPlatformManagerModule.cpp :: SetupSDKStatus()
You can iterate a little faster than through the editor: run /Engine/Binaries/DotNET/UnrealBuildTool.exe -validateplatform -platforms=Android
you can add -verbose, but it doesn’t actually print anything useful.
In your IDE, set UnrealBuildTool as the startup project, set the parameters above for launch, and add a breakpoint in UEBuildAndroid.cs :: HasAnySDK()
step through, and you can see what values are actually being used for the validation step, and what it is expecting / what it can’t find.
Epic: it would be nice if -verbose actually printed something useful in this situation.
