Unity Hub not installing Android SDK correctly?

No.

 

problem fixed here :

 

i solved. first i checked the sdk folder. and it was empty. I entered the unity hub and installed it one by one.

 

Me too! I'm on 2020.2 on windows...

 

Still happening on 2019 LTS

 

Unity Hub 2.4.3 still has an issue. When you set a install folder for your editors the android build settings are not setup correctly (2020.3.11f1 & 2021.1.10). It works fine when the install is Unity/Hub/Editors but attempting to have them on a different hard drive had this issue. (OS: Linux (Mint 19.3))

 

It works for me.

If you are facing problems with Unity Hub about installing "Unity 2020.3.11f1 / Unity 2021.1.11f1 and android modules (SDK, NDK, OpenJDK)", here's my solution :

1) Firstly, I would recommend to install "UnitySetup-Android-Support-for-Editor-2020.3.11f1.exe" to your Unity 2020.3.11f1's path or "UnitySetup-Android-Support-for-Editor-2021.1.11f1.exe" to your Unity 2021.1.11f1's path.
You'll have a folder named "AndroidPlayer" in your path "{UNITY_PATH}\2020.3.11f1\Editor\Data\PlaybackEngines\" or "{UNITY_PATH}\2021.1.11f1\Editor\Data\PlaybackEngines\".

2) In your "AndroidPlayer" folder, decompress these 3 7z files : "Android_NDK_19.0.5232133.7z", "OpenJDK_1.8.0_152.7z", "Android_SDK.7z"

3) Run Unity 2020.3.11f1 / Unity 2021.1.11f1 and go to FILE > Build settings > Platform Android, click on "switch platform"

4) You can now build your android apps in Unity 2020.3.11f1 / Unity 2021.1.11f1

 

Hello,
I am completely stumped. Whatever I do, android support will just not install via hub.

I have deleted everything (editor, hub etc) included folders and reinstalled countless times. Whatever version I use its the same thing; hub shows the tick boxes greyed not blue and just says "installed" but at build time nothing.

All the paths seem correct ( I am installing on a C: drive on a new PC).

Never had this problem before and now it is perfect and completely broken.



The only odd thing is in editor it says error "You are missing the recommended Android NDK. Install the recommended version using Unity Hub"
The paths are all correct but the NDK folder is empty.

Same issue with all Editor versions.

Any ideas?

 

The problem has been more than a year, and the developers have not solved it. Thus, Unity will never be the best. It is impossible to work with it. Excuse me.

 

Same appeared.

 

hello there. fix it by setting all pathes to previous version unity editor

 

here ohter solutions
https://stackoverflow.com/questions/56817573/cant-add-modules-to-installed-unity-editors

 

Two years, no fix, Unity indeed.

 

This issue is still happenning. Same thing on Unity Hub 3 beta.

 

Yeah it sucks. Should allow us to remove and reinstall from that menu.

 

I've found installing just the editor from Unity Hub, after it's done, install JDK, then install SDK/NDK gets rid of the error. Doing it all at once is when it fails for me.

 

I'm on Windows and this is still an issue

 

This is still an issue for me on Windows 10, Unity Hub 3.0.0-beta-5. It's been happing every time I perform another install. The current install was for Unity 2021.1.23f1.

I always get this error:

:

I have to hit Ignore to continue, but the PlatformEngines/AndroidPlayer folder has missing folders - No OpenJDK folder and missing folders inside the NDK and SDK folders.

I always keep the older version, so I can just copy across these missing folders.

Happens every time and has been happening for the last several months. It did rear its ugly head in Unity Hub 2.x and no amount of uninstalling, deleting app data folders, temp folders, rebooting, standing on one leg makes a difference.

 

I'm seeing the same issues as tnaseem on Unity Hub 3.0.0-beta-5.

If I roll back to production and install the editor that way w/Android Build support, it installs and works properly.

 

Did you manage to fix this error

 

Not much luck, I'm afraid. Although, this time it did something different.

2021.1.24f1 is out, so I gave it a shot. I selected all the modules and started the installation - This time it didn't give me any errors and stated that the installation had been completed successfully.

However, on checking the AndroidPlayer folder, I noticed that this time the OpenJDK folder was still missing. NDK and SDK folders appeared complete though.

I went back into Unity Hub and did an 'Add Module' for this version, selecting OpenJDK. But each time it would complain that it had failed some validation:



So, as before, I just copied over the OpenJDK folder from the old version into this one.

 

Yes, no errors during install, but after the process, some errors and this old friend:

 

I had the same issue with Hub beta 5 and Unity 2021.1.x
What worked for me:
1. Install just the Unity editor. Wait for it to install.
2. Add Android Support module. Wait for it to install.
3. Add SDK & NDK module. Wait for it to install.
4. Add JDK module.

 

I solved it first by installing only the editor, then by installing the android packages one at a time, all with unity hub and the editor started with administrator rights (from the properties)

 

no it didnt

 

Gave this a shot with Beta 5 when installing 2020.3.21f1, and it worked for me as well. Seems doing it sequentially like this is an effective workaround.

That said, it'd be nice if every time I 'Add Module' I didn't fail to notice it was also adding Visual Studio Community and the offline Documentation.

 

Yeah, the workaround didn't work for me. I tried a lot of different combinations of piecemeal install, but it just never could get to the point where it was happy. It also may have manifested in the inability to build to my phone (when trying to build and run, it was asking where to save, but then telling me that that file name didn't exist and wouldn't build+run). I've given up for now and am exploring different options, but hopefully they'll resolve this super old issue

 

Well damn. This problem started happening to me like in the last month.
it installs OpenJDK but not android SDK & NDK Tools
When I unclick it and click it it tries to install it. seems it downloads it but never installs it right I guess.

 

2020.3.19f1 is missing ndk too

 

Would it be fine if Unity just expose a list of sdk/ndk versions corresponding to the Unity versions so that if anything goes wrong, people could manually download and install from the android studio archive? Or provide the archive in which the sdk/ndk packages reside in so that we could manually download if needed?

 

Still Not fixed and having the same issue....its shocking such a critical thing is overlooked

 

I installed just Editor first, after it finished added modules SDK, then after it finished again added modules JDK to complete the Android part. Download them all at once was super slow and the files was corrupted somehow.
My version are Unity Hub 2.4.5 and Editor 2020.3.23.f1
The internet in my city is super slow and unstable in this Covid timeline, but it works this way (and the SDK is now updated to 30! yeah!).
(some of the comments above say they succeed this way too)
Good luck everyone.

 

Had a similar problem. The Hub (3.0.0 and prior versions too) claimed the SDK and NDK were installed while they clearly weren't. Reinstall isn't possible with the hub (missing feature!). What helped was checking the modules.json in the Unity directory and downloading the files manually. How the folders should be named is also written in the modules.json. Works now.

 

Why is it too much to ask that it just work like it's supposed to?

 

I installed unity 2022.1.8f and modules via UnityHub 3.2.0 and it keeps giving me errors with the JDK too.
Tried to completely delete the version with modules and installed it again with the same errors.
Unity Hub really should come with an easy way to remove modules seeing that the automatic module installer ofttimes does not work as intended. It is a dope feature when it does work though.

 

So I ran into this same error message on a fresh install of Unity 2021.3.8f1 on Linux.

Unity Hub installs the Android SDK, NDK, and OpenJDK into the correct location, but it strips the executable bit from all binaries, which is why the android build fails to work.

I fixed it with this workaround:

Code (csharp):

1. cd ~/Unity/Hub/Editor/2021.3.8f1/Editor/Data/PlaybackEngines/AndroidPlayer
2. for I in $(find -iname bin) ; do chmod +x "$I"/* ; done
3. chmod +x SDK/platform-tools/*
4.  

That fixed it for me on Linux. I expect the same fix would also work if this happened on Mac, since it needs the executable bits also. (I have no idea about Windows in this situation)
