Unity 2018 still has problems listing target platforms?

Hey guys,

We recently upgraded from Unity 5.5.2p2 to Unity 2018.1.3f1. For the longest time we had issues building to android where we would see errors like this:


The solution was always this odd fix to install downgraded SDK tools here:
http://dl-ssl.google.com/android/repository/tools_r25.2.5-windows.zip

We assumed that this issue was something specific to our old build but it seems this is still an issue in 2018? Can anyone shed some light on this? Are we doing something wrong or is this really still an issue?

I noticed in the SDK manager there are several new versions of the Build-Tools well ahead of 25.2.5 but if we try any of them our game won't build.

Here are a few specific questions we could really use some clarity on:
1. Do we really need to downgrade the tools to 25.2.5 or is there another work around to fix this issue?

2. How do each of these different packages found in the Android Studio > Android SDK manager impact builds in Unity? It seems like we can use a current API level like Oreo (API Level 27), but the Build Tools need to be downgraded or Unity won't publish. Each of these components seems to have a different version number and it's unclear exactly how they impact our builds within Unity, we could really use some clarity on these:
- Android API
- Android SDK Build-Tools (which opens to show many versions inside)
- Android SDK Platform-Tools
- Android SDK Tools






Here is Android SDK Build-Tools 28 expanded:

 

In addition to having to downgrade the Android SDK Build-Tools to 25.2.5... it seems like in Unity 2018 the adaptive icon window isn't recognizing that we do have a modern Android API installed. As you can see we receive these icon warnings even after installing API levels 26, 27 + 28.

Any help understanding whats up here would be super helpful, thank you!

 

Is there any plan to support the new version of Android SDK Tool for unity?

 

Hmmm, my intention was to include a screenshot there, not sure what happened in the upload, but here is the warning regarding adaptive icons, (I assume you can see my other screenshots?)

I have API Level 27 currently installed, so this makes no sense

And yes I have jdk8 installed


I've tried tons of combinations and none of them work unless I download the old build tools 25.2.5.
This has been a confirmed issue in the past:
https://issuetracker.unity3d.com/is...-android-sdk-tools-25-dot-3-1-version-is-used

Still receiving same error message:
"Unable to list target platforms..."

 

Are you experiencing the same problem when attempting to build with the latest SDK tools?

 

Interestingly, I uninstalled jdk9 (which was installed on my computer but was not referenced by Unity) and the builds now work. To be clear, the Unity Preferences > External Tools > JDK value was set to use jdk 1.8 the entire time... not sure why this worked, but thanks.

 

Hello,

I found this thread because of the "Required API level 26" error too, and it's getting annoying... I'll post some info below so if anyone is looking to find an answer can compare situations and figure out the solution

This is the initial error https://ibb.co/BPfrhb7, and when I click on, and when I click on update Android SDK, it shows me a message that says "Unable to install additional SDK platform. Please make the SDK manager manually to make sure you have the latest set of tools...."

Also, selected the Target API Level under "Other Settings" to be the correspondent https://ibb.co/Ypg3nfq nevertheless, when I tried to build the APK for testing, it still shows me the initial message.

Then I tried the old solution of replacing the existing tools file with the "tools_r25.2.5-windows" package, but when I try to build with that file replaced within the skd file it shows a message saying thet the "Android SDK is Outdated" https://ibb.co/QYJXkCZ

So now am kind of confused, but when checking on my console error I get this as the error:

UnityException: Required API level 26.

I checked Android Studio I made sure that the API 26 was installed, and in theory is there but when trying to use Unity with the available tools it keeps showing an error https://ibb.co/hBg0XZg

Any suggestions to solve this would be appreciated.

 

Hi, @JuliusM

I'm using Unity 2018.3.8f1, within the External Tools sections I kept selected the "Use Embedded JDK" option, because when I tried to used the path to the C: installation I got another error. So was I did was trying to use the unity SDK that comes with the package, then it asked me to use API level 26 and I download that version through the SDK manager.

After that I tried to build but it shown me an error saying "sdk tools is outdated version 0.0.0 < 23.0.0", so I decided the use a legacy tooks pack downloaded from the net and replace that pack into the sdk file. Then I tried to build again and I'm having the "Failed sign to SDK" again...

So in summary, if I used the C path to the SDK it creates an error and if I select using the embedded SKD version it also creaste and error.... However I checked errors console and it shows a warning saying:

"Failed getting available Android API levels. Make sure your android sdk tools version is 25 or higher and you have internet connection."

Of couse I have internet connection, but looks like there's some kind of trouble in the communication between the SDK Tools and the keystore or something like that... here are the errors I'm having

 

pls help .....i have uninstalled jdk 11.....but still getting this error...target api set on 28

Build settings -> player settings -> other settings -> in target API level I selected the highest. It was't selected the highest. This solved the problem for me

 

Hi can any one help me ?

I am using Unity 2019.2.0f1 and jk 8, the problem is that, during build this error comes that sdk tools version
25.2.5 < 26.1.1 which is in my screenshot _1. when i go to my sdk manager there i see only sdk tools version 25.2.5 and nothing about 26.1.1 which is in my screenshot_2 while my build settings are in screenshot_3.

kindly help to solve this problem.

thanks.

 

thanks JuliusM,
i am very thankfull to you. my problem is solved becouse of you. again thanks

 

I have been searching for this all over the unity forums and unity answers but could not find an explanation to this warning. Can any one explain this to me?

I am getting this warning in Unity. I am testing the game on Android API 28 and it is working fine but still I am not sure if this is some thing to worry. I am setting Minimum API Level to 16 and Maximum to "Automatic Highest Installed" and I am having API 16 to API 29 installed in SDK Manager in Android Studio tools. Also I am having internet connection active. I am using Unity 2018.4.10f1

"Failed getting available Android API levels. Make sure your android sdk tools version is 25 or higher and you have internet connection."

I tried various things but no success.

 

Thanks JuliusM. I tried using 2018.4.23f1 LTS which is latest available 2018LTS version under unity hub. But still I got the same error. I tried opening different projects in 2018 different versions but same issue persists. I have SDK platforms from API 16 to API 30 and SDK build tools also from 16 to 30 in SDK manager. However After setting Minimum API Level to API 19, I don't get this warning all the time. I now get only few and far between along with below error some times.

"IndexOutOfRangeException: Index was outside the bounds of the array. UnityEditor.Android.AndroidBuildWindowExtension.GetBuildPlayerWindow () (at <df45ca7b334d4b918976307f9d26db2e>:0) UnityEditor.Android.AndroidBuildWindowExtension.RepaintTargetList () (at <df45ca7b334d4b918976307f9d26db2e>:0) UnityEditor.EditorApplication.Internal_CallUpdateFunctions () (at C:/buildslave/unity/build/Editor/Mono/EditorApplication.cs:200)"

But my apk runs perfect on API 28 I am testing against. If my apk is not causing problem to me, then are these warnings and errors something to worry?
