Unity Cloud Build

[brockw]

We are getting this error from Cloud Build but local builds work fine.

ERROR: Actionable build error: The highest installed Android API Level is 29, however version 30 is the minimum required to build for Google Play.

Is it possible the script that detects the Android API level is not working correctly? Has anyone else encountered this issue?

Hi @brockw,

Apologies for the late response. I'm not familiar with Unity's Cloud build.
Can you change the "Target API Level" to "Android 11.0 (API Level 30)" in Player Settings?

It's possible that your project has it set to "Automatic (highest installed)". That could work locally because your machine has 30 or higher installed, but fail on Cloud Build because its environment only has 29 installed.

[csonsteng]

just commenting to say that we're having the exact same problem. I've had an open ticket with Unity support for a little while, but haven't found a solution yet.

[jamcohen]

@csonsteng, is your project's "Target API Level" set to "Automatic (highest installed)" in Player Settings?

[csonsteng]

@brockw what version of Unity are you using? We're on 2020.3.4f1

[csonsteng]

@jamcohen yes it is :(

[jamcohen]

Try setting it to "Android 11.0 (API Level 30)" and seeing if that works.
My hope is that Unity's Cloud Build environment will properly download that version of the Android SDK.

[csonsteng]

@jamcohen will do! i'll let you know the result

[csonsteng]

@jamcohen i got the same error :(

124: [Unity] ERROR: Actionable build error: The highest installed Android API Level is 29, however version 30 is the minimum required to build for Google Play.
125: [Unity] Google.Android.AppBundle.Editor.Internal.BuildTools.BuildToolLogger:DisplayActionableErrorDialog (string) (at Assets/GooglePlayPlugins/com.google.android.appbundle/Editor/Scripts/Internal/BuildTools/BuildToolLogger.cs:45)

Tomorrow, i'm going to try an empty unity build with just the plugin and see if i get the same issue.

[jamcohen]

Hmm, in that case it sounds like either:

1. Unity always builds with Android 29 regardless of what is specified in Player Settings.
2. Unity downloads Android SDKs > 29 as needed, but after the plugin checks for the latest version. In which case, the plugin throws an error that the SDK isn't present, even though it will be downloaded as part of Unity's build process.

Hopefully we're dealing with 2, in which case we can add the following clause here:

var targetSdkVer = PlayerSettings.Android.targetSdkVersion;
if ((int) targetSdkVer >= MinimumVersion)
{
   return true;
}

That will skip the Android SDK version check if the Target API Level is set to something 30 or greater in Player Settings.

@csonsteng, is it possible for you to add that line, and try another Cloud Build?

Once the build succeeds, you'll want to make sure it was built with targetSdkVersion=30. Otherwise the build will be rejected by the Play Store. You can check this by opening the APK or AAB in Android Studio and checking the AndroidManifest for a <uses-sdk/> tag. Example:

<uses-sdk
        android:minSdkVersion="22"
        android:targetSdkVersion="30" />

[csonsteng]

@jamcohen we have progress! The build still failed, but now I get the following error.

125: [Unity] ERROR: Actionable build error: This build method doesn't support APK Expansion (OBB) files.
126: [Unity] Google.Android.AppBundle.Editor.Internal.BuildTools.BuildToolLogger:DisplayActionableErrorDialog (string) (at Assets/GooglePlayPlugins/com.google.android.appbundle/Editor/Scripts/Internal/BuildTools/BuildToolLogger.cs:45)

this might be something in my Unity Cloud Build config. I'll dig into it in a little bit and let you know if I find anything.

In case this ends up being a viable solution that you want to incorporate, you can wrap that code in the scripting symbol #IF UNITY_CLOUD_BUILD to make it only run on cloud builds.

[jamcohen]

That's interesting. And you're not getting that error when you build locally, right?

That error triggers if "Split Application Binary" is checked in your projects Player Settings. In older versions of Unity the checkbox is named something else, maybe "Use APK Expansion Files"? Either way, it should be the last checkbox in Player Settings -> Android -> Publishing Settings.

[csonsteng]

ahh that's a really good point. I'm not sure the last time I actually made a local build on this branch.

I did actually have that unchecked in the Player Settings, but Cloud Build's configuration overrides it with its own setting. I changed it on that end. It still failed to build.

I'll share the results in case you have any immediate thoughts, but it does seem like the original issue is resolved. I'll progress with trying and troubleshooting a local build. If I run into any struggles, I can open up a new issue.

Thank you for your help : )

@jamcohen turns out the issues were from some custom manifest stuff I had previously tried doing as a different workaround to the cloud build error.

but it works! I was able to get a successful cloud build and confirm its sdk

    <uses-sdk
        android:minSdkVersion="19"
        android:targetSdkVersion="30" />

thank you for your help!

[jamcohen]

That's great to hear! In that case, I'll close this issue once I commit that workaround.

[csonsteng]

One final note on this. This workaround also requires that "Target API Level" in Player Settings is set to "Android 11.0 (API Level 30)"

Changing it back to "Automatic (highest installed)" gives the same error even with the workaround.
