Couldn't build Android App

Question

Hi Folks,

I'm trying to build a little test App for Android. But currently I can't build Android apps cause of t$$anonymous$$s error.

"CommandInvokationFailure: Unable to list target platforms. Please make sure the android sdk path is correct. C:/Users/patri/AppData/Local/Android/sdk\tools\bin\avdmanager.bat list target -c stderr[ Exception in thread "main" java.lang.NoClassDefFoundError: javax/xml/bind/annotation/XmlSchema at com.android.repository.api.SchemaModule$SchemaModuleVersion.(SchemaModule.java:156) at com.android.repository.api.SchemaModule.(SchemaModule.java:75) at com.android.sdklib.repository.AndroidSdkHandler.(AndroidSdkHandler.java:81) at com.android.sdklib.tool.AvdManagerCli.run(AvdManagerCli.java:213) at com.android.sdklib.tool.AvdManagerCli.main(AvdManagerCli.java:200) Caused by: java.lang.ClassNotFoundException: javax.xml.bind.annotation.XmlSchema at java.base/jdk.internal.loader.BuiltinClassLoader.loadClass(BuiltinClassLoader.java:582) at java.base/jdk.internal.loader.ClassLoaders$AppClassLoader.loadClass(ClassLoaders.java:185) at java.base/java.lang.ClassLoader.loadClass(ClassLoader.java:496) ... 5 more ] stdout[ ] exit code: 1 UnityEditor.Android.Command.WaitForProgramToRun (UnityEditor.Utils.Program p, UnityEditor.Android.WaitingForProcessToExit waitingForProcessToExit, System.String errorMsg) UnityEditor.Android.Command.Run (System.Diagnostics.ProcessStartInfo psi, UnityEditor.Android.WaitingForProcessToExit waitingForProcessToExit, System.String errorMsg) UnityEditor.Android.AndroidSDKTools.RunAndroidSdkTool (System.String toolName, System.String arguments, Boolean updateCommand, UnityEditor.Android.WaitingForProcessToExit waitingForProcessToExit, System.String errorMsg) UnityEditor.Android.AndroidSDKTools.ListTargetPlatforms (UnityEditor.Android.WaitingForProcessToExit waitingForProcessToExit) UnityEditor.Android.AndroidSDKTools.GetTopAndroidPlatformAvailable (UnityEditor.Android.WaitingForProcessToExit waitingForProcessToExit) UnityEditor.Android.PostProcessor.Tasks.CheckAndroidSDK+SDKPlatformDetector.GetVersion (UnityEditor.Android.AndroidSDKTools sdkTools) UnityEditor.Android.PostProcessor.Tasks.CheckAndroidSDK+SDKComponentDetector.Detect (UnityEditor.Android.AndroidSDKTools sdkTools, System.Version minVersion, UnityEditor.Android.PostProcessor.ProgressHandler onProgress) UnityEditor.Android.PostProcessor.Tasks.CheckAndroidSDK.EnsureSDKComponentVersion (System.Version minVersion, UnityEditor.Android.PostProcessor.Tasks.SDKComponentDetector detector) UnityEditor.Android.PostProcessor.Tasks.CheckAndroidSDK.EnsureSDKComponentVersion (Int32 minVersion, UnityEditor.Android.PostProcessor.Tasks.SDKComponentDetector detector) UnityEditor.Android.PostProcessor.Tasks.CheckAndroidSDK.Execute (UnityEditor.Android.PostProcessor.PostProcessorContext context) UnityEditor.Android.PostProcessor.PostProcessRunner.RunAllTasks (UnityEditor.Android.PostProcessor.PostProcessorContext context) UnityEngine.GUIUtility:ProcessEvent(Int32, IntPtr)"

Does anyone has a idea what's causing t$$anonymous$$s issue?

I'm using Unity 2017.3 and tle latest Installation/Updates of Android Studio

NDK: "android-ndk-r13b"

Java SDK: jdk-9.0.1

Thanks in advance

Kind reguards,

Unity is currently incompatible with JDK 9.0.1. Downgrade to JDK 8.

I solved the problem by changing the path of the JDK from C:/Users/user/Files/Unity/2019.3.15f1/Editor/Data/PlaybackEngines/AndroidPlayer\OpenJDK to C:/Users/userFiles/Unity/2019.3.15f1/Editor/Data/PlaybackEngines/AndroidPlayer/OpenJDK (See the last slash mark)

Actually, this seems to have been fixed since Unity 2018.3, because OpenJDK ships together with Unity by default. See the UPDATE remark in the above forum post.

Additionally, in my Unity 2020.1.8 installation, the JDK path is C:\Program Files\Unity\Hub\Editor\2020.1.8f1\Editor\Data\PlaybackEngines\AndroidPlayer\OpenJDK

i.e. no forward slash-backslash error per @riku_hei answer above.

But if you're on a 2019 version, you should be using the latest one 2019.4.15f1 (LTS).

I was on 2019.4.12f1 and after many and many and many building the error comes out of nowhere, so I've updated to 2019.4.15f1, but the error was still there. Riku_Hei's fix solve my problem.
