Android export errors

Hello,

when I am trying to export my game for android, I am getting the two following errors after selecting the android sdk location:

1.) Error building Player: Win32Exception: ApplicationName='java.exe', CommandLine='-Dcom.android.sdkmanager.toolsdir="D:/Programme/Android SDK/android-sdk\tools" -classpath "D:/Programme/Android SDK/android-sdk\tools\lib\sdkmanager.jar" com.android.sdkmanager.Main list targets', CurrentDirectory='' UnityEditor.HostView:OnGUI()

2.) Exception: Error building Player: Win32Exception: ApplicationName='java.exe', CommandLine='-Dcom.android.sdkmanager.toolsdir="D:/Programme/Android SDK/android-sdk\tools" -classpath "D:/Programme/Android SDK/android-sdk\tools\lib\sdkmanager.jar" com.android.sdkmanager.Main list targets', CurrentDirectory='' UnityEditor.BuildPlayerWindow.BuildPlayerWithDefaultSettings (Boolean askForBuildLocation, BuildOptions forceOptions) (at C:/BuildAgent/work/842f9557127e852/Editor/Mono/BuildPlayerWindow.cs:367) UnityEditor.BuildPlayerWindow.GUIBuildButtons (Boolean enableBuildButton, Boolean enableBuildAndRunButton, Boolean canInstallInBuildFolder) (at C:/BuildAgent/work/842f9557127e852/Editor/Mono/BuildPlayerWindow.cs:972) UnityEditor.BuildPlayerWindow.ShowBuildTargetSettings () (at C:/BuildAgent/work/842f9557127e852/Editor/Mono/BuildPlayerWindow.cs:953) UnityEditor.BuildPlayerWindow.OnGUI () (at C:/BuildAgent/work/842f9557127e852/Editor/Mono/BuildPlayerWindow.cs:726) System.Reflection.MonoMethod.Invoke (System.Object obj, BindingFlags invokeAttr, System.Reflection.Binder binder, System.Object[] parameters, System.Globalization.CultureInfo culture) Rethrow as TargetInvocationException: Exception has been thrown by the target of an invocation.
