Bug Error Message: > NDK is not installed See the Console for Details <

I got often the Error

NDK is not installed See the Console for Details



when I chose

Build And Run

to create my Android App.



I use Unity Version 2022.2.12



With previous Unity Versions this Error comes not up.

The Error comes up from Line 71:

Code (JavaScript):

1. commandLineArgs.add("--tool-chain-path=" + android.ndkDirectory)

The Variable:

Code (JavaScript):

1. android.ndkDirectory

delivers not a Vallid result.


The Settings for the NDK Path are:






The strange thing is that for 5 attempts to create the app it works once without this error message.

I use newest Win 11 Pro Version.


Unfortunately, the error occurs after 10 minutes because it takes so long to compile.


The project is currently stopped because I can no longer create the Android app for testing.




The Error comes also with Version

2023.1.0b9

and

2023.2.0a7

up.


Some Time it helps to reboot the Win 11 Computer.

I have found out that the problem also occurs on win 10 !

 

After hours of testing I have solved Problem by adding the Line (in my case):

Code (JavaScript):

1. android {
2.     ndkPath "D:/Unity/Editor/2023.2.0a7/Editor/Data/PlaybackEngines/AndroidPlayer/NDK"
3. ...

to my

mainTemplate.gradle

File.

After this the compiling process success.

 

Thanks @Westbang. Your line fixed it for me, but I wanted to find a more generic path to the NDK, so I checked the mainTemplate.gradle file in the .../Editor/Data/PlaybackEngines/AndroidPlayer/Tools/GradleTemplates directory. It includes the below in the

android

block:

Code (JavaScript):

1. android {
2.     ndkPath "**NDKPATH**"
3. }
