    I try to build APK with Unity 2019.1.7f1. I've installed Unity with Android SDK (througth the install process). Anyway I have the latest Android SDK manually and set up. But I get this message (as in the attached files).

    What can I do?

    Linux Mint 19.1, Unity 2019.1.7f1 (Android SDK included through the installation menu).

    Looks I have all that Unity needs to see.

    I've updated SDK path with my own SDK installation and it worked. But now I have another problem:

    stdout:
    il2cpp.exe didn't catch exception: System.Exception: Android NDK r13b or newer not detected at '/home/denis/Unity/Hub/Editor/2019.1.7f1/Editor/Data/PlaybackEngines/AndroidPlayer/NDK'.
    at Unity.IL2CPP.Building.ToolChains.Android.AndroidNDKUtilities..ctor (NiceIO.NPath ndkRootPath, Unity.IL2CPP.Common.Architecture architecture, System.Boolean useDependenciesToolChain) [0x00088] in <011fe0a303834fe7be028e204fa0c5a4>:0

    But I've changed NDK path to my own but it seems that Unity looking for NDK in your folder again.
    But Unity folder also exists:

     » ls -la /home/denis/Unity/Hub/Editor/2019.1.7f1/Editor/Data/PlaybackEngines/AndroidPlayer/NDK/android-ndk-r16b

    ...


    Looks like NDK field cannot be changed. But I've successfully changed it in the Unity's preferences. But it doesn't work.
    Also I tried with my own installation of ndk r20.

    Also I tried to use my own installation of r13b.

    In the console I have this error message:
    Failed running /home/denis/Unity/Hub/Editor/2019.1.7f1/Editor/Data/il2cpp/build/il2cpp.exe --convert-to-cpp --emit-null-checks --enable-array-bounds-check --dotnetprofile="unityaot" --compile-cpp --libil2cpp-static --platform="Android" --architecture="ARMv7" --configuration="Release" --outputpath="/home/denis/MyUnityProject/StagingArea/assets/bin/Data/Native/armeabi-v7a/libil2cpp.so" --cachedirectory="/home/denis/MyUnityProject/Assets/../Library/il2cpp_android_armeabi-v7a/il2cpp_cache" --additional-include-directories="/home/denis/Unity/Hub/Editor/2019.1.7f1/Editor/Data/PlaybackEngines/AndroidPlayer/Tools/bdwgc/include" --additional-include-directories="/home/denis/Unity/Hub/Editor/2019.1.7f1/Editor/Data/PlaybackEngines/AndroidPlayer/Tools/libil2cpp/include" --tool-chain-path="/home/denis/Unity/Hub/Editor/2019.1.7f1/Editor/Data/PlaybackEngines/AndroidPlayer/NDK" --profiler-report --map-file-parser="/home/denis/Unity/Hub/Editor/2019.1.7f1/Editor/Data/Tools/MapFileParser/MapFileParser" --directory="/home/denis/MyUnityProject/Temp/StagingArea/assets/bin/Data/Managed" --generatedcppdir="/home/denis/MyUnityProject/Temp/StagingArea/Il2Cpp/il2cppOutput"


    But in the NDK path I've set: /home/denis/Android/NDK/android-ndk-r13b
    And Unity every failed build resets my NDK path to its internal: /home/denis/Unity/Hub/Editor/2019.1.7f1/Editor/Data/PlaybackEngines/AndroidPlayer/NDK - that doesn't work for some reason. But the folder extists and there are no problems with the permissions.

    Need Help :)

    Solved: I've downloaded android-ndk-r16b and removed NDK from Unity's path. So I just replaced Unity's NDK with my downloaded ndk-r16b and pressed "Browse" button. Browse button very important thing becase it doesn't work if you just paste the right path without pressing on it :)

    Hi @HZ51

    SDK

    I had to do similar fix. For me the issue was Unity didn't download all directories.
    The dirs you listed installed by Unity:
    Code (CSharp):
    1. drwxrwxr-x  5 denis denis 4096 июн 20 07:10 .
    2.  
    3. drwxrwxr-x 10 denis denis 4096 июн 20 07:10 ..
    4.  
    5. drwxrwxr-x  3 denis denis 4096 июн 20 07:10 build-tools
    6.  
    7. drwxrwxr-x  3 denis denis 4096 июн 20 07:10 platforms
    8.  
    9. drwxrwxr-x  5 denis denis 4096 июн 20 07:10 platform-tools
    miss "tools" directory.
    I had similar fix to yours, either point to my own SDK directory or copy my SDK to Unity.
    Chose pointing to my own directory.

    NDK
    How did you manage to select your own NDK?
    I did download both 13 and 16, Unity needs 16 officially by default for 2019.1.
    All should be fine but Unity still doesn't detect the NDK.
    I get " exception: System.Exception: Android NDK r13b or newer not detected at"

    Another option is then to choose my own NDK directory, like before Unity 2019.
    Unfortunately Unity doesn't respect it. I can put my own path in preferences but if I run "build" command Unity defaults to default path.
    The same happen if I put my own NDK path and click browse, it resets value to default Unity path.
    Basically I can't select my own NDK path so building Android with IL2CPP doesn't' work for me, have to use mono.

    Couldn't find if similar issue is reported, maybe will create one.

    Unity 2019.1.11f
    Mint 18.2

    honestly, what's the whole point of giving the option to install the SDK/NDK with Unity if Unity itself does not recognize its own installed files?

    I am afraid some of the issues are related to Linux.
    I know they were hub upgrades since then, 2.1.0, and Unity 2019.2.1 upgrade has some potentially related fixes.
    Didn't test them yet since I moved to Windows for now, can't waste so much time on technical issues, but will do when get some time.

    If you have the opportunity to test it and you had the issue originally, would be great if you checked it.

    Actually Android SDK packaged together with Unity somehow doesn't include "tools" folder. One can download SDK from google website and copy "tools" folder into Unity/Hub/Editor/<Unity version>/Editor/Data/PlaybackEngines/AndroidPlayer/SDK/ folder.

    Got the same problem with Unity Hub 2.1.0 and Unity 2019.2.2f1 (on Ubuntu 19.04).

    Is there a reason the Tools folder is not included ?

    I've got the exact same problem with Unity Hub 2.1.0 and Unity 2019.2.2f1 (on Ubuntu 18.04).

    Also clicking on the browse button after the field where you can enter your own path to an android SDK doesn't let you browse to a location but enters the path of Unity's Android SDK into the field instead.
