[bug] running `tauri android init` returns `NDK_HOME` environment variable isn't set, but the NDK is installed

[TickJar]

Describe the bug

After following the prerequisites doc to the letter, installing Android Studio and downloading all the latest SDKs and NDKs, I'm still getting this error when running tauri android init:

action request:  to initialize Android environment; Android support won't be usable until you
fix the issue below and re-run `tauri android init`!
    Have you installed the NDK? The `NDK_HOME` environment variable isn't set, and is
    required: environment variable not found

What can be causing this to KEEP happening? This results in Android Studio reporting Error running 'app' Default Activity not found after running tauri android dev

Reproduction

No response

Expected behavior

Tauri should be able to detect the installed NDK

My mistake, here is the tauri info output:

So i assume by "following the prereqs" included this android part right? https://tauri.app/start/prerequisites/#android If so, can you share the output of ls $ANDROID_HOME/ndk ?

So i assume by "following the prereqs" included this android part right? https://tauri.app/start/prerequisites/#android If so, can you share the output of ls $ANDROID_HOME/ndk ?

So I have run into this a few times. It seems like following the guide you mentioned above points NDK_HOME to a folder that doesn't exist... but it does...

export NDK_HOME="$ANDROID_HOME/ndk/$(ls -1 $ANDROID_HOME/ndk)"

So this is leading to some enlightenment on my end. I'm not sure if this is expected behavior, but entering these commands into my terminal doesn't seem to stick when I set these variables in the project folder via the terminal in my IDE (vsCode).

This did result in tauri android init running successfully. However, now tauri android dev results in a lengthy and cryptic error:

Also, after running tauri android dev, running tauri android init results in the same error appearing:

I'm not sure if this is expected behavior, but entering these commands into my terminal doesn't seem to stick when I set these variables in the project folder via the terminal in my IDE (vsCode).

It is, if you want them to be permanent you have to add that to .zshrc or .zprofile. idk why the docs are missing that

same issue

[burakakca]

When I use it directly in Terminal it works, but otherwise it does not.

[Rcmane]

I made it work by adding environment variables:

export ANDROID_HOME="$HOME/Android/Sdk" export ANDROID_NDK_HOME="$ANDROID_HOME/ndk/28.0.12916984" export NDK_HOME="$ANDROID_HOME/ndk/28.0.12916984"

It seems that the method given by tauri prerequisites: export NDK_HOME="$ANDROID_HOME/ndk/$(ls -1 $ANDROID_HOME/ndk)" not works, especially when you have more than one ndk verisons.

[akcrittenden]

I found a workaround! I named the environment variable "NDKROOT" instead of "NDK_HOME". Ran npm run tauri android init and npm run tauri android build and it built successfully. Was able to run my app on my phone via wireless debugging too! Can someone confirm?

[F-Kirchhoff]

@Rcmane method worked for me as well. I replaced the $(ls -1 $ANDROID_HOME/ndk) with the literal folder name, in my case 29.0.13113456. I think the error is that the $(ls -1 $ANDROID_HOME/ndk) resolves to /Users/ph1/Library/Android/sdk/ndk/\033[34m29.0.13113456\033[39;49m\033[0m, which includes the \033[34m and \033[39;49m\033[0m strings, which set the text color in the terminal.

This is due to my alias of ls to ls --color=auto.

I could fix the code by: A: setting the ndk folder name manually to 29.0.13113456 NDK_HOME="$ANDROID_HOME/ndk/"

B: making sure that ls does not use colors by adding --color=never: NDK_HOME="$ANDROID_HOME/ndk/$(ls --color=never -1 $ANDROID_HOME/ndk)"

[AravindPrabhs]

This was my issue - I think the docs should be updated with the --color=never flag.

In my case, the issue is caused by the fact that I have two versions of ndk, and after running the command in the docs, my 'NDK_HOME' environment variable becomes C:\Users\20030813\AppData\Local\Android\Sdk\ndk\26.1.10909125 29.0.13113456 It's not a correct path, just need to pick a version, I changed it
C:\Users\20030813\AppData\Local\Android\Sdk\ndk\29.0.13113456 Anything will be right

The problem is not really the color, it is the fact that ls -l will resolve to multiple lines if the user has more than one NDK installed. The guide should use ls $ANDROID_HOME/ndk | tail -n 1 instead.
