[Error] Missing or invalid ANDROID_SDK env variable

PsiloAzk · February 13, 2023, 1:05pm

Hello everyone!!

I’m trying Flax for the first time… is awesome!!
but I wanted to export an example to android, but it shows me this error.

I have sdk and set the environment variable.

I hope you can help me.

Saludos!

Welcome to the Flax forums!

It could be a few different things. The first thing I’d recommend is that you need to double-check the environment variable is set up correctly. (The name, path, etc.) Next, try restarting your computer.

If neither of those work, it’s likely an issue with the SDK. I use the Android 10.0 (API level 29) SDK and have no issues.

Thank you Spectrix!

Reinstall all android studio and only Android 10.0 (API level 29) and set environment variables again. and it worked!! I think so.
Now it shows me another error!
I don’t know what this error is about.

Could you share your log file? I think it should be located at \project-path\Cache\Cooker\Android.

Well, I can’t spot anything out of the ordinary. The only other thing I can recommend is to make sure there aren’t any compile errors with your scripts. That’s caused me weird build errors in the past. Maybe @mafiesto4 can help you more.

mafiesto4 · February 14, 2023, 1:50pm

Probably you need to run Android Studio and accept software licenses (some help: android - Automatically accept all SDK licences - Stack Overflow).

Example gardle log with similar issue:

I’ll update docs to reflect this info.

It looks like Android toolchain has been changed since we’ve added support for this platform thus the latest SDK/NDK version has some issues with setup. I updated Flax toolchain and docs to reflect this:

new docs:

github.com

FlaxEngine/FlaxDocs/blob/1.5/manual/platforms/android.md#android-setup

# Android

![Android](media/android.jpg)

## Technical information

Flax is compiled for Linux platform using **Android NDK** and build with **Android SDK**. Supported are system version Android 7 or newer (platform API level 24). Flax uses **Vulkan** for rendering graphics on Android (min. Vulkan 1.0).

## Android Setup

Follow these steps to setup your development PC for building game for Android platform. In case of problems, please follow official documentation of Android platform.

* Download and install **Android Studio** ([https://developer.android.com/studio](https://developer.android.com/studio))
  * Install **Android SDK** within Android Studio setup.
  * Set `ANDROID_HOME` env var to SDK location (typically `C:\Users\USERNAME\AppData\Local\Android\android-studio\sdk` on Windows)
* Install **NDK**
  * via Android SDK Manager: *Android SDK -> SDK Tools -> NDK (side by side)*
  * or manually via [https://developer.android.com/ndk/downloads/index.html](https://developer.android.com/ndk/downloads/index.html) and set `ANDROID_NDK` env var to install location) 
* Install **Java**
  * use in-built from Android Studio: set `JAVA_HOME` env var to `<android-studio>\jbr`

Thanks maiesto4!!
I haven’t slept trying to find a solution.

So, does it mean that the android option does’t work until a new 1.5 update?
or I can update the “Improve building” in my flax.
I’m a newbie… I’m learning about all this.

thanks!

mafiesto4 · February 14, 2023, 5:03pm

You can wait for 1.5 update which might come out this week (I hope so). I just tested and it correctly produces .apk which runs fine on Android phone.

PsiloAzk · February 14, 2023, 5:14pm

Awesome!!! I’ll be waiting it!!
I want to tell you that I am a visual artist and I have an art project in mind, so I am learning about game development. and I’ve been looking for a game engine for several months, testing them… and I recently found Flax Engine (the 9th one I’ve tried) and it seems amazing!!

PsiloAzk · February 21, 2023, 6:23pm

New error on 1.5.
help!

mafiesto4 · February 27, 2023, 12:54pm

Have you tried removing <project>\Output\Android folder to have clean build with Flax 1.5?
What Android SDK version do you have installed? That’s how it looks on my PC:

PsiloAzk · March 3, 2023, 4:13pm

Flax 1.5.6339 now it works!!!
thanks u!
