Hello,

What is the difference between these 3 dependency archives for Android?

https://github.com/supertuxkart/depende ... /master?q=

android/dependencies-android-1.1.1.tar.xz
android/dependencies-android-ndk20.tar.xz
android/dependencies-android.tar.xz

Which should I extract to stk-code/lib/ ?

android/dependencies-android-1.1.1.tar.xz if you are compiling latest master

Thank you! I could compile STK under Ubuntu and it runs there.

Now sorry about my dumb question: But how do I compile for Android? Is there a cross-compilation toolchain or something? I do not understand the note about the dependencies for Android when it is compiled under Linux (e.g. Ubuntu). Where/how is the Android package (apk) built? Since I am fairly new to software development, please bear with me and my humble questions. :blush:

Oh my bad - I should of course have read the rest as well. :blush: Sorry that I wasted your time!
I will now dig into this and see how much progress I can to on Android.

PS - sorry, one more question about this:

You need also Android SDK for android-19 platform (the API for Android 4.4) and
Android NDK. Version r20 is recommended, because it's known that it works
without issues.

When I go to this page, I only see one version for Linux:

{l Code}: {l Select All Code}

Linux (64-bit)    android-studio-ide-192.6392135-linux.tar.gz (772 MB)


Is this the correct one?

AFAIK, once Android Studio is installed, you can download the version of the SDK you need from Tools->SDK Manager.

The command line tools only are not sufficient, or are they?

Command line tools only
If you do not need Android Studio, you can download the basic Android command line tools below. You can use the included sdkmanager to download other SDK packages.

I just wonder why should I download that stuff, when I could also do this?

{l Code}: {l Select All Code}

sudo apt install android-sdk


PS:
Is it still true as of today that Android NDK version r20 is recommended, because it's known that it works without issues? Meanwhile, there is NDK r21b.

Yes, those command-line tools should do the job AFAIK (you had just posted a link to full Android Studio, so I based my answer around it.)

You can build with r21 if u compile the git with 1.1.1 pack

Thank you both! I am still setting everything up. For those other interested users, you might find the following links useful about installing Android SDK and NDK on Linux/Ubuntu. Well, the following worked for me:

{l Code}: {l Select All Code}

sudo apt update && sudo apt install android-sdk

But then I ran into some problem (Android command line tool sdkmanager always shows: Warning: Could not create settings), which I could resolve with hints there:
https://stackoverflow.com/questions/604 ... -create-se
Search for this comment:

The sdkmanager tries to figure out the android-sdk path based in where it's unpacked, without use the environment variables, like ANDROID_SDK_ROOT. But it's get worse, because it have a hard coded parent folder named cmdline-tools and if you unzip commandlinetools inside a folder with another name, it doesn't work, forcing us to use the parameter sdk_root to feed the inside variable correctly.

So, with that in mind we can use the following approach to solve this.
...

And then I got:

{l Code}: {l Select All Code}

sdkmanager "Warning: Failed to read or create install properties file"

WHich I could resolve with this:

{l Code}: {l Select All Code}

sudo chmod -R a+w [path/to/android/sdk]

Hint sources:
https://askubuntu.com/questions/1227439 ... line-tools
https://github.com/bitrise-steplib/step ... /issues/57

Finally, I installed the NDK (well, I hope that is correct):

{l Code}: {l Select All Code}

sdkmanager --no_https ndk-bundle

More is there:

I will look further into this in the following days and hope that it is ok that I post these details and links here (maybe helpful for others as well).

Before running the compilation, run the generate_assets script, so that
selected assets will be copied to "assets" directory, and then included in the
apk file.

Can you please provide me with some more guidance how to do this? I.e. where is the generate_assets script located?
Thanks a lot!

it's all in android folder

Thank you. So I set the environment paths and symlinks for SDK and NDK and can execute make:

user@ubuntu:~/stk-code/android$ ./make.sh -j5
./make.sh: 226: [: =: argument expected
Creating standalone toolchain
HOST_OS=linux
HOST_EXE=
HOST_ARCH=x86_64
HOST_TAG=linux-x86_64
HOST_NUM_CPUS=4
BUILD_NUM_CPUS=8

What does "226: [: =: argument expected" right after the call mean?

The host (Synology DS918+ with QuadCore CPU and 8 GB RAM) is shown as "HOST_NUM_CPUS=4" as expected; however, why is "BUILD_NUM_CPUS=8" when I invoke the make process with "-j5" (5 threads)? If this is not really relevant or/and off-topic here, please ignore this question.

PS for the record: The build process (with all 26 actionable tasks executed) took about 5 minutes.

Success! I got "android-debug.apk", could install it on my Samsung Galaxy S7 EDIT: and also on my Fire TV stick - and it runs.
So it seems that I have a working development/testing environment.

Thanks once more for your kind patience and helpful hints!

forum {l Wrote}:What does "226: [: =: argument expected" right after the call mean?

It appears immediately after make (but the compilation runs through nevertheless):

{l Code}: {l Select All Code}

user@ubuntu:~/stk-code/android$ ./make.sh -j5
./make.sh: 226: [: =: argument expected
Compiling STK


If 226 is the code line number in make.sh (I am not sure about this, as I am not an expert of coding and such), then here is the code block in question (I added the line numbers 221 to 231):

{l Code}: {l Select All Code}

221    # Find newest build-tools version
222    if [ -z "$BUILD_TOOLS_VER" ]; then
223        BUILD_TOOLS_DIRS=`ls -1 "$SDK_PATH/build-tools" | sort -V -r`
224       
225        for DIR in $BUILD_TOOLS_DIRS; do
226            if [ "$DIR" = `echo $DIR | sed 's/[^0-9,.]//g'` ]; then
227                BUILD_TOOLS_VER="$DIR"
228                break
229            fi
230        done
231    fi


So is there maybe a problem in line 226 of make.sh?

{l Code}: {l Select All Code}

if [ "$DIR" = `echo $DIR | sed 's/[^0-9,.]//g'` ]; then

I do not know what [: =: argument expected means, sorry.

The build process ends like this:

{l Code}: {l Select All Code}

Building APK
Starting a Gradle Daemon (subsequent builds will be faster)

> Configure project :
Observed package id 'build-tools;debian' in inconsistent location '/usr/lib/android-sdk/build-tools/27.0.1' (Expected '/usr/lib/android-sdk/build-tools/debian')

BUILD SUCCESSFUL in 1m 24s
26 actionable tasks: 7 executed, 19 up-to-date


Should I be concerned about the message regarding the inconsistent location? Is a softlink (ln -s) needed here?

The apk is there:

{l Code}: {l Select All Code}

-rw-rw-r-- 1 user user       234 Jun 18 18:49 output.json


What is the json file for?

Can you show content of the build-tools directory? The 226 line probably should have quotes around command. And I think that you don't need to care about that json file.

Thank you so much for your help!
Since I am unsure, which folder you mean, I show several:

There is probably "debian" directory and the script didn't expect it to be there. Do you have standard build-tools with numbers there too? Eg. 29.0.2 or something like this.

There is a softlink regarding the standard Debian build tool - see above.
However, now I wonder why I have both: 27.0.1 (softlinked) and 28.0.3?

PS (if that matters at all):
Also the different user:group (root:root vs. user:user) makes me wonder.
I installed SDK and NDK as root and created the softlinks as root (if I remember correctly), whereas I pulled git, updated the assets, and started the build process as user.


And I should mention:

The built android-debug.apk runs perfectly on a Samsung S5 mini phone.
Is there anything I should specifically test and report back here (or on GitHub?) on the latest Android git version?

Because different projects need different build-tools versions, so you can install more of them. STK uses newest available version by default.

You shouldn't see this warning in current git anymore.

Thank you!
