rayturbo

Android studio native project template using cross platform raylib graphics library.

This project use Android Studio with gradle and cmake to easily build apk files for arm, arm64, x86, x86_64.

The raylib library is built in c, however this project is adapted to the c ++ language to be able to quickly prototype applications. (c / c++ mix) for that name contain turbo.

/app/src/main/cpp/libs folder contain prebuilt version of debug static raylib for all mobile platforms. But beware because the library is built with different options for the compiler:

raylib makefile:

this line: ifeq ($(ANDROID_ARCH),arm64)

          ORG: CFLAGS += -target aarch64 -mfix-cortex-a53-835769
          
          NEW: CFLAGS += -m64

To build apk you need Android Studio software and ndk configured and installed.
I tested this under linux debian frankenstein version:) environment.

Requirements:

Linux pc machine
Railib library prebuild for android , is included inside project libs folder.
Android Studio: https://developer.android.com/studio/index.html
Android NDK & SDK: (available for download in Android Studio)

You need some system configuration for additional paths and enviroment variables:

Well, add lines to yours file .bashrc or .profile one of this hidden files inside home directory
replace build tools version, mine: 31.0.0
replace ndk version to fit, mine: 23.0.7599858
replace java path and version, mine: /home/$USER/JDK/graalvm-ce-java16
replace android sdk path to match you needs mine: /home/$USER/Android/Sdk

This below config is important for building raylib from sources and it comes in handy for the terminal operations.

export JAVA_HOME="/home/$USER/JDK/graalvm-ce-java16"
export ANDROID_SDK_ROOT=/home/$USER/Android/Sdk
export ANDROID_HOME=$ANDROID_SDK_ROOT
export ANDROID_NDK_HOME=/home/$USER/Android/Sdk/ndk/23.0.7599858

export PATH="$PATH:$ANDROID_SDK_ROOT/build-tools/31.0.0:
$ANDROID_SDK_ROOT/cmdline-tools/latest/bin:
$ANDROID_SDK_ROOT/emulator:
$ANDROID_SDK_ROOT/tools:
$ANDROID_SDK_ROOT/platform-tools:
$JAVA_HOME/bin:
$ANDROID_NDK_HOME:
$ANDROID_HOME/bin"

here is one line export path version:
export PATH="$PATH:$ANDROID_SDK_ROOT/build-tools/31.0.0:$ANDROID_SDK_ROOT/cmdline-tools/latest/bin:$ANDROID_SDK_ROOT/emulator:$ANDROID_SDK_ROOT/tools:$ANDROID_SDK_ROOT/platform-tools:$JAVA_HOME/bin:$ANDROID_NDK_HOME:$ANDROID_HOME/bin"

Important! 💣 🧨
Tips for Android studio: consider change java version from 1.8 under project structure settings to java >= 11 , for build this project i use java 16 from: https://www.graalvm.org/
You can successfully use java provided by android studio or from debian repositories.
