OpenGL ES Demo

About

This is a basic OpenGL ES 3.2 demo using C++ and SDL3 for Android.

Building

Prerequisites

• Unix-like system
• Bash
• Meson
• Ninja
• OpenJDK
• Android SDK
• Android NDK

Cross file setup

Create 2 Meson cross file for 32 bit and 64 bit ARM Android device:

[host_machine]
system = 'android'
cpu_family = '<aarch64|arm>'
cpu = '<armv8-a|armv7-a>'
endian = 'little'

[constants]
api_level = '35'
ndk = '<ndk root path>/'
ndk_bin = ndk + 'toolchains/llvm/prebuilt/linux-x86_64/bin/'

[binaries]
ar = ndk_bin + 'llvm-ar'
as = ndk_bin + 'llvm-as'
c = ndk_bin + ' <aarch64|arm>-linux-<android|androideabi>' + api_level + '-clang'
cpp = ndk_bin + '<aarch64|arm>-linux-<android|androideabi>' + api_level + '-clang++'
ld = ndk_bin + 'ld'
ranlib = ndk_bin + 'llvm-ranlib'
strip = ndk_bin + 'llvm-strip'
pkg-config = 'false'

Building the APK

meson setup --cross-file <path to cross file> -Dbuildtype=debug .build/obj
meson compile -C .build/obj

Signing the APK
