JXcore is ready for Android OS. On this tutorial, we will give you a step-by-step instruction on how to compile JXcore for Android targets.

First, you need Android NDK. You can download the latest NDK from here

Assuming you have already extracted Android NDK into ~/androidNDK folder, next step is to use our prebuilt script file to create Android toolchains before the compilation process.

Before starting, please check the prerequisites from this link

Go to root folder of jxcore project and;

$> build_scripts/android-configure.sh ~/androidNDK/

This should create android-toolchain and android-toolchain-intel folders under the project's root folder.

Compile as a Standalone Process

$> build_scripts/android_standalone.sh ~/androidNDK/ intel sm

Instead of 'intel' you can also set 'arm' for ARM target. sm symbolizes Spider Monkey, for V8 engine set v8

When the compilation process is completed, you can find the 'jx' binary is available under out_android folder.

Compile as a Static Library

Now we can compile jxcore for android. type;

$> build_scripts/android_compile.sh ~/androidNDK/

The sample above uses SpiderMonkey, if you want/need V8, better use android_compile_v8.sh instead.

Compilation will take some time. When it's finished, you can find the binaries and include files for ARM and INTEL platforms under out_android/android folder.

ARM64 or MIPSEL

By default build script (SM - static library) doesn't compile for ARM64 and MIPSEL targets. In order to enable one or both of them, open build_scripts/android_compile.sh file and edit the lines below accordingly;

By default;

MIPS=0 #out_mipsel_droid
ARM64=0 #out_arm64_droid

Replace to;

for MIPSEL

MIPS=out_mipsel_droid

for ARM64

ARM64=out_arm64_droid

Embedding LeveDB and Leveldown

User --embed-leveldown argument.

example

$> build_scripts/android_compile.sh ~/androidNDK/ --embed-leveldown
