- Support to build cpp application or library with bazel platform
- Support to build golang application or library with bazel platform
- Support to build android jni library with bazel platform(generate jni header automatically, end-to-end)
- Support to build android application(non-platform)
- WSL,Ubuntu18.04
- Bazel 3.3+
- Android JNI Library
- Local JDK 8+(just for using
javahorjavacto generate native headers)sudo apt install openjdk-8-jdk-headless
- Android sdkmanager (https://developer.android.com/studio#command-tools)
- config the environment of
sdkmanager sdkmanager --sdk_root=$HOME/Android --listsdkmanager --sdk_root=$HOME/Android 'build-tools;29.0.2'sdkmanager --sdk_root=$HOME/Android 'platforms;android-28'sdkmanager --sdk_root=$HOME/Android --install "ndk;18.1.5063045"- more older releases: https://developer.android.com/ndk/downloads/older_releases ,also you can get the support list by

To build this example you can use:
$ bazel build //cpp:hello-worldThis compilation will only use the default compiler of the local machine.
- step1: config your toolchains path:
toolchain/cpp/supported.bzl - step2: build
# Default compilation configuration, --cpu : ubuntu_gcc $ bazel build --config=compiler_config //cpp:hello-world # Specify the toolchain to compile the target $ bazel build --config=compiler_config --cpu=ubuntu_arm_linux_gnueabihf //cpp:hello-world- cpp
- golang
