native-libandroidthings's Introduction

Android Things Native Library

This repository contains the symbols and the headers for the Android Things Native PIO API for the following architecture:

armeabi-v7a
x86

Note: The Android Things Console will be turned down for non-commercial use on January 5, 2022. For more details, see the FAQ page.

Usage

Unzip the latest release in the native project directory (or in a shared location if you have many native projects).
Add the following lines to the native project CMakeLists.txt:

set(CMAKE_MODULE_PATH ${CMAKE_MODULE_PATH} <path_to_FindAndroidThings_directory.cmake>)
find_package(AndroidThings REQUIRED)
include_directories(${ANDROIDTHINGS_INCLUDE_DIRS})
target_link_libraries(<your_target_name> ${ANDROIDTHINGS_LIBRARIES})

Add the following arch to the native module build.gradle:

defaultConfig {
    ndk {
        abiFilters 'armeabi-v7a', 'x86'
    }
}

native-libandroidthings's Issues

Security Policy violation Binary Artifacts

This issue was automatically created by Allstar.

Security Policy Violation
Project is out of compliance with Binary Artifacts policy: binaries present in source code

Rule Description
Binary Artifacts are an increased security risk in your repository. Binary artifacts cannot be reviewed, allowing the introduction of possibly obsolete or maliciously subverted executables. For more information see the Security Scorecards Documentation for Binary Artifacts.

Remediation Steps
To remediate, remove the generated executable artifacts from the repository.

Artifacts Found

armeabi-v7a/lib/libandroidthings.so
x86/lib/libandroidthings.so

Additional Information
This policy is drawn from Security Scorecards, which is a tool that scores a project's adherence to security best practices. You may wish to run a Scorecards scan directly on this repository for more details.

Allstar has been installed on all Google managed GitHub orgs. Policies are gradually being rolled out and enforced by the GOSST and OSPO teams. Learn more at http://go/allstar

This issue will auto resolve when the policy is in compliance.

Issue created by Allstar. See https://github.com/ossf/allstar/ for more information. For questions specific to the repository, please contact the owner or maintainer.

When are you supporting Software PWM in android things?

It would really handy if you could bring in software PWM in Android things.
Any plan for that?

Thanks

android things - kotlin and NATIVE NDK with UPM/MRAA/I2C intel driver-died

Hi, I have this driver:

https://github.com/intel-iot-devkit/upm/blob/master/src/smartdrive/smartdrive.hpp

https://github.com/intel-iot-devkit/upm/blob/master/src/smartdrive/smartdrive.cxx

androidthings/contrib-drivers#70

My intention is to transpose this driver to use it on rapsberry pi 3/SmartDrive and command my 2 car windshield motors using android things

I know the first thing is remove upm/mraa libs from the .hpp and .cxx files above, and my questions is:

1 - What is the best way to do this? (already preparing for the creation of a * .h file that will be used below:)

libandroidthings/
${ABI}/
include/
pio/
*.h
lib/
libandroidthings.so

Kotlin/Native usage examples

Hi,
Kotlin can already be used on the non NDK side, but it could also be used on the NDK side with Kotlin/Native now in EAP! Could you provide at least one example using Kotlin/Native in an Android Things project along with Kotlin outside of the NDK when possible? Thanks!
