MAVLink UDP Android Example

This is a fork of MAVLink UDP Example created by Bryan Godbolt, rewritten for Android using JNI. The app sends some data to QGroundControl using the MAVLink protocol.

• Open local.properties and edit sdk.dir and ndk.dir properties (paths to your Android SDK and NDK):

  ndk.dir=~/Library/Android/android-sdk-linux/ndk-bundle
  sdk.dir=~/Library/Android/android-sdk-linux

• Download: c_library_v2 or generate: generate_libraries MAVLink headers.

• Open /mavlink-udp/src/main/cpp/Android.mk and edit LOCAL_CFLAGS variable so that it points to the folder where you keep the headers.

LOCAL_PATH := $(call my-dir)

include $(CLEAR_VARS)
LOCAL_CFLAGS += -I ~/mavlink/generated/include
LOCAL_MODULE    := mavlink_udp
LOCAL_SRC_FILES := mavlink_udp.c
include $(BUILD_SHARED_LIBRARY)

• If you're having trouble building the project (The system cannot find the file specified) - try downloading older NDK version.

system_id and component_id values are both set to 1 by default, but can be set by the user.

Latest build of the app can be downloaded here: mavlink-udp-debug.apk.

To establish connection check your Android device's IP address and add target host in QGroundControl:

Start UDP server in the app and it will start sending heartbeat, attitude, location and battery status:
