How do I build a native (command line) executable to run on Android?

by

As of NDK r8d, this can be solved in a much simpler way.

  1. Create a project with the following directory hierarchy:

    project/
    jni/
        Android.mk
        Application.mk
        *.c, *.cpp, *.h, etc.

  2. Fill in Android.mk with the following content. The most important thing is the last line. Check the NDK doc for the meaning of the other variables.

    LOCAL_PATH := $(call my-dir)

include $(CLEAR_VARS)

LOCAL_MODULE := name-of-your-executable
LOCAL_SRC_FILES := a.cpp b.cpp c.cpp etc.cpp
LOCAL_CPPFLAGS := -std=gnu++0x -Wall -fPIE         # whatever g++ flags you like
LOCAL_LDLIBS := -L$(SYSROOT)/usr/lib -llog -fPIE -pie   # whatever ld flags you like

include $(BUILD_EXECUTABLE)    # <-- Use this to build an executable.

  3. Go to the project/ directory, and simply type

    ndk-build

    The result will be placed in project/libs/<arch>/name-of-your-executable.
