First, make sure you have the NDK:

Here is the easiest way to compile a C binary for your phone:

http://developer.android.com/tools/sdk/ndk/index.html

http://www.kandroid.org/ndk/docs/STANDALONE-TOOLCHAIN.html

Usually $NDK(may be different) =

Linux:

/home//android-ndk

Mac OS X:

/Users//android-ndk

In Terminal:

# create tool-chain - one line
# New method in ndk 12.
$NDK/build/tools/make_standalone_toolchain.py --arch arm --install-dir=/tmp/my-android-toolchain
# Old method.
#$NDK/build/tools/make-standalone-toolchain.sh --platform=android-3 --install-dir=/tmp/my-android-toolchain

# add to terminal PATH variable
export PATH=/tmp/my-android-toolchain/bin:$PATH

# make alias CC be the new gcc binary
export CC=arm-linux-androideabi-gcc

# compile your C code(I tried hello world)
$CC -o foo.o -c foo.c

# push binary to phone
adb push foo.o /data/local/tmp

# execute binary
adb /data/local/tmp/foo.o
