In a nutshell,

First, to cross-compile your C code from your host machine, use NDK toolchain with sysroot option and position independent option -fPIE -pie.

$NDKROOT/toolchains/aarch64-linux-android-4.9/prebuilt/darwin-x86_64/bin/aarch64-linux-android-gcc \
--sysroot=$NDKROOT/platforms/android-22/arch-arm64 -fPIE -pie main.c -o main

the arch part arrch64 or arch-arm64, the toolchain version part 4.9, platform version part android-22, and the binary format for your host machine darwin-x86_64 may vary by your environment.

Second, push your binary under /data/local/tmp and execute it from adb shell.
