This project demonstrates how to access and write into a "window" framebuffer in Android.

As it stands, it just lit every line of pixel of the window with a color randomly selected in a palette of 4 colors.

The useful part of the example is inside fill_pixels.c.
android_native_app_glue.c is, as the name implies, just a way to connect Android's NativeActivity code to this native code.

If you want to test this code, you'll need :

• An Android SDK with the right build tools (27.0.0);
• An Android NDK (used by the Android build system to get the right compilers for each architecture);
• An Android terminal (Phone, tablet, emulator, ...).

Then you will need to execute, from a terminal workig in this folder :

git submodule init
git submodule update
cd apk
./gradlew installDebug
