Practical Guide to Texture Mapping in OpenGL ES on Android: Passing Bitmap to Native Layer and Rendering

This tutorial explains how to transfer a Bitmap from Java to the native layer using the NDK, retrieve its pixel data with jnigraphics, create and configure an OpenGL texture, set up vertex and fragment shaders with proper texture coordinates, handle Y‑axis flipping on Android, and finally blend multiple textures for advanced rendering effects.
