What I know: Android can load PNG, BMP, WEBP,... via BitmapFactory.

What I want to achive: Load my own 2D file format (e.g. 1-bit texture with a 1-bit alpha channel) and output a RGBA8888 texture.

Question: Is there any interface to achieve this?(or any other way)

The resulting image is used as a texture for a 3D model.

Why would you do that? Saving phone memory and download bandwidth while expanding the texture at runtime to RAM seems reasonable for very simple textures.
