We’re creating a minimalist, light-themed “Double Exposure Blender” app for Android that helps artists merge two photos into a single, artistic image. Users should be able to pick a base photo, add an overlay, switch between common blend modes, adjust opacity, and refine the overlay with an eraser mask. Keep the canvas uncluttered: use an XML layout with a FrameLayout to stack the base image, overlay, and mask. Navigation is simple: a Bottom Navigation with New Project, My Gallery, and an Inspiration feed. When users cycle through blend modes, the transition should feel polished with a smooth cross‑fade. Finished images export as high‑quality JPEGs into the app’s external storage folder. Localize all UI text and blend mode names for hi‑IN and zh‑CN. Build the app in Kotlin and set up dev and release flavors, with the dev flavor exporting lower‑resolution outputs to speed testing.
