I’m looking to have a full-featured image editor built for Android. The app should let users: • make basic adjustments such as crop, rotate, and resize, • apply a variety of filters and effects in real time, and • carry out advanced editing with layers, masks, and spot-retouching tools. A clean, touch-friendly interface is essential, and performance must stay smooth even on mid-range devices. Please structure the code so I can compile it in Android Studio, and include clear README instructions along with all source files, assets, and third-party library references. If you’ve shipped similar imaging or graphics projects before, share a brief example and note any open-source components you plan to use (e.g., GPUImage, OpenCV). I’m happy to discuss UI mock-ups, icon sets, and any edge cases you foresee once you’ve reviewed the scope.
