I need a clean, lightweight Android utility focused purely on file management—specifically, moving files from one device to another. Think of it as a straightforward “send-receive” tool that a user can open, pick any file on local storage, and push it to another phone or tablet without fuss. Core requirements • It must excel at file transfer between devices. I’m open to the underlying transport method—Bluetooth, Wi-Fi Direct, nearby-share style over local network, or a combination—so long as transfers are reliable and fast. • The interface should follow current Material guidelines so the listing looks polished on Google Play. • No cloud backup, compression, or other extras are needed at this stage; keeping the scope tight is a priority. I’ll be publishing the finished APK myself through my Google Play Console, so what I need from you is: 1. Complete Android Studio project with well-commented Kotlin or Java code (Kotlin preferred). 2. Signed release APK/AAB ready for upload. 3. Simple text or markdown file containing build steps, key features, and any required permissions for the store listing. 4. App icon (adaptive) and a couple of sample screenshots so I can pass initial review without scrambling for graphics. Acceptance criteria • Transfers a 100 MB file between two Android 10+ devices in under two minutes on the same Wi-Fi network. • No crashes or ANR in a 20-minute stress test. • Passes Play Store pre-launch report with zero “critical” issues. If you’ve built a similar utility before, point me to a demo or repo so I can see it in action. Let’s keep the codebase tidy and lean so future features—like cloud sync or compression—slot in easily when we expand.
