rysasahrialThe Smart Android Alarm Clock repository delivers a powerful, minimalist alarm application designed for Android devices. Built on clean Kotlin code with a minimal Java footprint, it prioritizes essential features—like gentle alarm, custom snooze, and volume fade‑in—over bloated extras. This clean alarm clock source code is ideal for developers seeking an Android alarm manager, a sleep‑aware alarm scheduler, or a user‑friendly time picker.
The app’s code originates from the Android Open Source Project (AOSP) and is licensed under Apache 2.0, providing full flexibility for modification, commercial distribution, and reuse. The main components include a Jelly Bean–style time picker, a pre‑alarm gentle wake, vibration after fade‑in, and long‑press dismiss behavior—features that deliver enhanced usability without the complexity of full clock suites.
By featuring a modern, phone‑style keyboard input, the user interface promotes faster time entry than traditional wheel pickers. The code integrates a pre‑alarm low‑volume trigger that gently rouses the user before the main tone—when they are most naturally in a light sleep cycle. A distinct volume fade‑in algorithm, followed by vibration only after fade completion, ensures alarms wake users gradually.
Developers working with Android AlarmManager and scheduling logic will appreciate how the repository handles alarm lifecycle events, including snooze to a set time, adjustable snooze duration, and security for accidental dismissals. A long‑press on the snooze button invokes a custom snooze time picker, while long‑press dismiss requires deliberate user input, reducing premature alarm shut‑off.
The AlarmClock GitHub project includes nearly 2,000 commits, 550+ stars, and solid coverage via Travis CI and Codecov. Contributors and issue reporters are welcome—submit bug reports, feature requests, or pull requests. The Kotlin‑centric codebase (91% Kotlin, 8% Java) targets Android 4.1+, supporting a broad device ecosystem. All critical modules—AlarmDatabaseHelper, AlarmReceiver, UI components, and Gradle build scripts—are well-organized for easy extension.
Whether you’re integrating an alarm scheduler library, building a wake‑up tone selector, or studying Android alarm source code, this repository delivers a clean, ready-to‑use foundation. The intuitive UI paired with robust scheduling makes it an optimal base for developers aiming to create personalized alarm apps with powerful yet sleek functionality. Plus, the Apache 2.0 license ensures you can adapt, distribute, and commercialize without licensing hassles—as long as you include proper attribution and don’t sue the author.
