API Level in Android refers to a numeric identifier that represents a specific version of the Android operating system and its available features. It helps developers determine which Android versions their applications can support and what system functionalities are accessible.
In Android app development, API Levels are important for maintaining compatibility across different devices and Android versions. Developers use them to define minimum supported versions and ensure apps work correctly on newer or older devices.
For example:
- An Android app may require API Level 24 or higher to use advanced notification features.
- Developers test applications on multiple API Levels to ensure compatibility across devices.
- Some modern Android features are only available in higher API Levels.
- An app with a lower minimum API Level can run on older smartphones.
Common technologies and concepts related to API Levels include:
- Android SDK
- Android Studio
- SDK Versioning
- Backward Compatibility
- Min SDK Version
- Target SDK Version
- Android Operating System
- Mobile App Testing
- App Compatibility
