This leads to enhanced security, protecting against potential malware or unauthorized file modifications that could compromise your app's functionality or data.

6. Partial screen sharing

This innovative feature allows apps to share only a portion of their screen, enhancing privacy and multitasking capabilities.

The growing popularity of large-screen devices like foldable phones and tablets necessitates a tailored approach to user interfaces and app experiences. Android 15 acknowledges this shift with improved support for large screens, ensuring that apps adapt seamlessly and deliver an intuitive and visually appealing experience across diverse screen sizes.

Android 15 empowers developers with a plethora of new tools to streamline their workflows and unlock creative possibilities. Here are some of the most notable additions:

In-app camera controls:

This feature grants apps granular control over device cameras, enabling them to fine-tune camera settings and behaviors to cater to specific use cases.

Virtual MIDI 2.0 Devices

Developers can now create virtual MIDI devices within their apps, opening doors for innovative music creation and performance applications.

File integrity APIs

These APIs bolster app security by enabling apps to verify the integrity of files, ensuring they haven't been tampered with.

Additional Features and Potential Implications

Beyond the aforementioned highlights, Android 15 introduces a multitude of other features, each with the potential to significantly impact the development landscape. Some noteworthy additions include:

Improved app compatibility

Android 15 streamlines the app compatibility process, making it easier for developers to ensure their apps work seamlessly across diverse devices and Android versions.
