Android 14

Introduction and historical context

Android 14 is the 14th major release of the mobile operating system developed by Google. This iteration is positioned as a significant update within the Android development timeline, maintaining the consecutive numbering that characterizes the system's stable versions.

The official announcement of this version took place on February 8, 2023, marking the beginning of its public development cycle. During the pre-release phase, the project was internally identified by the codename Upside Down Cake, a designation that followed the company's tradition of assigning dessert names to its Android versions.

The general availability of Android 14 for end users occurred on October 4, 2023. This date established the starting point for the widespread adoption of version 14 in the ecosystem of compatible devices, consolidating its scope as the operating system base for subsequent hardware and software launches on the platform.

Development and Release Cycle

The development process for Android 14 began with the first developer preview, which was initially available on devices from the Pixel 6 and Pixel 7 series. This phase allowed developers to test the operating system's new features before it was opened to the general public.

The public testing phase started on April 12, 2023, with the launch of the public beta. Throughout this period, Google distributed a total of 5 betas to refine the system's stability and performance. A significant milestone in this timeline was the stability date of the third beta, which was reached on June 7, 2023, marking a reference point for the software's maturity.

The final testing iteration, the fifth beta, was released on August 10, 2023. Following the completion of these validation phases, Android 14 reached general availability on October 4, 2023. At the time of its official launch, the initial devices to receive the operating system were models from the Google Pixel line.

Technical Requirements and Compatibility

Android 14 defines a set of minimum hardware and software specifications designed to ensure the performance and security of the operating system. Regarding processing architecture, the system requires a 64-bit processor, specifically based on the ARMv8 architecture or higher. This technical requirement aims to ensure compatibility with modern native libraries and the security optimizations implemented in recent versions of the system.

In terms of memory and storage, Android 14 requires a minimum of 3 GB of RAM for stable operation. Additionally, at least 32 GB of internal storage space is required, which allows for the installation of the operating system, pre-installed applications, and the user data necessary for a basic experience.

Software and Development Compatibility

For developers, Android 14 introduces API level 34. Integrating these new features requires the use of Android Studio Flamingo | 2022.2.1 or a later version. Regarding application compatibility, the system establishes that the minimum blocked SDK version is Marshmallow (6.0), while the minimum accepted targetSdk version is 23. These guidelines ensure that new or updated applications comply with the current security and performance standards of the Android ecosystem.

Security and Privacy

Android 14 incorporates a set of enhancements designed to strengthen the operating system's security layer and provide users with more granular control over their data. At the time of its release, the default security patch level was set to October 1, 2023, ensuring that compatible devices received the latest fixes for known vulnerabilities. The system maintains active security support, guaranteeing the continuous updating of critical components to mitigate emerging risks.

One of the highlighted novelties is Advanced Memory Protection, a feature aimed at preventing exploits that attempt to manipulate device memory. This measure adds an extra layer of defense against attacks seeking to compromise the stability and integrity of the operating system.

In the realm of credential and permission management, Android 14 introduces several tools to improve privacy:

• Credential Manager: Facilitates the secure management of login credentials.
• Safer Intents: Enhances security in communication between applications.
• Per-session permissions: Allows users to grant temporary permissions to applications, limiting data access only during the active session.
• Nearby Wi-Fi permission: Offers specific control over access to nearby Wi-Fi networks.
• Anti-phishing system: Incorporates mechanisms to detect and prevent identity impersonation attempts.
• Private space option: Enables the creation of an isolated space for sensitive applications and data.
• Reinforced sandbox: Increases application isolation to reduce the potential impact of vulnerabilities.

Additionally, notifications and quick settings have been redesigned to improve clarity and security in user interaction with the system. Regarding unlocking, an auto-unlock function has been implemented that activates after entering the correct PIN, optimizing the security experience without compromising device protection.

Accessibility Improvements

Android 14 introduces a series of specific enhancements designed to facilitate device interaction for users with various types of disabilities. Among the most notable additions is the implementation of nonlinear font scaling, a feature that allows for more granular and effective adjustment of text size. This system reaches a maximum font scale of 200%, providing greater readability without compromising the visual structure of the interface.

To streamline the modification of these settings, the system includes a font size quick setting. This option enables users to adjust the text scale directly from the quick settings panel, eliminating the need to navigate through multiple configuration menus.

In the realm of communication and sensory perception, Android 14 introduces flash notifications. This function utilizes the device's light to alert users to important events, a tool particularly useful for individuals with hearing impairments. Additionally, improvements to hearing aid compatibility and functionality have been made, optimizing the audio experience for those who use these assistive devices.

Finally, the system offers an improvement to the magnification feature, allowing for a more detailed and precise visualization of screen elements, which contributes to greater autonomy in the daily use of the device.

Support for foldable devices

Android 14 introduces specific improvements for managing devices with foldable screens, focusing on optimizing the user experience and adapting applications to new hardware geometries.

One of the key innovations is the foldable dual display API, which allows developers to implement a dual display mode. This feature facilitates interface management when the device is in its unfolded state, enabling smoother interaction and making the most of the available display area.

Additionally, a feature for changing the aspect ratio for specific apps has been incorporated. This capability, introduced in the first quarterly platform release (QPR1), allows adjusting the screen proportion to optimize content display in formats that require a particular aspect ratio, thereby improving compatibility and the quality of the multimedia experience on these devices.

Multimedia and codec support

Android 14 expands its multimedia format compatibility by incorporating support for new audio, video, and image codecs aimed at improving playback efficiency and quality.

In the video domain, the system includes support for the AV1 codec. For specific technical details regarding its implementation, refer to sections 5.2 and 5.3 of the corresponding technical documentation.

Regarding images, Android 14 supports the AVIF codec in its Image, Image collection, and Image sequence Baseline Profile. Additionally, support for Ultra HDR has been added, which operates with a bit depth of 10 bits.

As for audio, the system maintains compatibility with the AAC ADTS codec. For the Opus codec, the technical specifications detail the following capabilities:

• Decoding: Supports mono, stereo, 5.0, and 5.1 with sampling frequencies of 8000, 12000, 16000, 24000, and 48000 Hz.
