Introduction to Android 7.0 Nougat

Overview:
Android 7.0 Nougat brought a bunch of new features and improvements to the Android operating system. It was a significant update that aimed to make devices faster, more efficient, and easier to use. Nougat introduced several changes that enhanced the overall user experience, making it a noteworthy release in the Android lineup.

Release Date:
Android 7.0 Nougat officially started rolling out on August 22, 2016. The initial rollout began with Nexus devices, which typically get updates first. Other manufacturers followed suit, gradually making Nougat available on their devices over the following months.

Key Takeaways:

Android 7.0 Nougat made multitasking easier with split-screen mode, letting you use two apps at once, and improved battery life with better background app management.
Nougat boosted security by making apps ask for permissions only when needed and encrypting data by default, keeping your information safer.

Key Features

Split-Screen Mode:
One of the standout features of Android 7.0 Nougat was the introduction of split-screen mode. This feature allowed users to run two apps side by side on their screen, making multitasking a breeze. Whether you wanted to browse the web while watching a video or chat with friends while checking your email, split-screen mode made it possible to do both without constantly switching between apps.

Inline Replies to Notifications:
Nougat also brought inline replies to notifications, a feature that made responding to messages quicker and more convenient. Instead of opening an app to reply, users could respond directly from the notification shade. This saved time and made it easier to stay engaged in conversations without interrupting other tasks.

Doze Mode Improvements:
Doze mode, which was introduced in Android Marshmallow, got even better in Nougat. The enhanced Doze mode kicked in more aggressively when the device was not in use, extending battery life by putting the device into a deeper sleep state. This meant your phone would conserve power more effectively, especially when it was idle for long periods.

System Behavior Changes

Battery and Memory

Android 7.0 Nougat introduced several tweaks to help your device last longer and run smoother. Battery life saw a boost thanks to more aggressive background app management. Apps that you aren't actively using get put to sleep faster, saving precious battery juice.

On the memory side, Nougat reduced how much RAM apps use. This means fewer slowdowns and crashes, especially on devices with less memory. By optimizing how apps run in the background, Nougat made multitasking more efficient.

Project Svelte

Project Svelte aimed to make Android run better on devices with limited resources. It did this by cutting down on unnecessary background processes. For instance, it limited how often apps could wake up your device, which helped save both battery and memory. This project made Android more accessible to a wider range of devices, including those with lower specs.

Security Enhancements

Permissions Changes

Nougat made app permissions more transparent and user-friendly. Instead of asking for all permissions upfront, apps now request them as needed. For example, a messaging app will ask for access to your contacts only when you try to add a new contact. This approach gives you more control over your data and helps protect your privacy.

TLS/SSL Default Configuration Changes

Security got a big boost with changes to TLS/SSL configurations. These protocols encrypt data sent over the internet, making it harder for hackers to intercept. Nougat made these security features the default for all apps, ensuring safer communication and data transfer.

Developer Features

JIT Compiler

The new Just-In-Time (JIT) compiler in Nougat made apps run faster and more efficiently. Unlike the old compiler, which translated code all at once, the JIT compiler does it on-the-fly. This means quicker app launches and smoother performance. Plus, it helps reduce the amount of storage space apps need.

NDK Apps Linking to Platform Libraries

For developers using the Native Development Kit (NDK), Nougat brought changes to how apps link to platform libraries. This update made it easier to build and maintain apps that rely on native code, improving compatibility and performance across different devices.

Accessibility Improvements

Screen Zoom

Android 7.0 Nougat introduced a screen zoom feature, making it easier for users to adjust the display size. This feature allows users to zoom in on their screens, making text and images larger. It's especially helpful for those with vision impairments, as it provides a more comfortable viewing experience. Users can find this option in the display settings, where they can choose the level of zoom that suits their needs best. Whether you need a slight adjustment or a significant enlargement, screen zoom offers flexibility to enhance readability and overall usability.

Vision Settings in Setup Wizard

During the initial setup of a device, Nougat includes vision settings in the Setup Wizard. This addition ensures that users with visual impairments can configure their devices right from the start. Options like magnification gestures, font size adjustments, and color correction are available, making the setup process more inclusive. By integrating these settings early on, Android ensures that all users can personalize their devices to meet their accessibility needs without navigating through multiple menus later.

Enterprise Features

Android for Work

Nougat brought several enhancements to Android for Work, catering to enterprise users. One of the key features is the ability to separate work and personal data on the same device. This separation ensures that sensitive work information remains secure while allowing personal use of the device. Additionally, IT administrators gained more control over device management, including app permissions and security policies. These improvements make Android a more viable option for businesses looking to provide employees with flexible, secure mobile solutions.

Other Notable Changes

File System Permission Changes

Android 7.0 Nougat made significant changes to file system permissions. These changes aimed to improve security by restricting how apps access files. Apps now need explicit permission to access certain directories, reducing the risk of unauthorized data access. This means that users have more control over which apps can read or modify their files, enhancing overall device security.

Sharing Files Between Apps

Nougat also improved the process of sharing files between apps. The new system uses a more secure method called FileProvider, which grants temporary access to files. This method ensures that apps can share files without compromising security. Users can now share photos, documents, and other files more seamlessly, knowing that their data remains protected. This improvement not only enhances user experience but also maintains the integrity of shared information.

Wrapping Things Up

Android 7.0 Nougat packed a punch with its split-screen mode, inline replies to notifications, and Doze mode improvements, making everyday tasks smoother and faster. These updates, along with better battery management, enhanced security features, and more developer tools, pushed the boundaries of what Android could offer. Even the small touches, like screen zoom and file sharing enhancements, showed that Nougat aimed to cater to everyone—from regular users to tech enthusiasts. If your device ran on Nougat, you likely enjoyed a more efficient, secure, and user-friendly experience.
