Let’s delve into the specific enhancements that distinguished Android 7.0 Nougat from its predecessor, Android 6.0 Marshmallow, exploring the practical implications for everyday users.
Key Differences and Innovations
User Interface and Experience
While both Marshmallow and Nougat shared a similar Material Design aesthetic, Nougat introduced subtle yet impactful visual refinements. The quick settings panel, for instance, received a significant overhaul. In Marshmallow, accessing additional quick settings required a second swipe down, often leading to a slightly cumbersome experience.
Nougat streamlined this by allowing users to expand the quick settings panel with a single swipe down, revealing more toggles directly. Furthermore, the ability to add or remove quick settings tiles directly from the expanded panel made customization more intuitive and accessible. This meant less time navigating through menus and more time controlling essential functions with greater ease.
The notification shade also saw a substantial redesign in Nougat. Marshmallow’s notifications were largely individual cards, which could quickly clutter the screen with numerous apps sending alerts. Nougat introduced notification bundling, grouping similar notifications from the same app together. This organization drastically improved the clarity and manageability of the notification area, making it easier to see what was important at a glance.
Beyond bundling, Nougat enabled direct reply functionality within the notification itself. Users could respond to messages or emails without needing to open the corresponding app, a significant time-saver for quick communications. This interactive notification system was a major step forward in leveraging the notification shade as a more functional hub.
Another notable UI improvement in Nougat was the introduction of a new “Recent Apps” screen. Marshmallow’s recent apps screen was a simple vertical scroll of app thumbnails. Nougat changed this to a card-based carousel that was more visually appealing and included a “Clear All” button at the top, a convenient way to close all background applications.
The settings menu also underwent minor tweaks, with a more prominent search bar at the top and suggested settings based on user behavior. This proactive suggestion system aimed to guide users towards features they might find useful, enhancing discoverability. These seemingly small changes collectively contributed to a smoother, more efficient, and visually pleasing user experience in Nougat.
Multitasking Capabilities
Perhaps the most significant and talked-about feature introduced in Android 7.0 Nougat was native split-screen multitasking. This allowed users to run two applications side-by-side on their screen, a feature previously available only on some manufacturer-skinned versions of Android or through third-party apps.
The implementation was straightforward: long-press the overview button (the square icon that shows recent apps), and then tap on the desired app. The screen would split, allowing you to select a second app from your recent apps list to run alongside the first. A draggable divider allowed users to adjust the screen real estate allocated to each app, offering a truly customizable multitasking experience.
This feature was a game-changer for productivity on larger screens, such as tablets and larger smartphones. For example, a user could be watching a YouTube video in one window while simultaneously browsing a recipe in another, or referencing a document while composing an email. This dramatically improved the utility of mobile devices for tasks that previously required a laptop or desktop computer.
Nougat also introduced picture-in-picture (PiP) mode, primarily for Android TV but also available on some phones. This allowed certain video apps to continue playing in a small, floating window even when the user navigated to a different app. While not as widely adopted on phones initially as split-screen, it demonstrated Google’s commitment to enhancing multitasking across different form factors and use cases. Marshmallow, in contrast, offered no native support for these advanced multitasking functionalities.
The ability to switch between recent apps with a double-tap of the overview button was another subtle but powerful multitasking enhancement in Nougat. This allowed for rapid switching between the two most recently used applications, similar to the Alt+Tab functionality on desktop operating systems. It significantly sped up workflows where users frequently toggled between two specific apps, such as messaging and a web browser.
These multitasking advancements in Nougat were a clear indication of Google’s focus on making Android devices more capable and versatile, blurring the lines between mobile and traditional computing. Marshmallow, while stable and functional, lacked this inherent ability to seamlessly manage multiple applications concurrently.
Performance and Battery Life
Android 6.0 Marshmallow was a significant step forward for battery optimization with the introduction of Doze mode and App Standby. Doze mode intelligently restricted background app activity when the device was stationary and not in use for a prolonged period, significantly conserving battery power. App Standby worked similarly but on a per-app basis, limiting network access and CPU usage for apps that hadn’t been used recently.
These features were lauded for their effectiveness in extending battery life without requiring user intervention. They worked passively in the background, ensuring that users could go longer between charges. Marshmallow’s focus on efficiency was a welcome improvement over previous Android versions, which were often criticized for their battery drain.
Android 7.0 Nougat built upon this foundation of efficiency, introducing further optimizations that made the system more fluid and responsive. While it didn’t introduce a revolutionary new battery-saving feature on the same scale as Doze, it refined existing processes and improved the overall resource management of the operating system. This resulted in a smoother user experience, with less lag and faster app loading times.
Nougat also brought Project Svelte to completion, a long-term initiative aimed at making Android run more efficiently on a wider range of devices, including those with less RAM. This meant that even lower-end devices could offer a more stable and performant experience. The operating system became more adept at managing background processes and memory, leading to a snappier feel in daily use.
Furthermore, Nougat introduced Vulkan API support, a low-overhead, cross-platform 3D graphics API. This was particularly beneficial for gaming and graphics-intensive applications, allowing for improved performance and reduced CPU usage compared to OpenGL ES. While not directly impacting battery life in all scenarios, it contributed to a more efficient use of the device’s processing power for demanding tasks. The overall system performance in Nougat felt more polished and less resource-intensive, a testament to Google’s continuous efforts in optimizing the Android platform.
Security and Privacy
Android 6.0 Marshmallow marked a pivotal moment for user privacy with the introduction of granular app permissions. Prior to Marshmallow, apps requested all their necessary permissions upon installation, often presenting users with a long, daunting list they were forced to accept or reject entirely.
Marshmallow changed this by implementing a runtime permission model. Permissions were now requested contextually, only when an app needed to access a specific feature or data. Users could then grant or deny these permissions individually, and even revoke them later through the app’s settings. This gave users unprecedented control over their data and device resources, fostering a more secure and transparent environment.
For instance, a photo editing app would only ask for camera permission when the user attempted to take a photo within the app, rather than requesting it at installation. This made the permission system much more understandable and manageable. This was a massive leap forward for user privacy.
Android 7.0 Nougat continued to build on Marshmallow’s security and privacy enhancements. It introduced improved security for direct boot, allowing devices to encrypt themselves and start up securely without user intervention. This meant that even before a user unlocked their device, essential system components and apps could start securely, enhancing the overall security posture.
Nougat also featured more robust security for media playback, with improved DRM (Digital Rights Management) capabilities. This was particularly important for streaming services and protected content, ensuring that media could be played securely and without unauthorized access. Additionally, the operating system incorporated stronger security measures against malware and malicious apps, further safeguarding the user’s device and data.
The platform also saw improvements in how it handled sensitive data, with more secure background operations and enhanced data isolation between apps. While the fundamental shift in permission management occurred in Marshmallow, Nougat refined and solidified these security measures, making the Android ecosystem a safer place for users and their personal information. The focus on privacy and security was a clear priority for Google.
Developer Features and APIs
Beyond the user-facing features, both Marshmallow and Nougat introduced significant advancements for developers, enabling them to create richer and more powerful applications. Marshmallow brought with it Android M Developer Preview, which laid the groundwork for many of the features we’ve discussed, including runtime permissions and Doze mode. It also introduced Direct Share, allowing apps to present specific contacts or content destinations directly in the share menu.
Android 7.0 Nougat continued this trend with a host of new APIs and developer tools. One of the most impactful for developers was the introduction of Multi-window support, which developers could leverage to ensure their apps functioned correctly and looked good in split-screen mode. This required developers to adapt their layouts and user interfaces to accommodate different screen sizes and orientations.
Nougat also introduced improved support for JIT (Just-In-Time) compilation, which significantly sped up app installation and app updates. The JIT compiler analyzes app code during runtime and compiles it into native machine code, leading to faster execution and reduced memory usage. This meant that apps launched faster and ran more smoothly.
Another key developer-focused feature was the introduction of Notification Channels. This allowed users to categorize and control notifications from apps on a much finer level than before. Developers could define different channels for various types of alerts (e.g., “important messages,” “promotions,” “updates”), and users could then enable or disable specific channels within the app’s settings. This provided a more granular control for users and a better way for developers to manage their app’s communication.
The platform also saw enhancements in background execution limits, encouraging developers to adopt more efficient practices for background tasks. This aligned with Project Svelte’s goals of improving overall system performance and battery life. Developers were encouraged to use newer APIs like WorkManager for deferrable background tasks, ensuring that the system could manage them more efficiently.
Nougat also brought support for Unicode 9.0, including new emojis, and improvements to the WebView component for better web rendering. These developer-focused updates ensured that the Android ecosystem continued to evolve, providing a more robust and feature-rich platform for app creation and innovation. The ongoing development of APIs and tools was crucial for the platform’s growth.
Under the Hood: System-Level Changes
While users primarily interact with visible features, both Marshmallow and Nougat brought substantial under-the-hood improvements that contributed to their overall stability and performance. Marshmallow’s introduction of the ART (Android Runtime) runtime as the default was a significant shift, replacing Dalvik. ART offered better performance, improved battery efficiency, and ahead-of-time (AOT) compilation, meaning apps were compiled during installation rather than at runtime.
This transition to ART in Marshmallow was a foundational step that made subsequent Android versions run more smoothly. It meant that apps generally started faster and consumed fewer resources. The move away from Dalvik was a critical modernization of the Android platform.
Nougat continued this optimization trend with further refinements to ART. It introduced a new compiler that improved the efficiency of app execution and reduced memory overhead. This meant that even with the added features of Nougat, the system remained remarkably efficient.
File-based encryption was another significant security enhancement introduced in Nougat. Unlike full-disk encryption, file-based encryption allows different parts of the device’s storage to be encrypted independently. This means that core system services and apps can start up and run before the user unlocks the device, enabling features like “Direct Boot” and ensuring that even essential functions are protected. Marshmallow’s encryption was more of a traditional full-disk approach.
Nougat also featured a more efficient system for handling background services. It imposed stricter limits on what apps could do in the background, preventing rogue applications from consuming excessive resources and draining the battery. This system-level control was crucial for maintaining a fluid and responsive user experience across a wide range of devices. The continuous refinement of the operating system’s core components was a hallmark of these releases.
The way the system managed memory and processed tasks was further optimized in Nougat. This resulted in a more stable operating system with fewer crashes and a generally more reliable performance over extended periods. These deep-level changes, while not always apparent to the average user, were fundamental to the improved experience offered by Nougat.
Practical Examples and Use Cases
Multitasking in Action
Imagine you’re on a trip and need to book a hotel while also coordinating with your travel companion via messaging. With Android 7.0 Nougat’s split-screen mode, you could have your hotel booking app open on one half of the screen and your messaging app on the other. You could simultaneously browse available rooms and prices while typing out messages to confirm details with your friend, all without constantly switching between apps.
This is a scenario that would have been incredibly cumbersome on Marshmallow, requiring frequent switching and potentially losing your place in one of the apps. The ability to see and interact with both applications at once dramatically streamlines such tasks, making your phone a more powerful productivity tool on the go. This efficiency gain was a major selling point for Nougat.
Another example involves learning a new skill. You could be following an online tutorial video in one window, with the corresponding application or practice environment open in the other. This allows for hands-on learning and immediate application of what you’re seeing, a far more effective method than trying to memorize instructions from a separate app.
Enhanced Notifications
Consider a busy morning where you receive multiple emails, text messages, and app alerts. In Marshmallow, each notification would appear as a separate card, quickly filling up your notification shade. In Nougat, all your text messages from a single contact would be bundled together under one expandable notification.
You could then tap to expand the bundle and see individual messages, and even reply directly to a text message without leaving the notification shade. This organization prevents your notification list from becoming overwhelming and allows for quicker responses to important communications. It transforms the notification area from a simple log into an interactive hub.
This direct reply feature is particularly useful when you’re in an app where switching out would disrupt your workflow, like a game or a complex form. A quick reply from the notification saves time and maintains focus. The ability to manage and interact with notifications directly from the pull-down menu was a significant convenience.
Privacy Control
With Android 6.0 Marshmallow’s runtime permissions, you could install a flashlight app and it wouldn’t automatically get access to your contacts. Only when you tried to use a feature that required contact access (which is unusual for a flashlight app, but illustrates the point) would it prompt you for permission. You could then deny it, and the app would still function as a flashlight.
This granular control meant users were no longer forced to grant broad permissions to apps just to use their core functionality. It empowered users to make informed decisions about their data privacy, reducing the risk of apps accessing information they didn’t need. This was a critical step in building user trust.
Nougat continued this by further strengthening the security around how apps accessed sensitive data. While Marshmallow introduced the *what* of granular permissions, Nougat focused on refining the *how* and ensuring that the system itself was more secure in its handling of that data. The emphasis on privacy was a defining characteristic of this era of Android development.
Battery Management
If you leave your phone on a desk overnight and forget to charge it, Marshmallow’s Doze mode would kick in. It would significantly reduce background activity, meaning you’d wake up to a phone with a much smaller battery drain than you would have experienced on older Android versions. This meant your phone was ready to go when you needed it most.
Nougat, while not introducing a new battery-saving mode of the same magnitude, maintained and refined these power-saving efficiencies. The overall system optimization meant that battery consumption remained competitive, even with more advanced features running. The focus on efficiency ensured that battery life remained a priority.
This improved battery management meant users could rely on their devices for longer periods, reducing the anxiety of constantly searching for a power outlet. The passive nature of these optimizations made them incredibly user-friendly. A longer-lasting battery is always a welcome feature.
Conclusion
