Illustrative Examples

Diving deeper into the Android N Developer Preview on the Sony Z3, we’ll explore practical code examples demonstrating key features. This section will focus on showcasing how new APIs and functionalities integrate with the existing Sony Z3 platform. We’ll also examine the adjustments needed to run these examples smoothly, highlighting any performance or compatibility concerns.This section provides practical demonstrations of Android N features.

It contrasts code snippets from previous versions to highlight improvements and modifications necessary for the Sony Z3. The visual representation will help understand how the new features manifest on the Sony Z3’s emulator or a similar device.

New APIs for Background Tasks

The Android N preview introduces enhanced APIs for handling background tasks more efficiently. This improves battery life and user experience by allowing for more granular control over background processes. The following code snippets illustrate this:

// Android N (Sony Z3)
BackgroundTaskManager taskManager = BackgroundTaskManager.getInstance();
taskManager.scheduleTask(new MyBackgroundTask(), TaskPriority.LOW);

// Previous Android Version
new Thread(new MyBackgroundTask()).start();

The new `BackgroundTaskManager` API allows developers to prioritize background tasks more effectively. The `TaskPriority` enumeration allows you to set the importance of the task. This is crucial on the Sony Z3 to ensure smooth multitasking without compromising battery life. The `BackgroundTaskManager` API handles resource management and ensures background tasks don’t consume excessive system resources.

The Sony Z3 emulator or device will display the background task running in the background, with no noticeable impact on the main UI.

Improved Resource Management

Android N offers more granular control over resources. This enables applications to use resources more efficiently. The code examples show how to optimize memory usage:

// Android N (Sony Z3)
MemoryManager memoryManager = MemoryManager.getInstance();
memoryManager.requestMemory(1024);

// Previous Android Version
// No explicit memory management

The new `MemoryManager` API in Android N allows for explicit memory allocation, reducing memory leaks and improving application performance. This is especially important on the Sony Z3, a device with limited memory. The emulator or device running this code will demonstrate the impact of this change.

The application will perform more smoothly, especially during intensive operations, because it’s actively managing memory allocation. Visual indications of memory usage may be available on the emulator.

Handling Multi-Window Mode

Android N provides more robust support for multi-window mode. The following example demonstrates how to detect and respond to multi-window changes:

// Android N (Sony Z3)
if (WindowManager.isMultiWindowModeEnabled()) 
    // Adjust UI elements for multi-window mode


// Previous Android Version
// No multi-window mode support

The addition of `isMultiWindowModeEnabled()` makes it easier for developers to tailor their applications to the multi-window mode. This is essential for the Sony Z3, enabling applications to be used efficiently in different window configurations.

The emulator will showcase the application behaving differently when running in a multi-window environment. The UI elements will be adjusted accordingly.
