This week, Google announced a Developer Preview of the N release of Android
Some details via the Android Dev Blog…
Here are a few APIs and features we want to highlight which are available as a part of the Android N Developer Preview today, with more to come as we continue developing the release:
Multi-window – A new manifest attribute called android:resizableActivity is available for apps targeting N and beyond. If this attribute is set to true, your activity can be launched in split-screen modes on phones and tablets. You can also specify your activity’s minimum allowable dimensions, preventing users from making the activity window smaller than that size. Lifecycle changes for multi-window are similar to switching from landscape to portrait mode: your activity can handle the configuration change itself, or it can allow the system to stop the activity and recreate it with the new dimensions. In addition, activities can also go into picture-in-picture mode on devices like TVs, and is a great feature for apps that play video; be sure to setandroid:supportsPictureInPicture to true to take advantage of this.
Note: The N Developer Preview includes an updated SDK with system images for testing on the official Android emulator and on Nexus 6, Nexus 5X, Nexus 6P, Nexus Player, Nexus 9, and Pixel C devices (and to help test out these features on a tablet, developers can get a $150 discount on Pixel C).
