Starting in Android N DP4, the system negotiates resource locales individually for each resource object before the app activates.As announced at Developer Preview 3, we’ve deferred the Launcher Shortcuts feature to a later release of Android. In Developer Preview 4, we’ve removed the Launcher Shortcuts APIs.We’ve changed the BLE Scanning behavior starting in DP4. We’ll prevent applications from starting and stopping scans more than 5 times in 30 seconds. For long running scans, we’ll convert them into opportunistic scans.The Multi-Window android:minimalHeight and android:minimalWidth attributes have been renamed to android:minHeight and android:minWidth.
