Developer Preview 5 is Compatibility Test Suite (CTS) approved on these devices: Nexus 5X, Nexus 6, Nexus 6P, Nexus 9, and Pixel C. Apps that depend on CTS approved builds should work normally on these devices (Android Pay for example).

New in DP5
Updated system images for supported devices and emulator
Developer Preview 5 includes near-final system images for supported devices and the Android emulator. The images include the final APIs (API level 24) for the upcoming Android N platform. When you are done testing, you can publish apps using API level 24 to Google Play, in alpha, beta, and production release channels.

Known Issues
Stability
Users may encounter system instability (such as kernel panics and crashes).
Multi-window
MapView may be blank when resized in multi-window mode and not focused.
Camera
Apps may encounter Intermittent issues recording and playing back video at 240fps.
Do Not Disturb
Do Not Disturb mode may be set at device reboot. To work around the issue, delete the existing rule for VR as follows: go to Settings > Sound > Do not disturb > Automatic Rules and tap the trash icon next to the VR rule.
Screen zoom and multiple APKs in Google Play
On devices running Developer Preview 5, Google Play services 9.0.83 incorrectly reports the current screen density rather than the stable screen density. When screen zoom is enabled on these devices, this can cause Google Play to select a version of a multi-APK app that’s designed for smaller screens. This issue is fixed in the next version of Google Play services.
Vulkan support and multiple APKs in Google Play
On devices running Developer Preview 5, Google Play services 9.0.83 currently reports Vulkan support but not Vulkan version. This can cause Google Play to select a version of a multi-APK app that’s designed for lower Vulkan support on devices with higher version support. Currently, the Google Play Store does not accept uploads of Apps which use Vulkan version targeting. This support will be added to the Google Play Store in the future any Android N devices using the Google Play services 9.0.83 will continue to receive versions of Apps targeting basic Vulkan support.
Android Auto
The version of Google Maps included in Developer Preview 5 (9.30) crashes when used with Android Auto. This issue will be fixed in the next update to Google Maps (9.31), expected in the coming weeks.
Notes on publishing apps that target API 24
Before publishing apps that target API 24 in Google Play, keep these points in mind:

If your app’s current targetSdkVersion is 22 or lower and you want to target API 24, you’ll need to support behaviors introduced with Android 6.0 (Marshmallow), such as runtime permissions, in addition to Android N behaviors.
Once you publish an app with targetSdkVersion set to 23 or higher, you can't later publish a version of the app with a higher versionCode that targets 22 or lower. This restriction applies in alpha and beta channels as well as production channel.
