What’s in the Android 5.0 SDK? Lollipop Android Big Power Full Update

he Android 5.0 SDK includes updated tools and new developer system images for testing. You can develop against the latest Android platform using API level 21 and take advantage of the updated support library to implement Material Design as well as the leanback user interface for TV apps.
You can download these components through the Android SDK Manager and develop your app in Android Studio:

• Android 5.0 SDK Platform & Tools
• Android 5.0 Emulator System Image - 32-bit & 64-bit (x86)
• Android 5.0 Emulator System Image for Android TV (32-bit)
• Android v7 appcompat Support Library for Material Design theme backwards capability
• Android v17 leanback library for Android TV app support

For developers using the Android NDK for native C/C++ Android apps we have:

• NDK r10c with API level 21 support

For developers on Android TV devices we have:

• Android 5.0 system image over the air (OTA) update for ADT-1 Developer Kit. OTA updates will appear over the next few days.

Similar to our previous release of the preview, we are also providing updated system image downloads for Nexus 5 & Nexus 7 (2013) devices to help with your testing as well. These images support the Android 5.0 SDK, but only have the minimal apps pre-installed in order to enable developer testing:

• Nexus 5 (GSM/LTE) “hammerhead” Device System Image
• Nexus 7 (2013) - (Wifi) “razor” Device System Image

For the developer preview versions, there will not be an over the air (OTA) update. You will need to wipe and reflash your developer device to use the latest developer preview versions. If you want to receive the official consumer OTA update in November and any other official updates, you will have to have a factory image on your Nexus device.
