The vibrant developer ecosystem and open platform have been important keys to Google’s success, which is why I’m excited to tell you that Google once again giving developers a very early preview of some of what’s in store.

As Stated earlier it is Just a Developers Preview and not the full and final release so Android DP1 is initially targeting Pixel, Pixel XL, Pixel 2, Pixel 2 XL, as well as Android Emulator,  So be conscious before installing Android P DP1 on any device, please check its targeting devices and make sure your device is one among those listed.

In the upcoming version of Android, Android P your early feedback is crucial to Google’s efforts to push the boundaries of mobile development.

1. JobScheduler Network Updates.

In Android P jobScheduler has been improved to let it better handle network related jobs.

Jobs can now declare their estimated data size, signal prefetching and specify detailed network requirements. For example when a network was reported by the carrier is being congested job scheduler might defer large Network requests, while it can take advantage of surplus metered capacity to run a prefetch job that returns content that will substantially improve the apps, user experience, such as prefetching top headlines.

2. Improving Apps Performance

Android P brings performance and efficiency improvements to art Androids runtime.  Google Team expanded arts use of execution profiles to optimize apps and reduce the in-memory footprint of a compiled app code.

Art now uses profile information for on device rewriting of Dex files with reductions of up to 11%, across a range of popular apps these correlate closely with reductions in system Dex memory usage and faster startup times.

3. Kotlin Compiler

Kotlin is seeing massive growth in the developer community. we have heard so much, Kotlin love from developers and google Team deepening their Kotlin investments. In P.  You’ll see the first results of Google platform work, with new optimizations, In art out – written with Kotlin will run faster on P than on previous versions of Android.

Also make sure to check out Google’s ongoing preview of android KTX which is a set of extensions designed to make android Kotlin development even more concise and pleasant.

4. Introducing ImageDecoder

Android introduces an easier way to decode images to either bitmaps or drawables with image decoder, which replaces bitmap factory.

Image Decoder

Image decoder election create a bitmap or drawable from a byte buffer, file or URI. It offers several advantages over bitmap factory including support for exact scaling, single step decoding to hardware memory, support for post-processing to code and decoding of animated images.

5. Animation

Android P introduces a new AnimatedImageDrawable class for drawing and displaying GIF and WebP animated images. AnimatedImageDrawable works similarly to AnimatedVectorDrawable in that RenderThread drives the animations of AnimatedImageDrawable. RenderThread also uses a worker thread to decode, so that decoding does not interfere with RenderThread. This implementation allows your app to have an animated image without managing its updates or interfering with your app’s UI thread.


Image decoder allows you to supply a callback that is called after the header is decoded where you can alter the output rather than having decode to head. Their twice decode drawable allows you to create drawables directly. The encoded image is an animated gif or web Page. The drawable will be an instance of the new animated image drawable

6. HDR VP9 Video

To help deliver the highest quality viewing experience, Android P adds built-in support for HDR VP9 profile – enabling the delivery of HDR enabled movies. Team Google Android P also added support for a substantially improved image compression with HAV C compressed a gif images, which means smaller downloads and less on device storage.

Every Android developer should start planning to migrate to target, at least API 26 now. And Team Google built the checklist of resources to help and support this efforts.


Google Android Team always looking for ways to improve the user and developer experience.  In this spirit we’re working to ensure that apps don’t use non SDK interfaces since doing so risks crashes for users and emergency rollouts for developers in Android and they restricted the set of symbols at NDK code could use and with Android P or further increasing stability by expanding these restrictions to cover the SDK interfaces as well in the preview.


you’ll see a warning when you use a non SDK interface that team google plan to restrict. If you feel that you’ll need the SDK API expanded to stop using non SDK ones, please let us know as soon as you can via our bug tracker.

14. Introducing FingerprintDialog,

Android P providing a standard system dialog to prompt the user to touch the fingerprint sensor, managing text and placement as appropriate for the device. Apps can trigger the system fingerprint dialog using a new fingerprint dialog API.
