Moving Android Studio and Android Emulator to 64-bit versions




Posted by Sam Lin, Product Manager, Android





With Project Marble, the Android Studio team focused our efforts on making the fundamental features and flows of the Integrated Development Environment (IDE) rock-solid. Performance is an underlying tenant to delivering a high quality IDE. To this end, we are sharpening our product focus and we will only support 64-bit operating systems going forward. Using Android Studio with an 64-bit operating systems enables efficient access to memory for both the IDE and the Android Emulator, and overall leads to a better development experience. While this change will not affect most Android Studio users, this change does have an impact if you use 32-bit versions of Microsoft® Windows®. To aid in this transition for those developers using 32-bit versions of Microsoft Windows, we want to give you details on the upcoming depreciation timeline plus steps to take to be ready for this upcoming change.



Timeline




To minimize the impact of this change towards exclusively supporting 64-bit operating systems, we will first deprecate the 32-bit version. During the depreciation phase, both Android Studio and the Android Emulator will continue to work but the products will not receive new feature updates. During this transition period you can still download the product from the Android Studio web site. After one year, we will officially end product support and will remove the 32-bit product version download links. Note, if you have the 32-bit version of Android Studio previously installed during this period then the product should continue to work, but we will not provide a link for you to re-download the product. The exact dates for the depreciation and end-of-support period are in the table below:





















Supported 32-bit Product Version Deprecation from End of Support on
Android Studio IDE 3.6
December 31, 2019
 December 31, 2020
Android Emulator 28.0.25
Jun 30, 2019
 December 31, 2020



Advantages of a 64-bit development environment




There are a few advantages to using a 64-bit version of Android Studio, which include:




  • Performance - The IDE can perform better because it can access more than 4GB of memory. The increase in memory especially provides a better experience when you are working on a large project.

  • 64-bit App Support - You can build both 32-bit and 64-bit versions of apps if your app uses C/C++ native code. Testing on both architectures can help you to get ready for the 64-bit requirement on Google Play which starts on August 1st, 2019.

  • Testing on Emulators - Both the 32-bit and 64-bit Android Emulator system images are supported by the 64-bit version of the Android Emulator. This flexibility makes it easier to test your app in different Android environments with one development machine.


Next steps



To recap, before ending support for the 32-bit version of Android Studio, we want to inform you in advance, provide guidance, and allow for a one-year lead time to help you migrate to a 64-bit operating system. You can still use 32-bit versions of Android Studio, but be mindful that these version will not receive future updates. Therefore, if you want to migrate we suggest you start planning early so that you can continue to get the latest product updates and take advantage of the performance improvements of a 64-bit development environment.

Posted by Oli Gaymond, Product Manager Android Machine Learning On-Device Machine Learning enables cutting edge features to run locally without transmitting data to a server. Processing the data on-device enables lower latency, can improve privacy and allows features to work without connectivity. Achieving the best performance and power efficiency requires taking advantage of all available hardware. Android Neural Networks API 1.3 The Android Neural Networks API (NNAPI) is designed for running computationally intensive operations for machine learning on Android devices. It provides a single set of APIs to benefit from available hardware accelerators including GPUs, DSPs and NPUs. In Android 11, we released Neural Networks API 1.3 adding support for Quality of Service APIs, Memory Domains and expanded quantization support. This release builds on the comprehensive support for over 100 operations, floating point and quantized data types and hardware implementations from partners acro

Posted by Stephanie Cuthbertson, Director, Product Management Android 11 is here! Today we’re pushing the source to the Android Open Source Project (AOSP) and officially releasing the newest version of Android. We built Android 11 with a focus on three themes: a People -centric approach to communication, Controls to let users quickly get to and control all of their smart devices, and Privacy to give users more ways to control how data on devices is shared. Read more in our Keyword post . For developers, Android 11 has a ton of new capabilities. You’ll want to check out conversation notifications, device and media controls, one-time permissions, enhanced 5G support, IME transitions, and so much more. To help you work and develop faster, we also added new tools like compatibility toggles, ADB incremental installs, app exit reasons API, data access auditing API, Kotlin nullability annotations, and many others. We worked to make Android 11 a great release for you, and we can’t wait to se

Posted by Erica Hanson , Global Program Manager, Google Developer Student Clubs Google Developer Student Clubs , a program of university based community groups for students interested in Google developer technologies, recently started hosting study groups called Android Study Jams . The goal? Learn Android app development through hands-on codelabs in an online curriculum provided by Google. There are two tracks: one for students who are new to programming, and one for those who already have experience. Interested in participating? Facilitator materials are available for anyone to host Android Study Jams in their community - take a look and get to building. Google Developer Student Clubs are dedicated to helping students learn programming together, among peers, in a fun and interactive setting. While over 50 thousand students from all over the world have participated in these Android workshops, we wanted to highlight the exciting work from groups in Indonesia, Turkey, and Nigeria. F
