available for download on the stable channel.

This release is the culmination of the Project Marble effort

which means more stability, better performances,

and polished features in the ID and build system.

It also includes updates from [? ATNJ ?] 2019.1.

During the past few months, our engineers

fixed hundreds of bugs and memory leaks

resulting in fewer interface freezes,

especially when editing data binding expression

in XML, and two times faster link code analysis performance.

Android Studio has a maximum memory [? hip ?] size of 1.2

gigabyte by default. When you work

on a large project of this amount, it may not be enough.

With Android Studio 3.5, the ID will

recognize when your project needs more RAM

and notify you to increase the memory [? hip ?]

size in a notification, if your machine's configuration allows

it.

Thanks to user report, we realized

that recent antivirus programs on Windows

included Android Studio build and installation directories

as active scan targets.

Since these folders have many small files created and removed

over time, the I/O and CPU were partially

taxed which in turn impacts the overall [? building ?]

performance of Android Studio.

With the 3.5 release, Android Studio

will now check various directories

that could be impacted by the slowdown

and compare them against the list of excluded and virus

directories.

If it finds that any of these folders are not being excluded,

you will see a pop up notification

and link to help you guide through the optimal setup.

On the emulator side, we found out

that Google Play services were aggressively

running in the background because of the default power

settings.

We switched the default to Battery mode,

and background CPU usage declined by more than three

times which avoids having the cooling fans triggered even

when the emulator's idle.

We polished numerous features that are

critical to Android developers.

Gradle Sync was sometimes failing due to a cache issue,

when dependencies were periodically

deleted to save disk space.

The Layout Editor experience is now smoother,

especially when you work on [? constraints ?] between

elements with [? ConstraintLayout. ?] We also

made it easier to upgrade to project imported from

the previous version of Android Studio with guided fixes

to help you with the process.

Finally, for projects including C++,

CMake builds can now be up to 25% faster.

The Deployment toolbar also got a nice UI tweak

with a new target device dropdown.

It helps you switch easily between them whenever

you run your application.

And if you care about build speed, and you probably do,

the Android Gradle plug-in 3.5 brings incremental annotation

processing for data binding.

You need to set [? under ?] a Data Binding Incremental

to True in your Gradle properties.

Check the Gradle documentation website

to find other compatible annotation processors.

Incremental annotation processor compilation

wasn't available for Kotlin until now.

With the newest Kotlin plug-in version,

you can add this line to your Gradle property file

to enable it.

We had your feedback on Instant Run,

and we re-implemented with a more practical approach

from the ground up.

We call this new tool Apply Changes.

Its use-- platform-specific APIs from Android Oreo and higher

to ensure reliable and consistent behavior.

Unlike in [? Central, ?] Apply Changes

does not modify your APK.

You can read more about it on our blog post linked

in the description below.

Now, application sizes are always

something that's on our mind.

That's why we added [? super ?] 4 conditional delivery

for our bundles.

It allows you to set certain device configuration

requirements for dynamic feature modules

to be downloaded automatically during app install.

You can set conditional delivery based

on hardware features, such as OpenGL Versions, support

for augmented reality, API level, or even user country.

If you're running on a Chrome OS device

starting from version 75, you'll be

happy to hear that we have now a dedicated dev file installer

for Android Studio 3.5.

What's more, it now supports deployment and debugging

on USB-connected device.

We want to thank all the developers who helped us

by sharing metrics and user's data

anonymously on Android Studio.

You can help us as well, opting in the System Settings, Data

Sharing section.

Enjoy Android Studio 3.5, and remember

that we are listening to your feedback on our bug tracker.

See you soon.
