YACINE REZGUI: Android Studio version 3.5 is now
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
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
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
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.
Check out early builds of Android Studio 3.6
on the [? camera ?] channel.
See you soon.
