Emulator 27.2.3 Canary
Freitag, 30. März 2018
Emulator 27.2.3 is now available in the Canary channel. It contains the following changes:
Added a shortcut to go to the Screen Recording UI: Control + Shift + R (Command + Shift + R on Mac).
Changed the
-phone-number-prefix
command line option to
-phone-number
<number>
, allowing setting of the full phone number.
Screenshots can now be taken from the telnet console with either of these commands:
screenrecord screenshot
<destination-directory>
adb emu screenrecord screenshot
<destination-directory>
Screenshots are in PNG format.
Fixed a crash on start.
The frameless emulator's resize rectangle has been updated to better follow the emulator's visual theme.
Performance and antivirus software
We have been conducting tests to determine how to improve loading and saving times for AVD snapshots. In performing these tests, we have found that antivirus software packages that monitor every read and write operation can decrease performance for loads and saves. If your antivirus software provides the ability to whitelist applications, try whitelisting the Android Emulator application and see if performance improves. Also, if you have additional antivirus software installed beyond that which is included with your operating system, run some tests yourself to determine which gives you better performance with applications like Android Emulator.
Android Studio 3.2 Canary 8 now available
Montag, 26. März 2018
Android Studio 3.2 Canary 8 is now available in the Canary and Dev channels.
Inspect JNI References in the Memory Profiler:
If you deploy your app to a device running Android 8.0 (API level 26) or higher, you can inspect memory allocations for your app’s JNI code using the
Memory Profiler
. While your app is running, select a portion of the timeline that you want to inspect and select JNI heap from the drop-down above the class list, as shown below. You can then inspect objects in the heap as you normally would and double-click objects in the Allocation Call Stack tab to see where the JNI references are allocated and released in your code.
General bug fixes:
This update includes fixes for the following public issues:
Issue#72614343:
Gradle build fails to recover from invalid cached library
If you already have an Android Studio build on the
Canary or Dev channel
, you can get the update by clicking Help > Check for Update (or Android Studio > Check for Updates on Mac). Otherwise, you can

Emulator 27.2.1 canary
Freitag, 16. März 2018
Emulator 27.2.1 is now available in the Canary channel for Windows, Mac, and Linux,
bringing the fixes and enhancements from 27.2.0 to Windows
.
Emulator hang fix
We addressed a major source of emulator hangs on Windows by fixing an issue in QEMU 2.9. If you are still experiencing emulator hangs, please file an issue to
Issuetracker
. We are actively investigating emulator hangs and are making this a priority.
Screen recording enhancement
Audio encoding for screen recording has been moved off of the QEMU main loop to a separate thread to increase reliability and performance.
Other changes:
Fixed a crash on saving recorded video from screen recording.
Fixed an issue in which the VirtualScene camera's controls could steal focus too frequently on Xfce, and the mouse pointer could flicker.
Telephone and SMS are now properly deactivated when airplane mode is on.
Mac: Emulator window now properly shows a drop shadow when frameless mode is disabled.
To address issues caused by not having enough free disk space for snapshots, the emulator now checks for sufficient free disk space on startup, and will not start unless at least 2 GB is free.
Android Studio 3.2 Canary 6 now available
Montag, 12. März 2018
Android Studio 3.2 Canary 6 is now available in the Canary and Dev channels.
New Code Shrinker
R8 is a new tool for code shrinking and obfuscation that replaces ProGuard. You can start using the preview version of R8 by including the following in your project’s
gradle.properties
file:
android.enableR8 = true
Changed default ABIs for multi-APKs
When
building multiple APKs
that each target a different ABI, Android plugin for Gradle 3.2.0-alpha5 and higher no longer generate APKs for the following ABIs by default:
mips
,
mips64
, and
armeabi
.
If you are using NDK r16b or lower and you want to continue to build APKs for those ABIs, you need to include them explicitly in your app’s
build.gradle
file, as follows:
splits {
abi {
include
'armeabi', 'mips', 'mips64'
...
}
}
NDK r17 users
: If you are using
NDK r17 beta 1
or higher, you can no longer build APKs for
mips
,
mips64
, or
armeabi
using Android plugin for Gradle 3.2.0-alpha5 or higher.

Issue#67035929
