Emulator 27.2.3 Canary

Friday, March 30, 2018

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.

Emulator 27.2.1 canary

Friday, March 16, 2018

bringing the fixes and enhancements from 27.2.0 to WindowsEmulator 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.

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.
