Android Emulator 28.0.6 changes:

Snapshots

Fixed sudden exit to desktop when deleting the currently loaded snapshot.
Removed spurious print on refresh of snapshot RAM file.

Initialization

Fixed crash on startup when parsing QEMU drive options if "file" parameter was not specified.

QEMU

Fixed leak of AIO context on Windows.

Note on emulator slowness: We've heard from some users that the emulator is slower than before, even after we fixed the hw.ramSize setting. If you are still experiencing problems with slowness on recent API levels (27, 28) versus earlier (23-26) we would appreciate your feedback. Please provide detailed information on your host OS, GPU, and CPU.

Note on non-ASCII characters: We would like to look into better handling of non-ASCII characters on Windows. If the emulator has trouble handling non-ASCII characters, especially when the language setting is not English, we would also appreciate your feedback. Please provide detailed information on your Windows locale and language settings, and what kind of strings were causing issues.

Emulator 27.3.10 Stable

2018年8月27日星期一

RAM size configuration fix

Recently, users have reported that the emulator is slower than before. We have tracked this down to the AVD RAM size in the AVD's config.ini being set incorrectly. To mitigate this, the emulator increases the minimum RAM level for API 26+ images to the Android Studio default, 1536 MB. Please file a bug if your AVD's config.ini is not listing hw.ramSize in megabytes. The file can be found in the data directory of the AVD:

~/.android/avd/<avdname>.avd/config.ini

27.3.9 bug-fix update

Recently, users have reported that the emulator is slower than before. We have tracked this down to the AVD RAM size in the AVD's config.ini being set incorrectly. To mitigate this, the emulator increases the minimum RAM level for API 26+ images to the Android Studio default, 1536 MB.

28.0.5 Canary
Snapshots

Starting the emulator from the command line with a snapshot (using the -snapshot command line option) will disable saving Quickboot on exit. This is to reduce unintentional overwriting of the Quickboot snapshot and to avoid using a slow fallback path that does not use file-backed Quickboot.
Fixed an issue where when upgrading from an older emulator version and running file-backed Quickboot for the first time, the Quickboot snapshot would get invalidated repeatedly.
We have received crash reports in which there was a crash on snapshot save or load. We have added more logging to OpenGL snapshots to debug the issue. If you are experiencing crashes, please file an issue.

Multiple AVD instances
We fixed an issue that caused launching multiple AVD instances with -read-only to fail on Windows.
