Removed spurious print on refresh of snapshot RAM file.

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
