概要
Androidの開発環境をアップデートする時用のメモです。
(アップデート時の障害回避用に検索したので、実際の現象は確認していません。)
検索キーワード：「Android sdk bug 25.2」
現象：Emulator(AVD)がクラッシュする。
影響を受けるバージョン：Android SDK Tools: ～25.2.2
※25.3.xは、別の問題が起きている模様。
影響を受けないと思われるバージョン：
Android SDK Tools: 25.2.3 (？)
※25.2.3で再現しないという報告があった。
ただし、リリースノートでは、25.2.4、25.2.5にもエミュレータのバグフィックスが入っている。
また、25.3.0で、エミュレータ関連の大きな変更があったので、かなり注意した方が良さそうです。(「Android sdk bug 25.3」で検索すると、色々あるようなので。)

資料1 SDK Tools Release Notes
SDK Tools, Revision 25.3.0 (March 2017)
Changes:
Android Emulator is removed from this package and moved to a different SDK directory. See the new Android Emulator Release Notes. This change is backward compatible with older Android Studio versions.
資料2 Emulator Release Notes
Revision 25.3.0 (March 2017)
Minor revision 25.3.1 (March 2017)Fixed a crash occurring on some GPU configurations by disabling GLAsyncSwap by default. This feature was added in 25.3.0 to improve frame timing and frames per second for games and video, but causes the emulator to fail on some unknown machine configurations. You can manually enable it by opening the android_sdk/emulator/lib/advancedFeatures.ini file and setting GLAsyncSwap = on.
資料3 Stackoverflow - Emulator on Android Studio doesn't start after SDK tools update to 25.3.1
Q:
After updating my Android SDK tools today to 25.3.1, the emulator won't run anymore.
A:
・・・Finally as a workaround, I just copied all of the system files from the SDK system images directory into the AVD directory:
・・・After that the emulator started right up. It's not ideal, but this was blocking my development so I had to get the emulator up and running again. I hope someone else will be able to figure out what broke in the configuration.
