我不明白为什么我的桌面突然出现这样的问题。虽然我已经14.04 LTS Ubuntu即64 位，但仍然出现这样的错误。虽然它运行正常，直到昨天。请帮帮我。
Cannot launch AVD in emulator.
Output:
ERROR: 32-bit Linux Android emulator binaries are DEPRECATED, to use them
you will have to do at least one of the following:
- Use the '-force-32bit' option when invoking 'emulator'.
- Set ANDROID_EMULATOR_FORCE_32BIT to 'true' in your environment.
Either one will allow you to use the 32-bit binaries, but please be
aware that these will disappear in a future Android SDK release.
Consider moving to a 64-bit Linux system before that happens.
