如果你的linux机子是32位的，那么运行android模拟器的时候会报错，如下：
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.
Android模拟器在64位系统上运行最好，所以最好的解决办法是重新安装64位的linux系统，如果暂时重装系统比较麻烦的话，有以下两种方法来解决：
1. 在你要运行的个工程右击->Run as -> Run configuration->Android application-> emulator ， 滚动条拉到最后，找到commandline输入框，输入"-force-32bit"，然后apply即可。
2. 配置环境变量，加上ANDROID_EMULATOR_FORCE_32BIT=true
