执行aapt时出现类型错误：无法运行程序/opt/android sdk linux/build tools/19.0.1/aapt"；：java.io.IOException

每当我在一些更改后第二次尝试运行android项目时，我都会遇到这个错误。如果我关闭模拟器，错误就会消失。但每次关闭emulator都不是一个可行的解决方案。我该怎么做才能解决这个问题

Hint: On 64-bit systems, make sure the 32-bit libraries are installed: 
sudo apt-get install ia32-libs  my_project      line 1  Android ADT Problem

      check whether ia32-libs installed or not in ubuntu by following command
      dpkg --get-selections ia32-libs
      if you get
      ia32-libs                 install
      then it is installed otherwise you have to install it.
