无法更新

重装了Android Studio，装的是2.3的版本，但是无法在线升级。

提示的大概意思是：无法删除/opt/android-studio/lib/rt/xxxxx.jar中的某一个文件

这句话让我想起了这个错误：

Studio does not have write access to /opt/android-studio. Please run it by a privileged user to update

没有权限，不能操作相应的文件夹。

执行以下命令，不要在root环境下执行

sudo chown -R $USER:$USER /opt/android-studio

这个样子，就可以了。

模拟器启动不了

解决:

sudo apt-get install lib64stdc++6:i386
sudo apt-get install mesa-utils

cd /opt/android-sdk/emulator/lib64
mv libstdc++/ libstdc++.bak
ln -s /usr/lib64/libstdc++.so.6  libstdc++

然后启动模拟器就可以了
