最近打算在Linux上开发，选择了Deepin，挺不错的。
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
