2、下载对应的增量jar包
win: https://dl.google.com/android/studio/patches/AI-你的版本-最新版本-patch-win.jar
linux:https://dl.google.com/android/studio/patches/AI-你的版本-最新版本-patch-unix.jar
例如:https://dl.google.com/android/studio/patches/AI-162.4069837-181.5540.7.32.5056338-patch-unix.jar

cd /opt/Android/android-studio
java -classpath AI-171.4408382-173.4907809-patch-unix.jar com.intellij.updater.Runner install .
