最近把android studio升級到了3.2，出了一堆問題，主要就是無法更新無法下載之類的。

包括出現的：

由於已經解決無法復現。
解決方法：
開啟C:/Users/(使用者名稱)/.gradle/gradle.properties
把代理的配置註釋掉，例如：

## For more details on how to configure your build environment visit

#
# Specifies the JVM arguments used for the daemon process.
# The setting is particularly useful for tweaking memory settings.
# Default value: -Xmx1024m -XX:MaxPermSize=256m
# org.gradle.jvmargs=-Xmx2048m -XX:MaxPermSize=512m -XX:+HeapDumpOnOutOfMemoryError -Dfile.encoding=UTF-8
#
# When configured, Gradle will run in incubating parallel mode.
 

# This option should only be used with decoupled projects. More details, visit

然後重啟studio，Build–>Make Project一下，則會自動下載該下載的東西。
