Updating my Gradle build version did the trick for me.
更新我的 Gradle 构建版本对我有用。
Old:
老的：
classpath 'com.android.tools.build:gradle:1.0.0'
New:
新的：
classpath 'com.android.tools.build:gradle:2.2.3'
Edit: Since this answer is still being used frequently, note that Gradle 2.2.3 can probably be substituted with any newer version of Gradle. This version just happened to be the version I was using when I originally answered the question.
编辑：由于这个答案仍然经常被使用，请注意 Gradle 2.2.3 可能会被任何较新版本的 Gradle 替换。这个版本恰好是我最初回答问题时使用的版本。

I have this problem a lot when I try to open older projects for the first time. It seems that I just need to update the classpath under build.gradle:
当我第一次尝试打开旧项目时，我经常遇到这个问题。看来我只需要更新build.gradle下的classpath：
In my case the old version was:classpath 'com.android.tools.build:gradle:1.3.0'
and I updated to:classpath 'com.android.tools.build:gradle:2.3.2'
在我的情况下，旧版本是：classpath 'com.android.tools.build:gradle:1.3.0'
并且我更新为：classpath 'com.android.tools.build:gradle:2.3.2'
Sync the gradle and it should compile.
同步gradle，它应该可以编译。
