解决gradle DSL method not found: android()问题

将项目导入AS中，发现了这个问题，Google之，按照下面这篇文章找到了解决方法。

I’ve been using Android Studio for about a year, since I started to learn how to develop mobile applications. For me, AS is way better than Eclipse: everything works so much better.

I used to download open source projects (mostly from GitHub) just to explore the code and learn, but since the release of the AS 1.0 RC version, the IDE can’t import correctly my projects — specially if they was created on Eclipse.

After update the general app configs (to the latest build tools and compile SDK version, for example) and try to compile and execute, I was getting the “gradle DSL method not found: android()” error. Very strange, since I reinstalled recently Android Studio and it’s supposed to come with the latest gradle.

Note that none of this quickfixes works.

After days searching about, I realised what the problem is and how easy is to solve it.

For a unknown reason, Android Studio incorrectly adds the android() method in the top-level build.gradle file.

Note that is this build.gradle file. Usually, there’s another file with the same name inside the app folder.

Just delete the method.

//DELETE THIS LINES:

android {    compileSdkVersion 21    buildToolsVersion '21.1.2'}

Try to compile again. It should work now.
