1，Error:(1, 0) Plugin with id 'com.android.application' not found.
解决办法：
在总的工程下面添加如下gradle语句：
buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:0.12.+'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
