在类型为org.gradle.api.Project的根项目'..'上找不到参数[build ..]的方法android（）

Question

The following shows up when I'm tryig to work:

Could not find method android() for arguments [build_9cxkoz5xxe5p8ydg2a1ig2k7b$_run_closure1@7b0f017] on root project 'dangerous-forest-game-android' of type org.gradle.api.Project.

I have been looking for a solution to my problem, but I found my syntax is too different. Here is the code of my android() function :

android {
buildToolsVersion "19.1.0"
compileSdkVersion 20
  sourceSets {
    main {
        manifest.srcFile 'AndroidManifest.xml'
        java.srcDirs = ['src']
        aidl.srcDirs = ['src']
        renderscript.srcDirs = ['src']
        res.srcDirs = ['res']
        assets.srcDirs = ['assets']
    }
    instrumentTest.setRoot('tests')
  }
}

You have to use the android DSL only in your app/build.gradle file and not in the root/build.gradle file.

Also you have to apply the android plugin in the app/build.gradle file before using it. Check the official doc .

/**
 * The first line in the build configuration applies the Android plugin for
 * Gradle to this build and makes the android block available to specify
 * Android-specific build options.
 */

apply plugin: 'com.android.application'

/**
 * The android block is where you configure all your Android-specific
 * build options.
 */

android {
  //.....
}
