Java – parameter org.org not found gradle. api. Project method (Android)

I got a bug. When I tried to compile my project in the studio, I had searched a lot without a real solution

Error: (17,0) can't be in type org gradle. api. Find the method Android () of the parameter [build_a7zf1o8ge4ow4uolz6kqzw5ov $_run_closure2 @ 19201053] in the root project 'booksstudiodir' of project

This is an example of my build / gradle file

buildscript {
repositories {
    maven { url 'https://maven.fabric.io/public' }
}

dependencies {
    classpath 'io.fabric.tools:gradle:1.+'
  }
 }
  apply plugin: 'com.android.application'
apply plugin: 'io.fabric'


android {
compileSdkVersion 21
buildToolsVersion "23.0.1"

defaultConfig {
    applicationId "com.peade.time"
    minSdkVersion 10
    targetSdkVersion 13
}
signingConfigs {
    release {
        storeFile file("/home/bestman/Desktop/mkey/key")
        storePassword "androidkeys"
        keyAlias "peade"
        keyPassword "yes1234"
    }
}
buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'),'proguard-rules.txt'
        signingConfig signingConfigs.release
     }
  }
}
  repositories {
    maven { url 'https://maven.fabric.io/public' }
    mavenCentral()
 }
dependencies {
   compile 'com.edmodo:cropper:1.0.1'
   compile 'com.android.support:support-v4:21.0.3'
   compile 'com.itextpdf:itextpdf:5.5.6'
   //    compile files('libs/commons-lang3-3.3.2.jar')
   compile files('libs/drop@R_8_2419@-android-sdk-1.6.1.jar')
   //    compile files('libs/httpmime-4.0.3.jar')
   compile files('libs/json_simple-1.1.jar')
   compile files('libs/picasso-2.5.2.jar')
   compile('com.crashlytics.sdk.android:crashlytics:2.5.2@aar') {
    transitive = true;
   }
   compile project(':owncloud')
 }

Solution

There are two build Gradle file One is the top holder, the other is the module holder

The following is an example

Top level build gradle： https://github.com/nickbutcher/plaid/blob/master/build.gradle

Module build gradle： https://github.com/nickbutcher/plaid/blob/master/app/build.gradle

The Android block should be in the build.exe of the module In gradle I guess you have to build at the top Android blocks are defined in gradle, which leads to errors
