找不到参数 org.gradle.api.Project 的方法 android()

Question

Getting a bug, when I try to compile my project in studio , i have search quite a bit with no real solution to it

Error:(17, 0) Could not find method android() for arguments [build_a7zf1o8ge4ow4uolz6kqzw5ov$_run_closure2@19201053] on root project 'booksStudioDir' of type org.gradle.api.Project.

This is a sample 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/dropbox-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')
 }

Answer 1

There are two build.gradle files. One is in the top-level holder, and the other is in module holder.

Below is an example.

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

module's build.gradle:
https://github.com/nickbutcher/plaid/blob/master/app/build.gradle

The android block should be in module's build.gradle . I guess you must have defined the android block in top-level build.gradle which is causing the error.

Answer 2

I had same problem if your android block is in module's build.gradle and use google services, just add these 2 lines before android block:

 apply plugin: 'com.android.application' apply plugin: 'com.google.gms.google-services'

Answer 3

Invalidate Cache and restart

Go to : File/Invalidate Cache/Click on Invalidate and Restart This should solve your problem for you.
