Could not find method android() for arguments

问题

I've been trying to import a project to Android Studio and this is where I am stuck, there is a similar question on Stack Overflow but it did not provide a solution to my particular error.

This is my error log:

C:\<some location>\build.gradle

Error:(24, 1) A problem occurred evaluating root project '<project name>'.
> Could not find method android() for arguments [build_4fli1jm76ubcnxesnhqnhie47$_run_closure3@6e71db85] on root project '<project name>'.
Information:BUILD FAILED

The Gradle sync messages are:

Error:(24, 0) Gradle DSL method not found: 'android()' Possible causes:

The project 'PoojaPeople' may be using a version of Gradle that does not contain the method. Gradle settings

The build file may be missing a Gradle plugin. Apply Gradle plugin

I'm not too sure where exactly this method android() is located. If it is the one located in Application's build.gradle file, I still don't exactly know where to go from here. Any help is appreciated.

My build.gradle is

buildscript {
    repositories {
        maven { url "http://dl.bintray.com/populov/maven" }
        mavenCentral()
    }
     dependencies {
        classpath 'com.android.tools.build:gradle:2.1.0'
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}
allprojects {
    repositories {
        maven { url "http://dl.bintray.com/populov/maven" }
        mavenCentral()

    }
}
task clean(type: Delete) {
    delete rootProject.buildDir
}

android {
    compileSdkVersion 17
    buildToolsVersion '23.0.0'
}
dependencies {
    compile files('app/libs/junit-4.12-JavaDoc.jar')
}
apply plugin: 'maven'

回答1:

You are using the wrong build.gradle file.

In your top-level file you can't define an android block.

Just move this part inside the module/build.gradle file.

android {
    compileSdkVersion 17
    buildToolsVersion '23.0.0'
}
dependencies {
    compile files('app/libs/junit-4.12-JavaDoc.jar')
}
apply plugin: 'maven'

guys. I had the same problem before when I'm trying import a .aar package into my project, and unfortunately before make the .aar package as a module-dependence of my project, I had two modules (one about ROS-ANDROID-CV-BRIDGE, one is OPENCV-FOR-ANDROID) already. So, I got this error as you guys meet:

Error:Could not find method android() for arguments [org.ros.gradle_plugins.RosAndroidPlugin$_apply_closure2_closure4@7e550e0e] on project ‘:xxx’ of type org.gradle.api.Project.

So, it's the painful gradle-structure caused this problem when you have several modules in your project, and worse, they're imported in different way or have different types (.jar/.aar packages or just a project of Java library). And it's really a headache matter to make the configuration like compile-version, library dependencies etc. in each subproject compatible with the main-project.

I solved my problem just follow this steps:

① Copy .aar package in app/libs.

② Add this in app/build.gradle file:

repositories {
    flatDir {
        dirs 'libs' //this way we can find the .aar file in libs folder
    }
}

③ Add this in your add build.gradle file of the module which you want to apply the .aar dependence (in my situation, just add this in my app/build.gradle file):

dependencies {
    compile(name:'package_name', ext:'aar')
}

So, if it's possible, just try export your module-dependence as a .aar package, and then follow this way import it to your main-project. Anyway, I hope this can be a good suggestion and would solve your problem if you have the same situation with me.

My issue was inside of my app.gradle. I ran into this issue when I moved

apply plugin: "com.android.application"

from the top line to below a line with

apply from:

I switched the plugin back to the top and violá

My exact error was

Could not find method android() for arguments [dotenv_wke4apph61tdae6bfodqe7sj$_run_closure1@5d9d91a5] on project ':app' of type org.gradle.api.Project.

The top of my app.gradle now looks like this

project.ext.envConfigFiles = [
        debug: ".env",
        release: ".env",
        anothercustombuild: ".env",
]


apply from: project(':react-native-config').projectDir.getPath() + "/dotenv.gradle"
apply plugin: "com.android.application"
