Java – Adding modules from GIT to Android Studio throws a “buildToolsVersion is not specified” error

I want to include this Color Picker into my Android Studio project.

So I checked it out to a local folder and added it to my project using the “New-> Import Module Dialog in Android Studio”.

Then I add these two lines to my app.gradle file

apply plugin: 'com.android.application'
...
compile project(':colorpicker')

Here is the complete gradle file

apply plugin: 'com.android.application'

android {
    compileSdkVersion 24
    buildToolsVersion '24.0.2'

defaultConfig {
        applicationId "com.mydomain.myapp"
        minSdkVersion 17
        targetSdkVersion 24
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

repositories {
    maven { url "https://jitpack.io" }
}

dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    testCompile 'junit:junit:4.12'
    compile fileTree(include: ['dtp_library'], dir: 'libs')
    compile project(':libs:dtp_library')
    compile 'com.android.support:design:24.2.1'        
    compile project(':colorpicker')
}

But I keep reporting errors

Error:Cause: buildToolsVersion is not specified.

If I don’t add the first line to the gradle file (exactly as described by the color picker) then I’ll get

Error:(3, 0) Could not find method android() for arguments [build_xxxxx] on project ‘:app’ of type org.gradle.api.Project.

How to solve it?

Follow these steps:

Open the build.gradle file for the Color Picker module

So in your case, add these lines to the build.gradle file of the colorpicker module

compileSdkVersion 24
buildToolsVersion '24.0.2'
