将模块从GIT添加到Android Studio会引发“未指定buildToolsVersion”错误

Question

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

So I checked it out into a local folder, added it to my project with the "New->Import Module Dialog in Android Studio.

Then I added those 2 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 getting the error

Error:Cause: buildToolsVersion is not specified.

If I do not add the first line to the gradle file (do it exactly like the color picker description said) then I get

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

How to fix it?

Answer 1

Follow the steps :

Open the build.gradle file of color picker module

so in your case add these lines to build.gradle file of colorpicker module

compileSdkVersion 24
buildToolsVersion '24.0.2'

Answer 2

请把你的buildToolVersion放在双引号中

buildToolsVersion "23.0.2"
