Gradle failed to resolve library in Android Studio

Question

I want to include a library in Android Studio , but it displays error like below :

"Failed to resolve:com.lemonlab:expandable-button-menu:1.0.0"

How to fix this problem?

    apply plugin: 'com.android.application'

    android {
        compileSdkVersion 21
        buildToolsVersion '21.1.2'

        defaultConfig {
            applicationId "ayowes.com.newecampus"
            minSdkVersion 15
            targetSdkVersion 21
            versionCode 1
            versionName "1.0"
        }
        buildTypes {
            release {
                minifyEnabled false
                proguardFiles getDefaultProguardFile('proguard-android-ptimize.txt'), 'proguard-rules.txt'
            }
        }
    }

    dependencies {
        compile fileTree(dir: 'libs', include: ['*.jar'])
        compile 'com.android.support:appcompat-v7:21.0.3'
        compile 'com.google.android.gms:play-services:6.5.87'
        compile 'com.lemonlab:expandable-button-menu:1.0.0'
        compile files('libs/pinchzoom.jar')
    }

in gradle , i type compile 'com.lemonlab:expandable-button-menu:1.0.0' , after that i sync and display error "Failed to resolve:com.lemonlab:expandable-button-menu:1.0.0'" — Feb 13 '15 at 6:10
Not sure but try this File -> Invalidate caches/restart-> choose Invalidate caches/restart. — Feb 13 '15 at 6:34

To be able to use a lib project you need to include it in your application's settings.gradle add:

include '..:ExpandableButtonMenu:library'

and then in your build.gradle add:

compile project(':..:ExpandableButtonMenu:library')

place ExpandableButtonMenu project along side your own (same folder)

see this How to build an android library with Android Studio and gradle? for more details.

You go File->Settings->Gradle Look at the "Offline work" inbox, if it's checked u uncheck and try to sync again I have the same problem and i try this , the problem resolved. Good luck !

Thanks! If only gradle said "cannot resolve but you are in offline mode if you hadn't realised". – David Amey May 19 '15 at 14:33

I had the same problem, first thing came on mind was about repositories. So i checked build.gradle file for the whole project and added below lines, synchronized the gradle with project and problem solved! Hope will help someone else.

allprojects {
    repositories {
        jcenter()
    }
}

Check to see if your gradle is offline. Preferences-ProjectSettings-Gradle. If you're trying to add a library while offline, you'll see that error. Also, try Build-Clean, it may provide you with more detail.

Well, it's co.lemonlabs, you have a typo in your build.gradle:

compile 'co.lemonlabs:expandable-button-menu:1.0.0'

Try this

Clean project
Invalidate cache and restart studio
Check android SDK path is proper
Check is there any error in any of your resource file
