Unable to resolve dependency Android Studio 3.0

I am facing similar error day before yesterday. Just solved it here

Moreover, as mentioned in the latest gradle release notes , you should avoid using dynamic dependencies with version number as:

com.facebook.android:account-kit-sdk:4.+

Try to replace it with appropriate version number as 4.0.0 or latest. Hope it solves the problem.

Add matchingFallbacks = ['release', 'debug'] in the buildType that is failing to compile.

E.g. I was having an error for releaseStaging:

buildTypes {
    debug {
        buildConfigField "String", "CODEPUSH_KEY", '""'
    }
    releaseStaging {
        buildConfigField "String", "CODEPUSH_KEY", 'myKey'
        signingConfig signingConfigs.release
        matchingFallbacks = ['release', 'debug']
    }
    release {
        buildConfigField "String", "CODEPUSH_KEY", 'myKey'
        minifyEnabled enableProguardInReleaseBuilds
        proguardFiles getDefaultProguardFile("proguard-android.txt"), "proguard-rules.pro"
        signingConfig signingConfigs.release
    }
}

After some research I have solved this issue.

Step 1-:

I disable the Gradle offline work in settings.

File > Settings > Build, Execution, Deployment > Gradle > Uncheck Offline Work

Step 2-:

Then, I just changed compile 'com.facebook.android:account-kit-sdk:4.+' to api 'com.facebook.android:account-kit-sdk:4.+'

I don't know exactly why it's work. I see api in docs Reference

Now it works :)

EDIT -

Now, I am able to use both api or implementation and everything works fine.

Thanks,

Short story:

Downgrade to Gradle 4.2.1

Long story:

I was using Gradle version 4.3 based on the answer here as that question was my error. After doing that change than I started having your problem.

Downgrading to version 4.2.1 your problem went away. Now I have to go back to the previous problem.

I also had this problem while compiling my project with Android Studio 3.0 and gradle plugin 3.0.0

If I will have other problems I will post here the updates
