Unable to resolve dependency Android Studio 3.0

Question

It's good to have a Updated Android Studio 3.0. But I am facing a problem with Android Studio 3.0, I just created a new project in Android Studio 3.0. Then I got some error

I solved these by changing dependencies to latest version and issues solved.

But, when I added a dependency of facebook account-kit sdk com.facebook.android:account-kit-sdk:4.+

I am getting following errors-:

Error:Unable to resolve dependency for ':app@debug/compileClasspath': Could not resolve com.facebook.android:account-kit-sdk:4.+. Open File

build.gradle(app)

apply plugin: 'com.android.application'  apply plugin: 'kotlin-android'  apply plugin: 'kotlin-android-extensions'  android {     compileSdkVersion 26     defaultConfig {         applicationId "ultimate.devil.logintest"         minSdkVersion 15         targetSdkVersion 26         versionCode 1         versionName "1.0"         testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"     }     buildTypes {         release {             minifyEnabled false             proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'         }     } }  dependencies {     implementation fileTree(dir: 'libs', include: ['*.jar'])     implementation"org.jetbrains.kotlin:kotlin-stdlib-jre7:$kotlin_version"     implementation 'com.android.support:appcompat-v7:26.1.0'     implementation 'com.android.support.constraint:constraint-layout:1.0.2'     compile 'com.facebook.android:account-kit-sdk:4.+'     testImplementation 'junit:junit:4.12'     androidTestImplementation 'com.android.support.test:runner:1.0.1'     androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.1' } 

NOTE -:

• I am following Facebook Developers Docs

• I have tried by changing compile to implementation

• I have also tried changing com.facebook.android:account-kit-sdk:4.+ to com.facebook.android:account-kit-sdk:4.11.0 and com.facebook.android:account-kit-sdk:4.27 by googling latest version of Facebook Account-Kit SDK

• I have also tries StackOverFlow Answers with possible with same problem. But no one help me

Answer 1

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,

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     } }
