I want to use Google architecture components in my app, but after updating android studio to version 3.1.1 when I add android.arch.lifecycle:extensions:1.1.1 dependency into app.gradle file, it will show Failed to resolve: support-fragment
My gradle version is 4.4

enter image description here

This is app gardle:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 27
    defaultConfig {
        applicationId "ir.apptori.myapplication"
        minSdkVersion 17
        targetSdkVersion 27
        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 'com.android.support:appcompat-v7:27.1.1'
    implementation 'com.android.support.constraint:constraint-layout:1.0.2'
    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'

    implementation "android.arch.lifecycle:extensions:1.1.1"
}

Please guid me how to fix it, Thanks

Solution

  • I had a similar error and changing the repositories order so that google() comes before jcenter() fixed it.

    I had to change the order for the repositories within buildscript and allprojects in the top level build.gradle file.
