问题

I got this error after update my Gradle (I have also added maven{jitpack.io} and geofirestore dependencies at the same of updating Gradle) :

Android resource linking failed

How can I solve this?

Here my Project build gradle:

buildscript {

    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.2.0'


        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
        classpath 'com.google.gms:google-services:4.0.2'
    }
}

allprojects {
    repositories {
        google()
        jcenter()

        maven { url 'https://jitpack.io' }
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

and my Module build gradle:

    apply plugin: 'com.android.application'

android {
    compileSdkVersion 27
    defaultConfig {
        applicationId "com.how2ride.how2ride"
        minSdkVersion 21
        targetSdkVersion 27
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
        resConfigs "en", "fr"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    //noinspection GradleCompatible
    implementation 'com.android.support:appcompat-v7:27.1.1'
    implementation 'com.android.support:support-v4:27.1.1'
    implementation 'com.android.support:design:27.1.1'
    implementation 'com.google.android.gms:play-services-maps:15.0.1'
    implementation "com.google.android.gms:play-services-location:15.0.1"
    implementation 'com.google.firebase:firebase-ads:15.0.1'
    implementation 'com.google.firebase:firebase-core:16.0.3'
    implementation 'com.firebaseui:firebase-ui-auth:4.1.0'
    implementation 'com.google.firebase:firebase-auth:16.0.3'
    implementation 'com.google.firebase:firebase-firestore:17.1.0'
    implementation 'com.github.imperiumlabs:GeoFirestore-Android:v1.1.1'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.2'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
}

apply plugin: 'com.google.gms.google-services'

I have the last version of android studio and my project worked perfectly before upgrading my gradle...

回答1:

Change the compileSdkVersion to:

compileSdkVersion 28

These attributes were added in this version. Check here, here and here

回答2:

Downgrade your gradle version to 3.1.4 i.e classpath 'com.android.tools.build:gradle:3.1.4'

回答3:

Downgrade gradle on 3.1.4 . Check for your build.gradle(Modele:App) file:

    classpath 'com.android.tools.build:gradle:3.1.4'

The project was built :)

回答4:

check for your graddle-wrapper.properties file

Sun Jul 08 23:40:54 KST 2018
distributionBase=GRADLE_USER_HOME
distributionPath=wrapper/dists
zipStoreBase=GRADLE_USER_HOME
zipStorePath=wrapper/dists
distributionUrl=https\://services.gradle.org/distributions/gradle-4.4-all.zip

check the last line the gradle version file url

回答5:

try this code in this build.gradle

 classpath 'com.android.tools.build:gradle:3.1.4'

回答6:

was facing this issue today after updating to the new gradle 3.0.1 to 3.2.0 for my case i deleted the ids.xml file in values folder (it was useless in the project) work for me

回答7:

Set your classpath to the current build gradle and sync your project.There seems to be an issue with Android studio version 3.2. When prompted to update gradle also update the classpath values.
