android - 混合版本会导致 Firebase 中的运行时崩溃吗？

Question

以下是我的 gradle 文件:

apply plugin: 'com.android.application'
apply plugin: 'realm-android'
apply plugin: 'io.fabric'


android {
    compileSdkVersion 27
    buildToolsVersion "27.0.3"
    defaultConfig {
        applicationId "???"
        minSdkVersion 21
        targetSdkVersion 27
        versionCode 4
        versionName "1.02"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {

            minifyEnabled true
            shrinkResources true
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }

    realm {

        syncEnabled = true
    }
}

dependencies {

    implementation fileTree(include: ['*.jar'], dir: 'libs')
    implementation project(':EBS')
    implementation 'com.android.support:appcompat-v7:27.1.1'
    implementation 'com.android.support:design:27.1.1'
    implementation 'com.android.support.constraint:constraint-layout:1.1.2'
    implementation 'com.android.support:gridlayout-v7:27.1.1'
    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'
    implementation 'com.afollestad.material-dialogs:commons:0.9.6.0'
    implementation 'com.android.support:cardview-v7:27.1.1'
    implementation 'com.android.support:recyclerview-v7:27.1.1'
    implementation 'com.squareup.retrofit2:retrofit:2.4.0'
    implementation 'com.squareup.retrofit2:converter-gson:2.4.0'
    implementation 'com.daimajia.swipelayout:library:1.2.0@aar'

    implementation 'com.google.firebase:firebase-messaging:17.1.0'
    implementation 'com.google.firebase:firebase-core:16.0.1'

    implementation 'com.crashlytics.sdk.android:crashlytics:2.9.4'
    implementation 'com.github.amlcurran.showcaseview:library:5.4.3'
}

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

//顶级构建文件，您可以在其中添加所有子项目/模块通用的配置选项。

buildscript {

    repositories {
        google()
        jcenter()
        maven {

            url 'https://maven.fabric.io/public'

        }
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.1.3'
        classpath 'com.jfrog.bintray.gradle:gradle-bintray-plugin:1.7.3'
        classpath "io.realm:realm-gradle-plugin:5.4.1"
        classpath 'com.google.gms:google-services:4.0.2'
        classpath 'io.fabric.tools:gradle:1.25.4'
        classpath 'com.google.android.gms:strict-version-matcher-plugin:1.0.3'
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        google()
        jcenter()
        maven {

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

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

这里我在我的项目中添加了 firebase core 和 firebase messaging，但是我面临着

"All gms/firebase libraries must use the exact same version specification (mixing versions can lead to runtime crashes). Found versions 17.1.0, 16.2.0, 16.1.1, 16.0.1, 16.0.0, 15.0.1. Examples include com.google.firebase:firebase-messaging:17.1.0 and com.google.firebase:firebase-iid:16.2.0 less... (⌘F1) There are some combinations of libraries, or tools and libraries, that are incompatible, or can lead to bugs. One such incompatibility is compiling with a version of the Android support libraries that is not the latest version (or in particular, a version lower than your targetSdkVersion.)"

你能帮我解决这个问题吗？

Answer 1

我也遇到了同样的问题，我是如何解决这个问题的:

由于 gradle 发出警告混合版本会导致运行时崩溃，并且 gradle 将给出示例 include 以便:

All gms/firebase libraries must use the exact same version specification (mixing versions can lead to runtime crashes). Found versions 17.1.0, 16.2.0, 16.1.1, 16.0.1, 16.0.0, 15.0.1. Examples include com.google.firebase:firebase-messaging:17.1.0 and com.google.firebase:firebase-iid:16.2.0 less... (⌘F1) There are some combinations of libraries, or tools and libraries, that are incompatible, or can lead to bugs. One such incompatibility is compiling with a version of the Android support libraries that is not the latest version (or in particular, a version lower than your targetSdkVersion.)

正如你在上面的语句中看到的

Examples include com.google.firebase:firebase-messaging:17.1.0 and com.google.firebase:firebase-iid:16.2.0 less...

所以只需添加任何引起版本冲突并由 gradle 提到的依赖项

implementation com.google.firebase:firebase-messaging:17.1.0
implementation  com.google.firebase:firebase-iid:16.2.0

添加依赖项后，gradle 可能会包含更多依赖项，因此也添加这些依赖项。

注意:Gradle 显示此警告是因为您正在使用一些正在使用其他的第三方库
