所有Firebase依赖项的版本都相同，启动后应用仍然崩溃

我注意到这是一个很常见的问题，因此我做了一些研究，并试图自己解决这个问题，但没有任何积极的结果。因此，如果有人对解决这个问题有任何想法，我将非常感激。我已经坚持了几个小时。

我查看了以下线程：

  1. Firebase database dependecny crashes app-我发现我的所有依赖项版本都应该相同。
  2. Android app crashes-在此线程中，他们建议我应根据google official website使用最新版本。
  3. 还有here我发现了相同的建议-版本应该相同，清理并重建项目等。

我了解的是问题所在： 依赖项不兼容。

注意：我的应用仅在firebase-realtime数据库上运行良好。添加firebase-auth后，它立即崩溃（在Huawei P9 lite上未在仿真器上测试）。

我尝试过的事情：

1）使所有依赖项为最新版本。它无法正常工作-启动后应用仍然崩溃。

implementation 'com.google.firebase:firebase-core:16.0.8'

implementation 'com.google.firebase:firebase-database:16.1.0'

implementation 'com.google.firebase:firebase-auth:16.2.0'

2）基于此link（即16.0.5）将依赖项降级为它们共有的最接近版本。

implementation 'com.google.firebase:firebase-core:16.0.5'

implementation 'com.google.firebase:firebase-database:16.0.5'

implementation 'com.google.firebase:firebase-auth:16.0.5'

3）当我尝试通过工具管理器添加firebase-auth时，     插入了'com.google.firebase:firebase-auth:16.0.3'导致此错误：

ERROR: In project 'app' a resolved Google Play services library dependency depends on another at an exact version (e.g. "[15.0. 1]", but isn't being resolved to that version. Behavior exhibited by the library will be unknown.

这是我的应用程序级别gradle文件的样子：

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

android {
    compileSdkVersion 28
    defaultConfig {
        applicationId "com.example.test123"
        minSdkVersion 21
        targetSdkVersion 28
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation 'com.android.support:appcompat-v7:28.0.0'
    implementation 'com.android.support.constraint:constraint-layout:1.1.3'

    implementation 'com.android.support:animated-vector-drawable:28.0.0'
    implementation 'com.android.support:support-media-compat:28.0.0'
    implementation 'com.android.support:support-v4:28.0.0'

    implementation 'com.google.firebase:firebase-core:16.0.5'

    implementation 'com.google.firebase:firebase-database:16.0.5'

    implementation 'com.google.firebase:firebase-auth:16.0.5'

    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'

这是我的gradle文件：

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    repositories {
        google()
        jcenter()
    }
    dependencies {

        // Android Gradle Plugin
        classpath 'com.android.tools.build:gradle:3.3.2'

        // Google Services Plugin
        classpath "com.google.gms:google-services:4.2.0"

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        google()
        jcenter()

    }
}

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

问题可能出在您的设备上，它可能没有最新的Google Play服务来支持您的应用所请求的版本。

尝试在您的设备中更新您的Google Play服务，或更改为其他设备并在其中进行测试。

答案 1 :(得分：0)

尝试一下，它可能会起作用。

implementation 'com.google.firebase:firebase-core:16.0.1'
implementation 'com.google.firebase:firebase-database:16.0.1'
implementation 'com.google.firebase:firebase-auth:16.0.1'

答案 2 :(得分：0)

当我们使用多个库，其中某些库已经包含在某些库中，但版本不同时，我们遇到了这类问题。为此，您可以强制gradle在任何地方使用该库的单个版本

configurations.all {
 resolutionStrategy {
   force "com.google.firebase:firebase-core:${VERSION_XYZ}”
   force "com.google.firebase:firebase-database:${VERSION_ABC}”
 }}
 dependencies {
   // ... all dependencies here...
 }

就像这样，对每个库都执行此操作，然后在gradle文件中定义它，这可能会对您有所帮助。

尝试一下，它将对您有用。编码愉快：）
