Question

我正在按照教程（link）将图像上传到Firebase数据库但收到以下错误。我重新检查了gradle依赖项并启用了multidex支持，但错误仍然存在

    compile 'com.android.support:multidex:1.0.0'

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

请告诉我这里做错了什么！

Answer 1

现在问题是，您在gradle的依赖项中使用了不同的版本所以改变这个

compile 'com.google.firebase:firebase-database:10.0.0'
testCompile 'junit:junit:4.12'
compile 'com.firebase:firebase-client-android:2.3.1'
compile 'com.google.firebase:firebase-auth:9.2.1'
compile 'com.google.firebase:firebase-storage:9.2.1'
compile 'com.android.support:multidex:1.0.0'

到这个

compile 'com.google.firebase:firebase-database:10.0.1'
testCompile 'junit:junit:4.12'
compile 'com.firebase:firebase-client-android:2.3.1'
compile 'com.google.firebase:firebase-auth:10.0.1'
compile 'com.google.firebase:firebase-storage:10.0.1'
compile 'com.android.support:multidex:1.0.0'

另外一件事是，现在com.firebae:firebase-client-android已被弃用，因此您需要将其替换为com.google.firebase:firebase-database:10.0.1，以下是https://firebase.google.com/support/guides/firebase-android的文档

Answer 2

如果您正在寻找本机项目的解决方案，请确保在不同模块中使用相同的版本，并用一些最新的可用版本替换“ +”。

Answer 3

在实施原生广告时，我遇到了类似的问题，并杀死了将近4个小时...

最后，我发现不同模块中的com.google.android.gms：play-services-ads版本不同（“ 17.1.1”和“ 12.0.0”）。

将所有版本更改为17.1.1后，它解决了我的问题。

Answer 4

尝试在项目bundle.gradle文件中添加这样的内容

allprojects {
    repositories {
    //start here
    configurations.all {
 resolutionStrategy.eachDependency { DependencyResolveDetails details ->
   def requested = details.requested
       if (requested.group == 'com.google.android.gms') {
          details.useVersion '12.0.1'
       }
       if (requested.group == 'com.google.firebase') {
          details.useVersion '12.0.1'
         }
       }
     }
    //end
     jcenter()
       maven {
         url "https://maven.google.com"
       }
     }
 }

将以下依赖项添加到Module / bundle.gradle

implementation 'com.google.firebase:firebase-core:16.0.1'
implementation 'com.firebaseui:firebase-ui-auth:3.3.0'

Answer 5

大多数情况下，问题出在问题上。我遇到了类似的问题，直到我将模块应用程序的firebase-（storage / auth / database）构建gradle更改为例如（com.google.firebase：firebase-storage：16.1.0，com.google.firebase：firebase-auth：16.1.0，com.google.firebase：firebase-database：16.1.0）
