错误：将字节码转换为dex时出错：原因：com.android.dex.DexException：多个dex文件定义了Landroid / arch / lifecycle / LiveData $ LifecycleBoundObserver;

我的gradle文件

android {
compileSdkVersion 27
defaultConfig {
applicationId "com.ayoubdesigner101.Sinbad.sealling"
minSdkVersion 19
targetSdkVersion 27
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
multiDexEnabled true
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}

dependencies {
implementation fileTree(include: ['*.jar'], dir: 'libs')

implementation 'com.android.support:appcompat-v7:27.1.1'
implementation 'com.android.support.constraint:constraint-layout:1.1.0'

compile 'de.hdodenhof:circleimageview:2.2.0'
implementation 'com.github.bumptech.glide:glide:4.6.1'
compile 'com.firebase:geofire-android:2.1.1'
}

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

**这是我得到的错误**

Answer 1

您需要upgrade your Firebase Ui个依赖项以及GeoFire

一旦你这样做，ensure compatibles between it and the other Google and Firebase versions

而不是:play-services:11.0.4，请compile the specific dependencies of Google Play you actually are going to use。这种依赖性就是它们的全部，它会减慢你的构建，增加你不会使用的库。

如果您已将任何JAR文件添加到libs文件夹中，通常也会出现此错误。对于上面提到的类，JAR必须是一个android支持库，例如Android Architecture

将字节码转换为dex：原因：com.android.dex.DexException：多个dex文件定义
