java - 构建错误(将字节码转换为 dex 时出错)

Question

当我尝试构建 android 项目时，出现如下错误。

Error:Error converting bytecode to dex: Cause: com.android.dex.DexException: Multiple dex files define Landroid/arch/lifecycle/LiveData$LifecycleBoundObserver;

我多次搜索stackoverflow来解决这个问题，但我仍然有这个错误。

我认为这是因为一些库版本冲突造成的。但是我没有找到问题所在。

apply plugin: 'com.android.application'

android {
    compileSdkVersion 27
    defaultConfig {
        applicationId "my.app.idhere"
        minSdkVersion 19
        targetSdkVersion 27
        versionCode 4
        versionName "1.0.4"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
        manifestPlaceholders = ['appIdRedirectScheme': android.defaultConfig.applicationId]
        multiDexEnabled true
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }

    /*  This for anyone following along with the repo. Since you will have a different
  *   root URL, this code loads up a value from your gradle.properties file.
  */
    buildTypes.each {
        it.buildConfigField 'String', 'GOOGLE_API_BASE_URL', GoogleApiBaseUrl
        it.buildConfigField 'String', 'IBM_API_BASE_URL', IBMApiBaseUrl
    }

    implementation 'com.android.support:multidex:1.0.1'

}

// Add to the bottom of the file
apply plugin: 'com.google.gms.google-services'

Note: when I remove the mapbox from gradle, then error is disappeared but I need to use mapbox.

Answer 1

最后我通过添加这个 gradle 解决了这个问题。

implementation "android.arch.lifecycle:extensions:1.1.1"

添加 multidex 并清理和重建项目后，再次出现生命周期错误。

通过添加上面的 gradle 解决了这个问题。
