React-Native (Android) - 任务 ':app:transformClassesWithMultidexlistForRelease' 执行失败

Question

将库 react-native-fcm 更新到版本 16（现在支持 Android 8）后，出现以下错误：

Execution failed for task ':app:transformClassesWithMultidexlistForRelease'.
> com.android.build.api.transform.TransformException: Error while generating the main dex list.

知道如何解决这个问题吗？

project/build.gradle：

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

buildscript {
    repositories {
        jcenter()
        maven {
            url 'https://maven.google.com/'
            name 'Google'
        }
        google()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.1.2'
        classpath 'com.google.gms:google-services:4.0.2'
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        // Add jitpack repository (added by tipsi-stripe)
        maven { url "https://jitpack.io" }
        mavenLocal()
        jcenter()
        google()
        maven {
            // All of React Native (JS, Obj-C sources, Android binaries) is installed from npm
            url "$rootDir/../node_modules/react-native/android"
        }
        configurations.all {
            resolutionStrategy {
                force 'com.facebook.android:facebook-android-sdk:4.28.0'
                force 'com.android.support:support-v4:27.1.0'
                force 'com.android.support:design:27.1.0'
            }
        }
        maven {
            url 'https://maven.google.com/'
            name 'Google'
        }
    }
}

subprojects {
    if (project.name.contains('react-native-image-picker') || 
        project.name.contains('react-native-vector-icons')) {
        buildscript {
            repositories {
                jcenter()
                maven { url "https://dl.bintray.com/android/android-tools/"  }
            }
        }
    }
}

还有我的project/app/build.gradle：

Answer 1

我认为添加multiDexEnabled = true 是不够的。 尝试将此行添加到您的 app/build.gradle 文件中：

implementation 'com.android.support:multidex:1.0.3'

你的 Application 类（如果你有的话）应该是这样的：

public class App extends MultiDexApplication {
    ...
}

或者像这样：

public class App extends Application {

    @Override
        public void onCreate() {
            super.onCreate();
            MultiDex.install(this);
    }
}

希望对你有帮助。
