android - 我在 Android studio 3.0 Beta 5 中运行应用程序时遇到 Multidex 问题

Question

我已点击此解决方案的各种链接，但没有任何效果。 以下是错误:

java.lang.RuntimeException: com.android.builder.dexing.DexArchiveMergerException: Unable to merge dex

我还启用了 multidex 并在 build.gradle 文件底部添加了 google services 插件。这是 build.gradle 编译器依赖项:

compile fileTree(include: '*.jar', dir: 'libs')
compile files('libs/universal-image-loader-1.9.5.jar')
compile('com.crashlytics.sdk.android:crashlytics:2.6.8@aar') {
    transitive = true;
}

compile 'com.android.support:design:26.0.1'
compile 'com.android.support:mediarouter-v7:26.0.1'
compile 'com.android.support:appcompat-v7:26.0.1'

Android 5.0(API 级别 21)之前的平台版本使用 Dalvik 运行时来执行应用程序代码。默认情况下，Dalvik 将应用程序限制为每个 APK 的单个 classes.dex 字节码文件。为了绕过这个限制，您可以将 multidex 支持库添加到您的项目中:

添加如下依赖

  android {
    defaultConfig {
        ...
        minSdkVersion 15 
        targetSdkVersion 26
        multiDexEnabled true
    }
    ...
}

dependencies {
  compile 'com.android.support:multidex:1.0.1'
}



<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.myapp">
    <application
            android:name="android.support.multidex.MultiDexApplication" >
        ...
    </application>
</manifest>

如果您确实覆盖了 Application 类但无法更改基类，那么您可以覆盖 attachBaseContext() 方法并调用 MultiDex.install(this) 以启用 multidex:

public class MyApplication extends SomeOtherApplication {
  @Override
  protected void attachBaseContext(Context base) {
     super.attachBaseContext(base);
     MultiDex.install(this);
  }
}
