无法组装安卓应用：多个 dex 文件定义 Landroid/support/coreui/R$string;由于格拉德尔

Question

我对我的Android项目有问题。在将classpath 'com.android.tools.build:gradle:3.0.0-beta2'更新为classpath 'com.android.tools.build:gradle:3.0.0-beta4'和将Gradle包装器从gradle-4.1-rc-1-all.zip更新为gradle-4.1-all.zip

之后，这个问题似乎发生了。

Multidex已启用，并且正在按预期工作。

当我在AVD上运行应用程序时，根本没有问题，但是当尝试assemble时，我有以下输出

AGPBI: {"kind":"error","text":"Error converting bytecode to dex:nCause: com.android.dex.DexException: Multiple dex files define Landroid/support/coreui/R$string;","sources":[{}],"original":"UNEXPECTED TOP-LEVEL EXCEPTION:ncom.android.dex.DexException: Multiple dex files define Landroid/support/coreui/R$string;n","tool":"Dex"}

i可以检查依赖项，并且使用了一个版本的core-ui（support-core-ui：26.0.1）。

我要搜索特定错误，但找不到解决方案。

有什么方法可以解决此问题？

edit ：（已解决）

毕竟，它与Gradle根本没有关系。这是由于滑行的某些问题。通过将@AAR添加到依赖项中来解决该问题。

Answer 1

刚刚启用多透视如下：

android {    
  defaultConfig {
    // Enabling multidex support.
    multiDexEnabled true
  }  
}
dependencies {
   compile 'com.android.support:multidex:1.0.0'
}

创建一个类似这样的类

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

现在在您的清单文件中添加此

<application
    android:name=".Multi_Dex"
    android:allowBackup="true"
    android:icon="@drawable/logo"
    android:label="@string/app_name"
    android:supportsRtl="true"
    android:theme="@style/AppTheme">
