android - Building Gradle项目失败

Question

在构建项目时达到Task mergeReleaseAssets时，出现此错误com.android.build.api.transform.TransformException:

com.android.ide.common.process.ProcessException: java.util.concurrent.ExecutionException: com.android.dex.DexException: Multiple dex files define Landroid/support/v4/content/res/TypedArryUtils; See the Console for details

----我不知道是什么原因导致我的jdk8u-131我尝试了8u161，而我也不知道SDK的api级别，因为我的手机api级别是27奥利奥(Oreo)，并且没有统一，所以我没有下载Android SDK上的8.0(Oreo)，但我没有使用应用内购买功能，而是将普通广告统一

对于GoggleMobileAds，我下载了它，但是我没有在项目cuz上使用它，这伤了我的头，我使用统一的普通广告

这是控制台上的错误

在您的defaultConfig中在应用程序级别gradle中添加multiDexEnabled true。

defaultConfig {
    applicationId "your application id"
    minSdkVersion 16
    targetSdkVersion 25
    versionCode 1
    versionName "1.0"
    testInstrumentationRunner"android.support.test.runner.AndroidJUnitRunner"
    multiDexEnabled true
}
