启用了 Multidex - 仍然无法合并 dex

Question

这是我的 build.gradle

android {
compileSdkVersion 27
defaultConfig {
    applicationId "xxxx.xxxx.xxxx"
    minSdkVersion 21
    targetSdkVersion 27
    versionCode 1
    versionName "1.0"
    testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    multiDexEnabled true
}

这是我的 Manifest.xml

 <application
    android:name="android.support.multidex.MultiDexApplication"
.../>

这些是我的依赖项

dependencies {
    implementation 'com.android.support:multidex:1.0.3'
    implementation fileTree(include: ['*.jar'], dir: 'libs')


    implementation 'com.android.support.constraint:constraint-layout:1.0.2'
    //noinspection GradleCompatible

    implementation "org.jetbrains.anko:anko:0.10.4"
    implementation "org.jetbrains.anko:anko-design:0.10.4"

    implementation 'de.hdodenhof:circleimageview:2.1.0'
    //    Glide
    implementation 'com.github.bumptech.glide:glide:4.5.0'
    //DateTimePicker
    implementation 'com.wdullaer:materialdatetimepicker:3.4.0'

    implementation 'org.ocpsoft.prettytime:prettytime:4.0.1.Final'


    implementation 'com.github.kittinunf.fuel:fuel-android:1.12.0'


    implementation 'com.seatgeek:placesautocomplete:0.3-SNAPSHOT'



    implementation project(path: ':regservice')
}

由于

，仍然 gradle 构建失败

错误：任务 ':app:transformDexArchiveWithExternalLibsDexMergerForDebug' 执行失败。 java.lang.RuntimeException: com.android.builder.dexing.DexArchiveMergerException: 无法合并 dex

有人可以找出原因吗？ 我已经解决了这个问题 2 天，但我仍然没有解决方案

Answer 1

创建应用程序类，

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

使用“MyApplication”而不是 android.support.multidex.MultiDexApplication

<application
android:name=".MyApplication"
 />
