VM有multidex支持，禁用multidex支持库。问题

Question

android {
    compileSdkVersion 25
    buildToolsVersion '25.0.0'

defaultConfig {
    applicationId "com.rocketjourney"
    minSdkVersion 21
    targetSdkVersion 24
    versionCode 68
    versionName "4.41"
    multiDexEnabled true
    vectorDrawables.useSupportLibrary = true
    testInstrumentationRunner "com.rocketjourney.helpers.CustomTestRunner"
}

configurations.all {
    resolutionStrategy.force 'com.google.code.findbugs:jsr305:1.3.9'
    resolutionStrategy.force 'com.squareup.okio:okio:1.13.0'
    resolutionStrategy.force 'com.squareup.okhttp3:okhttp:3.8.0'
}

dexOptions {
    javaMaxHeapSize "4g"
    jumboMode = true
}`

repositories {
    mavenCentral()
    maven { url 'http://oss.jfrog.org/artifactory/oss-snapshot-local' }
    maven { url "https://jitpack.io" }
    flatDir { dirs 'libs' }
    flatDir { dirs '../aars' }
    maven { url 'https://maven.fabric.io/public' }
}

dependencies {
    compile('com.crashlytics.sdk.android:crashlytics:2.7.1@aar') { transitive = true; }
    etc...
}`

我的舱单是这样的：

<application
    android:name="com.rocketjourney.RJApplication"
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"

在我的rjapplication.class中有以下代码：

public class RJApplication extends Application {

  @Override
  protected void attachBaseContext(Context base) {
    super.attachBaseContext(base);
  }

但我现在的错误是：

Answer 1

如果minSDKversion是21，则不需要添加multidex支持。

从文档中可以看到：

支持Android 5.0及更高版本的Multidex
