android - MultiDex 问题 - 任务 ':app:dexDebug' 执行失败

Question

我在为 Google Calendar API 添加一行到 build.gradle 时遇到问题。这是错误:

UNEXPECTED TOP-LEVEL EXCEPTION:
com.android.dex.DexIndexOverflowException: method ID not in [0, 0xffff]:65536

我尝试了很多选项，但没有任何效果。当我将 "multiDex true" 添加到 defaultConfig 时，appcompat 库没有连接到我的项目，应用程序崩溃并显示 java.lang.NoClassDefFoundError: android.support .v7.appcompat.R$layout.

这是我的 build.gradle:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 21
    buildToolsVersion "21.1.2"

defaultConfig {
    applicationId "ua.appp.appp"
    minSdkVersion 14
    targetSdkVersion 21
    versionCode 15
    versionName "2.1.0"
}
buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
   }
 }

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:appcompat-v7:22.0.0'

    compile 'com.google.android.gms:play-services:6.5.87'
    compile 'com.google.apis:google-api-services-calendar:v3-rev119-1.19.1'
    compile 'com.google.api-client:google-api-client:1.19.1'
    compile 'com.google.api-client:google-api-client-android:1.19.1'
    compile 'com.google.api-client:google-api-client-gson:1.19.1'

    compile 'com.github.navasmdc:MaterialDesign:1.+@aar'
    compile 'com.afollestad:material-dialogs:0.6.5.2'
    compile 'com.nhaarman.listviewanimations:lib-core:3.1.0@aar'
    compile 'com.nhaarman.listviewanimations:lib-manipulation:3.1.0@aar'
    compile 'com.nhaarman.listviewanimations:lib-core-slh:3.1.0@aar'
}

PS:一些有趣的事实:当我将所有这些库添加到测试项目时，代码编译并正常运行，没有错误。

当您添加 multidex:true 时，不要忘记在您的项目中创建一个 Application 类，该类扩展自 MultiDexApplication 或会发生很多不好的事情

public class YourApplication extends MultiDexApplication {
    ..........
}

也不要忘记这一点(版本可能会随时间变化，如果您阅读本文，请确保您使用的是最新版本)

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