MultiDex示例：
AndroidStudio中MultiDex配置：
1、grandle配置
apply plugin: 'com.android.application'android { compileSdkVersion 27 defaultConfig { applicationId "com.zq.multidexdemo" minSdkVersion 16 targetSdkVersion 27 versionCode 1 versionName "1.0" testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner" multiDexEnabled true setMultiDexKeepFile file("multidexkeepfile.txt") } buildTypes { release { minifyEnabled false proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' } }}dependencies { implementation fileTree(dir: 'libs', include: ['*.jar']) implementation 'com.android.support:appcompat-v7:27.1.1' implementation 'com.android.support.constraint:constraint-layout:1.1.3' testImplementation 'junit:junit:4.12' androidTestImplementation 'com.android.support.test:runner:1.0.2' androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2' implementation "com.android.support:multidex:1.0.1"}
2、multiDexKeep.txt文件,生成工具 ApkClasses.exe
备注：若出现DexArchiveMergerException，则为multiDexKeep.txt中的类路径、或名称配置有问题
Caused by: java.lang.RuntimeException: com.android.builder.dexing.DexArchiveMergerException: Error while merging dex archives: D:\sci\ADT\workspace\**
Caused by: com.android.tools.r8.CompilationFailedException: Compilation failed to complete
Caused by: com.android.tools.r8.utils.AbortException
3、Application中调用MultiDex
package com.ltsdk.union; import android.app.Application;import android.content.Context;import android.support.multidex.MultiDex; // 自定义 Applicationpublic class LtsdkApplication extends Application { @Override public void onCreate() { super.onCreate(); } @Override protected void attachBaseContext(Context base) { super.attachBaseContext(base); MultiDex.install(this); // 调用MutiDex }}
