摘录解决步骤如下：
1、在build.gradle中，设置multiDexEnabled：

android {
   defaultConfig {
      multiDexEnabled true
   }
}

2、引入multidex库

dependencies {
   compile 'com.android.support:multidex:1.0.0'
}

3、将你的Aplication继承自MultiDexApplication，或是在manifest中指定application的属性

android:name="android.support.multidex.MultiDexApplication"

如果你的Application继承自别的类，那就需要重写attachBaseContext

protected void attachBaseContext(Context base) {
    super.attachBaseContext(base);
    MultiDex.install(this);
}
