我已经安装了Google Play服务＆＃39;修订版30 还添加了应用程序ID 同时覆盖attachBaseContext，MultiDex.install（this）; 但没有任何作用

Answer 1

有同样的问题，我已完成如下

使用最新的Google Play服务但无效。对我来说，这个程序正在起作用：1。更新了我的Application类：

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

更新了build.gradle文件：

  defaultConfig { ...

  multiDexEnabled true

  }

包含依赖项：

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

问题现已修复

android 4.1.2的java.lang.ClassNotFoundException
