Greendao 和 NoClassDefFoundError

Question

在使用greendao的过程中，初始化的时候，报错：

java.lang.NoClassDefFoundError: org.greenrobot.greendao.query.WhereCollector

编译过程中并没有出现这个异常，实际错误代码在运行时直接崩溃如下：

AndroidRuntime: FATAL EXCEPTION: main
 Process: com.luckytry.hybrid.mainapplication, PID: 4274

Answer 1

试试这个：

-添加这个依赖compile 'com.android.support:multidex:1.0.1'

-在您的 build.gradle 应用配置中添加 multiDexEnabled = true。

-将您的扩展应用程序 "MyAplication.APPAplication" 更改为 MultiDexApplication。
