DaoObject上的GreenDao NoClassDefFoundError

Question

我正在开发一个最初由其他人创建的Android应用程序。这个应用程序使用GreenDao 2.0.0来存储来自API的对象。在一些设备（如Nexus 5）上一切正常，但由于某些原因，它不适用于我的Android 4.2和4.4设备。代码编译，但是当我想启动我的应用程序它崩溃，我得到以下错误：

11-04 16：26：35.951 6614-6614/com.myeggbox E/AndroidRuntime：致命例外：主 11 - 04 16：26：35.951 6614-6614/com.myeggbox E/AndroidRuntime：进程：com.myeggbox，PID：6614 ** 11-04 16：26：35.951 6614-6614/com.myeggbox E/AndroidRuntime：java。 lang.NoClassDefFoundError：com.myeggbox.api.data.entity.AddressDao

我之前从未使用过GreenDao，所以我迷路了，如果有人有任何想法......在我的build.gradle中，targetSdk是22，minSdkVersion是16. 这是我的EntityGenerator.java：

public static void main(String[] args) throws Exception { 
    Schema schema = new Schema(4, "com.myeggbox.api.data.entity"); 
    schema.enableKeepSectionsByDefault(); 

    //on init les Entity puis on les maps 
    createEntities(schema); 
    mapEntities(); 
    addRelationShip(); 

    new DaoGenerator().generateAll(schema, "../app/src/main/java/"); 
} 

/*

private static void createEntities(final Schema schema) { 
    address = schema.addEntity("Address"); 
    brand = schema.addEntity("Brand");

这不是Android类，它不应该作为Android的一部分运行。

1. 你应该编译这个类作为一个通常的Java文件 （如$ javac的EntityGenerator.java）
2. 然后运行类$ java的EntityGenerator，读完后 检查../app/src/main/java /目录下，你应该有Dao生成的文件来访问你的数据库。
