GreenDao在DaoObject上出现NoClassDefFoundError

Question

我正在开发一个最初由其他人创建的Android应用程序。此应用程序使用GreenDao 2.0.0存储API中的对象。在某些设备上一切正常（如Nexus 5），但由于某些原因，它在我的Android 4.2和4.4设备上不起作用。代码编译了，但当我想启动我的应用程序时，它崩溃了，我得到了以下错误：

11-04 16:26:35.951 6614-6614/com.myeggbox E/AndroidRuntime：致命异常：main11-04 16:26:35.951 6614-6614/com.myeggbox E/AndroidRuntime：进程：com.myeghbox，PID:6614**11-04 16:26:35.951 6614-6614/com.myeggbox E/AndroidRuntime:java.lang.NoClassDefFoundError:com.myegsbox.api.data.entity.AddressDao

我以前从来没有用过绿刀，所以我迷路了，如果有人知道的话。。。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/");
}

Answer 1

这不是一个Android类，它不应该作为Android的一部分运行。

1. 您应该将这个类编译为一个普通的java文件（类似$javac EntityGenerator.java）
2. 然后运行类$java EntityGenerator，完成后检查/app/src/main/java/目录，您应该有Dao生成的文件来访问您的数据库
