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。在某些设备(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。代码可以编译,但是当我想启动我的应用程序时它会崩溃并且我收到以下错误:

11-04 16:26:35.951 6614-6614/com.myeggbox E/AndroidRuntime: 致命异常: main 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

我以前从未使用过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");

这不是一个 Android 类,它不应该作为 Android 的一部分运行。

  1. 您应该将此类编译为普通的 java 文件(如 $javac EntityGenerator.java)
  2. 然后运行 ​​$java EntityGenerator 类,完成检查 ../app/src/main/java/ 目录后,您应该有 Dao 生成的文件来访问您的数据库。
