Question

我在AndroidManifest.xml上配置了ActiveAndroid，如下所述：

<application
        android:name="com.xxx.xxxx.XXXApplication"
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        <meta-data
            android:name="AA_DB_NAME"
            android:value="MyDB.db" />
        <meta-data
            android:name="AA_DB_VERSION"

            android:value="2" />
...
</application>

申请类：

public class XXXApplication extends Application {

    @Override
    public void onCreate() {
        super.onCreate();
        ActiveAndroid.initialize(this);
    }
}

模式类是：

@Table(name = "Routes")
public class Route extends Model {
...

   public static List<Routes> all(){
      return new Select().from(Route.class).execute();
   }

}

Ps：我按照文档说明： https://github.com/pardom/ActiveAndroid/wiki/Getting-started

当调用Routes.all（）时出现此错误：

尝试在未准备的类中执行代码'Lbr / com / xxx / xxx / xxxx / models / Route;'

完整筹码是：

Answer 1

这已经很晚了，但可以帮助那些面临同样问题的人。此问题仅发生在调试模式中，以解决它：

删除所有涉及无准备课程的监听表达式（在“调试视图”中）。
如果您不在代码中使用该类，只需删除它（这也解决了第一点）。希望它有所帮助。

Answer 2

你还记得为Route写一个标准的构造函数吗？ E. g。

public Route(){
    super();
}

如果您有自己的Application类，则必须从com.activeandroid.app.Application：

派生

public class Application extends com.activeandroid.app.Application {
    …
}

如果这没有帮助，请发布路线签名。

ActiveAndroid似乎没有初始化
