如何在Activeandroid中禁用模型扫描

我想使用AA_MODEL标记在 AndroidManifest.xml文件中定义我的模型类并禁用自动搜索.因为当前我在应用程序启动时遇到错误类似于：

Couldn't create class.
    java.lang.classNotFoundException: android.support.v4.print.PrintHelperKitkat$1

怎么做得好？你能告诉我一个定义明确的AA_MODEL标签的例子吗？

解决方法

您可以在Application对象中定义模型.此禁用模型自动搜索.

public class ShantApplication extends Application {

@Override
public void onCreate() {
    super.onCreate();

    initializeDB();
}

protected void initializeDB() {
    Configuration.Builder configurationBuilder = new Configuration.Builder(this);
    configurationBuilder.addModelClasses(Test.class);
    configurationBuilder.addModelClasses(ShoppingList.class);
    configurationBuilder.addModelClasses(ShoppingListItem.class);
    configurationBuilder.addModelClasses(ArticleInfoModel.class);

    ActiveAndroid.initialize(configurationBuilder.create());
}

}
