android - 如何在 Activeandroid 中禁用模型扫描

Question

我想使用 AA_MODEL 标签在 AndroidManifest.xml 文件中定义我的模型类并禁用自动搜索。因为目前我在应用程序启动时遇到类似以下错误:

Couldn't create class.
    java.lang.ClassNotFoundException: android.support.v4.print.PrintHelperKitkat$1
            at java.lang.Class.classForName(Native Method)

            at dalvik.system.NativeStart.main(Native Method)

如何正确地做到这一点？你能给我举个定义明确的 AA_MODEL 标签的例子吗？

您可以在 Application 对象中定义模型。这会禁用模型自动搜索。

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());
}
