android - 如何在不破坏 Robolectric 的情况下添加 WidgetProvider

Question

我有一个使用 Robolectric 1.1 和 Roboguice 2 的测试套件。它运行良好。

我将 AppWidget 添加到应用程序 list 中，如下所示:

<receiver android:name="NearestOpenCragWidgetProvider" android:exported="false">
                <intent-filter>
                    <action android:name="android.appwidget.action.APPWIDGET_UPDATE" />
                </intent-filter>
                <meta-data android:name="android.appwidget.provider"
                       android:resource="@xml/nearest_open_crag_widget_info" />
            </receiver>

我创建了一个类

public class NearestOpenCragWidgetProvider extends AppWidgetProvider {
     public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) {
            final int N = appWidgetIds.length;

            // Perform this loop procedure for each App Widget that belongs to this provider
            for (int i=0; i<N; i++) {
                int appWidgetId = appWidgetIds[i];

                //get the layout
                RemoteViews remoteViews = new RemoteViews(context.getPackageName(),
                        R.layout.nearest_open_crag_widget);

                // Tell the AppWidgetManager to perform an update on the current app widget
                appWidgetManager.updateAppWidget(appWidgetId, remoteViews);
            }
        }
}

和 res/xml 中的 AppWidgetProviderInfo xml

<?xml version="1.0" encoding="utf-8"?>
<appwidget-provider xmlns:android="http://schemas.android.com/apk/res/android" >
    android:minWidth="294dp"
    android:minHeight="72dp"
    android:updatePeriodMillis="86400000"
    android:initialLayout="@layout/nearest_open_crag_widget"
    android:resizeMode="none">
</appwidget-provider>

并且还添加了布局 nearest_open_crag_widget

现在，当我运行我的测试时，它们会立即失败

应用程序以 2.3 为目标，如果我在 Android Manifest 中注释掉 Widget 声明，测试将再次开始运行。

我显然遇到了一些问题，想知道主脑是否能发现它。

原来问题应该是“如何添加小部件提供者而不是白痴”。如果我在 android list 中使用 Provider 的完全限定名称，那么一切都很好

<receiver android:name="uk.co.some.package.NearestOpenCragWidgetProvider" android:exported="false">
     <blah />
</receiver>
