公共void onUpdate（上下文上下文，AppWidgetManager AppWidgetManager，int[]AppWidgetId）{
final int N=appWidgetIds.length；
//对属于此提供商的每个应用程序小部件执行此循环过程
对于（int i=0；i这是一个关于您在gulp_widget_info.xml
中为android:minHeight
和android:minWidth
设置的值的问题
尝试设置较小的值，小部件应出现在启动器的小部件列表中：
<appwidget-provider xmlns:android="http://schemas.android.com/apk/res/android"
    android:initialLayout="@layout/layout_widget"
    android:minHeight="40dip"
    android:minWidth="40dip"
    android:updatePeriodMillis="86400000"
    android:widgetCategory="home_screen"
    android:resizeMode="none" />

根据链接，活动必须在AppWidgetProviderInfo XML文件中声明，带有android:configure属性，但您缺少此属性。
尝试重新启动电话正如我在原始帖子中提到的，我已经尝试过了。尝试为android:name=“GulpWidgetProvider”使用完全限定的类名在接收方xml上？@CSmith您是否建议在GulpWidgetProvider前面加上句点？例如：android:name=“.GulpWidgetProvider”
。我刚刚完成了这项工作，但小部件仍然没有出现在列表中。请输入类的完整路径，例如com.yourcompany.yourapp.gulp.GulpWidgetProvider。这只是一个猜测，因为我就是这样做的。回答很好。谢谢。我发誓我第一次读到它时就奖励了它。Stack刚刚给我发了一封电子邮件提醒我这么做，所以在这里是的！仅当您正在创建配置活动时才可以执行此操作。
