无法将小部件添加到主屏幕-未安装应用 [英] Can't add the widget to the home screen - App isn't installed

问题描述

我正在尝试创建我的第一个小部件.
我通过Eclipse运行该应用程序，并且启动正常.但是，当我尝试将小部件菜单中的小部件添加到主屏幕时，我看到了一个吐司:

I'm trying to create my first widget.
I run the app through eclipse, and it launches fine. But when I try to add the widget from the widgets menu to the home screen I get a toast that says:

未安装应用

当我查看logcat时，会看到此错误:

When I look at the logcat I see this error:

05-15 18:35:10.533:E/Launcher(851):错误:\ widget配置活动未返回appWidgetId(EXTRA_APPWIDGET_ID).

05-15 18:35:10.533: E/Launcher(851): Error: appWidgetId (EXTRA_APPWIDGET_ID) was not returned from the \widget configuration activity.

我根本没有配置活动，据我从开发人员的站点了解，这不是必须的.

I don't have a configuration activity at all, and as far as I understood from the developer's site, it's not a must.

推荐答案

您需要在结果意图中放入 EXTRA_APPWIDGET_ID :

You need to put EXTRA_APPWIDGET_ID in result intent like this:

setResult(RESULT_OK, new Intent().putExtra(AppWidgetManager.EXTRA_APPWIDGET_ID, mWidgetId));
