App Widget not displaying in ICS app drawer

由 删除回忆录丶 提交于 2019-12-01 19:41:14
问题 Has anyone experienced their app widget not being listed in the ICS app drawer? Originally I started this app for FroYo and below, which supports the app widget just fine. Along came Gingerbread and Honeycomb, those work too. The widget appears in the list in the emulator if I open up the "Widget Preview" app, however when you just open the drawer it isn't listed with the others. It does appear on Honeycomb. I don't (and others haven't also) see it on my Galaxy Nexus anywhere either. I've

I've been working on a widget and making some advances (I hope) but still can't get it to do what I want. I have a configurator activity which works ok. When it closes I call the updateAppWidget method in the WordWidget class and the widget updates the random number. What I can't do it get the random number to change because of onClick. According to the log I do enter the onReceive() method, but thats about it. In the log I'm printing the widget ID. I noticed that when run from the configurator activity it's printing appWidgetId=33, but when I press the widget it prints appWidgetId=24. This is

I have widget that display data from content provider. I want to know when data in content provider changes. As far as I know way to do it is context.getContentResolver().registerContentObserver But AppWidgetProvider.onEnabled method is not called when I add first instance of the widget. That's why I can't make registerContentObserver . The same with onDisabled. How to solve this problem? Thanks You need to add android.appwidget.action.APPWIDGET_ENABLED as another action: <intent-filter> <action android:name="android.appwidget.action.APPWIDGET_UPDATE" /> <action android:name="android.appwidget

How to show an actitivity only when an app widget is first created?

My app widget needs to be configured when it first added to the home screen. I want to open a configuration view right after the user adds the widget. AppWidgetProvider has no onCreated event, so I'm showing the confugration activity on the onUpdate event, and store a boolean value in SharedConfiguration that marks that the configuration has already been shown. Is there an easier way? In the AppWidgetProvider XML file there is an attribute called android:configure You can use this to point to an Activity to launch when the app is dropped onto the home screen. ex: <?xml version="1.0" encoding=

4x4 appwidgets are detected as 3x3 on tablets

I create an 4x4 appwidget with minWidth and minHeight set to "250dp" as it is suggested in App Widget Design Guidelines: http://developer.android.com/guide/practices/ui_guidelines/widget_design.html It is ok on every phones and phone-sized emulator I have tried but if I test it on a tablet (Xoom or Nexus 7) or on an emulator (resolution: 1280x752 with dpi 160) then the launcher detects it as 3x3 widget. What am I doing wrong? Thanks, Tamas Try grid size = (74*n) - 2 for older api level. This value come from old document. 来源： https://stackoverflow.com/questions/11868015/4x4-appwidgets-are
