Android :: Getting Preferences In AppWidget Provider
Apr 30, 2010
I seem to be having trouble reading preferences from my AppWidgetProvider class. My code works in an Activity, but it does not in an AppWidgetProvider. Here is the code I am using to read back a boolean:
SharedPreferences settings = getSharedPreferences(PREFS_NAME, 0);
boolean autoreplyon = settings.getBoolean("autoreplyon", false);
However, I get the "The method getSharedPreferences(String, int) is undefined for the type widget" error (widget is the name of my AppWidgetProvider class).

Shared Preferences are as such used to keep the data static and available.Is there a chance that i can use this ahred preference values over a content uri and make accessible to all ?

I am using a PreferenceActivity to let the user set some values. I am feeding it the xml file with the defined preferences.
I have set all the android:defaultValue="" for them.
When I start my application, I need the preferences, or if they are not set yet manually, I want the default values:
CODE:.................
However, when android:defaultValue="true" I still get false. So, it looks like the defaultValues set in the XML are not used anywhere but when initializing the preferences-screen.
I don't want to hardcode the default values in the getBoolean() method. So, is there a way get the default-values with only defining these in 1 place?

My application is used on multiple platforms so it saves it preferences to a file (rather than to the standard Android SharedPreferences).
Is there any easy of reusing the PreferenceActivity to save preferences to a file or is it a case of creating a whole new activity to do the job? If the latter is the case is there a layout I can use that will make the activity look like the normal preferences screen? PreferenceActivity uses com.android.internal.R.layout.preference_list_content but this doesn't appear to be available to apps for reuse.

I am having a hard time understanding content providers. In the notepad example and others, the content provider never even declares its CONTENT_URI anywhere inside itself, yet the docs say to publicly declare this. It's declared in a different class. So when an activity queries a content provider with a CONTENT_URI, how does Android know which one I want. I see no link between a content provider and its CONTENT_URI declared in another class.
I also don't how to think about intents and content providers. I know that you don't call an intent on a content provider. But an activity queries a content provider without an intent, and an activity has a mimetype attribute in the manifest that would seem to tie it to a content provider.

My android application has two kinds of preferences:
1) I have user preferences defined in res/xml/preferences.xml so that users can manage their preferences with a PreferenceActivity.
2) I'd like to define another file for global configuration preferences of my app.
What is the best way to manage my app config preferences? Should I create another XML file with config values or should I specify those config values in strings.xml? What is the best practice for managing config preferences?

I am attempting to add a simple preferences file in a new Android project (New -> Android XML File), but it doesn't appear to be working correctly.
There is no root element to choose from when I select the Preference type layout. If I press Finish, it doesn't do anything. See screenshot below.

I am trying to debug a problem where my widget becomes invalid and a new one fills in.This only happens once at the beginning of time and then it remains the second widget forever.So, I want to put code in to narrow down the point in time when it happens.Then I would get a list of all the enabled IDs and see if I am in the list. I cannot find a method, member, attribute, etc. that would give me my id?

I am attempting to query a database and update information in the appwidget screen based on changes to the database done while in an activity so that when the user exits, the changes are reflected in the widget on the screen.The appwidget is being updated with a broadcast from OnPause() and OnStop() in my primary Activity.Relevant pieces of the code are below.The Toast shows me that the data is correctly being pulled when OnUpdate() is called.But the widget refused to change

Just wonder what limitations there are for UI elements in AppWidgets? I tried a ListView and was met with an error. I saw the other post that EditText isn't available.Just wondering if there was a full list somewhere?

I have a strange problem, on a few devices. I have developed an AppWidget, and it uses a database to store the configuration for each instance of the widget. The widget id is the key in the database.Everything works on most devices, but I got a bug report a couple of days ago. A user said that the widget never worked after reboot. The user who was very helpful sent me a log from his phone, and I could then see that the widget got a new id each time he did a reboot.

Is it possible to launch an app widget from another application.
For example, I have a button in an application. When I click on that button, an appwidget must be launched.

I am trying to update an AppWidget manually when a user setting changes on the device.I can tell that my AppWidget onUpdate method is being called as a result since I log some debug strings to logcat in the code. However the AppWidget itself doesn't change on the screen.Here comes the interesting part: if I rotate my device and force a refresh of the home screen (from PORTRAIT to LANDSCAPE or vice-versa) then finally my AppWidget gets updated. However rotating the device does not trigger the onUpdate method to be called, so the AppWidget must be using the RemoteViews provided in the earlier update. Can somebody explain me what to do to force the home screen redraw of my AppWidget when it processes an update?

I wrote a widget that has been working fine for most folks. However, I started getting bug reports about how the widget would be blank on reboot (not receive an update?), and it seemed that the Sprint Hero continually came up. I thought I was crazy but I'm finding that other people are having the same problems:Searching Google for "sprint hero appwidget problems" yields:"Added warning about the problem on the Sprint Hero device: On the Sprint Hero (HTC ROM v1.29.xxx) the AppWidget API is broken in such a way that it won't."I e-mailed the author in hopes of getting an answer, but I haven't received any response. Does anybody with a Sprint Hero know what the problem is?

Using Appwidgets, If we use TextView in layout provider xml then, we are able to set the text in Provider.java using remoteViews.setTextViewText() method.
Similarly, if I use AnalogClock as AppWidget in xml then, is there any method available to change the android:dial value using RemoteViews or AnalogClock api's in Provider.java ?
For Ex- I need to load two dial png's based on AM or PM.

I'm developing a Android AppWidget for my application. For updating my appwidget I need to download data from network. But when I try to do that in onUpdate method, my appWidget is killed by Android system. I learnt that time consuming operations can't be done in receivers so I launched a service from onUpdate method and launched a thread from that. But still the problem persists.
Can anyone please let me know how to do network operations in Appwidget?

I've been looking at the new 1.5_pre SDK today, and the new AppWidget API in particular. I was hoping to write a widget for posting to Twitter as part of my nanoTweeter app. The interface I had in mind would look very similar to the Google Search widget, with an EditText and a submit Button, but as far as I can see there's no way to get at user input in a RemoteViews. Is that right, or am I overlooking something?

Is it possible to receive SMS message on appWidget?
I saw android sample source(API Demos).
In API Demos, ExampleAppWidgetProvider class extends AppWidgetProvider, not Activity.
So, I guess it is impossible to regist SMS Receiver like this code...
My goal is to receive SMS message on my custom appWidget.

The documentation hints that: "...the lock screen could also contain widgets, and it would have a different way of adding, removing and otherwise managing widgets." [1]
Now that I have 1.5, I can see the lock screen changed to show the same background as the home screen. Is there a way to put AppWidgets on the lock screen in 1.5?

I'm playing around with the new AppWidget API, I get the impression from the docs that I don't need an android:configuration attribute in my AppWidgetProviderInfo xml resource. Curiously though, when I try to add my AppWidget to the home screen, I just get a black textview that reads "Problem loading widget".

I would need a fast updating (minimum 5 frames/second) appwidget which can be on the desktop all the time (like the cpu usage or other things mostly measurement gauges).The appwidget is not a "must" but I've found it easy to configure for any customer so the management is easy and I need those gauges to be shown like an appwidget on the desktop.The only problem is the update speed - I've seen that appwidget is not really thought for my needs. In my case it's not about phones, the small unit will always have power supply so draining the battery is not an issue. I could tweak the 30 minute update time but it doesn't helps too much - the appwidget framework is simply too slow with all that serialization and would eat too much CPU. What other solutions can be used? I've seen that a system service (LoadAverageService for example) would do the job but that one is not really configurable, has to be compiled into Android so I kinda don't like it. The same is valid with custom app screens or any other solution which needs an custom Android build. So this is a last solution if nothing else works.
A good solution could be if the Appwidget framework would accept other views than the enlisted ones (AnalogClock, Button, Imageview, etc.) and the update would be done internally in the widget, not through the appwidget serialization chanels.

I'm trying to create an appwidget with a customizable background. I use a NinePatchDrawable and I would like to change it's color (using the setColorFilter method). This is no problem in an Activity, but it does dot seem possible with the RemoteView object used for appwidgets.Is there some way to get an ImageView in an appwidget to be updated with a new Drawable, not a Bitmap?Or if not, perhaps it's possible to get the actual size of the appwidget and convert / save the colored NinePatchDrawable to a Bitmap and then update the ImageView with that?I already searched quite a bit for a solution, but haven't found anything so far. I hope it's not impossible.
