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".

Say that there is an App Widget that shows a configuration Activity when placed. The configuration page allows adjusting the appearance of the widget.
The user may place multiple instances of this widget on their home screen. What would be the best way to maintain the unique configuration states on each of the widget instances? Or would each widget instance have to adopt the same global state?
In Java ME we can set .jad configuration in description file and we can get this values in midlet by getAppProperti(""); So in Android we can set apk configuration (eclipse) apk configuration. But when I set this! my file default properties change and my projet signal some error. So in activity when can add System.setProeprty("name","values"). My problem I wan to specify the server IP and some code in apk only for this apk file. Each apk can have his code and server IP.

View 3 Replies View RelatedI'm writing a widget with a configuration activity which calls the following method when its OK button is clicked:
CODE:..............
This is almost verbatim from the documentation. widget_id holds the widget ID that was dug up during the activity's onCreate().
When I place an instance of the widget on the home screen, I've verified that I get the expected sequence of events:
onReceive() gets an ACTION_APPWIDGET_ENABLED if it's the first one.
onUpdate() gets called (in which I detect that the widget isn't configured and draw something as a default action).
The configuration activity appears.
When I press OK, the ok() method above gets called.
The method gets all the way through to the finish() and the configuration activity goes away, but there's no call to onUpdate() or onReceive() after this point. (The widget itself has no updatePeriodMillis.) I end up with a widget on the screen that has the results of my default action but never gets updated.
If I set the widget up without a configuration activity, it gets updated when created and everything works as expected (just without the configured bits).
I have a widget with a configuration activity.
Currently the configuration launches when you click on the widget.
I want to add the configuration as an app icon to the launcher.
The problem is that when the configuration launches on click, I get a specific widget id , so each widget instance can have a different configuration.
What will happen if I start the activity from the launcher?
I wont be able to show multiple configurations on the same activity.
I'm having an issue with a config activity for a widget. According to the dev docs, if I specify a configuration activity than the onUpdate method of the AppWidgetProvider doesn't get called until after you request an update once you've completed the configuration activity. For me its happening in reverse, the onUpdate method of the AppWidgetProvider gets called first, followed by the configuration activity. Then the onUpdate method is never called after completion of the config activity even though I request it explicitly. I tried with level 4 and level 7 API, same result. Here is some of the source:

</appwidget-provider>
I can include source of the onUpdate method from the AppWidgetProvider activity and the onCreate method of the configuration activity if necessary, but they are both being called find its just the order they show up on the emulator is wrong.
Is there a way how I can tell the Preference Activity that value should be saved as integer? So far my all values are saved as strings... I can limit input to integers via XML easy:
<EditTextPreference android:key="SomeKey" android:numeric="integer" />
but it is still saved as string and later trying to getInt("SomeKey") on preferences object I always get java.lang.ClassCastException: java.lang.String.
Is there a way that EditTextPreference value would be saved not as string? Or maybe I should use some other type of Preference for numeric input?
I have an app widget.It has 4 buttons, one one of the buttons I want it to show me the current location of the user on the map.when I run the app the following errors occur, looks like it cannot find the MapActivity class, im running it on the GoogleApps 1.5 instead of normal android 1.5 as well.
View 6 Replies View RelatedI 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?

View 8 Replies View RelatedI 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?
View 2 Replies View RelatedI 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?
View 8 Replies View RelatedUsing 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?

However, I get the "The method getSharedPreferences(String, int) is undefined for the type widget" error (widget is the name of my AppWidgetProvider class).
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...

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?

View 2 Replies View RelatedHow can i put appwidget on my view and let it updated itself??now,i can put the remoteviews on my activity,but it seems not update itself, how can i make it update itself?
View 1 Replies View RelatedI 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.
