Android :: AppWidget Layout Resetting After Device Restart
Aug 15, 2010
I have a simple appWidget that displays an image. The image is selected in the configuration activity and the widget is updated via the remove view. This is done on a button push executing the code below:
Intent intent = new Intent(context, KidDialog.class);
intent.setData(selectedImage);
PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, intent, 0);
widgetView.setOnClickPendingIntent(R.id.centerBrd, pendingIntent);
widgetView.setImageViewUri(R.id.widImg, selectedImage);
appWidgetManager.updateAppWidget(appWidgetId, widgetView);
Intent resultValue = new Intent();
resultValue.putExtra(AppWidgetManager.EXTRA_APPWIDGET_ID, appWidgetId);
setResult(RESULT_OK, resultValue);
finish();`
As you can see, it is also seeing an PendingIntent for the onClickListener of the image. I don't think that is relevant here. Anyway, this work great. The widget does exactly what I want it to. Until I restart the device. When I restart the widget loads with the default view from the xml in the apk. It does not keep the image update from the initial configuration. My questions is how do I get the widget to load back up after a restart with the updated view set during the configuration activity? I will also need to reset the onClick Pendingintent, but I will save that for later.

My Android app Transdroid offers several home screen widgets. Every AppWidget has 2 'buttons' (ImageButton), one starts the app and one starts some activity that refreshes the AppWidget content. Pretty simple. Here is a screenshot.The problem is: the widget's onUpdate is not called after the Home process is restarted, and hence the PendingIntents used to attach functionality to the buttons is lost.
More precise: no onReceive and thus no onUpdate is called when the android.process.acore Home process is restarted. In turn, no Intent is attached..Anyone experienced the same problem and knows how to circumvent this problem?

I rooted my Droid today for the first time.The first time it turned on after installing the new ROM it kept resetting after the MOTO icon would come up.It was doing this for quite a while and I kept removing the battery and powering off and on and then finally it started up.Phone was running great after that and was OCing at 800.Used it for about 5 hours like this.Then I went to set up OC profiles and hit refresh and now the phone keeps resetting at Moto icon again and hasn't turned back on.Is there something I can do to fix this?

Every time I reboot my phone it keeps changing my background back to the same stupid image below. I think I'm probably going to go insane if I see this stupid grass anymore. The picture isn't even on my phone (anywhere I can see, obviously.) I don't know what to do. I've flashed several Roms, done several factory resets, changed it to a million different images/live wallpapers.

I'm writing an app-widget that displays some numbers, each with label in front of it.
The layout looks like this:
.-----------------------------.
| Label1 | AAAAAAAAAAA |
| LongerLabelLabel2 | BBBBBBB |
| LongLabel3 | CCCCCCCCCC |
'-----------------------------'
There is one outer (vertical) LinearLayout, and each row is a horizontal LinearLayout with two TextViews.
The problem is that the numbers get ellipsized if the width of the label and the number is too wide for the widget. I want the labels to get ellipsized.
The above situation for instance, would end up like this:
.-----------------------------.
| Label1 | AAAAAAAAAAA |
| LongerLabelLabel2 | BBBB... |
| LongLabel3 | CCCCCCCCCC |
'-----------------------------'
instead of the desired
.---------------------------.
| Label1 | AAAAAAAAAAA |
| LongerLabelL... | BBBBBBB |
| LongLabel3 | CCCCCCCCCC |
'---------------------------'
I can't for my life figure out how to solve this. Any help is appreciated.
My current layout is the following:

I am testing an android device with eclair using the 2.1 CTS version. When CTS completes a set of tests and restarts the device a "device disconnected" messages appears on the CTS console. However after the device completes the restart to the android home screen CTS does not detect that the device is back online. I have to physically disconnect the USB cable and re-connect it. Do you think this is a device side issue or a USB driver issue on the Ubuntu machine (intrepid) where I am running the CTS?

I am developing a ToDo reminder type of app for android. on creation of a new reminder an alarm and vibrator scheduler is created with a toast. This works on intents and broadcasts and is pretty straight forward stuff with putextras using the reminder id from the db. My problem is, if some one restart the phone, i guess all the scheduled alarm and vibrator tasks for the reminder will be killed. Once the phone restart again how to recreate the scheduler tasks.

You know that layout editor in the Android ADT plugin that lets you design the layout for ADP1, ADP2 and Nexus One, has anyone created other device configurations? It requires device information such as the x-dpi and y-dpi, which can be difficult to find out. I'm just wondering if anybody has added more device configurations they're willing to share? Perhaps together we could compile a huge devices.xml containing many of the devices out there. I'm fully aware the layout editor has many faults and cannot be relied upon but it is sometimes useful to rapidly preview how the layout might look on a wide variety of devices without switching between emulators.

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?

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).

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?
