Depending on what I do in my application, I might want to force an update on my widget. I've have had a poke around and can't seem to find any API for doing a manual update. At the moment, I have a function that sends a broadcast and my onReceive does this:
CODE:...............
Is there a proper way to do this, which sents the int array to the correct values? Or do I have to do it like this instead?

I can create a static widget without thinking, I can even create a widget like the analogue clock widget that will update itself, however, I can not for the life of me figure out how to create a widget that reacts to when a user clicks on it. Here is the best code sample that the developer documentation gives to what a widget activity should contain (the only other hint being the API demos, which only creates a static widget):
public class ExampleAppWidgetProvider extends AppWidgetProvider {
public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) {
final int N = appWidgetIds.length;
// Perform this loop procedure for each App Widget that belongs to this provider
for (int i=0; i<N; i++) {
int appWidgetId = appWidgetIds[i];
// Create an Intent to launch ExampleActivity
Intent intent = new Intent(context, ExampleActivity.class);
PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, intent, 0);
// Get the layout for the App Widget and attach an on-click listener to the button
RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.appwidget_provider_layout);
views.setOnClickPendingIntent(R.id.button, pendingIntent);................
Can you please tell me where is the android code which picks the different drawable will be used as background when it has focus? Where is the android code which finds out which drawable it should used for the widget's background?

I am starting with Android programming with the help of Unlocking Android / Manning which came from Santa and is a pretty good book. After running a few little tests and examples, I'm moving towards developing the concepts for my own application.I want my App to execute as a Home Widget and I'm using this example as my model to get started.While I am able to load and run in the Android ADB emulator the code example in the example's Wiktionoary which is a normal Android App. I am not able to run, but only load into the emulator the Widget version of that code named SimpleWiktionary.Am I am able to debug Android Home Widgets with the emulator? If so, what am I missing on starting/activating the Widget or having it show up in the Apps window?

I am currently learning about widgets in Android. I want to create a WIFI widget that will display the SSID, the RSSI (Signal) level. But I also want to be able to send it data from a service I am running that calculates the Quality of Sound over wifi. Here is what I have after some reading and a quick tutorial: public class WlanWidget extends AppWidget Provider {RemoteViews remoteViews; AppWidgetManager appWidgetManager; Component Name thisWidget; WifiManager wifiManager; public void onUpdate(Context context, AppWidgetManager appWidget Manager, int[] appWidgetIds) { timer timer = new Timer(); timer.schedule AtFixed Rate(new WlanTimer(context, appWidgetManager), 1, 10000); The above seems to work ok, it updates the SSID on the widget every 10 seconds. However what is the most efficent way to get the information from my service that will be already running to update periodically on my widget? Also is there a better approach to updating the the widget rather than using a timer and timertask?

I have 2 buttons and i need to change one button text when i press the other one, how can i do this?
The first time i open the widget it calls the onUpdate method, but it never calls it again. I need to update the widget every 2 seconds and i have this line in the xml.
android:updatePeriodMillis="2000"
Do i need a service or should it works just with the updatePeriodMillis tag?

View 1 Replies View RelatedI have been looking for a way to update a widget asynchronously, for example, when the phone receives a text message. I have a broadcast receiver set up with code that runs upon receiving a message. I also have an AppWidgetProvider that is set up and running. It seems like the *only* way a widget can be updated is upon its interval, or when the user interacts with it. Is there any way to update a widget upon a system event?
View 6 Replies View RelatedI have a widget, its setup so that when I click on it, it opens some settings in an activity.

This configures some settings for the application. What I want to achieve is to have the widget update its view to reflect the changed settings when the Activity I launch closes. Using the update interval or any other type of polling isn't appropriate for this.

View 2 Replies View RelatedI'm going to create widget which needs to update its content every minute (it shows time-related data).
However, there is no need to update widget if it is currently invisible, which means:
screen is turned off
another app is running
widget is placed on another (invisible) home screen tab
What is the best way to update only visible widget every minute - without waking up device nor doing unnecessary computations? After widget becomes visible, small lag before update is acceptable.
I respond to a button press on my appwidget in the onreceive method. When the button I pressed, I want to force the widget to call the onupdate method.
View 2 Replies View RelatedI'm just starting with android development and have written an application to show details about the battery status.
Now I wanted to put the whole thing into an widget - and here's the question:
Do I really need a update service in the background to listen for ACTION_BATTERY_CHANGED intents? My first thought was to put just a <action android:name="android.intent.action.ACTION_BATTERY_CHANGED" /> line into the <intet-filter> tag of the widget in the AndroidManifest.xml - but obviously it's not that simple.
If the UpdateService is the right way I'll do so - but I just wanted to make sure what the proper solution is.
I wrote one widget that updates per 5-seconds and I found that if it's run for a period of time, com.android.acore will occupy almost 100% cpu. Could somebody give me suggestions or help?
View 9 Replies View RelatedI hope it is the right android group for this question. I have a widget that is essentially an image button that toggles display and speaker modes on a custom Android 2.1 platform. It also displays different images to indicate what mode is currently selected. We are adding a hardware button that can also change the same display modes externally. I will have a driver that translates button presses to some events (maybe emulate a key press through input events or something else). If the user changes the mode by pressing hardware button, the widget will not know about that and will display wrong image. Is there a way to synchronize the widget state with the current mode without constantly polling the driver from the widget code? Widget can start a background service that would poll my driver every second or so and update the picture according to the mode reported by the driver. It does not look like a good solution to me. Can widgets receive any events besides clicks? Can widget detect when it becomes visible ? It looks like "remoteViews" cannot register any event listeners other than OnClickListener
