Android :: Programmatically Update Widget From Activity?
Aug 11, 2010I know it's possible, but I can't figure out a way to trigger an update of my widget from the main activity. Isn't there some general intent I can broadcast?

Android :: Update A Widget From An Activity?
Sep 22, 2009I 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?

Nov 1, 2010I have a widget, its setup so that when I click on it, it opens some settings in an activity.
CODE:................
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.
I've seen a couple places here and in the android docs this code used:

Android :: Widget - Update From My Activity?

View 3 Replies View RelatedAndroid :: Widget Configuration Activity - Update Request
Sep 18, 2010I'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:
Manifest:
<?xml version="1.0" encoding="utf-8"?> <manifest
xmlns:android="http://schemas.android.com/apk/res/android"
package="com.chris.android.swidget"
android:versionCode="1" android:versionName="1.0">
<application android:icon="@drawable/app_icon" android:label="@string/app_name">
<activity android:name=".SWidgetConfigure">
<intent-filter> <action android:name="android.appwidget.action.APPWIDGET_CONFIGURE" />
</intent-filter> </activity>
<receiver android:name=".SWidgetProvider" android:label="@string/ widget_name">
<meta-data android:name="android.appwidget.provider" android:resource="@xml/swidget_info"/> <intent-filter> <action android:name="android.appwidget.action.APPWIDGET_UPDATE" />
</intent-filter> </receiver>
<service android:name=".service.PUpdateService" />

android:updatePeriodMillis="86400000"
android:initialLayout="@layout/swidget_layout"
android:configure="com.chris.android.swidget.SWidgetConfigure" >
</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.

Android :: Programmatically Animate Between Images In Gallery Widget
Apr 28, 2010I'd like to programmatically move between images in the Gallery widget, with animation.
I can change the currently displaying image using the setSelection(int position) method, however that does not animate. Then there's setSelection(int position, bool animate) but the extra boolean on the end there doesn't appear to do anything.
In the source of Gallery it appears that it can handle DPAD key-presses, so a work-around I thought of was to fake the key-presses. Eg.
dispatchKeyEvent(new KeyEvent(KeyEvent.ACTION_DOWN, KeyEvent.KEYCODE_DPAD_LEFT))
However I can't get this working for some reason. Anyone tried this?
I notice three of the widget's methods I'd love to use moveNext(), movePrevious() and scrollToChild() are all private and unusable.
Does anyone know how I might be able to do this?
Android :: App Widget Configure Activity Opens Main Activity
Jan 10, 2010I hav an app that is like a relational database. There is a main app activity that users manage things with. There is also a widget that will display important info and add data to the database. When the widget is clicked, a configure class displays a way for the user to edit data. When the configure activity is done, the widget is updated and instead of going back to the home screen, the apps main activity is started. I can't find where the main activity is being called from. Wouldn't I have to create an intent and start Activity() to get this behavior? When done updating, I want the home screen and not my app.

PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, intent, 0);
// Get the layout for the App Widget and attach an on-click listener to the button

Android :: Added Contact Not Visible In Contacts App / Programmatically Update Them?
May 6, 2010I'm developping an application in Android 1.6 (and can't use 2.0 or older).
I add a new contact on my phone as following code...
After that, I add phone numbers in the same way. It works as I am able to view the new added contact with following code :
Intent intent = new Intent(Intent.ACTION_VIEW, contactUri);
this.startActivity(intent);
My problem is that, after adding and viewing the new contact, I can't see it in Contacts application unless I synchronized all my contacts (I also did a search with the contact's name, found it, nevertheless it wasn't added in contacts list).
How can I programmatically update the contacts in order to immediately have my new contact added in Contacts application?
Android :: Can Update A List View In One Activity While Im In Another Activity
Oct 4, 2010I currently have a tab layout with 2 tabs, one tab with a list view and one with the option make strings so I can add them in the list view. Both tabs have their own activity because this made the code much more structured, and I dont have to repeat my self later.
Lets say im in the tab that offer me to create an string, and i press the update list button, how do I update the list view without startActivity()? If i use startActivity(), it starts List.java, and instead of displaying the list in the list view tab, it takes full screen, which defies the purpose of the tab view. In other words, the startActivity() steals the focus from the tab view of the list, and sends it fulscreen.
I want to update the activity in my list view tab, without starting a new activity that goes to fullscreen, and doesnt update the one in the tab.
Android :: Update Activity Textview After Changes From Another Activity
Nov 19, 2010I have an Android activity that, onCreate(), will query a database and display the query results in textviews on the UI.The problem that I am having is at some point, users can open another activity and update the database. When they go back to the original activity, I would like for the text views to update with the new database information (so, I will re query the database and display the info).Another thing that I am willing to do is to take the new input from the user (in the new activity) and directly update the textview in the existing activity (without having the existing activity re-query the database). But I'm not sure how to do something like that either.Can someone please inform me on the best way to go about doing this? The only solution that I have found so far has to do with broadcast receivers, but I'm not sure if that is best suited for what I have to do.

Create New Activity Or Update View Of Existing Activity?
Dec 24, 2012I am working on developing an app and I am not sure when should I use a new activity and when should I update the existing view.
For example, lets say I have a view that shows a multiple choice question.Now, when the user selects his choices and clicks on say "Evaluate", I want to show the same question view but along with the right answers and explanations for each option. So does that mean, I should send an Intent upon a click on Evaluate or I should just update the view (i am not sure how)?
If I send an intent and show a new screen, how can the user go back to the next question without displaying the answers? If I don't create an new activity, how can I update the existing view that is already displayed?

View 7 Replies View RelatedAndroid :: Call Activity From Widget?
May 30, 2009I've read through the Application Fundamentals three times today (and I had done so before), but I still can't quite wrap my ahead around the task concept. Or I guess I thought I understood it, but usually, the results I am seeing don't match up to what I would expect to happen (maybe a tool to see the current tasks/activities etc. for debugging purposes would be a nice addition).
I have multiple widgets from my provider in the Launcher desktop, and each is using a PendingIntent with a different URI as data (so they should be separate intents) to open an Activity.
I want there to be only once concurrent instance of this Activity that the user can access. So clicking the widget (1) , pressing HOME (2), clicking a different widget (3), pressing BACK (4) should bring the user back to the Desktop.
Now I did manage to do this using launchMode="singleTask" - the existing instance is brought to the top, onNewIntent() is called and I am pretty satisfied with it.
However, supposedly there are other ways to achieve an equivalent effect (say with having the activity restarted), and I'd like to understand why I don't seem to be able to get them to work: In every case, instead of seeing the home screen after step (4) (after pressing BACK), I see the *previous* instance of the Activity.
For example, if I read this correctly:
"There's another way to force activities to be removed from the stack. If an Intent object includes the FLAG_ACTIVITY_CLEAR_TOP flag, and the target task already has an instance of the type of activity that should handle the intent in its stack, all activities above that instance are cleared away so that it stands at the top of the stack and can respond to the intent. If the launch mode of the designated activity is "standard", it too will be removed from the stack, and a new instance will be launched to handle the incoming intent." http://developer.android.com/guide/topics/fundamentals.html
Then simply using using the following code to start my Activity from my widget should do what I want, no?
CODE:............
So in (3) My activity should be launched using FLAG_ACTIVITY_NEW_TASK by the launcher, which due to process affinity would find the existing task (which would consist of a single instance of my Activity), and launch the new instance on top of it. This explains what I am seeing. Why doesn't FLAG_ACTIVITY_CLEAR_TOP cause the existing instance in the task to be replaced?
Even setting android:launchMode explicitely to "standard", as mentioned in the doc quote above, this doesn't seem to change things.
I also tried android:finishOnTaskLaunch="true", but the behaviour is the exact same was just described with FLAG_ACTIVITY_CLEAR_TOP (which seems to be the exact same as when doing neither and really starting an activity without any special attributes).
I should mention that If I click the same widget in (3) as I clicked in (1), i.e. using the same PendingIntent twice, I do get the previous instance brought to the front (not restarted), but again, regardless of whether FLAG_ACTIVITY_CLEAR_TOP or finishOnTaskLaunch are being used.
I find this especially strange since the docs about tasks don't seem to mention the intent itself being relevant at all. Application Fundamentals does at one point say "For the default "standard" mode, a new instance is created to respond to every new intent", but it's not clear what "new intent" means then. Is triggering a PendingIntent multiple times through a widget not multiple "new" intents then?
I also tried various combinations of the other related options, but pretty much got nowhere.
