I'm trying to implement similar behavior as the native phone app. When a User is in the applications menu/drawer (place that lists all applications) and receives and incoming call, after the call has ended the User is returned to the Android Homescreen. How do I redirect activity to the android homescreen like the phone app for that specific case.

Is there an Event that is fired when an widget becomes visible on to the homescreen. I didn't mean at install time, I mean if the user changes his homescreen by wiping the surface of the phone. The background of this question is that I setup a timer in a service inside the widget that gets updates from a url but that should stop if the widget is not on the current homescreen.

Specifically I want the vlingo app icon to open vlingo and start speaking right away. Similar to the vlingo widget, but I need to do this with an icon shortcut.
What I am trying to do is emulating the "Home" button which takes one back to Android's homescreen. So here is what causes me problems: I have 3 launcher activities. The first one (which is connected to the homescreen icon) is just a (password protected) configuration activity. It will not be used by the user (just admin) One of the other 2 (both accessed via an app widget) is a questionnaire app. I'm allowing to jump back between questions via the Back button or a GUI back button as well. When the questionnaire is finished I sum up the answers given and provide a "Finish" button which should take the user back to the home screen.
For the questionnaire app I use a single activity (called ItemActivity) which calls itself (is that recursion as well when using intents?) to jump from one question to another:
Questionnaire.serializeToXML();
Intent i = new Intent().setClass(c, ItemActivity.class);
if(Questionnaire.instance.getCurrentItemNo() == Questionnaire.instance.getAmountOfItems()) {
Questionnaire.instance.setCompleted(true);
} else Questionnaire.instance.nextItem();
startActivity(i);
The final screen shows something like "Thank you for participating" as well as the formerly described button which should take one back to the homescreen. But I don't really get how to exit the Activity properly. I've e.g. used this.finish(); but this strangely brings up the "Thank you" screen again. So how can I just exit by jumping back to the homescreen?
I am quite new to Android yet, and I have an application that has a webview on it. I need to know when the webview finishes loading a page that has a random number of redirects (sometimes to the same page, and the order of the redirects also change), so I can remove the Splash Screen only when there is a fully loaded page. On the webviewclient the onPageStarted and onPageFinished functions are called once per each redirect, as is the onNewPicture (even though the screen is always blank during the redirects). So I can't be sure when it's called the last time (page actually loaded). I also tried using the onLoadResource to count the number of resources loaded (dangerous and unreliable approach, but I am getting desperate here), but this also failed, since after the page is cached, it is called only one or two times. That is one big puzzle I am unable to solve using what I know so far, can anyone please help me?

View 2 Replies View RelatedI have an application that must create a database and if that fails, then no sense moving forward. I've built an AlertDialog and show() it but it never displays. The logic falls through and then barfs because of the missing database.What is the right/best way to throw up a message and halt the activity? The code below executes fine (meaning the show() occurs while debugging and it falls to the next line) but the UI never displays this alert.BTW I realize the throw might not be the most graceful but I'm not even getting that far so.

View 3 Replies View RelatedI was wondering if anyone understood how to make your application be displayed when you unlock the screen. I have an application where the user turns on a Bluetooth device, it connects to the phone, and the user should be presented with a UI. Having them hunt for the app or using the notification menu is not a workable option (too much work and not the obvious behavior).
The problem is that:
When the screen is unlocked:
- you can popup the activity from the background service when Bluetooth connects to a device
- User is happy because the UI is right there
When the screen is locked:
- The application gets started but is destroyed
- User unlocks the phone and nothing is there but the homescreen
One work around would be to disable the keyguard when the application gets woken up but the nuclear option is a pretty bad option. I know the standard Android assumption is that you shouldn't do this. In the normal case this behavior is fine, but in this case I explicitly did something I want the phone to respond without adding more work for the user to do. As per Google's guidelines if you don't like this behavior there can be an option for you to turn this off or you can not use the application.
A few more details, so after looking at this a bit more the problem isn't necessarily that you can't have an activity running when the screen is locked, unlock and expect it to be waiting. That does work if you do something like the following: lock your device run an app through Eclipse while the phone is locked/off unlock and it will be waiting for you.
But in the case the Activity is already running and I'm brining up a new window (which happens to be a transparent one, saying you're connected and asking what they want to do).
The problem is that it gets killed
CODE:..................
The setup here is as follows:
MyBackgroundService is a serivce that handles Bluetooth state (waits for connections, turns on Bluetooth if the user starts the app, etc.). It triggers a popup BackgroundPOPUP activity that runs a ViewFlipper.
MyBackgroundService starts BackgroundPOPUP through an intent.
BackgroundPOPUP is an activity with a Translucent theme (Theme.Translucent to be precise), it shows a ViewFlipper with some instructions and presents some options.
Here is my code. I'd like to pass a boolean to the activity i want to start.code...
View 1 Replies View RelatedI am creating an alternative keyboard. In order to help users understand how to set up the IME after it is installed I have added a simple Main Activity that appears in the Application Launcher with set up and usage instructions. I also have a preferences Activity and I want the user to have an option to hide or show the setup instructions Activity if they don't want to see it any more. My question is how best I can do this? I am assuming if it is possible it would require overriding the IntentFilter for the setup instruction Activity. I have experimented with this and read through the Intents and IntentFilter documentation but I can't see how to do this.
View 2 Replies View RelatedI recently released an update to my application (about a week ago).

Did anyone here have similar reports recently?
I understand that trying to capture home button clicks is a hack, but I need to atleast close my current activity when the user clicks on home button. Is there anyway I can tell the system to close this activity is the user clicks on home button? If so how can I do that? I need to do it as I am listening for location updates and I want to stop the updates and also need to trash any location that was available to me previously. I need to do this just in case any user while in that activity clicks on home button and changes the location settings.

I have to press BACK one more time to go back to the MAIN activity.I would like the app to go back directly to the MAIN activity by pressing BACK only once.

View 4 Replies View RelatedI have a Service that downloads a file from the internet. What I want is for the response (an InputStream in this case) to be handled by a custom handler that can be switched (like a strategy pattern) but I can't figure out how to do this. So basically the User of the API would be able to plug in different handlers for the response, some would parse XML, others might save files etc. I realise I could pass through the activity context and execute the method from this (given some interface) but I don't want to do this obviously, in case the Activity is closed in the meantime while the file is still downloaded.
UPDATE - I just had one idea it will work sort of but has problem if the DownloadRunnable gets changed between executions of the downloads.

interface DownloadRunnable {
void run(InputStream stream);
}

View 1 Replies View RelatedI have an Activity with a list that is bound to a ListAdapter reading data into a ArrayList from a database. All is well when the data is first loaded. While the Activity is open and the list is being displayed it is possible and likely that the data in the database will be updated by a service but the list does not reflect the changes because the ArrayList does not know about the changes. If the Activity is no longer in the foreground as would be the case if the user goes to the home screen and then is brought back to the foreground I would like for the Activity to not display what it did prior but rather reload the data using the ListAdapter the view is bound to. I think something needs to call finish() but I am not sure what.
This is what I have in the Activity.

I'm having a problem with unlocking my phone. Some of my friends tried to unlock the pattern but after 20 failures the phone blocked. Now I have to submit my google login so I can get back on it. The problem with that was that I was on vacation abroad so my 3G and wifi were both turned off. I've read about other problems like this and came to a point where I was trying to turn on my wifi with adb. I found that I could use the command "svc wifi enable" and I tried this several times, every time with the same result: I think the command starts but then gets killed before it finishes.
View 9 Replies View RelatedI've got an Android activity which grabs an RSS feed from a URL, and uses the SAX parser to stick each item from the XML into an array. This all works fine but, as expected, takes a bit of time, so I want to use AsyncActivity to do it in the background. The line items = parser.getItems() works fine - items being the arraylist containing each item from the XML. The problem I'm facing is that on starting the activity, the ProgressDialog which i create in onPreExecute() isn't displayed until after the doInBackground() method has finished. i.e. I get a black screen, a long pause, then a completely populated list with the items in. Why is this happening? Why isn't the UI drawing, the ProgressDialog showing, the parser getting the items and incrementally adding them to the list, then the ProgressDialog dismissing?
