Why can't I use the Context of a Service to display an AlertDialog ?
I can do it with Toast!
I have issue with displaying AlertDialog from Service. I am able to display custom layout window using Toast or using WindowManager(TYPE_SYSTEM_ALERT or TYPE_SYSTEM_OVERLAY). But, I do not want to use custom layout, I prefer to use nice AlertDialog GUI directly.
Scenario:
Running Service. No active Activity present. On some external event, Service sends Notification
When user press Notification, Service is informed via PendingIntent and AlertDialog should be displayed (created with AlertDialog.Builder(this))
Error: ERROR/AndroidRuntime(1063): Caused by: android.view.WindowManager$BadTokenException: Unable to add window -- token null is not for an application. Searching for the answer lead me to impression that I am trying something that is currently not possible (Android 2.2). Or maybe it is.
I've been working at this all day, and I'm really close but just can't get this to work. I have a button that pulls up an AlertDialog populated with saved entries that include Name and Price. Right now, I can click an item in the Dialog and have it automatically fill in the Name and Price fields in my activity. I want to also be able to long press an item and receive an option to delete it. This is my first try at an Android app, and a lot of this is repurposed from the Notepad Tutorial. Two things I can't figure out:
1) Is my registerForContextMenu sufficient/correct?
2) What am I doing wrong with my onCreateContextMenu? Code...

View 2 Replies View RelatedI have a service running a background thread. What I'd like to do is to show an AlertDialog initiated from my background thread. I know that this is not the recommended way of notifying the user and that it interrupts the workflow (as they can pop-up in any application at any time) but it's a suitable way for my use case. There is a handler registered with the background thread and showing a Toast notification withing the handler works fine. But after switching to an AlertDialog nothing happens anymore. My showDialog logic is silently ignored. No Dialog window appears, no log entry. It's a bit strange as I'd expect at least a log entry saying that I'm doing something wrong or whatever. Are there any limitations for showing an AlertDialog initiated from a service background thread? Some people seem to recommend a Dialog themed Activity to get a similar behavior.

Is it possible to check some condition inside onCreate() of an Activity and display an AlertDialog?
I am creating an AlertDialog anonymously in Oncreate() and calling show on that instance but the AlertDialog is never displayed.
So I'm working on a service that will handle requests to send data to a socket.I've done socket programming in a service before, but only within the same application. I'd like this to just sit and do nothing until any application wants to give it data to send. That's all well and good.I have register an intent filter and the usual stuff and can process the data. But I want to process the data coming from different activities in different threads (subsequent calls from the same application will be computed on the same thread).Is there a way to get the calling package or app or whatever? I'd prefer not to require passing in an identifier as an extra to prevent spoofing. (It's not a serious security concern, it's just each application needs its data processed in the order that it's received.)
View 1 Replies View RelatedI am trying to figure out what is the best way to go about creating dialogs. I can either create my own Dialog class (which, to me, is more clean and organized), or I can use AlertDialog.Builder (which would be done inline, and funky looking)... What are the positivies and negatives of either implementation?

Once the scan is done control of course returns to the code behind Screen-A and I do some other work before calling Screen-B. Problem is the screen is black during this work period and I cannot determine the proper context to use to display a "working..." Toast/msgbox.

List 1 -- with different background

I have two ArrayAdapter<String> to handle the values. I have issue in the display. my xml file is structured as
<Linear Layout>
<ListView> </ListView>
<ListView> </ListView>

its displays the two list items by dividing the screen into two equal parts and scrolls within the list individually.
I wanted the List 1 to be displayed fully and then followed by List 2 and also it should screen should be scroll not with in the list but full screen so that List 2 could be seen below.

View 1 Replies View RelatedIn my android application, I am using the tab view and so I have two tabs: parameters and results. the user enters the various parameters on the first tab and then switches to the second tab to view the results. i have a service that performs some long-running calculations. the user enters parameters on the first tab and hits 'calculate'. They can make adjustments and hit 'recalculate' and the service is updated with the new parameters.
As these calculations progress, I want the user to be able to switch to the results tab to view the results of the latest calculation. They would then view the results and be able to switch back to the parameters tab to make adjustments. I can think of two approaches: register the 'results tab' with the service and when the service reaches a milestone, it calls directly to the 'results tab'. have a timer running in the 'results tab' and have it query against the bound service on a regular interval and update accordingly.
How can I launch a contextmenu from a contextmenu? I'm trying to replicate the MediaPlayer action that happens when you long click a song, then click "Add to playlist" in the resulting contextmenu. When you click that menu item, another contextmenu pops up with "Add to playlist" as the title, and "Current playlist", "New", and however-many-playlists-you-have defined after that.
View 4 Replies View RelatedI'm trying to create an application that can use the android as a fax machine, IE Send a picture as a fax or receive a fax and save as a picture. So far I'm starting from the ground up and making sure I can intercept a call at the users discretion. I have an Receiver registered in the Manifest of my program with a filter of Phone_State which flags when the state has changed(IE incoming call).
So on my BroadcastReceiver I'm trying to have an AlertDialog popup prompting the user to either accept as fax or call but the AlertDialog seems to throw a android.view.WindowManager$BadTokenException Error when it has an incoming call. My code is just simple an onReceive(context arg0, intent arg1) and I pass the arg0 to the AlertDialog...

From what I have seen in the AlertDialog code, it passes the context as well as a Window and WindowManager, which I believe is why it's crashing, is there a better way or something else I should be using which might overlay the call screen?
I have a TabActivity with 3 tabs. Each tab contains its own Activity. When one of the contained Activities pops up an AlertDialog, there are actually 3 dialogs created. The dialog has a Dismiss button and it must be pressed 3 times to finally dismiss the 3rd dialog.

Is there a way to click on a dialog, or get Views belonging to the Dialog in unit tests?The only way I could come up with is to keep a reference to the dialog and have my Activity implement a getter method to let testcases access the dialog. Is there a better way that doesn't require changing my production code?
