Android : How Does Froyo Display A Dialog Atop Home Screen?
Jul 2, 2010
I upgraded my Nexus One a few days ago with 2.2 (Froyo). This morning when I went to use it I saw a Dialog sitting atop the home/launcher screen notifying me that an update was available and that I could choose to upgrade now or later. My question is, what API mechanisms is this using to show a Dialog (perhaps an AlertDialog) atop the home screen? Having written an Android app, it was my understanding that Dialogs could only be shown atop an Activity, and that a Service cannot show a Dialog (only a Toast).

The dialog("android.app.Dialog") normally pops up in the center of screen. Can we make the dialog to come in the bottom of screen.

I was wondering if anyone can tell if how to pop a dialog screen up over a native Android screen? I currently have an application that traps an outgoing call and stops it, I then want to pop up a dialog that would take over from the dialler screen and alert the user that there attempt to call has been blocked and allow them have some new options from the dialog.

Does anyone know of a widget that will display the contents of the inbox on the home screen? So that, without opening gmail I can glance at the phone and see the 3-5 most recent messages, sender and subject? I have looked all over the market and can't find anything like this.

How do you change the way the home screen is being displayed? Not the wallpaper itself, but the size and shape of the clock and whether it's even there or not.

The old symbian phone displays the area/location on home screen, even if the GPS/GPRS is not activated. This is provided by the network operator. I am missing the same in my Android phone.
Even My Location option does not display the area/location on homescreen, it displays only the Network operator name.
I tried looking for apps, but all are for displaying the operator's name but not location. I can check my location using any GPS application, but those does not display it on my home screen along with Operators name. I want it similar to my Nokia N81 where the operator name and area name are displayed.

Not sure if anyone else is getting this, but every once in awhile when I try to go back to the home screens the HTC logo comes up and a "Loading" window comes up for a little while before I can access the home screens. Anyone know what could be causing this? This never happened before froyo. At first I thought it might be from widgets that I have saved to SD but I don't have any apps with widgets saved to SD (I don't think). Ideas?

Noticed yesterday that on the homescreen when the phone was locked that a missed call and voicemail notification appeared as pieces removed from a jigsaw overlay of the background homescreen image. Hadn't seen that before. Is that a default thing or can I change it (did look rather cool though). I usually use the pattern lock rather than the default swipe lock, so I'm wondering if it's to do with that default setting.

I need to display an alert message for no more than a half a second. As I understand it, Toast only has 2 available durations, with no way to alter them. Correct me if I'm wrong. Which leads me to sing the AlertDialog. What would be the best way of displaying a dialog for 500ms and then dismissing it?

Yes I know there's AlertDialog.Builder, but I'm shocked to know how difficult (well, at least not programmer-friendly) to display a dialog in Android.
I used to be a .Net developer, and I'm wondering is there any Android-equivalent of the following? code...

I have a situation where I have a broadcast receiver which creates a notification and the notification, when selected, sends the application to a new Activity with a yes/no AlertDialog. I have two questions:
1. Is it possible to show an AlertDialog (from the notification) without sending the user to a new Activity? (This way the user can click No and resume working in any other application)
2. A ListActivity already exists in this application. If the user clicks yes the user should be send to this existing Activity. Currently I'm dong this from a new activity in the application using: startActivity(new Intent(this,MSPMain.class)); I believe this is making a new instance of the Activity rather than simply showing the existing Activity. Is there a way to show the existing Activity without making starting a new one?

I have a webview I'd like to display as a dialog. I'd like the webview to fill the entire screen, except for a button below it that I'd like to stay at the bottom of the dialog regardless of how much content is in the webview. Currently my webview fills up the dialog just enough to push the button off the screen. I'm sure this is something pretty easy but for the life of me, I haven't been able to find the magical combination of layouts, views and attribute values to get it to play nice. Just to be clear, I've gotten it so the button floats over the webview but I'd like the webview to stop just above the button and scroll, if that makes sense.

I have an application that is designed to pop up a question when a phone call ends using a BroadcastReceiver and a PhoneStateListener.
My problem is, when a call is received while the user is not currently using my application, the dialog is not displayed until the application is manually started. I would like either for the dialog to be displayed on top of what ever context the user is currently in, or that my application will be focused.
How is this done?

So this is related to a question I asked earlier. I am trying to display an alert using a specified layout. My layout is:
And the code to call and show the alert dialog is..
When I run it I get an error saying:
Uncaught handler: thread main exiting due to uncaught exception
android.view.WindowManager$NadTokenException: Unable to add window -- token null is not for an application
I've looked through the android development site and can't figure it out. I think I'm just missing something obvious but the fix isn't jumping out at me. How can I get this alert dialog to display?

I would like to intercept outgoing calls and pass them to a VOIP application. I see that the Google Voice application has a feature for displaying a question before each call is actually initiated. It provides the user with the choice:
Initiate call via Google Voice
Initiate call via standard call
I would like a way to do something similar with my application (so that not all calls have to be routed through it). At the moment, I can intercept CALL events via a BroadcastReceiver, however, these are not allowed to open dialogs (thus making it possible to display the choice).
What is the best way of achieving this goal?

Whenever I am using any app and press the home button, the home screen blacks out for a few secs and it takes around 10 sec to get all the icons back and before I can start using my phone again. I am using a non rooted mytouch 3g.
This problem does not happen if I exit an app by pressing the back button. It becomes very annoying at times.
