I was wondering whether Androd can catch simultaneous Key Press. For example, a application does something when a user press HOME and MENU key simultaneously. Is it a possible scenario?

I am trying to implement a functionality when i press the VOLUME DOWN and POWER BUTTON simultaneously; i must be able to run a method code inside my Activity.
public boolean onKeyUp(int keyCode, KeyEvent event)
{
}
From my initial search; it seems that only one such key press event is acknowledged at a time in Android usng the onKeyUp method. Is it true?
In my Android phone, on simultaneously pressing POWER BUTTON as well as MENU BUTTON i am able to capture a screen shot.
Does this feature not acknowledge simultaneous key presses?
I have, for the time being, a custom view with a 9-patch image as a border.
That custom view is placed three times in a LinearLayout, so it looks like this:
+------------------------+
| CustomView |
+------------------------+
| CustomView |
+------------------------+
| CustomView |
+------------------------+
I have attached a click event listener to the View, so it is clickable. But then I click it, I cant see that I am clicking it - there is no change in color.
So, Im thought that I'd attach a "onPress" listener, and then change the background of the view but I couldnt find such a listener.
So, the question is - how do I create the behaviour on the View so I can see that it is being pressed? this is normally done in Android with a green background to indicate that it is now being pressed.
Implementing a service to handle connection changes and downloads. The service handles a queue of AsyncTasks, each representing a "download task". This way, we can cancel/pause tasks when connection drops, and also restore them when connection is reestablished. Since the threads AsyncTasks are run are not deterministic, how many ATs should I execute() at the same time?
I've read that I shouldn't reuse tasks. How can I achieve this pause->resume functionality then? Should I tell the thread to sleep? Should I make a no-op while if connection is down? I was trusting the cancel(true) method, which I've read is not reliable either.
My main DownloadTask is a subclass of AsyncTask that returns a new AsyncTask to be called when the connection is restored.
I am working on an art project with several other people that involves simultaneity and photography. We want to coordinate a series of events involving simultaneous photographs based on the Android system.
In simple terms, here is what we are proposing. Someone writes an app for Android Phone/Camera that makes the camera take a photograph at a predetermined time so that many thousands of people all take a simultaneous photograph. The art involved here is not only the synchronizing of the event to approximate simultaneity but also making "social networking" into an element of an art project.
Is there a limit on the number of simultaneous http requests of the form:
HttpResponse response = client.execute(request);
I'm interested in any official limit as well as practical ones.
(In a previous life, you had to dig deep to discover that WinMo only allowed three WebRequests to be open at a time.)
Let's say I have a list of 20 files to download on a background thread.
Should I: Download them one at a time, blocking the thread (but not the UI thread) to wait for each one? Start 20 threads each downloading one of the files?
I expect the answer may be somewhere in between, where I create C threads and work on the queue of N files, where C is a number like 3 or 4.
I suspect some of you here have already done some experimentation and know the magic number. In addition, I suspect there may be more efficient ways of doing what I'm doing than creating a new DefaultHttpClient for each request.
With reference to this discussion, does this mean that simultaneous Record and Playback with Mediarecorder and Mediaplayer is not possible at this point?

I am performing several https posts and http downloads from two different servers using AsyncTasks. The connections are fairly quick but I'm surprised to see that they are running synchronously instead of in parallel.
To be more explicit, here is pseudo-code for what's happening when I initiate a call to AsyncTask1():

View 2 Replies View RelatedI just installed the latest DialerOne (1.2.7.1) from the Market and find that the new simultaneous search of the call log and contacts is annoying in that it places call log entries at the top of the list, and tapping on them brings up the call history for that contact instead of listing their numbers so you can choose one to dial. I don't see any way to turn this off.Am I missing something?It would seem natural to have the ability to limit the search to the screen presented (search only the call log when the call log is displayed, or search only the contacts when contacts are displayed), but I have Dialer One display the call log by default, so that I can quickly call a recently called contact, or just start dialing to search, so this wouldn't work for me either.I would much rather go back to the way it used to be. Of course, I figured I didn't need to backup the previous version because after all, what could change? Now I have this, and the coloring of the digits on the keypad is weird, even after adjusting it as much as possible.
View 5 Replies View RelatedI have an android app, where in a list view for each element in list, I load an image from web in a separate thread. So if there are 8 items displayed in list view, activity will try to fire 8 different threads, one for each list item to load an image. As you scroll down the list, the number of threads may increase if the previous threads haven't finished executing.
I am curious to know how many simultaneous threads can a single android app execute in parallel? Is there a limit? I wouldn't expect these threads to cause a ANR over slow internet connection as they are independent? But it seems that ANR does happen and may be it's because app/device run low on resources, so spawning a new activity in UI takes more than 5 seconds which results in an ANR?
Any clues to how I can make responsiveness better on a slow internet connection will be appreciated.
If you don't need 3G on to do voice calls, then why would having it on not allow you to use your data connection while on a voice call?

However...
Was just on a call, tried to use the Android Marketplace. Couldn't. Got curious, and tried to use Google Maps mid call. Couldn't. Tried to use the internet during the call. Couldn't. Now, I'm on T-Mobile (UK) and have just come from a Nokia E71. With my E71 I could make a call and use Google Maps. Am I missing something or is this bit of multitasking somehow not possible?
I just wanted to check, e.g. on my Hero I can run GPS Tracker and press home and it will run in the background, play some music and press home and it will run in the background and go and do something else.
Are you saying the iPhone would have to completely exit the GPS Tracker to use another app or leave the GPS Tracker open and not do anything else for it to work?

Obviously connecting to 2 wifi connections is out of the question.

View 1 Replies View RelatedI briefly owned a blackberry not too long ago so that I could handle work e-mail on the go. However, I was disappointed with its e-mail capabilities (or lack thereof) and quickly got rid of it.Due to the nature of my work, I use several different e-mail accounts and I need to be able to access them using imap so that when I move or delete an e-mail locally, it gets updated on the server. Can the G1 accommodate this? For each e-mail account, can you specify things like imap and smtp server?I use a gmail account, a google apps account and three other accounts with other e-mail providers.
