Can I create an activity for a particular task without that task coming to the foreground?

Here's my use case: The app starts at a login screen. You enter your credentials and hit the "Login" button. Then a progress dialog appears and you wait for some stuff to download.

Does an Intent's extras still get flattened into a Parcel even if the new activity is being started within the same task?

I was wondering... So if you start a new activity via an intent, the intent has to be serialized and deserialized because you may have to send the intent to a separate VM instance via IPC. But what if the PackageManager knows that your new activity will be created on the current task? It seems like a reasonably Googly optimization wou...

Do Android/webOS devices support multi-touch Javascript events?

On iPhone, iPod touch and (presumably) iPad, Apple has multi-touch event handling available via JavaScript in Mobile Safari. I know the Nexus One recently added multi-touch support via an update, and I believe webOS is also multi-touch enabled.

Android - Wrapping a complete line, not just words

Hi all, Am currently writing an App for Android and in one of the layouts I have a users name and beside it a couple of tags.

However I sometimes get lag spikes in the game, and I know its not the GC because I have run the ddms tool, and eliminated all the GC calls. However, I do see alot of backgro...

Android: videocamera, limit length of videos taken

I'm working in Android and starting the video camera activity using ACTION_VIDEO_CAPTURE. Is there any way I can limit the length (in time) of the videos the user can take?

How well does knowledge of J2ME generalize to other mobile platforms?

I'm considering taking mobile phone software development course at my university. The course uses J2ME with an emulator. I'm interested in software development for mobile phones, but I get the impression that J2ME is somewhat stale and limited in comparison to the newer platforms like the iPhone and Android.

How to stop an activity with GL view. Application not responding

I have an activity that I want to programmatically stop after some elapsed time. I have a GL view running.
