how powerful is Bluetooth programming on Android? is it possible to add new protocols and encryption techniques? or even change in the current protocols? does it support bluetooth 2.1+EDR?
Android is an open source operating system that is modified by cell phone vendors (HTC, Motorola, etc.). Modifications include the user interface, drivers, and other proprietary extensions.
Traditionally, product lines have been a suite of products or services that share a core set of functionality and are modified for different domains and markets.
Does this still qualify as a product line?

I'm trying to build a voip application on a new android device, i use AudioRecorder to read the microphone but I'm getting no valid results, just white noise.
This happen only on this new device(other work well) and this is probably because this device has PTT ability.
Is there some workaround to avoid using AudioRecoder to receive streaming data from the microphone?
Thanks.

Is there a way to change the sync settings of a Gmail account programmatically with an Android app? For instance, I'd like to enable/disable syncing of a Gmail account from my app, without the user having to do anything.

What would be the best way to write an app for the iPhone OS and the Android OS that allows access to a web blog (posted on blogspot.com)? Are there ways to manipulate the incoming data from the website to fit the UI of the phones, or will I have to re-do a lot of the blogs?
Any help would be nice! And thank you in advance!

I am attempting to learn how to develop on the Android platform but do not quite understand the relationship between Activities and Views, because according to the documentation an Activity is link to a UI object that the user can interact with, but if this is the case where does the whole idea of Views come in?
There is probably a very basic explanation but I would appreciate a few pointers all the same. Thanks
I've got a string:
public://imageifarm/3600.jpg
How can I extract the
imageifarm/3600.jpg
Part out using android?
What I've tried so far:
URL drupalQuestionNodeImageURI = new URL("public://imageifarm/3600.jpg");
Log.d("TAG", drupalQuestionNodeImageURI.getPath());
but it throws this exception:
09-16 17:24:39.992: W/System.err(3763): java.net.MalformedURLException: Unknown protocol: public
How can I solve this?
I know I can use regular expressions but that seems to defeat the purpose of URL(URI) in this case.
Hi.
I need to obtain the velocity of an android device, based on the accelerometer values. I made a code that allows me to get the accelerometer values, and then I calculate the velocity, using the formula:
v = v0 + at. (vector calculation)
My problem is that my velocity only increases and never decreases. I think the problem is that the device never gets an negative acceleration.
Can you help me with this?
I'm used to handle graphics with old-school libraries (allegro, GD, pygame), where if I want to copy a part of a bitmap into another... I just use blit.
I'm trying to figure out how to do that in android, and I got very confused.
So... we have these Canvas that are write-only, and Bitmaps that are read-only? It seems too stupid to be real, there must be something I'm missing, but I really can't figure it out.

got it? ;)
thanks guyz
