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.
I took a look at AccountManager, but that doesn't seem to be the right place to look.
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 have noticed a lot of the use of @Override in Android example code. I thought that all Java methods were by default "Virutal"?
What then does @Override do?
Example:
private class HelloWebViewClient extends WebViewClient {
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
}
Android: How to Add Static row in list view
I have a requirement where i need to add the Static row as first row in list view
Thanks in advance for help..
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.
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?

Does Android come with a way to do Full Text Search?
I know is it not even possible to search contacts by the notes field, being Google the search company, but I would be disappointed if there is no API for that.

Hi,
I have a ListView in my android application.
If I flick up/down the ListView, which method will return my 'selected' element in my list View? How about if I use the track ball to navigate up/down my list view, which method will return the index of my selected element?
Thank you.

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,
If someone asks me the below questions
What an Android Framework is?
What does it do?
How should I answer?
Also what is the role of API's such as Activity Manager, Location Manager etc in the Framework?
hello I think the title says it all. I need to accomplish this result in android but it looks like there is no easy fix to my problem. Just to clarify a bit more: if I had to do it in html css I would write something like
<img src="Image URL" style="float:left; margin-right: 5px;" />
got it? ;)
thanks guyz
Starter question: My "Hello World" attempt won't run, ("No compatible targets were found"), I think this is bacause I selected the latest version for my project (2.2), and the highest AVD version is 2.0.1. Does this make sense? Can I change my project version (haven't been able to find a way to do this), or do I have to start again? If the versions are not backwards compatible, what is the best version to use for the majority of Android devices out there?
Thanks
I have an iPhone application and I am porting it over to Android.
I have a service/controller that spawns new threads to perform some network tasks.
I use performSelectorOnMainThread in my iPhone app. How can I have my Java app do the same or similar thing?
I want to quit application in Android. Just put a "quit" button, which kills my app.
I know I shouldn't do this. I know that this is not the philosophy of the OS.
If you know how it can be done, pls share.
In the app, I have many opened activities, so "finish()" will not do the job.
Thank you for your information in advance.

Here's my story.
I downloaded the NotePad tutorial project exercise files.
I created an Android project based on the tutorial files for the completed exercise (located in the Notepadv3Solution folder)
I run the project and bellow is a screenshot of what appears:
It seems like it's not working properly.
Could it be because I'm on version 2.2?
