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.
I'm looking to create a simple form with some textfields and a button using the Android SDK. Could someone point out a good example or tutorial for getting started?

Hi
I recently started using eclipse and an AVD emulator to develop android apps for a droid. Everything is going fine, except when i type in the emulator it returns chinese characters. My location is set to en-us, so not sure what is going on.
Any thoughts?
(Newbie to Java, old time C# guy.)
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;
}
}

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 an android app that periodically, say once a week downloads content from a server in XML. The content is used by the app, different Acitivities use different parts of the content.
My question is a design one, should I save the data in SQlite or just keep it as an XML file, which one would be faster to read?
The app can only use one content piece at a time, which means subsequent XML content downloads replace the old one.
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.

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?
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 have a large editText that no matter what I try, won't center. I have tried putting it in a horizontal and vertical linear layout and then setting that gravity to center because setting the imageText's gravity to center, it still hugs the left of my activity.
<EditText
android:id="@+id/editText1"
android:layout_width="250dp"
android:layout_height="wrap_content"
android:ems="10"
android:gravity="center"
android:lines="8"
android:maxLines="8"
android:minLines="8" >
</EditText>
And here is what it is doing:
I want a TextView to have a rounded border. This can be done by using a drawable, specifying a shape in the drawable, and then using the drawable as the background of the TextView. android:background="@layout/border" Also shown here
However, my TextView already has a background color (which is gray) and thus I'm unable to use the above method to set a rounded border.
Is there any other method to do this which allows the background color of the TextView to remain gray and also surrounds it with a rounded border?

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?
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.
