[android-beginners] draw() vs onDraw()
Hi, I am implementing my custom view in which I extend LinearLayout, add some children, and do some paintings over them. when I override onDraw method, I found my painting is done below children components but I want my painting o be over children component. Instead I tried to override the draw() method itself. It works and now, my paintings are over the children components. But I found JavaDoc says don't override draw(), instead override onDraw(). Is there a way to do what I want without overriding draw() itself (by overriding onDraw()). Also, why shouldn't I override draw() itself? thanks in advance -- You received this message because you are subscribed to the Google Groups "Android Beginners" group. NEW!

[android-beginners] Re-locating a dialog
Hello, I have an alert dialog which I got using AlertDialog.Builder (context).create(). When I call alertDialog.show(), it appears centered on screen (horizontally and vertically). Can I control its position? for example, I want to make it appear on top of screen to still show its parent window. How could this be done? thanks in advance. -- You received this message because you are subscribed to the Google Groups "Android Beginners" group.

[android-beginners] declaring a service
hello,
I am trying to run service example. I declare a service in a project
and want to call the service from an activity that exists in another
project.
in first project, my AndroidManifest.xml looks like this
http://schemas.android.com/apk/res/android";
package="com.mypackage.service_server">
the CalculatorService class extends the Service class and its onBind
method looks like this
public IBinder onBind(Intent intent) {
if(calculator == null) {
calculator = new CalculatorImpl();
}
return calculator;
}
The CalculatorImpl class extends Calculator.Stub class and
Calculator.java is generated from Calculator.aidl.
in the other project, in the activity onCreate there is a code like
this
Intent intent = new Intent(Calculator.class.getName());
boolean connected = bindService(intent, connection, BIND_AUTO_CREATE);
the method bindService returns false. what is missing in my both
projects?
note: the Calculator.java file is shared between both projects by a
symlink.
thanks in advance.

[android-beginners] Re: Get file name from Uri
thank you for this great help but unfortunately this isn't my case.
not me who created the cursor and iterate through it. I am just
receiving the Uri from another activity via an intent. and it isn't
good to iterate through all images to find one its Uri matches one I
received especially that I am not sure it will always be a Uri of an
image.
still can I get the file name?

[android-beginners] Developing software libraries
Hi all, I want to develop a class library for android platform. I mean developing a .apk (or jar. it doesn't matter) that doesn't contain activities but just a library that other applications can use its classes. can I? I think this is possible because I see a section in market called "software libraries". but I don't know how to start? another question please. now we have android-ndk. Is making this library making some native calls possible? if yes, does id differ from making native calls from normal applications. thanks in advance. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Android Beginners" group.

[android-beginners] Rooting ADP1 holiday edition
Hi, I got an ADP1 but not from google (from ebay) and I think it is holiday edition that was with a google employee. when I got it, it was on version 1.1. In my first day with it, it notified me that an upgrade to 1.5 is available and it downloaded and installed it. Now, I found myself don't have root on terminal. when executing "adb - d root" I get message "adbd cannot run as root in production builds". and also I can not access paid applications in the android market! I don't know if my phone now is a developer phone or a normal phone?!! Settings -> About Phone reports this Model number: Android Dev Phone 1 Firmware version: 1.5 Kernel Version: 2.6.27-00393-g6607056 s...@sandroid #1 Build number: CRB43 how can I have root permissions on shell? have I to re-flash the phone? if yes, what image should I use? will I lose my installed apps and my configurations I did on the phone? thanks in advance. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Android Beginners" group.

[android-beginners] Internet through ad-hoc wifi
Hi all, I saw many threads on web talking about using G1 phone as modem to give internet to laptops. but my problem is the reverse and I can not find any threads on web talking in this. I have a wired internet connection that I use with my laptop and my laptop has a wifi card. I could make a shared wifi connection that I am able to use from other mobile phones like Nokia N81. and the nokia phone can get internet through this connection. My problem is that I want my android phone (developer phone) to get internet using same approach (i.e through an ad-hoc wifi connection to the laptop that has wired internet access). can I? when I do a wifi scan from the android phone, it doesn't discover this shared wifi connection also entering connection ID manually doesn't work.. any help is much appreciated. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Android Beginners" group.
