As MrChaz wrote, you'll definitively need the Camera permission and
for checking if you are still getting exceptions, try this:
Camera cam = null;
try{

}catch(Exception ex){
Log.e("Camera.open()",""+ex);
}
if(cam==null){
return;
}
//it is very important that the camera be released by the app that
opens it.
try{//try-finally block to ensure that the camera is released
try{

[android-beginners] XML Layout Language
Does anyone know a link to the specification for the XML Layout? I'm looking for a description of the tags etc. Since I'm new and just learning, a simplified version would be nice, focusing on the most common tags. Everything I read now is vague. If not, here's some questions I have that are more specific. >From the layout section of the DevGuide: http://schemas.android.com/apk/res/ android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical" > - What does xmlns mean? - What is the android: sytnax all about? - What does the "http://schemas.android.com/apk/res/android"; do? - Can you create your own Layouts like the "LinearLayout"? - Is there a list of available components like "Button", "TextView"? - What does the @ symbol do? - Can I edit this directly in Eclipse with a graphical editor rather than manipulating text? I'm sure these are probably simple questions answered somewhere, but I just can't find the specification and I'm so new I don't seem to be able to find the info.

[android-beginners] How to Drag-n-Drop an Image from source to target ImageButton
Hi
I have a TableLayout with various Image buttons. I'm using XML layout
instead of a custom view class. I'd like to move an image from one
ImageButton object to another like moving a chess piece to a target
square by capturing a piece.
I'd like to know how to obtain the target ImageButton object based on
current(target) coordinates represented in the MotionEvent object and
draw the source image on the selected button? I'm using the following
listener code snippet to capture the source view and the event.
class BoardListener implements OnTouchListener {
@Override
public boolean onTouch(View v, MotionEvent event) {
switch(v.getId()) {
case R.id.a8:
}
}
}
Appreciate your input
Thanks

[android-beginners] Can I just redraw part of the view without clean the existed pic?
Hi, I want to draw more pictures to a canvas of a view when I touch the screen, such as when a touch event happened, I will draw a number in the canvas, then a touch event happened again, I want to draw another number in a different area in the canvas(I need keep the first one I drawed just now). so I just draw the numbers in onDraw, and call Invalidate() when touch event happened. But the problem is when I call invalidate(), I need draw all the numbers again, it will waste some effort. so I want to know how to keep the original pic and just add the new part to the original one anyone knows? Thanks. P.S. some one said I can use invalidate(x,y,top, bottom) to invalidate Rect of a canvas, but the problem is I need redraw in area1 and area2, may be more areas, I can not give a specific area when call invalidate (x,y,top, bottom) ... --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Android Beginners" group.

2. In the top part of the html page written "The file containing the
source code shown below is located in the corresponding directory in

sample code in that directory. Is the information wrong or my system
is incomplete?
3. What do I get (see) when the program run normally?

[android-beginners] My First Custom View Totally Busted
Hi all -
I'm trying to get up to speed with custom views, and I took most of
this code from examples, but I cannot get it to do anything. When I
run the code below in the emulator I just get a blank screen, and when
I set debug breakpoints it shows that onDraw() never gets called!
It's got to be something dumb and simple, but I don't see it. I'm
just trying to get a circle painted for starters. I even tried adding
an "mv.invalidate()" call to the onCreate() method to try and get it
to redraw but nothing changed. Help!

http://files.getdropbox.com/u/1040020/right.png
But I get this: http://files.getdropbox.com/u/1040020/wrong.png
My code:
TableLayout layout = new TableLayout(this);
for(int i=0; i < 10; i++) {
TableRow row = new TableRow(this);
for(int j=0; j < 10; j++) {
TextView tv = new TextView(this);
tv.setText(String.valueOf(i*10 + j + 1));
tv.setGravity(Gravity.CENTER);
row.addView(tv);
}
layout.addView(row);
}
What am I doing wrong? Can I achieve the same effect doing another
thing? (Other layouts, using fixed sizes for each TextView...
whatever)
Thank you in advance :)

[android-beginners] XML Layout Specification
Here's a layout from the DevGuide: http://developer.android.com/guide/topics/ui/declaring-layout.html http://schemas.android.com/apk/res/ android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical" > - What does xmlns mean? - What is the android:xxx sytnax all about? - What does the "http://schemas.android.com/apk/res/android"; do? - Are there other values I might choose? (ex. "http:// schemas.android.com/apk/res/iPhone") - Can you create your own Layouts like the "LinearLayout"? - Is there a list of available components like "Button", "TextView"? - What does the @, the / and the + symbol do? - Can I edit this directly in Eclipse with a graphical editor rather than editing the xml text? That's a lot of questions. So let me sum these up into one simple question: Does anyone know a link to the specification for the XML Layout Language for Android?

[android-beginners] tools/android fails with runtime error java.lang.AssertionError on ubuntu 9.04
I just had an issue and fixed it myself, so I thought I would put this out there in case anyone else has the same problem. I am running ubuntu 9.04. I just downloaded the android sdk for linux and when I tried to run "android list targets" I got a java runtime error. I eventually figured out that my system was not using the official sun version of java. I ran "sudo update-alternatives --config java" and used that utility to switch to the official sun version and the runtime error went away. Hope this helps someone. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Android Beginners" group.

[android-beginners] Re: Practical questions
As a person has used Windows Mobile/CE devices for over 6 years and been developing for the mobile platform for over 4 years, I think I can offer some perspective... First, regarding G1 availability, costs and restrictions (since to date anything else is largely vaporware or just launching)... Users always can choose the grey market (purchasing from a source other than T-Mobile). Today, you might be required to purchase for $180 from T-Mobile with a 2 year contract, but you can get a phone without a contract for somewhere from $210-280(street price). T-Mobile service is required to activate (T-Mobile seems to be doing a good job of closing all efforts to jailbreak), and although no pre-paid plan is supported, you can get on a month to month contract (requires both a voice and a data/messaging plans). So, it might be more expensive than pre-paid but not necessarily tremendously moreso unless you never plan to use the phone in a "normal user" way. Usually, with hardware you get what you pay for. Ever actually get your hands on a Sciphone (with its supposedly "android-like interface")? You're not getting nearly the same thing... Features like slide-out keyboards are expensive. I haven't compared to the iPhone 3GS yet, but earlier models had their warts compared to the G1, too... Like lack of support for multi-tasking applications, poor camera picture quality. Support for multi-tasking might be desirable but it also can be demanding... drawing down power quickly, maxing out resource utilization. Whatever model of hardware and software you might want to compare, you'll likely find feature advantages or lacking every time. So, it's whatever floats your boat which should determine whether you choose an iPhone, Blackberry, G1 or anything else. BTW - That's some trick running J2ME on Windows Mobile. There's only one phone that supports that configuration with decent performance(not the one you mention) which severely restricts that market (unless performance is not an issue). IMO, Tony - Original Message - From: A Sent: Thu, 6/11/2009 5:56am To: Android Beginners Subject: [android-beginners] Practical questions Hi all, I have some practical questions. I might be interested in coding for Android. I have some J2ME programs that I could port that are very useful. But I am wondering, why bother? Consider: 1. Looking at the documentation for Android it seems to me that the learning curve for working with Android is large. 2. Looking at the available phones they are all about $500 without a contract. We're in a Recession and $500 is a lot of money. Compare that to my 3-inch touch screen Sciphone i68 which was $100 and has MIDP support. 3. I don't do contracts. I have heard that Android phones are hobbled by the requirement that I'd have to have a contract. I use prepaid exclusively to keep my phone bills down. 4. No contract means no data plan. 5. I can get a Windows Mobile phone for $260, called the CECT M88+. It will run native apps and J2ME. That's half the cost of an Android phone. 6. Regular consumers know we're in a recession. They are going to avoid expensive phones and long contracts more now than ever. Will $500 luxury Android phones take hold? I'm skeptical. 7. I am not someone who is easily impressed by Google. There is no "wow" factor for me in using Android. I'm entirely pragmatic.

On this related subject, I may have a need to create the APK using only the command line (not using Eclipse). I didn't seem to notice that the Android SDK supports this, am I missing something?

[android-beginners] Re: starting the htc dream
I just went through all that. I wasn't able to get unrestricted root access to implement any of the workarounds posted on the Internet. I tried using Telnet and remote ADP, T-Mobile seems to have closed that security hole on all current Android images. In the end, I setup my Google account beforehand, then waited for T-Mobile to activate my G1 upgrade (their funky billing system doesn't support upgrades in the middle of a billing cycle unless you're willing to pay an extra month in advance). Also, when connecting to the Google servers, you only enter the mailbox name without the "@gmail.com" I don't know what your options are in Canada, if you insist on not signing up with an authorized carrier, you may have to consider flashing to an earlier image.

[android-beginners] Re: Problem running the Hello World example
Finally it worked now. I am not sure why but it took like 10 mins.
I found a way to make it easy.
1. Use command line to run the emulator
emulator -avd avd_device_name to let it show the main menu.
2. Run Hello World by eclipse.
3. It will ask you to choose android device. Just select
"Choose a running Android device".
FYI
