[android-beginners] Re: Cannot create AVD in window XP
This is because the Android HelloWorld example: http://developer.android.com/guide/tutorials/hello-world.html ...points to the download page of the 1.1 SDK, whereas you need the 1.5 SDK to be able to use the 'android' command from the same example!

[android-beginners] Re: Cannot create AVD in window XP
I have the same problem as this. There is no 'android' executable in the tools directory - should there be? I only have an android.jar file in the tools' parent folder, but this is not part of my path, and I'm not sure if this is what is meant to be running.

I had this installed on my ADP for weeks and it was working great until a few days ago, and then all it was doing was displaying the same error message you are getting.

[android-beginners] Re: Is learning Java directly on the Android possible or a good idea?
I agree with the others that you should learn some Java on the PC before diving into Android. Everything you need is in the JDK and Notepad. After that, you might find you need to go back and look up a few things that are not so basic. Depends on how far you go with Android, but just reading through their samples in the SDK you will need to understand interfaces, generics, and constructors. Head First Java is a good book however it might be a little long if you are anxious to get going with Android. Take a look at Java Demystified which is much shorter and also very good. Good luck!

[android-beginners] Re: How to redraw the list in ExpandableListViewActivity
I've got a very similar app I'm doing now, I replied to your other
post as well, just to point out that I'm also using onActivityResult
however instead of invalidate I just force the activity to launch
again. I track which tab they were on before they launched the
activity which created the new record so when it comes back to this, I
know which tab to set it to with the setCurrentTab. It sounds really
inefficient (and it is) but so far with some big lists I am getting
really good results. And of course, you've already got it where you
don't redraw when there was nothing edited or created.

[android-beginners] Re: TabHost problem with designing Tabs
Have you tried using a TabActivity, then you don't have to use a layout XML file for the tabhost. Each tab calls its own intent, and that activity can use its own layout file. Not sure if that fixes your exact issue, but then you won't have to worry that you are messing up your overall layout of the tabs, or the other tab. You can focus just on the one tab that is giving you trouble. On Aug 17, 2:44 am, Stefan wrote: > Hi, now I have a new problem.

[android-beginners] problem with Hello, Gallery R.styleable not resolve
I've been working through the Hello,Views examples. They are great
resource - thanks to those that created them.
There is a problem with the setiton on the example using
android.R.sytleable
public ImageAdapter(Context c) {
mContext = c;
TypedArray a = obtainStyledAttributes
(android.R.styleable.Theme);
mGalleryItemBackground = a.getResourceId(
android.R.styleable.Theme_galleryItemBackground, 0);
a.recycle();
}
Eclipse reports that R.styleable cannot be resolved
There are lots of messages on the web about the problem. Finally I
found one that reported android.R.styleable. is no longer supported in
sdk 1.5
http://mac.softpedia.com/progChangelog/Google-Android-SDK-Changelog-31208.html
If this is officially true, it would really be helpful to people
trying to learn Android programming to have some official notification
in the example and a revised workaround approach. Otherwise a lot of
people will be wasting a lot of time.
thanks

[android-beginners] Installing the SDK alongside Amazon EC2 Tools on Mac
Hello,
I recently went to install the Android SDK and noticed a potential
problem.
I have the amazon ec2 tools installed and it uses a the PATH variable
in ~/.bash_profile
the line i have for ec2 tools is: "export PATH=$PATH:$EC2_HOME/bin"
the android sdk wants me to add "export PATH=${PATH}:/
tools" to ~/.bash_profile
i was wondering is there was anyway to use a different variable so i
can have both at the same time or will i have to do what im doing now
and comment out one of the lines to use the other.
thanks in advance

[android-beginners] Re: Creating a Lite and Pro version of an application
I don't think the other thread explained how to do this without creating two package names. You would either have to re-name your package each time you published, or you would need two different projects, wouldn't you? Another approach is to try to pull out as much common functionality as you can into a 3rd Java-only project, with each of your projects (paid and free). The tough part is that you can't move anything that references resources into a Java-only project.

[android-beginners] Exif intrerface not found
Greetings, I'm on a HTC Tattoo (Android 1.6) and am trying to use the exif interface. However it does not appear to be visible. Am I right in assuming this should be available? Also I'd be interested in hearing what way poeple here have been getting exif information from photos.

[android-beginners] Re: Hello Date Picker
I am also working through this example but ran into a different problem. The lines: mDateDisplay = (TextView) findViewById(R.id.dateDisplay); mPickDate = (Button) findViewById(R.id.pickDate); give the error "R.id can not be resolved". R is never declared anywhere. What is it supposed to be?

Any suggestions on what I'm missing here?

[android-beginners] Re: "Corrupt XML binary file" error when adding a PNG to res/drawable
Hi,
The file is res/drawable/androidmarker.png (taken from a tutorial).
I'm not referring to it at all; I'm merely placing it in the drawable
directory. Removing it removes the error.
Thanks,
Steve

[android-beginners] Re: How to redraw the list in ExpandableListViewActivity
Hi,
I posted this on another forum it might be of help and you might be
able to answer questions!!
Very pleased :) with the way ExpandableListView works but am unclear
how to set the clicked view as invalid.
In the onChildClick(ExpandableListView parent, View v, int
groupPosition, int childPosition, long id)
{
I call the Dialog "Enter" and wait for dismiss so:-
Value = new Value_Input(test2.this,0, custno, itemno, day);
Value.show();
Value.setOnDismissListener(new OnDismissListener() {
public void onDismiss(DialogInterface arg0) {
getExpandableListView().invalidateViews();
}
});
}
the invalidateViews() seems a bit heavyweight when I only want to
redraw the clicked view.
(it also has side effects (mine) which I want to avoid. ) :(
the other options are:-
getExpandableListView().invalidate();
getExpandableListView().invalidate(dirty);
getExpandableListView().invalidate(l, t, r, b)
getExpandableListView().invalidateChild(child, dirty)
getExpandableListView().invalidateChildInParent(location, dirty)
getExpandableListView().invalidateDrawable(drawable)
basically how do I get from groupPosition, childPosition to the View
after the event??
or how to use one of the above??
any suggestions would gratefully received!!
Steve
Alas there is more - I have a command to expand the group and move it
to the top of the display:-
case 1:// "Move to Top")
getExpandableListView().setSelectedGroup(groupPosition);
getExpandableListView().expandGroup(groupPosition);
getExpandableListView().invalidateViews();
break;
This does not cause the children to be redrawn indeed there is no
subsequent call to getChildrenCount(int groupPosition)
getExpandableListView().setSelectedGroup(groupPosition); <- I was
hoping this might move group to top of screen!

[android-beginners] Two Problems with ExpandableListView
Very pleased :) with the way ExpandableListView works but am unclear

Problem One

What I need is:-

How do I get the adapter not to draw GONE views. I have tried the
trick I used in the simple BaseAdapter in both getGroupView and
getChildView but it does not work :-

[android-beginners] Help Needed with Opening File
Hi,
I am relatiely new to both java and Android.
I assume that files opened in "user.dir" are held in fast battery
backed ram" and that /sdcard/ is a slower rom device.
I am attempting to copy a file of about 450k from the sdcard to the
"user.dir" so that I can have much faster reading/wrting of the file.
CopyfiletoMemory(..) works fine but the subsequent call to open the
file as a
RandomAccessFile in Openfile fails with FileNotFoundException?? any
ideas
public void CopyfiletoMemory(String filename){
try{
FileInputStream in = new FileInputStream("/sdcard/"+filename);
File temp = File.createTempFile("/"+filename, null );
FileOutputStream out = new FileOutputStream(temp);
// Transfer bytes from in to out
byte[] buf = new byte[1024];
int len;
while ((len = in.read(buf)) > 0) {
out.write(buf, 0, len);
}
out.flush();
in.close();
out.close();
System.out.println("File Copied");
}
catch (Exception e){
System.err.println("File input error");
}
}
public void Openfile(String filename){
try{
String destination = System.getProperty("user.dir")+
filename;
File fileCon = new File(destination);
fstream = new RandomAccessFile(fileCon.getPath
(),"rw");
ReadRoundData();
customer = new t_customer();

[android-beginners] Re: Help Needed with Opening File
I eventually solved the problem with help of following dicussion
http://www.anddev.org/viewtopic.php?p=25297#25297
my solution is:-
public void CopyfiletoMemory(String filename){
FileOutputStream fos;
DataOutputStream out;
try{
FileInputStream in = new FileInputStream("/
sdcard/"+filename);
boolean success = new File("/data/data/com.example.test2/
data").mkdir();
if (!success)
System.out.println( "no success");
File file = new File("/data/data/com.example.test2/
data/"+filename);
file.createNewFile();
if(!file.exists()){
file.createNewFile();
System.out.println( "File created...");
}
fos = new FileOutputStream(file);
out=new DataOutputStream(fos);
// Transfer bytes from in to out
byte[] buf = new byte[1024];
int len;
while ((len = in.read(buf)) > 0) {
out.write(buf, 0, len);
}
out.flush();
in.close();
out.close();
listfiles();
System.out.println("File Copied");

[android-beginners] Using ExpandableListView inside a Dialog
Hi,
I am new to Android and Java. The answer is not obvious (to me)
I have been using ExpandableListView inside an activity quite happily.
so...
public class PaymentList extends ExpandableListActivity{
ExpandableListAdapter mAdapter;
...
mAdapter = new MyExpandableListAdapter();
setListAdapter(mAdapter);
registerForContextMenu(getExpandableListView());
...etc
I now want PaymentList to be a Dialog so:-
public class PaymentList extends Dialog{
cannot resolve "setListAdapter" or "getExpandableListView".
How do I get over this (provide the getExpandableListView
functionality inside the Dialog) ???
Steve

[android-beginners] Re: Using ExpandableListView inside a Dialog
Thanks for the prompt reply but the complexity of defining
ContextMenus and setting up the GetViews associated with the
ExpandableList within a Custom Dialog are currently beyond me.
However I have got
Intent i = new Intent(GetFlagSet.this, PaymentList.class);
startActivityForResult(i, 0);
working so I can put back the time when I need to crack creating a
more complex Custom Dialog.
Many thanks Steve

[android-beginners] ExpandableList Items click after scroll
Hi, I am working on an ExpandableListView. It all works fine until I scroll the current set of views off the screen where upon I cannot select either Groups or Children. After trying to select a group when I roll the ball the group I tried to select becomes sellected and all views within the created view set become selectable.

[android-beginners] Unable to see Google Map - but eveything else seems to be working....
I have an odd problem. I'm working on my first Maps application. I'm using the demo/tutorial code as a baseline to figure this out. I have the app running, I can see the zoom controlsbut no map graphic. I see no errors in the console. I've set the debug.keystore. I also have the key for the API set. I've verified I have them in the right place according to the Eclipse configuration. I can even add an overlay with a small graphic with no problem. But I still only see the "graph paper"-like background for the map. I'm not sure what's going on. Using Java 1.6. Anybody have any ideas? Thanks!

[android-beginners] Is it necessary to rebuild android platform
I've setup my development enviroment on Windows with Eclipse and the ADT plugin and and build and run the Lunar Lander sample. I'd like to be able to build the Android Mail application but it's using a newer version of the framework (for example, it's trying to import #) One solution is to rebuild the latest Android platform using the latest source from GIT. That would mean installing Linux on a VM on my Windows machine and rebuilding it though, and I can't be bothered. Is it possible to get the ready-built files (including android.jar for example) without building from source ?

[android-beginners] Re: Hello Android!
Go into 'Run Configurations' and hit the 'Target' tab. Change the 'Emulator Launch Parameters to GPRS for Network speed and Latency. You could also tick the 'Wipe User Data' tab. Then all you have to do is run the app and give the emulator time to boot up (although you can disable the boot animation too). Don't know about the other question; I'm a beginner too and the Notepad app tutorial looks pretty scary!!
