Re: [android-beginners] Animation tutorial

[Marc Young]

There is a free app in the marketplace called Animation Demo and it
gives you a visual demo of how and what the various animation
parameters work.  Not sure if that will help you at all but it is a
good starting point.

[android-beginners] Layout - Is there some way to do wraparound with horizontal linear layout

[Marc]

I have been trying to create layouts that will work on various device
screen sizes. I keep running in to cases where I want to line things
up horizontally and have them wrap around if the screen is not wide
enough.

For example in landscape mode I might have
() Radio Button 1 () Radio Button 2 () Radio Button 3 ()
Radio Button 4() Radio Button 5   () Radio Button 6

but in portrait I would have
() Radio Button 1 () Radio Button 2 () Radio Button 3
() Radio Button 4() Radio Button 5   () Radio Button 6


I have the same issues with text view and edit text combinations
for a wide screen I would like
TextViewEditText

for a narrow screen I would like
TextView
EditText

It seems like there should be some way of getting views to wrap around
to a new line if there is no room, just like a text string does.

I know I can have separate layouts for different screen sizes. I am
hoping to find something more elegant.

Thanks.

[android-beginners] Getting Published - Do I need a website - Market requirements? Publish as com.example? new namespace?

[Marc]

I am finishing up my first app now and was wanting to get it on the
market. I went to sign up and it was asking me for a website url. I am
not cleat on this requirement. Do I need to register a domain name to
publish and android app? Or maybe can I use a free web site by google
or something. Also my app is still under com.example, It seems like I
would need to change this to publish and it seems related but I am
unclear on this aspect. Could somebody explain to me the requirements
for being published, related to namespace and a web site?

Thank You.

[android-beginners] importing nbandroid into netbeans

[Marc Mrc]

I am new to this. I have downloaded the Android SDK and the android platform
components up to 2.0.1,  Java Netbeans IDE 6.7.1 and can't seem to find
where to pull the nbandroid files into it? I have not used netbeans before
and I am learning, when I open a "new project" I don't see it listed in the
project category, nor do I see it listed under tools. plug-ins. How do I
point the file so netbeans imports it or sees it?

Thanks,

[android-beginners] Re: Android Best Practices

[Marc]

Here is my take on it:
An activity is a self contained thing, like a mini program. You don't
pass complex data structures between activities. All the data that
goes to/from an Activity gets passes through an intent. An activity
can be called from another program through an intent. So an activity
is a self contained thing and a View is just something you can see.

If 2 pieces of a program are very tightly bound in that they share
some internal data and/or each part of the program can not logically
be instantiated by itself then it is not a new activity just a new
view.

Examples:
A database of car maintaince records might have a few reports that it
displays and a "enter a new record" screen. In this case the "enter
new record" screen and the reports could in theory get instantiated
outside the context of the rest of the program and therefore would be
a good candidate for separate activities.

A 3d modeling/editing program that lets you open windows that allow
you to edit some of the 3d model data. Since the 3d model data is kept
in memory and the edit screen is only editing a small piece of it, and
the edit screen makes no sense outside the context model screen. This
would be best done with separate views.

This thing of having your program broken up in to mini programs
(activities) that are callable by other programs is really new to me,
but the more i understand it the more I realize it is a really
powerful thing to be able to integrate parts of other programs in to
my own.

[android-beginners] Re: Using Google Maps API for a navigational app

[Marc]

I am in the process of starting a navigation app as well.  I have been
looking in to the API's as well. I do not think the premier has much
to do with it. From there web site this is what premier gives you
extra:

A robust Service Level Agreement (SLA)
Customer support
Increased geocoding limits
Commercial-grade terms and conditions
Intranet application support within the enterprise
Access to the API via a secure https connection

I have not found any navigation api's. I was hoping to find an api
that would return driving directions between 2 spots. But I found no
such api. I am thinking that it needs to be done with a combination of
accessing web pages and parsing them, the static maps api, and intents
in to the google nav app.

[android-beginners] Debugging in to android SDK code, or some other way of determining why it crashed

[Marc]

I have a subclass of AutoCompleteTextView which displays the list of
suggestions when a touch event happens.  I get a Null Pointer
Exception which I am at a loss as to how to debug.

Thread [<3> main] (Suspended (exception NullPointerException))
DataSetObservable.notifyInvalidated() line: 45
ArrayAdapter(BaseAdapter).notifyDataSetInvalidated() line: 54
ArrayAdapter$ArrayFilter.publishResults(CharSequence, Filter
$FilterResults) line: 464
Filter$ResultsHandler.handleMessage(Message) line: 263
Filter$ResultsHandler(Handler).dispatchMessage(Message) line: 99
Looper.loop() line: 123
ActivityThread.main(String[]) line: 3948
Method.invokeNative(Object, Object[], Class, Class[], Class, int,
boolean) line: not available [native method]
Method.invoke(Object, Object...) line: 521
ZygoteInit$MethodAndArgsCaller.run() line: 782
ZygoteInit.main(String[]) line: 540
NativeStart.main(String[]) line: not available [native method]


It seems like if I could step in to the Android SDK source code I
could see exactly what is going on and come up with a workaround.
Right now I have no idea what is actually going wrong. Any suggestions
as to how to debug this.

There is not much to my code, this is all I have done, It does not
crash when I remove the call to showDropDown():

class SuggestText extends AutoCompleteTextView {
int cnt=0;
public SuggestText(Context context, AttributeSet attrs) {
super(context, attrs);
}

public boolean onTouchEvent(MotionEvent event){
if (this.isFocused() && 
getEditableText().toString().length()==0) {
showDropDown();
}
return super.onTouchEvent(event);
}
}

Re: [android-beginners] Cannot get MSISDN (phone number) but can get IMSI on HTC G3

I think some carriers don't provide the MSISDN to the handset so I guess you
shouldn't rely on it. Just use the IMSI and device id to identify the user.

[android-beginners] Re: alarm manager confusion

[marc]

jeffrey, how did you solve the problem?
i made a own process for the broadcastreceiver (as said in the linked
theme), so i have 2 processes now:
cycle:
1. user starts application
2. user schedules the alarm in the application

current processes:
- application

3. scheduled alarm expires, broadcastreceiver will be started
4. broadcastreceiver execute his work and SCHEDULES A NEW ALARM

current processes:
- application
- broadcastreceiver

5. scheduled alarm expires, broadcastreceiver will be started
6. broadcastreceiver execute his work and SCHEDULES A NEW ALARM


if i kill the application after step 2, the scheduled alarm survives.
if i kill the alarm after step 4. the scheduled alarm is lost, step
5/6 will not be executed.

how did you do it?!

thank you for a answer.

[android-beginners] Re: Creating reflection of a view

[Marc Poppleton]

Hi,

Maybe this tutorial would be a good start:
http://www.brighthub.com/mobile/google-android/articles/30676.aspx

Once you have a bitmap, you just have to flip it, add a gradient mask,
eventually blur it a little to give a little more natural look to the
reflexion, and you're done.

Thanks Dave. Although when I tried putting 100 in the setVolume method

clickSound.setVolume(100, 100);

The volume level in the emulator seems to be louder when compared to 1.0.
Any idea?

Hi folks,

I just want to ask if somebody knows the usable range for the MediaPLayer's
volume levels? The doc just says it is a raw scalar and the UI should scale
logarithmically. An example would be helpful.

Thanks in advance.

[android-beginners] Re: Soap Xml parsing

Hi,

I'm still new with android but hopefully this snippet will help you:

Let's say you have your Service class:

  public class Service{

then you can use DOM parser to parse your xml:

> List services = parseDocument(dom);

My application needs to display CR LF (new line) on the TextView. Currently

that the TextView doesn't display CR LF characters property. Any idea on how
to fix this?

I'm still learning a lot from the tutorials and sample codes. But could
anyone give some example on how to display an Image with a given URL (for
example, link from a flickr). I'm actually planning to create a gallery
pulled from an RSS feed.

Thanks in advance.

[android-beginners] Re: Map problem on Vista

[Marc]

I must be losing it.  It's just started working, and I'm absolutely
positive NOTHING has changed.  Oh well.

[android-beginners] Map problem on Vista

[Marc]

I'm desperately in need of some help.

I can't get the maps app to work on the emulator.  I can successfully
use the web browser to view any webpage I want (so I know it's not a
network issue), but whenever I load the maps screen I just get a
chequered grey screen and no map.  After awhile I get a message "Oops!
The network seems to be down for now. We'll keep trying, though."

I'm running the emulator under Windows Vista.  When I try the emulator
under a WinXP virtual machine, everything works fine.

Below is the output from the emulator when I run it with the "-logcat
debug" option.

Thanks in advance.

[android-beginners] Re: cant find a popupwindow tutorial

[Marc]

If you are looking for alert dialog boxes,  refer
http://www.handandaily.com/android/docs/kb/commontasks.html#opennewscreen

There is a nice sample coming with android sdk in android-sdk_m5-
rc15_windows\samples\ApiDemos\src\com\google\android\samples\app
\AlertDialogSamples.java

regards,
Marc

[android-beginners] Use AlertDialog inside a service.

[Marc]

HI All,

Is it possible to use an AlertDialog as a notification instead of
using a Toast?? My requirement is to display a text notification,
which is not disappear in few moments. User should be able to close it
by pressing the return button. Please shed some light on me.

Thanks in advance

Marc
