[android-developers] Samsung Galaxy S kill my app

Hello Boys and Girls!

 I had wrote an app which plays the backgournd music with MediaPlayer. I had tested the app, and it is works on Htc Desire perfectly, but when I try to test it on Samsung Galaxy S it dies with nullpointer exception on the following part: 

mp_bg_music.play();

Yes, I had used the Mediaplayer.create and as I said it work on Htc Desire! Any idea why not would my Samsung Galaxy S run the same program as HTC Desire ? Are there any additional thing what I should do before try to play the music ? Need more ueses-permission to app ? 

 Thank you so much: Károly from Hungary

[android-developers] Cursor in EditText not visible

Hi,

I am having a strange issue where the cursor in the EditText is not
visible but I can type and can do all stuff with the editText. The
scenario is I am giving background image to the editText and and
setting the textColor to white. The focus is there, then only we can
type.

I put cursorVisible="true" and tried with lot of trial and error
methods to make the cursor visible but of no use. From this I came to
know, if we can color the cursor other than the default color, it will
be better.

Anybody else have this issue earlier

Thanks

Re: Implementing a User Search Feature

If you just want a simple user search (which seems to be what you are
asking for), it really depends on your models - but a basic approach I
usually use is to define a django form to use for the search, and
instead of defining a save method, make a method that returns a
queryset. As an off the top of my head example for a django auth user
(untested, I might have screwed something up):

class UserSearchForm(forms.Form):
first_name__istartswith=forms.CharField(label="First name",
required=False)
last_name__istartswith=forms.CharField(label="Last name",
required=False)

def queryset(self):
from django.contrib.auth.models import User
filters={}
for k,v in self.cleaned_data.items():
val=v.strip()
if val: filters[k]=val
return User.objects.filter(**filters)

Then use it in your view like any other form:

def user_search(request):
usf=UserSearchForm(request.GET or
request.POST,prefix='usersearch')
users=usf.queryset()
return render_to_response('sometemplate.html',{'users':users})

Now if you really do want to do text indexing and have full text
search capabilities then you should look at the other suggestions.
For many things those are either overkill or too generic.

[android-developers] SurfaceView zooming

I have a SurfaceView which is used to play a video much like the MediaPlayer_video demo Java file

Plays I can Zoom In, but really this reduces the screen size and Zoom out will only to to the original max size in my case 1120 x 720

Because it is a SurfaceView I have had to use View.setScaleX and View.setScaleY and not use a matrix as I can't access the setImageMatrix

How can I zoom beyond the initial size, so I can truly zoom into an area of the video and watch it enlarged ?

Thanks in advance

[android-developers] Re: Is it possible to fix the orientation of a particular view in Honeycomb?

Yes. I do this all the time.

Let's say you have a vew "A"

layout:

Create a A-port layout, which is just a copy of the portrait oriented
A
Create a new A layout that <include> A-port

layout-land:

Create a A-land layout, which is just a copy of landscape oriented A
Create a new A layout that <include> A-land

layout-xlarge-v11 (or just layout-xlarge):

Create a new A layout that <include> A-land. It's a copy of the A
from layout-land

So, with this setup, on Honeycomb (or any XLARGE device, depending on
the folder you used), the layout used will always be layout-land. On
other devices, it will use the appropriately oriented layout.

Stay on a step in a form wizard until the user is ready to move on.

I'm working on a site that uses a form wizard as the main user interface. I've got one step however that I'd like to have a user be able to complete it several times if needed, storing the data bound to the user's session. Is there a way to do this using the FormWizard class, or am I asking too much? Thank you for your consideration and have a good day.

Since all requests must be handled by a Controller, you can simply bake your
business logic into the controller in question. For example:

load_and_authorize_resource # Be sure to specify who can create Users in
ability.rb

def create
user = User.create params[:user]
user.roles << current_user.roles # Or whatever floats your boat
end

[Rails] CanCan with Devise Invitable

Has anyone used this combination before? I am curious how I am going
to enforce my authorization rules beyond the view layer w/r/t
invitations.

Certain groups of users will be able to invite new users, but most
will not. When one group of users makes invitations, that magically
sets the role of the invited user to a particular group, and locks
that invited user into a Practice inherited from the person who
invited them.

Since the Devise Invitable controller lives in a gem, how can I reach
in there and extend it to be aware of these restrictions?

Thanks in advance,

Walter

[Rails] form_for routing issue

I defined a renew route for membership resources as following :

scope 'users' do
....
resources :memberships do
member do
post 'renew'
end
end
....
end

which leads to:
renew_membership POST (/:locale)/users/memberships/:id/
renew(.:format) {:action=>"renew", :controller=>"memberships"}

and in my view , my form helper is written as :
= form_for membership, :url => renew_membership_path(membership) do |
f|
...
generating the following HTML code :

<form accept-charset="UTF-8" action="/en_GB/users/memberships/1034/
renew" class="edit_membership" id="edit_membership_1034"
method="post">

<div style="margin:0;padding:0;display:inline">
<input name="utf8" type="hidden" value="✓">
<input name="_method" type="hidden" value="put">
<input name="authenticity_token" type="hidden" value="MDNH/
VmfJHBTgur3lksWEEuU5Rp02v70s8UFGR3hxG4="></div>

submitting the form, I get a routing error :

Started POST "/users/memberships/1034/renew" for 127.0.0.1 at

what could be wrong ?

Best way to disable a specific validation rule

I have a certain validation rule that I don't want to apply in one
particular cirumstance.
The rule is based on allowing a user to create something, if they are
the 'owner' of an assoicated model.

The rule works fine most of the time, but I want to override it for a
certain usertype. This user type has its own set of actions defined by
routes.

So, to disable the particular rule, I am doing this, in the action
'usertype_add'

unset($this->Model->validate['other_model_id']['userOwnsModel']);

Where userOwnsModel is a custom validation rule I have setup in the
model.

This seems to work fine, but feels a bit 'hacky'.

Is this an accepted soution in cakePHP, or are there any better ways
to handle this?

[android-developers] Flash player access camera

Earlier of the year, I found out that flash player can not access
camera and microphone in Android. So any cool flash site using camera
and microphone can't be used on Android devices.

Does anyone know when this will be available?

Thanks,
Kevin

[android-developers] calling services from broad cast receiver

Hi all

I need some help. In application,I need a service.
The scenario is like this, my application runs after a specied time
laps or interval as set by user through an alarm manager and do some
recording of GPS and store upto 10 location and send to the server.
But some time connection to server takes a long due to server
congestion and my application goes to ANR state. To avoid ANR I need a
service class for location updation to the server from broadcast
receiver and notify the completion of service to the broad cast
receiver when result is OK from the server.

Please suggest me how can I accomplish this task.
The main question is how to notify the broad cast reciver that service
has completed its task?

Thanks and regards
Sapna Srivastav

[android-developers] Re: AlarmManager - list of alarms set?

Hi Kostya.

This is basically a revival of this old thread, in which you helped me
some time ago.

http://groups.google.com/group/android-developers/browse_thread/thread/b2abad03be3467c0/d73f3780fbdd08f9

In my case, the onReceive method calls an ASyncTask which does some
network calls, so continues on for longer than the life of
onReceive(). I've implemented a Wakelock in my Receiver as you
suggested, which releases the lock once the network task has done its
stuff. However, the process *still* sometimes dies before it gets as
far as releasing the lock. It's definitely better now, just not 100%
reliable.

It's fine on 'good' phones, but on those with lower memory
capabilities (HTC Hero, Samsung Galaxy Europa for example) I still get
this problem. There's no errors, I'm sure of that, it's just being
killed before the task has completed.

[android-developers] AlarmManager - list of alarms set?

Hi all. I'm using AlarmManager to, well, set an alarm which then calls
a BroadcastReceiver at specified times.

Is there a way, in my code, I can get hold of a list of the alarms
that have been set, and then identify in some way if my alarm is in
the list?

(I want to do this because sometimes, the process dies in the
onReceive() method so the next alarm never gets set, and it would be
useful when the app is running to do a double check - and if it's not
in the list, then set it again).

Thanks.

[android-developers] Re: How to bind multi-layer Java class to JavaScript by using addJavascriptInterface() on WebView

Thanks Mark's reply.

Now I'm sure that I can't bind a "multi-layer" java class to
javascript by using addJavascriptInterface()

I got another plan : I create a js file to define and create the
"multi-layer" class and using java to create function only.
This is a sample:
====demo.js begin====
function AClass() {
this.B = new Object();
this.B.func = function() { return JavaA.func(); }
}
A = new AClass();
====demo.js.end====

====demo.html begin====
<html>
<head>
<script type="text/javascript" src="demo.js"></script>
</head>
<body>
<script type="text/javascript">
document.write("A.B.func1() return " + A.B.func());
</script>
</body>
</html>
====demo.html end====

====demo.java begin====
public class MyDemo extends Activity {
private WebView mWebView;
public void onCreate(Bundle savedInstanceState) {
...
mWebView = (WebView)findViewById(R.id.webView1);
mWebView.getSettings().setJavaScriptEnabled(true);
mWebView.addJavascriptInterface(new AClass(), "JavaA");
mWebView.loadUrl("file:///android_asset/demo.html");
}
final class AClass {
AClass() {}
public int func() { return 1; }
}
}
====demo.java end====

It could work fine.

But then I found another question: I'm trying to create an app to load
a Company's Web page. There are some self-define javascript class and
interface on the target page and I should let my app to support them.
I make a xxx.js to define all of them. The I aware I can't modify the
Web page's source document, so I can't add "<script type="text/
javascript" src="xxx.js"></script>" to the <head> block of html
document. That means I should add and excute my javascript define(such
as the "demo.js" below) after loadUrl().

Can anyone tell me which android interface could help me?
If there are any function to load javascript code after
WebView.loadUrl()?

Thank you!

[android-developers] Share Page

What I want to do is basically have an application run in the
background. So what the user would basically do is open the
application and then switch to a browser. After the User has opened up
the browser he would go on to clicking menu - more - share page and
would find the application name on the "To:" textfield. They would
then press send and then the application would redeem focus again and
the application would now have the url and it would proceed to do
whatever is needed.

My Question is how do I add a listener to the application and how do i
add the application name so you are able to see it into the "To:" so
when you press send the application would recieve the url and would
would do whatever the application needs. Can you guys please help me
out with this? I have looked at sever ways to go about doing this, the
most common "Intent Filter" but i am not able to see the name of the
application on the "To:".

Thanks in advance for the help.

I absolutely wouldn't assume that. As long as the API had existed on

Re: Comparing ManyToManyFields

You'll first have to explain what you mean by 'reading from a file'
and 'comparing'.

Are we comparing against serialized model exports? Is the user
importing data from a csv file? What column(s) is(are) you using as
keys for matching db objects against the file?

Give us a little more details and we'll try giving some suggestions in return =)

[Rails] How do you test for something in a certain area of the page with RSpec / Capybara? (view test)

I'm used to doing 

it "displays the controls link" do

  render

  rendered.should have_selector("a#controls")

end

..or using rendered.should have_content, but how would you test for something specifically in an area of the page?  e.g.

rendered.should have_content("Admin") in the "div#logo_area" or something?

I kind of wish there were many clear examples online...

You cannot "add some items in this context menu".

First, there is no context menu associated with your described
actions, at least on Android 2.3. There is a popup window that appears
when long-pressing on an MP3 file on my Nexus S.

Second, you cannot add items to a context menu in general. You might
be able to hook into select context menu items (e.g., implement
ACTION_SEND to show up in "Share" menu items).

[Rails] Beginner's question: Rails 3 and MySQL on Windows

Hello,
I've failed to get Rails 3 to connect to MySQL and have read that
the current MySQL ( which is MySQL2) doesn't work with Rails 3. It
isn't clear to me, from looking at the primarily *nix instructions on
the net, how to do this in Windows: settings in database.yml, gems to
install, where to get a MySQL database that works and where to put it,
etc. What are the proper steps?
Thanks,
Barney

[Google Maps API v2] Re: Need Delivery Area Help

How can this be accomplished?

one way I could think of would be to set up your delivery areas as
polygons on the map like this:
http://econym.org.uk/gmap/inside.htm

then geocode the address given and test which of the polygons contains
the address.

but there may be a better way.

[Google Maps API v2] Need Delivery Area Help

I have a google maps api key that I signed up for and need to define
a delivery area that will return results when a user types in their
address. For instance, if 30 stores deliver to users of my site but
all have delivery areas, I need a way to define their delivery areas
so when a user types in the address to be delivered to, only the
stores that deliver to that area will be displayed in the search
result. How can this be accomplished?

Can someone please assist me? I need to find a solution asap

Yes, it does say that you can't. See Term 9.1.1(b). Term 9.1.2 waives

I think that's what I said first time round; the Terms are quite
