[android-beginners] XMPP service, Jabber
Hi, I am currently working on a project which requires a server to request data from the devices which are currently connected to the server. Meaning, first the server finds out which devices are connected to the server and then sends an application specific message to the client device which should wake certain functionality present on the client, like for example send out its current location. I was looking into XMPP service which looked promising since it works as a PUSH notification. The in XMPP can be used to check if the device is currently connected and has subscribed to the server. Since every android user has a gmail account, I was thinking of using the gmail xmpp service to connect /subscribe to the server. Then send specific message to the client, i.e x...@gmail.com. But if a message is sent this way the client app gets the message as well as the native gtalk client. So how do I go about intercepting this so that it doesn't show up on the gtalk client but my app still gets it. I want the PUSH notification to work, not PUSH. Please do comment on the above approach. If there is another way to do this, please do suggest. - SLY -- You received this message because you are subscribed to the Google Groups "Android Beginners" group. NEW!

Re: [android-beginners] Re: Android Emulator don't show up (Linux Fedora 12 x86_64)
Hello Indicator,
Of course this is true. I did this in anticipation of trouble and
afterwards found none. I'd still twiddle the permissions just for
safeties sake.

[android-beginners] Re: Is there a concept like DLL in Andoirds?
So the short answer to his original question, whether or not there is a 'DLL concept' in Android, is 'no'. If he really wants to, he can use the NDK as you suggest, but that sounds like a lot of custom work for trying to support a C/C++ paradigm in a Java world, an approach that is likely to offer more pain than profit. Android is based on Java, it is only to be expected that the Java way will be more natural.

[android-beginners] ImageView in ListActivity won't scale...
I posted this same question on StackOverflow two days ago and haven't received a response yet so I figured I would try my luck on here. For those interested here is the link to stackoverflow: http://stackoverflow.com/questions/2661223/imageview-scale-type-not-working-in-list-activity I have used ImageView's before and understand the different scale types that can be set... However I am having an incredibly difficult time trying to get an ImageView to scale properly in the row of a ListActivity or an ExpandableListActivity. I have tried setting the android:scaleType property to every single value but the image never scales down. I have set the min and max sizes as well and they don't seem to have any effect. I have done both of these things in both the XMl and in code to no avail... Does anyone have any ideas or perhaps a workaround? Here is the XML for my group row for an ExpandableListView: http://schemas.android.com/apk/res/android"; android:layout_width="fill_parent" android:layout_height="wrap_content" android:padding="6dip" > Thanks in advance for any help! -- You received this message because you are subscribed to the Google Groups "Android Beginners" group.

[android-beginners] Re: Android Emulator don't show up (Linux Fedora 12 x86_64)
I didn't have to follow that many steps to get it up and running. Yet
I am running under Fedora, too.
For example, 'yum' will allow wild-cards, so that where he ran many
yum commandlines, I needed only one. Nor do I remember having to
twiddle with permissions.
Then again, I am still running SDK v. 1.6. I never felt a compelling
need to jump to 2.1 when most phones are still running 1.5 or 1.6
binaries anyway. Until recently, it has been easier to find books and
websites documenting how to use SDK 1.6 anyway.

[android-beginners] Re: How often does an activity run?
It is most definitely not a "zombie process". A zombie process, by definition, is one not even the shell command 'kill' can kill. The process you just described is still able to receive events -- and will the next time the OS decides to call onDraw. It is Android that decides when to call onDraw(). However, you can tell it to do so by calling postInvalidate() or invalidate() as described in http://developer.android.com/guide/topics/graphics/index.html On Apr 18, 11:37 pm, BobG wrote: > If we run a simple little hello world program that just puts some text > in a textview, I see the the onCreate runs, and I guess it calls > ondraw once, then it sort of returns to the os, and if we have > registered a sensor changed or an onclick listener, we can read the > sensor and call invalidate and the os will call ondraw again, and it > all is usually 'fast enough'.

[android-beginners] Content provider example besides Contacts.
Hi there. I'm trying to develop a simple APN changer. I checked the tutorials and the CP are basicaly some sql databases accesed with a pointer. The thing is, for example, that the APN value seems to be in the settings DB? I dont find a clear reference to that in the API nor i can access it using the technique shown in the Contacts tutorial. Some lines of code to illustrate how to access the APN info me would be really apreciated! Sorry if this is terrible newbish, but cant find a simple non contact based tutorial regarding CPs. -- You received this message because you are subscribed to the Google Groups "Android Beginners" group.

In getView(), in the case where convertView is not null, you are calling
setImageURL(), then doing nothing with that value to actually load in
the replacement image.
Also, you are downloading the images on the main application thread.
That's going to be a problem -- your UI will freeze, and eventually
Android may kill it off with an "application not responding" error.
Please download your images off the main application thread, such as via
an AsyncTask.

Re: [android-beginners] Using Methods in a Service from an Activity
Ok, I've found the problem, for anyone else having trouble. In the tutorial, onBind() returns null, I created a MediaBinder class within MediaService, that implemented my MediaInterface, calling the relevant methods in MediaService. This works nicely. On 19/04/2010 21:43, Mark Murphy wrote: Tom F M White wrote: I'm calling start a relatively long time later, several seconds. Do I need to call onServiceConnected() myself? No, it should be called shortly after you call bindService(). This suggests that your bindService() call is failing for some reason (e.g., your service is not registered in your manifest).
