Android :: Multiple Calls To SimpleCursorAdapater That Has A ViewBinder
Jul 30, 2010
I have a ListView populated using a SimpleCursorAdapter that has a ViewBinder, and I'm finding that when the ListView is displayed, ViewBinder#setViewValue is called 3 times for each row of the cursor.
CODE:................
And the third time from onMeasure again.
Firstly, is this expected behaviour?
If it is, then what's the best way of performing potentially expensive work in ViewBinder#setViewValue? For example, retrieving the results of another cursor whcih is used to construct the bound view.
Or am I approaching this from entirely the wrong view point?

I am using setViewValue method of ShowViewBinder to access image inside row of listView. The idea is to load image from internet and display it inside row of listView.
To load image, I am starting new image loader thread, but what I discovered when debugging this code, for each row I am actually starting 3 or 4 threads. I don't understand why. The code in if (columnIndex == ...) is executing more than once.
My code goes something like this:
CODE:...................

I've been hunting for a solution for days and can't find an answer. I've got an application where I need to place multiple calls in a row. I can invoke the dialer just fine and it starts calling the number. The problem is that after the call is over the call log comes up. I don't want the call log to come up. I want the dialer to return to my application after the call is over. How can I do this?

I have a ListView with custom ArrayAdapter. Each of the row in this ListView has an icon and some text. These icons are downloaded in background,cached and then using a callback, substituted in their respective ImageViews. The logic to get a thumbnail from cache or download is triggered every time getView() runs.

Are there design guidelines to help decide if an application with multiple views should be designed with multiple activities or just one activity and control the back button itself.
I've tried both. My most complex applications using one activity per screen. However, now that I'm successfully written an app with just one activity and handling the back button myself, I don't see any compelling reason to use multiple activities. The one activity application is much simpler and more straightforward.
What advantages of multiple activities am I missing?

I'm working on an application using xml layouts.
I wish to know which is better:
1. Use few activities and change its contentview
2. Use an activity for each 'view' needed
If both works, in which case which option would be better?

I'm planning to develop and app that presents the users with several different screens (of different information).
Was wondering what would be the best way to implement this?
Is it better to have separate XML layouts and an activity to display and allow the user to interact with each screen of data?
OR would handling all of these in the same activity be more efficient (and dynamically load / unload each layout)?

Not sure if this is technically the "silent bug" but calls do not even show up on the phone, they just appear as "missed call from...." no noise no other notification. I restarted phone but it did it again right away. Phone does show the 50% bug in battery info.

Is there anyway to make VoIP calls or Skype Out calls on the EVO? I am switching from the iPhone 3GS and am going out of the country on vacation in a month and I got used to making Skype Out calls over WiFi when out of the country.

having problems receiving calls. When I call the phone from another line, nothing happens except its logged as a missed call. The screen doesnt light up and no options for receiving calls. This happened before I installed Google voice. I disabled Google voice and still no joy. Everything else works. I can make calls, browse over WiFi and 3G.

I've been doing my research on the subject but I have time believing that there is no services that will allow me to me 3G calls with my Nexus One (it is my understanding that with the iPhone there are several services that offer that). Is that true??? I'm in Canada so the Google Voice service is not an option.

I would like to know whether its possible to record call in Android. If its possible then which class should be used for that purpose. I think there should be some message broadcast receiver invoked when a call is accepted and application should be started in background and record the conversation. Would like to know if this is actually possible and it it is then what classes to refer to?
One more thing if I want to send the recorded file to a server through GPRS then is there any limit in size for it to get transfer through GPRS? Small files will be transferred easily through GPRS but what about larger files? Is there any upper limit as to files of this much size can be transferred.
More importantly I want to know about the call recording function. Whether its available in Android phones as a native applicatoins or not? If its not available then can a application be written that can record all incoming and if possible outgoing calls as well.

Is there a blacklist app that allows me to simply reject (either by picking up and hanging up, or by saying the number is disconnected) numbers that I specify. I used an app called iblacklist on my iphone and it works wonders for this. I was wondering if there is something in the market that functions the same as this. iblacklist also removes the calls from the recent calls list, that would be useful but not very important.

Does anyone know of an app (for hero) that would allow me to make and receive calls on my desktop when my phone is plugged in via usb? I have desktopSMS going and was wondering if there is something similar for calls. I have unlimited voice/text so i don't need anything to avoid that, my problem is that where i sit in the office i can't get a signal on the phone, but plugged in via usb my phone can sit on the window sill and get reception so it would be handy not to have to run across the room every time it rings! i tried searching the forums for this but on and pc are too short to search so you can imagine how many hits for "receive calls" there were!

I have been trying to develop an android application for sometime now and i would like to get some suggestion on the best way of making web service calls or to be generic the best way of communication between the android platform and web server. Soap(using Ksoap) and HTTP(using POST) are two methodologies & XML and JSON are the two data formats that am aware of,(let me know if they are few other options too..) and , i would like to know what is the best option of data transfer when i) the data to transfer is Large and less frequent. ii) more frequent but less data is being transfered. Also when it comes to data synchronization between server and our app , how is that generally implemented?

How can I publish two versions of my app without changing the package name, so that users may upgrade to either version, one for Anroid 1.5 and one for Android 1.6 ? I want to offer new features requiring Android 1.6 as soon as possible, but not all users will have upgraded to Android 1.6.

I am picturing something like what I saw on G4 a year or so ago. Program that takes multiple pictures and creates a 3d map based on them in which you can walk around inside the map. I really wish I still had the bookmark for that page. Anyway, is that the same as what you are talking about here? Or am I mistaken? If it is the same, it is an amazing concept. I look forward to the site being up and running so I can poke around a bit. (Right now, it won't connect).

I am including a class in my app that another developer has made freely available. His class has a different package. Will this cause any issues on Android, the market, etc? Does every single class in the app need to be my own package?
