View 4 Replies View RelatedAndroid :: Inter Activity Communication In Tab Host Application
Jul 22, 2009Here's the deal: I have an Android application that needs to call a web service every X seconds (currently 60 seconds). This application has multiple tabs and these tabs all need to interact with the data themselves. One is a MapView, one is a ListView and then the third is irrelevant but will need to also get some global data eventually. The issue is that I want my main activity to have a thread that runs in the background, gets the results and then instructs both child activities in the TabHost to update themselves with the latest data. Also, when the user clicks on the tabs and the onCreate/onResume activities fire, I would also like to force a redraw by getting the latest data from the main activity. I'm really at a loss here. I've tried this with a service and some ghetto static methods to pass an instance of the Activities to the Service to call specific functions to update their views whenever the timer fired, but the slowdowns were pretty bad and the code was just ugly ugly ugly.
So I implemented it as a timer-driven thread in the tabhost activity and then I have timer-driven threads in each child activity that then grab the data (in a synchronized fashion) and update their map/list. It's much faster but still feels slightly hack-ish, especially the part where I'm calling a custom function in the parent activity like so:
((MainActivity)getParent()).getNearbyMatches();
This adds an element of strong coupling that I'm not entirely thrilled with, but from a performance standpoint it's much better than it was. I appreciate the answers that have already been given and will do a bit of research on the content provider front but I'm not sure I want to go back to the service model.

Nov 8, 2010I want to create an application that can be interactive with another Android device that could be across the room or across the country. For example, imagine playing Tic-Tac-Toe; but I'm the X's on my phone and the O's are my brother on his Android phone. I think it can be done via application specific messaging. Looking to see if it is possible, and, if so, how to send a message from one application to another on another device.

Mar 4, 2010I'm making an Android Java app game (although this question applies to all languages really) and hope to release the first version soon. I'm nervous about how I save data in my game. My problem is that, if in a later update, I decide to store more data or store the same data in a different way, I need to be careful I don't lose or corrupt data for users that upgrade (i.e. I want users to be able to use data created by an old version in the new version, like their high scores from before).For example, say I want to save high scores in version 1.

Mar 8, 2010I'm working on an undergraduate level senior design project with the HTC Sprint Hero. We want to connect a device that constantly sends a serial string of data. Does anyone have any hints, tricks, or shortcuts to be able to read a serial string from the USB port and save it on the phone? I know there is not a really simple way but I'm no where near an expert in programming and wanted to see if anyone has come across anything that might help.

Aug 18, 2010I used Eclipse with the Android SDK to develop the original application. I ask since this was my first Java (and Eclipse, and Android, and XML) project. I assume that most of the Java should run on the PC without too much trouble. I may want to restructure the code to isolate the Android specific functions. Should I stay with Eclipse or move to something like NetBeans?

Nov 7, 2009I'm the developer of 3G Watchdog, an application that monitors 3G traffic. I need help from Motorola Droid owners to port it to that phone.The app gets the network statistics data by reading pseudo-files /sys/ class/net/xxxx/statistics/rx_bytes and tx_bytes. "xxx" is the network interface name, which depends on the platform (or rather, the maker), e.g. for HTC phones it is "rmnet0", "pdp0" for Samsung..I'm looking for the name used by the Droid. If someone with a Droid could look (using adb) at / sys/ class/ net/ xxxx/ statistics/ rx_bytes and tell me what the xxxx is, it would make 3G Watchdog accessible to Motorola users.BTW, this remark is valid for any other future phone (Ericson, etc). New Android phones will appear on the market, and I need owner's contribution to port 3GW on them.

View 9 Replies View RelatedAndroid :: Advice On First Application (loading Data / Populating Data)
Jun 23, 2010to start with I've gone through the entire notepad tutorial, I'm a professional game programmer who has some extra time. (though most of my time has been in C++, I did take a year or two of Java classes in college, and remember some of it). I'm not sure the site is a good site to ask questions like this.. If someone has a Forum that might be a good place to ask these newbie questions, please feel free to point me in the direction. I've examined a few of the samples, and think I've a grasp of what I want to do. I've a three to four project plan for some Android releases to sharpen my skills, but since this is my first project and I have never really developed for a mobile phone or the android before, I'd like to make sure I have a solid plan.The first project is an example of the license plate game, however I want to do a few things to change it. Heck maybe when I'm done it'll become a bingo style game, with bluetooth connectivity, you never know. The base idea is I want to offer a list of states, with checkboxes next to them. so to do this, I'll be starting with a Linear List layout similar to the note pad example, and then have a row that is only a Checkbox. I can use text and call strike through if it's been checked off. Perhaps offer an option to not show them if they are checked.
But I want the list to be generated from a set of lists. Maybe all of America's states, maybe reasonable American states (no Hawaii, no Alaska) maybe a North American list, (add in Mexico and some Canadian provinces), a European list, who knows. I'd probably have to have a pop up window that lists all of the lists I suppose using a radiogroup of some sort. So then as far as the data, after weighing options I think best solution is to make a database with two fields, "checked" and "name".I figure I can use the menu for most of the user interaction (aside from clicking on stuff we want to check off) with maybe a few context menu items, I understand how to make all of those already so I should be good. The question I have is what is the best way to populate the lists? Should I create raw data, and have different files for all the lists? Or is there some other way to do this? I've seen this done on the searchable dictionary, but I'd like to hear what people who have actually generated the data like this before. In addition is there an easy way to look at the sql database these applications create, or do you have to run searches on them and output the data? Finally any other suggestion or advice? I definitely want to try to get something like this on the market so I can see the full life cycle and see if anyone actually likes it. (luckily there's not a plethora of them already) but I also want a few people to look over my code if they're willing when I'm done to make sure I've done this right or at least not missing any basic mistakes.

Dec 17, 2012I am new to android programming and I am trying to set a connection with the android as a host. I have included the following imports:

import android.hardware.usb.UsbManager;

My problem is when I use this code :m_usbManager = (UsbManager) getSystemService(Context.USB_SERVICE);The eclipse editor shows a message saying that getSystemService(String) is undefined for the type CPrinterCommands(The class that I am using). Quick fix gives as a solution to create a method called getSystemService, however I can't find why I would need to create a method, all the examples I found, none of them had a method getSystemService.
Android :: Communication With PC Client?
Dec 10, 2009I wrote a TCP socket client, an android application. On my emulator, it can successfully connect to a TCP sever running in my PC. But, when I deployed the the apk into my real phone, HTC g4, it dosen't work. An exception was raised said "java.net.SocketException: Network unreachable". The situation is, my handset was connected to my PC via USB, and no other connections were available. How can my android application connect to a PC server in the case. I don't know if we can use socket over usb connection. If yes, then why my application doesn't work. If no, then how?

Mar 30, 2010I have a design problem with my Android components.
My activity is starting a service which is doing the work in the background. What I want is that the service informs the activity about state changes. How can I do this?
Normally I would add an observer but the activity has no reference to the service. Then I was thinking to take AIDL but this is more for inter-process communication.
How is it possible that the service informs the activity about state changes? Both are running in the same process. What can you recommend?

Mar 19, 2009Just say I have two applications, each with one activity running on separate processes and I want to send a simple string between them. For the purposes of this example, let us say I have a button that sends whatever is typed into an EditText view to the other application where it is then displayed. Do I have to expose a remote interface via a service that co-resides between the two applications? Or can I do something simpler (is there a way to pass data between processes without defining your interface using AIDL)? Thanks for clearing this up for me, as I seem to be struggling with performing IPC at the moment. I'm pretty sure I have to use the Android IPC path and generate a remote interface using AIDL. I'm just not sure about the binding to service part.
View 7 Replies View RelatedAndroid :: Communication Between Droid Devices Over 3G?
Aug 25, 2009I'm not *entirely* sure this one is supposed to go here, but anyway :)
Assuming I have two Android-powered devices, connected both to the same 3G network; does the current API of Android allow to have a Service running on one of them being contacted by an Application running on the other one over this 3G network or do I have to go for a more traditional network (e.g. WiFi AP, Bluetooth) ? If so, how do I do it ?
I saw the usual Socket part in the API but it is not clear to me whether this is the way to use the 3G. I also found another discussion related to communication between a laptop and a dev phone ("Sending data to android dev phone using 3G connection") so it seems to be possible.
Does anyone have some details about how to do this?
