I am trying to write a client application which talk to server application via bluetooth. Server application is running on embedded platfrom.
I referred bluetoothchat example for bluetooth data transfer. In my application I have two activities, Main activity shows list of bluetooth devices and when a user clicks on one of the devices it will open a new activity. Then it will open a bluetooth socket start thread to connect to server. I have a message handler which talks to the connected thread.
my codes looks like this
[HIGH]
public class ConnectActivity extends Activity {
// Unique UUID for this application
public static final UUID MY_UUID_INSECURE =
[Code]....
Some times my UI hangs when I click a button, it takes ages to respond back. In my method for ledOn I call bluetooth input stream. Is this correct method to do it.

I've built my first Android application and it works pretty well, except that it hangs/freezes up when it's left running for several hours.
It doesn't always do this - it's inconsistent.
This is an awful question to ask, it's so broad, but how should I go about troubleshooting this problem?
My guess is that I'm not managing my exceptions well and something's happening that I'm not dealing with effectively.
Is there a good resource of information on testing and debugging Android/Java applications like a Web site or a book?
I'm just looking for someone to shove me in the right direction.

I was able to instantiate ObjectInputStream but now my program hangs at .readObject() I am making an android app in which I want to transfer file from my server pc to my android phone. The server reads the file , encapsulates it into a bytearray and then writes it as an object of a class to the ObjectOutputStream. Below are the code snippets from the andriod appication client side.This is the class whose object is to be send
Code:
import java.io.Serializable;
public class FileClass implements Serializable{
public byte file[];
public FileClass(byte file[])[code].....

Do I have to sign my application before submitting it for ADC II? Is yes, how do I do that? Do I have to buy some certificate?

From the signing documentation at http://developer.android.com/intl/zh-TW/guide/publishing/app-signing.html:
When the system is installing an update to an application, if any of the certificates in the new version match any of the certificates in the old version, then the system allows the update.
This indicates that an application can be signed with multiple certificates.
This is an interesting option to allow multiple entities to sign an application. e.g: A system application which was initially signed by the device's manufacturer. Further updates could be signed by the developer.
Am I misreading the documentation or is this really possible? If so, how?
Is there any other way for an application to support different certificates and with that, having two or more entities sign it?

I'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.

I have already submitted/published an app on the Android Market. I had the strings.xml file translated into other languages, and now I'd like to publish the different versions in that language. I cannot help but get the impression that by doing so, I will erase the original (in English) version.I think because the package name is the same throughout the entire product that the Android Market sees it as the same APP and will overwrite any previous apps.How do I publish an APP (APK) file that has just been translated or localized for a different language? What is the procedure? Do I have to go in the code and change the entire code ? or is there another way?

I'm heading to Halifax, Nova Scotia for a week and will be bringing my Hero with me. I'll be calling Sprint customer support to see what options are available for voice and data, but I trust the advice of folks in this forum.
Is there any international voice and data plan that i can sign up for so that I don't end up paying sky-high roaming rates? I really don't want to have to keep my phone in airplane mode the whole week. Any advice from travelers to the "Great White North" would really be appreciated, eh?

I have a theme I've made for my iPod touch a while back ago, I want to update it and put it on the playstore for use with Nova and other launchers/themers.how do I make an APK file out of the Icons? (im on mac if that matters)
How does google play work if I was to charge for themes? Do I need a paypal or does the payments go on to my credit/debit card directly from google?If I was to make my icons HD size do the launchers resize them or i need to make SD size too?

to 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.

I have to draw list of 30 articles. I tired using list view but there was some problem as I wanted to user alternate colors like first is white and 2nd is blue where as again 3rd is white and 4th is blue and it goes on..
So I decided to have scrollview and table into it. I set the view using setcontentview which shows loading dialog. then in aysnc task's "doInBackground" method i fetch all articles into the object and then in "onPostExecute" I run a for loop on the object and in each loop i make table row insert article and then insert row into table. and then dismiss loading dialog box.
As i have tabular view in my app and If i remove loading dialog box. While the UI is rendered if someone clicks on other tab. UI is hanged up, After loading all table rows It goes to other tab.
Even after using asynctask why this happens ?

I'm using a Drioid Eris version 2.1. When I turn on my phone it stays on the starting screen (the androids on skateboards) and won't go to the next one. I think it may have happened after I updated my SD Card Reader app because that's the only thing I can think of that caused this problem, thought it might be something else. How do I fix this?

I've been trying to upload an APK file to the Android Market for a few days, and the upload process hangs with the spinning icon just rotating. I've let the upload run overnight and it still hangs.
1) The APK file is 28 MB
2) I've uploaded an APK file to the Android market before and it is now for sale.
Is there a way to find out what the error is?

Anyone having problems. I tried in the browser and it hangs as well, so not convinced it is my use of the MediaPlayer, which hangs passing it a 320 kpbs mp3.

I am giving product build in Android 1.6 in Ubuntu using make. First time it is fine. But next time onwards if I try to build it again without cleaning it, the system hangs after some time. Even if I try remove the out folder to clean, the system hangs. So every time a fresh build takes too much time. Did anyone face this issue? I am using 1 GB RAM, 1 GB swap space and 40 GB linux space(65% space is free).
