Usually, I putExtra inside an Intent to transfer stuff between Activities. But it seems like I can't do this with a Service? Bundle extras = getIntent().getExtras(); That doesn't work for a android Service. How do I send a string from an Activity to a Service then?

does anyone know how to get result from subactivity to MainActivity without close the subactivity? i know the usual way is using method called "startActivityForResult (Intent intent, int requestCode)" and inside the subActivity set the result 1st before finish(); method
setResult(requestCode,intent); finish(); then the function called "protected void onActivityResult(int requestCode, int resultCode, Intent data)" which is inside main activity will get the result. BUT... by using that way, it will close my sub activity and the system will go back to main activity...........

I have just received my HTC desire, and setting up my email settings. I have three different email accounts, and set them all up. I set up the incoming server settings all fine, but when I put in the details for the outgoing server settings, and press NEXT button, I get the following each time: 'Cannot connect to the mail server to verify your account information. Your server is not responding.' This happens on all three accounts. I have used the same settings as on my computer which works when sending the emails on my computer. I finish the setting it up, but ofcourse I can receive emails, but can't send any.

I am currently trying to send some data from and Android application to a php server (both are controlled by me). There is alot of data collected on a form in the app, this is written to the database. This all works.
In my main code, firstly I create a JSONObject (I have cut it down here for this example):
JSONObject j = new JSONObject();
j.put("engineer", "me");
j.put("date", "today");
j.put("fuel", "full");
j.put("car", "mine");
j.put("distance", "miles");
Next I pass the object over for sending, and receive the response:
String url = "http://www.server.com/thisfile.php";................

I am developing an Android app that needs to communicate bi-directionally with a server. By that, I mean either the server or the device can send a message at any time, with an arbitrary amount of time in between messages. Sending data from the device to the server is a common and I think well understood task, but I'm not as sure what the best approach is to go in the opposite direction from the server to the device.
I think having the device periodically poll the server may be a bad idea due to latency and the drain on the battery, but I'd be willing to consider this option. My plan at the moment is to send text messages from the server via an email-to-SMS bridge, and to have my app run a service to receive and handle these messages.
The question I have is if there are any best practices for this scenario, and if using text messages has some downsides that I have failed to consider. For the sake of this question, I want to assume that users have an unlimited text data plan, so paying per text won't be an issue.

I'm writing an Android App and I'm looking for the fastest (In terms of setup) way for me to send data to a server and receive information back on request. We're talking basic stuff. I have a log file which tells me how a user is using my application (In beta, I wouldn't runin a user experience by constantly logging usually) and I want to communicate that to my server (That I haven't setup).
I don't need security, I don't need high throughput or concurrent connections (I have 3 phones to play with) but I do need to set it up fast! I remember back in the day that setting up XAMPP was particularly brainless, then maybe I could use PHP to send the file from the phone to the Server? The Server would ideally be able to respond to a GET which would allow me to send back some SQL statements which ultimately affect the UI. (It's meant to adapt the presented options depending on those most commonly used).
So there you have it, I used PHP about 4 years ago and will go down that route if it's the best but if there's some kind of new fangled port open closing binary streaming singing and dancing method that has superseeded that option I would love to know. This tutorial seems useful but I don't really need object serialization, just text files back and forth, compressed naturally. Android comes with the Apache HTTP Client 4.0 built in as well as java.net.URL and java.net.HttpUrlConnection, I'd rather not add too much bult to my App with third party libraries.

I have the localized strings file that is used in the Iphone app that I work on to port to Android. Are there any tools that go through the file taken from the xcode project and build the xml needed to use the strings in android? This tool should be easy to build but I appreciate any pointers to already working tools.

In Android, capturing date from datepicker and storing as string in sqlite. Sorting by date doesn't work because they're strings (unless I'm doing it wrong.I've googled this issue for ~5 days, and it looks like there should be a way to capture the date from the date picker, convert it to a Long, store it in sqlite as a Long, select and sort on the Long date value, then convert the Long back to a "mm/dd/yyyy" string for display. I've tried various combinations of parse statements, Date, FormatDate, etc. with no luck at all.On activity start, get today's date and display it in button which calls the datepicker.Capture new date from datepicker (if one is entered), save it as a long to sqlite.On opening an activity showing a listview of records, select from sqlite with orderby on date (Long), convert Long to "mm/dd/yyyy" string for display in ListView.

I know that this is not really an android question but i am new to both android and JSON. "Email":"g...@tkxel.com","Password":"123456"} to a url. The above structure is sent to Server in a variable named "json". The server reads the data and sends back the user information in a json object if the login is successful or {"error","-1"} if the authentication fails.................

I am running a Web service that allows users to record their trips (kind of like Google's MyTracks) as part of a larger app. The thing is that it is easy to pass data, including coords and other items, to the server when a user starts a trip or ends it. Being a newbie, I am not sure how to set up a background service that sends the location updates once every (pre-determined) period (min 3 minutes, max 1 hr) until the user flags the end of the trip, or until a preset amount of time elapses.
Once the trip is started from the phone, the server responds with a polling period for the phone to use as the interval between updates. This part works, in that I can display the response on the phone, and my server registers the user's action. Similarly, the trip is closed server-side upon the close trip request.........

Contact email *
Email address we should contact when you've been whitelisted:
aaa@gmail.com
Role account email *
Google Account ID that will be used for sending messages to C2DM:
bbb@gmail.com
I register from my app and sender id (bbb@gmail.com) to c2dm service and i get registration_id. After that my third party server must get ClientLogin authentication using email and password. From which email? The whitelisted email (aaa@gmail.com) or sender id (bbb@gmail.com)?? I try both email and from this process i got authorization_id. But when i use the registration_id and authorization_id to send message to C2DM Server, i got response codes 401 Unauthorize. I use authorization_id from whitelisted email (aaa@gmail.com) and sender id (bbb@gmail.com) but none worked.
