Was just wondering if anyone had any code samples about writing and retrieving data from a website? I am currently creating an application which populates its textviews by accessing information from an online source.

I once got pointed in the direction of this great set of examples:
http://code.google.com/p/apps-for-android/
These samples look like they're in some way connected with this forum. Is that the case?
There's one app in particular which I would like to discuss with the developers, the 'SpriteMethodTest' app, as I have adapted this for my own use and have some issues.
Anyone know anything about these apps?
Does anyone have any working code with the added Bluetooth support? Also, were you able to get Bluetooth working in the AVD?

View 2 Replies View RelatedI created the following method for retrieving stored settings from the database:
public String getEntry(long rowIndex){
String value = "";
Cursor c = db.query(DATABASE_TABLE, new String[] {KEY_NAME, VALUE}, KEY_NAME + "=" + rowIndex, null, null, null, null);
int columnIndex = c.getColumnIndex(VALUE);
int rowsCount = c.getCount();
if(rowsCount > 0){
String value = c.getString(columnIndex);
}
return value;
}
On debugging I can see cursor c contains two columns and one row but when it comes to line
String value = c.getString(columnIndex);
it throws the CursorIndexOutOfBoundsException although columnIndex = 1 which should point to a valid entry. Does anyone know what could be wrong here?
I want to be able to have two projects, one that contains production code and one that contains test code. This shouldn't necessarily be an Android-specific question, but I'm want to write some unit tests for some non-platform-specific Android code on the host PC.
I created a new Java project so I can run the unit tests on the PC and only include the non-platform-specific classes from the Android project. Both projects are opened in the same Eclipse workspace. I assume I need to somehow include these Android-project sources explicitly in the new project where I'll run the Junit tests, but I can't figure out how to do this.
For changing from portrait to landscape mode i have done some changes in manifest.xml and included some code in test.java file
In manifest.xml i have included <activity_name android:configChanges="orientation"/>
i entered some data in portrait mode. but when i rotate my mobile from portrait to landscape the control goes to onConfigurationChanged() method.
public void onConfigurationChanged(Configuration newConfig) { super.onConfigurationChanged(newConfig); setContentView(R.layout.screen1_landscape);
}
I want to call a USSD (http://en.wikipedia.org/wiki/USSD) command and have the reply returned as a String. I can make the device automatically dial the USSD - like so
// String encodedHash = Uri.encode("#"); String ussd = "*" + encodedHash + "105" + encodedHash; startActivityForResult(new Intent("android.intent.action.CALL", Uri.parse("tel:" + ussd)), 1); //
This calls the USSD and the result is displayed in an alert menu generated by the OS dialer. There's no way that I can see to intercept the USSD reply, prevent the dialer displaying it, and then use the result as a String. Essentially, all I really want to do is (pseudo code) // String ussdReply = call("*#105#"); // I've tried creating an "onActivityResult" but it never receives anything from the startActivityForResult. So, does anyone know how I can use the reply within an application?
I have an AppWidget which provides a summary of some data stored and controlled by my main Application. (In a similar way to a Calendar AppWidget showing the next event from the main Calendar application). I want to know the best practice for retrieving the data to update my widget. I have followed the example, and I have extended AppWidgetProvider and have a working widget, onto which I can update. I would expect to read the data from my main application and then update it via my AppWidgetProvider's onUpdate() routine.
Now, is the best practice here for my separate main application to provide the data via a ContentProvider? I assume so, as my Appwidget is not part of the same application. Is it possible to access a ContentProvider inside my onUpdate() routine? Before writing my main application content provider I started to test out retrieving some available data like Contacts information, and showing say a contact name in my widget, to show I can extract data from an existing ContentProvider. When accessing the Contacts contentprovider, the examples talk about:
1) Activity.managedQuery(), but my AppWidget is not an activity. 2) ContentResolver.query(), but I can't work out how to get a valid ContentResolver so I can access the Contacts. getContentResolver() does not appear to be defined for AppWidgetProviders. Am I approaching this the correct way?
I'm kinda new to android programming so please bear with me. I'm having some problems with retrieving records from the db. Basically, all I want to do is to store latitudes and longitudes which GPS positioning functions outputs and display them in a list using ListActivity on different tab later on. This is how the code for my DBAdapter helper class looks like:
public class DBAdapter
{
public static final String KEY_ROWID = "_id";
public static final String KEY_LATITUDE = "latitude";
public static final String KEY_LONGITUDE = "longitude";
private static final String TAG = "DBAdapter";....................

I am making an application that asks the user for userid, appends the userid to a static HTTP link to retrieve the user's daily schedule info file that has a .ical (calendar) extension. I need to read the data from file, format in new UI and representing some useful data on an Android device. My query is can I access a static HTTP link behind the scenes? And when I use the same link on desktop browser, it asks user to save the file — how can I do this on a mobile? Do I need to read the data and save it somewhere or I can save the .ical file and read from it?
View 2 Replies View RelatedI have the following issue; a couple of months ago i had a Desire z (happy HTC One owner now) but it fell and it broke. Or atleast the phone itself/ screen does nothing. However i can hook the phone up to my pc and its get recognized and i can browse the phone with the command prompt.
My phone broke while i was on a trip in Thailand and unfortunately the info (email adresses from new friends) that i typed into google keep that night had not been synced yet...
I would very much like to get this info off of my phone and read it or transfer it to my new phone or something (reading it on the pc has my preference as my HTC One is not rooted).
I'm looking for a way to programmatically save an array of shorts as PCM data. I know that this should be possible, but I haven't found a very easy way to do this on Android.Essentially, I'm taking voltage data, and I want to save it in PCM format. My function looks something like this:public void audifySignal(short[] signal) {// Create a WAV file from the incoming signal}Any suggestions would be awesome, or even references. Seems like the audio APIs built in to android are more geared for directly recording from the mic, and not so much for lower level signal processing type work (at least for saving raw data to a file). I'd also like to avoid having to manually write the PCM file headers and what not.
I'm writing an app that will periodically send information out to a remote server, and then get relevant information about other users from that server back to the local database.What's the best way to handle sending out this info (i.e.: XML or binary) and writing it to the remote server.Also,how can I assure that, when 500+ users' data get's to the server or FTP (or better alternative?) at once, the appropriate fields gets overwritten or added, without skipping any or overwriting the entire thing?
View 1 Replies View RelatedI met this problem at writing contacts by API for Android 2.0 or greater. Each time I write the same contact which already exist in my account (Google account) I got some part of contact aggregated ok but other did not. For example fields like FN, N, ORG, TITLE always are in one copy but TEL, EMAIL, ADR are added extra so after 2nd writing the same contact I have to copy the same TEL or EMAIL. How to force API engine to not repeat existed data?
View 1 Replies View RelatedI need to explore the world "You wrote a killer application, but do you have an Android/iPhone/iPad client?".
My questions are:
1) which is the best way to send data to those devices? Soap and Rest as suggested here? Or are there some specific techniques? (My app is written in Delphi and I can expose data with webservices if needed)
2) For x-platform (where by x I mean basically apple products and android) development is there a tool? Or the only solution is write one client per platform that "embeds" a web application optimized for mobile devices?
3) which are the techniques for caching locally some data / working offline? Is it different in the 2 worlds or is it common?
I am developing an application that read data from sensors and write those data to an XML file when you press a key. i have 2 activity one for button and another is an Activity who implements sensorEventListener. the problem is my main activity is button and couldn't get data from event listener activity. i think the listener activity is not active but when i create an intent and start activity with that intent the program stop working. the button is able to create XML file solely.so how could i read sensor data from sensors,and how to send them to XML file when the button got clicks.

View 1 Replies View Relatedhow do you stream certain bits of information from a website. From what I understand webview launches a web page, but what if I want to only stream a paragraph that was published on a site. Example: Yahoo! Fantasy Football. Updates on players and the news feed about them.This is obviously a lot more complicated than my question. I would be interested in a tutorial that could walk me through this. Does this also take programming on the server side to send this out?

I am interested in obtaining information from my band's Joomla website and placing it into an Android application. At the moment I'd like to get News articles posted and potentially other information that I create on the site. I was thinking of doing this by setting up RSS feeds for the website.

View 1 Replies View RelatedI am looking into developing an App that will convert a website into more readable data for an android app. I am at university and have an online notice board which can be viewed on the web but if possible I would like to transfer this into an app on android to make it more easy to read on mobile devices.
What I thinking is that the app would go to the website where the notice board is held and read in the html code to display each notice in a list adapter view. Each notice is within its own div so I assume I could use that to split each notice up into its own button on the list adapter view. Is this possible and if so how I can go about doing this. I have tried google for an answer but I have not yet found a solution to this problem.
