Android :: Saving File On SDcard (Android Beginners No Longer Working)
Aug 17, 2010Android Beginners is no longer working so I have to post this here. Here's is the case scenario that I would like to do, but I've been googling with no luck. There's text info that the user saved on the drive.
1. I want to open up a dialog, for the user with a listing of the file structure
2. The user can then choose where to save the file
3. Then I want to save the file there
Can anyone offer me simple code for step 1,2,3 that I can use?
Android :: Android - Retrieving All Drawable Resources From Resources Object
Jul 11, 2010In my Android project, I want to loop through the entire collection of Drawable resources. Normally, you can only retrieve a specific resource via its ID using something like:
InputStream is = Resources.getSystem().openRawResource(resourceId)
However, I want to get all Drawable resources where I won't know their ID's beforehand. Is there a collection I can loop through or perhaps a way to get the list of resource ID's given the resources in my project?
Or, is there a way for me in Java to extract all property values from the R.drawable static class?

Aug 16, 2010I replaced my original sdcard with a sandisk 16gb card. Everything went well until I started getting these blasted read on errors. Earlymon suggested a fix from another board but I don't have a stand alone card reader so I couldn't do it that way.

Android :: Retrieving Data From The Database
Jul 10, 2009I 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?
Android :: Using Listpreference And Retrieving Key String
Mar 23, 2010I have a settings menu that pops up and in it is a listpreference type menu. It is associated with a settings.xml file where there are 'array-strings' within it. It all works good but I don't know how to retrieve the users preference. As an example, let's say the user picks a color (red, green, or blue). The list that I've made within my 'array-strings' contain the text red, green, and blue. Within my code, I would like to do something if the user has choosen red, something else if they choose blue, etc., etc. Would I use a 'case' statement or an 'if' statement? And most importantly, how would I retrieve the users preference - the key? (am I checking for a boolean?)

Android :: Retrieving Data From USSD Command
May 17, 2009I 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?
Android :: AppWidget Retrieving Data From Another Application
Apr 30, 2010I 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?

View 3 Replies View RelatedAndroid :: Retrieving XML / Stream From HTTP (Parsing XML)
May 4, 2010What are the best practices parsing XML from an HTTP resource in Android? I've been using HttpURLConnection to retrieve an InputStream, wrapping it with a BufferedInputStream, and then using SAX to parse the buffered stream. For the most part it works, though I do receive error reports of SocketTimeoutException: The operation timed out or general parsing error. I believe it's due to the InputStream. Would using HttpClient instead of HttpURLConnection help? If yes, why? Should the stream be output to a file, having the file parsed instead of the stream?

Android :: Retrieving And Parsing ICal Data Over HTTP
Jan 23, 2010I 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?
