I'm having trouble retrieving image references from my database and then setting them to an ImageView. When I pass R.drawable.icon into my database its compiled and stored as an Integer. how would I then pull this Integer out and use ImageView.setImageDrawable(); ?

I want store an image using a SQLite database in Android (using an insert statement).Also I need to retrieve the image from the SQLite database and display it on the screen.
View 1 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 created a database with records in it and everything. I am trying to use its fields and put it in a spinner. The database contains university names.
I created a spinner with:
CODE:............
where I am feeding the spinner the records from an array. I want to do it from the database that I created. I read thru the classes and there are 2 ways but I can't find a proper code to use any of them. I just want to insert the code to get records from the database. It shouldn't be complicated is it?
I would like to store an object into a SQLlite database. I am looking for how to best do it in order to ensure that if I need to updata/change this object in the future that users of the new and old object layout will be minimally impacted. In other words I want to ensure that making changes to the object will have minimum affect on clients that do not update their software on the old database format.
I want to also ensure an easy update from the old record style to the new format. I was thinking that I could add an element in the SQL row to identify the object type with a unique name, and to identify the object version number. That way I could read the row and use the object number to control the deserializer to use the correct version of the class.
I need some help to store a Object in an SQLite database using Android.I don't know whether it is possible or not.If it is possible means please give some code snippets to create a table which can store an object.
View 1 Replies View RelatedI am working on some sample programs, where i have to take the value from the user and store it in the database. I have used DroidDraw to create the XML code for UI.For now, I have just started with a textbox. So, I have to take the value from this textbox and store it in a database. I am using SQlite browser to create tables. I read in some forums, that one way of doing this.
1. Copy the db file in the asset folder of the android project and use the AssetManager class. But i am not able to figure out how to use the asset manager class here. Or if I could get some simpler suggestions on how to store the value from user into the database, it would be great.

View 1 Replies View RelatedSo I have an app where I put arbitrary strings in a database and later extract them like this:
CODE:......................
This works fine in all cases except for when the string looks like a float number, for example "221.123123123". After saving it to the database I can extract the database to my computer and look inside it with a DB-viewer, and the saved number is correct. However, when using cursor.getString() the string "221.123" is returned. I cant for the life of me understand how I can prevent this. I guess I could do a cursor.getDouble() on every single string to see if this gives a better result, but that feels sooo ugly and inefficient.
I just made a small test program. This program prints "result: 123.123", when I would like it to print "result: 123.123123123"

I am developing an app on Android that will randomly pick and display an inspirational quotation (or verse) from a large collection of quotations. On Android I can choose between a flat file and an SQLite database. The app should satisfy the following conditions:
Be scalable to 10^6 quotations and/or verses
Be very fast (i.e. retrieve and display a quotation, immediately at the touch of a button)
Be able to load new quotations from an external source (in a format I have not yet decided)
What data format must I use?

I 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?)

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.

View 3 Replies View RelatedWhat 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?

However, when the app is resumed, the mediaplayer isn't retrieved, so hitting pause just starts a new player so now there are two sounds playing.
Is the mediaplayer a type of service? How can I access the original player again?

Or even better, are there alternatives to synchronizing data in such an application?
