Android :: Can't Increase Value Of A Record In Droid / Sqlite Database / How To Do
Aug 6, 2010I try to increase the value of an integer key in a row in my table. However, nothing really seems to happen.
db.rawQuery("UPDATE table SET key = key + 1 WHERE name=?", new String[] {name});
However, this code works fine (just sets the key to a hard-coded value):
ContentValues values = new ContentValues();
values.put("key", 2);
db.update("table", values, "name=?", new String[] {name});
Also tried '?' instead of just ?, but it resulted just in a run-time error.

Android :: Valid Network Exists
Dec 23, 2009I am struggling to find a way to determine if a valid network is available to an app. specifically, if there's a problem making a network connection, i would like to be determine if it's on the client (app) side, or a problem with the remote server. i happen to be attempting a URL connection (using http client) and the wide and varied possible exceptions don't seem like a reliable method. for example, when the network is down on the phone, i received "unknown host exception", which doesn't really indicate the root cause ... it's possible to get that exception with a valid network connection also. at other times i get other exceptions, such as socket exception. is there a way to ask the phone if it's network ready? the other option i thought was to ping a known good server to see if it responds ... with an IP address. kind of a heavy weight option and not foolproof.

Android :: SQL Efficiently Check - An Association Exists
Nov 5, 2010I have a database of notes and lists, with three association tables.
Basically, lists are parents of notes and other lists, and notes can be parents of other notes in a outline like hierarchy.
I am using this query to return all notes within a list as well as the number of subnotes each note has.
CODE:...................
This query works just fine, but it's overkill. I don't need to return count(n2.note_id) as Num_Subnotes because I'm only using that value to check if the note has ANY SUBNOTES AT ALL. Essentially it's a boolean value where 0 is false and > 0 is true.
It seems to me that counting all those records is a waste of time when I could just return 1 after finding the first matching value.
Is there a more efficient way to check if count(n2.note_id)>0 in the above query?
Android :: To Mock Sqlite3 Cursor When No Db / Table Exists?
Sep 16, 2010I am using a ContentProvider for caching results from a web-service query. It is an HTTP request and the response content is XML. Most of the data is cached, so I simply query the DB, if not found, request from webservice, insert in DB and requery the DB. Thus the response is always a Cursor from SQLiteDatabaseHelper.
I have one result set that is not stored in the DB and since it is 100% transient, but I would like to provide the appearance of it coming from the DB's Cursor. Is there an easy way to do this? For example, if I could project it onto the cursor with a cursor.setValue("string", objectValue) or some other existing implementation.
If not, I will either bypass the DB for this content result, or stuff it into a trivial table that is constantly reused.

Sprint HTC Hero :: Messages App Problem Exists After Update
Nov 18, 2009I have yet to see this problem mentioned in this forum and it's very specific problem which is hard to describe but I will do my best.
Problem: Opening messages app takes me to my last conversation and auto-opens the softkeyboard.
I've found only one work-around for this. It goes as follows
Workaround: Start the Hero up and wait until you have at least 2 text messages. Open the notifications window and click the "new messages" notification. This will open up the messages app showing all conversations then click Home. Once doing this, no matter what you do, clicking the messages app will always take you to all conversations rather than the last conversation you had open.
If I access the first new text message, upon starting the phone, in any other manner than stated above I get the problem where after viewing a specific conversation and clicking Home, I open the messages app and it goes back to that specific conversation.
