I have an URL pointing to content and I need to get highest value contained in one of the columns. Is there any aggregate function that will accomplish that or do I have to do this manually?

This has got me all confused! I'm trying to return the max value from a column in my database but the return value is always the name of the column.
The query I use:
private static final String SELECTMAX = "SELECT MAX(?) FROM " + TABLE_NAME ;
The (test) function to return the max value:
CODE:............
The column i'm querying is an INTEGER type but the result 's' is always the column name and not the desired value.

ONLY POST YOUR ACTUAL CPU TEMPS, NOT BATTERY TEMPS.
I noticed that google maps does not display anything when at the highest magnification on my droid. This is true when satellite is on or off. Have any of you noticed this? I find it works like this when wifi is on or off.
I see a gray background with a few magnifying glasses instead. I thought it might be because there are no images near my house at this level, so I tried Manhattan near MSG and still did not find anything at the highest mag level.
I have my settings on 8MP and Highest quality. Yet my pic sizes are only 800kb and the quality is horrible. any suggestions?

I want to design a table whose first column items remain fixed when user scrolls horizontally, but should scroll when the user scrolls vertically. Similarly the first row items remain fixed when user scrolls vertically, but should scroll when the user scrolls horizontally. Can this be achieved using a TableLayout? Or is there any other combination of widgets that I could use?
View 2 Replies View RelatedOne of my android apps performs the following specific SQLite query:
CODE:................
Now that works on some Android phones, but on a few of them it crashes with the following error:
CODE:..................
For some reason, "-1" is interpreted as a column rather than a number... that doesn't make much sense and when I read the SQLite query language I see no need to escape this number in parentheses. Could it be an issue of a different version of SQLite? Would adding parentheses this help any? Instead, I'll probably rewrite it using >= 0 but still I'd like to understand what's going on.
I'm having trouble with something that works in the Notepad example.
Here's the code from the NotepadCodeLab/Notepadv1Solution:
CODE:.................
This code seems to work fine. But just to be clear, I ran the adb utility and run sqlite3 I inspected the schema as follows:
CODE:...............
All seems good to me.
Now on to My App, which as far as I can see is basically the same with a few minor changes. I've simplified and simplified my code, but the problem persists.
CODE:..............
When I run my app, I get a RuntimeException and the following prints in LogCat from my Log.e() statement:
LogCat Message: java.lang.IllegalArgumentException: column '_id' does not exist
So, back to sqlite3 to see what's different about my schema:
CODE:.................
I don't see how I'm missing the '_id'.
Can anyone point out what I've done wrong?
One thing that's different between my app and the Notepad example is that I started by creating my application from scratch using the Eclipse wizard while the sample app comes already put together. Is
there some sort of environmental change I need to make for a new app to use a sqlite database?
I'm not big into UI programming so this may be an easy thing I overlooked. I am trying have a screen that shows 8 TextView in a 2 column x 4 row table. And, of course, I want the TextViews, that might have different lengths, to be centered. I tried this in a table layout, for obvious reasons but I feel like this is not the way to do it because it doesn't have much control where I put everything once it is in a row. Should I be using a different combinations of layouts or is there something I overlooked.

Can I add a column of data to the Contacts db, such as birthday, favorite color, whatever. Or does the platform/ framework make this difficult? If possible, would I do it through the contacts content provider?
View 4 Replies View RelatedI read that the different entries in different tables are linked via the _ID column in that table. For example a contact might have an _ID = 1 I get via
ContactsContract.Contacts._ID
And now I want to read the phone number of that contact using
CODE:.............
This works fine, but what I would expect is that if the _ID of the contact is 1 that the _ID of the phone number is as well one since they belong together, but they are not equal. So the question is how does Android match these entries?
This is an incredibly dumb question. So, apologies. But I can't find the answer anywhere and it's driving me nuts.
In DDMS, I have lost the tag column, i.e. the first part of the message from Log.d(tag, message). I can see time, log type, process id, and message - but not tag!
