Suppose, you have a larger database of customers, such as 5000 records. Using a simple select query it can take 2-5 seconds on a mobile application to populate a listview with all thousands of customers available. But the user only needs to select one, so what is the best way to select the customer?

Maybe some of you has an application with quotations or jokes or something. I would like to make a similar. So how can I get the i. element of my string array (which is in arrays.xml)? I don't want to load the whole array in a String[], because it can be too big. Or it's not a good idea to put them into arrays.xml? How do you handle thousands of strings?

View 2 Replies View RelatedWhy are there thousands of warnings when building Android? I don't understand it. Is it because of the wide variety of compilers out there that people use that results in different output when building? Or is it because the code is so poorly written and developers just don't really give a damn?
I know for a fact that when my team or me individually build(s) an application, we/I are/am sure to have clean code with no warnings about "comparison between signed and unsigned...", "x may have no been declared", "format not a string literal and no formatting characters", "expected type1 but argument is of type2"... etc. I, for one, am very troubled by these thousands of warning when building Android.
The display of my Samsung Galaxy i7500 has failed after I accidentally dropped the phone on a table! The phone can however receive calls.
I would like to clear/reset the data before I hand over the phone for repair.
Is there any way I can do a reset (clear all SMS, application data, cache, etc.) from a PC connected to the mobile via USB? Is there a key combination which would achieve the same?

View 2 Replies View RelatedMy ultimate goal is to limit records that are able to be created so that I can have a trial version of my application. I'm thinking I can do this rather simply by returning an int variable within a sqlite count statement, and using a simple IF statement to determine if a new record should be created.

View 3 Replies View RelatedSo i have been recording a good amount of pool side videos in 720p on my EVO. I usually home movies through my western digital tv box with all my movies loaded on portable hard drives. So today i decide to take some movies from my phone to the hard drive and i realized that the phone records in 3gp. Why 3gp? That may be an old cell phone format but its not what todays 720p movies really record in. Does anyone have any recommendations for a conversion software or file type to convert these movies. It seems kind of useless to record movies that can only be watched back on a computer. And i know its not a canon hidef camcorder that cost over 1k. Its a cell phone.

I've just started working with SQL and Android and from what I can see, updates and inserts back to the database need to be handled individually?
I can retrieve a Cursor containing multiple records, but if I wanted to apply an update to each record in the cursor, I can only see how to do this individually, using ContentValues and Update(), and then the cursor requires reloading??
Same with if I wish to create multiple new records, these appear to be required to be inserted individually? Can I not create a List and bulk insert?
To me this seems slow and cumbersome, and there has to be something I'm not yet aware of (searching for answers is failing me... likely due to using incorrect terms being new to android/java)
Here's a very simple example of what I basically what I want to achieve, however there must be a better way to achieve this functionality. (I know there are some other bad practises in here, just creating a quick eample)
