Android :: Efficient Way To Make Database Query Faster ?

Sep 3, 2010

In my android app i need to get 50,000 database entry(text) and compare them with a value when the activity started(in onCreate()).I am doing this with the simplest way : i get the whole table from db to a cursor.However this way is too laggy.Are there any other way to do it more effective?The app is "scrabble solver" that is why i am not using WHERE close in my query (Take the whole data annd compare it with combination of the input letters).At first i was using a big table which contains whole possible words.Now i am using 26 tables.This reduced the lag and i am making database call on a thread that solved a lot problems too.It is still little bit laggy but much better.

Android : Resizing Bmp Before Setting It On Remote View Make It More Efficient?

Apr 28, 2009

Can someone know the answer tell me which is more efficient if the bmp is a big bmp? RemoteViews views

1. views.setImageVIewBitMap(R.id.icon, bmp)

2. bmp = BmpUtils.resizeToFitIconSize(bmp) views.setImageVIewBitMap(R.id.icon, bmp)

In short, will resizing the bmp before setting it on a remote view make it more efficient? Or should I just let the imageView take care the resizing? Code...

I'm populating a listview from a database query and I can't seem to figure out what is going wrong.

As you will see in the image, the query is returning some sort of id. I've done a ton of googling, but the problem is that I don't know what to search!

Android :: Make Games Faster?

May 17, 2009

I have done a simple game where I draw on a View and use invalidate() to force onDraw to be called. This however doesn't seem to scale at all since even for this little game it is quite slow. So what is the solution, to use openGL? that is what all games should? and then I should use frames rather than redrawing?

Android :: Android ContentProvider Database Query Multiple Tables

May 7, 2010

I'm writing an RSS reader for Android. I've faced a certain difficulty which the problem I can't resolve since databases aren't my expertise.. So i figured out maybe one of you could help me out! I currently have 3 tables (Categories, links and feeds). My goal is too link a feed to multiple categories. Therefor I'm using a Link table. My databases is an Android ContentProvider (sqlite) and looks like the following:

| Categories | | Links | | Feeds |
|------------| |---------| |-------|
| _ID | | Category| | _ID |
| Title | | Feed | | Title |
| URL |

I currently wrote the following code in my FeedListActivity to retrieve a list of links and their feeds.

CODE:.................

Now my question:

I was wondering how I could optimize this database layout, code or query so I would get my entries in a more efficient way. Because i believe this link table or the query to retrieve links isn't needed! Or am i doing this the correct way?

Android :: Make Droid Emulator Run Faster?

Apr 18, 2010

The Android emulator is a bit sluggish. For some devices, like the Motorola Droid and the Nexus One, the app runs faster in the actual device than the emulator. This is a problem when testing games and visual effects.

How do you make the emulator run as fast as possible? I've been toying with its parameters but haven't found a configuration that shows a noticeable improvement yet.

Samsung Galaxy S :: Make Run Faster?

Aug 6, 2010

i have a 3-week old Galaxy S and i'm loving it. but i noticed that it seems to be "slower" in some ways (compared to the iPhone 4) in the way it open & closes an app, the way it loads an app sometimes, the way it animates in going back to previous screens or menus and in general really. don't get me wrong it's quick but having a 1GHz processor i'm kinda left feeling and wanting.

Motorola Droid X :: How To Make Faster?

Oct 1, 2010

Like every one here I want my phone to operate at it's optimal speed. But I really don't know what makes this phone fast. Why are there different quadrant scores on stock phones? Does running certain programs slow this phone down? I know that without rooting the phone the processer can't be over clocked, and when I had 2.1 rooted I had SetCPU installed, and you didn't have the ability to overclock the phone anyway. I guess I don't understand why someone reports a Quadrant score of 1450, and someone running the same platform reports 1350. Not that I think you would know the difference between the two.

HTC Droid Eris :: Make Faster / Better?

May 4, 2010

I Got Open Home, and GDE. Used those for a while. and I like those. Sense is meh... But lately i've been noticing a lot of lag as well. I can barely finish a text without my phone lagging... >.< I would like to speed it up.... But I would also like to keep my warranty intact, I've seen some options. Updating to the Leak 2.1 v3 or Rooting. of these two I would prefer rooting... I like options lol like i said. and 2.1 v3 traps you on 2.1 v3 forever (as of now >.< )

Both of which seem to void warranty...... So my question Is... What should i do with my phone?? Is it worth it to say F*ck the warranty and root? is there something (BESIDES TASK KILLER!!!) that i can install to make the ENTIRE phone run faster? EDIT: OH!!! and i forgot. One of my big fears in rooting is the set up process after the root. Like will I have to call some Verizon number and re activate my phone like they did when i first got it??

Samsung Galaxy S :: How To Root To Make Phone Faster?

Aug 20, 2010

I am new to Android and rooting. I have a Galaxy S and love it! I didn't even know what rooting was. I just came across it after looking for ways to make my phone faster. After a while I realized my phone speed slowed down and was looking for the reason behind it. That's when I learned rooting is the answer. So I used the One Click method and everything is fine so far.

My Kernel is 2.6.29 root@SE-S602 #2 and Baseband is XXJF3 (2.1). So I went into my apps and saw the superuser permission app. But it doesn'thttp://android.bigresource.com/add/add.php work! It is just a blacked out screen. So I am not sure where to go from here. I have tried searching for an answer but couldn't find one, just guides how to root. How to make my phone faster from this point? I get confused with all these ROM things! Which is the best ROM? MoDaCo? Is there a Froyo version of it?
