Android :: Assistance With Large Datasets

May 24, 2009

I must have searched high and low for the answer to my problem.I've even spent around $100 on books hoping that one of them would cover it alas it was not the case.I have approximately 50000 records in a database table. All I want to do is display them in a list-view so you can scroll through them.I dare say I will need to lazily load them as you scroll through the list - my question is how and can it be done through a content provider? I noticed the SlowAdapter in the APIDemos that appears to do exactly the kind of thing that I am looking for, but Im unsure of the correct method for requerying the content provider with the new limit criteria (or at all via a ContentProvider). Do I need to create a new cursor and merge it with the previous one as I scroll down?

Android :: Softkeyboard Development Assistance

Sep 11, 2010

I have two android related needs:

1. I am trying to create a soft keyboard for android. I need someone to help me create the template for it: the service, the touch event capturing and sending of characters and sensing of the text buffer. Based on google's published document this seems to be standard stuff, for someone familiar with the platform. I will fill in the logic for the keyboard myself. So this is not a huge job, but a few hours of consulting dollars.

2. We are two programmers, trying to learn android. We are looking for a tutor of sort, whom we can pay hourly and talk to or skype with 2-3 hours a week. again, not a huge job, but a little money on the side.If you feel up to it, please contact me.

HTC EVO 4G :: Need Some ROM Manager Assistance

Sep 25, 2010

I am using ROM manager. I am using a stock 2.2 after update. I rooted with unrevoked. So, I am trying to back this up. When I choose a name for it, it turns into the dreaded white EVO 4G screen and never does anything until I pull battery, and reboot the phone.I guess it's safe to say this is not going to work and I have to manually do the backup, etc? With all those steps.You see, what I want to do is put Fresh on my EVO ...dab a little in custom ROMS.

Motorola Droid X :: Root Froyo OTA - Assistance

Sep 23, 2010

I tried the easy root instructions here:

How to: Root DROID X Running Official Android 2.2 - Droid Life: A Droid Community Blog

when the bat was running, it kept telling me that adb was not a valid command.

The entire process only took 30 seconds or so.

I suspect adb is not installed, or the sdk is not installed completely. My phone still is on, and appears normal, and is still plugged into the pc.

How can I check to see if it is indeed rooted, and if not, how to I install adb (link?) so it does root properly?

I have some specific questions, I have tried to read every single thread I can and considering I have only had the HTC Hero for 2 days I feel Im pretty clued up.My first concern if anybody would like to advise me..is internal memory. I have had the phone 2 days and only have 81 mb of internal memory left. I have just ordered a class 4 8G SD Card with adaptor, plus a USB reader for it....Now my question are:

1. when these items arrive should I partition the card? if so which method is the safest and "least" technical to ad apps2sd.....

2. With the supposed arrival of 2.1 (Im currently running cupcake 1.5), is it worth adding a new ROM to my Phone? I am not suffering any lag as yet so is it worth it?

3. How much data usage does streaming radio on Radio Time use up listening to it for an hour or so? (that one is just a shot in the dark if anybody has any ideas!

4, What benefits does Dolphin provide over the standard browser?

5. Are the any apps that improve the Camcorder cos boy does that thing suck?

I have just moved over from a Symbian Sony Ericcson and I am astonished with the Hero. I may be a little behind the times but its a solid user friendly awesome phone. I hope 2.1 lives up to its expectations (and provides Flash 10.

Android : Reading Rss.xml Is Too Large Url

Android :: Managing Large Graphic Set

Sep 14, 2009

I'm writing a game for a computer class that I'm currently taking for school. The game has a lot of graphics associated with it (mostly in .png format). There is too much data to simply include it as part of the 'res'. The way i'm currently doing it, is to store all of the graphics in a single zip file, in a folder on the SDCard, e.g., / sdcard/Game/PlayerImages.zip (or whatever). And then i'm using the ZipInputStream to read from those, then using the BitmapFactory to decode the stream and then draw them on the canvas. The problem that I'm having is that this method is terribly slow if I add a lot of images into the zip file. The best way I have found thus far is to name the .png files within the zip numerically, then use a for-loop to jump directly to a specific file, but this is still a very slow way of doing it. I would like to use a single file (like zip) to hold all of the files for several reasons. 1., i'm trying to use a file container so i can simply update graphic 4.png and then push it into the zip file (for example) from a server. 2., because android sees all image files on the sdcard when you open the gallery application. 3., easier to prevent data manipulation by doing an md5/sha-1 checksum on 1 zip file, rather than every time a file is opened if it weren't in a container.

Android :: How Do A Display A Large Animated Gif Given A Url

May 1, 2009

Suppose I have the URL for large animated gif and I wanted to make a youtube like activity that displays the animation in a streaming way. How do I

stream in the image?
get it do display with actual animation?

I know ImageView is not the answer as it only shows the first frame.

A bonus would be having access to its buffering status so I can synchronize streaming sound as well -- this is part of a YTMND viewer application. While I could create a service that transcodes the public gif files into a nicer format, I'd like the app to function without additional dependencies.

Android :: Any Application For Handling Large PDF Files?

Jul 20, 2010

I am looking for an application that can handle large PDF files smoothly. I have tried adobe reader, pdf viewer and RepliGo. They were not very impressive, therefore I have come here for suggestions. Repligo reader I think was better out of the three but I couldn't view a PDF file that had scanned images on it. Was hoping someone could recommend an app that could handle large PDFs and PDFs that contained scanned images.

Android :: Avoiding Compression On Large Files

Sep 29, 2010

Apparently you can't have a file in "assets" larger than 1MB (except for certain file types) because it's considered too large to uncompress. But I'm finding mixed info about how to circumvent this limitation. Some say that you can put the files in "raw" and avoid the limitation but others say that files in "raw" are compressed too.And there's the -0 aapt option that can be used to turn off compression for certain file types, but there's no way to specify aapt options in Carbide. I realize that I can break the file into pieces, but that's error- prone on both ends.And using one of the known uncompressed file types not only confuses things but also runs the risk that the Android PTB will decide to start compressing that file type.

Android :: Resuming Large File Download

Sep 17, 2009

I am trying to implement the functionality to resume a large file download, but have not found how to start downloading from a position that is not at the beginning of an InputStream.I am currently using the InputStream.skip() method to go to the position where I want to resume the download, but have found that this method actually reads all the data over the network and then throws it away.I would appreciate some help in learning the correct way to start reading from the resume offset of the internet file being downloaded, so that I can avoid wasting the phone network bandwidth, and also avoid the extra time delay caused by re-downloading all the data that was already previously downloaded.

Android :: Large Data File / How To Deal With It?

Dec 10, 2009

My application needs to intensively manipulate (read-write) on some structured text data.The size of the data is significant 1Mb. And there is initial data available for the user to start with.My idea is to put this data as a file in the .apk. Then, on initial application launch to read this data and populate Android SQLite database with it. Then just work with this database. But after the database is populated the data file is no longer needed. And I'd like to remove it to free some memory. Alternate approach is to work with this data file instead of SQLite database. But I assume SQLite would work a magnitude faster then i/o on my data file..
