Android :: Read LARGE Sqlite File To Be Copied Into Emulator - Or Device From Assets Folder

May 28, 2010

I guess many people already read this article:

Using your own SQLite database in Android applications: http://www.reigndesign.com/blog/using-your-own-sqlite-database-in-android-applications/comment-page-2/#comment-12368

However it's keep bringing IOException at

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

I'am trying to use a large DB file. It's as big as >8MB. I built it using sqlite3 in Mac OS X, inserted UTF-8 encoded strings (for I am using Korean), added android_meta table with ko_KR as locale, as instructed above.

However, When I debug, it keeps showing IOException at

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

I suspect it's caused by trying to read a big file. If not, I have no clue why.
I tested the same code using much smaller text file, and it worked fine.

Can anyone help me out on this? I've searched many places, but no place gave me the clear answer, or good solution. Good meaning efficient or easy.

I will try use BufferedInput(Output)Stream, but if the simpler one cannot work, I don't think this will work either.

Can anyone explain the fundamental limits in file input/output in Android, and the right way around it, possibly?

Android :: File Dialog - Allow User To Specify Folder/filename On Storage For Creating An SQLite Database

Jan 19, 2010

Is there something like a FileDialog available? From previous threads, it appears there isn't one.

If not, has someone written one?

I want to allow a user to

a) Specify a folder/filename on storage for creating an SQLite database.

b) Specify an existing file/folder on storage card for opening as an SQLite Database.

Android :: Read A GZIP File In The ASSETS Folder

Mar 2, 2010

How can you read GZIP file in Android located in the "ASSETS" (or resources/raw) folder?

I have tried the following code, but my stream size is always 1.

GZIPInputStream fIn = new GZIPInputStream(mContext.getResources().openRawResource(R.raw.myfilegz));
int size = fIn.available();

For some reason the size is always 1. But if Idon't GZIP the file, it works fine.

Android :: Determining Filetype Of File In Assets Folder

Jun 9, 2010

Question: How do you programmatically distinguish between directories and regular files in the assets folder?

When using AssetManager to access files in the assets folder, it seems impossible to determine if a file is in fact a file or a directory. You get the list of files from the list method and then open the file using the open method. I thought perhaps using the openFd method to get the asset file descriptor (and then subsequently requesting the normal file descriptor) would provide me some information. But requesting the file descriptor for a directory results in an IOException (which makes sense since what would it mean for a directory to have a file descriptor...?).

Currently I'm relying on that IOException (resulting from attemptng to open a directory in the assets folder) in order to determine if a file is in fact a directory. (Opening a regular file works just fine). This seems like a bad idea. Any other suggestions to distinguish between a file and a directory?

Android :: Check For File Existence In Assets Folder

Aug 28, 2010

My app has .txt files in subdirectories in the assets folder. It reads those .txt files and puts them in a textview. It's working great and no problems.

Should I be concerned about the files in the assets folder getting deleted by the user or missing. If this ever could happen, my app would get an error because the file would not be there when it tried to read it into the stream.

Is there a need for me to check the existence of an asset file before I read it or does the asset manager take care of it all? I also was wondering if there's a chance that a user would or could delete and asset file.

Like I say, everything works fine without me inserting code to check for file existence. I just wondered if people use the .exists() statement every time they go to read in a stream from assets.

Android :: Assets-Folder - Takes Always The First File By Alphabetical Order

Oct 17, 2010

I'm new in Java/Android programming, so please have patience with me.

I try to play a mp3 which is locate und the assets folder. I know there is another way with the /res/raw/ folder, but use the assets-folder because later I'll try to access the file by String.

This code works to play a mp3-file:

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

Now the problem: In the same assets-folder is another mp3 file stored. Though I specify the name of the mp3 to use it take the one which comes first in alphabet. E.g. the other file is named "music.mp3" it plays this one. Renaming it to "worldmusic.mp3" it will play "song.mp3". Rerename "worldmusic.mp3" back to "music.mp3" it will take this mp3 again. Another test: Renaming "song.mp3" to something other so the application can find whats specify by the code above will result that no song is played. So this means the songname have to exist, although it take arbitrary the song first in alphabet.

I'm testing with the AVD emulator of eclipse. But I think the behaviour would be the same on a real device.

Android :: SQLite - Inserting String With New Lines Into Database From Csv File

Sep 9, 2010

I am trying to inject a long text entry into a SQLite database, in a TEXT field. This text has new lines in it (i.e. it spans multiple paragraphs). I can get the new lines to show up if I do the INSERT manually:

INSERT INTO "LOGENTRY" VALUES(5,40,'PLACE','line1
line2
line4
',1283990533315,'4A','TEXT','',NULL);

but if I have the equivalent text in a CSV file and attempt to .import it into the table, I get an error that it's expecting more columns than exist (as soon as the new line is encountered, the program assumes it's the end of the input and thus it's missing columns). Is this possible? Or is the only way to manually do each INSERT?

Android : ContentProvider Storage/memory - Data Can Be Stored In File System - In An SQLite Database

Oct 20, 2010

Please direct me to a description of the techniques that the ContentProvider employs to access data. I am trying to understand how it works as well as what is tunable or even if its meant to be tunable. It the memory management tiered, cached, virtual, flat? Is it file based, shmem based, stream based? Can there be a combination thereof?

Any information, suggestions, or references are welcome. The android fundamentals page says: "The data can be stored in the file system, in an SQLite database, or in any other manner that makes sense;" but the android ContenProvider page barely skins the onion.

Android :: Accessing Assets That Are Larger Than 1M

Oct 6, 2009

It has come to my attention that Android can only deal with asset files that are around 1M or so. My problem is that i'm creating an app that requires access to 5 csv files. The largest of the files is 130M. I want to be able to package these text files with my app. Is there anyway around this? My app needs to be able to run without Internet access so storing these files on a server is not an option.

Android :: How To Play Videos In Android From Assets Folder Or Raw Folder?

Jun 12, 2010

I am trying to play a video in android emulator I have the video in my assets folder as well as the raw folder.But after doing some research still i cant play video in my emulator.i am working on android 2.1 My video format is mp4 so i don't think that should be a problem.Could anyone just give me an example code so that i can understand a bit more?The problem is that the VideoView that I need to display the Video will take only a URI or a File path to point to the Video.If I save the video in the raw or assets folder I can only get an input stream or a file descriptor and it seems nothing of that can be used to initialize the VideoView.

Android :: Install APK From Assets Or RAW Folder

Aug 6, 2010

I would like to install an APK from within an Android application. Can anyone give me an example of how to do this? Also how do I open the install applications from unknown resources preference page so that users can change it? I actually meant open the screen using code, so I can immediately open the preference page for the user to simply check the box, and press back. Is it possible to check to see if they allow non-market apps? Can an application request permission enough to do this?
