I have a .gif file inside the assets folder like this assets/Files/android.gif. when I try to open the file it throws an exception at the second line.
CODE:...........
so is it that I'm trying to open an image file despite that the same code works if I try to open a text file?

View 3 Replies View RelatedHow 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.

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?
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.
How to read data from the assets folder sqlite database file with .sqlite extension in my Android application?

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.

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

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?

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.

View 1 Replies View RelatedI have 5 mp3 files stored on the assets folder. The files are all 25 KB. I load the files using:
manager = context.getAssets();
this.inputStream = manager.openFd(fileName).createInputStream();
Whenever I try to play the files, the sounds are all messed up like they were mixed or something.
I've zip aligned the app already but with no results.
What I am trying to do is simply copy over entire folder full of mp3 files onto sdcard within an app. I am doing this out of "assets" folder because raw folder does not allow mp3 files to be named the way I need them to. Here is what I dug up so far but not sure if this will work. I am lost.
InputStream ins = getResources().getAssets().open(""); int size = ins.available();
// Read the entire resource into a local byte buffer. byte[] buffer = new byte[size];
ins.read(buffer); ins.close(); FileOutputStream fos = new FileOutputStream("/sdcard/myfolder/");
fos.write(buffer); fos.close();
I want to change the font in my widget such that it uses a specific font in "assets" folder of my app. I usually do this in my app to change the font:

converted.setTypeFace(tf);
And it works like a charm. How can I do this in widgets? I can only set the text and change the color:
remoteView.setTextViewText(R.id.TextView03,"some text" );
remoteView.setTextColor(R.id.TextView03, Color.BLACK);
But I don't see a way to set the font.

I am using a text file in assets folder in Android. I would like to change the data inside that text file dynamically. I am trying to open the file as follows,
CODE:...........
But it generating the error that "java.io.FileNotFoundException: This file can not be opened as a file descriptor; it is probably compressed". please help me to edit that file.
I'm going crazy, I created a file object, so it can be read with ObjectInputStream, and I placed the assets folder.
The method works with a file smaller than 1M, and give error with larger files.
I read that is a limit of Android platform, but I also know that can be "easily" avoided.
Those who have downloaded the game Reging Thunder, for example, can easily see that in their assets folder is a file 18.9M large.
This is my code ...
now I have an uncompressed file and I can use it without worrying about the error "This file can not be opened as a file descriptor; it is probably compressed"
This function works well with files smaller than 1M, with bigger files return an
java.io.IOException on line "ObjectInputStream ois=new ObjectInputStream(is);"
why?
