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.

I don't see anything about this change in the API differences report at http://developer.android.com/sdk/api_diff/8/changes.html. However when my Nexus One started running Android 2.2, the list of files created by the following code are now in reverse alphabetical order rather than alphabetical order (as they were with Android 2.1 and earlier, AFAIK):
CODE:.........
The line "Arrays.sort(fn);" revives the alphabetical order of the list, but sorts are computationally expensive and AFAIK the explicit call to Arrays.sort() was unnecessary prior to Android 2.2.
In addition to seeing this order change on the Nexus One, it can be confirmed on the emulator running level 7 and level 8 AVDs.

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.
Using Android 1.5

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.

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?

Is there any way out there to organize your apps menu other than by alphabetical order? When you have a heaps of different apps and are always trying new ones like me it's not always easy to find that one that has a name that relates nothing to its function.Ideally I'd like some way of making categories in my app menu and and grouping all my utility icons, all my game icons etc.

I am configuring a tablet for my grandparents, and I am struggling to find an Android keyboard which arrange keys in alphabetical order (A B C D ...) instead of QWERTY.
I am not looking for a keyboard with combined keys using dictionaries like dialpad/T9 (which would be too complicated for them), I just need a basic keyboard with one virtual key per letter.
I thought that this would be very common and easy to find, but it's not The only applications that I found are :
Keyboard for Senior Citizens : would be perfect but does not scale up correctly on tablet.
Keyboard for Dyslexics (lol) : seems to be exactly the same as the "senior" version, did not try because it s an other pay app and has same developer, screenshots and description.
Kids Keyboard : Scale problem in landscape on tablet : too small.
Alphabetical Keyboard : takes the whole screen in landscape on tablet.
Simple Large Button Keyboard : Scale problem in landscape on tablet : too small.
SlideIT English - ABC pack : layout addon for SlideIT keyboard, but I don't like the suggestion panel remaining on the top.
Dextr Alphabetic Keyboard : the only functional from the list, but I would rather use a design closer to a traditional keyboard.
If any better keyboard with ABCD order or a keyboard which would let me customize the layout, I would be very interested.

Is there a way to re-arrange the applications list in grid view in alphabetical order?
If I switch to "list view", they are in alphabetical order, but in grid view, they are not. I could not find a way to do it.

Does anyone else have problems with the music player ordering your songs in alphabetical order instead of in the order they appear on the original album? I've never had this problem with iTunes or iPhone, but with Droid X, all of my MP3 albums are ordered in this way. (FYI, the issue is the same if it's an actual MP3 or AAC format.)

Does anyone know how to fix the default Music player's behaviour when long-pressing on an album and selecting "Play" ?
If you start playing by quick-pressing the album, it shows you the list of songs. If tagged correctly, this list is in correct song order, and will play the album in order from whichever song you select to start from. If not tagged correctly, it shows in alphabetical order.
So far, so good.. can't complain... BUT...
If you start playing an album by long-pressing it and selecting "Play", it plays it alphabetically, regardless of the status of the tagging.

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.

Is the assets folder only accessible to the app or can the user see it too? For my app I want to store a credential certificate and video files on local storage but I am not sure how to hide these items from the users. The assets folder seems like the only choice.

The instructions for my app are in HTML format in my assets so I can display them with proper formatting and hyperlinks in a WebView. Given that they're in the assets folder, not res, I can't properly localize them (i.e. something like assets-de wouldn't work). What's the proper way to localize embedded HTML files?

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?

I 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:
Typeface tf= Typeface.createFromAsset(getAssets(), "advertising.ttf");
TextView converted = (TextView)findViewById(R.id.TextView03);
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 have been working on creating a Grid View of images, with images being present in the Assets folder. http://stackoverflow.com/questions/1933015/opening-an-image-file-inside-the-assets-folder link helped me with using the bitmap to read it.My application does read the image from the Assets folder, but it is not iterating through the cells in the grid view. All the cells of the grid view have a same image picked from the set of images. Can anyone tell me how to iterate through the cells and still have different images?

It seems that the Android resource compiler does not take into account linked folders (in Eclipse sense) in the assets folder. Question - is there a way to forcibly designate a folder of my choice as Android project assets? Short of copying or hardlinking into project assets, I mean.
