Android :: Play Audio File From Assets Directory
Jul 20, 2010
when I run this code, it starts playing all the audio files in the assets directory, in alphabetical order instead of just playing the audio file I requested. What am I doing wrong? Is there a better way to play audio files from the assets directory?Is there a difference between keeping audio files in the assets directory and keeping them in the res/raw directory? Besides the fact that they don't get ids if they are in the assets directory. If I move the audio files to the res/raw folder then I have a problem with reusing MediaPlayers because there is no id parameter for setDataSource(). I can't find a good guideline for handling this kind of problem.

I get a lot of requests in my application to allow for custom icons packs from BetterCut / Open Home. The way it seems to work is you install BetterCut or Open Home, then you can install tons of these free icon packs from the market. Once installed both those apps (and other apps) will poll for those icon packs and use the icons. I want to know how to poll the install applications for the asset folders that are available. I have opened up a few of the icon packs and verified that there is an assets folder in there and they are full of all the icon png files. I've searched on here, other code sites, google, etc., but haven't found any leads.
From the answer below I have written some code to try and list a file from my own projects assets directory but it does not seem to work.
Resources r = this.getResources();
AssetManager a = r.getAssets();
String[] list = a.list("/");
Log.d("test", "Length of / is "+list.length);
for (String s : list) { Log.d("test", s); }
Log.d("test", "Length of /assets is "+a.list("/assets").length);
Log.d("test", "Length of /assets/ is "+a.list("/assets/").length);
Log.d("test", "Length of /assets/ is "+a.list("/assets/").length);
Log.d("test", "Length of ./assets/ is "+a.list("./assets/").length);
Log.d("test", "Length of ./assets is "+a.list("./assets").length);
This is the output:
03-16 12:25:04.591: DEBUG/test(13526): Length of / is 6
03-16 12:25:04.591: DEBUG/test(13526): AndroidManifest.xml
03-16 12:25:04.591: DEBUG/test(13526): META-INF
03-16 12:25:04.591: DEBUG/test(13526): assets
03-16 12:25:04.591: DEBUG/test(13526): classes.dex
03-16 12:25:04.591: DEBUG/test(13526): res
03-16 12:25:04.591: DEBUG/test(13526): resources.arsc
03-16 12:25:04.614: DEBUG/test(13526): Length of /assets is 0
03-16 12:25:04.637: DEBUG/test(13526): Length of /assets/ is 0
03-16 12:25:04.661: DEBUG/test(13526): Length of /assets/ is 0
03-16 12:25:04.692: DEBUG/test(13526): Length of ./assets/ is 0
03-16 12:25:04.716: DEBUG/test(13526): Length of ./assets is 0
I figured out that you can read from the assets directory without actually using the folder name:
InputStream is = assetManager.open("test.png");
I also tried this with an asset in Appliction 2 from Application 1, where the folder path is /asset/icon/image.png:
InputStream is = assetManager.open("icon/image.png");
Next I figured out that you can list a directory inside assets:
String[] list = assetManager.list("icons");
That also works great. The only thing failing right now is how to list the base directory assets.

I've got an activity that calls a helper class called DownloadManager. DownloadManager spawns a thread that downloads a mp3 to the sdcard. I'm having some trouble finding the best design for resuming the initial activity and starting the MediaPlayer. Does it make the most sense to use a BroadcastReceiver that receives a message that download is complete, then start a new Intent of my activity? Think I saw something that I can't use an Intent to start an Activity from BroadcastReceiver because it is a background process.

I copied song.mp3 to my project's assets directory and wrote this code:

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.

Does Android have a "best practices" guideline on creating & populating the db/tables programmatically vs. deploying a .db file in assets?
What are the pros/cons of both approaches?
I have a db with big long strings in several columns, and about 50 rows, so writing the insert statements alone would take quite some space. It seems a waste.

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.

Is there an Android equivalent to the iOS Core Audio / Audio File Stream Services? I need to be able to read audio bytes from a network and feed them to the audio system under my control, so I can do my own timeouts / reconnects / range requests / etc. without interrupting the audio playback (since the system audio thread would be playing audio already enqueued). It seems that MediaPlayer doesn't give me this level of control. Is there a lower-level framework that does, either in the SDK or NDK?

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?
