Get some asset file path in APK

I use some class. That's constructor needs some file path that contains some files.
ex)
Komoran komoran = new Komoran("D:\program_project\lib");
Now I'm making android app. so I can't use absolute path (Because other people who download my app don't have that folder and files)
so I decide to use 'assets' folder that is maybe in APK file. So, final code is like below.
Komoran komoran = new Komoran("file:///android_asset");
but It seems like folder path is wrong(this class doesn't work). What I did wrong ?

This "file:///android_asset" path is used for applications which uses webview ex. cordova/phonegap. As it is part of resources because when Apk is created you can not use this path to access your assets folder. You have to work with context.getResources().getAssets().open("fileName")this code only.

Maybe u can add this code:
context.getResources().getAssets().open("fileName").
u will get a inputstream, and u can do something u want.

No need to use getResources.
You can use directly
context.getAssets().open("fileName").

what is OpenNLP's model file path?

I try to use OpenNLP in an Android application with eclipse, and I imported the 4 JARs into the libs folder.
It's probably a stupid question.. but where should I put the model files "en-pos-maxent.bin"? I can't find anything regarding the path anywhere
I try to run the code contains this line:
POSModel model = new POSModelLoader()
.load(new File("en-pos-maxent.bin"));
I tried putting the en-pos-maxent.bin inside a new folder within the project("tagger/en-pos-maxent.bin"), inside the libs folder, or simply give the path where the en-pos-maxent.bin is put when downloaded("Users/ariel/Downloads/en-pos-maxent.bin"), it always give me the error: POS Tagger model file does not exist path: (the path I typed in)
Could anybody help please?

When you use new File("filename") the file is expected to be in the current working directory, I don't think that's different on Android. You can use System.getProperty("user.dir") to get the current working directory. It's by default the directory you start the program from. You could also specify a full path like new File("/full/path/filename") instead.

In android the right way to add file to the application (inside APK) is to put into the assets folder. Then you can't get File object from assets folder but, you can create that File using a buffer or in you case just get it into the InputStream. For example if you will create models folder into the assets folder (assets/models), your code will look like this:
AssetManager am = getAssets();
InputStream inputStream = am.open("models/en-pos-maxent.bin");
POSModel posModel = new POSModel(inputStream);

Android Studio, using Assets Folder

So, I've seen many posts on this, but none has helped. I want to work with the assets folder, for organizational purposes. The images below show where the 'assets' folder is, along with the app.imi options of where it should be. I have tested this, and in the >exploded-aar/com../appcompat-v7/19.1.0/assets ... the files inside this seem to work. I can call on the .mp3 file and load and play it correctly (Though a few times it did not recognize it. Even when it was inside a folder, inside of the directory.)
In the src/main/assets folder, all the files are ignored. Is there a specific way I have to call this? In other words, must I also link the actual folder it is it? src/main/assets/music to load up the riseofcc.mp3?
I do not have 10 reputation to post images, so sorry for only links.
EDIT:Also I am using Android Studio 0.5.7
ANSWERED:
Thanks for Xavier Duchrohet for explaining exploded-aar is for the application's dependencies. I have learned that when calling upon a file inside your asset's folder using the code:
AssetManager assetManager = getAssets();
InputStream inputStream = null;
AssetFileDescriptor descriptor = assetManager.openFd("sound/explosion.ogg");
You must include the folder's parent inside the arguement.
Android Studio's app.iml has the asset's directory (src/main/assets) inside of its configuration's options.

Normally, to include sound files, I create a folder called raw, inside the app / src / main / res.
That is, I right click on the folder res and from the menu that appears, choose: New / Android Resource Diretory. Renaming in the window that appears, the Directory name field values for raw.
How it works for me, I hope this might have helped him.

File not found issue in Android

I need to access myfile.txt file using FileReader in Android , please suggest me where to add the text file in Eclipse. I tried it adding it in Resource and Asset but I am getting File not found issue.
FileReader fr = new FileReader("myfile.txt");
Even
File ff = new File("myfile.txt");
File Supports only the below listed parameters
FileReader Supports only the below listed parameters
Note: I want solution for this issue , only with FileReader or File

The directory would be /res/raw/ this is where you put all your extra resources.
you can refer to it using getResources().openRawResource(resourceName)
and check here Android how to get access to raw resources that i put in res folder?
EDIT:
how can i edit the text files in assets folder in android
in short
the easiest way would be to copy the file to external directory then do your stuff there
link is here
Android: How to create a directory on the SD Card and copy files from /res/raw to it?
One thing to mention - prior to 2.3 the file size in the assets cannot exceed 1MB.
hope it helps abit

That's how I obtain my file from the SD card, perhaps this can be some use to you.
String state = Environment.getExternalStorageState();
if (Environment.MEDIA_MOUNTED.equals(state)) {
File options = new File(getAppDirectory(), "portal.xml");
}
The getAppDirectory method used in the bit of code looks like this :
private String getAppDirectory() {
return new String(Environment.getExternalStorageDirectory().toString()
+ "/foldername/foldername/");
}
After this bit of code I also make sure the file exists and what not before I attempt to read from it.

android: Check the existence of a file in the application

I have few html files in assets folder of my application. My application loads these files depending on the device language. When I check for the existance of the file it say does not exist, but when I load that file using browser.loadUrl(filename), it loads it fine.
Following code will help you to understand my problem:
String filename="file:///android_asset/actualfilemname.html";
File f = new File(filename);
if(!f.exist){
filename = "file:///android_asset/newfile.html";[Everytime it loads this file even though I have actualfilename.html in the folder]
}
browser.loadUrl(filename);
[it loads the newfile.html but not actualfilename.html]

You can't use File for resources. You'll need to use the AssetManager for that.
(In the off-chance that File does handle resources, which I don't think it does, you'll have to convert the path to a URI first, for example using URI.create(). File(String) expects a path, not a URI.)

Is this the exact code you are using? you probably want to be calling f.exists() not filename.exist().
Edit: try working with the AssetManager instead of hard coding your file path. My best guess is that the file path you are using is not exactly how it supposed to be.
