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").

My app depends on 3 different files. I already put the two larger ones as expansion files which seems to work fine. Now I don't know where to put the third one (small file). I tried the raw folder but actually I don't know what the path of the file is once it is in those folders.
I tried this here for the raw folder
myClassifier.loadModel( pathToExpansionFiles + "/File1",
pathToExpansionFiles + "/File2",
R.raw.File3);
However the return value of R.raw.File3 is an integer, but the function myClassifier expects a string that is the path to File3. Has anyone an idea how to do that?
I tried the raw folder but actually I don't know what the path of the file is once it is in those folders.
There is no path to it. That is a file on your development machine. It is not a file on the device. It is merely an entry inside your APK file.
but the function myClassifier expects a string that is the path to File3
Either switch to some library that works with an InputStream (from getResources().openRawResource()) or make a copy of the data to a local file using that InputStream yourself.
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);
I wanna include a text file to my project in smartface appstudio. I put it where? In resources folder or assets? FileStream could not read it in resources (as a drawable item). Any idea?
var txtFile = new SMF.IO.FileStream(SMF.IO.applicationResources, "words.txt", SMF.IO.StreamType.read);
txtFile.readToEnd();
It is not implemented in current release of Smartface App Studio. Also I have tried it before. It is Phase 2 for File Operations.
You can download your static text file from the internet and can save it to the local storage. And read it from there. I can just suggest you this idea. Check some helpful links below.

I need to get Absolute path to Folder in Assets.
Some like this for sd-card:
final String sdDir = Environment.getExternalStorageDirectory() + "Files";
What i do incorrect?
First I try to get path (in green ractangle) this way but I alwase get "False".
Then I comment this block and try to get path from getAssets().list();
But I get 3 folders witch I see first time.
I want to make massive like this "green" but I need to use files from assets:
Look the image
Help me to get absolute path to my Files folder.
I'm not exactly sure what you're trying to do, so I'll try to cover the bases, and maybe this will help.
If you are just trying to get a list of what's in your assets, then
use getAssets().list("Files"). (You have to use the subdirectory,
because of this).
If you are trying to get an absolute path to your assets directory
(or any subdirectory), you can't. Whatever is in the assets directory
is in the APK. It's not in external storage like on an SD card.
If you are trying to open up files in the assets directory, use
AssetManager.open(filename) to get the InputStream. Here,
filename should be the relative path from the assets directory.
EDIT
I'm not sure what you mean by "massive", but if you want to load the file black.png from assets instead of the SD card, then write this:
// must be called from Activity method, such as onCreate()
AssetManager assetMgr = this.getAssets();
mColors = new Bitmap[] {
BitmapFactory.decodeStream(assetMgr.open("black.png"));
// and the rest
};
Assets are stored in the APK file so there are no absolute path than your application can use. But, I would suggest to take a look at file:///android_asset. It might fits your needs. Here is a good example on how to display an Asset in a WebView.
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.
