ocr - Copying asset files to SD Card (file not found)? -

i'm trying copy files tesseract use , no matter how try keeps giving me filenot found exceptions. don't understand why because have them in assets folder. tried 1 way copying specific tessdata folder wasn't working tried putting them under general assets folder , copying each file in there new directory created on card called tessdata.

here's image of files in folder, method copying , log errors post:

and here's code:

private void copyassets() {     assetmanager assetmanager = getassets();     string[] files = null;     try {         files = assetmanager.list("");     } catch (ioexception e) {         android.util.log.e(tag, "failed asset file list.", e);     }     for(string filename : files) {         inputstream in = null;         outputstream out = null;         try {           in = assetmanager.open(filename);           out = new fileoutputstream(tesspath+ "/" + filename);           copyfile(in, out);           in.close();           in = null;           out.flush();           out.close();           out = null;         } catch(ioexception e) {             android.util.log.e("tag", "failed copy asset file: " + filename, e);         }            } } 

-i tried using method example copied them tessdata folder within assets-

if (!(new file(tesspath + file.separator + lang + ".traineddata")).exists()) {         copyassets();         /* try {             assetmanager assetmanager = getassets();             //open asset manager , open traineddata path             inputstream in = assetmanager.open("tessdata/eng.traineddata");             android.util.log.e(tag, "opened if no error before this");             outputstream out = new fileoutputstream(tesspath + "/eng.traineddata");             android.util.log.e(tag, "writing  to" + tesspath);             byte[] buf = new byte[8024];             int len;             while ((len = in.read(buf)) > 0) {                 out.write(buf, 0, len);             }             in.close();             out.close();         } catch (ioexception e) {             android.util.log.e(tag, "was unable copy " + lang                     + " traineddata " + e.tostring());             android.util.log.e(tag, "im printing stack traces");             e.printstacktrace();         }         */     } else {         processimage(storage_path + file.separator + "savedandroid.jpg");     }
