zip file(s) , put zip file (name my_raw_files.zip) folder res/raw in eclipse , packaged app. can copy @ first start of app external storage ("sdcard"):

private static final file user_dir = new file(environment.getexternalstoragedirectory().getabsolutepath() + file.separator         + "myfolder"); ... boolean dircreated = user_dir.mkdirs(); if (dircreated) {   filesutil.unzipfiles(this.getresources().openrawresource(r.raw.my_raw_files),                     user_dir.getabsolutepath()); } ... static public void unzipfiles(inputstream zipis, string outputpath) {     try     {         // unzip files existing folder structure         zipinputstream zin = new zipinputstream(zipis);         try         {             zipentry ze;             while ((ze = zin.getnextentry()) != null)             {                 if (!ze.isdirectory())                 {                     log.d(tag, "unzip " + ze.getname());                      bytearrayoutputstream baos = new bytearrayoutputstream();                     byte[] buffer = new byte[1024];                     int count;                     fileoutputstream fout = new fileoutputstream(outputpath + file.separator + ze.getname());                     while ((count = zin.read(buffer)) != -1)                     {                         baos.write(buffer, 0, count);                         byte[] bytes = baos.tobytearray();                         fout.write(bytes);                         baos.reset();                     }                     fout.close();                 }             }         }         {             zin.close();         }      } catch (exception e)     {         log.e(tag, "unzip", e);     }  }
