Accessing FAT32 and NTFS format USB Pendrive from android tablet
What you need is a way to enable support for NTFS in the kernel on your device. This could be achieved dynamically by building the ntfs-driver as loadable module (.ko file). This would need to be done for the specific version of the kernel that is running on your device.
Next you need a way to automatically load the module each time the systems restarts. this is also "do-able" in Android. You might want to try this app which does precisely that. i.e. load one or more kernel module(s) located anywhere on the Android device.
After this whenever one inserts a external-device(usb-drive) that has ntfs partitions, the kernel will be able to properly recognise and mount it. Hence apps can then access it at its proper location like "/mnt/usbhost1" etc.

Button createFile = (Button) findViewById(R.id.createFile); createFile.setOnClickListener(new OnClickListener() { public void onClick(View v) { try { File root = new File("/mnt/usbhost1"); Runtime.getRuntime().exec("chmod 777 " + root.getAbsolutePath()); File myFile = new File(root,"createNew.txt"); myFile.createNewFile(); Toast.makeText(getBaseContext(), "Done Creating File", Toast.LENGTH_SHORT).show(); } catch (Exception e) { Toast.makeText(getBaseContext(), e.getMessage(), Toast.LENGTH_SHORT).show(); } } });
