Android Show image by path

i want to show image in imageview without using id.

i will place all images in raw folder and open 

     try {
            String ss = "res/raw/images/inrax/3150-MCM.jpg";
             in = new FileInputStream(ss);
        buf = new BufferedInputStream(in);
        Bitmap bMap = BitmapFactory.decodeStream(buf);
        image.setImageBitmap(bMap);
        if (in != null) {
         in.close();
        }
        if (buf != null) {
         buf.close();
        }
    } catch (Exception e) {
        Log.e("Error reading file", e.toString());
    }

but this is not working i want to access image using its path not by name

try { // Get reference to AssetManager
AssetManager mngr = getAssets();

        // Create an input stream to read from the asset folder
        InputStream ins = mngr.open(imdir);

        // Convert the input stream into a bitmap
        img = BitmapFactory.decodeStream(ins);

  } catch (final IOException e) {
        e.printStackTrace();
  }

here image directory is path of assets

like

assest -> image -> somefolder -> some.jpg

then path will be

image/somefolder/some.jpg

now no need of resource id for image , you can populate image on runtime using this

You might be able to use Resources.getIdentifier(name, type, package) with raw files. This'll get the id for you and then you can just continue with setImageResource(id) or whatever.

int id = getResources().getIdentifier("3150-MCM", "raw", getPackageName());
if (id != 0) //if it's zero then its not valid
   image.setImageResource(id);

is what you want? It might not like the multiple folders though, but worth a try.

read a stream of bytes using openRawResource()

some thing like this should work

InputStream is = context.getResources().openRawResource(R.raw.urfilename);

Check this link

http://developer.android.com/guide/topics/resources/accessing-resources.html#ResourcesFromCode

It clearly says the following

While uncommon, you might need access your original files and directories. If you do, then saving your files in res/ won't work for you, because the only way to read a resource from res/ is with the resource ID

If you want to give a file name like the one mentioned in ur code probably you need to save it on assets folder.
