Question

I am newbie to android don’t know much about it. I have imported a image to my project and when i tried it check it using File that the file exists or not.

This is the code i have used..

 existingFileName="res/drawable-ldpi/login.png";  
 File f= new File(existingFileName);  
      //  Log.d("Image path",);  
        if(f.exists())  
        {  
            Log.d("EXISTS", "====File Exists===");  
        }

Still it is showing me no image exist.

thanks for help in advance,

If you store the image in the “res/drawable” folder you can do:

Drawable drawable = getResources().getDrawable(R.drawable.name)

See http://developer.android.com/reference/android/content/res/Resources.html#getDrawable

For the case you store your image in the assets folder, you need to use getAssets() ( http://developer.android.com/reference/android/content/Context.html#getAssets() )

You can do something like this:

InputStream is = getAssets().open(imageName);
BufferedInputStream buf = new BufferedInputStream(is);
Bitmap bitmap = BitmapFactory.decodeStream(buf);

Remember that for both case you need to have a Context (ie an Activity)
