Thanks for the answer you saved my life...
@db0910 Thanks for your addition to VolleyMultipartRequest
Thank you! It works for me very well!
in class VolleySingleton.java
private final LruCache<String, Bitmap> cache = new LruBitmapCache(mCtx);
in this line i am getting error that
cannot resolve symbol LruBitmapCache
i am getting this in respnse, what could be the issue
com.android.volley.NetworkResponse@ed190b5
Thank you so much it's work for me

Hey, thank you so much.
Just a minor correction:
at MainActivity.java, line 98
replace "mAvatarInput" with "mAboutInput"
