Uploading Images to Server android

Question

I wanted to know which is the best way to upload image to server without loosing its quality  I have searched on google found various methods of posting data  But I am not sure which one would be best to upload  I came across    Multipart Image Upload   Uploading images using byte array Uploading images using base64 encoded string    I have tried Base64 encoding it leads me to OOM Out of memory  if image is too high in resolution  Any tutorial which tackle this issue would be appreciated   Thanks in advance
