Android - Efficient way to load multiple images from remote server

Question

I have an Android application that would retrieve data (images+text) from a php remote server and display them in a GridView. I am doing the operation in the background usin

Answer 1

IMO - there are 2 issues , moving the images across the network to the client and getting them loaded.

Assuming that you are using http as the protocol, you should have a multithreaded solution for http as is available in apache httpclient package. That will get the pictures to the phone fast.

Then , you have to present the pics by getting them into memory and a cache. Here you can consider what 'gallery3D' app does with its grid and bitmaps but its pretty complicated to read thru that code.
