I did 3 years of Android SDK Development, I feel that the bottle can not go further, so spent more than a year time, probably touch the way. Based on the experience of predecessors, the Android low-level full entry takes two years.Let me start with my introductory process:0th step, download the source code, I under the 4.2, the framework layer source code 10G, the core 2G more, ctags to the framework layer of the label files have 600M, at that time le

The main idea is to create a blank file with the size of the target file, and then segment the data into this blank file.You can get the exact size of the file in the server by sending a head request, and then split the length into chunks of data that are set by the GET request.Request header information, you can determine the starting length and end length of the downloaded file in a single thread.For example, the target file size 900M, when downloading, open three threads to download, size = 3
