This article describes the Android programming development implementation with a progress bar and a percentage of multithreaded downloads. Share to everyone for your reference, specific as follows:
Following the previous "Java Multithreading download instance detailed", it can be transplanted into our Android, the following is the specific implementation of the source code:
Downactivity.java:
Package com.example.downloads;
Import Java.io.File;
the CPU divides the time slice to perform alternately, if a application uses 99 threads to download the file, then it occupies 99 user resources. Suppose the average CPU execution time allocated to each thread in one second is that the 10ms,a application gets 990ms of execution time in one second of the server, while the other applies only 10ms execution time in a second. Just like a faucet, where the amount of water per second is equal, it must be more than 10 milliseconds to put 990 milliseco
