我想使用非阻塞IO读取后台进程的流/输出，谁能给我一个关于如何在Android上使用非阻塞IO的示例吗？
谢谢您的帮助。
最佳答案
这是the class I use，可以从Internet下载文件或在文件系统中复制文件以及如何使用它：
// Download a file to /data/data/your.app/files
new DownloadFile(ctxt, "http://yourfile", ctxt.openFileOutput("destinationfile.ext", Context.MODE_PRIVATE));
// Copy a file from raw resource to the files directory as above
InputStream in = ctxt.getResources().openRawResource(R.raw.myfile);
OutputStream out = ctxt.openFileOutput("filename.ext", Context.MODE_PRIVATE);
final ReadableByteChannel ic = Channels.newChannel(in);
final WritableByteChannel oc = Channels.newChannel(out);
DownloadFile.fastChannelCopy(ic, oc);
还有选择器方法，这里有一些关于选择器，通道和线程的很棒的（Java）教程：
