在当前程序中没有对wifi断开进行处理,所以出现以下异常:
11-04 11:09:35.889: E/DownThread(7389): Connection timed out 11-04 11:09:35.889: E/DownThread(7389): java.net.SocketException: Connection timed out 11-04 11:09:35.889: E/DownThread(7389): at org.apache.harmony.luni.platform.OSNetworkSystem.read(Native Method) 11-04 11:09:35.889: E/DownThread(7389): at dalvik.system.BlockGuard$WrappedNetworkSystem.read(BlockGuard.java:273) 11-04 11:09:35.889: E/DownThread(7389): at org.apache.harmony.luni.net.PlainSocketImpl.read(PlainSocketImpl.java:458) 11-04 11:09:35.889: E/DownThread(7389): at org.apache.harmony.luni.net.SocketInputStream.read(SocketInputStream.java:85) 11-04 11:09:35.889: E/DownThread(7389): at java.io.BufferedInputStream.read(BufferedInputStream.java:319) 11-04 11:09:35.889: E/DownThread(7389): at org.apache.harmony.luni.internal.net.www.protocol.http.FixedLengthInputStream.read(FixedLengthInputStream.java:44) 11-04 11:09:35.889: E/DownThread(7389): at java.io.BufferedInputStream.read(BufferedInputStream.java:319) 11-04 11:09:35.889: E/DownThread(7389): at java.io.FilterInputStream.read(FilterInputStream.java:133) 11-04 11:09:35.889: E/DownThread(7389): at com.tvie.ivideo.download.logic.DownThread.run(DownThread.java:65)
出现异常的代码是InputStream的read方法。
while ((len = is.read(buffer)) != -1 && running) {
read方法的声明表现会抛出IOException。
int java.io.InputStream.read(byte[] buffer) throws IOException
