Android BufferedReader ReadLine（）得到了IOException-预期为十六进制块大小，如何解决此问题？

Question

I`m using BufferedReader in Android to receive http stream connection , when parse message I received use code:

url = new URL(HOST_URL_PUSHMESSAGE);
urlConnection = url.openConnection();
in = (InputStream) urlConnection.getContent();
reader = new BufferedReader(new InputStreamReader(in));
line = reader.readLine();
in.close();

It looks work well but Sometime I got IOException - Expected a hex chunk size,but was.. Happened in:

line = reader.readLine();

How does this happen & How can this be resolved? Does change bufferedreader size help? Thanks

See the source http://www.java2s.com/Open-Source/Android/android-core/platform-libcore/org/apache/harmony/luni/internal/net/www/protocol/http/ChunkedInputStream.java.htm The exception happens there

try {
    bytesRemainingInChunk = Integer.parseInt(chunkSizeString.trim(), 16);
} catch (NumberFormatException e) {
    throw new IOException("Expected a hex chunk size, but was " + chunkSizeString);
}

Looks like something incorrect in the data.
