今天收到一个bug；是红米上用wifi在web端接收文件，web端输入ip地址时，红米崩溃；
然后查看崩溃日志：java.util.zip.DataFormatException: stream error；发现是在android
在网上查了查，就看到说是使用GZipUtils方法进行GZip压缩时android4.4.4手机上会报错
gos.finish();
gos.flush();
去掉其中一个；
不过试了一下还是崩溃，就在项目里找到用这个压缩方法的地方；
public void writeTo(OutputStream outstream) throws IOException {
if (outstream == null) {
throw new IllegalArgumentException("Output stream may not be null");
}
InputStream instream = new ByteArrayInputStream(this.byteArray);
if (!isGzipByteArray) {
outstream = new GZIPOutputStream(outstream);
}
try {
copy(instream, outstream);
} finally {
instream.close();
}
}
protected void copy(InputStream instream, OutputStream outstream) throws IOException {
byte[] tmp = new byte[Constants.Config.BUFFER_LENGTH];
int l;
while ((l = instream.read(tmp)) != -1) {
outstream.write(tmp, 0, l);
}
if (outstream instanceof GZIPOutputStream) {
//注意流关闭顺序
((GZIPOutputStream) outstream).flush();
}
//注意流关闭顺序
outstream.close();
}
然后在GzipUtils里面
public void gzip(InputStream from, OutputStream to) throws IOException {
GZIPOutputStream gos = new GZIPOutputStream(to);
int count;
byte[] buffer = new byte[Config.BUFFER_LENGTH];
while ((count = from.read(buffer)) != -1) {
gos.write(buffer, 0, count);
}
/**
* 只需要一个finish()即可，否则会造成stream err,崩溃
* @author subowen 2016-12-15
*/
gos.finish();
// gos.flush();
}
这样就不崩溃了；哈哈 菜鸟一枚，也不确定主要是什么问题，不过解决了
