在Android上添加spdy編解碼器後使用netty連接失敗

Question

我已經使用netty編寫了一個服務器和一個本地代理。該項目在我的電腦上運行良好，但是當我改變了一下使它成爲一個android應用程序，它就無法工作。

我嘗試了很多次，發現插入下面的代碼後，事情就出錯了。

pipeline.addLast("spdyEncoder", new SpdyFrameEncoder(3)); 
pipeline.addLast("spdyDecoder", new SpdyFrameDecoder(3)); 

我比較了添加或不SPDY編解碼器之間的日誌，所不同的是

「找不到類‘com.jcraft.jzlib.Deflater’，從方法io.netty.handler引用.codec.spdy.SpdyHeaderBlockJZlibEncoder。「，所以我想問題是與jzlib deflater，但我真的不知道如何解決它。任何人都可以幫助我，事先要多謝。

這裏是logcat的：

您需要com.jcraft.jzlib添加到類路徑。這是通過添加jzlib jar完成的。
