The code that caused the exception at com.danikula.videocache.file.FileCache.available(FileCache.java:46)

//old code ： @Override public synchronized long available() throws ProxyCacheException { try { return (int) dataFile.length(); } catch (IOException e) { throw new ProxyCacheException("Error reading length of file " + file, e); } }

//change code @Override public synchronized long available() throws ProxyCacheException { try { long fileSize = dataFile.length(); return fileSize; } catch (IOException e) { throw new ProxyCacheException("Error reading length of file " + file, e); } }

this is error log: com.danikula.videocache.ProxyCacheException: Error writing 8192 bytes to java.io.RandomAccessFile@530f0a3 from buffer with size 8192.

备注：缓存失败的原因是 文件的类型 （long） 被强制转换成了（int）类型 ，int类型的长度不够，从而导致文件缓冲失败。
