I am trying to unzip a String value. But I am getting a java.io.IOException: Push back buffer is full
public byte[] unzipArray(String stringToUnzip) { byte[] inputByteArray = Base64.decode(stringToUnzip); ByteArrayInputStream byteArrayInputStream = new ByteArrayInputStream( inputByteArray); ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();
ZipInputStream zipInputStream = new ZipInputStream(byteArrayInputStream);
try {
ZipEntry theEntry = zipInputStream.getNextEntry();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
byte[] buffer = new byte[2048];
int size = 2048;
while (true) {
try {
size = zipInputStream.read(buffer, 0, buffer.length);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
if (size > 0) {
byteArrayOutputStream.write(buffer, 0, size);
} else {
break;
}
}
return byteArrayOutputStream.toByteArray();
}
