OTA升级，无法找到更新包

[DESCRIPTION]
OTA升级，服务器上已经上传了新版本，但是手机检索的时候，仍然提示版本已经是最新版本，找不到更新包。
从log看：提示如下：
{"status":1000,"name":"mp.v1.1","size":4455854,"android_version":"4.2.2","release_notes":"MP.V1.1","delt
aId":181,"fingerprint":"XXXXX/vh075_td_emmc_xxxxx_s4509/vh075_td_emmc_xxxxx_s4509:4.2.2/JDQ39/1387464158
:user/test-keys"}//这个log说明找到了新的软件版本

[SOLUTION]
在对比版本的时候，会对比fingerprint值，log来看这里
12-20 09:49:20.895: INFO/SystemUpdate/HttpManager(2002): fingerPrintPkg =
XXXXX/vh075_td_emmc_xxxxx_s4509/vh075_td_emmc_xxxxx_s4509:4.2.2/JDQ39/1387464158:user/test-keys
12-20 09:49:20.895: INFO/SystemUpdate/HttpManager(2002): fingerPrintLocal =
fingerPrintLocal是获取来的本地手机的fingerprint值，这边获取为null，是因为
客户定义的版本号太长了，导致在组装成fingerprint值的时候，超出了google限制
的property的长度92 byte，这种情况下，请改小客户定义版本内容，即
XXXXX/vh075_td_emmc_xxxxx_s4509/vh075_td_emmc_xxxxx_s4509:4.2.2/JDQ39/1387464158:user
