io.dcloud.common.adapter.ui.WebLoadEvent报错

我在发布的app中加了全局错误捕获代码，发现2016年1月22日发布的安卓离线打包版本，有比较多的手机会在以下位置（WebLoadEvent.java:352）报错。涉及到的机型比较多，如
"vivo Y18L"
"CHM-TL00H"
"SCL-AL00"
"vivo Y29L"
"M512"
"KIW-TL00"
"ZTE A880"
"Redmi Note 2"
"vivo X5L"
"X800"
"vivo X6D"
"HM 1S"
"HUAWEI TIT-TL00"
"X800"
"HM 2A"
"HM 1S"
"Redmi Note 3"
"HM NOTE 1S"
"R6007"
"SM-G3818"
"MI NOTE Pro"
"SM-A7000"
"NX512J"
"HUAWEI GRA-CL10"
"Redmi Note 2"
"HUAWEI C8817E"
"OPPO R7sm"
"HM 2A"
"Redmi Note 3"
"HUAWEI TIT-TL00"
"8676-A01"
"Redmi Note 3"
"KIW-AL10"

报错内容如下：
