本文探讨了不同安卓系统版本中生成的字符串结果差异，特别是针对JSON格式的变化。高版本系统生成的是标准JSON数组，而低版本系统生成的格式则不规范。文中提供了一种针对非标准JSON字符串的解析方法。

不同的手机系统版本生成string结果不一样。

高系统系统（5.1）设备，转换之后是json单元组成的jsonarray。

array.toString=[{"channelname":"DIALOG NOW","tsavailable":"0","hasprogram":"0",
"totalcount":"52","filename":"..\/images\/markurl\/mark_1482907604038.png","channelcode":"ch00000000000000001139","mixno":"1","ratingid":"1",
"columncode":"010100","npvravailable":"0","timeshiftenable":"0","tvodavailable":"0","tvodenable":"0"},{"channelname":"RUPAVAHINI","tsavailable":"120",
"hasprogram":"1","totalcount":"52","filename":"..\/images\/markurl\/mark_1446201343209.png","channelcode":"ch00000000000000001036","mixno":"2","ratingid":"1",
"columncode":"010100","npvravailable":"0","timeshiftenable":"1","tvodavailable":"1","tvodenable":"1"},

低系统设备（4.4）：

array.tostring=["{tsavailable=0, hasprogram=0, totalcount=52, channelname=DIALOG NOW, columncode=010100, tvodavailable=0,
filename=..\/images\/markurl\/mark_1482907604038.png, npvravailable=0, tvodenable=0, ratingid=1, channelcode=ch00000000000000001139,

对于含有“=”号不规范的json字符串，只能一点点分离解析，对于标准的json格式字符串直接转化。

if(str.contains("="))
{
    Map<String, Object> valueMap = new HashMap<String, Object>();
    String newstr = str.substring(1,str.length() - 1);//去掉首尾
    // LogEx.i("lxl","newstr:" + newstr);
    String [] splitArr = newstr.split(",");
    for(int j = 0;j < splitArr.length; j++)
    {
        splitArr[j] = splitArr[j].trim();//去掉首尾空格
        String [] valueArr = splitArr[j].split("=");
        String key = valueArr[0];
        Object value;
        if(valueArr.length >= 2)//防止空数据异常
        {
            value = valueArr[1];
        }
        else{
            value = "";
        }
        // LogEx.i("lxl","key,value:" + key + "," + value);
        valueMap.put(key,value);
   }

    praseChannel(valueMap);
}
else
{
    JSONObject obj = array.getJSONObject(i);
    Map<String, Object> map = getMap(obj);
    praseChannel(map);
}
