我使用的是 httputil 发请求，它给我回的是一段 json 字符串，我用 android5.0.2 的手机调试时，能正确返回 json 字符串，格式如下 ：
{"desc":"OK","status":1000,"data":{"wendu":"21","ganmao":"天气转凉，空气湿度较大，较易发生感冒，体质较弱的朋友请注意适当防护。","forecast":[{"fengxiang":"东风","fengli":"3-4 级","high":"高温 24","type":"小雨","low":"低温 18","date":"6 日星期二"},{"fengxiang":"东南风","fengli":"4-5 级","high":"高温 23","type":"小雨","low":"低温 16","date":"7 日星期三"},{"fengxiang":"东北风","fengli":"微风级","high":"高温 22","type":"小雨","low":"低温 14","date":"8 日星期四"},{"fengxiang":"西风","fengli":"微风级","high":"高温 21","type":"晴","low":"低温 13","date":"9 日星期五"},{"fengxiang":"西北风","fengli":"3-4 级","high":"高温 19","type":"多云","low":"低温 12","date":"10 日星期六"}],"yesterday":{"fl":"微风","fx":"东风","high":"高温 22","type":"小雨","low":"低温 18","date":"5 日星期一"},"city":"马鞍山"}}
但是使用另一个 android4.0.3 的手机调试时，却得到返回的错误码，返回如下：
{"desc":"invilad-citykey","status":1002}
我在 AndroidManifest.xml 文件中设置的是
android:minSdkVersion="15"
android:targetSdkVersion="22"
/>
控制台报错如下：
01-02 11:32:46.609: E/PhonePolicy(5505): Could not preload class for phone policy: com.android.internal.policy.impl.PhoneWindow$ContextMenuCallback
01-02 12:40:20.569: E/dalvikvm(11859): Could not find class 'android.telephony.CellInfoGsm', referenced from method com.baidu.location.h.c.a

01-02 12:40:20.529: W/dalvikvm(11859): VFY: unable to find class referenced in signature (Landroid/telephony/CellInfo;)
我使用了百度定位sdk，应该和这没关系吧
不知道怎么回事，希望遇到类似情形的前辈指导，不胜感激。
你的so文件添加完整了吗？

不是4.0+和5.0+的关系
没有找到类，系统问题吧
