帮你 顶个

最好上日志

[SmarkMeng]

郁闷还是没找到办法

[jacyGmail]

直接报错 灰格格 还是其他 ？

[SmarkMeng]

是直接报的错，现在已经解决了，原来是我的mainfest.xml里少加了 <uses-library android:name="com.google.android.maps" />

thank ！

[ch_984326013]

呵呵，LZ问题解决了就好。地图需要在AndroidMainfest.xml
<uses-library android:name="com.google.android.maps" />
同时还要添加网络权限吧。

java.lang.ClassNotFoundException: 这种通常最有可能就是忘记写对应权限了。 看到这个先查权限
