android移动数据上网的开关的实现
本帖最后由 CSDN_Ask 于 2013-01-10 11:20:25 编辑 解决办法中使用到了ConnectivityManager类，但是在SDK中的ConnectivityManager类并没有提供setMobileDataEnable()、getMobileDataEnable()等方法。也看了ConnectivityManager类的源码，里面都是有这些方法的。弄了大半天，最终狠下心来，自己写个ConnectivityManager类，其中的方法和源ConnectivityManager类的方法一样，但都是空实现，编译成ConnectivityManager.class文件，然后替换android.jar包中的android.net.ConnectivityManager.class文件。然后在项目中，使用ConnectivityManager的setMobileDataEnable()方法来打开和关闭数据上网，使用getMobileDataEnable()方法获得当前连接状态，当然这需要android.permission.CHANGE_NETWORK_STATE和android.permission.ACCESS_NETWORK_STATE权限。
