APN开关啊急!!!!!!!!!!!!!!!

[ajq1989]

做APN开关是遇到问题

ConnectivityManager mConnectivityManager = (ConnectivityManager) getSystemService(CONNECTIVITY_SERVICE);
mConnectivityManager.setMobileDataEnabled(true);

setMobileDataEnabled 提示错误
The method setMobileDataEnabled(boolean) is undefined for the type ConnectivityManager
网上找了是此方法被隐藏.改怎么调用啊?

可是我已经加了还是一样提示这啊

你配置文件里加个这个 android.permission.WRITE_SECURE_SETTINGS 权限再试试

自行编译framework.jar，把这个jar包加入工程的classpath，直接调用
