有没有办法在拥有Lollipop或更高版本（代码中）的Android上禁用/启用数据连接？

Answer 1

int currentapiVersion = android.os.Build.VERSION.SDK_INT;


if (currentapiVersion >= 21) {
    // Do what u want (eneble or disaqble) eg. u want to enable in this condition

 Method dataMtd = ConnectivityManager.class.getDeclaredMethod("setMobileDataEnabled", boolean.class);
            dataMtd.setAccessible(true);
            dataMtd.invoke(connectivityManager, true);




} else {

     // Do what u want (eneble or disaqble) eg. u want to disable here


Method dataMtd =     ConnectivityManager.class.getDeclaredMethod("setMobileDataEnabled", boolean.class);
dataMtd.setAccessible(false);
dataMtd.invoke(connectivityManager, false);
}
