我一直用这个code以编程方式启用移动数据：

I've always used this code to enable mobile data programmatically:

ConnectivityManager conman = (ConnectivityManager) context.getApplicationContext().getSystemService(Context.CONNECTIVITY_SERVICE);
@SuppressWarnings("rawtypes")
final Class conmanClass = Class.forName(conman.getClass().getName());
final Field iConnectivityManagerField = conmanClass.getDeclaredField("mService");
iConnectivityManagerField.setAccessible(true);
final Object iConnectivityManager = iConnectivityManagerField.get(conman);
@SuppressWarnings("rawtypes")
final Class iConnectivityManagerClass = Class.forName(iConnectivityManager.getClass().getName());
@SuppressWarnings("unchecked")
final Method setMobileDataEnabledMethod = iConnectivityManagerClass.getDeclaredMethod("setMobileDataEnabled", Boolean.TYPE);
setMobileDataEnabledMethod.setAccessible(true);
setMobileDataEnabledMethod.invoke(iConnectivityManager, true);

这效果不错，除了现在在Android 4.4.2，我得到这个异​​常：

This worked well, except now on Android 4.4.2 where I get this exception:

java.lang.NoSuchMethodException: setMobileDataEnabled [boolean]

有谁知道如何解决这个问题？

Does anyone know how to fix this?

推荐答案

如果您正在使用的CyanogenMod setMobileDataEnabled方法（布尔）在setMobileDataEnabled（字符串，布尔）改变......你可以看到在这条线上code 的。

If you are using cyanogenmod the method setMobileDataEnabled(boolean) is changed in setMobileDataEnabled(String, boolean)...as you can see on this line of code.

所以，你可以用标准的方式，然后在NoSuchMethodException catch块尝试的CyanogenMod的方式是这样的：

So you can use the standard way and then in the NoSuchMethodException catch block try the "cyanogenmod" way like this:

Class[] cArg = new Class[2];
cArg[0] = String.class;
cArg[1] = Boolean.TYPE;
Method setMobileDataEnabledMethod;

setMobileDataEnabledMethod = iConnectivityManagerClass.getDeclaredMethod("setMobileDataEnabled", cArg);

Object[] pArg = new Object[2];
pArg[0] = getContext().getPackageName();
pArg[1] = true;
setMobileDataEnabledMethod.setAccessible(true);
setMobileDataEnabledMethod.invoke(iConnectivityManager, pArg);

我不知道其他器官功能障碍综合征的影响。

I don't know if other mods are affected.
