在Android 4.4.2上以编程方式切换移动数据

Question

我一直使用此代码以编程方式启用移动数据:

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);

这很好用,除了现在Android 4.4.2,我得到这个例外:

java.lang.NoSuchMethodException: setMobileDataEnabled [boolean]
    at  java.lang.Class.getConstructorOrMethod(Class.java:472)
    at java.lang.Class.getDeclaredMethod(Class.java:640)

    at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:597)
    at dalvik.system.NativeStart.main(Native Method)

有谁知道如何解决这一问题？

如果你正在使用cyanogenmod,那么方法setMobileDataEnabled(boolean)会在setMobileDataEnabled(String,boolean)中更改...正如你在这行代码中看到的那样.

所以你可以使用标准方式然后在NoSuchMethodException catch块中尝试像这样的"cyanogenmod"方式:

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mod是否会受到影响.
