我需要以编程方式打开/关闭移动数据.下面的代码不适用于5.x.你能帮我么.提前致谢.
private void setMobileDataEnabled(Context context,boolean enabled) throws ClassNotFoundException,NoSuchFieldException,IllegalAccessException,NoSuchMethodException,InvocationTargetException {
final ConnectivityManager conman = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
final Class conmanClass = Class.forName(conman.getClass().getName());
final Field connectivityManagerField = conmanClass.getDeclaredField("mService");
connectivityManagerField.setAccessible(true);
final Object connectivityManager = connectivityManagerField.get(conman);
final Class connectivityManagerClass = Class.forName(connectivityManager.getClass().getName());
final Method setMobileDataEnabledMethod = connectivityManagerClass.getDeclaredMethod("setMobileDataEnabled",Boolean.TYPE);
setMobileDataEnabledMethod.setAccessible(true);
setMobileDataEnabledMethod.invoke(connectivityManager,enabled); }
03-30 12:42:29.466: W/System.err(5966):
java.lang.NoSuchMethodException: setMobileDataEnabled [boolean] 03-30
12:42:29.466: W/System.err(5966): at
java.lang.Class.getMethod(Class.java:664) 03-30 12:42:29.466:

java.lang.Class.getDeclaredMethod(Class.java:626)
java.lang.NoSuchMethodException：setMobileDataEnabled [boolean] @在line下面.
final Method setMobileDataEnabledMethod =
connectivityManagerClass.getDeclaredMethod(“setMobileDataEnabled”,
Boolean.TYPE);
解决方法
It seems like the setMobileDataEnabled method no longer exists in
ConnectivityManager and this functionality was moved to
TelephonyManager with two methods getDataEnabled and setDataEnabled.
public void setMobileDataState(boolean mobileDataEnabled)
{
try
{
TelephonyManager telephonyService = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
Method setMobileDataEnabledMethod = telephonyService.getClass().getDeclaredMethod("setDataEnabled",boolean.class);
if (null != setMobileDataEnabledMethod)
{
setMobileDataEnabledMethod.invoke(telephonyService,mobileDataEnabled);
}
}
catch (Exception ex)
{
Log.e(TAG,"Error setting mobile data state",ex);
}
}
public boolean getMobileDataState()
{
try
{
TelephonyManager telephonyService = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
Method getMobileDataEnabledMethod = telephonyService.getClass().getDeclaredMethod("getDataEnabled");
if (null != getMobileDataEnabledMethod)
{
boolean mobileDataEnabled = (Boolean) getMobileDataEnabledMethod.invoke(telephonyService);
return mobileDataEnabled;
}
}
catch (Exception ex)
{
Log.e(TAG,"Error getting mobile data state",ex);
}
return false;
}
执行代码时,您会收到SecurityException,指出用户10089和当前进程都没有android.permission.MODIFY_PHONE_STATE.
