问题
I was having one solution for enabling and disabling data that was working good in API 8 and 10, but that code was not compatible with the ICS, I need a global solution, so that the same code must be compatible from API 8 to till date Android OS versions.
回答1:
Use the following method. It'll work with all android versions.
int bv = Build.VERSION.SDK_INT;
boolean turnOnDataConnection(boolean ON,Context context)
{
try{
if(bv == Build.VERSION_CODES.FROYO)
{
Method dataConnSwitchmethod;
Class<?> telephonyManagerClass;
Object ITelephonyStub;
Class<?> ITelephonyClass;
TelephonyManager telephonyManager = (TelephonyManager) context
.getSystemService(Context.TELEPHONY_SERVICE);
telephonyManagerClass = Class.forName(telephonyManager.getClass().getName());
Method getITelephonyMethod = telephonyManagerClass.getDeclaredMethod("getITelephony");
getITelephonyMethod.setAccessible(true);
ITelephonyStub = getITelephonyMethod.invoke(telephonyManager);
ITelephonyClass = Class.forName(ITelephonyStub.getClass().getName());
if (ON) {
dataConnSwitchmethod = ITelephonyClass
.getDeclaredMethod("enableDataConnectivity");
} else {
dataConnSwitchmethod = ITelephonyClass
.getDeclaredMethod("disableDataConnectivity");
}
dataConnSwitchmethod.setAccessible(true);
dataConnSwitchmethod.invoke(ITelephonyStub);
}
else
{
//log.i("App running on Ginger bread+");
final ConnectivityManager conman = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
final Class<?> conmanClass = Class.forName(conman.getClass().getName());
final Field iConnectivityManagerField = conmanClass.getDeclaredField("mService");
iConnectivityManagerField.setAccessible(true);
final Object iConnectivityManager = iConnectivityManagerField.get(conman);
final Class<?> iConnectivityManagerClass = Class.forName(iConnectivityManager.getClass().getName());
final Method setMobileDataEnabledMethod = iConnectivityManagerClass.getDeclaredMethod("setMobileDataEnabled", Boolean.TYPE);
setMobileDataEnabledMethod.setAccessible(true);
setMobileDataEnabledMethod.invoke(iConnectivityManager, ON);
}
return true;
}catch(Exception e){
Log.e(TAG,"error turning on/off data");
return false;
}
}
Permissions Required:

<uses-permission android:name="android.permission.MODIFY_PHONE_STATE"/>
<uses-permission android:name="android.permission.READ_PHONE_STATE"/>
UPDATE:
Starting from Android L this works only for System applications
回答2:
This code running in android gingerbread and higher:
private void setMobileDataEnabled(Context context, boolean enabled) {
final ConnectivityManager conman = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
final Class conmanClass = Class.forName(conman.getClass().getName());
final Field iConnectivityManagerField = conmanClass.getDeclaredField("mService");
iConnectivityManagerField.setAccessible(true);
final Object iConnectivityManager = iConnectivityManagerField.get(conman);
final Class iConnectivityManagerClass = Class.forName(iConnectivityManager.getClass().getName());
final Method setMobileDataEnabledMethod = iConnectivityManagerClass.getDeclaredMethod("setMobileDataEnabled", Boolean.TYPE);
setMobileDataEnabledMethod.setAccessible(true);
setMobileDataEnabledMethod.invoke(iConnectivityManager, enabled);
}
NOTE: U MUST ADD THIS BELOW LINE IN ANDROIDMAINFEST.XML
<uses-permission android:name="android.permission.CHANGE_NETWORK_STATE"/>
回答3:
You also need that permission:
<uses-permission android:name="android.permission.MODIFY_PHONE_STATE"/>
回答4:
private static boolean enableMobileData(Context context, boolean enable) {
boolean bool = true;
ConnectivityManager cm = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
try {
Class[] arrayOfClass = new Class[1];
arrayOfClass[0] = Boolean.TYPE;
Method enableDataMethod = ConnectivityManager.class.getMethod("setMobileDataEnabled", arrayOfClass);
DailySchedulerLog.v("Method enableDataMethod = %s", enableDataMethod.getName());
Object[] arrayOfObject = new Object[1];
arrayOfObject[0] = Boolean.valueOf(enable);
enableDataMethod.invoke(cm, arrayOfObject);
return bool;
} catch (Exception localException) {
// while (true) {
DailySchedulerLog.d("Exception !!!!!!!!! loops");
return bool = false;
// }
}
}
this snipcode works with my case. Plz, add permissions related to change network
