您可以檢查它是否是通過使用下面的代碼
ConnectivityManager connManager = (ConnectivityManager) getSystemService(CONNECTIVITY_SERVICE);
NetworkInfo mMobile = connManager.getNetworkInfo(ConnectivityManager.TYPE_MOBILE);
if (mMobile.isConnected()) {
//if internet connected
}
,如果它被禁用啓用或禁用,則可以啓用它通過使用這一
void turnData(boolean ON) throws Exception
{
if(bv == Build.VERSION_CODES.FROYO)
{
Log.i("version:", "Found Froyo");
try{
Method dataConnSwitchmethod;
Class telephonyManagerClass;
Object ITelephonyStub;
Class ITelephonyClass;
TelephonyManager telephonyManager = (TelephonyManager) getApplicationContext().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);
}catch(Exception e){
Log.e("Error:",e.toString());
}
}
else
{
Log.i("version:", "Found Gingerbread+");
final ConnectivityManager conman = (ConnectivityManager) getApplicationContext().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);
}
,也是你的froyo
設備上,不要忘記把這些東西加到manifest
android.permission.UPDATE_DEVICE_STATS
android.permission.CHANGE_NETWORK_STATE
android.permission.ACCESS_NETWORK_STATE
android.permission.MODIFY_PHONE_STATE
android.permission.READ_PHONE_STATE
嗨,謝謝你的回答!這是完美的工作。其實,我有一個Manifest權限問題(android.permission.UPDATE_DEVICE_STATS&android.permission.MODIFY_PHONE_STATE)。我已經修復了這樣的:http://stackoverflow.com/questions/13801984/permission-is-only-granted-to-system-app。 – Split 2013-05-10 19:51:39
