Hello On android API 20+ (previous API levels had the apn read blocked), I have a problem detecting the currently selected APN when the device changes it (when going to another country and changing from the current network to roaming). The preferapn does not change, it always return the same value:
Uri uri = Uri.parse("content://telephony/carriers/preferapn"); Cursor cursor = getContentResolver().query(uri, new String[] {Telephony.Carriers.APN}, null, null, Telephony.Carriers.DEFAULT_SORT_ORDER); if (null != cursor) { try { while (cursor.moveToNext()) { String apn = cursor.getString(cursor.getColumnIndexOrThrow(Telephony.Carriers.APN)); Log.d("APNs",apn); } } finally { cursor.close(); } } But if I manually go to the APN settings (Settings -> More -> Mobile networks -> Access point names), when I go back to the app, the returned value changes to the new value. The list of current APN is automatically changing, I don't have to go to the APN settings menu to get the changes, but querying the telephony/carriers or telephony/carriers/current I can't find a way to see the selected APN: Uri uri = Uri.parse("content://telephony/carriers/current"); Cursor cursor = getContentResolver().query(uri, new String[] {Telephony.Carriers.APN}, null, null, Telephony.Carriers.DEFAULT_SORT_ORDER); if (null != cursor) { try { while (cursor.moveToNext()) { String apn = cursor.getString(cursor.getColumnIndexOrThrow(Telephony.Carriers.APN)); Log.d("APNs",apn); } } finally { cursor.close(); } } Has anyone have a clue of why the preferapn isn't updating when the network changes? -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
