Para adicionar, remover e setar APNs, você precisa usar os ContentResolver para gerenciar a base de APNs no SO.
Fizemos uma abstração do seu uso com os snippets abaixo e, para usá-lo você precisa fazer como exemplo a seguir:
ApnHandler apnHandler = new ApnHandler(context);
ApnInfo apnInfo = new ApnInfo("OPERADORA", "operadora.com.br", "user", "password"))
boolean success = apnHandler.configureApn(apnInfo);| public class ApnHandler { | |
| private final static Uri APN_LIST_URI = Uri.parse("content://telephony/carriers"); | |
| private final static Uri PREFERRED_APN_URI = Uri.parse("content://telephony/carriers/preferapn"); | |
| private Context context; | |
| public ApnHandler(Context context) { | |
| this.context = context; | |
| } | |
| public boolean configureApn(ApnInfo apnInfo) { | |
| boolean ret; | |
| ContentValues contentValues; | |
| try { | |
| contentValues = NetworkUtils.getContentValuesForApnInfo(context, apnInfo); | |
| } catch (SimCardNotFoundException e) { | |
| e.printStackTrace(); | |
| return false; | |
| } | |
| ret = findApn(apnInfo.getApn()); | |
| if (!ret) { | |
| int apnId = addNewApn(context, contentValues); | |
| if (apnId != -1) { | |
| ret = setApn(apnId) == 1; | |
| } | |
| } | |
| return ret; | |
| } | |
| private int addNewApn(Context context, ContentValues contentValues) { | |
| int id = -1; | |
| ContentResolver contentResolver = context.getContentResolver(); | |
| Uri newUri = contentResolver.insert(APN_LIST_URI, contentValues); | |
| Cursor c = null; | |
| if (newUri != null) { | |
| c = contentResolver.query(newUri, null, null, null, null); | |
| int idIndex = c.getColumnIndex("_id"); | |
| c.moveToFirst(); | |
| id = c.getShort(idIndex); | |
| } | |
| if (c != null) { | |
| c.close(); | |
| } | |
| return id; | |
| } | |
| private int setApn(long id) { | |
| ContentResolver contentResolver = context.getContentResolver(); | |
| ContentValues contentValues = new ContentValues(); | |
| contentValues.put("apn_id", id); | |
| return contentResolver.update(PREFERRED_APN_URI, contentValues, null, null); | |
| } | |
| private boolean findApn(String name) { | |
| boolean found = false; | |
| String columns[] = new String[] { "_id", "apn"}; | |
| String where = "apn = ?"; | |
| String wargs[] = new String[] {name}; | |
| String sortOrder = null; | |
| Cursor cur = context.getContentResolver().query(APN_LIST_URI, columns, where, wargs, sortOrder); | |
| if (cur != null) { | |
| if (cur.moveToFirst()) { | |
| Log.d("ApnHandler", "APN " + cur.getString(1)); | |
| found = true; | |
| setApn(cur.getLong(0)); | |
| } | |
| cur.close(); | |
| } | |
| return found; | |
| } | |
| } |
| public class ApnInfo { | |
| private String carrierName; | |
| private String apn; | |
| private String user; | |
| private String password; | |
| public ApnInfo(String carrierName, String apn, String user, String password) { | |
| this.carrierName = carrierName; | |
| this.apn = apn; | |
