Utilice Content Resolver ( "content://sms/inbox" ) para leer los SMS que se encuentran en la bandeja de entrada.
// public static final String INBOX = "content://sms/inbox";
// public static final String SENT = "content://sms/sent";
// public static final String DRAFT = "content://sms/draft";
Cursor cursor = getContentResolver().query(Uri.parse("content://sms/inbox"), null, null, null, null);
if (cursor.moveToFirst()) { // must check the result to prevent exception
do {
String msgData = "";
for(int idx=0;idx<cursor.getColumnCount();idx++)
{
msgData += " " + cursor.getColumnName(idx) + ":" + cursor.getString(idx);
}
// use msgData
} while (cursor.moveToNext());
} else {
// empty box, no SMS
}
Agregue el permiso READ_SMS .
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
final String myPackageName = getPackageName();
if (!Telephony.Sms.getDefaultSmsPackage(this).equals(myPackageName)) {
Intent intent = new Intent(Telephony.Sms.Intents.ACTION_CHANGE_DEFAULT);
intent.putExtra(Telephony.Sms.Intents.EXTRA_PACKAGE_NAME, myPackageName);
startActivityForResult(intent, 1);
}else {
List<Sms> lst = getAllSms();
}
}else {
List<Sms> lst = getAllSms();
}
Configurar la aplicación como aplicación de SMS predeterminada
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == 1) {
if (resultCode == RESULT_OK) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
final String myPackageName = getPackageName();
if (Telephony.Sms.getDefaultSmsPackage(mActivity).equals(myPackageName)) {
List<Sms> lst = getAllSms();
}
}
}
}
}
Función para recibir SMS
public List<Sms> getAllSms() {
List<Sms> lstSms = new ArrayList<Sms>();
Sms objSms = new Sms();
Uri message = Uri.parse("content://sms/");
ContentResolver cr = mActivity.getContentResolver();
Cursor c = cr.query(message, null, null, null, null);
mActivity.startManagingCursor(c);
int totalSMS = c.getCount();
if (c.moveToFirst()) {
for (int i = 0; i < totalSMS; i++) {
objSms = new Sms();
objSms.setId(c.getString(c.getColumnIndexOrThrow("_id")));
objSms.setAddress(c.getString(c
.getColumnIndexOrThrow("address")));
objSms.setMsg(c.getString(c.getColumnIndexOrThrow("body")));
objSms.setReadState(c.getString(c.getColumnIndex("read")));
objSms.setTime(c.getString(c.getColumnIndexOrThrow("date")));
if (c.getString(c.getColumnIndexOrThrow("type")).contains("1")) {
objSms.setFolderName("inbox");
} else {
objSms.setFolderName("sent");
}
lstSms.add(objSms);
c.moveToNext();
}
}
// else {
// throw new RuntimeException("You have no SMS");
// }
c.close();
return lstSms;
}
La clase de SMS está a continuación:
public class Sms{
private String _id;
private String _address;
private String _msg;
private String _readState; //"0" for have not read sms and "1" for have read sms
private String _time;
private String _folderName;
public String getId(){
return _id;
}
public String getAddress(){
return _address;
}
public String getMsg(){
return _msg;
}
public String getReadState(){
return _readState;
}
public String getTime(){
return _time;
}
public String getFolderName(){
return _folderName;
}
public void setId(String id){
_id = id;
}
public void setAddress(String address){
_address = address;
}
public void setMsg(String msg){
_msg = msg;
}
public void setReadState(String readState){
_readState = readState;
}
public void setTime(String time){
_time = time;
}
public void setFolderName(String folderName){
_folderName = folderName;
}
}
No olvides definir el permiso en tu AndroidManifest.xml
<uses-permission android:name="android.permission.READ_SMS" />
Es un proceso trivial. Puedes ver un buen ejemplo en el código fuente SMSPopup.
Examina los siguientes métodos:
SmsMmsMessage getSmsDetails(Context context, long ignoreThreadId, boolean unreadOnly)
long findMessageId(Context context, long threadId, long _timestamp, int messageType
void setMessageRead(Context context, long messageId, int messageType)
void deleteMessage(Context context, long messageId, long threadId, int messageType)
este es el método para leer:
SmsMmsMessage getSmsDetails(Context context,
long ignoreThreadId, boolean unreadOnly)
{
String SMS_READ_COLUMN = "read";
String WHERE_CONDITION = unreadOnly ? SMS_READ_COLUMN + " = 0" : null;
String SORT_ORDER = "date DESC";
int count = 0;
// Log.v(WHERE_CONDITION);
if (ignoreThreadId > 0) {
// Log.v("Ignoring sms threadId = " + ignoreThreadId);
WHERE_CONDITION += " AND thread_id != " + ignoreThreadId;
}
Cursor cursor = context.getContentResolver().query(
SMS_INBOX_CONTENT_URI,
new String[] { "_id", "thread_id", "address", "person", "date", "body" },
WHERE_CONDITION,
null,
SORT_ORDER);
if (cursor != null) {
try {
count = cursor.getCount();
if (count > 0) {
cursor.moveToFirst();
// String[] columns = cursor.getColumnNames();
// for (int i=0; i<columns.length; i++) {
// Log.v("columns " + i + ": " + columns[i] + ": " + cursor.getString(i));
// }
long messageId = cursor.getLong(0);
long threadId = cursor.getLong(1);
String address = cursor.getString(2);
long contactId = cursor.getLong(3);
String contactId_string = String.valueOf(contactId);
long timestamp = cursor.getLong(4);
String body = cursor.getString(5);
if (!unreadOnly) {
count = 0;
}
SmsMmsMessage smsMessage = new SmsMmsMessage(context, address,
contactId_string, body, timestamp,
threadId, count, messageId, SmsMmsMessage.MESSAGE_TYPE_SMS);
return smsMessage;
}
} finally {
cursor.close();
}
}
return null;
}
Desde API 19 en adelante puedes hacer uso de la Clase de Telefonía para eso; Dado que los valores incondicionales no recuperarán mensajes en todos los dispositivos porque el proveedor de contenido Uri cambia según los dispositivos y fabricantes.
public void getAllSms(Context context) {
ContentResolver cr = context.getContentResolver();
Cursor c = cr.query(Telephony.Sms.CONTENT_URI, null, null, null, null);
int totalSMS = 0;
if (c != null) {
totalSMS = c.getCount();
if (c.moveToFirst()) {
for (int j = 0; j < totalSMS; j++) {
String smsDate = c.getString(c.getColumnIndexOrThrow(Telephony.Sms.DATE));
String number = c.getString(c.getColumnIndexOrThrow(Telephony.Sms.ADDRESS));
String body = c.getString(c.getColumnIndexOrThrow(Telephony.Sms.BODY));
Date dateFormat= new Date(Long.valueOf(smsDate));
String type;
switch (Integer.parseInt(c.getString(c.getColumnIndexOrThrow(Telephony.Sms.TYPE)))) {
case Telephony.Sms.MESSAGE_TYPE_INBOX:
type = "inbox";
break;
case Telephony.Sms.MESSAGE_TYPE_SENT:
type = "sent";
break;
case Telephony.Sms.MESSAGE_TYPE_OUTBOX:
type = "outbox";
break;
default:
break;
}
c.moveToNext();
}
}
c.close();
} else {
Toast.makeText(this, "No message to show!", Toast.LENGTH_SHORT).show();
}
}
