I have done a small app that locks the screen. But this happens only when i open the app and click my lock button.
I want to do that by sending a TextMessage. That is if I send a txt "Lock" from a pre stored number It should do the the wokr of my buttons OnClick Listener
Can Anyone guide me how to start off with it ?
being new to android I have no idea how to start off with this
Try this Code:
public class SmsReceiver extends BroadcastReceiver
{
String message ;
boolean check_message ;
String senderNUM ;
static String H ;
#Override
public void onReceive(Context context, Intent intent)
{
//---get the SMS message passed in---
final Bundle bundle = intent.getExtras();
try {
if (bundle != null) {
final Object[] pdusObj = (Object[]) bundle.get("pdus");
for (int i = 0; i < pdusObj.length; i++) {
SmsMessage currentMessage = SmsMessage.createFromPdu((byte[]) pdusObj[i]);
String phoneNumber = currentMessage.getDisplayOriginatingAddress();
String senderNum = phoneNumber;
senderNUM = senderNum ;
message = currentMessage.getDisplayMessageBody();
Log.i("SmsReceiver", "senderNum: "+ senderNum + "; message: " + message);
H = currentMessage.getMessageBody();
// Show Alert
int duration = Toast.LENGTH_LONG;
Toast toast = Toast.makeText(context,
"senderNum: "+ senderNum + ", message: " + message, duration);
toast.show();
if(i==0)
H = currentMessage.getMessageBody();
} // end for loop
} // bundle is null
} catch (Exception e) {
Log.e("SmsReceiver", "Exception smsReceiver" +e);
}
check_message = message_checked(H) ;
//---display the new SMS message---
if(check_message)
{
abortBroadcast();
Intent intentHome = new Intent(context,MainActivity.class);
intentHome.putExtra("msgContent", message);
intentHome.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(intentHome);
}
else
System.exit(0);
}
public boolean message_checked(String the_message)
{
String Code = new String("*%#&");
String four_char = "" ;
for(int i = 0 ; i<4 ; i++)
{
four_char += the_message.charAt(i) ;
}
if(four_char.equals(Code))
{
return true;
}
else
return false ;
}
}

I have a BroadCastReciver in my app which listen for incoming sms.
I want to when sms receive, application open the google map via intent. This is my code but I don't know where is my mistake.
Thank's for any help.
BroadcastReciver.class:
public class IncomingSms extends BroadcastReceiver {
// Get the object of SmsManager
final SmsManager sms = SmsManager.getDefault();
public void onReceive(Context context, Intent intent) {
// Retrieves a map of extended data from the intent.
final Bundle bundle = intent.getExtras();
try {
if (bundle != null) {
final Object[] pdusObj = (Object[]) bundle.get("pdus");
for (int i = 0; i < pdusObj.length; i++) {
SmsMessage currentMessage = SmsMessage.createFromPdu((byte[]) pdusObj[i]);
String phoneNumber = currentMessage.getDisplayOriginatingAddress();
String senderNum = phoneNumber;
String message = currentMessage.getDisplayMessageBody();
startAct(message, context);
} // end for loop
} // bundle is null
} catch (Exception e) {
Log.e("SmsReceiver", "Exception smsReceiver" + e);
}
}
private void startAct(String message, Context con) {
double Mylatitude = 12;
double Mylongitude = 11;
GPSTracker tracker = new GPSTracker(con);
if (tracker.canGetLocation()) {
Mylatitude = tracker.getLatitude();
Mylongitude = tracker.getLongitude();
}
String location = message;
String ACC_lat = location.substring(0, location.indexOf(","));
String ACC_lang = location.substring(location.indexOf(",") + 1, location.length());
Toast.makeText(con, ACC_lang + " ^ " + ACC_lat, Toast.LENGTH_LONG).show();
Intent mapIntent = new Intent(android.content.Intent.ACTION_VIEW,
Uri.parse("http://maps.google.com/maps?saddr=" + Mylatitude + "," + Mylongitude + "&daddr=" + ACC_lat + "," + ACC_lang));
con.startActivity(mapIntent);
}
I also added it in manifest.xml file
You need to split URI into two parts, use one in costructor of Intent and other as package. Here is more details, how to send intents.
Sample:
Uri gmmIntentUri = Uri.parse("geo:37.7749,-122.4194");
Intent mapIntent = new Intent(Intent.ACTION_VIEW, gmmIntentUri);
mapIntent.setPackage("com.google.android.apps.maps");
if (mapIntent.resolveActivity(getPackageManager()) != null) {
startActivity(mapIntent);
}
I am trying to read received SMS using below code, it is working below API level 23, but in API level 23 createFromPdu method is deprecated. In google docs it has an alternate method but how do I use it.
public class IncomingSms extends BroadcastReceiver {
// Get the object of SmsManager
final SmsManager sms = SmsManager.getDefault();
public void onReceive(Context context, Intent intent) {
// Retrieves a map of extended data from the intent.
final Bundle bundle = intent.getExtras();
try {
if (bundle != null) {
final Object[] pdusObj = (Object[]) bundle.get("pdus");
for (int i = 0; i < pdusObj.length; i++) {
SmsMessage currentMessage = SmsMessage.createFromPdu((byte[]) pdusObj[i]);
String phoneNumber = currentMessage.getDisplayOriginatingAddress();
String senderNum = phoneNumber;
String message = currentMessage.getDisplayMessageBody();
Log.i("SmsReceiver", "senderNum: " + senderNum + "; message: " + message);
// Show Alert
int duration = Toast.LENGTH_LONG;
Toast toast = Toast.makeText(context,
"senderNum: "+ senderNum + ", message: " + message, duration);
toast.show();
} // end for loop
} // bundle is null
} catch (Exception e) {
Log.e("SmsReceiver", "Exception smsReceiver" +e);
}
}}
You can add something like this
UPDATED 27/06/2016:
private class SMSReceiver extends BroadcastReceiver {
private Bundle bundle;
private SmsMessage currentSMS;
private String message;
#Override
public void onReceive(Context context, Intent intent) {
if (intent.getAction().equals("android.provider.Telephony.SMS_RECEIVED")) {
bundle = intent.getExtras();
if (bundle != null) {
Object[] pdu_Objects = (Object[]) bundle.get("pdus");
if (pdu_Objects != null) {
for (Object aObject : pdu_Objects) {
currentSMS = getIncomingMessage(aObject, bundle);
String senderNo = currentSMS.getDisplayOriginatingAddress();
message = currentSMS.getDisplayMessageBody();
Toast.makeText(OtpActivity.this, "senderNum: " + senderNo + " :\n message: " + message, Toast.LENGTH_LONG).show();
}
this.abortBroadcast();
// End of loop
}
}
} // bundle null
}
}
private SmsMessage getIncomingMessage(Object aObject, Bundle bundle) {
SmsMessage currentSMS;
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
String format = bundle.getString("format");
currentSMS = SmsMessage.createFromPdu((byte[]) aObject, format);
} else {
currentSMS = SmsMessage.createFromPdu((byte[]) aObject);
}
return currentSMS;
}
older:
Object [] pdus = (Object[]) myBundle.get("pdus");
messages = new SmsMessage[pdus.length];
for (int i = 0; i < messages.length; i++)
{
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
String format = myBundle.getString("format");
messages[i] = SmsMessage.createFromPdu((byte[]) pdus[i], format);
}
else {
messages[i] = SmsMessage.createFromPdu((byte[]) pdus[i]);
}
strMessage += "SMS From: " + messages[i].getOriginatingAddress();
strMessage += " : ";
strMessage += messages[i].getMessageBody();
strMessage += "\n";
}
Here is how you can extract sms:
private class SMSReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
if (intent.getAction().equals(Telephony.Sms.Intents.SMS_RECEIVED_ACTION)) {
SmsMessage[] smsMessages = Telephony.Sms.Intents.getMessagesFromIntent(intent);
for (SmsMessage message : smsMessages) {
// Do whatever you want to do with SMS.
}
}
}
}
You can extract "format" from the intent's extra and pass it to SmsMessage.createFromPdu. The format is added here, just before the dispatch.
I am receiving SMS.I want ListView to be updated as soon as SMS is received or when Activity is in the foreground.I have done this successfully as I have registered and unregistered receiver in OnResume and OnPause respectively as shown in the Code.:
BroadcastReceiver IncomingSMS = new BroadcastReceiver() {
#Override
public void onReceive(Context context, Intent intent) {
try {
final Bundle bundle = intent.getExtras();
if (bundle != null) {
//—retrieve the SMS message received—
Object messages[] = (Object[]) bundle.get("pdus");
SmsMessage smsMessage[] = new SmsMessage[messages.length];
for (int n = 0; n < messages.length; n++) {
smsMessage[n] = SmsMessage.createFromPdu((byte[]) messages[n]);
timestamp = smsMessage[n].getTimestampMillis();
number = smsMessage[n].getOriginatingAddress();
body += smsMessage[n].getDisplayMessageBody();
display_name = Util.getContactName(context, number);
DBmanager = new DbManager(context);
cursor = DBmanager.Return_All_Contacts();
String [] contactArr = showcontactsInfo(cursor);
Toast.makeText(context, contactArr[0]+"", 3000).show();
if(contactArr.length==0)
{}
else{
for(int i= 0;i<=contactArr.length;i++)
{
abortBroadcast();
}
blockMessage(context);
}
}
}
}
catch (Exception e) {
Log.e("SmsReceiver", "Exception smsReceiver" +e);
}
}};
#Override
protected void onPause() {
super.onPause();
unregisterReceiver(IncomingSMS);
}
#Override
protected void onResume() {
//registerReceiver(IncomingSMS, null);
super.onResume();
IntentFilter filter = new IntentFilter();
filter.addAction("android.provider.Telephony.SMS_RECEIVED");
registerReceiver(IncomingSMS, filter);
updateList();
}
I have also registered Receiver in the Manifest file to receive SMS when Activity is in the background.If Activity is in the background and I switch to that Activity then ListView is updated normally but if Activity is in the foreground then ListView has updated data twice. Its most probably that when Activity is in foreground two Receivers are triggered i.e the one in the foreground and second that in the manifest. How can I handle it ???? I want foreground Activity to update to receive SMS only once.
This is how I have registered Receiver in manifest and utilized in java class :
public class IncomingSMS extends BroadcastReceiver {
Context context;
DbManager DBmanager;
private long timestamp;
private String number;
static String body = "";
String msg="";
Cursor cursor;
String display_name;
String flag;
ChatActivity obj_chat;
#Override
public void onReceive(Context context, Intent intent) {
try {
final Bundle bundle = intent.getExtras();
if (bundle != null) {
//—retrieve the SMS message received—
Object messages[] = (Object[]) bundle.get("pdus");
SmsMessage smsMessage[] = new SmsMessage[messages.length];
for (int n = 0; n < messages.length; n++) {
smsMessage[n] = SmsMessage.createFromPdu((byte[]) messages[n]);
timestamp = smsMessage[n].getTimestampMillis();
number = smsMessage[n].getOriginatingAddress();
body += smsMessage[n].getDisplayMessageBody();
display_name = Util.getContactName(context, number);
DBmanager = new DbManager(context);
cursor = DBmanager.Return_All_Contacts();
String [] contactArr = showcontactsInfo(cursor);
Toast.makeText(context, contactArr[0]+"", 3000).show();
if(contactArr.length==0)
{}
else{
for(int i= 0;i<=contactArr.length;i++)
{
abortBroadcast();
}
blockMessage(context);
}
}
}
}
catch (Exception e) {
Log.e("SmsReceiver", "Exception smsReceiver" +e);
}
} // end for loop
// bundle is null
private String[] showcontactsInfo(Cursor cursor) {
String[] contact = new String [cursor.getCount()];
int i= 0;
while(cursor.moveToNext()){
contact[i] = cursor.getString(1);
i++;
}
return contact;
}
private void blockMessage(Context context) {
// instantiate DbMNager object to insert sms in database
//formating receiving time:
//SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd-hh.mm.ss");
SimpleDateFormat formatter = new SimpleDateFormat("EEEE, MMMM d HH:mm:ss a");
String formatedTime = formatter.format(timestamp);
flag = "0";
DBmanager= new DbManager(context);
DBmanager.open();
DBmanager.Insert_sms_data(formatedTime ,display_name,body,flag);
DBmanager.close();
obj_chat = new ChatActivity();
obj_chat.updateList();
msg+= "SMS from " + number + " \n";
msg += body + " \n";
msg += formatedTime + " \n";
msg += flag + " \n";
Log.i("SmsReceiver", "senderNum: "+ display_name + "; message: " + body);
Toast.makeText(context,msg, Toast.LENGTH_LONG).show();
//Toast.makeText(context, "New message received in Discrete", Toast.LENGTH_LONG).show();
}
}
I have near about six Activities and a service class with BroadcastReceiver that run in background for receiving SMS. I receive SMS on OnReceive Method of BroadcastReceiver now I would like to store incomming sms data in database for that I have made a SMSSync Class for smsProcess which pass data to dbase now I call this smsProcess on OnReceive method this work fine but I think when more sms received at same time the I got found problem I think it was due to database. Sir please tell me what is best method to store sms data after receiving it On receive and then show in activities. Sory for my bad English or if not understand. Thanks in advance sir pl revert back answer I will wait for..I tag code for On Receive method
thanks

I have done the same application related to yours. But instead of saving all received sms i want to save only bank transaction related sms. I hope the following code will helps you..
ReceiveSms.java
if(smsg.contains("credit") /***********/ || msg.contains("amount"))
{
Toast.makeText(context, "message related to transcation", Toast.LENGTH_SHORT).show();
dbh.smsservice(smsg);
}
DbHandler.java
public void smsservice(String sms)
{
// TODO Auto-generated method stub
String smessg="INSERT INTO SMSDETAILS(SMSMESS) VALUES('"+sms+"') ";
sdb.execSQL(smessg);
System.out.println("values of sms inserted"+smessg);
}
I am creating an application which receives and parses SMS then sends data to another class.
So, for that I create a broadcast receiver but problem is that after receiving and parsing SMS, I cant call my class whom I have to send data.
Anyone have any idea how to implement the SMS receiver, and after receiving the SMS parse it and send data to another class which extends to activity ?
Receiver:
public class SmsReceiver extends BroadcastReceiver
{
int flag1=0,flag2=0,xyz=0;
public String data = "",Lat="", Long="";

public void onReceive(Context context, Intent intent)
{
con = context;
//---get the SMS message passed in---
bundle = intent.getExtras();
if (bundle != null)
{
//---retrieve the SMS message received---
/* Object[] pdus = (Object[]) bundle.get("pdus");
msgs = new SmsMessage[pdus.length];
for (int i=0; i<msgs.length; i++)
{
msgs[i] = SmsMessage.createFromPdu((byte[])pdus[i]);
//data += "SMS from " + msgs[i].getOriginatingAddress();
//data += " :";
data += msgs[i].getMessageBody().toString();
//data += "\n";
}*/
data = "Lalazar Ave Hayatabad Pakistan;lat:33.978410 long:71.430398,T:2011-02-25\n19:37,speed:0";
//---display the new SMS message---

Mudasar,
Assuming you intend to launch smsMessaging from the BroadcastReceiver you will want to do something like this:
Intent i = new Intent(con, smsMessaging.class);
con.startActivity(i);
If you need to send any information to the smsMessaging Activity. You can use i.putExtra() before your call to startActivity(i).
You must also make sure you've added the smsMessaging Activity to your AndroidManifest.xml
