How to update edittext from IntentService class?

I'm making a chat app and using intent service for sending messages to firebase database even after activity is destroyed. When the uploading is successful i want to clear text in Edittext in the IntentService class but don't know how to do it.
Acivity class code
Intent sendmsgService = new Intent(getApplicationContext(),SendMessageService.class);
sendmsgService.putExtra("msg",message);
sendmsgService.putExtra("time",time);
sendmsgService.putExtra("cuser",current_user);
sendmsgService.putExtra("otheruser",otherusername);
startService(sendmsgService);
IntentService class code
public class SendMessageService extends IntentService {
DatabaseReference msgDatabase , mDatabase;
String current_user,otherusername,message,time;
public SendMessageService() {
super("SendMessageService");
mDatabase = FirebaseDatabase.getInstance().getReference();
msgDatabase = mDatabase.child("messages").child(current_user).child(otherusername);
}
#Override
protected void onHandleIntent(#Nullable Intent intent) {
assert intent!=null;
message = intent.getStringExtra("msg");
time = intent.getStringExtra("time");
current_user = intent.getStringExtra("cuser");
otherusername = intent.getStringExtra("otheruser");
DatabaseReference push_database = msgDatabase.push();
String msg_push = push_database.getKey();
DatabaseReference d = FirebaseDatabase.getInstance().getReference();
String cuser = current_user+"/"+otherusername+"/";
String ouser = otherusername+"/"+current_user+"/";
Map<String,Object> chatitems = new HashMap<>();
chatitems.put("seen",false);
chatitems.put("msg",message);
chatitems.put("from",current_user);
Map<String,Object> msgitemmap = new HashMap<>();
chatitems.put("time", ServerValue.TIMESTAMP);
msgitemmap.put("servertime",ServerValue.TIMESTAMP);
msgitemmap.put("time",time);
msgitemmap.put("msg",message);
msgitemmap.put("from",current_user);
msgitemmap.put("to",otherusername);
msgitemmap.put("seen",false);
msgitemmap.put("key",msg_push);
Map<String,Object> chatmap = new HashMap<>();
chatmap.put("chatlist/"+cuser,chatitems);
chatmap.put("chatlist/"+ouser,chatitems);
chatmap.put("messages/"+cuser+msg_push,msgitemmap);
chatmap.put("messages/"+ouser+msg_push,msgitemmap);
d.updateChildren(chatmap).addOnSuccessListener(new OnSuccessListener<Void>() {
#Override
public void onSuccess(Void aVoid) {
//Here i want to clear the edittext
}
});
}}
If any other solution please suggest.

Intent service runs on background thread not on main(UI) thread but we can use the Handler mechanism to send/update data to activity.
To send data to activity you need to declare handler in your activity like:
Handler handler = new Handler() {
#Override
public void handleMessage(Message msg) {
Bundle reply = msg.getData();
// do whatever with the bundle here
}
};
in the intent service class pass data in this way:
Bundle bundle = intent.getExtras();
if (bundle != null) {
Messenger messenger = (Messenger) bundle.get("messenger");
Message msg = Message.obtain();
msg.setData(data); //put the data here
try {
messenger.send(msg);
} catch (RemoteException e) {
Log.i("error", "error");
}
}
Most Important invoke the intent service from activity to pass handler to it:
Intent intent = new Intent(this, IntentService1.class);
intent.putExtra("messenger", new Messenger(handler));
startService(intent);
Hope this will help you

Simple solution is to use Broadcast Reciever Declare this in your activity class
BroadcastReceiver broadCastNewMessage = new BroadcastReceiver() {
#Override
public void onReceive(Context context, Intent intent) {
// do your stuff here
edittext.setText("");
}
};
Now in onCreate() register this
registerReceiver(this.broadCastNewMessage, new IntentFilter("uploading_done"));
And in onDestroy()
unregisterReceiver(broadCastNewMessage);
Now Call this method from the service class where u want to update the activity
sendBroadcast(new Intent().setAction("uploading_done"));

How can I check whether response is came within one minute after sending SMS in android?

I am creating an application in which I am sending SMS automatically on button click.When SMS is sent I get a response from server in form of SMS.I read that message and perform task on it. Now problem is that when I receive SMS I want to consider only messages received within one minute after button click. What to do.?
public class IncomingSms extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent)
{
Global mApplication = ((Global)context.getApplicationContext());
String getPPN=mApplication.getPPN();
String getStatus=mApplication.getvStatus();
String ClientId=mApplication.getvClientId();
String MobileNo=mApplication.getvStrMobile();
String LocationId=mApplication.getVstrLocation();
String IMEI=mApplication.getVstrIMEI();
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();
mApplication.setvSenderNumber(senderNum);
mApplication.setvMessageBody(message);
String IsBroadCast=mApplication.getvAuthenticatedUser();
try
{
if(IsBroadCast=="1")
{
context.sendBroadcast(new Intent("Message_Recived"));
}
}
catch(Exception e){}
}
}
} catch (Exception e)
{
}
}
}
This class is called when SMS received and take me to Arming Activity's on receive method.
But I need that..Broadcast receiver only receive message only within 1 minute after sendinf SMS
ArmingActivity:
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_arming);
registerReceiver(broadcastReceiver, new IntentFilter("Message_Recived"));}
BroadcastReceiver broadcastReceiver = new BroadcastReceiver() {
#Override
public void onReceive(Context context, Intent intent) {
// internet lost alert dialog method call from here...
// if(strPPN.equals())
Global globalVariable = (Global) getApplicationContext();
String vvSenderNumber=globalVariable.getvSenderNumber();
String vvMessageBody=globalVariable.getvMessageBody();
String vvPPN=strPPN;
};
public void sendSms(String PPN, String smsBody) {
try {
SmsManager smsManager = SmsManager.getDefault();
smsManager.sendTextMessage(PPN, null, smsBody, null, null);
} catch (Exception e) {
e.printStackTrace();
}
}
if (strActionText.equals("1"))
{
sendSms(strPPN, MsgBody);
}
Here when send SMS start Broadcast receiver to start receiving SMS for 1 minute.
What to do?

you can do this with the Handler
for that start/register receiver and also start the Handler for the one minute
//start your broadcast here.
new Handler().postDelayed(new Runnable() {
#Override
public void run() {
// write code to stop/unregister receiver.
}
}, 60*1000);
for further display time you can use CountDownTimer class.

Android: pass variables from Activity to BroadcastReceiver

I have some problem with passing throught my variable from Activity to the BroadcastReceiver...
Here is my code:
here is my Broadcast receiver code... I try to catch SMS from one phone number which I have got from my Activity...
public class SMSMonitor extends BroadcastReceiver
{
private static final String ACTION = "android.provider.Telephony.SMS_RECEIVED";
public static String phone_number = "";
public static String msg_body = "";
public static final String SMS_EXTRA_NAME = "pdus";
#Override
public void onReceive(Context context, Intent intent)
{
String phone = intent.getExtras().getString("trusted_num");
if (intent != null && intent.getAction() != null && ACTION.compareToIgnoreCase(intent.getAction()) == 0)
{
Object[] pduArray = (Object[]) intent.getExtras().get("pdus");
SmsMessage[] messages = new SmsMessage[pduArray.length];
for (int i = 0; i < pduArray.length; i++)
{
messages[i] = SmsMessage.createFromPdu((byte[]) pduArray[i]);
}
phone_number = messages[0].getDisplayOriginatingAddress();
msg_body = messages[0].getMessageBody();
System.out.println("Phone number: "+phone_number);
System.out.println("Phone entered: "+phone);
}
}
}
Here is my Activity code:
public class Settings extends Activity implements OnClickListener{
private Button btn_save;
private EditText txt_phone;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_settings);
//set Save button
btn_save = (Button)findViewById(R.id.btn_save);
txt_phone = (EditText)findViewById(R.id.et_phone);
btn_save.setOnClickListener(this);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.activity_settings, menu);
return true;
}
#Override
public void onClick(View v)
{
if (v == btn_save)
{
try
{
String phone_num = txt_phone.getText().toString();
Intent i = new Intent(Settings.this, SMSMonitor.class);
i.putExtra("trusted_num", phone_num);
sendBroadcast(i);
}
catch(Exception e)
{
System.out.println("Error: "+e.getLocalizedMessage());
}
}
}
}
In this code I have text field for entering the phone number, which I need to pass to the BroadcastReceiver with intent.putExtra() method, but in LogCat I see, that variable didnot pass:
07-25 18:43:57.382: I/System.out(14245): Phone number: +37129690449
07-25 18:43:57.382: I/System.out(14245): Phone entered: null
So what I am doing wrong here?
UPD
Maybe code is not correct, but it works for me...
public void onReceive(Context context, Intent intent)
{
phone = intent.getExtras().getString("trusted_num");//get trusted phone number from Settings screen
//receive SMS
if (intent != null && intent.getAction() != null && ACTION.compareToIgnoreCase(intent.getAction()) == 0)
{
Object[] pduArray = (Object[]) intent.getExtras().get("pdus");
SmsMessage[] messages = new SmsMessage[pduArray.length];
for (int i = 0; i < pduArray.length; i++)
{
messages[i] = SmsMessage.createFromPdu((byte[]) pduArray[i]);
}
phone_number = messages[0].getDisplayOriginatingAddress();
msg_body = messages[0].getMessageBody();
System.out.println("Phone number: "+phone_number);
}
//check if number is not null
if (phone != null && phone != "")
{
System.out.println("Phone entered: "+phone);
}
}
}

You can't pass an intent to a broadcast receiver. "There is no way for a BroadcastReceiver to see or capture Intents used with startActivity()"
https://developer.android.com/reference/android/content/BroadcastReceiver.html
I had a similar issue a while back and solved it by using a combination of IntentServices and Activities. You have to restructure your program to fit these guidlines

Well, there are some things not that don't match:
You're sending an intent with no action in the first place, but you're specifying Broadcastreceiver's class; don't do like that:
Intent i = new Intent(Settings.this, SMSMonitor.class);
i.putExtra("trusted_num", phone_num);
sendBroadcast(i);
But try instead:
Intent i = new Intent("my_package_name.Some_general_constant");
i.putExtra("trusted_num", phone_num);
sendBroadcast(i);
Then, your BroadcastReceiver is supposed to know that it can also handle "Some_general_constant" action. For this reason, register an extra action in your Manifest file for your SMSMonitor:
<receiver android:name=".package_to_bla_bla.SMSMonitor">
<intent-filter>
<action android:name="my_package_name.Some_general_constant"/>
</intent-filter>
</receiver>
Then in your SMSMonitor you need to add an else if statement to handle this broadcast:
else if("my_package_name.Some_general_constant".equals(intent.getAction())
{
// get the data from intent and use it
}

Android - how to use broadcast receiver to read SMS?

In my android project I need to detect and read SMS texts as they come in, then call a function from another class.
How can I put the below code in a class and define it properly in the manifest. If I put this on another Java file, then I don't know how to call a function from another Java file.
I tried putting this code in my main class but in my app, it just crashed.
public class SMSReceiverActivity extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
// Parse the SMS.
Bundle bundle = intent.getExtras();
SmsMessage[] msgs = null;
String str = "";
if (bundle != null)
{
// Retrieve the SMS.
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]);
// In case of a particular App / Service.
//if(msgs[i].getOriginatingAddress().equals("+91XXX"))
//{
//str += "SMS from " + msgs[i].getOriginatingAddress();
//str += " :";
str += msgs[i].getMessageBody().toString();
str += "\n";
//}
}
if (str != "") { // remove the last \n
str = str.substring(0, str.length()-1);
}
Reusable_CodeActivity.alert(my_ViewActivity.this, "AAAAAAAAAAA");
try {
//my_ViewActivity.this.handle_incoming_message(str);
} catch(Exception e) {
}
}
}
}

Your code for receiving SMS is correct. but when you are using BroadCastReceiver in Activity class you need to unregister it as follows in onStop() method. I think this is the reason your activity was crushing.
#Override
protected void onStop()
{
unregisterReceiver(mReceiver);
super.onStop();
}

If I understand your question correctly you want to receive broadcasts (when an SMS arrives) while your Activity is showing.
If so I found a nice pattern to do this a while back (Cant remember where I got it from, would be nice to give credit to the original author).
First, create an interface:
public interface Receiver {
public void onReceive(Context context, Intent intent);
}
Now create a subclass of BroadcastReceiver which we can dynamically register at runtime:
public class PortableReceiver extends BroadcastReceiver {
private Receiver mReceiver;
public void setReceiver(Receiver receiver) {
mReceiver = receiver;
}
public Receiver getReceiver() {
return mReceiver;
}
#Override
public void onReceive(Context context, Intent intent) {
if (mReceiver != null)
mReceiver.onReceive(context, intent);
else
Log.w("PortableReceiver", "Dropping received Result");
}
}
Now we can use a PortableReceiver in the activity class:
public class MyActivity implements Receiver {
private PortableReceiver mReceiver;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
mReceiver = new PortableReceiver();
mReceiver.setReceiver(this);
}
#Override
public void onResume() {
super.onResume();
// Register the receiver
IntentFilter filter = new IntentFilter();
filter.addAction("_my_intent_action"); //TODO: add actions to filter just as you would in your AndroidManifest
registerReceiver(mReceiver, filter, null, null);
}
#Override
public void onPause() {
super.onPause();
unregisterReceiver(mReceiver);
}
#Override
public void onReceive(Context context, Intent intent) {
//TODO: Your code goes here!
}
}
Now you have your Activity class directly handling the Broadcast, so you can access all the functionality it has available.
Note that if you want to start an activity from a BroadcastReceiver, thats a little different. If thats the case, I recommend you check out http://www.vogella.com/articles/AndroidServices/article.html#pre_broadcastreceiver

Can't start an activity in application onCreate

I am trying to start an activity after n seconds with a handler. The application was crashing on the startActivity call, so I put the handler code in my application's onCreate, and it is still crashing (which makes me think that the error comes from me not using startActivity well) :
#Override
public void onCreate(){
String roomName = this.getSettingValue(R.string.PREFERENCES_ROOM_NAME, "");
Room room;
try {
room = this.getRoomWithName(roomName);
} catch (ReservatorException ex) {
Toast err = Toast.makeText(this, ex.getMessage(),
Toast.LENGTH_LONG);
err.show();
return;
}
Intent i = new Intent(this, RoomActivity.class);
i.putExtra("room", room);
this.startActivity(i);
}
Strange thing is that this work when called from a view, by using exactly the same code, but different context :
Intent i = new Intent(getContext(), RoomActivity.class);
// ...
I am pretty new to Android ... so there may be information missing in that question, or I might even be trying to do something completely stupid who knows ?
EDIT
Link to the stacktrace : http://pastebin.com/vh2QC3xz
EDIT2
Here is the handler version of my code (so what I am trying to do in the end) :
public class ReservatorApplication extends Application {
private GoToFavouriteRoom goToFavouriteRoomRunable;
class GoToFavouriteRoom implements Runnable {
ReservatorApplication app;
public GoToFavouriteRoom(ReservatorApplication anApp){
app = anApp;
}
#Override
public void run() {
String roomName = app.getSettingValue(R.string.PREFERENCES_ROOM_NAME, "");
Room room;
try {
room = app.getDataProxy().getRoomWithName(roomName);
} catch (ReservatorException ex) {
Toast err = Toast.makeText(app, ex.getMessage(),
Toast.LENGTH_LONG);
err.show();
return;
}
RoomActivity.startWith(app, room);
}
}
private final ReservatorAppHandler handler = new ReservatorAppHandler();
class ReservatorAppHandler extends Handler{
#Override
public void handleMessage(Message msg){
return;
}
}
#Override
public void onCreate(){
String serverAddress = getSettingValue(R.string.PREFERENCES_SERVER_ADDRESS, "mail.futurice.com");// TODO: change to mail.futurice.com before delivery
proxy = new SoapDataProxy(serverAddress);
// proxy = new DummyDataProxy();
proxy = new CachedDataProxy(proxy);
addressBook = new FumAddressBook();
try {
addressBook.prefetchEntries();
} catch (ReservatorException e) {
// TODO: DIE!
}
goToFavouriteRoomRunable = new GoToFavouriteRoom(this);
handler.postDelayed(goToFavouriteRoomRunable, 20000);
}

Ok ... I finally solved my problem, mainly thanks to #Drax
Apparently, you just can't start an activity from an application ... you need an instance of an activity. So :
public class ReservatorApplication extends Application {
#Override
public void onCreate(){
Intent i = new Intent(this, RoomActivity.class);
this.startActivity(i);
}
}
Is just not valid, and causes a RunTimeException ...

As far as crashing is concern when you start activity in handler with "this". it will take handler's context. and when you do getContext() it will take activity context.

Intent i = new Intent(YourActivityName.this, RoomActivity.class);
or
Intent i = new Intent(getBaseContext(), RoomActivity.class);

It`s hard to answer without seeing the stack trace from logcat, but I found that sometimes you need to pass the application context to the a new Intent before starting an Activity.
Try this line:
Intent i = new Intent(getApplicationContext(), RoomActivity.class);
