I have a class that listens to SMS broadcast and, it then open an activity in the same application to display the message. This is part of a larger project.
Since the broadcast class does not extend the activity class, calling an Activity with intent requires that I flag it with Intent.FLAG_ACTIVITY_NEW_TASK.
Now the Intent has an extra (the SMS message and some parameters as a single string) which i want to send with the intent. All went well but the Extras are not sent with the intent.
Here are my code
From the broadcast class
//After getting the message into String S and doing some process
Intent inte = new Intent(context.getApplicationContext(), StartApp.class);
inte.putExtra("messageAsString", S.toString()); //Where S is declared somewhere
inte.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(inte);
From the activity recieving the Intent in the onCreate() method
if(getIntent().hasExtra("messageAsString")) {
String message = getIntent().getStringExtra("messageAsString").toString();
Toast toast = Toast.makeText(this, "Received SMS: " + message , Toast.LENGTH_LONG);
toast.show();
}
The application may have already running, the home button has been pressed. Either way, what I want to achieve is that as the registered reciever receives the message, I want to start an activity automatically and pass the message and its meta data to it.
I know I'm missing something somewhere but will appreciate your swift help
You also need to handle onNewIntent(), which may be called if the activity already exists and startActivity() brings an existing instance back to the foreground. Your extra is probably in there.

I have written an Application, which checks when you receive a new SMS and if its from a certain number, the app plays the ringtone. Now, the App should check if there is a new SMS even if it isn´t lauchned, and so my question is: How can I launch my App by receiving a new SMS?
I tryed to upload my existing code but it didn´t worked, I am sorry.
To start an activity from almost everywhere you can simply call:
Intent myIntent = new Intent(CurrentActivity.this, NewActivity.class);
CurrentActivity.this.startActivity(myIntent);
That should also work from your BroadcastReceiver which is triggered while receiving the sms.
I'm having a slightly different purpose, but, I think I'm putting it wrong as no one from multiple forums is able to answer it. The original question is here: Pass URL data from AppLink to WebView
Basically, suppose I'm creating a web browser app with a splash screen and I want to accept the URL intents from other apps, receive them in my splash screen, pass them on to my WebView activity and load it there, how can I do that?
For example, if a user has my app installed, and he/she taps https://www.google.com/ as a link in some app, how can I load the URL in my app after showing my splash screen? I think, the intent receiver will be in the splash screen activity, and the WebView is in another activity. So, basically, I want to receive the URL in my splash screen activity and then, pass it on to my WebView. How to achieve this?
I think what youre trying to do is to recieve data from other apps
That way, you can recieve data in a Splash Screen Activity and then show it in a Web View Activity
You can do this through putExtra method.
You can use intents, which are messages sent between activities. In an intent you can put all sort of data, String, int, etc.
In your case, in Splash Screen(say SplashActivity), before going to next activity(say MainActivity), you need to store a String message this way :
Intent intent = new Intent(SplashActivity.this, MainActivity.class);
intent.putExtra("message", message);
startActivity(intent);
In MainActivity, in onCreate(), you can get the String message by retrieving a Bundle (which contains all the messages sent by the calling activity) and call getString() on it :
Bundle bundle = getIntent().getExtras();
String message = bundle.getString("message");
Then you can use message variable as url.:
Hope this helps !
I always get bundle value null when I pass data from activity to broadcast receiver.
My receiver will start on boot up.
This is the code in my activity class
Intent intent= new Intent();
intent.setAction("android.intent.action.BOOT_COMPLETED");
intent.putExtra("test", "test");
sendBroadcast(intent);
This is the code in my receiver class:
String testValue = intent.getStringExtra("test");
Your code in activity will never be called upon booting up. System invokes onReceive() with its own intent. You can check this by putting some logs in activity code - this log will not be printed in logcat.
Here is the code snippet from our app now.
public void onClick(View v) {
// TODO Auto-generated method stub
Intent sms = new Intent(Intent.ACTION_VIEW, Uri.parse("sms:" ));
sms.putExtra("sms_body", text);
startActivity(sms);
}
This works with the stock SMS app, however a tester reported that with handcent SMS they get a blank message. This prompted me to try it with Google Voice, also get a blank message there.
Is there some way I can get my message text to work with all of these other SMS apps?
We have a clipboard functionality, so a poor workaround at least would be having user push clipboard button, then use their messaging app of choice.
Android tries to reuse Intents as much as possible. In some cases when you start an intent, android doesn't create a new Intent and reuse previous intents. To avoid this set this flag of Intent:
smsIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
This flag forces Android to create a new Task with the intent's Activity on top of stack.
When you pass this intent , this will be delivered to all those apps which have registered an activity to receive it. In otherwords you have to use the intent that is registered by the application that u intent to handle your intent
I can't find anything on this on google, nor here? But I am trying to create a notification and retrieve the value of an EditText field that has been set as a custom view for the notification
Is there anyway to retrieve this value? As notification's (as far as I'm aware) can just be set and/or updated.. but there must be some way!
That's not possible. The actual EditText view inside your notification is not even owned by your process - it's instantiated by the system using the RemoteViews object you are providing. The only way of communicating with it is by sending back predefined intents, for example via setOnClickPendingIntent. You cannot retrieve a content of EditText that way, though.
As a solution I'd recommend to display a dialog or activity with your EditText when user taps the notification, and handle their input there.
In your notification Intent
Intent notificationIntent = new Intent(this, FlightActivity.class);
Bundle bundle = new Bundle();
bundle.putString("whatever",YOUR_STRING_VALUE);
notificationIntent.putExtras(bundle);
When the application starts, you can get it using the intent
Is this what you want?
