Android :: Unable To Get Data From Activity To Service / How Intents Could Pass That?
Nov 24, 2010I am pretty new to this but I was told I could get good help here. A friend and myself are playing around with creating Android apps (using ADT)
Here is how we are trying to make the program: in activity, user sets threshold values for the X and Y axis on accelerometer. When user hits button "Start", startService is invoked and starts TiltService.
TiltService is designed to run in the background always on the phone without user interaction. TiltService constantly compares the threshold with the accelerometer values and will vibrate if they are off.
My problem is I can't seem to get the putExtra() data correctly. I have overridden the onStartCommand in my service but I get the message "unreachable code" when I save the getExtras() to a bundle.
Here is the relevant code (I can post the whole thing, just do not want to clog up page) code...
I thought I understood the basic of how Intents could pass data, but I guess I don't. Is it obvious what I am missing?
Android :: How To Pass An Object To An Activity Via Intent.putExtra?
Aug 7, 2009I am developing an app that connects to a server. For that connection I created a class Client that maintains info about the connection . My app consists of several Activities and each of that Activity needs access to the Client object to communicate to the server. 1) Can I put somewhere the Client object so that all Acitvities have an access to it? 2) If not I would probably need to pass the object to each Activity via Intent.putExtra(). But putExtra doesn't accept Object as an argument. It only accepts several types like int, long, String etc. So how can I pass an object to another Activity?

How do I get this Intent in MyClient? Running this code triggers onResume() in MyClient, but because it's already running, calling getIntent() returns the Intent that initially created MyClient, which is always android.intent.action.MAIN
Android :: Pass Enumerators To An Activity Constructor From An Intent?
May 14, 2010I have an activity that when started needs access to two different ArrayLists. Both Lists are different Objects I have created myself.
Basically I need a way to pass these objects to the activity from an Intent. I can use addExtras() but this requires a Parceable compatible class. I could make my classes to be passed serializable but as I understand this slows down the program.
What are my options?
Can I pass an Enum?
As an an aside: is there a way to pass parameters to an Activity Constructor from an Intent?

View 5 Replies View RelatedAndroid :: Pass Data Through New Activity?
Jun 29, 2010In my Android app,I start a new activity with startActivityForResult(). I get the result in onActivityResult() perfectly. My problem is that there is a small bit of data that I know before I start the activity and I need that value to be available in onActivityResult(), too. I tried attaching it to my intent as an extra, but it wasn't attached to the intent that is available when the activity returns the result. I made it work by storing the data in a global variable, but I really don't like that approach. Is there a better, right way to pass data through an activity (instead of just to it)?

Android :: How To Pass Complex Data Structures Between Service And Remote Binder?
Feb 17, 2010The object passing between an Android service and the remote binder is happening through serialization of the object. If the service needs to return a very large collection, it seems very inefficient to use this. What is the recommended way to deal with this?

View 1 Replies View RelatedAndroid :: Pass Data From BroadcastReceiver Through To Activity Being Started?
Apr 11, 2010I've got an Android application which needs to be woken up sporadically throughout the day.To do this, I'm using the AlarmManager to set up a PendingIntent and have this trigger a BroadcastReceiver. This BroadcastReceiver then starts an Activity to bring the UI to the foreground.All of the above seems to work, in that the Activity launches itself correctly; but I'd like the BroadcastReceiver to notify the Activity that it was started by the alarm (as opposed to being started by the user). To do this I'm trying, from the onReceive() method of the BroadcastReceiver to set a variable in the extras bundle of the intent,Can anyone tell me what's different about passing a bundle from a BroadcastReceiver to an Activity, as opposed to passing the bundle from an Activity to a BroadcastReceiver?

View 1 Replies View RelatedAndroid :: Adding Data To Intent Fails To Load Activity
Apr 11, 2010I have a widget that supposed to call an Activity of the main app when the user clicks on widget body. My setup works for a single widget instance but for a second instance of the same widget the PendingIntent gets reused and as result the vital information that I'm sending as extra gets overwritten for the 1st instance. So I figured that I should pass widget ID as Intent data however as soon as I add Intent#setData I would see in the log that 2 separate Intents are appropriately fired but the Activity fails to pick it up so basically Activity will not come up and nothing happens (no error or warning ether)

Android :: Passing Data Between Service And Activity
Sep 19, 2010So I'm getting really confused on how to do this whole thing and I was hoping someone could break it down for me a little bit.I have a service that should always be running, and at certain times it needs to alert the user that a task is to be completed(probably through a notification bar icon). When the user accepts the task, the service needs to look into the local database, construct some non primitive objects, and give them to the activity that it just started.I have looked all over and gotten very confused as to a proper approach so I have a few questions to help me wrap my head around it.If an activity creates a local SQLite database can the service and activities of that application access that same database later?Does the service and activity need to be in the same or separate packages? I would think no but for some reason I remember seeing something about this elsewhere.
How would I do the data transmission from the service to the activity? I was thinking a content provider but it seems like there should be an easier way for the service to just hand off the data. Similar to an Intent but for non primitives.
Android :: Best Way To Share Data Between Service S And Activity A?
Jun 17, 2010I want to create an app that contains a Service S and an Activity A. The Service S is responsible for preprocessing, such as preparing the data shown on the UI of the Activity A, before the Activity A gets invoked.I want to be able to invoke the Service S from outside the package, say from another Android app's Activity class B, do the preprocessing, and then when the data is ready, invoke Activity A. What is the best way to share data between the Service S and Activity A?How can the external activity B communicate with the Service S to determine if it has completed with all its preprocessing, and the Activity A is ready to be invoked?
View 1 Replies View RelatedAndroid :: Use Of Intents Used For Sending Data To Activity From Service
Feb 16, 2010I am little confused with the use of intents used for sending data to activity from service. In my application I have to have startactivity from the service and have to pass data ,so that activity can utilize the data while launching.For this i have written the following code Intent intent = new Intent(Service.this,Activity.class); intent.putExtra("data", data); intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); context.start Activity(); I assume that the data is passed to the activity and can be parsed on the oncreate function of the activity.Now the service running in the background has to pass data to the activity continously for UI updates.For this I have written the following codeIntent intent = new Intent(Service.this, Activity.class); intent.putExtra("Data", data); intent.setAction(Intent.ACTION_ATTACH_DATA); sendBroadcast(intent,null); (Do I need to broadcast the intent???) In activity I have done following things:- Implemented broadcast reciever:private BroadcastReceiver mBroadcastReceiver = new BroadcastReceiver() { @Override public void onReceive(Context context, Intent intent) { if (Intent.ACTION_ATTACH_DATA.equals(intent.getAction())) { Bundle extra = intent.getExtras(); float Data[] = extra.getFloatArray("Data"); update(Data);
View 4 Replies View RelatedAndroid :: Sending Data Back And Forth Between Activity And Service Locally?
Aug 13, 2010I am a bit new to Android. What I need to do is send data back and forth between an activity and a service locally. The information sent is sensitive and must not be able to be picked up by other apps. This excludes using broadcast and the onBind() function if I understand things correctly? So the activity needs to send some string parameters to the service. Also it somehow needs to tell the service which activity started it so the service can reply to the correct class since many different activities will use this service.
Once the service has fetched the information via a http request it is suppose to send that data (just a long string which will later be parsed) back to the activity that started it. How do I go about doing this? Using static variables/functions is not an option since again many actives will be using this service. Sure it would be possible to use a static array to hold the classes but that just seems ugly. It's only possible to send simple variables (not objects) via the intent? There must be a better way to do this.
