I was just wondering if it is possible to give the intent a set of data, instead of just one. A particular scenario where this could be applicable would be a music application.You select a list of songs, and pass all these data (file path) to the Music Player's application.Another scenario: You need to plot more than one address on the Google Maps. You launch the application with a set of data for the intent.

I have an android context menu with various selections and depending on the user selection I want to start an intent. The intent starts the same activity for all the buttons but will contain different String variables depending on the selection. I am currently using a switch, case methodology for my click listener but keep running into 'duplicate local variable' problems as I try to eliminate code repetition! If anyone could provide a-bit of pseudo-code that would be even better.
View 3 Replies View RelatedI'm working on a project where I need to run the BroadcastReceiver for a third party library for a specific Intent. I also want to run some of my own code when the Intent is broadcast. If I supply my own BroadcastReceiver for the same Intent, it seems that only, one or the other runs, but not both, depending on which appears first in the AndroidManifest.xml file. Is it possible to register multiple BroadcastReceivers for the same Intent in the same application and have them all run? AndroidManifest.xml snippet
View 4 Replies View RelatedTrying to grok intents and actions in android and looking through the documentation. But one thing I keep seeing is an intent filter with multiple actions defined.
Like this, from the above link:
CODE:...........
But, if you call that activity, how does it choose which action is chosen?
For that matter, that linked to example has multiple activities that all contain the same actions, "android.intent.action.VIEW" for example. When calling this with something like content://com.google.provider.NotePad/notes how does it even know which activity to use?
In my application i have created pending intent which calls another activity (after 20mins of alarm off) with the help of alarm manger. It should happen each time for each new pending intent or when I call that activity. But when i create one pending intent and after few mins again create new pending intent ,then the last one overlap the other previous pending intents and start specified activity only for ones for the last pending intent.I want that each time i create any pending intent it should start specified activity after 20 mins of it's alarm off time.How it can be done ?
View 7 Replies View RelatedI added an intent filter to one of my activities, so that when a user clicks a URL like "www.mysite.com", and if my app is installed, my registered activity can be launched. It works well.
I see that this creates a new instance of my registered activity though, every time a link is clicked. Is there any way to prevent multiple instances from being created - just recycle an existing instance if one already exists?
I'm struggling with my app that launches multiple instances of the same Activity using the same intent. My main activity is of class type A and it does a startActivity() of two children that are of the same class type B. So we have B1 and B2 launched. If B1 and B2 are both paused (by pushing back button and making sure finish() is not invoked on them so they are truly paused), how can A uniquely bring either B1 or B2 to the foreground again? I do want to launch a new B activity. I want to uniquely bring B1 or B2 to the foreground.
so both B1 and B2 were created like this... Intent intent = new Intent(context, B.class); intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); startActivity(intent);
Now I want A to bring B1 (or B2) to the foreground/front so I use the below code, but how do I distinguish B1 or B2 when starting the activity? This only brings the last instance of B that was on top to the foreground.
Intent intent = new Intent(context, B.class); intent.addFlags(Intent.FLAG_ACTIVITY_REORDER_TO_FRONT); startActivity(intent);
I've tried keeping around references to B1 and B2 and doing something like this, but this also only goes to the last instance of activity class B that was on top...
Intent intent = new Intent(B1context, B.class); intent.addFlags(Intent.FLAG_ACTIVITY_REORDER_TO_FRONT); B1context.startActivity(intent);
I even tried this, but it still doesnt get me my unique B1 or B2... Intent intent = B1.getIntent(); // i.e. the original intent that started me startActivity(intent); // still only brings to front the last B that was on top.
Suppose I want to include data right in an intent, e.g. pass a number or string in the intent data field.What should the uri look like? Something like "data:3.14159"?Or just don't include the scheme at all, "3.14159"? In fact, is there a list of standard schemes anywhere?
View 4 Replies View RelatedI'd like to send an sms message. If the text is too long, I split it into multiple messages. I'm trying to put some extra info into the "sent" intent to know which part has been sent, and when all the parts are complete: The message is sent, and I catch the intent when each part is sent - but the intent always has the same data in it. For example, "partIndex" is always zero, even though for the second message, it should be one. Seems like the same intent just keeps getting thrown to my broadcast receiver. What's the right way to do this?
View 1 Replies View RelatedI would like to create some home screen app widgets that are entry points into an application. I can put a button in the app widget that uses setOnClickPendingIntent to start the activity. The problem occurs when I want to have two of these app widgets that are entry points to different parts of the activity. I need to be able to pass data into the activity that will distinguish these. Since both app widgets use a Pending Intent that starts the same activity, the two Pending Intents are shared and I can't reliably set extras for the corresponding intents.

It works fine if I specify a data tag with scheme="package" but then I get notified when any application is reinstalled or upgraded. I can't figure out how I'm supposed to specify the package name which is in the scheme specific part -- that is, when my BroadcastReceiver gets the intent in onRecieve(), if I do intent.getData().getSchemeSpecificPart(), that's the package name, but is there any way I can filter for only that in my intent-filter?
View 1 Replies View RelatedI 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)

The general use for multiple PDP (mPDP) is that when we use one PDP(A) to download a file, and we want to send a mms message via another PDP (B), the original PDP(A) will not be disconnected. This is the scenario on Windows Mobile. My question is ,if Android had supported mPDP, how does one application know which PDP should be used to transfer data?
Or Application (ex: Browser) doesn't care these issue, and it will try all PDP to transfer data ?
i need to parse this response in android using the android json parser but the thing i cant find the answer to anywhere is: how do i parse the data if for example "itineraries" can contain one or sometimes more objects of the type itinerary? if it contains one than it is returned like this but if it contains more it is returned with [] with this example "itinerary" cannot be placed into a JsonArray becouse obviously it is not an array. (not placed in [] right?)
how do i parse this? any examples?

I am working on developing an application that requires me to establish multiple client-server based connections. Connection can be of two types where the Android device can be a server or a client. I can have up to 6 - 8 connections. Once the connections are set-up they need to be running in the background and are not typically affected by UI actions.Since each connection can be blocking, I am wondering what is a good away to design this app. Should I have two services for handling the server and client connections? Each service could have a "connection manager" that can spawn new threads when necessary. Or does creating two services even help? I presume spawning new processed would not be good as they will be expensive. Is this correct? I would appreciate any suggestions. Also, if this use case is not typical please let me know if you need more information to make any recommendation.
View 2 Replies View RelatedI'm looking for suggestions for ways to share Android app data between phones running the same app. For example, lets say I have an app that stores a database of book reviews. If person A has a book review that person B doesn't have, what are the options for getting that information from person A's phone to person B's phone?
Currently, I'm aware of the following options:
- Upload data from person A's phone to a server, then download data from server to Person B's phone.
- Write code to have the phones sync up using bluetooth
- Write code to send SMS messages
I'm wondering if there are any more options besides these, and if there's actually a best-practice for accomplishing this?
Ideally, I want the users to simply click a button in the app to make the sharing take place, so I don't want to go down the bluetooth route because that requires the user to do a bit of setup (or assumes they already have set things up in the form of bluetooth settings).
Since the data can be of variable length and potentially large, I believe that would rule out text messaging.
As far as the server route goes, from what I understand this seems to be an ok way of doing things, but my problem is that I have no experience with having users potentially sign in to a server and then uploading data. I don't know of the cost concerns (if any), or of potential security concerns (allowing just anyone to upload data, I'm not sure if I would have to take steps to ensure someone couldn't bypass the app and upload malicious data).
Let's say I have a background service that performs several tasks. As it completes task A, it posts notification A with a certain intent and some extra data that indicates viewing result of A. As it completes task B, it posts notification B with a certain intent and some extra data that indicates viewing result of B. As it completes task C, it posts notification C with a certain intent and some extra data that indicates viewing result of C. At the end, the notification area has three notifications. Each one has the same intent, except for one of the extra data fields. I would expect that each one would load my activity with different extra data. They don't. When onNewIntent is called, each has the extra data field set to C. I have rooted out any possible aliasing and checked the data as it is placed into a notification. It seems to allow only one set of data per package. Is what I am attempting not possible? Has anyone accomplished what I am attempting? For example, have you had a service download several large files, and then had notifications that would open each of those. Code...

Now I have 2 activities that would simultaneously access one data/ settings. However, two kind of solution can be applied after I study from the Android Developer's Guild.One is ContentProvider, The discription in guild is as: "Content providers store and retrieve data and make it accessible to all applications. They're the only way to share data across applications; there's no common storage area that all Android packages can access."and another is SharedPreferences, "To use preferences that are shared across multiple application components (activities, receivers, services, providers), you can use the underlying Context.getSharedPreferences() method to retrieve a preferences object stored under a specific name."
View 5 Replies View RelatedI just encountered the following situation. I have an Android app with a scenario which I guess may happen in multiple apps. It's about tagging/labeling/categorizing, call it as you want.After CommonsWare's feedback here a bit of a clarification. I'm weird about doing the second query to the DB inside the CursorAdapter, basically this would result in one query per row and I fear this will heavily impact my performance (I've still to test it on a real device with a substantial amount of data to see how much this impacts).My question therefore is on whether there are some strategies on how to avoid this given my data model or whether I have to basically "live" with that :)
View 2 Replies View RelatedI am working on an android application, where there are 4 activities. Activity1 is main activity and there are different buttons on that activity which can open other activities. Other 3 activities can also open each other. There is a thread running in Activity1 which returns some counter. I need to show that counter on all activities. At an specific time, the thread doesn't know which activity is at top. What is the right way to control this scenario, such that thread output should update on all activities, no matter which one is at top?
View 1 Replies View RelatedSo my problem is that I've written a function that takes two Doubles, two Int, and a Calendar object on Android (Java). I believe the class provided to allow it to run in a separate thread, AsyncTask, accepts only one type of Object (but allows multiple) as an argument so I figured I might be able to put it in a List or a Linked List or something. Is there such a type that allows multiple data types like that (Double, Double, Int, Int, Calendar), or would I have to create my own object class? I'm a novice programmer so less complicated is probably better, but I'm interested in the best solution as well. What the function does is take a location (double latitude, double longitude), a couple options as integers, and a Calendar Object. It takes the location, options, and date then returns a Time object of the sunrise (or sunset, depending on the options) for that location. and I understand it would probably be best to create a special object class and just pass that, or override the background thread class, but I'm pretty new to object-oriented programming so the less overhead the better (for now). (Update) After a lot of work, it ended up being easier making a data-type class and just using that. The right way turned out to be easier in the end. Who'd a thought.
