In the scenario that I made up a user chooses an application and and I offer him/her the available pieces of data to operate on. I know that the possible data type for an application is specified in its manifest file and I suppose that this information is available, but I have some difficulty finding out what the data content type for application is?

So 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.

Intent intent = new Intent(); intent.setAction(Intent.ACTION_GET_CONTENT); intent.setType("*/*");
Intent newIntent = Intent.createChooser(intent, null); startActivityForResult( newIntent , SHOW_VERIFY_ACTIVITY );
And the wildcards work. But I would like to be more explicit. Like the following:
intent.setType("vnd.android.cursor.item/contacts");
...but is not valid.

I pick a contact in my app to get its phone number and if there is more then one number I use an AlertDialog to let the user select the currect one. In this pick list, I want to show the label of the type, so it's easier for the user to select. Since they labels are somewhere in the Android system, it must be possible to get the localized label. Unfortunately, the Phone.LABEL is null when reading the phone number.
There is a description about a product or event that people would like to share among them. This can be a simple text or rich text too.
They are looking into which format is the best for this purpose. They would like to see compatible with as many phones as possible. We are talking about phones that have Bluetooth.
Also the text is longer than the length of an SMS, so the SMS format is not suitable
What would you recommend?
And what do you think what would be the best way to share that between phones?
Would this Android code be a correct way to test for http network availability during a phone call, or does it exclude networks that should be included or vice versa:

I'm just wondering what types of accessories Droid users have bought. I have the Multimedia docking and the car dock both from Motorola. I bought them on the VZW website and got both for around $22 bucks each. I've been happy with both even though I haven't been driving much. Has anyone seen a car dock that doesn't block the camera? Mine does. I wanted to launch Qik or Ustream Broadcaster while I drive around. Just thought it would make for some cool video.

View 21 Replies View RelatedI want to have a different alert tone or ringtone for different types of notifications: a different one for texts, for emails, and for voicemails. I have been able to do this with just about every other type of phone I've had in the past; I can't understand why these more expensive, more technologically advanced phones dump them all into one category ("Set as notification tone"). Am I missing something here? Is there an app I need or a setting on the phone I'm not seeing?
Just to be clear, I care less about whether I can use customized ringtones for these alerts than just being able to distinguish between when I'm getting a text or an email. And if it helps to know, I have a Samsung Moment and my husband has a HTC Hero, and we are both having this problem.
I have an issue with using contacts on my droid.

I can't find the option when adding a new contact or when within the display options as mentioned before.

Anyone seen a general list or data manager app for Android? Not looking for a to-do list or task list - but a general list manager where I can define my own tables and fields, edit data, filter, sort, etc. Syncing to a PC app would be great, but I don't really expect that.If anyone has used Listpro fom Ilium Software, on Palm or Win Mobile - that's what I am looking to replace.I may end up using Excel spreadsheets with Documents to Go from Dataviz - and some general sync tool for PC to phone data sharing - but Listpro was so good, I'll miss it!

View 12 Replies View RelatedI juststarted programming in android a few weeks ago, so I am not entirely sure how to deal with listing values. I have some questions regarding displaying data sets from db in a list. Currently I have a cursor returned by my db points to a list of rows and I want display 2 columns values in a single row of the list.
The row xml looks like this:
CODE:...............
so I was thinking using simplecursoradapter which supposedly makes my life easier by displaying the data in a list. However that is only true if I want to display the raw data. For the purpose of my program I need to do some computations on the raw data sets, then display them. I am not sure how to do that using SimpleCursorAdapter.
Here's how I display the raw data:
CODE:.........
Is there a way to do computation on the data in those rows before I bind it with the SimpleCursorAdapter? I was trying to use an alternative way of doing this by using arraylist and arrayadapter, but that way I dont know to how achieve displaying 2 items in a single row.
This is my code for using arrayadapter which only display 1 text in a row instead of 2 textviews in a row:
CODE:.......
It's very obvious that it only displays one textview in a row because I set the second arrayadapter overwrites the first one! I was trying to use R.id.text1 and R.id.text2 for them, but it gave me some errors saying 04-23 01:40:58.658: ERROR/AndroidRuntime(3309): android.content.res.Resources$NotFoundException: Resource ID #0x7f070008 type #0x12 is not valid.

I need to be able to scroll through a list with (up to) 20K rows, backed by a cursor on a read-only db. Testing 20K rows on a G1, the query takes approx .02s regardless of table size, while binding the adapter to the list takes 4.5s. Note that this is before the view calls used in rendering. What makes the binding delay more troublesome is that it blocks the UI thread, and is incurred on every rotate. Combine these, and doing a rotate just after starting the bind results in a delay up to 9s.
I tried lazy loading with a base adapter, but that hits the same delay in the underlying cursor.getCount(), and the overall user experience isn't ideal. I also considered using an ArrayAdapter, adding synthesized objects from the cursor rows, but then I'd incur the overhead of creating up to 20K objects (not to mention the additional memory requirements).
Is is possible to specify data in xml resource file and initialize ArrayList from it? I am looking for a way to use the ArrayList with a SimpleAdapter to bind to a ListView. I am wondering if there is a way to specify my data in xml resource file and init ArrayList from it.
