Android :: Serializable Object In Intent Returning As String
Jun 16, 2010
In my application, I am trying to pass a serializable object through an intent to another activity. The intent is not entirely created by me, it is created and passed through a search suggestion.
In the content provider for the search suggestion, the object is created and placed in the SUGGEST_COLUMN_INTENT_EXTRA_DATA column of the MatrixCursor. However, when in the receiving activity I call getIntent().getSerializableExtra(SearchManager.EXTRA_DATA_KEY), the returned object is of type String and I cannot cast it into the original object class.
I tried making a parcelable wrapper for my object that calls out.writeSerializable(...) and use that instead but the same thing happened.
The string that is returned is like a generic Object toString(), i.e. com.foo.yak.MyAwesomeClass@4350058, so I'm assuming that toString() is being called somewhere where I have no control.
Some of my code
CODE:.........
This is in the activity that receives the search suggestion:

I'm trying to use ksoap to call a simple webservice. I followed this video to try to get started. When I call "getResponse()" on the envelope I just get the string "Error". There's no exceptions thrown or any other detail. I've successfully connected to a simple webservice I just setup on my local machine. Could this potentially be related to being behind a proxy server here at work? My code is below:

I have an application that needs to have a user visit a web page to authorize it. After spending time in the Browser the user should return the my application.
Currently, I'm launching the Browser with:
CODE:................
After using the browser, I can go back home and launch my application, which stacks a new Activity on top of the previous stack of Activities that were being used in the application. For example. If the user launches the app, they have Activity A in the stack. From there we navigate to Activity B which then launches the Browser. Then, the next time we enter the app, we launch Activity A, which is pushed onto the stack that already contains an A and B.
My question is then, how can I just go back to the previous stack? Basically, do I have to create a new Activity? Is there a better way to launch the Browser, and then come back to my application?
Also, I've been using the Intent.FLAG_ACTIVITY_NEW_TASK when I start the Browser activity so that my app stays running.

So I ran into a problem today while working on my Android program. I have a class that turns that an XML string into a Java object (third party) and it works fine in as a regular java project but on Android I get this weird error:
CODE:.......
I hide my application name and my package for obvious reasons but I was wondering if anyone has ever encountered problems like this. Class is in the correct package, which is a library I have added. Other classes that I reference before are there and those can be made. Are there any other reasons a ClassNotFound Exception is thrown?

Perhaps I'm misunderstanding how Intents and intent-filters work, but it seems to me that this should be a strait-forward case. However it's not working. Here is the Intent I'm sending:
Intent i = new Intent(Intent.ACTION_VIEW);
i.setType("vnd.android.cursor.item/vnd.connectsy.event");
startActivity(i);
And here is the intent-filter:
<activity android:name=".events.EventView">
<intent-filter>
<action android:name="android.intent.action.VIEW" />
<data android:mimeType="vnd.android.cursor.item/vnd.connectsy.event" />
</intent-filter>
</activity>
And finally, the error I'm receiving:
android.content.ActivityNotFoundException: No Activity found to handle Intent { act=android.intent.action.VIEW typ=vnd.android.cursor.item/vnd.connectsy.event }

I 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?

The first activity in my app needs to load a small amount of data from a text file. Two strings and an integer. Once I load the data, I want to use one of the strings to create an intent, that will launch the next activity.

I have a program that sends a broadcast Intent that needs an "extra" value.The value is declared as being of type Object[], though I know that the elements are always of type Integer or String.That's part of an API not under my control. What's the most concise and/or efficient way to do the equivalent of the putExtra call below?

I have a Service defined in the manifest with an intent filter that refuses to match when specified as a String resource but works when the literal action is entered in the manifest. Is there any reason I should not be able to use a String resource with an action in an intent filter?

I have a bunch of objects that implement Serializable that I want to store in a SQL database.
I have two questions:
Is there a way to serialize the object directly into the database. Is that the best way to do it or should I Write the object out to a formatting String and put it in the database that way and then parse it back out
Write each member to the database with a field that is unique to each object.

Why does Android provide 2 interfaces for serializing objects? Do Serializable objects interopt with Android Binder and AIDL files?

was wondering about the behavior of Bundles and serializable objects. If I put a serializable object into a bundle, what is serialized then, the reference to the object or the object itself? I always assumed that the object itself would be serialized to a byte stream when calling putExtra() and re-created from that representation when calling getSerializableExtra(), but I recently stumbled upon a piece of code that put an entire view into a Bundle in thread A, retrieved it from that bundle in thread B, performed a modification on it and this modification actually became visible. This can only happen if the reference to that view was stored, not the view itself, right? Otherwise, the modification had been applied to a copy of that view and would be meaningless.

I want to do some automated testcase with Instrumentation . Suggest that my AUT has 2 Activity. After clicking the button in ther first Activity, the second one will be shown with new content base on what we enter in the first Activity.) Instrumentation provides us the function called startActivitySync() and return the Activity object for processing.

I have the localized strings file that is used in the Iphone app that I work on to port to Android. Are there any tools that go through the file taken from the xcode project and build the xml needed to use the strings in android? This tool should be easy to build but I appreciate any pointers to already working tools.

In Android, capturing date from datepicker and storing as string in sqlite. Sorting by date doesn't work because they're strings (unless I'm doing it wrong.I've googled this issue for ~5 days, and it looks like there should be a way to capture the date from the date picker, convert it to a Long, store it in sqlite as a Long, select and sort on the Long date value, then convert the Long back to a "mm/dd/yyyy" string for display. I've tried various combinations of parse statements, Date, FormatDate, etc. with no luck at all.On activity start, get today's date and display it in button which calls the datepicker.Capture new date from datepicker (if one is entered), save it as a long to sqlite.On opening an activity showing a listview of records, select from sqlite with orderby on date (Long), convert Long to "mm/dd/yyyy" string for display in ListView.

I have preferences where you can enable/disable what items will show up on the menu. There are 17 items. I made a string array in values/arrays.xml with titles for each of these 17 items.
I have preferences.xml which has the layout for my preferences file, and I would like to reference a single item from the string array to use as the title.
In the Android developer reference, I see how I can reference a single string with XML, but now how I can reference a string from an array resource in XML.
