I have an application that queries a server (not under my control). The server returns a serialized object. I have the model for the class - however the problem is that the class is in "default package"... something not recognizable by Android ClassLoader. How can I resolve this issue?

I've got a strange problem here doing object de/serialization. In Java (JDK 1.6) I serialize some objects. In Android (SDK 1.1) I deserialize them. This work quite nice in general. In order to work with a server object (that uses Castor un/ marshalling) I do it like I always do. Same routines. Well, this time the file is only 172kb (my routines works pretty well with 2,4mb files) but the interlacing is quite deep. So it all starts with a class containing 2 ArrayLists. I tried de/serializing just ArrayList<String> and this works very well. But the XML file (which is unmarshalled with Castor and serialized in JDK) has 7000 lines. So I get this StackOverflowError....................

I'm building simple app, simply to learn the android ropes, that will display a list of the most recent photos uploaded to flickr. The app is constructed but it's crapping out when it tries to deserialize the json that I get back from flickr. Here is my error:

From, the error I'm assuming it has something GSON doesn't like about the json that is being returned but I don't know enough about how java converts objects and other types of variables during the whole operation.
I'm not sure if you will need this but here is some of the code from the project:

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. My question is how we can get the pointer of the second Activity after the it is shown by clicking the button on the first activity.?

This is the android URI returned by android.provider.MediaStore.Images.Media.INTERNAL_CONTENT_URI content://media/external/images/media/3
When I try to construct a java URI object from this object, I get an IllegalArgumentException with the exception description Expected file scheme in URI: content://media/external/images/media/3 whereas the android URI shows the scheme as content
Never found a solution for the original question. But if you want the byte stream of an image in the pictures gallery, this piece of code will do that.

View 2 Replies View RelatedI am working on a program that will connect to a time server (time- a.nist.gov), retrieve the timestamp, and place it in a text field.
However, when I create the socket, I get an UnknownHost Exception for time-a.nist.gov
1. put the <uses-permission android:name="android.permission.INTERNET" /> tag right before the </ manifest> tag. I did this, and the change is still there.
2. use the static InetAddress.getByName() function to convert to an IP address (this still throws the same exception)
When I pass the IP address (129.6.15.28) to the socket constructor, the program works fine. It only breaks when I use the actual domain name.
I have written this program in Java and it works perfectly fine.
I will try to keep it simple:

View 1 Replies View RelatedI have an application which has 11 different activities. One of these activities is an extension of MapActivity (it is a map for data visualization). To get to this activity the user must first travel through the launch activity, then 3 other activities.

View 1 Replies View RelatedI'm using "AppBrain App Market". I have installed a bunch of apps, but some get stuck and just stay in "Downloading" state. They just never finish downloading. I see the progress bar "barbershop pole" style but there is no sign of progress. Some are new installations, some are updates.
This is despite the fact that some apps HAVE successfully downloaded and installed. What could the problem be? How do I resolve this?
Cancelling the download and restarting the download resolved the problem once. (Downloads / click on neverending download item, Cancel Download)
But if the button series is (Downloads / click on neverending download item, *Installing*). Then the Installing button is greyed out then I'm stuck.

I'm trying to put a spinner in a sub-tab in my android app. Touching the spinner causes a crash.

Has anyone resolved this?
