I've been looking the source code available from the Restlet official tutorial.
I am trying to hit the Restlet server using the Android app from he tutorial adn I only get the JSON response, not the Java Object. I tried using all libraries and extensions, nothing works. When I hit the tutorial url though (http://restlet-example-serialization.appspot.com/contacts/123) I get the desired response. Any ideas? BTW, I am just using the server (GAE) in the example, not the GWT frontend.
I know about camel case rules, but I'm confused with this m rule. What does it stand for? I'm a php developer, "we" use first letters of variables as indication of type, like 'b' for boolean, 'i' for integer and so on.
Is 'm' a java thing? Does it stand for mobile? mixed?

My emulator now works (and i can run it and get the default android screen) however when i try to run the hello world sample code i get this error message:
An internal error occurred during: "Launching HelloAndroid". java.lang.NullPointerException
I am trying to write a sample program to record the video (say camcorder application). When i run my program using the emulator (I have android-sdk- windows-1.5_r3) I see java.io.IOException: prepare failed. error in logcat output.
Further I can see that I have came across this error when i call MediaRecorder.prepare() from CamcorderActivity.surfaceCreated() But I am surprised to see that activity got launched and I am seeing the camera preview! Again the preview is seen only in half of the screen! Its weird!!!
Further when i do recorder.start() to record the video I get java.lang.IllegalStateException. Yes this is obvious since the prepare () has failed. But the question is why prepare() has failed ?
Here is my code ... package com.example;

I've seen a few places where this was asked but I haven't seen where it's been resolved. I've just installed the tools needed to develop Android applications. This includes, of course, Eclipse. When I try to open the res/main.xml file, I get the error 'could not initialize class java.awt.font'.I'm running the newest version of Eclipse and all the software required for Android development. I'm running on Ubuntu 10.04 32bit. Sun JDK and JRE are installed.

What's the reason for this and how I fix it?
Eclipse Helios 32 bit

P.S. Im new to Android development.
EDIT: I tried most of you solutions, but nothing worked. So I started using my frineds install of Eclipse Ganymeade.
Im trying to display this listview, but I keep getting a: 07-17 21:14:22.233: ERROR/AndroidRuntime(349): java.lang.NullPointerException
I think I know what the problem is but I dont know how to fix it.
I have a String array which I will be using to be displayed in my list
CODE:.....
Dont worry the parser works great. the only problem I see with it is that the parser doesnt know how many strings the website will have so I am setting the String array in the parser to be very big: String substr[] = new String[250];
But I know that mostly there are only like 11 to 13 values that I will be storing in that array, the problem I think is when i do this:
CODE:..............
Since the String array is set to have up to 250 values in it and I only actually store say 12 then there are a null entries so when I run the code it shows me my list view, but when I get to the bottom of the view it force closes and the log tells me that there was nullpointer. I can tell how many entries I collected while I am parsing, but how do I tell my listview to only show say 12 items in the list so there wont be any null entries. or is there any other solution for my problem.
I tried doing what you said, but now I am getting a:

When you get an error like the one below (Android 1.5), is it because there are too many nested ViewGroups, or because the total number of Views is too great? Are there any tricks to get around it while still keeping the same look to your app?

Well let me explain what my program is doing. I have a server that starts when my application is started, and the client pings the server and asks to get a list of installed applications. The Server then asks the getPackageManager() and gets all the installed applications. But the getPackageManager returns the nullpointerexception. The Server is written in a java environment and is started from my android application. Could someone please tell me what am missing and why i am getting this error? hanks alot!!!Please find the code...

I am getting following error while updating my twitter status from java code in android using Twitter4J .

I have a service running that updates a notification in the notification bar when it recieves a message saying it has to be changed.
However I get the following error sometimes when the notification is to be updated
java.lang.IllegalArgumentException: contentIntent required
Here is my code:

So something is happening my contentIntent somewhere along the line, would that be correct?
It is declared at the top of my Service class as a member variable and is not used anywhere else in the code apart from shown above, so where could it be getting reset to null?

View 1 Replies View RelatedI have a custom view that I had to write for a large scrollable image, as the images are larger than the size of the screen. Before, I had tried to do it by putting the image into a ScrollView but that of course didn't work. The view itself is within a RelativeLayout within the activity and at the bottom of the screen I have two buttons that are used for navigation and at the top a TextView with a caption for the activity (the main header is already being used here for instruction). In my below code, I've checked the Hierachy Viewer to confirm all the elements are loaded and in the Activity I can see the TextView, however it overlays the ZN5ScrollView area and below the image I just have a blank area of the size defined rather than my buttons. For the bottom navigation, the Hierachy Viewer is saying the absolute_y of the bottom navigation is 480. I'm wondering if anyone can help with my layout code here to get this working correctly? Bottom navigation is 50px high, ZN5ScrollView is 365px above the navigation, and the TextView takes up the rest of the area at the top
