As mentioned Eclipse if the most popular, the other 2 main players are Motodev Studio and IntelliJ IDEA. I've heard people are also using NetBeans.
Eclipse can run on a number of platforms. I use a Mac but I'm guessing most use Windows.
Eclipse is free and most of the support forums relate to Eclipse.

I am programming for Windows Mobile 6.
I am writing an application. Here is the design:
1) A textbox for user to scan a barcode.
2) After scanning, automatically call web service to search the database.
3) If found data, display in a table below.
To solve 2, I use text1_TextChanged(). However, as the barcode is long (some 11 characters), the TextChanged() function is called more than 11 times. That means the database is searched for more than 11 times. The performance is too slow.
I have searched the web and find out this:
.NET — Textbox control - wait till user is done typing[^]
I use the timer approach, but find out the tick function is called 11 times. Any help?
(Please note that the barcode is scanned in, not typed in.)
[Edited at 2012-08-16] The project is a bit complicated now. The textbox could hold any number of characters from 4 to 24. So I cannot just count to the end. If I start querying the database once I have at least 4 characters, I could end up with searching 20 times...

I may be wrong about this (I have no experience with Windows Mobile), but isn't there any way to check for how many characters have been entered in the text field?
I mean, you said the barcode is some 11 characters, but does it have any lower bound? (for instance, it can't be shorter than 8 characters). Then, when it reaches the lower bound, you can start querying the database from there.
Also alternatively, instead of querying the database automatically when the code is scanned, you could add another button for a manual scan - when the user finishes scanning the barcode and the textfield is completed, show him another button to do the search and display the results in the table. In this case, there is another click for the user, but I think the performance benefits far outweigh the usability drawbacks

Hi Andrei,
I cannot start from the lower end. The number of characters now could range from 4 to 24. So if I start off with lower bound - 4 characters, I could end up checking the database 20 times.
Of course, I know the solution to add the button to manually trigger the checking of database, but I still want to have the automatically checking.

You have not exactly given much specific detail as to your requirements bu the Java Tutorials[^] would be a good place to start.

What sort of help do you expect from a question like this? We have no idea what you mean by "Tone Generator"; please be clearer with what you have done so far and where you are having problems. If you are just looking for sample code then go to the Android articles[^] here on CodeProject.

hi friends..
Tone Generator Pro automagically creates perfect Sine Waves, Square Waves, Triangle Waves, Sawtooth Waves, Reverse Sawtooth Waves, White Noise and Pink Noise!
It can utilize these amazing tools for many day to day activities, such as:
Testing Speakers
Balance your Home Theater speaker levels
Generate all the most common waveforms from 20Hz to 20kHz
So,i am developing this using tone generator class which is present in android java.But i couldnot run it so please
can you suggest me what are the permissions are needed to be included in app development.
thanking you,
naseer

Hey all,
I own an HTC Desire HD, and as the little HTC elephants thought of not updating it to Android 4.0, I'm really thinking about getting a custom ICS ROM for it. After looking a little on the interwebz, I've found Ice Cold Sandwich[^], which seems to be pretty nice, and relatively stable (if one were to believe the reviews).
Now, does anyone here own an HTC DHD? And if you do, do you have a custom ROM as well? What has your experience been, and is it worth installing it, taking into consideration that some things ([sarcasm] nothing important, like camera and microphone [/sarcasm]) may not work?

Have you read this[^]
I find fragments a bit of a pain as well, but if you're building a tabbed application, you don't have an option. On the good side they provide reusable components

an activity typically fi lls the entire screen, displaying the various views
that make up the user interface of an application. The activity is essentially a container for views.
However, when an activity is displayed in a large-screen device, such as on a tablet, it is somewhat
out of place. Because the screen is much bigger, all the views in an activity must be arranged to
make full use of the increased space, resulting in complex changes to the view hierarchy. A better
approach is to have “mini-activities,” each containing its own set of views. During runtime, an
activity can contain one or more of these mini-activities, depending on the screen orientation in
which the device is held. In Android 3.0 and later, these mini-activities are known as fragments .
Think of a fragment as another form of activity. You create fragments to contain views, just like
activities. Fragments are always embedded in an activity. For example, Figure 2-15 shows two
fragments. Fragment 1 might contain a ListView showing a list of book titles. Fragment 2 might
contain some TextView s and ImageViews showing some text and images.
For More detials i recommend you to explore this book : Professional Android Application Development book reviews[^] you will find all the details about fragments in the page 69 with code examples.
