Java

Due to popular demand I've finally released a major update for the Model Release Pal Android App - this was also due to the fact that Easy Release just released a version for Android (they have quite a popular one for the iPhone).

I also wanted to apologise to all the people that are currently using my app, for not having this update out earlier.

Have you seen other applications with Buttons (or other views, but mainly Buttons) that stay in one spot, even if you're scrolling through a list? These are commonly known as floating Buttons or Views.

This is actually used a lot on websites as well, and they may seem hard to produce at first glance, but it's actual quite easy.

I'll run you through an easy application that uses one floating button within a ListActivity, which is aligned to the bottom right of the screen - on top of the ListView.

This is a subject that's seldom talked about, but can be quite important. The NDK basically allows you to port any native C/C++ code/libraries into your Android project, using JNI (Java Native Interface).

I'm going to go through a quick and simple example of how you can display "Hello World" in your Android application using some native C.

A very annoying issue that I've noticed with the NBAndroid Netbeans plugin, is that it doesn't know how to properly attach an external JAR file to an Android Project.

If you right-click on libraries (under your project folder), and click on 'Add JAR/Folder', it will add a reference to that library/JAR file, which it will recognize in the code (detect all the classes, etc). The problem lies when you try to compile the project - at that point, it doesn't actually add the JAR to the project, which in turn gives you errors when running.

I'm happy to announce that my Allergy Pal application has finally been released!

This should be very useful for people suffering with allergies, and need a way to convey this to others - especially in other languages!

The Android SDK makes it very easy to send emails from an application, but unfortunately, that's only if you want to send them via the built-in mailing app. For most situations this works fine, but if you want to send something out and don't want any input/intervention from the user, it's not as easy.

In this article I'm going to show you how to send an email in the background without the user even knowing - the application will do everything behind the scenes.

The process for capturing, saving and displaying an image in Android can be quite annoying, especially if you want it to work across all devices.

With the release of the Sense UI (an HTC creation), it's made things 1 step more difficult. So, the reason I'm writing this article is because I've been stuck on this same issue for quite awhile, and there isn't enough information out there to let us know why it simply won't work.

Simply put, the Sense UI handles things differently when it comes to saving a new image after an intent was called (ie. new Intent(MediaStore.ACTION_IMAGE_CAPTURE)). In this article I'll show you how I overcame this problem and walk you through my code.

Have you been trying to find a quick and easy way to format dates from a String? It can be quite tricky with Java (if you're new to it). So, I'm going to go through a few very simple steps to accomplish just that.
