iPad or iPhone app won't open - solution/help

I just ran into the craziest problem where I couldn't get any third-party apps on my iPad to open. I'd tap them, there'd be a quick blink, then nothing, I was back to the home screen with all my app icons.

How to make a phone call from your Android app

I came across this Android phone dialer tip yesterday. If you want to make a phone call from an Android application, all you have to do is create a new Intent, either an Intent.ACTION_DIAL (to start the call) or Intent.ACTION_CALL (to place the call).

Here are the three lines of source code you need to get started:

Android emulator not loading my app

I haven't used Android in a little while now, in particular with my new laptop, and the first time I tried running an Android app from inside Eclipse, the Android emulator wouldn't finish starting properly and run my app.

I remember I used to look under the "all apps" icon, and could sometimes find my app was actually loaded, but in this case, it wasn't loaded at all.

iPhone and iPad JavaScript dialogs (alert, confirm, prompt) and windows

iPhone JavaScript dialogs FAQ: Can I use JavaScript windows and dialogs in my iPhone HTML app (the JavaScript alert dialog, confirm dialog, and prompt dialog)?

Yes you can. According to Apple's iOS Safari web documentation, you can use "iPhone JavaScript windows and dialogs" that are supported by iOS. Here's how.

Mac startup/login programs (startup items)

Mac startup/login programs FAQ: How do I set up a Mac program to automatically startup when I log in?

If you have a normal Mac application that you want to setup as a Mac startup program (also called a Mac "startup item"), the process is fairly simple, and I'll demonstrate the approach in this article. For other Mac applications, like a command line program, the approach is different, and I'll cover that in a separate article.

iPhone HTML apps - Conditional iPhone style sheets

iPhone HTML web app style sheets FAQ: I'm trying to optimize my HTML/web app for the iPhone, how do I specify a style sheet to be used for just the iPhone?

There are several different approaches you can take, but with CSS3 the most direct approach you can take is to add an expression to your iPhone CSS link tag, as shown here:

iPhone HTML apps - Using an app startup image (app splash screen)

iPhone HTML apps startup image FAQ: How do I set the startup image (splash screen) for my iPad or iPhone HTML app?

This quick blurb from the Apple developer documentation leads us to the answer:

On iOS, similar to native applications, you can specify a startup image that is displayed while your web application launches. This is especially useful when your web application is offline.

By default, a screenshot of the web application the last time it was launched is used. To set another startup image, add a "link" element to the webpage.

iPhone HTML app full screen mode - How to remove the URL and button bars

iPhone HTML web app FAQ: In an HTML web app optimized for the iPhone, how do I remove the URL bar on top of the iPhone Mobile Safari web browser so I can show my HTML app in full screen mode?

When you're creating an HTML/web app to look like a native iPhone app, one of the things you'll want to do is remove the URL bar in the Mobile Safari web browser. This is the URL bar on the top of the iPhone browser, and by getting rid of it, you can display your web app on the iPhone in full-screen mode.

A Drupal jQuery Mobile theme - screenshots

Summary: A Drupal jQuery mobile tutorial/demo.

As I wrote yesterday, I just started working on a mobile Drupal app (web app) that uses jQuery Mobile to make the app look and function like a true mobile app. Yesterday's article was about creating a Drupal mobile theme using jQuery Mobile.

I didn't get a chance to work on this any more today, but I thought I'd share a couple of screenshots from this Drupal mobile web app to show you what I'm doing.

Drupal iPhone apps and mobile themes

Drupal iPhone mobile themes, special introduction: In this article I take a quick look at the existing Drupal iPhone themes. The reason I say this is a "quick look" is because none of the themes seemed to work very well out of the box. This is a bummer for me, not only because I have a lot of work to do, but because I normally like to share solutions to problems.
