Anrdoid In-App Payment That Works

mobile monetization example

The first video of “The Zen of Monetization” is out!


Well, it’s a series of videos I’m creating, in order to cover different aspects of monetization. The goal is simple: help developers earn more from their work. In the first episode, we cover how to use In-App Payments. It’s a brief overview that gives the macro view. We have in the pipeline few more episodes that will cover it in more details with (of course) code samples.
If you wish to get it as an article (and not a video) check this “Android in-app payments” post.

Chrome 47 Updates And Web News

  • google-chrome-logoInput Device Capabilities: Chrome 47 has a new feature that makes it easier to understand the how users interact with your site: InputDeviceCapabilities! DOM input events are an abstraction above low-level input events, loosely tied to physical device input (e.g., click events can be fired by a mouse, touchscreen, or keyboard). However, there is a problem: there is no simple method to obtain the details of the physical device responsible for an event. In addition, certain types of input can generate further “fake” DOM input events for compatibility reasons. One such fake DOM event happens when a user taps a touch screen (such as on a mobile phone); it not only fires touch events but, for compatibility reasons, mouse events as well. The new InputDeviceCapabilities API provides details about the underlying sources of input events this come to helps with problems when supporting both mouse and touch input. Read More:
  • Adding a Splash screen for installed web apps – Over the past year we saw an effort in the Chrome team to let developers build sites and apps that feel like they are installed on the user’s system. The home screen launch process on Android is a great first step. In Chrome 46 on Android, we got the background_color that removes any delay and paints the screen with a solid color until the browser is ready to paint something from the web page. This was a good addition, yet it still didn’t look fully like an app. Now in Chrome 47 on Android, Beta these days as of October 2015, we are introducing the concept of a “splash screen”. Have a look:

HTML5 On Mobile Devices (iOS, Android & Windows)

More and more we see mobile devices with stronger browsers that implement a lot of HTML5 APIs. This is other factors are the root cause that mobile development has taken off. Many developers are choosing to go the mobile web route instead of writing the same application repeatedly for each different mobile platform. However, one of the things that you give up by “going web” is the application frameworks that make life easier for developers of native mobile applications. As a result, several web application frameworks are emerging. In this post I will look at some of the best frameworks: jQueryMobile and Sencha Touch. There are some other very good MVC frameworks that are worth look into: SproutCore, Cappuccino and backbone.js but that will be in another story (=post).

Let’s start with one of the most popular JavaScript library – jQueryMobile It’s now in version 1.0 and it’s a powerful HTML5-based user interface system for all popular mobile device platforms. They have a set of UI components that give the developers a lot of power. Its lightweight code is built with progressive enhancement, and has a flexible, easily themeable design. If you are developing apps for business (think components like grids) you might want to take a closer look at Sencha ExtJS and other products. They have a good integration with GWT (if you use it) and overall, they give the developer a lot of power: clean component model, powerful UI widgets etc’. There are some new capabilities that give more native look and feel to your web apps. The first is the Fixed position – Psss… its great for your menu at the top of the screen. I hope will see its adoption on other mobile browsers (and not just the safari 5+). Another cool aspect is the new ‘Path‘ button dynamics all in pure CSS and scroller live demo.

The wave of HTML5

The wave of HTML5 apps is here


One of the ‘easy’ parts it the deployment. Once users added your web app as shortcut to their home screen it will be there and updated each time they starting it. You can also, use the Android, iOS stores with a webUI wrapper and tools like AppsGeyser or AppCelerator that will do the work of wrapping for you. I hope that in the future the webUI that we get in iOS/Android will be as good as the webkit we have in the browser on the same platform. Currently, it’s got some limitations. Lastly, in case you wish to check what HTML5 features will work on each device you are targeting: This is a good source: and for more stats and development tips checkout my last post on html5 on mobile.
