Android is "available" in a lot of respects, unlike Apple, the main example is that the Android operating system is built on the "Android Open Source Project," or AOSP, code. Users may opt to install apps from other outlets such as a flash memory card or a third-party app store such as the Amazon AppStore, Getjar, etc. Android coding is therefore a lengthy and time-consuming process, however, Zazz is known to deliver apps in record times.

Moreover, they test the various external factors that may hamper the application’s work (network conditions, call interruptions, SMS, and more). The mobile testing team at Zazz will ensure the device has a user-friendly Interface, encompassing the app's core features and engaging UX, delivering meaningful user experience. Our mobile development department also carries out usability testing as part of the UX research to ensure the app is convenient and easy to use for your target audience.

Our Android App Development Approaches

Native applications are primarily developed for one single platform. There are programming languages related, that are unique to one platform. These languages tend to be Java or Kotlin for an Android application, and an iOS app, Swift or Objective-C. Since these apps are built-in platform-specific languages they can only be used on that platform. For instance, if you've created an iOS app, it'll only function for iPhone users. This won't appeal to an Android user's needs. So, if you want to have a business app on these two different platforms you'll need to have two versions of an app ready.

A hybrid framework is based on a Web view that runs in a native device on a web browser. It uses a native app wrapping to create connectivity between the web view and the interface for native behavior. The hybrid app is called native because, much like a native app, you can download it from the app store market. Hybrid apps link the native platform to the web view and are developed employing tools that help them operate without burdening phone storage. These are third party resources such as Apache Cordova. Zazz ensures that our Hybrid apps are the most cost-effective and feature-packed.

Why is Zazz so Unique & Successful?

First, we carry out the first contact with the client in which the ideas they have and the objectives they intend to bring to reality are put in common. Besides, a study of the user profile is carried out, at the same time, we advise and offer our perspective of the success of the proposed future project. Once the central ideas that will give life to the development of the application are marked so that it is effective and viable. We move on to graphically design the project using mockups. Thus, the preview is created through which the client can see what they want it to look like visually.

Once the mockups are accepted, work begins on the implementation and development of the app itself. It is carried out faithfully following those objectives that were initially established and all the points that the client requested are brought to life. In addition to monitoring the process and functionality to ensure that everything is going as planned. Our projects end when the client's needs and objectives are captured.
