How Global Positioning System tracking works


TrackMe serves not only as a simple tool to track objects online, but it can also be a lifesaver. The devices that are integrated with our systems can ensure tracking of almost any object be it vehicles, but also the track Life. Be it tracking of Children or even Pets, our services are very broadly designed to capture and serve all aspects that needs to be considered.

All the tracking devices installed on vehicles will communicate with the TrackMe server. The server has the capability and interfaces to communicate with a variety of devices through SMS and GPRS in synchronization.

The server will maintain a registry of tracking devices set for monitoring.

Android app architectures Standard Android MVP and MVVM

0 comments

Archi


This repository showcases and compares different architectural patterns that can be used to build Android apps. The exact same sample app is built three times using the following approaches:


Standard Android: traditional approach with layouts, Activities/Fragments and Model.

MVP: Model View Presenter.

MVVM: Model View ViewModel with data binding.


The App


The sample app displays a list of GitHub public repositories for a given username. Tapping on one of them will open a repository details screen, where more information about the repo can be found. This screen also shows information about the owner of the repository.


MVP: Model View Presenter


 


Libraries used


  • AppCompat, CardView and RecyclerView

  • Data Binding (only MVVM)

  • RxJava & RxAndroid

  • Retrofit 2

  • Picasso

  • Mockito

  • Robolectric

Standard Android


The /app directoy contains the implementation that follows the traditional standard Android approach. This is a couple of layout files, two Activities and the model. The model is exactly the same for the three implementations and it contains: Repository, User and a retrofit service (GithubService).


With this approach, Activities are in charge of calling the GithubService, processing the data and updating the views. They act kind of like a controller in MVC but with some extra responsibilities that should be part of the view. The problem with this standard architecture is that Activities and Fragments can become quite large and very difficult to tests. Hence why I didn’t write any unit test for this case.


MVP – Model View Presenter


In /app-mvp you will find the sample app implemented following this pattern. When using mvp, Activities and Fragments become part of the view layer and they delegate most of the work to presenters. Each Activity has a matching presenter that handles accessing the model via theGithubService. They also notify the Activities when the data is ready to display. Unit testing presenters becomes very easy by mocking the view layer (Activities).


MVVM – Model View ViewModel


This pattern has recently started to gain popularity due to the release of the data binding library. You will find the implementation in /app-mvvm. In this case, ViewModels retrieve data from the model when requested from the view via data binding. With this pattern, Activities and Fragments become very lightweight. Moreover, writting unit tests becomes easier because the ViewModels are decoupled form the view.

How to create anything in Android

0 comments

Course Summary



Here is one important question Android developers ask while making apps: “How can I do ________ in Android?”


The following are versions of this question that we came across recently:


  • How can I add radio buttons to my app?

  • How can I play a sound?

  • How can I navigate between multiple screens?

This course is a collection of such questions and their answers.


By the end of this course you will have mastered the ability to implement new Android features by reading a blog or article — this is a critical skill possessed by professional Android developers. As a result, you will also be able to use several User Interface components — like Toggle Buttons, Menus, Grid View and many more — that are central to making functional and delightful Android apps.

Google Play APK size limit increased to 100MB from 50MB

0 comments

To support the growing number of developers who are building richer apps and games on Google Play, we are increasing theAPK file size limit to 100MB from 50MB. This means developers can publish APKs up to 100MB in size, and users will see a warning only when the app exceeds the 100MB quota and makes use of Expansion Files. The default update setting for users will continue to be to auto-updating apps over Wi-Fi only, enabling users to access higher quality apps and games while conserving their data usage.


Even though you can make your app bigger, it doesn’t always mean you should. Remember to keep in mind the following factors:


  • Mobile data connectivity: Users around the world have varying mobile data connectivity speeds. Particularly in developing countries, many people are coming online with connections slower than those of users in countries like the U.S. and Japan. Users on a slow connection are less likely to install an app or game that is going to take a long time to download.

  • Mobile data caps: Many mobile networks around the world give users a limited number of MB that they can download each month without incurring additional charges. Users are often wary of downloading large files for fear of exceeding their limits.

  • App performance: Mobile devices have limited RAM and storage space. The larger your app or game, the slower it may run, particularly on older devices.

  • Install time: People want to start using your app or game as quickly as possible after tapping the install button. Longer wait times increase the risk they’ll give up.
