Apr 21, 20180 likes79 views

This document discusses the MVP+C architecture pattern for mobile applications. C stands for Composer, a class that composes streams of processes and has an activity or fragment lifecycle. The composer handles errors from data sources like servers using Retrofit or local storage with DBFlow. Dependency injection with Dagger and reactive programming with RxJava are also discussed. Sample projects and links are provided to learn more about MVP+C and its technologies.

MVP+C. Background
Programming, at its core, is about data transformation. And the case for
most mobile applications, it is about data transformation, data composition,
and UI presentation

MVP+C. What is the C?
C is for Composer.

RxJava
Do not use Rx if there is no “event”.

Dagger
Make your class loose coupling between other class.

Data source
● Server
○ Handle the communication to server using Retrofit
○ Every request call to server MUST handle error
● Local
○ Save data into local
■ Shared Preference
■ DBFlow

Error handling
Railway Oriented Programming

Error handling
● Kinds of error:
○ NetworkError
○ NoInternetError
○ TokenExpiredError
○ UnknownError
○ ResultEmptyError
● All Error passed to composer

The document discusses using the Model-View-ViewModel (MVVM) pattern to maximize code reuse across platforms when building native apps. MVVM separates an app's view logic from its user interface code, allowing the view logic to be shared while keeping platform-specific UI code separate. This approach allows most of an app's model and view model code to be written once and shared across platforms like iOS and MacOS when using Xamarin. The document provides an example of how an internal support app called Halp was built with shared view models and platform-specific views for Mac and iPhone apps. Some challenges of applying MVVM in Cocoa are also discussed.

A Cluster-Based Trusted Secure Multipath Routing Protocol for Mobile Ad Hoc N...IJCNCJournal

Mobile Ad Hoc Network (MANET) is a self-organizing and flexible system. MANET systems manage sensitive data from many distinct applications in various domains. Its dynamic nature increases its vulnerability to numerous types of security threats. Many of the present approaches using indirect approaches provide false approximations of trust degrees. It is significantly required a good routing system that meets Quality of Service (QoS) standards and enhances network performance. In this paper purposed cluster-based trustworthy safe multipath routing (CTSMP-Routing) for mobile ad hoc networks (MANETs). Load balancing challenge is addressed by using a modified proportional topology optimization (MPTO) approach using geographical data related to network nodes. The Enhanced Seeker Search Optimization (ESSO) approach is used to compute trust degrees after the clustering phase considering numerous network constraints including node mobility, received signal strength, energy consumption, and cooperation rate. Assumed to be the service node, the node showing the highest degree of trust manages inter-cluster routing. We have developed a hybrid soft computing approach termed the multi-layer deep recurrent neural network (ML-DRNN) to enhance the optimal path-finding process. This method selects, among many routes between source and destination nodes, the best one quickly. The outcomes of this paper demonstrate that CTSMP-Routing provides effective protection against several attack paths within the MANET environment and displays better performance in regard to quality of service (QoS) requirements.
