Power consumption is a major factor to be taken into consideration when using mobile devices in the IoT field. Good Power management requires proper understanding of the way in which it is being consumed by the end-devices. This paper is a continuation of the work in [1] and proposes an energy saving API for the Android Operating System in order to...

The 21st-century skills are the answer to the world of education in welcoming the industrial era 4.0. Indonesian language teaching materials for the Vocational High School (SMK) level also need to adapt to this approach. Synchronizing the SMK curriculum with industry certainly brings advantages for preparing anecdotal text teaching materials, especially animation skills. This research and development using the 4D method, seek to create prototypes of teaching materials that apply 21st-century skills assisted by Google Sites. The research stages consist of initial research and information gathering, product foundation and planning, and product format development. The product testing stage is not carried out. Teachers have difficulty completing the material because learning hours are often used for vocational activities. The application of 21st-century skills in anecdotal teaching materials is as follows: (1) critical thinking is applied to activities to identify structure and language; (2) communication is carried out by presenting the idea to be uploaded through social media; (3) collaboration with group activities in writing anecdotes based on comic strips; and (4) creativity and innovation in compiling anecdotal texts based on comic strips in the order given.
... With Enersave API [20], the authors circumvent the problem by suggesting to developers to use a specific API instead of the genuine Android API.

Nowadays, energy efficiency is recognized as a core quality attribute of applications (apps) running on Android-powered devices constrained by their battery. Indeed, energy hogging apps are a liability to both the end-user and software developer. Yet, there are very few tools available to help developers increase the quality of their native code by ridding it of energy-related bugs. Android Studio is the official IDE for millions of developers worldwide and there's no better place to enforce green coding rules in everyday projects. Indeed, Android Studio provides a code scanning tool called Android lint that can be extended with lacking green checks in order to foster the design of more eco-responsible apps.

... Turning off the GPS as the user enters an indoor environment reduces power usage and, knowing the points near the exit, the model can turn it on again without losing any position information. Even with a weak signal, Wi-Fi usage can be used efficiently over 3G or 2G networks to reduce power usage [30], thus, alongside the GPS, the power usage can be brought down by not using these connections. The model reduces power consumption as a positive side effect of transition states management. ...
The adaptability between different environments remains a challenge for Mobile Augmented Reality (MAR). If not done seamlessly, such transitions may cause discontinuities in navigation, consequently disorienting users and undermining the acceptance of this technology. The transition between environments is hard because there are currently no localization techniques that work well in any place: sensor-based applications can be harmed by obstacles that hamper sensor communication (e.g., GPS) and by infrastructure limitations (e.g., Wi-Fi), and image-based applications can be affected by lighting conditions that impair computer vision techniques. Hence, this paper presents an adaptive model to perform transitions between different types of environments for MAR applications. The model has a hybrid approach, choosing the best combination of long-range sensors, short-range sensors, and computer vision techniques to perform fluid transitions between environments that mitigate problems in location, orientation, and registration. To assess the model, we developed a MAR application and conducted a navigation test with volunteers to validate transitions between outdoor and indoor environments, followed by a short interview. The results show that the transitions were well succeeded, since the application self-adapted to the studied environments, seamlessly changing sensors when needed.

The proliferation of cellular network enabled users through various positioning tools to track locations, location information is being continuously captured from mobile phones, created a prototype that enables detected location based on using the two invariant models for Global Systems for Mobile (GSM) and Universal Mobile Telecommunications System (UMTS). The smartphone application on an Android platform applies the location sensing run as a background process and the localization method is based on cell phones. The proposed application is associated with remote server and used to track a smartphone without permissions and internet. Mobile stored data location information in the database (SQLite), then transfer it into location API to obtain locations result implemented in Google Maps. Track a smartphone with fixed identifiers mostly SSN (SIM (Subscriber Identity Module) Serial Number) and IMEI (International Mobile Equipment Identity) derived from an identifying string unique to the user's device. The result located place is Moderate correct according to the (GSM) and (UMTS) cellular networks which is used for obtaining location information.
