A proposal of Android Programming Learning Assistant System with implementation of basic application learning

Abstract

Purpose With rapid increase of Android devices and application systems, there is a strong demand for Android application programmers. A lot of schools are offering Android programming courses to meet this demand. However, Android programming can be different from the conventional one because it needs interactive functions through interfaces with users, which makes the study more difficult. This paper aims to propose an Android Programming Learning Assistance System, namely, APLAS, to assist the Java-based Android programming study and education. Design/methodology/approach By adopting the test-driven development method, APLAS is designed to achieve independent learning without the presence of teachers. Using JUnit and Robolectric, the answers from the students are automatically marked in APLAS. To cover extensive materials in Android programming, APLAS offers four stages where each stage involves several topics. Findings To evaluate the effectiveness of APLAS, we implemented the Unit Converter assignment that covers the first two topics, namely, Basic user interface in the first stage and basic activity in the second stage. Through solving the assignment, it is expected to learn basic application development. Forty novice students of an IT department in Indonesia were asked to solve both topics separately. Originality/value The results show that APLAS is useful and helpful for the self-study of Android programming, as they could complete codes with good execution performances.

A Proposal of Advanced Widgets Learning Topic for Interactive Application in Android Programming Learning Assistance System

“…The average time to complete the eight tasks was 225 minutes. They exhibit the great improvement in reducing the time to develop the more complex Android application from the previous results in [7].…”

“…To solve the difficulties in Android programming courses, the assisting system for students to learn Android programming by themselves is helpful. Therefore, we have proposed an Android Programming Learning Assistance System (APLAS) [7] as the platform for this self-learning of Android programming.…”

“…In this paper, we propose an Advanced Widgets learning topic in Interactive Application stage in APLAS. This topic can be studied after the previous two topics, Basic UI and Basic Activity [7]. This topic places emphasis on the study of building an interactive UI, including the utilization of modified Widgets, ViewGroup, Widgets Style, UI Theme, a notification Widget (Toast), and Timer class.…”

A Static Assignment Algorithm of Uniform Jobs to Workers in a User-PC Computing System Using Simultaneous Linear Equations

“…For evaluations of the proposal, we consider uniform jobs in the three applications for the UPC system, namely, OpenPose [3], OpenFOAM [4], and code testing [5,6]. For OpenPose, the CNN-based program runs with 41 images of human bodies.…”

A Proposed Framework of Campus-Oriented Online Text Messaging System

“…In this paper, we proposed a framework that can be used to implement online text messaging that is specifically used for campus purposes. A campus has specific and continuous activities, such as teaching activities carried out by teachers to students, and research discussion activities between teachers and students [8]. Moreover, this framework can be integrated with existing campus systems, so that the required information can be shared with each other.…”
