With the development of Android OS, an open source operating system has created an android world and enhance the software development skills, where developers are creating new application for Android devices.Application are typically developed using Java programming language using the Android Software Development Kit but another languages such as Python being dynamically typed is more preferable nowadays compared to Java.Here we created an Offline Android Application-Appointment Scheduler and Location Helper using File operation.Moreover in this application user can schedule his appointment and the user can get to know the path and direction of any nearby places by Location Helper. I. Introduction: Python:Python is a dynamic typed,multi-paradigm programing language created by Guido Van Rossum.It almost run on every operating system such as Win, Linux/Unix, Mac, OS/2 etc. Python has a large standard Library which is one of the greatest strength of this high-level language as it provide tools for achieving various task in a flexible manner. Python over Java:Python is easy to learn, use and read compared to Java.Significantly, Python programs are shorter compared to Java.Due to the dictionary feature and list"s flexibility of python it has been easy to achieve task with less complicacy.Python also allows run-time typing. Android Operating System:Android is open source based Linux kernel operating system mostly designed for touchscreen for mobile devices such as mobile phones and tablet computers.Android is known to be the best operating system and the fastest emerging one, with user-friendly GUI, open to all with lots of application and amazing features. Scripting Layer for Android:Scripting Layer for Android (sl4a) is a library, designed for developers, for creating and running of scripts written in various scripting languages directly on Android devices.Scripts can access Application Programming Interface (API) which is library, usually a set of classes with set of function assigned for performing different works, also specifying the interaction between software components. Motivation:As the development of Android is at rapid pace with various online application which uses database for storing relevant information of users and comes with a problem that once in a while user may not have an internet access which makes an application idle with no use and henceforth android users search for Offline applications.Taking this problem into consideration, we intent to design an Android Offline Application-"Appointment Scheduler" and "Location" using File Operation instead of database.Moreover, we have work in various features on the application using files to store users" relevant information and we have used our algorithm for fetching information from a file using various types of file operation.
