2 Online Compilers for Android Using Mobile Cloud Computing 1. INTRODUCTION Cloud computing can be used to improve the organization growth. It provides shared computer processing resources and other devices on demand. Users can access their resources from anywhere in the world using smartphones. Users can access the data at any time using their smartphones. They can use the single application on multiple platforms. No need to have different applications for different platforms. Cloud computing makes the work of developers easier by managing the security, data availability, cross-platform support. Fonts, spacing, and related information for producing the proceedings manuscripts Together with a touchy development of the versatile applications and rising of distributed computing idea, portable distributed computing (MCC) has acquainted with being a potential innovation for portable administrations. MCC coordinates the distributed computing into the mobile condition and defeats impediments identified with the execution (e.g., battery life, stockpiling, and data transmission), condition (e.g., heterogeneity, versatility, and accessibility), and security (e.g., dependability and protection) examined in versatile processing. Smartphones do not have enough hardware resources like CPU, memory, etc. It is a time-consuming activity to run a small program on smartphones. It also requires much memory to run a program. Some of the programs cannot run in Android system due to its different architecture from other platforms. So users need a separate application which can execute a program implemented using different programming languages like C, C++, JAVA and other languages. Online compilers make the compilation of the program easy by compiling the code in cloud virtual machines. Cloud provides different virtual machines for various purposes like installing applications, providing servers, etc. Users no need to have the systems with them to compile the code. By using smartphones itself, they can compile their code. Online compilers make the compilation of the program easy by compiling the code in cloud virtual machines. Cloud provides different virtual machines for various purposes like installing applications, providing servers, etc. Users no need to have the systems with them to compile the code. By using smartphones itself, they can compile their code. By installing this application on their smartphones, they can do the actions like, Create, save, update and upload the code. This application will provide all these functionalities to the user with real intensity. Currently, different compilers should be installed on the user's system to run different programming languages. It is a time-consuming activity to execute the command prompt and command actions to compile the program. Users should know about the commands to compile the programs. Users cannot take the laptop with them all the time to compile the programs. Using smartphone users cannot compile the programs. So by implementing cloudbased compilers for Android, these problems can be resolved. It was running locally on the machine so users cannot access the system anywhere they need. Users cannot access the saved programs at any time. To run a simple program every time they require a system with them. Without the system, they cannot compile the program. It also requires a lot of external resources like memory, CPU to run the program on the local machine. 2. RELATED WORKS A review by (Kumar et al.,2014) with the high expanding of information calculation in business and science, the limit of information handling has considered as a key asset in numerous nations. Portable distributed computing (MCC), as an advancement and augmentation of versatile registering (MC) and distributed computing (CC), has acquired the high portability and adaptability. Online IDE can be used to compile the programs without editor@iaeme.com

3 Vijayan R, Mareeswari V, Gunesekaran G, Balasubramanian V and Senthil Kumar R using the command prompt and user command input. By ing the code to other users, they can share their programs. Online IDE acts as editor for the user. It can be used to create, update, save, and delete the files in online. IDE will upload the code to the cloud and compile it and returns the results to the users. Here (Gadhikar et al.,2012) users can store their program in the cloud for better access. Browser-based can be used to compile the programs without command prompt and command actions. It makes compilation and implementation of programs easier. The user should have a good internet connection to open the IDE in the browser. It can compile only Java programs. Users cannot compile another programming language like C, C++, Python, and PHP. The IDE should be good responsive UI for the users to use it Now the days each and users are moving to Cloud for better and faster access to the data. Cloud computing provides different services for actions like Storage, Operating Systems, Machine Learning, Security, etc. Users need compilers installed in their machine to run the programs. Different compilers are expected to run different programming languages. Cloud computing provides compilers in online for the users. So that users can run their programs at any time they need. This system can be used at any stage by the user to compile their program online.here the author provides (Datta and Paul,2014) the online storage for the users of their programs online so that they can use their program at any time. Separate Virtual machines utilized for each compiler. It is time-consuming activity at a run a chance to select the virtual machine to execute the current program. Now the days all the applications are moving to the cloud for the better enhancement of the applications. In this web application user can create a group of members to access the same file. By accessing the same file, a collaboration between the users will occur. The web application also provides the functionality like sharing the code with other users etc. In ( Rohini and Hadap,2014) can be used to compile the programs online. It provides the functionality to share their code with other users. The Web application shares the new concept to access the same with a group of users. Users need FileZilla, Putty applications to upload there in the cloud to access the same file between users. Users need an internet connection to open this web application. Different type of attacks is there to affect a user's cloud data. To avoid such threats to the data encryption methods can be efficiently used. The encryption methods for the cloud computing provides different throughput, the response time for various methods. Here in (Singh and Kaur,2015; Arora and Parashar,2013), each method will have their advantage and disadvantage. The throughput, response time encryption and decryption methods used in the proposed system. There are different cloud service providers available in the market. Each cloud providers are using various strategies and technologies. Here in (Chandra et al.,2015; Bhondave et al.,2016)[7-8] the online web-based Java compiler can be used to run the programs like C, C++, JAVA They are using WSDL, SMTP, XML scripts for the transaction of the data with the application. It provides good UI design to the user to implement their code in online. Using WSDL, SMTP, XML scripts for the application is no need when the user can access the cloud by deploying Amazon web services. Authors (Idnani et al.,2015)] gave a compiler conveyed on cloud and their entrance through Android Smartphone and the web. In this framework, the cloud would incorporate compilers for Java, C, and C# code. The framework would incorporate the program, and if no blunders discovered, it will begin executing the program. Numerous software engineers can exploit the capacity to utilize compiler application on cell phones. Therefore, empowering them to effortlessly get to, change and order the code and evacuating blunders in a hurry. That will exchange the duty of establishment, redesign, and support of compilers from clients to cloud compiler specialist organizations editor@iaeme.com

4 Online Compilers for Android Using Mobile Cloud Computing In (Mohammed and Hamada,2016) online form of the application is additionally accommodated clients who do not utilize Android gadgets that gotten to using a program on a PC or Smart gadget. The framework uses a current online compiler. The created cloud-based compiler coordinated into a keen interactive media learning framework but a limited number of compile time and no execution for GUI programs. The author introduces (Pawar et al.,2015) C/C++/JAVA compilers which make it easy to compile and execute programs anytime anywhere by using their Android smartphone. (Patil and Ingale,2015)Authors present the simple interface to the client through the Android-based gadgets. Android-based structure interface introduced on the client's Android gadget through which they can without much of a stretch get to the administration. An (Abdulla et al.,2015)private cloud on which the product would facilitate. The product would give to the end client utilizing a SAAS cloud. The product would contain a framework that has a content tool and a terminal. The client would give a choice to choose the dialect in which he needs to order the program. The product will arrange the program and restore the yield to the client. Extra functionalities, for example, checking of the framework, client utilization, client gatherings, and collective improvement can be included as required. Here (Pabitha et al.,2013) fundamentally focuses on the learning group by giving an efficient cloud compiler as SaaS. By blending the two unique ideas called distributed computing and open source which reduces the inconveniences of versatility, similarity, power, and storage room by making utilization of the concept of cloud compiler. The basic hidden design to convey a cloud compiler is the foundation of private cloud under Linux condition, which gives facilitated administrations to a set number of individuals and the administration dispersed in a heterogeneous way. 3. ONLINE COMPILERS FOR ANDROID USING MOBILE CLOUD COMPUTING The proposed work contains five modules. Each module contains different functionalities Android application This module provides the users to access the feature of the project. Users can type their code, edit, open and save their code in the cloud using Android application. They can compile the code using application and can see the output on the console. Any error occurs in the code shown on the console on a compilation of the program. Users can also provide feedback about the services to the admin. The user can make the program public so that everyone can access the program Cryptography This module uses the encryption and decryption algorithm to encrypt and decrypt the data. To provide security to the user credentials, we are encrypting the data and storing it on the backend. It receives the input from the user and it will encrypt the data and will save in the cloud backend. When users want to open the code, it will be decrypted and shown to the user editor@iaeme.com

Cloud Compiler The main module of this approach where the user can upload their code to the cloud and compile it using their smartphones. It will get the input code from the user and compile based on the programming language chosen by the user. After compiling it will post the output to the user. After compiling the code uploaded by the user contains error means it will post that results to the output console following with the error Output and Error Diagnose This module will receive the output from the cloud compiler and will show the output to the user. The user can display the output of the program in this console. The errors on the code also will be shown after compiling the code in the cloud compiler. The user can provide the inputs to the output console via input console so that it will receive input from the user and shows the output File Access Methods There are different file modes are available for reading, write only, read and write, etc. Here users can choose the file mode like the public, private, protected. If the public mode were chosen means it would access by all users at the same they can give the access modes to the file like reading only, read and write. It will act as a Repository for the users to collaborate with each other. Anyone cannot access the files which are made by private. The proprietor who uploaded the program can only access that program. Protected mode files can access by the friends of the registered users. To access the protected mode files, they should be friends of the proprietor who uploads the program and also they should be a validly registered user with the application. Blowfish algorithm is used to encrypt and decrypt the data. Blowfish contains 64-bit block size and a key length ranging from 32bits to 448bits. There are 16 rounds in blowfish algorithm and uses large key-dependent S-boxes. The 16 rounds called as Feistel cipher. The algorithm maintains an 18-entry P-array and 256-entry S-boxes. S-boxes produce 32-bit output and accepts 8-bit input. Each P-array entry is used in each round as once, once the final round reached half the data block is XORed with one of the two remaining P-entries. F function splits the 32-bit input data into Four quarters where each quarter contains 8-bits editor@iaeme.com

6 Online Compilers for Android Using Mobile Cloud Computing These quarters gave as input to the S-boxes. The output is added with modulo 232 and XORed to produce the outcome. 4. IMPLEMENTATION USING ANDROID STUDIO The work is emulated using Android Studio with Dynamo DB deployed in Amazon web server. The following is a sequence of steps operation Step1: Create an account Step 2: Step 3: Step 5: Step 6: Step 8: Step 9: Step 10: Sign in into the application using credentials and If the user wants to create a new file go to step 3. Then upload a file to cloud and proceed to step 8, open a file from local go to step 9, open file from cloud proceeds to step 10, search for the file in cloud proceeds to step 16, search for the file in local go to step 15. Create a new file by selecting the programming language, Enter the code and run the code Once user press the run button file saved and it will send to the cloud for execution process goes to step 11. Receive the Output, Error, Warnings from the API and set it to the output. Monitor the output console for the error and output. Select the file to upload to the cloud with appropriate access privilege and file access mode. Open the file from the local database. Do the modifications in the code. Repeat the step 4,5 and 6. Open the file from the cloud. Check with file access method and file access privileges and If the user is permitted to read the file go to step 4,5 and 6. Step 11: Step 12: Step 13: Step 14: Step 15: When the user is authorized to read and write the file. Open the file in the editor and do the modifications and repeat the step 4,5 and 6. Check which the user has chosen programming language by checking the extension of the file, Call the appropriate code to run the program. Check for the warnings and error, Return the Output, Error, Warning to the application Get the filename from the user and scan it with the database. If the file found go to step 10. if not show to user file not found the error. Get the filename from the user and scan it with the local database.
