AAMple-G Reader – PDF reading application

Abstract - In recent years, with the rapid development in technologyand thepopularityofmobileintelligentterminals (such as smartphones,tablets,etc.),mobile learning beginsto rise and attracts widespread attention. Mobile learning is a new form of learning using wireless mobile communication network technology and wireless mobile communication devices(suchas mobilephones,PDA,PocketPC,etc.) toobtain education information, education resources and education services.Thecharacteristicsofmobilelearningdeterminethat it has unique advantages compared with traditional education,includingthefollowingcharacteristics:(1)Readers can read anytime and anywhere; (2) Readers can make full use of trivial time to learn; (3) It can meet readers personalized learning needs. Mobile phone is the most importantcarrierofmobilereading,currentlythefunctionsof reading apps in the platform is gradually becoming perfect, but they still have some shortcomings such as unable to display meaning of a word within the app itself, not tracking users reading progress and text-to-speech for given content. Tocatertheseproblems,wehavesetouttodevelopareading app. It has inbuilt feature to display the meaning of a word and also provides various user-friendly functionalities which improve users’ experience. The app is developed with appropriate system configuration and Android Studio framework.

3.1 Annotations

To implement annotations in a PDF reader in Android Studio,youcanfollowthesesteps:

Use a PDF library: There are several open-source PDF librariesavailableforAndroid,suchasPDFBox,iText,and MuPDF.Choosealibrarythatsuitsyourneedsandimportit intoyourAndroidStudioproject.

CreateaPDFviewer:YoucancreateaPDFviewerusinga WebView, or you can use a library that provides a PDF viewercomponent.YoucanaddthenecessaryUIelements, suchasnavigationcontrolsandzoomcontrols,totheviewer.

Add annotation functionality: To add annotation functionalitytothePDFviewer,youcanusetheannotation featuresprovidedbythePDFlibrary.Youcanaddtheability tohighlighttext,underlinetext,addnotes,anddrawshapes.

Storeannotations:Youneedtostoretheannotationsmade bytheusersothattheycanberetrievedlater.Youcanusea localdatabase,suchasSQLite,tostoretheannotations.You cancreateatabletostorethePDFfilename,pagenumber, annotationtype,coordinates,andannotationtext.

Retrieve annotations: When the user opens the PDF file again, you can retrieve the stored annotations from the databaseanddisplaythemonthePDFviewer.Youcanuse the PDF library's annotation features to draw the annotationsonthePDFpages.

Edit and delete annotations: You can allow the user to edit and delete annotations by selecting them and providing an editing interface. You can update the database with the changesmadebytheuser.

By default each annotation type has an associated tool to allow you to create those annotations. When creating a custom annotation you'll need to create an associated annotation tool to define how the user can create that annotation.

Annotation tools handle interactions by receiving touch and gesture events. When touch & gesture are made, PDFViewCtrl sends corresponding event to ToolManager. ToolManager passes event to current tool which perform specifiedfunctions.

3.3 Hyperlink

Hyperlink function allows users to navigate through digital documents by clicking on links that take them to other locations within the same document or to different documents or websites. To implement hyperlink functionality in a PDF reader in Android Studio, you can followthesesteps:

3.2 Text-To-Speech Feature

The Text-to-Speech function is a technology that allows a device to read out written text in a synthesized voice. It involves the user inputting text into a text field, selecting a language, and the text being analyzed by the TTS engine to identify the correct pronunciation, pitch,andemphasisofthe words and phrases. To implement text to speech functionality in a PDF reader in Android Studio, you can followthesesteps:
