BookMaster Android Ebook App Builder

BookMaster – Ebook App Builder

Convert DOCX, HTML, and selectable-text PDF documents into polished standalone Android ebook apps through one complete desktop-to-mobile workflow.

BookMaster is a cohesive ebook app-building product that combines a reusable native Android reader template with a companion desktop generation utility. The desktop utility prepares the book content, SQLite database, chapter structure, cover artwork, metadata, package configuration, and app module used by the mobile reader. Both components are built to work together as one complete product rather than as separate, unrelated applications.

BookMaster is designed for authors, publishers, educational-content creators, agencies, and Android developers who want to transform existing documents into modern branded ebook applications without repeating the same database and project-setup work for every book.

Prepare Content → Convert Document → Review Chapters → Generate Module → Build App → Publish

Product Cohesion & Architecture Overview

Why BookMaster is One Single Cohesive Mobile Application Product:

BookMaster is categorized under Mobile Applications / Android as a complete native Android Ebook Application Generator. The Windows desktop generation utility (BookModuleWizard) and the native Android reader engine (:engine) are not separate or competing products—they form two essential, interdependent components of one unified application publishing workflow:

Exclusive Schema Alignment: The desktop utility parses raw DOCX, HTML, and PDF documents specifically into the Room SQLite database schema (book_pages, book_pages_fts) and metadata structure required by the native Android reader engine.
Automated Android Code Generation: The desktop utility builds the exact Kotlin dependency-injection config (AppConfig.kt), asset placements, cover WebP assets, and Gradle module manifests that the native Android Studio project imports.
Interdependent System Functionality: The desktop utility cannot produce final standalone apps by itself (it generates an Android Studio source code module), and the Android reader template cannot render books without the database and configuration produced by the desktop tool.

Together, these two components form a seamless desktop-to-mobile toolchain that allows authors, publishers, and developers to generate unlimited custom Android ebook apps for Google Play.

A Complete Android Ebook Reader — Not Just a Basic Template

The generated Android application includes a complete reading experience built with Kotlin, Jetpack Compose, Material Design 3, Room, and SQLite FTS4. It is designed to feel fast, modern, responsive, and comfortable on both phones and tablets.

Search & Content Discovery

Fast Full-Text Search: Room and SQLite FTS4 indexing provide fast search across large books and thousands of content entries.
Contextual Search Results: Search results display the matching text in context, helping readers understand where and how a word or phrase appears.
Search History: Previous searches are saved locally so readers can quickly return to recent topics without typing them again.
Jump-to-Result: Selecting a result opens the exact matching page or content location instead of forcing the user to search manually.
Chapter Navigation: An interactive Table of Contents allows readers to move directly between chapters and sections.

User Personalization & Reading Tools

Interactive Text Highlighting: Readers can select important passages and save highlights using multiple color choices.
Bookmark Management: Save important pages, review saved bookmarks, and return to them through a dedicated bookmark interface.
Personal Reading Notes: Users can attach their own notes to selected content and keep them available for future reading sessions.
Reading Progress: The app remembers the last opened location and tracks reading completion progress.
Typography Customization: Readers can adjust font size, line spacing, and font family to create a more comfortable reading experience.

Flexible Themes & Visual Customization

Light Mode: A clean, bright reading experience for daytime use.
Dark Mode: A comfortable low-light interface designed for night reading.
System Mode: The app can automatically follow the device theme.
Multiple Color Palettes: Included palette options allow the reader interface to match different books, brands, and reading preferences.
Material Design 3: Modern components, smooth transitions, and a consistent native Android experience.

Adaptive Phone & Tablet Layouts

The interface adapts to different screen sizes and orientations. BookMaster supports compact phone layouts as well as expanded tablet layouts, providing a more natural reading experience across supported Android devices.

Offline-First Reading

The entire book is stored locally inside the application, so readers can access the content without an internet connection. User data such as bookmarks, highlights, notes, search history, preferences, and reading progress is also stored locally on the device.

No internet connection is required to read the book
Fast local content loading
Bookmarks and highlights remain available offline
Reading preferences are preserved between sessions
No external book-content server is required

LTR & RTL Language Support

BookMaster includes dedicated starter templates for Left-to-Right and Right-to-Left reading experiences. The package includes an English LTR template and an Arabic RTL template, making it suitable for English, Arabic, Hebrew, and other supported languages.

Important: Text-to-Speech and audio playback are not included in the current version.

AdMob-Ready Monetization

The Android reader is already prepared for Google AdMob monetization. Buyers can replace the included test or demonstration identifiers with their own AdMob account information and configure advertising from the central app settings.

Banner Ads: Ready-to-configure banner placements inside the reader experience.
Interstitial Ads: Ready-to-configure interstitial placements for suitable navigation points.
Central Ad Configuration: Manage advertising identifiers and enable or disable ads from one configuration area.
Google UMP Integration: Includes Google User Messaging Platform support for consent-message workflows.
Test and Production Setup: Documentation explains how to use test IDs during development and production IDs before release.

The final publisher is responsible for configuring their own AdMob account, consent messages, privacy policy, Google Play disclosures, advertising declarations, and applicable regional requirements.

Why Choose BookMaster?

One Cohesive Product: The desktop utility prepares the content and project files used by the included Android reader template.
Reusable App-Building Workflow: Create different book projects with their own content, branding, package namespace, cover, and configuration.
Less Repetitive Work: Reduce manual database creation, file placement, cover processing, and module-configuration tasks.
Multiple Source Formats: Import DOCX, HTML, and selectable-text PDF documents.
Modern Native Codebase: Built with Kotlin, Jetpack Compose, Material Design 3, Room, Hilt, and MVVM-based architecture.
Offline-First Reader: Book content and reader-generated data remain available locally without requiring a remote backend.
Publisher-Friendly Customization: Configure titles, author information, package IDs, covers, themes, typography, advertising, and reader behavior.

Important Product Notes

BookMaster prepares the content, database, and Android module. Android Studio is still required to test, sign, build, and publish the final application.
Output quality depends on the formatting and structure of the source document. Complex documents may require preparation or cleanup before conversion.
Scanned or image-only PDFs may require external OCR processing before they can be imported as selectable text.
Buyers must replace demonstration package names, book content, covers, icons, advertising identifiers, privacy links, and sample configuration before publishing.
Google Play approval is controlled by Google and cannot be guaranteed by the item author.
The software does not impose an internal project-generation limit. Each published or distributed final application must follow the applicable Envato license and third-party platform requirements.
Preview books, covers, logos, screenshots, and demonstration content are not included unless specifically identified as part of the downloadable package.
Text-to-Speech and audio playback are not included in the current version.
