Blogger

An offline-first Android blog drafting and publishing suite featuring SQLite persistence, internal image storage isolation, FileProvider social sharing, and multi-select bulk operations.

---

📖 Overview

Blogger is a distraction-free, offline-first mobile blogging studio and markdown/article drafting companion for Android. Designed for writers, journalists, and content creators who need to compose, archive, and refine articles on the move without dependence on cloud backends or active internet connections.

The application couples a native SQLite database architecture with the Android Jetpack MVVM pattern. It features an isolated media pipeline that saves selected cover photos to private internal storage, secure system-wide article sharing via FileProvider, real-time title search filtering, and contextual multi-select deletion modes.

Key Highlights

• 100% Offline Article Drafting: Create, edit, and organize posts with zero server requirements.
• Private Media Isolation: Imported gallery images are safely copied into private app internal storage, protecting against broken external image URIs.
• Rich Social Sharing: Dispatches formatted post text and attached image media via Android's native share sheet using secure FileProvider URI grants.
• Multi-Select & Bulk Actions: Long-press to activate multi-select mode and batch delete archived drafts.

✨ Core Features

✍️ Distraction-Free Article Editor

• Compose articles with custom title, expandable body content, formatted date-time stamps, and custom cover images.
• Full editing and updating capabilities for previously drafted blog entries.

🖼️ Private Media Sandboxing

• Automatically copies selected gallery photos to internal sandbox storage (getFilesDir()), preventing media links from breaking if original files are moved or deleted.
• Image loading optimized via Glide with rounded corner transformations and placeholder fallbacks.

📤 Secure Article Sharing (FileProvider)

• Broadcasts full article text alongside the attached image file to third-party social apps, messaging platforms, and note repositories using FileProvider content URIs.

🔍 Real-Time Search & Multi-Select Batch Delete

• Built-in SearchView filters the article archive in real time by title matches.
• Long-press contextual multi-selection enabling one-tap bulk deletion of multiple drafts.
