MiniiChat v1.0.2

Dark mode legibility fix, stable signing for in-place upgrades, and two new feature groups.

Install

miniichat-1.0.2-arm64-v8a-release.apk for most modern phones (recommended), or miniichat-1.0.2-armeabi-v7a-release.apk for older 32-bit ARM.

v1.0.2 onward uses a stable signing certificate, so future upgrades install in place without needing to uninstall first. Upgrading from v1.0.0 / v1.0.1 still requires one final uninstall because their signatures were ephemeral.

Dark mode

• Tightened the static dark palette: lighter onSurfaceVariant, stronger surface contrast for chips, hints, and dividers
• Material You dynamic color in dark mode now overrides the legibility-critical roles, so wallpapers that produced low-contrast text no longer turn body copy nearly black

New feature: per-provider HTTP customization

• Provider editor is now a full-screen page (was a cramped dialog)
• Advanced section adds key/value editors for custom HTTP headers and extra body params — lets you set things like OpenRouter's HTTP-Referer, Anthropic's anthropic-version, or any provider-specific JSON option
• Saved values are sent on every /chat/completions and /models request

New feature: message actions (long press)

• Long-press any message to open a menu
  • User: Copy / Edit / Regenerate from here / Delete
  • Assistant: Copy / Delete
• Inline edit mode rewrites the message in place
• "Regenerate from here" branches the conversation: drops everything after the chosen user message and re-runs

Build

• versionCode 7 / versionName 1.0.2
• ABI splits: separate arm64-v8a and armeabi-v7a APKs
• Stable signing keystore committed to the repo (public OSS signature)
• GitHub Release attaches release APKs only

MiniiChat v1.0.1

Bug-fix release. Two release APKs: arm64-v8a (most modern phones, recommended) and armeabi-v7a (older 32-bit ARM devices). Pick whichever matches your device.

Bug fixes

• Editor state leak — editing one provider/assistant then another no longer shows stale data
• Chat scroll thrash — list no longer animates on every streamed token
• DataStore I/O during streaming — UI updates in-memory each token; persistence throttled to 250ms
• Settings two-way binding — slider / system prompt no longer drop input on rapid changes
• Send debounce — re-entrant taps while a stream is in flight are now ignored
• Regenerate keeps attachments — re-running a message no longer drops the user's images / files
• Attachment OOM — 10 MB hard cap with streaming size guard, oversize files rejected with a Toast
• Assistant delete button — now properly disabled (greyed out) when only one assistant remains
• Error dialog — only offers "Open Providers" when the error is actually about provider config; otherwise just OK
• i18n leftovers — drawer date headers ("Today / Yesterday / Previous 7 days / 30 days / Older") and Settings section headers now use string resources, so Chinese mode no longer shows English text
• formatBytes — 1-decimal precision (1.5 KB instead of "1KB")

Build

• versionCode 6 / versionName 1.0.1
• ABI splits: separate APKs per architecture
• APK filename: miniichat-<version>-<abi>-release.apk
• GitHub Release attaches release APKs only; debug builds remain a CI artifact

MiniiChat v0.4.2 — bug fixes + media attachments

Bug fixes (from v0.4.1 testing)

• Streaming flag clears immediately after AI reply finishes — no more waiting a few seconds before sending the next message
• Preset selection no longer overwrites your typed Base URL / Name. The preset URL becomes a placeholder and is used only when the input is left empty
• Provider model lists collapse after 5 entries, with Show more / Show fewer

New: media attachments

• New + button in input bar with Image / File submenu
• Picked attachments shown as removable chips above the text input
• User bubble renders attachment chips above the text bubble
• Image attachments sent as base64 data URLs in OpenAI-compatible multipart content (works with vision-capable models like gpt-4o, gemini-1.5, claude-3.5-sonnet)
• File attachments inlined as text references for non-vision models

Min Android 8.0 (API 26).

MiniiChat v0.4.1 — bug fixes

Fixes for issues reported in v0.4.0.

• Auto-append /v1 to provider base URLs missing a version suffix on save
• Remove unused + button from input bar (was a no-op placeholder)
• User messages now render as right-aligned chat bubbles (social-app style); assistant keeps avatar + full-width markdown
• System back button navigates up properly: drawer closes drawer, model picker dismisses, Providers/Assistants returns to Settings, Settings returns to Chat, only exits the app from the Chat root

Min Android 8.0 (API 26).
