v0.1.1 preview

Touch fixes for OrcaSlicer for Android.

Fixed

• Pinch to zoom is reliable. A second finger could be dropped by Qt after it landed, so a pinch, often a zoom-out, sometimes did nothing until the Back button was pressed. The 3D view now keeps both fingers in every case.
• Pinch zooms toward your fingers, like other touch apps, instead of toward the screen centre, so the model stays under your fingers.
• Long press no longer swallows pinches. If the second finger landed late, the context menu used to open; it now opens only when you lift a finger you held still.
• The app has the real OrcaSlicer launcher icon.

Which APK?

• OrcaSlicer-android-arm64-preview.apk: phones, tablets and foldables.
• OrcaSlicer-android-x86_64-preview.apk: emulators and x86 Chromebooks.

Installs as an update over 0.1.0 (version code 2). Requires Android 9+ and OpenGL ES 3.0.

Tip: if object names float over your models, that is Show Labels. Long-press the empty plate and untick it.

v0.1.0 preview

First public preview of OrcaSlicer for Android: OrcaSlicer's own slicing engine and wxWidgets interface, running natively on Android. It is not a companion app or a rewrite. Based on OrcaSlicer 2.5.0-dev (1ee0b730).

Which APK?

• OrcaSlicer-android-arm64-preview.apk: phones, tablets and foldables (almost every device since 2017).
• OrcaSlicer-android-x86_64-preview.apk: emulators and x86 Chromebooks.

Requires Android 9+ and OpenGL ES 3.0. The APKs are signed with a development key, so Android will ask you to allow installing apps from your browser or file manager.

Highlights

• Prepare, gizmos (move, rotate, scale and the rest), all settings and presets, slicing, and the Preview legend and layer sliders.
• Touch input:
  • Tap to select, drag to move or orbit.
  • Long-press for context menus.
  • Two fingers pinch to zoom, pan and twist to rotate.
  • Kinetic scrolling.
  • The back button closes dialogs.
• Adaptive layout: the desktop layout on tablets, and a compact layout on phones (full-screen settings, vertical gizmo column, compact bars).
• The system file picker (Storage Access Framework) for opening models, the system WebView for Home and the setup wizard, and the light/dark theme from the system.

Known limitations

• No Bambu Lab cloud or network plugin (it is a closed-source desktop binary), and no printer camera yet.
• Some web dialogs (printer selection) are not yet adapted to narrow phone screens.
• On emulators with a software GPU, Preview toolpaths render black.
