TemplateManagerPlugin

A Code On the Go (COGO) IDE plugin for managing .cgt project/file templates directly on-device — browse installed templates, install new ones from your Downloads folder, and uninstall or delete them, all from a single screen inside the IDE.

What it does

The plugin adds a TemplateManagerPlugin entry to the IDE's left sidebar (and a matching editor tab) that shows a card list of every .cgt template it can find:

• Installed templates — every .cgt registered in the IDE's template store ($IDE_HOME/templates), shown with a green Installed status. These are the templates that appear in the IDE's New Project / New File wizard.
• Available templates — every .cgt sitting in /sdcard/Download, shown with a red Not installed status, ready to be installed.

Each card shows the template's name, version, description, and source filename. A .cgt file can bundle more than one template (the IDE's own core.cgt bundles nine); when it does, the card shows a "Contains N templates" indicator, and tapping the card (or its View templates menu entry) opens a sub-screen with one card per bundled template — each with its own Details action.

Per-card actions

Each card has an overflow (⋮) menu:

Card state	Single-template	Multi-template
Installed	Uninstall, Details	Uninstall, View templates
Not installed (in Downloads)	Install, Details, Delete	Install, View templates, Delete

• Install — registers the template with the IDE and moves the file out of Downloads into the template store (it no longer appears as a Downloads entry).
• Uninstall — unregisters the template and moves it back to Downloads under its original filename, where it reappears as Not installed.
• Delete — permanently removes the .cgt from Downloads, after a confirmation dialog.
• Details — shows a single template's metadata (version, description, and any optional wizard parameters declared under parameters.optional); scrollable.
• View templates — for a multi-template .cgt, opens the per-template card sub-screen described above; each of those cards has its own Details.

Install / Uninstall / Delete always operate on the whole .cgt file, since that's the unit the IDE registers.

Building

Requires the COGO plugin-api (vendored at libs/plugin-api.jar) and the com.itsaky.androidide.plugins.build Gradle plugin.

./gradlew assemblePluginDebug     # build/plugin/templatemanagerplugin-debug.cgp
./gradlew assemblePlugin          # build/plugin/templatemanagerplugin.cgp  (release)

Prebuilt plugin

A prebuilt release .cgp is checked into the repo at prebuilt/templatemanagerplugin.cgp so you can install it without running a local Gradle build — just copy that file to the device and follow the steps below. (Rebuild from source with the commands above if you need the latest changes.)

Installing

1. Copy a .cgp to the device (e.g. into Download/) — either the prebuilt one or your own build from build/plugin/.
2. In Code On the Go, open Settings → Plugin Manager.
3. Tap the + button, pick the .cgp file, and confirm.
4. Restart the IDE when prompted.

The plugin then appears in the left sidebar.

Upgrading an already-installed copy? Code On the Go compares the .cgp's signing certificate against the installed one and refuses the install if they differ, showing "…was installed from a different build variant. Uninstall it before installing this version." Despite the wording, this is a signature mismatch — release builds here aren't signed with a stable key, so it triggers on essentially every rebuild, as well as when switching between debug and release. (Debug rebuilds on the same machine share the debug keystore, so those can be replaced in place.) When you hit it, uninstall the existing plugin first (its ⋮ menu → Uninstall), restart, then install the new .cgp.

Plugin manifest

Field	Value
plugin.id	org.appdevforall.templatemanagerplugin
plugin.main_class	org.appdevforall.templatemanagerplugin.TemplateManagerPlugin
plugin.permissions	filesystem.write
plugin.min_ide_version	1.0.0

filesystem.write is the only permission requested — it's what IdeTemplateService.registerTemplate() / unregisterTemplate() require. Reading the .cgt files themselves and moving them in/out of Downloads uses direct file access (the host app already holds MANAGE_EXTERNAL_STORAGE).
