- A native Android library project located in the project folder does not show the PluginImporter window, instead it shows a default inspector window.
- Android Library Projects can only be recognized as such, if they are stored in the following folder: Assets/Plugins/Android/
If your plugin is an Android Library Project, it needs to be placed in Assets/Plugins/Android/.
Alternatively, you can pack your library project into the binary format, as an .aar library. Aar libraries do not have this limitation and can be placed anywhere inside the Assets folder.
