Symbol listener
Not compatible with the Maps SDK v10
This plugin is not compatible with the Maps SDK v10 or higher. The Maps SDK v10 and higher comes with annotation functionality built in. See the Markers and annotations guide.
This example uses the Annotation plugin to add a symbol to a map and add listeners to the symbol.
You must install the plugin before running the application.
Note
This example is a part of the Mapbox Android Demo app. You can find the values for all referenced resources in the res directory. For example, see res/values/activity_strings.xml for R.string.* references used in this example. The dependencies can be found here.The examples use View binding.See setup documention if necessary.
