Multi map fragments
This example demonstrates how to use multiple map views within a single activity using fragments and the Mapbox Maps SDK for Android.
The code includes logic to create and set up four different map views with distinct styles and locations. Each map fragment is initialized with a specific style using the initFragmentStyle method, which loads the specified Style and sets the camera position using the CameraOptions generated by the generateCamera method.
This example code is part of the Maps SDK for Android Examples App, a working Android project available on GitHub. Android developers are encouraged to run the examples app locally to interact with this example in an emulator and explore other features of the Maps SDK.
See our Run the Maps SDK for Android Examples App tutorial for step-by-step instructions.
