Hi I am trying MapBox for navigation and getting crash like this

These are the dependencies that I am using now
// MAP BOX
implementation 'com.mapbox.mapboxsdk:mapbox-android-sdk:7.0.1'
implementation 'com.mapbox.mapboxsdk:mapbox-android-navigation-ui:0.27.0'
This is where I get the crash
@Override
public void onMapReady(@NonNull MapboxMap mapboxMap) {
mMapboxMap = mapboxMap;
mapboxMap.setStyle(new Style.Builder().fromUrl(getString(R.string.navigation_guidance)), new Style.OnStyleLoaded() {
@Override
public void onStyleLoaded(@NonNull Style style) {
// enableLocationComponent();
if (style.isFullyLoaded()) {
navigationMap = new NavigationMapboxMap(mapView, mMapboxMap);
//
// // For Location updates
// initializeLocationEngine();
//
// // For navigation logic / processing
// initializeNavigation(mMapboxMap);
navigationMap.updateCameraTrackingMode(NavigationCamera.NAVIGATION_TRACKING_MODE_NONE);
}
}
});
}
This line is causing the issue
navigationMap = new NavigationMapboxMap(mapView, mMapboxMap);
I checked this link https://github.com/mapbox/mapbox-gl-native/wiki/Android-6.x-to-7.x-migration-guide
and found something like this
In order to avoid java.lang.NullPointerException: Attempt to invoke virtual method 'boolean com.mapbox.mapboxsdk.maps.Style.isFullyLoaded()' on a null object reference, the provided style parameter in the LocationComponent#activate method has to be @NonNull and fully loaded. The best way is to pass the style provided in the OnStyleLoaded callback.
But still no luck.
I was facing the same issue and tried all the solutions. I updated to latest mapbox sdk 8.4.0, and followed the ComponentNavigationActivity#onMapReady, but still no luck.
Then I found that we need to put:
<item name="navigationViewLocationLayerStyle">@style/NavigationLocationLayerStyle</item>
inside the custom instructions view style and apply it inside onCreate()
like this:
setTheme(R.style.customInstructionView);
This solved the issue. I hope it helps!
https://github.com/mapbox/mapbox-navigation-android/issues/1692 is moving to fix this by providing a default if a valid style is not found. In the meantime, you can add this snippet to your style.xml
to fix:
<item name="navigationViewLocationLayerStyle">@style/NavigationLocationLayerStyle</item>
