Run StreetViewUtils from Java

[ryust]

I cannot figure out how to access the StreetViewUtils class from Java so I can run the fetchStreetViewData method to determine if a StreetView panorama exits. It shouldn't be this hard to use StreetViewUtils in Java since everything else in the maps utils library is available to Java.

Hi @ryust. fetchStreetViewData is a suspend function wrapped in a coroutine, so it is not directly callable from Java. The two common workarounds are to create a Kotlin helper that wraps the suspend function in a CompletableFuture or another Java-friendly async type, or to call it from Java using a Continuation manually, though the latter is cumbersome. Using the helper approach, you can expose a @JvmStatic method that Java can call safely, and it will execute the coroutine under the hood and return the result asynchronously.

Yeah, given that I'm a Kotlin novice, that goes way over my head. The point of the issue is that all other methods in the utils library are directly accessible to Java. Why make a valuable one like the StreetViewUtils a Kotlin-only class? Doesn't make sense to me. On Sep 9, 2025 3:24 AM, Enrique López-Mañas ***@***.***> wrote:kikoso left a comment (googlemaps/android-maps-utils#1590) Hi @ryust. fetchStreetViewData is a suspend function wrapped in a coroutine, so it is not directly callable from Java.

@ryust See #1595

This adds a Java helper (demo/src/main/java/com/google/maps/android/utils/demo/StreetViewHelper.kt) and demo activity (demo/src/main/java/com/google/maps/android/utils/demo/StreetViewDemoActivityJava.java)
