On a freshly initialised RN project I can't get beyond this when trying to build in Android Studio.

e: file:///D:/apps/sample/node_modules/@rnmapbox/maps/android/src/main/java/com/rnmapbox/rnmbx/utils/DownloadMapImageTask.kt:80:56 Only safe (?.) or non-null asserted (!!.) calls are allowed on a nullable receiver of type 'Bitmap?'.

To have tem local fix you can navigate to the following file and add the code same as in the following PR:

Thanks for the report. I reproduced this on a fresh RN 0.87.0 app (Kotlin 2.2.0, Gradle 9.4.1, AGP 9.2.1): CloseableStaticBitmap.underlyingBitmap is nullable in the newer Fresco that RN 0.87 ships, so line 80 no longer compiles. The addBitmapImage error on line 87 is a follow-on from that one.

#4297 fixes it by skipping the image when the bitmap is null. #4299 changes the same line with !!, which would throw if the bitmap is ever null, so I would go with #4297. Until one is merged, a patch-package patch of that one line works.

On AGP 9 you also need #4282, which replaces proguard-android.txt with proguard-android-optimize.txt (#4281).
