First, let's break down the nomenclature. Bus Simulator Indonesia (BUSSID) is developed by Maleo. Version numbers (like 3.7.1) indicate specific updates, bug fixes, and feature releases. While the official Google Play Store version might be higher or lower depending on the current release cycle, version 3.7.1 holds a special place in the community for its stability and specific mod compatibility.
The term "Obb" refers to the OBB file (Opaque Binary Blob), which contains the game’s assets—graphics, textures, maps, bus models, and sounds. While the APK (Android Package Kit) is the application itself, the Obb file is the data that makes the game look and sound impressive. You cannot run Bus Simulator Indonesia 3.7.1 properly without the matching Obb file.
This is the #1 symptom of a missing or incorrect Obb file. Double-check the file path. It must be Android/obb/com.maleo.bussimulatorid/ – not Android/data/, not Android/obb/com.maleo.bussimulatorid/dex/.
This error occurs when the APK you are using is a cracked or unsigned version, but the Obb is from the official source. To fix this, you need a matching "modded" Obb or a specific "license removed" APK. Alternatively, use the official Play Store base.
