Introduction

As a developer, encountering a rare crash in the Animator can be a frustrating experience. The crash is characterized by a java.lang.NullPointerException with a message indicating an attempt to invoke a virtual method on a null object reference. In this article, we will delve into the details of this crash, explore the possible causes, and provide steps to reproduce and resolve the issue.

Understanding the Crash

The crash occurs in the PropertyValuesHolder class, specifically in the setObjectValues method. This method is responsible for setting the object values for a property animation. However, in this case, the PropertyValuesHolder object is null, causing the crash.

Analyzing the Stacktrace

The stacktrace provides valuable information about the sequence of method calls leading up to the crash. We can see that the crash occurs in the MapboxAnimator class, specifically in the init method. The init method is called by the MapboxLatLngAnimator class, which is responsible for animating the location on the map.

Possible Causes

Based on the stacktrace and the code analysis, there are several possible causes for this crash:

Null Pointer Exception: The PropertyValuesHolder object is null, causing the crash. This could be due to a null pointer exception in the MapboxAnimator class.
Animation Configuration: The animation configuration might be incorrect, leading to a null PropertyValuesHolder object.
Mapbox SDK Version: The Mapbox SDK version might be outdated, causing compatibility issues with the Animator.

Steps to Reproduce

Reproducing this crash is extremely difficult, as it requires a specific combination of factors. However, here are some steps that might help:

Use an Outdated Mapbox SDK Version: Try using an outdated version of the Mapbox SDK to see if the crash occurs.
Configure the Animation Incorrectly: Try configuring the animation incorrectly to see if the crash occurs.
Use a Null Pointer Exception: Try introducing a null pointer exception in the MapboxAnimator class to see if the crash occurs.
