我的代码在我正常运行时工作正常，但是当我运行此单元测试时，此错误会打印在控制台中。我在这个单元测试中做错了什么？

测试运行失败：由于“进程崩溃”，检测运行失败。

看来您的代码正在回收位图，然后立即尝试再次使用它：

    gameEngine.DrawAnimationObject(canvas, animationbmp, ImagesPos.x, ImagesPos.y, SheetSize, CurrentSprite, rot);
    //////////////////////////////////////////////
    animationbmp.recycle(); //Offending line here/
    //////////////////////////////////////////////
    gameEngine.DrawAnimationObject(canvas, animationbmp, ImagesPos.x, ImagesPos.y, SheetSize, CurrentSprite, rot);

您不应该在回收后使用位图。您需要再次重新创建该位图对象，因为内存现在无效。

您调用的 C++ 库因尝试取消引用内存地址 0x00...28 而崩溃。看起来像 libskia.so，它是 android 处理图形子系统的一部分。该内存地址意味着它可能正在查看数组中的第 N 个项目，但该数组为空。我会寻找一个传递给绘图调用的空指针，或者对 libskia 错误进行一些严肃的谷歌搜索。恐怕我无能为力，但这是一个开始。
