如何处理E / JavaBinder：失败的BINDER交易导致应用程序崩溃？
我正在使用SurfaceView制作Android游戏。
我还在无限循环本身使用专用线程，其中既包含update（）方法，又包含draw（）方法。
update（）方法更新字符position（logic）和sprite，而draw（）方法绘制到画布。
专用线程同时处理update（）和draw（），因为它们需要同步。
onTouchEvent（用户点击）由主线程处理。
尽管我不能确定，但我怀疑出现此错误： E / JavaBinder：!!!绑定交易失败，因为 draw（）方法和update（）方法都调用其他方法，这些方法又调用其他方法，依此类推..导致几乎是递归的行为。
例如我的update（）方法，调用characterOne.update（）..然后调用characterOneSpells.update（），然后调用spellOne.update（），依此类推...对于draw（）来说是相同的。我怀疑这会溢出绑定缓冲区或类似的内容。.我不确定..所有这些都在无限循环中无限次发生。
请注意，我采用这种方法（方法称为调用其他方法的方法），因为在逻辑上我认为角色应该负责绘制自己，而咒语应该负责绘制自身，而不是角色负责绘制和更新咒语等。对我来说，每个对象都应负责绘制和更新自身，那就是我的推理，我可能错了，请让我知道您的想法。
现在，我是游戏制作的新手，而实际上这是我的第一款游戏，所以请放轻松，我正在尝试学习！
我的代码示例和错误日志可以在下面找到。
对为什么我得到这个 E / JavaBinder的任何见解：!!!绑定交易失败！，以及如何解决该问题，将不胜感激！也要随时提出更好的设计或方法，因为我正在尝试学习。
谢谢！
我用**重要**注释标记了代码的重要部分，使事情变得更容易。
