Unity Googleplay Android版升级到31，Unity闪屏之后卡死
当前海外版本有硬性要求：Target API level必须升级到31，升级之后在Android 12机型上启动游戏，Unity闪屏之后卡死，其他Android版本正常。查了一下这个问题，是因为TelephonyManager的listen函数在Android 12过期了，如果没有授权READ_PHONE_STATE权限，此函数会抛出一个SecurityException。
而Unity在启用了自带的音频系统的情况下，恰巧在启动时机会去调用这个方法以实现“在用户接电话时游戏静音”的功能，抛出的异常影响了后续的流程导致卡死。
论坛上有人遇到了类似的问题，但是表现为崩溃：

项目能升级引擎的话，可以试试这里提到的修复的版本：

如果项目不能升级引擎，也有一个解决办法：
重新写一个android的启动类， 将这个问题绕过去
