Android低版本传递Firebase Timestamp遇类未找到错误及解决尝试

我尝试使用intent.putExtra("timeStamp", timeStamp)将com.google.firebase.Timestamp对象传递到另一个Activity，但在部分Android旧版本中触发以下错误：

我尝试了多种方案但均未解决，部分方案甚至导致全版本报错或Timestamp功能失效，具体尝试如下：

• 尝试1：
  Activity 1：

  intent.putExtra("timeStamp", timeStamp)
  

  Activity 2：

  val timeStamp = if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.TIRAMISU) {
                  intent.getParcelableExtra("timeStamp", Timestamp::class.java)
              } else {
                  intent.getParcelableExtra<Timestamp>("timeStamp")
              }
  

• 尝试2：
  Activity 1：

  intent.putExtra("timeStamp", timeStamp)
  

  Activity 2：

  intent.setExtrasClassLoader(Timestamp::class.java.classLoader)
  val timeStamp = if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.TIRAMISU) {
                  intent.getParcelableExtra("timeStamp", Timestamp::class.java)
              } else {
                  intent.getParcelableExtra<Timestamp>("timeStamp")
              }
  

• 尝试3：
  Activity 1：

  intent.setExtrasClassLoader(Timestamp::class.java.classLoader)
  intent.putExtra("timeStamp", timeStamp)
  

  Activity 2：

  val timeStamp = if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.TIRAMISU) {
                  intent.getParcelableExtra("timeStamp", Timestamp::class.java)
              } else {
                  intent.getParcelableExtra<Timestamp>("timeStamp")
              }
  

• 尝试4（改用Long类型转换）：
  Activity 1：

  intent.putExtra("timeStampLong", claim.sentTime.seconds)
  

  Activity 2：

  val timeStampLong = intent.getLongExtra("timeStampLong", -1L)
  val timeStamp = Timestamp(Date(timeStampLong))
  

  该方案起初看似可行，但转换后的Timestamp在后续使用时无响应（其他位置类似转换可正常工作）。
