【参考方案1】：

我认为问题出在else 条件下

resultIntent = new Intent(this, NavigationActivity.class);
taskStackBuilder.addParentStack(NavigationActivity.class);
taskStackBuilder.addNextIntentWithParentStack(resultIntent);

您正在设置Parent 并在通知点击时打开活动相同。所以它不遵循TaskStackBuilder 的后栈架构。

您能否纠正父母并尝试一下希望这会奏效。

@ForamShah 我已经更新了答案，你也可以检查一下。

不，仍然无法正常工作。当我在 androidx 中迁移整个项目并更新 Dependencies 版本并使用 FirebaseInstanceIDService 的 FirebaseMessagingService 实例时，会引发此问题。因为 handleIntent lmethod 不在新版本中
