英文:
Android flow for Simple API call
问题
我进行简单的API调用,返回成功或错误。我使用Livedata或SingleLiveEvent来进行API调用并根据结果更新UI。我可以用Flow替代它们吗?
就我理解,Flow更适用于处理数据流并在数据发生变化时更新UI。例如,数据库中的数据更改。
请帮助我更好地理解这一点。
英文:
I make simple api calls that return success or error. I use Livedata or SingleLiveEvent for making an api call and updating the UI based on the result. Can I replace them with flow?
As I understand, flow is more meant for processing stream of data and update the Ui when there is change in the data. For example change of data in database.
Please help me understand this better

LiveData是Android Jetpack的一部分,与任何可观察的数据持有类一样,但具有专为Android构建的生命周期感知功能,而Flow是Kotlin的一部分,建立在协程之上,并不是专为Android构建的。
如果您想使用Flow,可以用MutableStateFlow替代LiveData(MutableLiveData用MutableStateFlow替代)。为了更好的迁移,

英文:
LiveData is part of Android jetpack, just like any observable data holder class but with lifecycle-awareness built specifically for android whereas flow is part of kotlin and are built on top of coroutines and aren't built specifically for Android.
If you want to use flow, you can replace livedata with stateflow (mutableLivedata with mutableStateFlow). For better migration
