我最近升级到 Android Studio Flamingo 和 AGP 8.0

我的生产版本启用了 minfiy 和 ShrinkResources，不允许改造进行调用。这是抛出的错误。

我在 retorfit 的 github 上发现了这个问题 - https://github.com/square/retrofit/issues/3751。并添加了新规则已在这里评论 - https://github.com/square/retrofit/issues/3751#issuecomment-1192043644

# Keep generic signature of Call, Response (R8 full mode strips signatures from …

我在选项卡布局中有 2 个片段，使用 ViewBinding 在它们之间快速切换会导致视图返回为 null。这是因为构建 FragmentXBinding 类的延迟吗？

使用示例：

chatadapter.registerAdapterDataObserver(new RecyclerView.AdapterDataObserver() {
            @Override
            public void onItemRangeInserted(int positionStart, int itemCount) {
                binding.chatRecyclerView.smoothScrollToPosition(0);
            }
        });

错误：

java.lang.NullPointerException: Attempt to read from field 'androidx.recyclerview.widget.RecyclerView com.iku.databinding.FragmentChatBinding.chatRecyclerView' on a null object reference

把最新的collect放在observe里面好不好？

viewModel.fetchUserProfileLocal(PreferencesManager(requireContext()).userName!!)
            .observe(viewLifecycleOwner) {
                if (it != null) {
                    viewLifecycleOwner.lifecycleScope.launch {
                        viewLifecycleOwner.repeatOnLifecycle(Lifecycle.State.STARTED) {
                            launch {
                                viewModel.referralDetailsResponse.collect { referralResponseState ->
                                    when (referralResponseState) {
                                        State.Empty -> {
                                        }
                                        is State.Failed -> {
                                            Timber.e("${referralResponseState.message}")
                                        }
                                        State.Loading -> {
                                            Timber.i("LOADING")
                                        }
                                        is State.Success<*> -> {
                                            // ACCESS LIVEDATA RESULT HERE??
}}}}

我确信不是，当本地数据库发生变化时，我的 API 也会被调用三次，正确的方法是什么？

我的 ViewModel 看起来像这样，我从本地 Room DB 获取用户信息，推荐详细信息响应是 API 响应

private val _referralDetailsResponse = Channel<State>(Channel.BUFFERED)
val referralDetailsResponse = _referralDetailsResponse.receiveAsFlow()

init {
        val inviteSlug: String? = savedStateHandle["inviteSlug"]
        // Fire invite link
        if (inviteSlug …

基本上就是标题。

如果我必须找到我所知道的单一领域

a.any {
    it.name == "user"
}

现在我有一个 listOf(Groups) 其中包含唯一的 ID

我想检查一下

如果 user.groups.anyItemInThisList.UNIQUEID == otheruser.groups.anyItemInThisList.UNIQUEID

我的数据看起来像这样

{
   "groups":[
      {
         "id":4
         "group":"Test Group",
         "role":"creator",
         "member_count":1,
         "userType":"local"
      }
   ]
}
