• Kotlin: How to return a variable from within an asynchronous lambda?

  I'm using fuel http to make a simple GET request. Here's my code:

  fun fetchTweets(): List<Tweet> {
  
      endpoint.httpGet(listOf("user" to "me", "limit" to 20))
          .responseObject(Tweet.Deserializer()) { _, _, result ->
              result.get().forEach { Log.i("TWEET", it.text) }
              val tweets = c.get().toList() //I want to return this
          }
  }
  

  If I do return tweets just below val tweets, I get an error: return is not allowed here.

  The makes sense to me. But the question still remains, how do I write a function that returns the variable created within the lambda? In this case, I want to return tweets
• SQLite database as IntentService, caching database state?

  The documentation for Android's SQLite interfaces mention that database accesses should be performed from an IntentService as they are potentially long-running operations, so the GUI thread should not block on them.

  The IntentService is shut down as soon as no further Intents are queued for it, which would happen basically after every request, so the database handles are built up and destroyed for each query as well, which seems wasteful.

  • Is there a way to keep an IntentService around longer, or somehow otherwise avoid a race between the GUI thread posting more Intents and the service answering them?

  • Should I just make my query Intents contain a list of queries that should all be performed, or would that cause other problems with message sizes?
• How to observe member variables of a class in MutableLiveData?

  I am trying to observe fields of my class without exposing it. So far, I've tried this:

  open class TaskItemViewModel(private val navigator: ITaskNavigator) : ViewModel() {
  
      private val taskItem: MutableLiveData<TaskItem> = MutableLiveData()
  
      val title: LiveData<String?> = Transformations.map(taskItem) { it.title }
  
      val content: LiveData<String?> = Transformations.map(taskItem) { it.content }
  
      var showCheck: LiveData<Boolean> = Transformations.map(taskItem) { it.isCompleted }
  
      fun setModel(model: TaskItem) {
          this.taskItem.value = model
      }
  }
  

  If I call setModel before inflating the view, everything works fine. However, after the view is inflated, the view is not updated even if taskItem 's value is updated.

  I will instantiate a new TaskItemViewModel for every viewHolder in my RecyclerView. So the setModel function is called in an adapter. I have tried adding getter and setters for my ViewModel fields but they are still not being updated. What are the ways to achieve this?

  For this viewmodel, I want to use ViewModel rather than BaseObservable. Therefore, please give your answers according to this.
• How can I show facebook page posts to android app

  I want to show facebook page posts to my android app with page name, image, time & date of post, description and likes. I created project on facebook developer and tried using:

  I have a problem with google api in my chat bot of fb messenger. When I open the map on the chat, messenger open the "internal" browser windows with the map of google with all the markers...So... I have not problem on desktop and on android devices but on Ios if I try to click on one of these Markers on the map it doesn't show me the "box info", If I open that on safari or chrome ecc It's all ok, but I don't like that. I whant that it works also with the "window broswer of messenger" becouse no one open the links to external browser... What could I do? I tried with:

• Firebase Hosting - how to creating a publicly accessible folder?

  I am using Firebase Hosting to host my React application (I'm using Webpack). I need to create a publicly accessible folder on my website and upload a file to it, like this: https://www.example.com/.well-known/assetlinks.json. Locally, I've created the top level .well-known folder with assetlinks.json in it and can now access the file at localhost:9562/.well-known/assetlinks.json. I then deployed my project to Firebase, but https://www.example.com/.well-known/assetlinks.json displays a blank page.

• Implement distributed counter on Firebase

  I am trying to implement a three shard distributed counter at /counters/{i}.

  Initially, I want to check if the document/collection exists, if it doesn't it needs to be recreated, with userCount set to 0.

  If it does exist, then the above step is skipped, and userCount is incremented by one.

  How do I go about doing this? This is my code so far:

    incrementUserCount() {
  
      // First check to see if user exists
  
      for (let i = 0; i < environment.numberOfShards; i++) {
        const newShardReference = this.afs.firestore.collection('counters').doc(i.toString());
        this.afs.firestore.batch().set(newShardReference, { userCount: 0 });
      }
      this.afs.firestore.batch().commit();
  
      // Steps to increment user count
  
      // const shardId = Math.floor(Math.random() * environment.numberOfShards).toString();
      // const shardReference = this.afs.firestore.collection('counters').doc(shardId);
  
      // return this.afs.firestore.runTransaction(t => {
      //   return t.get(shardReference).then(doc => {
      //     const newCount = doc.data().count + 1;
      //     t.update(shardReference, { count: newCount });
      //   });
      // });
    }

• Check If image exist before uploading in Firebase Storage

  I am trying to upload data in firebase, that require Image to be stored first if image exist.

  One way is to check if image exist and execute the code and if not then execute the data part directly

  However, This can bring duplicacy of code. Can someone suggest a better way to do it and handle if image is null?

  let fileT = this.$refs.thumbnail.files[0];

• why do i get Error 'GET firebase url net::ERR_SPDY_PROTOCOL_ERROR' firebase storage

  I am having very confusing results with this code that is supposed to download a file from firebase storage to computer or device

  save.addEventListener('click',function(){
              var url=save.getAttribute('url');
              console.log(url);
              var xhr = new XMLHttpRequest();
                xhr.responseType = 'blob';
                xhr.onload = function(event) {
                  var blob = xhr.response;
                };
                xhr.open('GET', url);
                xhr.send();
          });
  

  first when i click the button it logs the url to console but nothing happens. If i click the link from the console it opens in a new tab and downloads the file. How can i enhance this behavior to click and start download like normal browsers do Still, after some time, on clicking the same link I get an error

  GET https://firebasestorage.googleapis.com/v0/b/hrty.appspot.com/o/User%20Documents%20-%20Mitch%20Albom.mobi?alt=media&token=158af967-8832-4836-9193-05ab2cb076b9 net::ERR_SPDY_PROTOCOL_ERROR
  

  Why is this should a new url be generated for the file
