问题 I have an issue with FileInputStream on Android with Kotlin and Okhttp. I want to post a video file by using an API, but if this file is bigger than 128mb I have to upload it chunk by chunk. So, in my request header I have to specified the Content-Range (Something like this: Content-Range bytes 0-10485759/189305151 ) And I need to post only this part of the file, that why I'm using FileInputStream, then repeat for each chunks. I'm also using FileInputStream to avoid to split the file locally

问题 I have two different projects. In the first one I use ViewModel with my activity and Room database. Everything works. Then I just created new project for different purposes and there I instantiate ViewModel absolutely the same way, but my app crashes with this error: java.lang.RuntimeException: Unable to start activity ComponentInfo{com.example/com.example.MainActivity}: java.lang.RuntimeException: Cannot create an instance of class com.example.MainViewModel at android.app.ActivityThread

问题 I am trying a very simple tentative to insert and select to/from MySql using vertx for the first time. It is funny to me that I can build and debug the application but I never get either ar.succeeded or failed. How to execute the insert and select bellow? Do I have to enclose somehow client.query and subscribe it? I am complete stuck. All examples on internet I see follow this approach. package com.mybank import io.vertx.kotlin.mysqlclient.mySQLConnectOptionsOf import io.vertx.kotlin

问题 I've just started learning android development with Kotlin. I have a recycler view that lists items. I'm trying to create onClick event for the item and then start a new intent and pass along the item id. I'm getting an error when trying to instantiate the Intent "None of the following functions can be called with the arguments supplied". I think it's because I cannot access the context of the view? override fun onBindViewHolder(holder: ViewHolder, position: Int) { holder.id = events[position

问题 I'm using IntelliJ IDEA Community 2020.2.3. My project is built around Kotlin 1.3.30 and Java 11. I've upgraded one of my dependecy to java 11 too, and after that, the IDE shows the dependency under "External Libraries", it build the app without errors, Maven build it from terminal without error, but the IDE shows unresolved references on each occurrency of the classes, functions and imports of that library. I already tried to empty the cache or deleting idea files and importing again the
