Kotlin启动应用程序崩溃

Question

我的应用程序是使用Kotlin构建的，这是我的build.gradle文件：

compile "org.jetbrains.kotlin:kotlin-stdlib:$kotlin_version"

并且我的工作区的build.gradle文件：

ext.kotlin_version = '1.1.3-2'
ext.kotlin_plugin_version = '1.1.1'
dependencies {
    classpath "io.realm:realm-gradle-plugin:3.4.0"
    classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_plugin_version"
}

在我的项目中，我已经使用了带有jack的Java8，所以gradle-plugin版本只能为1.1.1。但是当我启动应用程序时，它会随机崩溃。以下是日志记录：

 private var mPagerAdapter: MainFragmentAdapter? = null 

覆盖

fun initData() { mPagerAdapter = MainFragmentAdapter(supportFragmentManager, this) }

在 mPageAdapter 的 init 中发生了崩溃，在此提供 MainFragmentPagerAdapter 构造函数如下：

class MainFragmentAdapter : FragmentPagerAdapter { private val mContext:     Context constructor(fm: FragmentManager, context: Context) : super(fm) { mContext = context }

有人可以帮我吗？非常感谢！

请问您能否发布MainActivity.kt的代码，以便我们更好地了解问题。 - pRaNaY

没问题，这是MainActivity.kt的主要代码：private var mPagerAdapter: MainFragmentAdapter? = null override fun initData() { mPagerAdapter = MainFragmentAdapter(supportFragmentManager, this) }崩溃发生在mPageAdapter的init中，MainFragmentPagerAdapter的构造函数如下：class MainFragmentAdapter : FragmentPagerAdapter { private val mContext: Context constructor(fm: FragmentManager, context: Context) : super(fm) { mContext = context } - Brand Lee

尝试添加此依赖项：compile "org.jetbrains.kotlin:kotlin-reflect:$kotlin_version"。 - Aran Moncusi Ramirez

感激不尽，但它并没有如预期的那样工作...... - Brand Lee

Answer 1

以下是我添加为应用级依赖项后解决问题的内容：

implementation "org.jetbrains.kotlin:kotlin-stdlib-jre8:$kotlin_version"

---编辑---

现在已经被以下内容取代：

implementation "org.jetbrains.kotlin:kotlin-stdlib:$kotlin_version"

- Edmund Johnson

$kotlin_version 应该像 1.2.50 一样。 - Shangwu

Answer 2

在你的应用 gradle 文件中添加下面两行代码并同步你的项目。

apply plugin: 'kotlin-android'
apply plugin: "kotlin-android-extensions"

在你的Android Studio中配置Kotlin插件可能会出现问题。如果你仍然遇到同样的问题，请参考下面的链接，它可能会有帮助。

我尝试过了，但它不起作用，无论如何还是谢谢，但我在我的应用程序中使用了multi dex，我不知道multidex是否会导致这个问题？ - Brand Lee
