Kotlin启动应用程序崩溃

Question

我的应用程序是用kotlin构建的，这是我的build.gradle文件：

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

和我的工作区的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java8和jack了，所以gradle-plugin版本只能是1.1.1

当我启动我的应用程序时，它随机崩溃，这是日志：

 private var mPagerAdapter: MainFragmentAdapter? = null 

覆写

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

崩溃发生在mPageAdapter的初始化中，MainFragmentPagerAdapter的构造函数如下：

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

有人可以帮我很多忙吗！

Answer 1

添加以下作为应用程序级依赖项为我修复了它：

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

- - 编辑 - -

现在已被以下内容取代：

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

Answer 2

在您的应用程序 gradle 中添加以下两行并同步您的项目。

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

在您的 android studio 中配置 kotlin 插件可能会出现问题。如果您仍然遇到相同的问题，请参阅下面的链接，这可能会有所帮助。
