APK不包含Kotlin活动 [英] Kotlin Activity not included in APK
问题描述
将我的第一个Kotlin代码(一项新活动)引入已建立的Android应用程序中.使用Android Studio 2.3.3，Gradle 3.3.我能够构建和运行该应用程序，但是在启动新的Kotlin活动时，应用程序崩溃，并发现一个类未发现异常.对APK进行分析后，发现dex中未包含Kotlin类(及其多dex，已经检查了两个dex文件).
Am introducing my first Kotlin code (a new activity) into an established Android app. Using Android Studio 2.3.3, Gradle 3.3. I am able to build and run the app but at the point of launching the new Kotlin activity, app crashes with a class not found exception. Analyzing the APK indicates the Kotlin class has not been included in the dex (and its multi-dex, have checked both dex files).

和活动，这很简单:
class HyperFlashActivity : AppCompatActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(hyperflash_activity_layout)
}
}
和启动代码:
public static void launchHyperflashActivity(Activity launchingActivity) {
Intent intent = new Intent(launchingActivity, HyperFlashActivity.class);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
launchingActivity.startActivity(intent);
launchingActivity.overridePendingTransition(R.anim.slide_in_right, R.anim.slide_out_left);
}
推荐答案
我曾经遇到过相同的问题 1 ，基本上，解决方法是代替Android Studio 2.x下载 Android Studio 3.0 Beta .即使使用2.x版本突出显示代码时，这也应该可以解决您的问题.
I once had the same issue1 and basically the fix was to instead of Android Studio 2.x download the Android Studio 3.0 Beta. This should fix your problem even if the code highlighting does work when using the 2.x version.
当您查看新功能"标签时，您会看到它提供了对Kotlin语言的支持，而种类则表明它以前是缺少的(我认为在这种情况下，它只是内置于Android Studio中，并专门针对Android Studio的要求进行了增强(例如，包括该类)到dex文件)).
When you look at the New Features tab you can see that it features support for Kotlin language which kind of suggests it was lacking before (I think in this case it was just built into Android Studio and enhanced specifically for Android Studio's requirements (such as including the class to the dex file)).
1 :除了multidex以外，因为我不需要它
1: with the exception of multidex as I didn't need it
