我将我的第一个科特林代码（一个新的活动）到一个既定的Android应用程序。 采用Android 2.3.3工作室，摇篮3.3。 我能够构建和运行应用程序，但在推出新的科特林活动点，与一类的应用程序崩溃未发现异常。 分析APK表示科特林类尚未列入DEX（和其多DEX，已签两DEX文件）。

和活动，这是非常简单的：
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);
}
