私のネイティブスクリプトアプリケーションは、最初の実行ではエラーなしで正常に実行されますが、ファイルを変更せずに保存したり、小さな変更を加えたりすると、以下の情報でアプリがクラッシュします。

contact-us.xml ファイルの内容も次のとおりです。
<Page xmlns="http://www.nativescript.org/tns.xsd" navigatingTo="onNavigatedTo">
<ScrollView>
<StackLayout>
<Label text="Contact us by submitting a message below." textWrap="true" />
<TextField hint="Enter a subject..." />
<TextView hint="Enter a Message..."/>
<Button text="Submit" tap="onTap" />
</StackLayout>
</ScrollView>
</Page>
そうではありません： ctrl + cとyでアプリを停止し、 tns run androidでアプリを再起動すると、エラーなしで正常に実行されます。
