项目构建良好. Intellisense和文档工作正常.但是当我尝试在手机上运行(调试)该应用程序时，出现此错误；

推荐答案

您应该添加以下内容

<android.support.constraint.ConstraintLayout
 xmlns:android="http://schemas.android.com/apk/res/android"
 xmlns:app="http://schemas.android.com/apk/res-auto"
 xmlns:tools="http://schemas.android.com/tools"
 android:id="@+id/PLAY_PARENT"
 android:layout_width="match_parent"
 android:layout_height="match_parent"
 android:background="@drawable/greenfelt2"
 android:padding="0dp">

compile 'com.android.support.constraint:constraint-layout:1.0.2'
