为什么我的Android Studio应用程序无法在Android设备上运行？

Question

我已经在Android Studio 3.0.1中构建了Connect 3游戏，但是当我尝试在Samsung Android设备上运行它时，它无法运行并显示消息Unfortunately, Connect 3 Game has stopped.

Android Studio中的Logcat窗口显示很多消息，例如；

java.lang.RuntimeException: Unable to start activity ComponentInfo{com.example.stephenlearmonth.connect3game/com.example.stephenlearmonth.connect3game.MainActivity}: android.view.InflateException: Binary XML file line #0: Error inflating class android.widget.GridLayout

我已尝试在import android.widget.GridLayout;文件中将android.support.v7.widget.GridLayout;替换为MainActivity.java，但收到错误消息Cannot resolve symbol 'GridLayout'.

我已将我的minSdkVersion文件中的gradle.build设置为19。

MainActivity.java的启动

package com.example.stephenlearmonth.connect3game;

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.widget.Button;
import android.support.v7.widget.GridLayout;
import android.widget.ImageView;
import android.widget.TextView;
import android.widget.Toast;

build.gradle

apply plugin: 'com.android.application'

android {
    compileSdkVersion 26
    defaultConfig {
        applicationId "com.example.stephenlearmonth.connect3game"

Android手机显示消息Unfortunately, Connect 3 Game has stopped.
