使用WebView开发应用程序：
在布局文件中：
<WebView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/webview"
android:layout_width="match_parent"
android:layout_height="match_parent"
/>
在代码中：
mVideo =（WebView）findViewById（R.id.webview）; mVideo.loadUrl（mDeviceHost +“：8080 / stream / webrtc”）;
但是当我在设备上运行时：
java.lang.RuntimeException: Unable to start activity ComponentInfo{tprlab.com.pitanq/com.tprlab.pitanq.DashboardActivity}: android.view.InflateException: Binary XML file line #0: Binary XML file line #0: Error inflating class android.webkit.WebView

有什么办法解决这个问题吗？
PS。设备上的Android版本：7.0 NRD90M（SDK版本24） 构建选项：最小SDK版本-24 目标-26。 （是钥匙吗？）
