提问by Kundan Atre
回答by Shylendra Madda
Try this:
尝试这个：
- Enable Developer Options in Device (Settings-->About Phone-->Tap 7 times on build number)
- Turn on Developer options and Enable USB Debugging (in Developer Options)
Add this line in your custom Application class or in the Activity where the Web View is loaded
// if your build is in debug mode, enable inspecting of web views
if (0 != (getApplicationInfo().flags & ApplicationInfo.FLAG_DEBUGGABLE)) { WebView.setWebContentsDebuggingEnabled(true); }Open Chrome and type
chrome://inspect/#devicesand you should see your device in the Remote Target List- Click on inspect to debug it.
- 在设备中启用开发者选项（设置-->关于手机-->点击内部版本号7次）
- 打开开发人员选项并启用 USB 调试（在开发人员选项中）
在您的自定义应用程序类或加载 Web 视图的活动中添加此行
// 如果您的构建处于调试模式，则启用 Web 视图检查
if (0 != (getApplicationInfo().flags & ApplicationInfo.FLAG_DEBUGGABLE)) { WebView.setWebContentsDebuggingEnabled(true); }打开 Chrome 并输入
chrome://inspect/#devices，您应该会在远程目标列表中看到您的设备- 单击检查以对其进行调试。

This is what worked for me, override the method onCreatein MainActivity.javaand add this line in the method WebView.setWebContentsDebuggingEnabled(true).
这对我有用，覆盖方法并在方法onCreate中MainActivity.java添加这一行WebView.setWebContentsDebuggingEnabled(true)。
Here is what my code looks like:
这是我的代码的样子：
package com.myapp;
import com.facebook.react.ReactActivity;
import android.webkit.WebView;
import android.os.Bundle;
public class MainActivity extends ReactActivity {
/**
* Returns the name of the main component registered from JavaScript.
* This is used to schedule rendering of the component.
*/
@Override
protected String getMainComponentName() {
return "myapp";
}
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//added this line with necessary imports at the top.
WebView.setWebContentsDebuggingEnabled(true);
}
}
Build your code, open your app in phone and go to chrome://inspect , You would see your app listed over there. Click on inspect link.
构建您的代码，在手机中打开您的应用程序并转到 chrome://inspect ，您会看到您的应用程序在那里列出。单击检查链接。

If what you are looking for is a way to turn on WebView debugging for an app that you don'thave the source code to, this can be done but you will need to decompile and recompile the app.
如果您正在寻找一种为没有源代码的应用程序打开 WebView 调试的方法，则可以这样做，但您需要反编译并重新编译应用程序。

To debug webviews in the android app, you have to set WebView.setWebContentsDebuggingEnabled(true) in the WebviewActivity
要在 android 应用程序中调试 webviews，您必须在 WebviewActivity 中设置 WebView.setWebContentsDebuggingEnabled(true)
Open chrome://inspect/#device to debug. Use port forwarding. Hope this helps! https://developers.google.com/web/tools/chrome-devtools/remote-debugging/webviews
打开 chrome://inspect/#device 进行调试。使用端口转发。希望这可以帮助！ https://developers.google.com/web/tools/chrome-devtools/remote-debugging/webviews
