Question

我已经构建了包含2个活动的webview应用程序：webview和adMob。两者都很好地合作。唯一的问题是，当用户按广告时，它会在应用的webview中加载而不是浏览器。但这些链接对于Google Play来说意味着什么，所以当用户按广告时会出现错误：“ERR_UNKNONWN_URL_SCHEME”。广告时如何在浏览器中打开它？

有人可以告诉我解决问题的方法。这很紧急！以下是AdMobActivity.java，MainActivity.java和main_activity.xml

AdMobActivity.java

package com.example.www.probe;

import android.app.Activity;
import android.os.Bundle;

import com.google.android.gms.ads.AdRequest;
import com.google.android.gms.ads.AdView;



public class AdMobActivity extends Activity {
    @Override
    public void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        AdView adView = (AdView) findViewById(R.id.adView);
        AdRequest adRequest = new AdRequest.Builder()
                .setRequestAgent("android_studio:ad_template").build();
        adView.loadAd(adRequest);

    }

}

ActivityMain.java

package com.example.www.probe;
import com.google.android.gms.ads.AdRequest;
import com.google.android.gms.ads.AdView;
import android.app.Activity;
import android.os.Bundle;
import android.view.KeyEvent;
import android.webkit.WebView;
import android.webkit.WebViewClient;
import android.widget.Toast;

public class MainActivity extends Activity {
    private WebView mWebview ;
    @Override
    public void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        mWebview = (WebView)findViewById(R.id.webView);
        mWebview.getSettings().setJavaScriptEnabled(true);
        final Activity activity = this;

        mWebview.setWebViewClient(new WebViewClient() {
            public void onReceivedError(WebView view, int errorCode, String
description, String failingUrl) {

            }
        });
        mWebview .loadUrl("https://example.com");
    }
    @Override
    public boolean onKeyDown(int keyCode, KeyEvent event) {
        if(event.getAction() == KeyEvent.ACTION_DOWN){
            switch(keyCode)
            {
                case KeyEvent.KEYCODE_BACK:
                    if(mWebview.canGoBack() == true){
                        mWebview.goBack();
                    }else{
                        finish();
                    }
                    return true;
            }
        }
        return super.onKeyDown(keyCode, event);
    }
}

activity_main.xml中

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:ads="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="com.example.www.probe.MainActivity">


    <WebView
        android:id="@+id/webView"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_alignParentBottom="true"
        android:layout_alignParentRight="true"
        android:layout_alignParentEnd="true" />

    <com.google.android.gms.ads.AdView
        android:id="@+id/adView"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        ads:adSize="BANNER"
        ads:adUnitId="@string/banner_ad_unit_id"
        android:layout_alignParentBottom="true"
        android:layout_centerHorizontal="true" />

</RelativeLayout>

注意：在字符串文件中只有app name和ad_unit_id。

按下时，广告在应用程序的WebView中打开，而不是默认浏览器
