Webview link opens in external browser

Question

I am a beginner in making android applications. I followed THIS tutorial on how to make a webview and I ran the app on my Galaxy Note 2 without any errors, but the link written in the code wants to open in a external browser when the app is opened. I want the page to be visible inside the web view in the application. How do i proceed to do this?

MainActivity.java

    WebView browser;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    // find the WebView by name in the main.xml of step 2
    browser=(WebView)findViewById(R.id.wvwMain);

    // Enable javascript
    browser.getSettings().setJavaScriptEnabled(true);

    // load a webpage
    browser.loadUrl("http://www.google.com/");

}

Answer 1

Add this inside your oncreate():

browser.setWebViewClient(new WebViewClient()); //open urls inside browser

Answer 2

To help you better understand, I'm leaving my simple browser app code here for you.

Here SimpleBrowser is the MainActivity.

public class SimpleBrowser extends Activity implements OnClickListener {
WebView ourBrowser;
EditText url;
Button go, go_Back, go_Forward, refresh, clr_History;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.browser_webview);

    ourBrowser = (WebView) findViewById(R.id.WVBrowser);
    /* WebView Settings pretty important */
    ourBrowser.getSettings().setJavaScriptEnabled(true);
    ourBrowser.getSettings().setLoadWithOverviewMode(true);
    ourBrowser.getSettings().setUseWideViewPort(true);

    ourBrowser.setWebViewClient(new ourViewClient());
    try {
        ourBrowser.loadUrl("http://www.mybringback.com");
    } catch (Exception e) {
        e.printStackTrace();
    }

    go = (Button) findViewById(R.id.btn_Go);
    go_Back = (Button) findViewById(R.id.btn_GoBack);
    go_Forward = (Button) findViewById(R.id.btn_GoForward);
    refresh = (Button) findViewById(R.id.btn_RefreshPage);
    clr_History = (Button) findViewById(R.id.btn_ClrHistory);
    url = (EditText) findViewById(R.id.eT_webbrowser);

    go.setOnClickListener(this);
    go_Back.setOnClickListener(this);
    go_Forward.setOnClickListener(this);
    refresh.setOnClickListener(this);
    clr_History.setOnClickListener(this);

}

@Override
public void onClick(View view) {
    switch (view.getId()) {
    case R.id.btn_Go:
        String newWebaddress = url.getText().toString();
        ourBrowser.loadUrl(newWebaddress);

        /* Hiding the keyboard after the EditText data */
        InputMethodManager ipmm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
        ipmm.hideSoftInputFromWindow(url.getWindowToken(), 0);
        break;

    case R.id.btn_GoBack:
        if (ourBrowser.canGoBack()) {
            ourBrowser.goBack();
        }
        break;

    case R.id.btn_GoForward:
        if (ourBrowser.canGoForward()) {
            ourBrowser.goForward();
        }
        break;

    case R.id.btn_RefreshPage:
        ourBrowser.reload();
        break;

    case R.id.btn_ClrHistory:
        ourBrowser.clearHistory();
        break;
    }
}

}
Then have another Java file with name : ourViewClient.java and it should contain the below code:

public class ourViewClient extends WebViewClient {

    @Override
    public boolean shouldOverrideUrlLoading(WebView view, String url) {
        view.loadUrl(url);

        return true; // as mentioned in below notes, for your case., you do 'return false'
    }

}

Android Manifest file: Ensure to have <uses-permission android:name="android.permission.INTERNET" /> declared. browser_webview.xml file

You simply solve this problem with this:

        myWebView.setWebViewClient(new HelloWebViewClient());
...
private class HelloWebViewClient extends WebViewClient {
    @Override
    public boolean shouldOverrideUrlLoading(WebView view, String url) {
        if (Uri.parse(url).getHost().equals("yoursite.com")) {
            // This is my web site, so do not override; let my WebView load the page
            return false;
        }
        // Otherwise, the link is not for a page on my site, so launch another Activity that handles URLs
        Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
        startActivity(intent);
        return true;
    }
}
