Open other app from webview in Android?

Question

Hi, I want to open another applications like Facebook, google play etc., while user clicks links in the webview of my application. I have given facebook.com link to the buttons. However app doesn't load by clicking that. Please help.

Answer 1

You have to add custom WebViewClient to be able to handle clicks on link buttons of WebView directly in Android Java.

webView.setWebViewClient(new CustomWebViewClient());

Override shouldOverrideUrlLoading method in class,

public boolean shouldOverrideUrlLoading(final WebView webView, final String url) {
    if (url.startsWith("<app.url or something to identify>://")) {
        final Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
        // This opens other apps
        intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_SINGLE_TOP);
        activity.startActivity(intent);
        return true;
    }  
    return false;
}

Hi,you need to use intents to open facebook ,google play etc to open them when users click on links given in webview:

Intent intent = new Intent();
intent.setClassName("com.facebook.katana","com.facebook.katana.ProxyAuth");
intent.putExtra("client_id", applicationId); // authorizes an  action, taken from facebook API
mAuthActivityCode = activityCode;
activity.startActivityForResult(intent, activityCode);

Similarly you can do this for other apps by replacing com.facebook.katana that is package name of app.
