I have a view and view the site has malito code to send email. When I open the link opens in an error. I want that when I open the link opens Gmail app or another email application. Thanks to all helpers.
public class teacher extends Activity implements OnClickListener {
WebView webView;
final Activity activity = this;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
this.getWindow().requestFeature(Window.FEATURE_PROGRESS);
setContentView(R.layout.teacher);
webView = (WebView) findViewById(R.id.webView145);
webView.getSettings().setJavaScriptEnabled(true); webView.loadUrl("https://dl.dropboxusercontent.com/u/233211/%D7%A8%D7%A9%D7%99%D7%95%D7%9F/iWebKit%20demo/ther.html");
webView.setWebChromeClient(new WebChromeClient() {
public void onProgressChanged(WebView view, int progress) {
activity.setTitle("Loading...");
activity.setProgress(progress * 100);
if (progress == 100)
activity.setTitle(R.string.app_name);
} });
webView.setWebViewClient(new WebViewClient() {
@Override
public void onReceivedError(WebView view, int errorCode,
String description, String failingUrl) {
// Handle the error
}
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true; } });}
public void onBackPressed() {
if (webView.canGoBack()) {
webView.goBack();
} else {
Intent B = new Intent(this, MainActivity.class);
startActivity(B);
}}
@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
if (event.getAction() == KeyEvent.ACTION_DOWN) {
switch (keyCode) {
case KeyEvent.KEYCODE_BACK:
if (webView.canGoBack() == true) {
webView.goBack();
} else {
finish();
}return true;} }
return super.onKeyDown(keyCode, event);
}
@Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
}}
You have to create a subclass of WebViewClient and override mailto URL loading. Example:
public class MyWebViewClient extends WebViewClient {
private final WeakReference<Activity> mActivityRef;
public MyWebViewClient(Activity activity) {
mActivityRef = new WeakReference<Activity>(activity);
}
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
if (url.startsWith("mailto:")) {
final Activity activity = mActivityRef.get();
if (activity != null) {
MailTo mt = MailTo.parse(url);
Intent i = newEmailIntent(activity, mt.getTo(), mt.getSubject(), mt.getBody(), mt.getCc());
activity.startActivity(i);
view.reload();
return true;
}
} else {
view.loadUrl(url);
}
return true;
}
private Intent newEmailIntent(Context context, String address, String subject, String body, String cc) {
Intent intent = new Intent(Intent.ACTION_SEND);
intent.putExtra(Intent.EXTRA_EMAIL, new String[] { address });
intent.putExtra(Intent.EXTRA_TEXT, body);
intent.putExtra(Intent.EXTRA_SUBJECT, subject);
intent.putExtra(Intent.EXTRA_CC, cc);
intent.setType("message/rfc822");
return intent;
}
}
Then you have to set this custom WebViewClient to your WabView:
webView.setWebViewClient(new MyWebViewClient(activity);
You should update your's WebViewClient with the following:
@SuppressWarnings("deprecation")
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
proceedUrl(view, Uri.parse(url))
return true;
}
@TargetApi(Build.VERSION_CODES.N)
@Override
public boolean shouldOverrideUrlLoading(WebView view, WebResourceRequest request) {
proceedUrl(view, request.getUrl());
return true;
}
private void proceedUrl(View view, Uri uri){
if (uri.toString().startsWith("mailto:")) {
startActivity(new Intent(Intent.ACTION_SENDTO, uri));
} else if (uri.toString().startsWith("tel:")) {
startActivity(new Intent(Intent.ACTION_DIAL, uri));
} else {
view.loadUrl(uri.toString());
}
}
Note : - After Android Nougat shouldOverrideUrlLoading
is Deprecated
You need to use shouldOverrideUrlLoading
along with shouldOverrideUrlLoading
for better support.
Also, you might want to check if URL have mailto:
or tel:
, which are used in HTML5 to trigger mail client and phone dial respectively.
A complete solution will look like this now
@SuppressWarnings("deprecation")
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
if (url.startsWith("mailto:")) {
//Handle mail Urls
startActivity(new Intent(Intent.ACTION_SENDTO, Uri.parse(url)));
} else if (url.startsWith("tel:")) {
//Handle telephony Urls
startActivity(new Intent(Intent.ACTION_DIAL, Uri.parse(url)));
} else {
view.loadUrl(url);
}
return true;
}
@TargetApi(Build.VERSION_CODES.N)
@Override
public boolean shouldOverrideUrlLoading(WebView view, WebResourceRequest request) {
final Uri uri = request.getUrl();
if (uri.toString().startsWith("mailto:")) {
//Handle mail Urls
startActivity(new Intent(Intent.ACTION_SENDTO, uri));
} else if (uri.toString().startsWith("tel:")) {
//Handle telephony Urls
startActivity(new Intent(Intent.ACTION_DIAL, uri));
} else {
//Handle Web Urls
view.loadUrl(uri.toString());
}
return true;
}
