Android 7.0 or upper mailto link not working in webView

My code is:
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_web_view);
ButterKnife.bind(this);
String url = getIntent().getStringExtra(EXTRA_URL);
webView.setWebChromeClient(new WebChromeClient());
webView.getSettings().setJavaScriptEnabled(true);
webView.loadUrl(url);
webView.setWebViewClient(new WebViewClient() {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
startActivity(intent);
return true;
}
});
}
When send mail link pressed, shows this error:
net::ERR_UNKNOWN_URL_SCHEME
regards!!

You load the url BEFORE you set webviewclient. Try to set the webviewclient first and invoke loadUrl() afterwards.
EDIT
#Override
public boolean shouldOverrideUrlLoading (WebView view, String url) {
Uri uri = Uri.parseUri(url);
if ("mailto".equalsIgnoreCase(uri.getScheme()) == true) {
try {
// handle mailto-urls...
Intent sendIntent = new Intent(Intent.ACTION_SENDTO);
sendIntent.setData(uri);
view.getContext().startActivity(sendIntent);
} catch (ActivityNotFoundException e) {}
return true;
}
// load everything else in webview
return false;
}

Android Assess Camera/Gallery on WebView?

Open camera for input type file in Webview not opening Android

I a newbie in android. I am creating a small app to take photo and upload it to server. I am using Webview and html form do that. In browser (chrome) camera is opening. But in webview, camera is not opened when "choose file" is clicked. Anyone know a solution? Below is the code i used....
HTML Code
<html>
<body>
<form>
<input type="file" accept="image/*;capture=camera"/>
<input type="submit"/>
</form>
</body>
</html>
Java code used in Android (eclipse)
public class MainActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
WebView myWebView = (WebView) findViewById(R.id.webview);
myWebView.setWebViewClient(new WebViewClient());
WebSettings webSettings = myWebView.getSettings();
webSettings.setJavaScriptEnabled(true);
myWebView.loadUrl("http://www.inforge.in/thejus/test.html");
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
}

try this:
webview.getSettings().setJavaScriptEnabled(true);
webview.getSettings().setPluginState(WebSettings.PluginState.ON);
webview.getSettings().setMediaPlaybackRequiresUserGesture(false);
webview.setWebChromeClient(new WebChromeClient(){
// Need to accept permissions to use the camera
#Override

Log.d("onPermissionRequest");
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
request.grant(request.getResources());
}

You can go through the following open source project to find how others solved this problem. This can help you to improve/fix your code. A direct link to a code snippet of interest: Getting camera permission in SmartWebView.
Android Smart WebView. Open Source Project to upload files, get GPS locations and more advanced features
Also, your codes don't have any image capture intent or any file chooser method, you need them to use the camera and also file creation method to write a new image to the device. And, in your Manifest, you need to have WRITE_EXTERNAL_STORAGE permission to write new files to the device for upload.
Hope it helps.

It looks like your input tag might be mal-formatted.
Try this. It's for the new HTML Media Capture spec
<input type="file" name="file" accept="image/*" capture>
Or try this older version
<input type="file" name="file" accept="image/*" capture="camera">
Edit...
Or better yet, use an intent.
Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(takePictureIntent, REQUEST_IMAGE_CAPTURE);

button does not respond in Webview

Everything in the android web app is working as expected except the html file input fields coded as <input type="file" name="filn"/> in webpage.When i click on the button supposed to load the resources in which the files can be chosen from, it does not respond. Meanwhile in google browser, it works fine. My webview android code is as follows:
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
webview =(WebView)findViewById(R.id.webView1);
webview.setWebViewClient(new WebViewClient());
webview .getSettings().setJavaScriptEnabled(true);
webview.loadUrl("website");
}
What can i do to make it work?
present class which does not work also. I am trying to load a file from html file input in a jsp.
public class WebViewActivity extends Activity {
private String url = "website";
private ValueCallback<Uri> mUploadMessage;

#Override
protected void onActivityResult(int requestCode, int resultCode, Intent intent) {
if(requestCode==FILECHOOSER_RESULTCODE) {

mUploadMessage.onReceiveValue(result);
mUploadMessage = null;
}
}

Enable attachment in WebView android

I have been trying to make my app let the user upload pictures from locel drive inside the webview from inside my app.
I used this code to do the pop up webview:

import android.os.Bundle;
import android.view.View;
import android.view.Window;

import android.webkit.WebView;
import android.widget.Button;
public class WebViewDialogActivity extends Activity
{
//Create a dialog object, that will contain the WebView
private Dialog webViewDialog;
//a WebView object to display a web page
private WebView webView;
//The button to launch the WebView dialog
private Button btLaunchWVD;
//The button that closes the dialog
private Button btClose;
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.sliding_menu_categories);
//Inflate the btLaunchWVD button from the 'main.xml' layout file
btLaunchWVD = (Button) findViewById(R.id.bt_launchwvd);
//Set the 35. OnClickListener for the launch button
btLaunchWVD.setOnClickListener(new OnClickListener()
{
#Override
public void onClick(View v)
{
//Display the WebView dialog
webViewDialog.show();
}
});
//Create a new dialog
webViewDialog = new Dialog(this);
//Remove the dialog's title
webViewDialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
//Inflate the contents of this dialog with the Views defined at 'webviewdialog.xml'
webViewDialog.setContentView(R.layout.webviewdialog);
//With this line, the dialog can be dismissed by pressing the back key
webViewDialog.setCancelable(true);
//Initialize the Button object with the data from the 'webviewdialog.xml' file
btClose = (Button) webViewDialog.findViewById(R.id.bt_close);
//Define what should happen when the close button is pressed.
btClose.setOnClickListener(new OnClickListener()
{
#Override
public void onClick(View v)
{
//Dismiss the dialog
webViewDialog.dismiss();
}
});
//Initialize the WebView object with data from the 'webviewdialog.xml' file
webView = (WebView) webViewDialog.findViewById(R.id.wb_webview);
//Scroll bars should not be hidden
webView.setScrollbarFadingEnabled(false);
//Disable the horizontal scroll bar
webView.setHorizontalScrollBarEnabled(false);
//Enable JavaScript
webView.getSettings().setJavaScriptEnabled(true);
//Set the user agent
webView.getSettings().setUserAgentString("Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.0.4) Gecko/20100101 Firefox/4.0");
//Clear the cache
webView.clearCache(true);
//Make the webview load the specified URL
String url = "http://phppot.com/demo/jquery-contact-form-with-attachment-using-php/";
webView.loadUrl(url);

Please let me know what fixes do I need to apply to the code.
