Crosswalk (xwalk) pull to refresh not working

I'm using Crosswalk (XwalkView) instead of the default Webview on Android but it seems that the defalt pull-to-refresh functionality doesn't work on Android 4.3. I've tested it on 5.0 and it's ok, but on 4.3 and 4.2.2 it doesn't work. I'm guessing it has to do with < 5.0 ?!
I've tried something like this to enable it, but it failed to work:
//Disable the edge effect and try to enable pull to refresh in case we're using xwalk webviews
if (BuildConfig.IS_XWALK) {
final String INIT_SWITCHES[] = {"Xwalk", "--enable-pull-to-refresh-effect", "--disable-overscroll-edge-effect"};
if (!CommandLine.isInitialized()) {
CommandLine.init(INIT_SWITCHES);
}
}
Any ideas ?

Actually, we already have a JIRA about this feature, please track it here: https://crosswalk-project.org/jira/browse/XWALK-6277.
It has some block issue before, but we will continue investigating how to implement it.

Google has changed Linkify implementation with custom links in Android 5

We've got some custom links in our application that look like that bar.foo://var?parameter=value
Prior Android 5.0.0 bar.foo was not recognised as a link. However in Android 5.0.0 it is recognized as a link and Android will try to open it in the default browser if you click anywhere on bar.foo:. If you however click on //var?parameter=value it will treat it as a customized link and do the stuff that is intended.
Is there any way to prevent this?
This is our Linkify related code:
Linkify.addLinks(this, Linkify.WEB_URLS); // This one is causing the issue. Unfortunately we can't disable it
for (final Pattern pattern : linkPatterns) {
Linkify.addLinks(this, pattern, linkPrefix);
}

Highlight a specific text in WebView android 4.0

I want to highlight a specific (searching) text on WebView. I use the code
myWebView.findAll(txtSearch);
try {
for (Method m : WebView.class.getDeclaredMethods()) {
if (m.getName().equals("setFindIsUp")) {
m.setAccessible(true);
m.invoke(myWebView, true);
break;
}
}
} catch (Exception ignored) {
}
This works great on Android 2.2, but it doesn't work on Android 4.0 and above

Yes, you are right, highlight text on WebView works great on Android 2.2, but he appeared as not working on Android 4.0 and above
look at this link
here

i am also trying this highlight of text ,it is working perfectly on
android version 2.2 but if i am trying the same thing in another
version than the highlight text is not shown and one more thing that
findasync() only works for api 16 .May be using java script can help i
am working on that if it works i'll tell to you.
thanks

Mobile Web - Disable long-touch/taphold text selection

I've seen/heard all about disabling text selection with the variations of user-select, but none of those are working for the problem I'm having. On Android (and I presume on iPhone), if you tap-and-hold on text, it highlights it and brings up little flags to drag and select text. I need to disable those (see image):
I've tried -webkit-touch-callout to no avail, and even tried things like $('body').on('select',function(e){e.preventDefault();return;}); to no avail. And the cheap tricks like ::selection:rgba(0,0,0,0); won't work either, as hiding these won't help - selection still happens and it disrupts the UI. Plus I'm guessing those flags would still be there.
Any thoughts would be great. Thanks!

-webkit-touch-callout:none;
-webkit-user-select:none;
-khtml-user-select:none;
-moz-user-select:none;
-ms-user-select:none;
user-select:none;
-webkit-tap-highlight-color:rgba(0,0,0,0);
This will disable it for every browser going.

Reference:
jsFiddle Demo with Plugin
The above jsFiddle Demo I made uses a Plugin to allow you to prevent any block of text from being selected in Android or iOS devices (along with desktop browsers too).
It's easy to use and here is the sample markup once the jQuery plugin is installed.
Sample HTML:
<p class="notSelectable">This text is not selectable</p>
<p> This text is selectable</p>
Sample jQuery:
$(document).ready(function(){
$('.notSelectable').disableSelection();
});
Plugin code:
$.fn.extend({
disableSelection: function() {
this.each(function() {
this.onselectstart = function() {
return false;
};
this.unselectable = "on";
$(this).css('-moz-user-select', 'none');
$(this).css('-webkit-user-select', 'none');
});
return this;
}
});
Per your message comment: I still need to be able to trigger events (notably, touchstart, touchmove, and touchend) on the elements.
I would simply would use a wrapper that is not affected by this plugin, yet it's text-contents are protected using this plugin.
To allow interaction with a link in a block of text, you can use span tags for all but the link and add class name .notSelected for those span tags only, thus preserving selection and interaction of the anchors link.
Status Update: This updated jsFiddle confirms you concern that perhaps other functions may not work when text-selection is disabled. Shown in this updated jsFiddle is jQuery Click Event listener that will fire a Browser Alert for when the Bold Text is clicked on, even if that Bold Text is not text-selectable.

-webkit-user-select:none; wasn't supported on Android until 4.1 (sorry).

Selecting text on TextView (android 2.2)

How to implement selecting text capability on Android 2.2? I searched Google but can't find a solution.

This is the only way I've found (from google) to support it for android 1.6+, it works but it's not ideal, I think in stock android you can't hold down a webview to highlight until v2.3, but I may be mistaken..
By the way this is for a webview, it might also work on textview, but I haven't tried it
(Note: this is currently what my shipped app is using, so it works with all the phones I've had it tested on, but the only reason I found this question was because I was searching and hoping that someone had come up with a better way by now)
I've just got a menu item called "Select text" which calls the function "selectnCopy()"
#Override
public boolean onOptionsItemSelected(MenuItem item) {
//..
switch (item.getItemId()) {
case R.id.menu_select:
selectnCopy();
return true;
//..
}
}
Which looks like this:
public void selectnCopy() {
Toast.makeText(WebClass.this,getString(R.string.select_help),Toast.LENGTH_SHORT).show();
try {
KeyEvent shiftPressEvent = new KeyEvent(0, 0, KeyEvent.ACTION_DOWN,
KeyEvent.KEYCODE_SHIFT_LEFT, 0, 0);
shiftPressEvent.dispatch(wv);
} catch (Exception e) {
throw new AssertionError(e);
}
}
Notice I've put the select_help string there as a toast, that's just because it's not immediately clear to the user how it's supposed to work
<string name="select_help">Touch and drag to copy text.</string>

The Link #Stefan Hållén provided only worked after API Level 11.
And Android 2.2 is API Lv.8, that's the reason why you cannot get a resource identifier.

Have you set the text to be selectable? like this:
android:textIsSelectable="false" //OR true
See the Documentation for further reference.

After a long and time consuming search, I can't find a component that can select text in textview for android API level <=11. I have written this component that may be of help to you :
new Selectable TextView in android 3 (API <=11) component

An interesting workaround:
You could try displaying your text in a webview.
You just have to write the HTML tags and all of that into your string to display, and it should be selectable using the WebKit browser.
This should be fairly lightweight and transparent to the user, and I think it would solve your problem.
Let me know if you need a code example, it should be fairly simple. Just check out the WebView docs on http://developer.android.com/resources/tutorials/views/hello-webview.html
Best of luck!
