I use the following codes to detect which UI element is the player pointing. It works well in Unity Editor, on one of my Android phone, but failed on a second Android phone.
public static T RaycastOnFirstPointed<T>(EventSystem eventSystem, GraphicRaycaster raycaster)
{
if (Application.platform == RuntimePlatform.Android || Application.platform == RuntimePlatform.IPhonePlayer)
{
if (Input.touches == null || Input.touches.Length == 0) return default;
}
var m_PointerEventData = new PointerEventData(eventSystem);
m_PointerEventData.position = Input.mousePosition;
var results = new List<RaycastResult>();
raycaster.Raycast(m_PointerEventData, results); // On the 2nd phone the results.length is 0
foreach (RaycastResult result in results)
{
var component = result.gameObject.GetComponent<T>();
if (component != null)
{
return component;
}
}
return default;
}
This method is called within a IEndDragHandler.OnEndDrag method. I tried to debug it on the 2nd Android phone, and saw the results.length is 0 after Raycast was executed.(it should be > 0 since I ended my drag on several overlapped UI elements, and it is > 0 on the 1st phone, not sure why the 2nd phone is different)
I don't have any clue where should I go from here to find the problem. Please show me some directions, thank you!
More info:
Phone 1: MI 8 Lite, OS: MIUI 10.3
Phone 2: MI 9, OS: MIUI 10.2.35
============Update===========
Reason found:
When IEndDragHandler.OnEndDrag is triggered, the Input.mousePosition has different value on the two devices. 1st Phone has the touch position from the last frame, while the 2nd phone seems clears that value, and it has a very large wrong value. I'm working on how to solve this in a proper way. Any suggestions are welcomed.
Problem solved. As I updated in the question, this problem is caused by wrong Input.mousePosition value on different devices. So I updated the RaycastOnFirstPointed method as follows:
public static T RaycastOnFirstPointed<T>(EventSystem eventSystem, GraphicRaycaster raycaster, PointerEventData eventData = null)
{
if (Application.platform == RuntimePlatform.Android || Application.platform == RuntimePlatform.IPhonePlayer)
{
if (Input.touches == null || Input.touches.Length == 0) return default;
}
var m_PointerEventData = new PointerEventData(eventSystem);
if (eventData == null)
{
m_PointerEventData.position = Input.mousePosition;
}
else
{
m_PointerEventData.position = eventData.position;
}
var results = new List<RaycastResult>();
raycaster.Raycast(m_PointerEventData, results);
foreach (RaycastResult result in results)
{
var component = result.gameObject.GetComponent<T>();
if (component != null)
{
return component;
}
}
return default;
}
When call this method within OnEndDrag, pass in the PointerEventData that unity provides and use its position.

I am trying to make a sudoku app, and in it I am generating each puzzle. My generation, I thought, should work flawlessly, yet my app continues to crash. I think it is coming from here and on:
If(_band == 2) {
while((band2.contains(placeholder)) || (band2.get((int)(_stack - 1)).doubleValue() == band1.get((int)(_stack - 1)).doubleValue())) {
placeholder = SketchwareUtil.getRandom((int)(1),(int)(9));
}
band2.add(Double.valueOf(placeholder));
}
This goes from band2 to band9, checking each band before it for a duplicate number in the same position and checking its band for a duplicate number.
If it helps, band3 generation looks like this:
If(_band == 3) {
while((band3.contains(placeholder)) || (band3.get((int)(_stack - 1)).doubleValue() == band1.get((int)(_stack - 1)).doubleValue()) || (band3.get((int)(_stack - 1)).doubleValue() == band2.get((int)(_stack - 1)).doubleValue())) {
placeholder = SketchwareUtil.getRandom((int)(1)), ((int)(9));
}
band3.add(Double.valueOf(placeholder));
}
The error code is always:
Invalid List Operation
: Index: 0, Size: 0
I've noticed using the latest build of Codename one.
When my sidemenu (hamburger menu) is on the right hand side, the shadow image is flipped.
Seems to be the case on the simulator and Android and iOS.
I seem to remember I had to put in a work around to get this working recently, but that work-around doesn't seem to work anymore.
I tried to replace the imahe using the theme constants, and also to turn it off by setting sideMenuShadowBool to false. but neither of these seem to do anything anymore.

Code snipit (called on beforeShow for each form):

if (handler == null) {

sm.addCommandListener(handler);
}
for (int c = 0; c < f.getCommandCount(); c++) {
f.removeCommand(f.getCommand(c));
}
Toolbar tb = new Toolbar();
f.setToolbar(tb);
fc.setupTitlebar(tb);
String formName = f.getName();
if (!"Main".equals(formName)
&& !"Signup".equals(formName)

addSideCommand("View T&Cs", "TnCSideOption", TANDC, e->showTandCs(), tb);

}
}
private void addSideCommand(String name, String udid, int commandID, ActionListener event, Toolbar tb) {
Command command = new Command(name, null, commandID);
command.putClientProperty(SideMenuBar.COMMAND_PLACEMENT_KEY, SideMenuBar.COMMAND_PLACEMENT_VALUE_RIGHT);
Button comandLabel = new Button(name);
comandLabel.setUIID(udid);
command.putClientProperty(SideMenuBar.COMMAND_SIDE_COMPONENT, comandLabel);
tb.addCommandToSideMenu(command);
comandLabel.addActionListener(event);

This issue should be resolved and will be in the release this Friday (June 3rd 2016)
I created an app using Unity3D. After developing it for some weeks I tried to generate an apk and test it on my SGII.
Unity returns no errors or warnings when testing the app locally, but when it runs on my phone, it doesn't work.
There are 2 buttons (1 to clock in and 1 to clock out from work). Button 1 takes the date when you clock in, and switches a boolean to allow you to clock out. When running in my phone, button 1 works fine but button 2 doesn't. The button works actually, since it returns every debug.log, but nothing else.
My code looks like this:
function OnGUI()
{
GUI.skin = skin;
if(Functions.firstTime == 0)
{
Functions.setupWiz();
}
switch(currentMenu)
{
case 1:
GUI.BeginGroup(Rect(0, 0, width, height));
if(Functions.birthday == true)
{
debugLog11 = "\n"+happyBirthdayMsg+", "+Functions.userName+"!";
Functions.birthday = false;
}
if(GUI.Button(Rect(buttonTopHMargin,height*.1f + buttonTopVMargin, width*.24f, height*.1f), "ENTRADA", "Box"))
{
if(!clockedIn && clockedOut)
{
var clockIn = Functions.clockIn();
debugLog11 = "\nHora de entrada";
debugLog12 = "\n"+clockIn[3]+":"+clockIn[4]+":"+clockIn[5];
clockedIn = true;
clockedOut = false;
}
else
{
debugLog11 = "\n"+errorMsg1;
debugLog12 = "\n";
}
}
if(GUI.Button(Rect(width - buttonTopHMargin - width*.24f, height*.1f + buttonTopVMargin, width*.24f, height*.1f), "SALIDA", "Box"))
{
if(!clockedOut && clockedIn)
{
// debugLog11 = clockedIn+"\n"+clockedOut;
Functions.clockOut();
var clockOut = Functions.clockOut();
var workedSecondsToday : Array = Functions.calculateDay();
var workedTimeToday = Functions.convertSeconds(parseInt(workedSecondsToday[0].ToString()));
var extraTimeToday = Functions.convertSeconds(parseInt(workedSecondsToday[1].ToString()));
var festTimeToday = Functions.convertSeconds(parseInt(workedSecondsToday[2].ToString()));
if(parseInt(workedSecondsToday[0].ToString()) > 0 && parseInt(workedSecondsToday[1].ToString()) < 1 && parseInt(workedSecondsToday[2].ToString()) < 1)
{
debugLog11 = "\nHora de Salida\nNormal:"; //NORMAL
debugLog12 = "\n"+clockOut[3]+":"+clockOut[4]+":"+clockOut[5]+"\n"+workedTimeToday[1]+":"+workedTimeToday[2]+workedTimeToday[3];
}
else if(parseInt(workedSecondsToday[0].ToString()) > 0 && parseInt(workedSecondsToday[1].ToString()) > 0 && parseInt(workedSecondsToday[2].ToString()) < 1)
{
debugLog11 = "\nHora de Salida\nNormal:\nExtra:"; //NORMAL + EXTRA
debugLog12 = "\n"+clockOut[3]+":"+clockOut[4]+":"+clockOut[5]+"\n"+workedTimeToday[1]+":"+workedTimeToday[2]+workedTimeToday[3]+"\n"+extraTimeToday[0]+"-"+extraTimeToday[1]+":"+extraTimeToday[2]+":"+extraTimeToday[3];;
}
else if(parseInt(workedSecondsToday[0].ToString()) > 0 && parseInt(workedSecondsToday[1].ToString()) < 1 && parseInt(workedSecondsToday[2].ToString()) > 0)
{
debugLog11 = "\nHora de Salida\nNormal:\nFestivo:"; //NORMAL + FESTIVO
debugLog12 = "\n"+clockOut[3]+":"+clockOut[4]+":"+clockOut[5]+"\n"+workedTimeToday[1]+":"+workedTimeToday[2]+workedTimeToday[3]+"\n"+festTimeToday[0]+"-"+festTimeToday[1]+":"+festTimeToday[2]+":"+festTimeToday[3];
}
else if(parseInt(workedSecondsToday[0].ToString()) > 0 && parseInt(workedSecondsToday[1].ToString()) > 0 && parseInt(workedSecondsToday[2].ToString()) > 0)
{
debugLog11 = "\nHora de Salida\nNormal:\nExtra:\nFestivo:"; //NORMAL + EXTRA + FESTIVO
debugLog12 = "\n"+clockOut[3]+":"+clockOut[4]+":"+clockOut[5]+"\n"+workedTimeToday[1]+":"+workedTimeToday[2]+workedTimeToday[3]+"\n"+extraTimeToday[0]+"-"+extraTimeToday[1]+":"+extraTimeToday[2]+":"+extraTimeToday[3]+"\n"+festTimeToday[0]+"-"+festTimeToday[1]+":"+festTimeToday[2]+":"+festTimeToday[3];
}
clockedOut = true;
clockedIn = false;
}
else
{
debugLog01 = mainMsg;
debugLog11 = "\n"+errorMsg2;
debugLog12 = "\n";
}
}
Can't explain myself better since I have no clue about what is happening. Any help will be much appreciated.
Yesterday, i started placing tons of labels everywhere in my code and finally discovered where it stopped.
It was just replacing this...
var sw = new StreamWriter(Application.persistentDataPath+"\\Settings.txt", false);
by...
var sw = new StreamWriter(Application.persistentDataPath+"/Settings.txt", false);
Only windows supports this bar "\" when used for setting paths, but i was thinking all the time that the error was somewhere in the OnGUI function.
Thanks lot to everyone who came helping me :)
On the Unity3D you can find this information:

Unity3D Android Limitations
I am using bootstrap typeahead.
It depends on this jQuery code to work:
el.on('keyup', doSomething() )
On Chrome on Windows it works fine. On Chrome on Android it doesn't. The keyup event is never fired. The element to which it is bound definitely has the focus.
This appears to be a recent development.
Chrome 28.0.1500.64
Android 4.1.2 SGP321 Build/10.1.1.A.1.307

I came across this same problem earlier today. How can android chrome not support these key events! I assume you've found a workaround by now, but here's a fix that I came up with for now.
function newKeyUpDown(originalFunction, eventType) {
return function() {
if ("ontouchstart" in document.documentElement) { // if it's a touch device, or test here specifically for android chrome
var $element = $(this), $input = null;
if (/input/i.test($element.prop('tagName')))
$input = $element;
else if ($('input', $element).size() > 0)
$input = $($('input', $element).get(0));
if ($input) {
var currentVal = $input.val(), checkInterval = null;
$input.focus(function(e) {
clearInterval(checkInterval);
checkInterval = setInterval(function() {
if ($input.val() != currentVal) {
var event = jQuery.Event(eventType);
currentVal = $input.val();
event.which = event.keyCode = (currentVal && currentVal.length > 0) ? currentVal.charCodeAt(currentVal.length - 1) : '';
$input.trigger(event);
}
}, 30);
});
$input.blur(function() {
clearInterval(checkInterval);
});
}
}
return originalFunction.apply(this, arguments);
}
}
$.fn.keyup = newKeyUpDown($.fn.keyup, 'keyup');
$.fn.keydown = newKeyUpDown($.fn.keydown, 'keydown');
Sorry to say this but keyup/keydown events do not work for chrome browser in android.
There are other people who have reported this issue(Here and Here) from last 1 year and its not fixed yet. so it's better for developers to avoid using these events till it gets fixed.
Just want to call a login function once after someone clicks a video thumbnail. This is what I have:
if (videoCode == "BQXTCCyJsKE" && $secCode == null){
var $secCode = "1";
$(document).ready(function () {
login()
});
}
You would think $secCode would equal "1" later on, but NO. It becomes null again and the login function is called again which gives an error. I've tried making global variables but it doesn't work. Anyone have any ideas?
Writing in the answer box for better formatting, here is what I would have expected:
var secCode = null; // I am global
if (videoCode == "BQXTCCyJsKE" && secCode == null){
secCode = "1";
$(document).ready(login());
}
