[r103]Prevent touch events from trigger twice

Touch object with "Use mouse input" set to "yes" triggers twice on my Samsung. Bug or feature?;)

Tested on a Samsung Tab 2 10.1 with Android 4.0.4. in the pre-installed browser.

Here's the capx:

touchFiresTwiceOnAndroid.capx

And here's a direct link to a published version:

index.html (the textfield should increase by 1 on every touch of the square)

I would really appreciate it if you guys could test it on your Samsung/Android device and post a feedback:) Or know what's causing this. Or have a solution/workaround:)

It's probably registering multiple touches with each tick. Try adding a second condition - On Touch End - to your event.

I always use a combo of On Touch End and Is Touching Object to capture a single tap.

Yeah what Stevo said.

I had a hard time fixing my Capx, because double clicks would <img src="smileys/smiley35.gif" border="0"> it up completely.

I would also not count on "trigger once" to much.

Very simple fix here:

Event:                  Action:

OnTouched

If numTouched < 1       Add 1 to numTouched

Will only trigger once :)

Stevo: I tried it, but it didn't solve the problem. My guess is that it's registrating a mouse click in addition to the touch event.. (Whaat?!)

I'll test a little more and get back to you.

Schoening: Yes, I guess that's the only way to make it work.

Thanks both for your tips!

I've done a little more testing and it turns out it's browser specific. Both Chrome and Firefox works as expected on the same Samsung tablet, leaving the pre-installed browser to blame.

Motorola Xoom with Android 4.0.3 also triggers events twice.

These tablets only triggers once:

Samsung Galaxy Tab - Android 2.3.3

Google Nexus - Android 4.1 (Chrome browser pre-installed)

Asus Transformers - Android 4.0.3 - AppleWebKit/534.30 Safari/534.30

Sorry for necroposting, but I'm also having this problem. How did you fix it, gerris?

To me, it only happens when I export with XDK to android.

What Schoening said, you have to have a flag to check if touched for the first time (Madonna style ;D)

I had similar issue. Taps on phone/tablets were registering as 2 taps but on my windows PC the mouse click registered correctly as 1.

I added a second condition to my event "Is on mobile" which fixed it on mobile but disabled my mouse on my PC.

I tried to add another event that tests if "On HTML5 website" platform but that messed it up on mobile again. Currently, while still in development I just disable the mouse event before exporting it. The above suggestions did not work at all for me, however it could have been my implementation of the solution rather than a faulty solution. Would like to hear what worked for you alvarop.

For what it's worth I only use "is touching" and "trigger once while true" instead of the on-touched trigger because this always seems to become buggy for some reason. I find that way of triggering is ultimately more reliable across different platforms and, as has already been said, if that still isn't enough then add a has been triggered Boolean to stop it double firing.

Colludium: Thanks for that suggestion.....it worked perfectly for the problem I was having.
