Android :: Want To Catch Taps But Not Scrolling In Javascript In Droid
Nov 9, 2010
I'm making an Javascript web app and I can't for the life of me get the touchstart event to fire. I get the touchmove and touchend events no problem. This is a problem because as I see it the best way to distinguish between a tap and a scrolling motion is to zero a counter on the touchstart event, update it at touchmove and then compare it at touchend. I'm doing this so I can do some action at the end of tap but not a scroll. For instance, it would be very confusing if a page opened for an item in a listed after you finished scrolling down that list, but it would be nice to be able to tap on an item to open its page.
This is what I have..
I never see the touchstart alert. If I scroll the touchend will fire and app__touchMoving will have some sort of decent value. On a side note, I've noticed that sometimes the touchend will seem to fire multiple times.
Am I missing something basic here? Plenty of people say that this should work just fine on Android (and iPhone) yet the first listener never seems to fire.
Update: I should mention that I've been testing on a Samsung Galaxy S running Android 2.1.

I would like to disable the context menu that appears after a long tap (touch and hold) on images in my web application. I've seen posts with different ideas how to do it, but none of them seem to work for me.
Is there a way to do this on Android via HTML/CSS/Javascript?

I am about to develop a web application for smart phones. This app uses some JavaScript code. While testing it on Android devices (Hero, Desire) I noticed that all JavaScript timers immediately stop when the page is moved or zoomed. They never continue. Let's say you have a site which displays web camera images with 5 fps. As soon as you move this page (I mean scroll with finger) the web camera image will never be loaded again. So you can't center or zoom the image at all without stopping the stream. This behaviour is 100% reproducible on all Android devices I tested (1.5, 2.1). It does not appear on an iPhone which continues execution after moving stopped fine.

I want to detect when a user taps anywhere in a view in my Android application. My code looks like this:
linearLayout = (LinearLayout) findViewById(R.id.linearLayout); // main layout
// ...
linearLayout.setOnTouchListener(this);
// ...
public boolean onTouch(View v, MotionEvent event) {
Toast.makeText(this, "Touch!", 1000);
if (event.getAction() == MotionEvent.ACTION_DOWN) {
Toast.makeText(this, "Down!", 1000);
return true;
}
return false;
}
but when I click on the view, I don't get Toast! Do touch events work in the emulator -- or have I got something wrong in my code?

Is there any way to catch crashes in my own android app? Something like a global uncaught exception handler? Just wondering if I could install something like that, then if an uncaught exception is thrown, I could pop up a dialog for the user and ask if they want to mail a dump of the exception to me.

The most irritating feature of touch based systems I think is when you are scrolling and you touch a link and it goes there when you only wanted to continue scrolling is there a way to make it require two taps to open a link.

I have an Android project that contains a class that uses JNI to pull a value from a C function. The C function was built into a library using NDK. The value returned from the C function is in turn used to initialize a variable inside a class when its first loaded. This works fine. However, I also want it to work when the library is missing by providing a default value. So Im using something like this..
Despite the catch, Im still getting a UnsatisfiedLinkError when I try to run this code with the library missing. Why am I not catching the exception? What am I doing wrong?

Is it possible to pass a JavaScript object from JavaScript to Java using addJavascriptInterface()? Something along these lines: var javaScriptObject = {"field1":"string1", "field2":"string2"}; JavaScriptInterface.passObject(javaScriptObject); How would such a call be captured on the Java side? I have no problem setting up the interface to send a string, but when I send an object, I receive null on the Java end.

I've been following a discussion on the apparent lack of JavaScript and Java on Android browsers. One of my hot button applications requires either JavaScript or at least the ability to run a .jar file in order to save data. No one in the other discussion has been able to find a Android browser capable of supporting this application (TiddlyWiki)..

I would like to further annotate the custom markers I have placed on a MapView (using ItemizedOverlay) by displaying a simple text label that appears for a particular item when the onTap event is fired.
This is a trivial exercise in the Google Maps JavaScript API and in MapKit on iPhone, but it is not obvious to me what the best or easiest way to do this is on Android.

Is it possible to write service that can catch any user's click on the touch screen and read text of the click no matter what application currently is active?
For example user click on browser or any other application and that service will know what word is written in the location of the screen.
