Android :: Want To Catch Taps But Not Scrolling In Javascript In Droid
Nov 9, 2010I'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.

Android :: Can't Catch OutOfMemoryException?
Aug 19, 2009I'm writing an app dealing with JPEG pictures. The main Activity let the user slide between a set of pictures, but if these pictures are too large (imagine a set of pictures taken with a 12Mpix camera, not resized), the pre-loading of the second picture throws an OutOfMemoryException that leads to an immediate app VM shutdown whereas I surrounded my calls to BitmapFactory.decodeXXX() whit a try/ catch(Exception). So, the user gets an error message making him think the app is unstable, and the app didn't have any chance of telling him what really happened. How can I handle this a more "user friendly" way? Can I predict the memory size that will be necessary to load a compressed JPEG picture?

Jan 11, 2010I was in my jeep the other day when I heard a ad for some song and a itagging...That got me thinking. Now before the fanboy name calling starts, this is not a comparison to iPhone. I have never owned one, nor shall I ever. I think for the android based phone to compete more with the whole iphone market, I think we need to develop our own brand of iTagging, our own brand of iPhone docks, and our own version of iTunes. I understand that the iPhone has been out for a long time and has had the media market to back it up. Heres the thing. There are way more versions of android based phones that there will be of iPhones. I know that there are a lot of variations of the phones, but its nothing adapters cant fix for the docks. as for the itagging, and the itunes apps, its nothing a dev cant handle. I am not a Dev, nor am I a manufacturer, but Im sure some of us can find a friend of a friend who knows this guy that lives down the street to help out our cause...

View 2 Replies View RelatedAndroid :: Stop Application Catch
May 25, 2010I have five screen in my application. While in performing one action in fifth screen I encountered with Stop Application message. On which, I am getting 3 times "Stop Application" msg box, which covers 3 previous screen and comes back to the first screen. I understand I must have encountered with Error may be IndexOutOfBoundException which I have not addressed it in my code. I was wondering why it asks for extra 3 times "Stop Application" system message. It is fine to display an "Stop Application" system message if I encountered an error in any screen it should stop that particular screen and should come to the next screen on. How can I trap/catch such incidents not to occur in the consecutive screen. If the above description is not clear at any place please let me know that I be more clear to you.

Android :: How To Catch Map Zoom In / Out Event
Jan 14, 2010Does anybody know how to catch the map zoom in/out event for Android 1.5?Before Android 1.5, I can use ZoomControls which has a setOnZoomInClickListener(). In order to get zoom controls, I can write like this:ZoomControls mZoom = (ZoomControls) mMapView. getZoom Controls(); But, since 1.5, the mMapView.getZoomControls() is deprecated. Instead of this, the documentation suggests using mMapView.setBuiltInZoomControls.Since 1.6, I can use ZoomButtonsController, which has a set OnZoomListener(). In order to get zoom button controls, I can write like this:ZoomButtonsController mZoom = (ZoomButtonsController) mMapView.getZoomButtonsController().setOnZoomListener(this);So, how can I get map zoom in/out event without using mMapView.getZoomControls() for Android 1.5 ?

Jan 6, 2010I'm getting this error: "Uncaught handler: thread main exiting due to uncaught exception java.lang.VerifyError" It's only happening on 1.6. Android 2.0 and up doesn't have any problems, but that's the main point of all. Can't catch the Error/Exception (VerifyError), and I know it's being caused by calling isInitialStickyBroadcast() which is not available in SDK 4, that's why it's wrapped in the SDK check. I just need this BroadcastReceiver to work on 2.0+ and not break in 1.6, it's an app in the market, the UNDOCK feature is needed for users on 2.0+ but obviously not in 1.6 but there is a fairly amount of users still on 1.6.
private BroadcastReceiver mUndockedReceiver = new BroadcastReceiver()
{
@Override
public void onReceive(Context context, Intent intent)
{
//FROM ECLAIR FORWARD, BEFORE DONUT THIS INTENT WAS NOT IMPLEMENTED
if (Build.VERSION.SDK_INT >= 5)
{
if (!isInitialStickyBroadcast()) {
int dockState = intent.getExtras().getInt("android.intent.extra.DOCK_STATE", 1);
if (dockState == 0)
{
finish();

Android :: How To Catch Intent For Opening Webpage?
May 21, 2010I am trying to catch the intent that is fired when someone clicks on a hyperlink to a web page in the MMS browser. I have this in the manifest:
</intent-filter> <intent-filter>
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<data android:scheme="http" /> </intent-filter>
However, when I click on http://www.ibm.com it only launches Browser. Same when I do
$ am start -a android.intent.action.VIEW -d http://www.ibm.com
in an adb shell.
Android :: Catch When Press Home Button?
Nov 4, 2010I am trying to catch when the user has pressed the Home button. I thought I could use
protected void onResume()
{
registerReceiver(homeReceiver, new IntentFilter(Intent.CATEGORY_HOME));
}
...
private BroadcastReceiver homeReceiver = new BroadcastReceiver()
{
public void onReceive(Context context, Intent intent)
{
// logic here
}
};
but that doesn't seem to work. I understand that onPause will be called, but my particular app has some logic that I need to handle separately. Short story is based on some info coming in, the app will display new Activities to the user. To prevent Back button issues, as each Activity hits it's onStop it calls finish on itself. However if the user presses the Home button I do not want the Activity to call finish so that when the user presses the app icon on the home screen or via the Recently run apps list, the last Activity is brought back
Android :: How To Catch An Incomming Text Message?
Apr 24, 2010I want to be able to control incoming text messages. My application is still on a "proof of concept" version and I'm trying to learn Android programming as I go. First my application need to catch incomming text messages. And if the message is from a known number then deal with it. If not, then send the message as nothing has happened to the default text message application. I have no doubt it can be done, but I still have some concern and I see some pitfalls at how things are done on Android. So getting the incomming text message could be fairly easy - except when there are other messaging applications installed and maybe the user wants to have normal text messages to pop up on one of them - and it will, after my application has had a look at it first. How to be sure my application get first pick of incomming text messages? And after that I need to send most text messages through to any other text message application the user has chosen so the user can actually read the message my application didn't need.
