I am developing an android application and I am novice in Touch enabled Android Application. I have read the article about "onFling" and "onScroll" event on:
http://developer.android.com/reference/android/view/GestureDetector.OnGestureListener.html
But I didn't get exactly what is the meaning and for what we can use OnFling and onScroll event?

I am using gesture detector to catch "flings" and using a view flipper to change the screen when this happens. Some of my child views contain list views. The the gesture detector wont recognize a swipe if you swipe on the list view. But it will recognize it if it is onTop of TextView's or ImageView's. Is there a way to implement it so that it will recognize the swipes even if they are on top of another view that has a ClickListener?

View 2 Replies View RelatedHas anyone implemented an Android Shake Detector that works well on most phones?I thought it would be fairly simple to implement but I keep getting false results. Basically, what I'm doing is setting up a sensor Listener, checking to make sure it is a SensorManager.SENSOR_ACCELEROMETER event, then only checking the event if the last event I received was more than 50 milliseconds ago (to try to reduce the amount of checking I do).Then I look for 3 "Shakes" within 4 seconds.A "Shake" to me being a speed reading of over 1000 followed by a speed reading of less than 400 within 1 second. If I don't get three "Shakes" within 4 seconds then the counter is reset to zero.At times it seems to work well but I continue to have instances where I just pick up the phone, and it triggers all three shakes, which makes very little sense to me because at other times, I can physically shake the phone quite hard, and not trigger all three shakes.As I said.. it works about 90% of the time correctly, but a 10% error rate is making the feature I want to implement useless.

View 5 Replies View RelatediFMW was upgraded: Mobile site for public person or private file share for secret person in one app.
It has two inversion functions on one app.
Public person can get his/her own public web site on the phone and secret person can use only private file sharing directly on the phone without uploading.
Those who want two demands above will use whole functions.
What will you choose of those choices?

When ever we need to send an email in Android we will invoke registered email application using Intent.ACTION_SEND. like the below
Intent i = new Intent(Intent.ACTION_SEND);
startActivity(Intent.createChooser(i, "Send mail..."));
My doubt is why do we need to use Intent.createChooser in startActivity rather than using
startActivty(i).
Is there any specific reason of using Intent.createChooser()?
I'm reading the android source code, and wanna make orientation animation. I've found that when I rotate the screen, the code will be executed to public boolean setRotationUncheckedLocked(int rotation, int animFlags){}, in which there's a line startFreezingDisplayLocked(). If this method works, there's no animation when I rotate the screen. Thus, I wanna know whether Google forbid orientation animation on purpose, and if I wanna make an animation, whether just use stopFreezingDisplayLocked() instead? Thanks a lot.

Is it true that most of the devices out there are compatible with my code if I compile it for the default arm processor, or will I find that there are many devices out there that my library won't run on? What I'm asking is, should I maintain java code that does the same thing as my jni library for compatibility purposes, or is it safe to have jni libraries alone? How large is the group of devices that cannot use the libraries I write? Where are there stats regarding what population is using processors other than the arm processors?

View 8 Replies View RelatedI want to capture Intents with a specific Uri pattern that uses the http scheme. I DO NOT want the chooser dialog to pop up. The Android API advertises filtering of intents based on pattern matching of the path part of the Uri:http://developer.android.com /guide/topics /manifest/data-element.html However, when I try to specify a pattern for my path other than ".*" (which pops up the chooser, which I'm trying to avoid), it doesn't work, and the browser automatically handles the Intent. So, my question is, what is the purpose of the pathPattern/pathPrefix if, for the http scheme, it either auto resolves to the browser, or pops up the chooser anyways?
View 1 Replies View RelatedI would like to know what is meant by gestures in typical mobiles more specifically android ones. Android supports gesture recognition.
Is a gesture termed as when user holds the device and shakes it(say upwards, downwards or side- side)?
Is a gesture termed as when a finger is placed on the screen and traced UP,DOWN,RIGHT,LEFT? If so what is the difference between touch screen and gestures.
I am confused between 1) and 2) option.
What is a gesture exactly?
I create some gestures and they are working, but if I add a button the gesture doesn't work over the button. I split the display resolution to make different gestures and i get x, y coordinates. If i make a gesture starting with the button the coordinates are both 0, only under them i get normal coordinates. It's like the coordinates are starting only after the button.

I had developed a simple gesture recognition library for Android (not for accelerometer; I mean touchscreen - finger gestures). I had to abandon it for quite a while, but recently I was able to clean it a bit and port it to 1.0 SDK. It is released under GPL. Here are some sample videos:

Me and some of my friends have made a gesture recognition application for android. It allows you to customize gestures that will call, text, or email one of your contacts or launch an application. Please check out our blog and demonstration video and comment to let us know what you think.
I got pretty good at using the Palm shorthand for entering text. I'm pretty sure that a similar "shorthand keyboard" would work out well on the Android phones, but I haven't seen any apps that will replace the keyboard with a "shorthand" pad.
View 2 Replies View RelatedI have hooked in a ScaleGestureDetector to an OnTouchListener as instructed in Android documentation. For some reason the ScaleGestureDetector does not always detect end of a pinch gesture. This happens mostly when pinching fast from large to small.
The effect is that after I have released both fingers the detector does not fire the gesture end event. If I touch the screen with one afterwards it still thinks I'm continuing the scale gesture (keeps firing onScale events). I have to do another gesture to get the detector to fire end event.
I have added logs to the OnTouchListener and when the scale gesture gets stuck I still get motion events normally when using one finger and event.getPointerCount() is 1.
I have made sure that I don't have any other listeners intervening. View that has the onTouchListener is not the only view on screen but this effect happens also when I'm very careful to begin and end the gesture inside this one view.
Is there any way to improve the end detection?
Or if there a way for me to manually set the ScaleGestureDetector to fire onScaleEnd and change scaleGestureDetector.isInProgress() to false?
What I want is to have an options menu where the user can choose to navigate the menu between:
1) touching a button and then pressing down on the trackball to select it, and
2) drawing predefined gestures from Gestures Builder
As it stands now, I have created my buttons with OnClickListener and the gestures with GestureOverlayView. Then I select starting a new Activity depending on whether the using pressed a button or executed a gesture. However, when I attempt to draw a gesture, it is not picked up. Only pressing the buttons is recognized. The following is my code:

where do I put this in my code, do I have to create a new class for it, or can I have it in an inner class, or does it not need a class at all?! I have a set up similar to Lunar Lander which comprises of two files, one of which is a thread that handles pretty much all the physics and drawing of the game. The other file begins the thread and saveInstanceState method. Furthermore, what type is mLibrary?! I cannot find out anywhere! I imagine I will put the OnGesturePerformed method in my thread as this is where I handle all keyUp and Down events.
How do you use the Android API to zoom in and out maps with the 2 finger gestures like iPhone?
