Android :: How To Create Raw File Of Android Gestures?
Aug 20, 2010
I have noticed in the android gesture examples, that it reads the gestures from the res/raw folder. it would be a great thing for my application to include a 'getting started' list of gestures. that way a user can use the app without having to train it for their own personal gestures. i would even expect that the majority of users would be happy to use a default set of gestures.however, i cannot figure out how to generate that initial set of gestures that i would include in the res/raw folder of my application.anyone have ideas of how to create this file or where to look for more info?

WebView can scroll on both axis. That makes it hard to integrate with the 1.6 gestures. At the same time a WebView is often used as the main and huge content area, so either there is a way to work with gestures properly or gestures can't be used in lots of places.
Did anybody do this and has recommendations on how to do that properly?
The main problem I see is that a scrolling in any direction can be interpreted as a gestures and which keeps the user from scrolling. And because this is an issue for any direction I can't workaround the problem with only using horizontal or vertical gestures.
The best solution I found so far is canceling the gesture when no new onGesture events occur for 200ms. And with the finger still on the screen the user can then scroll. But that sounds better than it is, as scrolling often requires to pull up the finger again, when the end of the screen is reached, and put it down again on the opposite side, to keep on scrolling. But then the next touch down needs to wait the delay again, which is not very intuitive and as it can lead to a gesture being executed this is even less cool.

Need some information on Gestures. How does android treat Operations like Fling which are at device level? Are they treated as Gestures? I am not able to see any gesture listner code in Launcher (Home screen ) application. If i want to change ( add/remove/modify ) the behaviour of Fling operations where i should start looking in the android code base?

I'm trying to scroll the ListView up/down actions by pressing a button, instead of using finger gesture. It looks like the super class AbsListView.onTouchEvent(MotionEvent ev) handles all the scrolling up/down motion and animation. So if I want to scroll the list by pressing a button, I don't really have a MotionEvent to pass onto onTouchEvent method for it to work. I tried ListView.scrollTo(x,y), it kind of works but the hidden part of the ListView is not rendered when shown on the screen. I am trying to re-draw the list by using: ListView.invalidate(), ListView.invalidateViews(), list.adapter.notifyDataSetChanged()

I have a love-hate relationship with my G1, with the inability to remap keys at the top of the list. I've looked high and low for information, going so far as to try to decipher pages like this:http://www.kandroid.org /android_pdk/keymaps_keyboard_input.html and even reading the android platform code on github. I don't see things like page_up and page_down defined in the android keymappings. And I suspect that the original scancodes are being assigned to touch gestures.Since the number keys don't have a third component could an enterprising developer map to the unused caps for missing keys? Not that it would be all that useful at this point but it would give someone a hook to build on. Or if that isn't possible, how about a virtual floating task bar kind of thing (maybe mostly transparent overlay?) that maps gestures like the swipe up/swipe down and more traditional arrows and enter type keys for the trackball? This isn't entirely a nit-picky kind of request. I have a medical condition that in the winter makes my fingertips extremely painful and the trackball hurts. I'm guessing that there weren't many arthritis sufferers on the Android development team, either. You would think that the touch screen should make things easier, not harder. Even my old, old Omnigo and HP100LX had utilities to remap keys, so it seems odd that there isn't some kind of app that could be developed. I think if I had enough time (which I don't) I might be able to eventually puzzle out a crude version of the task bar thing but I'd much rather pay a couple of dollars in the market.

Was wondering if there's any way to test Gestures (eg: Fling) on the Emulator.
I saw a project on google code that lets people simulate the accelerometer, but none of Gestures.

I would like to define an ImageView in Xml, and then listen to gestures which occur only on that ImageView. But, it appears that the constructor for GestureDector requires an Activity as a parameter, and then responds to gesture events on all components in that Activity. Is there any way to limit this such that events are only generated for gestures upon the pre-defined ImageView?

I have a small piece of code that just won't write a file to the SD card on Android I made sure I created the folder CACHE_DIR before. It exists on the SD card, but canWrite() always returns false. This is the path: /mnt/sdcard/Android/data/org.my.app/files/thumbnailcache I can browse the directory /mnt/sdcard/Android/ data/org. my.app/files/thumbnailcache. Here comes the interesting part: When I try to write to /mnt/sdcard/Test/, it succeeds.How is that possible?

I want my android application to create a .js file, which can then be read by my web view. I have read that the "assets" file is ready only so I cannot save a file to there during runtime. I am saving it in the default "/files/" directory.
I want to be able to reference this file from my webview HTML file. The webview is showing local html files stored in the assets folder. What is the file directory I should use to reference this the .js file in the .html file?

Actually I am new to android. I want to create a .txt file programatically, save data to it and then retrieve the data. I had write one application for that but when I run it it creates file under data/data/ <myPackage Name>/files folder , I can see only size of this file but I can't open it. but when I deploy the application on mobile then there is no any file created. If i supplied path like FileOutputStream fOut = openFileOutput ("/sdcard/ deore.txt",Context.MODE_WORLD_WRITEABLE); then it throws Exception. So, please tell me where the actual file is saved under the phone and how to open it.

I am new to Android and creating my first application.I want to create a file in the current directory. Basically I have a file bundled with aplication package as raw resource. I want to make a copy of this file in the current file. The reason to create copy in current directory is that I want my file reading code in native java, portable code.So my query is how can I create a file on current directory? The location current directory is important here as I do not want to make use of device specific hardcoded path or any Android API while reading the file. This is so I want my file reading code portable.
