Is there a way I can programatically perform a Fling on a listview? I know there is monkey that does all these things but that requires a computer connection with adb etc etc. I want to do it with my app on any phone, without monkey.

Which method in ListView is handling the fling action (up and down)? I look at the source of ListView, I don't see a GestureDectector there.

Does anyone know how this is implemented? Is this implemented using the standard Android SDK, a Motorola-specific function, or something else?

how can I detect Fling action in my own widget? I have implemented my widget as OnGestureListener.
And like in Gallery, I have a "GestureDetector mGestureDetector = new GestureDetector(this);"
For my onTouchEvent(), I have @Override public boolean onTouchEvent(MotionEvent event) {
// Give everything to the gesture detector boolean retValue = mGestureDetector.onTouchEvent(event); return retValue;
But my public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, float velocityY) is never get claeed.

Came up with a simple image viewer app for 2 images.
Feature:
Left and right swipes will switch the images. Dead simple.
What i'd like to do:
Have up to 100 images.
note:
All my images are in my res/drawable folder.
They're named image1.png to image100.png
I obviously don't want to do:
ImageView i = new ImageView(this);
i.setImageResource(R.drawable.image1);
viewFlipper.addView(i);
ImageView i2 = new ImageView(this);
i2.setImageResource(R.drawable.image2);
viewFlipper.addView(i2);
ImageView i3 = new ImageView(this);
i3.setImageResource(R.drawable.image3);
viewFlipper.addView(i3);
all the way to i100. how do I make this into a loop, which is flexible and reads everything from the drawable folder ( and not be limited to 100 images)?

So my application has a large amount of textual data. Up until this point I've been using forward and back buttons to navigate from section to section. I was impressed with the horizontal scrolling of the Ebook reader from Alkido that is available on the store which uses a horizontal fling gesture to flip the pages. Does anyone have any experience doing something like this? I've done it a number of ways, but none seem to be very smooth or efficient.

View 1 Replies View RelatedI have developed an Android app. Now I want to perform a few operations (i. e. - Reset the settings etc.. ) at the moment the app gets uninstalled from the phone. Is it possible to reigster a listener or a function that is called at the moment the app is removed?
View 2 Replies View RelatedI don't know how to elegantly solve the following task:
I have several blocks of code (operation) to execute. Each block can return true of false to indicate that further execution is possible. Inside of each block I have to use asyncronous methods calls (Because Android is completeley asynchronous).
Example of processing operations (not working now as expected):
CODE:.......
The problem is that inside of the operation I need, for example, display AlertDialog and wait for the input. But after I call dialog.show() my method execute finishes and it returns incorrect result.
Example of the button listener, registerd with AlertDialog is below:
CODE:..........
How should I modify processing of operations to support asynchronous model of Android?
I have done socket communication in a single application it is working fine.
But my requirement is i have opened two emulators and i am able to send sms between those two.
Now i want to run server in one emulator(myavd-5554) and client on another emulator(myavd1-5556)
I have used the following code on Serverside public class TCPServerActivity extends Activity
CODE:............................
I want to invoke the haptic feedback buzz when my ImageButton is pressed, but I am not sure the best way to do it. I first checked that my button was enabled for that, and isHapticFeedbackEnabled() returns true.
Then I am calling performHapticFeedback() with the constant FLAG_IGNORE_GLOBAL_SETTING, as the docs indicate that will be used to override any global settings.
The doc is a little ambiguous, but it does imply that this is something I can call at any time, so I am calling it in the OnClickListener():
CODE:..........
I appreciate that it would be better to call it when the finger first touches the button rather than on the Click event, but I wanted to get it working to start with, before refining it.
Am I barking completely up the wrong tree, or should the above work when I click on the button, because nothing happens?
I am using this code to send an email (with no errors in eclipse), but when I run it in the emulator, I get the "No applications can perform this action." error.String[] mailto = {prefemail}; // Create a new Intent to send messages Intent sendIntent = new Intent(Intent.ACTION_SEND); //Write the body of the Email String emailBody = ""; // Add attributes to the intent sendIntent.setType("message/rfc822"); endIntent.putExtra(Intent.EXTRA_EMAIL, mailto); sendIntent.putExtra(Intent.EXTRA_SUBJECT, "TrackMe Password"); sendIntent.putExtra(Intent.EXTRA_TEXT, emailBody); startActivity(Intent.createChooser(sendIntent, "Email sent.")); Do I need to install some mail app from it? I tried the K9 email app, installed it with adb, but I don't see any changes. Do I need to do something other than installing? Or is there another good program for it?

I don't exactly know how android updates the applications. As far as I've read around here it keeps the SQLite database. So, imagine this scenario: one application that uses SQLite database for persisting data. After a while I release v2 which contains some database changes and I need to update user data in database. How can I make this during the update process ?
View 1 Replies View RelatedI am trying to find a way to goto a database located on the web perform 1 query and close the connection. I have not had any luck with finding an answer, and I really don't know how to solve this.
Internet connection is not an issue, nor is any security issues. Also this cannot be solved with an internal database and this must go across the web.

View 1 Replies View RelatedI want to be able to perform live demos of an app I've been working at conferences. There doesn't seem to be an easy way to get a video feed of what's going on onscreen onto a big screen. We've hooked up the screen capture utility of DDMS and keep hitting refresh. Its not ideal. I'm aware that there are more automatic solutions that continuously cause a refresh, but these don't really provide video, and I'd also like an audio feed. I can frame grab within my app pro grammatically, but the Android SDK's video encoder only supports capturing video feed from the camera. Any ideas? What's the best way to live demo Android apps to large audiences?

View 1 Replies View RelatedI have an application that is performing HTTP Requests (specifically calling the FogBugz API) when the user clicks certain buttons. Right now, I am just creating a service when the application starts, and then calling different methods in that service to complete requests. However, when I do this, there is the usual hang in the UI thread. I have looked at AsyncTask, but am not sure it will do what I want to accomplish. Because I need to instantly parse the XML that the HTTP Request returns, I need to have a process that is able to return this data to the UI thread. Will ASyncTask be able to accomplish this, or is there some other way.
