Android :: How To Use Separate Thread To Perform Http Requests?
Aug 2, 2010I 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.

View 2 Replies View RelatedAndroid :: Perform Several Tasks Synchronously?
Sep 24, 2010I 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?

Android :: Perform Haptic Feedback() ?
Sep 28, 2009I 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?
Android :: No Applications Can Perform This Action Error
Feb 15, 2009I 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?

May 28, 2010I 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?

Jun 2, 2010I am creating a program which requires me to change a setting in the program when the video reaches specific points (at 1/3 of the video's completion, 2/3's and on completion). Android has a built in callback method for completion so performing an action at that point in time is not difficult. However, I don't know how to go about checking when the video has reached 1/3 and 2/3's of completion.

View 1 Replies View RelatedAndroid : Does System Perform A Clean Install Of New Version?
Nov 10, 2010What implications does upgrading an app have on stored data i.e. Preferences and database? Does the system perform a clean install of the new version(i.e. remove the older version and then install the new) or something else? What if the user wants to retain the stored data- say values in the shared preference or a sqlite database? How can I emulate this app-update-install scenario? If I have a version 'x' installed on my emulator and I do a adb install of version 'x+1' I am getting INSTALL_FAILED_ALREADY_EXIST error. Should I try hosting the new apk on a Web server, will the Package Manager take this as an update and do the needful?

View 1 Replies View RelatedAndroid :: Adb Shell Commands To Change Settings Or Perform Tasks On A Phone
Feb 4, 2010How do I use adb to perform some automated tasks on my android phone? I need to find commands that I can issue from the command line (ideally, using a .bat file) that will be capable of more than simply opening an application or sending an input keyevent (button press).
For instance, I want to toggle Airplane Mode on or off from the command line. Currently, the best I can do is launch the Wireless & network settings menu and then use input keyevents to click Airplane mode:
CODE:.................
There are quite a few drawbacks to this method, primarily that the screen has to be on and unlocked. Also, the tasks I want to do are much broader than this simple example. Other things I'd like to do if possible:
1.Play an mp3 and set it on repeat. Current solution:
CODE:..................
2.Play a video. (current solution: open MediaGallery, send keyevents, similar to above)
3.Change the volume (current solution: send volume-up button keyevents)
4.Change the display timeout (current solution: open sound & display settings, send keyevents)
As before, these all require the screen to be on and unlocked. The other major drawback to using keyevents is if the UI of the application is changed, the keyevents will no longer perform the correct function. If there is no easier way to do these sort of things, is there at least a way to turn the screen on (using adb) when it is off? Or to have keyevents still work when the screen is off?
I'm not very familiar with java. That said, I've seen code like the following (source: http://yenliangl.blogspot.com/2009/12/toggle-airplane-mode.html) to change a setting on the phone:
Settings.System.putInt(Settings.System.AIRPLANE_MODE_ON, 1 /* 1 or 0 */);
How do I translate something like the above into an adb shell command? Is this possible, or the wrong way to think about it?
