Android :: Way To Invoke A Web Service Through A Button
Aug 11, 2010
I'm trying to make an app where a button will invoke a web service's API call (it'll be my own web service; the call/functionality is not relevant). I know how to make a new listener that invokes an activity, but that is insufficient here since I'll still need to make a call out to a web service through it. What is it I'm doing here? Is this a service that I'm looking at? content provider that I'll be invoking that somehow gets data from a web service?

I have the Samsung SGS3 running on ICS and I am looking for a possibility to invoke the stock TW app switcher (the one that appears when you keep the home button pressed) via a homescreen widget/button/whatever.
One of the other launchers I've tried (was it Go launcher or Apex?) had such a button at the homescreen: When pressed, the action launched the app switcher.

I have made a Android Widget which displays two articles (title + image). In addition to this, I have buttons for flipping backward and forward through the articles. What I don't understand is how I can change the Widgets RemoteViews when the buttons are pressed. Which should be one of the most basic operations in a widget, however, I can't seem to figure it out.
So... Can I do this with just a OnClickListener in the AppWidgetProvider? Or do I have to create an Activity without a window (visibility = false)?

I created and binded a service in an activity and I would like to know how I can avoiding the android application to stop when I press the back button. When the back button is pressed the onDestroy method is called and I unbinded the service in this method. I try to prevent it by taking care of the back button event and manually call for onStop() method but it always called onDestroy after, why?

I'm having trouble starting a Service to update an AppWidget that I'm creating as an exercise. I'm trying to get the latitude and longitude of spoofed location data from DDMS to display in the widget. The widget uses a service to update the TextView, which may be slightly overkill, but I wanted to follow the template that seems to be common in AppWidgets that do more work (like the Forecast widget or the Wiktionary widget).
Right now, I'm not getting any error messages or strange behavior; nothing at all happens when the button is pressed. I'm a bit mystified as to what might be wrong. Could anyone out there point me in the right direction?
Additionally, if my logic for location is faulty, I'd love recommendations on that too. I've looked at several blogs, the Google examples, and the documentation, but I feel a little fuzzy on how it works.
Here is the current state of the widget:
CODE:.....................

In my Android app, a Service runs in the background and logs GPS readings to a database. The user sees an Activity that presents them with radio buttons. I'd like to also log their currently selected radio button to the database. How can I access the radio button object from the Service?

I am creating an Android service which constantly runs in the background. I'd like to be able to intercept calls to the power button to:
a) prevent the screen coming on
b) handle the power button press in a different manner.This is to enable the user to have a very simple interface to my application and prevent wasting battery powering up the screen when it is not required.
I will probably need an alternative mechanism to actually bring the screen back up (such as an extended key press or similar), but this only becomes relevant if what I'm after is possible.

I need to develop an application with downloads the data at the background and update about the progress in the front.
I guess this can be achieved using services and activity and passing data in between the. But, what I need to do is even if I hit back button and then start the activity again. It should check if the service is running or not. If service is not running it should start one else it should display the data from running service.
Something like music player where music is played by a service at a background and activity displays the information. Even on browsing through other activities of the application or hitting back, state of the music player is maintained.

Sorry if this sounds like a really stupid question, but I'm really struggling to understand the Search Manager documentation. How do I actually invoke a search from the hardware search button in my application? I've added the relevant code to the Manifest file, but pushing the button has absolutely no effect. The API is very unclear - is this something that should be handled automatically from the Activity class, or have I got to override something? Have I got to include a hardware key listener?

I need to invoke skype application and make a call from skype when a 'skype me' link (eg: skype://1866012345) is clicked from a webview. Can someone help how to do this?
I tried the following:
Downloaded skype application from market (in my driod 2.2).
When launching skype, the package invoked is 'skype.android.raider' - as per ADB logs.
So I tried invoking a ACTION_VIEW intent with cmp=com.skype.raider/.ui.call.SplashScreenActivity or cmp=com.skype.raider/.ui.call.SkypeOutCallActivity
and data=Uri.parse("skype://1866012345"). These did not work.
(I also did find a few posts suggesting to use skypelite component, but I guess I should ve skype lite installed for that, which could not find in the market. I assume skype lite is not in market anymore.)
(Also, i have to be able to make a phone call or email when corresponding links are clicked from WebView. As of now, I have added custom handling for each of these, but wondering if webview by default would not support it. Is there any webview setting to be enabled t do this? Any idea??)

I build a website for phones like android and iphone,when users click an url , is it possible for me to invoke some system build in activities like Dialer or SMS)?I want to implement this cause I hope when user click the link with phone number,user can start to call directly. it will open the market app and lead me to the app I search. so I think if we format the url in some way ,maybe it can also open the Dialer app in Android.I know it must be another case when it comes to Iphone,but currently,it is fine enough it works with Android,any one ,any idea ?
