View 2 Replies View RelatedAndroid :: Unable To Get Data From Activity To Service / How Intents Could Pass That?
Nov 24, 2010I am pretty new to this but I was told I could get good help here. A friend and myself are playing around with creating Android apps (using ADT)
Here is how we are trying to make the program: in activity, user sets threshold values for the X and Y axis on accelerometer. When user hits button "Start", startService is invoked and starts TiltService.
TiltService is designed to run in the background always on the phone without user interaction. TiltService constantly compares the threshold with the accelerometer values and will vibrate if they are off.
My problem is I can't seem to get the putExtra() data correctly. I have overridden the onStartCommand in my service but I get the message "unreachable code" when I save the getExtras() to a bundle.
Here is the relevant code (I can post the whole thing, just do not want to clog up page) code...
I thought I understood the basic of how Intents could pass data, but I guess I don't. Is it obvious what I am missing?
Android :: Pass Variables To An Outside Class?
Aug 12, 2010I split my inner View class from my Main class into its own file. In my main class, I have the view set as an onTouchListener which records user movement into a matrix so it can translate and scale the view. After separating it everything works but im unsure how to pass the matrix to the View for onDraw to update. Any suggestions?

Android :: Activity Lifecycle And Static Variables
Jul 14, 2009I just ran into a situation where it looks like a static variable reference is persisted across activity sessions. I didn't expect that because I thought that when an activity exits, it's de-referenced and garbage collected. I am wondering if anyone can shed some (more) light on when the VM eliminates object references for Activities and Services and in particular when static variables get reset to default values?
View 7 Replies View RelatedAndroid :: Previous Set Instance Variables Null When Activity Resumed
Apr 20, 2010I am using an Application object to store app-wide instance data--data that I need to remain in existence for the entire lifetime of the app, so the Application class seems like the proper place to put it. I have just finished reading this thread http://groups.google.com/group/android-developers/browse_thread/threa... that goes into pretty good detail and receives confirmation from Googler hackbod as to how the Application class performs--and from that info it seems this strange behavior I am receiving should not be happening...
Basically, every once in a while when I resume my app in any of its Activities (it is still running in memory so onCreate is not called) I get NullPointerExceptions because instance variables in my Application class are returning null when I request them from my Activity (via a getter method in my custom Application class). It seems as if sometimes Android saves the states of my Activities but deletes all my instance variable data... This can't be an Android problem--there must be something wrong with my code.
Has anyone else ever ran into an issue of this kind? Any ideas as to what may be causing this? I'm not going to post my code here as that won't help anyone, but hopefully someone can point me in some helpful directions.

View 5 Replies View RelatedAndroid :: Pass Data Through New Activity?
Jun 29, 2010In my Android app,I start a new activity with startActivityForResult(). I get the result in onActivityResult() perfectly. My problem is that there is a small bit of data that I know before I start the activity and I need that value to be available in onActivityResult(), too. I tried attaching it to my intent as an extra, but it wasn't attached to the intent that is available when the activity returns the result. I made it work by storing the data in a global variable, but I really don't like that approach. Is there a better, right way to pass data through an activity (instead of just to it)?

View 7 Replies View RelatedAndroid : Pass Image To Another Activity?
Aug 23, 2010I figured out how to pass a String value between activites thanks to this site, however I'm having trouble passing an image. What I'm trying to to is have a user click a button that opens the gallery and allows selecting of a picture. Then I have another button that opens another activity that displays an ImageView. I want to be able to have that ImageView's image be the chosen one from the previous activity.
Here is the class that has the button I'm clicking to open the gallery and retrieve the chosen image: code...
What I'm not sure about is in the OnActivityResult if I should pass the selectedImage or the chosenimage in the b.putExtra("bitmap", selectedimage); line. I tried both but I didn't see an image on the second activity. Also I wasn't sure in the PreviewScreen class if I'm setting the imageview correctly. Any help is appreciated. Thanks.

Android :: How To Set / Pass Values From One Screen (activity) To Another?
Sep 30, 2010How do you set/pass values from one screen (activity) to another? What I have in the R.layout.main view labeled Calculator contains the code for doing calculations. The main.xml contains the layout (view) of the main screen. I have created an options menu which has another screen which shows you setup (R.layout.setup). The dialogsetup.xml contains the layout (view) for it.
When you press the menu button, you get the options menu. If you select "Setup", then it will display the setup screen. Now what I need to do is take the values from the setup screen (radio button and text values) and place them in the main screen so that when you exit the setup screen and go back to the main screen, you can take those values and use them in your main code.

View 1 Replies View RelatedAndroid :: Way To Pass Bundle To Activity Set As Singletask?
Apr 22, 2010So I have a MapActivity that runs an asynchtask that occasionally updates what exactly it's displaying on the map (via a string). I originally pass this string in from the intent when the activity is first created. And then if you click on one of the drawables on the map, it opens a new activity, which can then create a new mapview (same class) with a different string setting. The problem I have is that I only want one instance of the mapview to be running at once. Thus I set android:launchmode="singletask" in the manifest. This works in that it brings the mapactivity to the front, but is there any way to send it a new intent bundle to get a new setting for the string it needs? I tried regetting the extras from the bundle, but it seems to retain the old bundle, not the new intent that was passed to it. I'm not sure I want to do startActivityForResult because the 2nd activity may or may not want to update the original activity. I hope that made sense. I can post code if necessary, but I think that should explain my situation.
View 2 Replies View RelatedAndroid :: Pass Database Results Into New Activity?
Oct 4, 2009I'm working on an app, and one activity has a worker thread that initiates a database query, and if there are results once it has returned I would like to send these results to a new activity that will display them. Unfortunately I don't see a way to pack the Cursor object into the Intent object that I am using to start the new activity. When I was doing Windows Mobile development in the past all I would do is edit the constructor for the window to pass in the data, I've searched around but I can't find a similar solution for Android. What is the best way to pass my database results into the new activity?
