Alright, this might be kinda simple, but I cannot figure out how to do this. How can I change this function to return the String class_name? I know that I need to change the function from void to String, but what else do I need to do? Code...

Edit: Okay, I found a solution. Don't know that it's the proper solution, but it does work correctly. Added to the code below. I'm trying to allow a user to select a number of directories from a checklist, and return them upon clicking a "Submit" button. Here's a snippet of my code. It populates the List View with all the directories on /sd card/, and for the initial selection (of however many I pick) when I submit, the log shows the correct choices returned. However, if I un check an item, and click "Submit" again, it still shows as if all are selected. Do I need to write a handler to un check an item? I thought that was taken care of by the choice Mode selection?

I am (supposedly) catching NullPointerException and returning 0 if that happens. But occasionally I get NullPointerException failure anyway. Is catching it this way no enough to prevent this failure?

Looks like reverseGeocode ( getFromLocation()) is not working in android 2.2. It is not able to fetch the address from the coordinates. It returns null and crashing my app.
In general 2.2 is not stable - 2.1 was much better. UI response , UI rotation when rotate the phone etc doesn't work reliably....

Here in the forums, online, user manuals, etc. What I am looking for: When I am texting, I see above the "A" key is an alt symbol that looks like an arrow pointing to the right with a verticle line.

Can i send it directly as an array? I guess then some seriliazation-deserialization needs to be done. Or If send it as an XML file then how should I proceed? (This is more important)

I have an application that utilizes the phones DeviceID in various ways. I am now getting emails from users who have the HTC Droid Incredible phone that they are getting the error message I have added to the app that is showing the DeviceID being returned is not valid - which means it is either empty/null or the default ID used in the emulator. I require a valid DeviceID to use my app, and the permissions are all set fine in the XML. It works just fine on every other device, and now suddenly it seems to stop working on this phone. Anyone else having this issue? Anyone find out what is causing it? Does HTC now block this ID on this device?

If not can someone find a way (and if possible implement the way into the code I will provide below) to get a value from the variable 'songtoplay' so I can use in another Public Void...
Here is the code:.............
Basically, it gets the value from the Spinner 'hubSpinner' and displays it in a Toast. I then want it to return a value for string variable 'songtoplay' -or find a way to make it global or useable in another Public Void, (Which is will a button, -loading the song to be played)
The FileObserver class doesn't appear to be working as advertised.
I created a class extending the FileObserver class. I initialize the class to watch the path of the sdcard as returned from the Android Environment.getExternalStorageDirectory function. Everything seems to work perfectly as long as the files are in the ROOTof the sdcard. Any files within SUB-FOLDERS of the sdcard are NOT returned to my public void onEvent(int event, String path) callback in my FileObserver class.
The docs say files in subfolders should be returned to the onEvent() callback but it's not happening. Note, I've only tested on the Android simulator (v2.2) since I do not yet have access to a device. Maybe this is a bug specific to the simulator?
I have an application that needs to have a user visit a web page to authorize it. After spending time in the Browser the user should return the my application.
Currently, I'm launching the Browser with:
CODE:................
After using the browser, I can go back home and launch my application, which stacks a new Activity on top of the previous stack of Activities that were being used in the application. For example. If the user launches the app, they have Activity A in the stack. From there we navigate to Activity B which then launches the Browser. Then, the next time we enter the app, we launch Activity A, which is pushed onto the stack that already contains an A and B.
My question is then, how can I just go back to the previous stack? Basically, do I have to create a new Activity? Is there a better way to launch the Browser, and then come back to my application?
Also, I've been using the Intent.FLAG_ACTIVITY_NEW_TASK when I start the Browser activity so that my app stays running.
New to android..been using WM 6.1 sync with outlook obviously seemless. Need the same type of functionality but it doesn't have to be with outlook. Looking for options to use for business. Being a small company I can go anyway I want, don't have any restrictions other than need to sync all with phone, laptop and desktop. Beginning to travel more so contact, calendar and task must sync (notes and a Today front end would be nice). I have tried Dejaoffice but I end up with 2 sets of contacts and calendars (Samsung and Dejaoffice) not to mention that the UI is lame (had just as good 15 years ago with Instant Recall). Don't mind rooting the phone if needed. So what options exist in the open source world? Love my captivate phone but need to be able to do business to keep it. Anxious to hear how the rest of the Android world does it.

- Bluetooth sharing (or it stores the notes as .txt files on the SD card). Alternatively, it could sync with google in some way. If you know one that does these, please tell me. Else please tell me what app you're using, so that I can try it if I haven't already.
I have a static library that contains some JNICALL functions, i.e. they are expected to be called from the JVM and are never referenced by the shared library that links the static library. However, it seems like function stripping is exterminating the JNICALL function (it's not visible in arm-eabi-objdump -t). I'm working around it by adding a dummy function with an impossible condition that calls the JNICALL function, but that's dirty. I know that there is a link option to prevent certain modules from getting their unused data stripped, but what is it? And how do I specify that option in the .mk file? I didn't see anything immediately obvious in arm-eabi-ld. Incidentally, the function stripping doesn't strip out JNICALL functions in the shared library itself, but it will remove those from the static library that the shared library is linking. What's the reason for that?

I think this should be easy to answer. I have an application that does some long calculations, and I would like to show a progress dialog while this is done. So far I have found that I could do this with threads/handlers, but didn't work, and then I found out about the AsyncTask.In my application I use maps with markers on it, and I have implemented the onTap function to call a method that I have defined. The method creates a dialog with Yes/No buttons, and I would like to call an AsyncTask if Yes is clicked. My question is how to pass an ArrayList to the AsyncTask (and work with it there), and how to get back a new ArrayList like a result from the AsyncTask?
