Re: [android-developers] Fragments won't display in port orientation
Aren't you also supposed to specify the orientation of the fragment as well ...so the xml definition is fine but i think u should look at the fragment definition as well. On 17 Apr 2011 09:42, Brill Pappin bpap...@sixgreen.com wrote: I'm very confused on why my fragments refuse to draw in portrait mode and draw fine in landscape mode. I'm build a screen with two fragments. in landscape they are side-by-side and in portrait they are supposed to stack one above the other. however now matter what I seem to try, the portrait mode refuses to draw the fragments. I can also not use any layout except LinearLayout and even then if I add the LinearLayout android:orientation=vertical the fragments refuse to draw. I'd actually prefer to use the RelativeLayout in this case, but i does not display anything at all. To illustrate what i'm doing: This works... ?xml version=1.0 encoding=utf-8?

I've been hacking away at this for a while now, trying all sorts or permutations and layouts with no luck. Does anyone have any suggestions on what i might try, or even how to debug this, that i may not have tried already?

Re: [android-developers] Database shared by Activity and Service. What's the best approach?
Would a content provider work? On 14 Apr 2011 04:56, bogde bogde...@gmail.com wrote: I'm new here and new to Android development too, so I want to apologize for my ignorance. I'm working on an application that is supposed to gather some data from an external device continuously, display the data on a chart in real-time and also store data so it's accessible at a later time as a table or as a chart. The application needs to store the data all the time, even if it's not active on the screen. Currently I have a service that starts on boot and deals with receiving the data and storing it inside a sqlite database. The service opens the database and keeps it open all the time, until it's killed. This part seems to work pretty well so far. Now, I would like to have an activity that retrieves the last 60 values from the database and plots them on a chart. I'm currently using Android Plot. I need to have a thread or something that constantly checks for database changes and redraws the chart on the screen if needed. My question is, what would be the best way to accomplish this? How to share the database between the service that runs all the time and an activity? I searched and answers to somewhat similar questions are all over the web. However, most people talk about how to share the database between two or more activities or between an activity and a service that is started temporarily.

Re: [android-developers] static variable set to null
your code force closing is preventable by a simple null check..
if(yourvariable != null){ do something}else{do something else or do nothing
and display an error message}. The question about whether youwant to share
global variable between
activities is something you should really ask yourself... pass stuff to
other activities using intents or bundle and do null checks. that way you
can find out which activities are settting ur data to null and fix it..

hello everybody,
I use a static variable to share data across all the activities of my
apps.
The problems is that sometimes this variable is set to null, which
cause the others activities to crash (nullPointersException) ...
does somebody have an idea of what could set the static variables to
null ?
regards,
Christophe

new Thread() {

at least it work fine in the emulator, but i'm concerned about it's
correctness, specifically about calling prgDialog.dismiss(); (note
that the variable prgDialog is created in the main thread), is this
correct?

Re: [android-developers] Problem with ListAdapters and Cursors
