[android-developers] Re: AsyncTask null exception for the activity reference in the doInBackground method while rotating.
doInBackground like you have it is not the way to do that -- what you
have coded is called spinning
Kostya Vasilyev's explanation is clearer than mine and will move you
in the direction of correct code if you take the suggestion and
continue to work it but rather than doing a spin-lock as a wait we use
instead a programming approach known as interfaces - sometimes called
callbacks - which will be in the AsyncTask documents
rather than detaching what you do is call dot start on AsyncTask (a
form of Threading) and let it run
If it ( the program ) has to callback to the User Interface then use
of AsyncTask needs to have the UI element in it that the UI thread
will call into
If background thread does not need UI to then dont really need
AsyncTask but need a service or something instead
you can pass object references to some forms of background processing
which then can set a var in the AsyncTask based class from background
processing or there are callbacks / interfaces in some supplied
classes that are meant for that

the guy talks fast by most people but seems rather simple to me -- you
fix this stuff now or get blown off the sidewalk later by an NPE when
IntentService.onBind (Intent intent) default implementation returns
null but you decided not to implement android:maxSdkVersion
to do this work you have to keep clear in your mind that a Thread
( from wherever it came ) is an instruction pointer in whatever is
driving the code ( which usually is a processor ) then the whole thing
becomes remarkably simple
surprisingly for those who have not bit the dust on it several times
one can do an amazing amount just by making all method calls
synchronized or using synchronizaton blocks -- you will see in most
accomplished code a style of code design Object lock = new Object()
and you just barrier on that

in this case the activity(UI thread) calls the detach method like you said,

[android-developers] Multiple layouts
Hi, I'm trying to add support for a layout for the Samsung Galaxy Tab 7 device. I can't seem to find a way to specify a layout config that it will pull the layout xml from. It keeps using the resource from the Normal screen/High Density folder, which makes sense, but the layout is small and centered in the middle of the screen. I was hoping to use the newer layout-sw600dpi folder config, but it never pulls from the folder. I've set my min api to 4 and target api to 14. Does the Support Library offer a backward compatible means to use the newer qualifiers in 3.2 in older api's? (I'm hoping this is the solution!) Is there a way to code my app to identity a devices resolution and direct the system to use a particle layout? Will using Fragments in anyway help with older apis? I know that there is a huge debate about resolutions and densities and I should create a layout that hard codes sizes, but that is what my app requires. I've done everything I can to keep it resolution independent and have created several layout to address a range to display sizes, but the Samsung 7 device falls through the cracks. I've search everywhere I could find and have read and reread to sdk docs, but I haven't found an answer. Any help would be appreciated.

Re: [android-developers] Multiple layouts
Assuming you mean the original Galaxy Tab P1000. According to Samsung, it is a -large device, so using res/layout-large, or perhaps values-large/dimen.xml should work. Those new resource qualifiers are new with 3.2, and it's a runtime version requirement. Layouts scaled to a portion of the screen and centered sounds like compatibility mode.

Re: [android-developers] AsyncTask null exception for the activity reference in the doInBackground method while rotating.
Thanks guys. The idea was to call a unique class whenever an activity had
the need to launch tasks, but since i have parent activity where all the
activities extend from, they would call the async task and each one would
have a method that would used in the doinbackground method of said async
task. Right now im using no reference to the activity in the doinbackground
but because of this im extending the asynctask class i've created to
acomodate the different needs to the different activities, but i thought it
would be more direct if i had the logic to run in the async tasks right in
the activities

On Sat, Nov 19, 2011 at 1:19 PM, Kostya Vasilyev kmans...@gmail.com wrote:
Hi,
The original code that you posted did contain concurrent (multithreaded)
reads and writes of the activity member variable. That concurrency was
causing null pointed exceptions in a *seemingly* impossible place. The
reason, as far as I can tell, you had concurrent access to the member
variable was that you wanted to delegate the actual background work to the
activity, while keeping your async task implementation generic and unaware
of the exact nature of background work.
So, with this in mind, I can see two ways of fixing things:
1) Keeping your way of structuring the code, and adding proper thread
synchronization.
Here is one way:
void detach() {
synchronized(this) {
this.activity = null
}
}
... elsewhere (IIRC)...
void the_method_where_you_were_getting_a_null_pointer_exception() {
MyActivityClass checkedActivity;
synchronized(this) {
checkedActivity = this.activity;
}
if (checkedActivity != null) {
.
}
}
There are other things to be careful with here, for example, the activity
may be paused, stopped, or its onDestroy called (on the UI thread) while
the async task's thread is still in its worker method. Accesses to member
variables of activity would also need to be synchronized, or preferably
avoided So don't undertake this unless you've learned at least the
basics of concurrent programming.
2) Restructuring the code in a more orthodox way, as described in the
docs and was already suggested on this thread by Streets of Boston and
TreKing (IIRC).
Have your AsyncTask perform the work without delegating to the activity,
and only reference the activity (if any) on the UI thread, in
onPostExecute. This way you'll be avoiding concurrent reads/writes of the
activity member variable, because onPostExecute and detach are both
executed on the UI thread.
Hope this helps.

Re: [android-developers] AsyncTask null exception for the activity reference in the doInBackground method while rotating.
So in my Async Task class doInBackground and detach methods i could use :
@Override
protected Object *doInBackground*(Void... params) {
MyActivityClass *checkedActivity*;
synchronized(this) {
*checkedActivity *= this.activity;
}
if(*checkedActivity*!=null){
Logger.write(QuadrosMobileActivityTask , AsyncTask background
initialized +Current Activity: +checkedActivity .getClass().getName(),
Logger.INFO);
return *checkedActivity *.doBackGroundRequest();
}else{
Logger.write(QuadrosMobileActivityTask , AsyncTask finished while no
Activity was attached., Logger.INFO);
return null;}
}
and the detach method would change to:
void *detach*() {
synchronized(this) {
this.activity = null
}
}
Still i need to study this morethanks the same to both

Thanks guys. The idea was to call a unique class whenever an activity had
the need to launch tasks, but since i have parent activity where all the
activities extend from, they would call the async task and each one would
have a method that would used in the doinbackground method of said async
task. Right now im using no reference to the activity in the doinbackground
but because of this im extending the asynctask class i've created to
acomodate the different needs to the different activities, but i thought it
would be more direct if i had the logic to run in the async tasks right in
the activities

Hi,
The original code that you posted did contain concurrent (multithreaded)
reads and writes of the activity member variable. That concurrency was
causing null pointed exceptions in a *seemingly* impossible place. The
reason, as far as I can tell, you had concurrent access to the member
variable was that you wanted to delegate the actual background work to the
activity, while keeping your async task implementation generic and unaware
of the exact nature of background work.
So, with this in mind, I can see two ways of fixing things:
1) Keeping your way of structuring the code, and adding proper thread
synchronization.
Here is one way:
void detach() {
synchronized(this) {
this.activity = null
}
}
... elsewhere (IIRC)...
void the_method_where_you_were_getting_a_null_pointer_exception() {
MyActivityClass checkedActivity;
synchronized(this) {
checkedActivity = this.activity;
}
if (checkedActivity != null) {
.
}
}
There are other things to be careful with here, for example, the activity
may be paused, stopped, or its onDestroy called (on the UI thread) while
the async task's thread is still in its worker method. Accesses to member
variables of activity would also need to be synchronized, or preferably
avoided So don't undertake this unless you've learned at least the
basics of concurrent programming.
2) Restructuring the code in a more orthodox way, as described in the
docs and was already suggested on this thread by Streets of Boston and
TreKing (IIRC).
Have your AsyncTask perform the work without delegating to the activity,
and only reference the activity (if any) on the UI thread, in
onPostExecute. This way you'll be avoiding concurrent reads/writes of the
activity member variable, because onPostExecute and detach are both
executed on the UI thread.
Hope this helps.

Hi there! Sorry for posting here again, but i was hoping if i could try
this sample, you said to put the synchronized in the detach method here:
void detach() {
*activity=null;*
}
in the asynctask, is this correct?but detach() is only called in the
activity and not the in the async task itself, i thought synchronized
methods assumed that they're both launched from 2 different threadsbut
in this case the activity(UI thread) calls the detach method like you said,
but the async task doesnt, only the attach method...

Hi,
I actually tried this: I set up a KindleFire AVD with Camera
support=no.
I am doing experiment:
--
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.menu, menu);
PackageManager packageManager = getPackageManager();
hasCamera =
packageManager.hasSystemFeature(PackageManager.FEATURE_CAMERA);
Log.d(Kids Paint, has camera: + hasCamera);
return true;
}
--
But the answer is has camera: true.

[android-developers] Lots of the layout ID xyz is not valid errors in ADT r15
So, having upgraded to ADT r15 I am now getting scores of these errors in the layout editor. Let me emphasize that it used to work fine before (that is, in r13), that the compilation is clean and the app runs just fine: it's only when you try to open a layout in the layout editor that you get these errors; in short they are 100% spurious. They are rampant: pretty much every layout with an include triggers one, and ineradicable: no amount of re-building, cleaning or even deleting and re-creating the project will make them go away. What happened? This is a very big deal as it makes the layout editor all but useless and that was the single most valuable bit of the ADT (for me at any rate). -- O.L. -- You received this message because you are subscribed to the Google Groups Android Developers group.

FWIW, I have never seen that error. Moreover, if everyone were seeing those errors, we'd've heard about them by now.

Re: [android-developers] AsyncTask null exception for the activity reference in the doInBackground method while rotating.
This will work if you just want to get rid of the null pointer exceptions. However, you just should never do any background work in an activity, i.e. run code in an Activity on the stack of a background thread (in your case, calling Activity.doBackgroundRequest()). It will set you up for problems. It is unlikely, but not impossible, that the UI thread kicks in after a phone rotation, between the assignment of checkedActivity and the execution of checkedActivity.doBackgroundRequest(), and calls the onDestroy of the activity. How would that behave for your app? The proper way of doing this is to execute code in the background that does *not* require an activity (or any UI type of object) to be accessed. If this background processing yields a result that needs to be communicated to the screen (Activity/View/etc), then you'll implement onPostExecute to do so. *Refactor *your code do move the code in 'doBackgroundRequest' out of your activity and put it into your subclass of AsyncTask instead. If you need pieces of data from your activity, assign just those pieces to the new QuadrosMobileActivityTask object when you construct it. If you access your activity in the construction of the AsyncTask and in the onPreExecute and onPostExecute only, you no longer need to use 'synchronized' blocks anymore... all access is done on one thread (the main UI thread) only. -- You received this message because you are subscribed to the Google Groups Android Developers group.

Re: [android-developers] Layout Question
I would think that changing the layout_height of the LinearLayout to wrap_content would help. With what you have, both children of the RelativeLayout are set to fill_parent, so they'll have the same height. Also, I would recommend you make up your mind whether you're going to use fill_parent or match_parent. It's annoying to use both of them. -- You received this message because you are subscribed to the Google Groups Android Developers group.

Yes, this has been discussed extensively. You cannot use a Google account for syncing calendars on the emulator. You can use an Exchange account, though, with a gmail address and a blank domain.

I can no longer get any avds to launch. I can create them, but they will not start (from targets 2.2 up to 4.0) I am running Windows XP and have the latest updates for eclipse and android addons. Problems occurred after updates for both eclipse and android were installed 3 weeks ago (approx Oct 26th, 2011) Now I cannot get avds to load. I have installed and uninstalled the avds. I have run the emulator from the command line. I have re-installed sdk tools 15 I have installed latest android and eclipse updates today (Nov21st, 2011) All to no avail. The error is ALWAYS the same and the debugger ALWAYS flags the SAME offset (see below). I have looked through, and tried, all the 'helps' that I can find including no snapshot, different resolutions, etc, etc, etc. I would have hoped the latest updates would fix it - - but I have now been without an avd for more than 3 weeks and it is seriously restricting my work.

Thanks Mark. I took a look at your code, then modified it to
duplicate the situation I described: added a custom Adapter extending
BaseAdapter and implementing SectionIndexer. As you said, when I
create a new instance of the Adapter and pass it into setListAdapter()
the new instance is used. So the problem I described does not exist.
However, the problem that led to my mistaken assumption is duplicated
in your code (as I've modified it): only the first instance of my
custom Adapter ever gets its getSections() method called. So though
the new Adapter has replaced the original, the Object[] of sections
returned by the original continues to be used.
Does anybody know if there's a way to force the framework to call
getSections() when a new Adapter replaces the one that was called
originally?
I've worked around this problem by creating a new ListActivity
instance each time my data set changes. It's a bit heavy handed but
does the trick.
Thanks,

[android-developers] Re: How to set WebView to follow 302 redirects
Hi, Some more additional info: When I use a URLConnection to GET the request it, works and follows the redirect properly. What I do next is to use this reponse and load the html to the web view using webView.loadDataWithBaseURL() - in here I set the baseUrl to the host I expect. I also tried to set the following: webSettings.setJavaScriptEnabled(true); webSettings.setJavaScriptCanOpenWindowsAutomatically(true); As it seems the pages I load uses javascript to change the window.location, but when this happens, it doesn't seem to go through the WebViewClient.
