Hi there! CAn you share your code for this combination? Right now im using
an async task in my parent activity to launch threads, i also have a custom
header with a progressbar(indeterminate) where my threads change its state.
Right now this seems to be working, but the problem arises when i
How do you something like this:
Heres my onCreate of the parent activity:
protected void onCreate(Bundle savedInstanceState) {
//set theme first for showing correct header
setTheme(getThemeId());
super.onCreate(savedInstanceState);
themeId=getThemeId();
//in case the screen will have a
Hi! So i've been trying to get a solution for a very specific problem that
involves using Async tasks and dealing with the rotation and also a custom
header that contains a progressbar view(the small spinner one, including a
text view saying Loading...). I've followed
IS there a way to avoid the static references to the views, but at the same
time giving the possibility of the tasks to change the visibility of the
progressbar even if the current activity visible is not the one who laucnhed
the task initially?

Hi! im using an Async-Task and currently im using runOnUiThread in the
doInBackground method to refresh activities UI, this seems to be working but
on rotation it loses the data and im usng the
getLastNonConfigurationInstance and the onRetainNonConfigurationInstance
methods, here's the parent
The only static variable in use is an int, for maintaining the state of a
progress bar while switching activities. the updateResultsinUi() is an
abstract method tha is implemented by sub activties classes.

So im using an AsyncTask but i'm getting random null exceptions for the
activity reference in the doInBackground method. Anyway here's the non
inner public async task:
public class QuadrosMobileActivityTask extends AsyncTaskVoid, Void,
Object{
*protected QuadrosMobileActivity activity=null;*
No one?

For more options,
yes the detach is called on the activity thread in the
onReatainNonConfigurationInstance method...:
*@Override*
* public Object onRetainNonConfigurationInstance() {*
* if(task!=null)*
* task.detach();*
*
*
* return(task);*
* }*
And here's the method that attachs the activity back to the
Well the thing is, this Asynctask is binded to a parent activity, that the
subactivities use when they want to do some background work. They each
implement the method you see in the code i've posted, the *
activity.doBackGroundRequest(); *
I've actually had errors even after the line
Also wouldnt using the activity.getApplicationContext() result in the same
problem??? if activity is null i would stil lget the null exception???

yes, but how can i get the method from the activity that contains the logic
to do in the background from the context, is this possible? im getting null
exception for the activity after verifying if the activity is not null:
if(activity!=null){
return
How so? each activity launches its own async task with its own specific
logicwhen you rotate you just detach the current activity from the
async task, the activity gets destroyed, a new one is created and attached
to the SAME async task

Hi again skyler, thanks for the reply, yes the code im using in the
doInBackground deals with the logic i want to do in the background that
each activity has, in this case the method doBackgroundRequest is the
method every activity uses if it wants to use an async task...but it seems
this
What about extending the async task and then implement the logic directly
in the doInbackground method?

Yes i have a indeterminate progressBar in the header, the spinner one, but
im using broadcast to all the activities which have the spinner to show or
hide it if there's a task running in the background :

Hi there! Yes i removed the code from activity.doBackgroundRequest to the
extending Async Tasks doInBackground, i think it might solve this, BUT i
will se the thread synchronization topic.
Thanks for the attention.

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

Hi! im currently using an expandable list as an n-tree level list, and i
use the long click to select any element, either group or childs, the
problem is that the group row has a gradient gradient backgroup so
translates in it not having any kind of highlight. i managed the normal
click color,
Basically what i want is default behaviour in all states but with my own
backgroud gradient:S

states, your drawable will turn transparent and let the android list item

You'll also need android:duplicateParentState on the layout added in step

Hi! So im currently trying to make my custom dialogs persistent after
rotation and i was going to use the onCreateDialog method for that. but it
seems to be deprecated and instead i was pointed to the DialogFragment
class.
I've seen some tutorials in android developer page and my main question
So i was having this error after some rotations were made. After this i
used the onDestroy method do get rid of drawables:
@Override
protected void onDestroy() {
super.onDestroy();
*unbindDrawables*(findViewById(android.R.id.content).getRootView());
System.gc();
Runtime.getRuntime().gc();
}
