from:"Nick"

I am using the Google compatibility library for Fragments.  I have a 
ListFragment that upon selection from a context menu performs a fragment 
transaction replace to display another fragment.  This operation works 
fine, however following a screen rotation the the commit operation fails 
giving the following exception:

java.lang.IllegalStateException: Can not perform this action after 
onSaveInstanceState

According to the documentation I should use commitAllowingStateLoss due to 
the onSaveInstanceState being called.  When I switch to the 
commitAllowingStateLoss call I get the following error:

java.lang.IllegalStateException: Activity has been destroyed

Note, in the ListFragment I am overriding the onAttach and storing a 
reference to the Activity which is provided following the screen rotation. 
 From the activity I call getSupportFragmentManager in order to perform the 
FragmentTransaction.  How is the activity becoming null?  Is this an issue 
with the compatibility library, or any I doing something wrong?  Thanks in 
advance.

 When I have run into this error, it is because I am calling something
 on a fragment that no longer exists (e.g., destroyed in a
 configuration change).
 
 

This makes sense, I understand the issue with calling commit, I have not 
problem switching to commitAllowingStateLoss().

  the onSaveInstanceState being called.  When I switch to the
  commitAllowingStateLoss call I get the following error:

 You should not need to do that, as you can call getActivity() from any 
 Fragment.

I was initially just calling getActivity() from the ListFragment, however that 
was returning null.  When I captured the Activity in the onAttach method I ran 
into the issue during the commitAllowingStateLoss().
 
   From the activity I call getSupportFragmentManager in order to perform the
  FragmentTransaction.  How is the activity becoming null?
  
 
 
 Based on your description here, it is not becoming null. You would
 have a NullPointerException if it were null.
 
 

I was just following the stack trace and using JD-GUI to look at the code.  
More of the stack trace looks like this:

java.lang.IllegalStateException: Activity has been destroyed
at 
android.support.v4.app.FragmentManagerImpl.enqueueAction(FragmentManager.java:1314)
at 
android.support.v4.app.BackStackRecord.commitInternal(BackStackRecord.java:541)
at 
android.support.v4.app.BackStackRecord.commitAllowingStateLoss(BackStackRecord.java:529)


JD-GUI shows inside the enqueueAction method an IllegalStateException is thrown 
when the Activity is null.  Do you have any suggestions to get around this.  
I'd really just like to be able to perform replace operations on a 
FragmentTransaction following screen rotations.  Thanks again.

Re: [android-developers] FragmentTransaction commitAllowingStateLoss problem

Hi Mark, 

I am not exactly sure what you are suggesting.  I do call 
registerForContextMenu inside the onActivityCreated() method and super, but 
nothing else.  Are you suggesting I do something there?  The invocation of the 
to perform the FragmentTransaction replace occurs from the 
onContextItemSelected.  The view has already redrawn itself well before I 
attempt to trigger the context menu following the screen rotation, but the 
commitAllowingStateLoss() still fails.  I'm open to suggestions.  Thanks.

 Then you were doing the work in too early of a lifecycle method, most
 likely. Try sliding to a slightly later one (e.g.,
 onActivityCreated()).

Re: [android-developers] FragmentTransaction commitAllowingStateLoss problem

Hi Mark, 

I am using setRetainInstance(true) with all of the Fragments.  I am actually 
new'ing up the detail fragment on the invocation of the onContextItemSelected() 
so there is no old reference hanging around.  After looking a bit further, I am 
starting to wonder if it has something to do with the context menu.  I am able 
to perform a separate Fragment Transaction replace operation during screen 
rotations triggered from the onListItemClick without issue.  Following screen 
rotation, I logged the getActivity() call in onCreateContextMenu which is still 
valid, but the onContextItemSelected shows getActivity() returning null.  Any 
thoughts as to why that might be?  Thanks.

 I am suggesting that wherever you were calling getActivity(), and it
 was returning null, was too early in the fragment lifecycle. Solving
 that would eliminate your need to hold onto the Activity separately
 yourself, and it might clear up other problems that you are
 encountering.
 
   The invocation of
  the to perform the FragmentTransaction replace occurs from the
  onContextItemSelected.
  
 
 
 Where are you getting the Fragment from that you are passing to
 replace()? If it not one that you instantiated just now, it may be
 that you are trying use a fragment that has been destroyed due to the
 configuration change.
 
 BTW, are you using setRetainInstance(true) with your fragments? If
 not, bear in mind that the fragments are destroyed and recreated
 during the configuration change, when the activity is destroyed and
 recreated.

Re: [android-developers] FragmentTransaction commitAllowingStateLoss problem

Hi Mark, 

I am invoking the context menu selection from the ListFragment, which is the 
first fragment, not the new'ed up fragment.  On the selection of the menu item 
from the context menu I want to perform the fragment transaction, which is 
failing following the screen rotation.  Any ideas why the call to getActivity() 
would fail at that point, the lifecycle should have completed at that point, 
correct?  Thanks.

 On which fragment is getActivity() returning null? The ListFragment(?)
 on which you have the context menu, or the newly instantiated one? If
 it's the newly-instantiated one, that's not especially surprising, as
 it will not go through any of its lifecycle methods until the
 FragmentTransaction gets commit()'d and processing begins on it
 shortly thereafter.

[android-developers] Adding custom enum states to an ImageButton

2012-01-20 Thread Nick

I have searched around and I found good examples on adding custom
boolean states to a drawable but I am having issues adding a state
that is a list of enums.  I am sure most of my problems lie within the
onCreateDrawableState call so I have a few questions.

1) Is the extraSpace param to onCreateDrawableState the number of
additional int[] that I would like to add or the size of the int[]? So
since I am just adding MODE I should just be increasing extraSpace by
1 and not by MODE.length?
2) I don't quite understand the mergeDrawableStates method.  If I put
it in an IF statement I am getting what I expect, but I think I am
just getting lucky.  I don't feel my IF check is correct.  My initial
assumption was that I don't do a check and always call
mergeDrawableStates but then the drawable never changes.  I have seen
where if the extra state is a boolean then the if statement checks for
that.  I don't quite know what to do about an enum.
3) When I do get it working, my ic_button_a is drawn correctly.
However every time when ic_button_c is getting drawn, ic_button_c is
resized and stretch to fit the View which includes a background
graphic that is larger than ic_button_c.  ic_button_a and ic_button_a
are the same size.

I have my custom view:
com.pkg.CustomView
android:background=@drawable/ic_button_bg
android:src=@drawable/ic_button
android:layout_height=wrap_content
android:layout_width=wrap_content/

which extends ImageButton.:
public class CustomView extends ImageButton {

private static final int[] MODE = {R.attr.mode};
private int mMode = 1;

@Override
public int[] onCreateDrawableState(int extraSpace) {
final int[] drawableState =
super.onCreateDrawableState(extraSpace + 1);
if (mMode != 0) {
mergeDrawableStates(drawableState, MODE);
}
return drawableState;
}

public void setMode(int mode) {
mMode = mode;
refreshDrawableState();
}
}

I am defining my modes here:
resources
declare-styleable name=CaptureButton
attr name=mode
enum name=a  value=0 /
enum name=b  value=1 /
enum name=c  value=2 /
enum name=d  value=3 /
enum name=e  value=4 /
enum name=f   value=5 /
enum name=g  value=6 /
enum name=h  value=7 /
/attr
/declare-styleable
/resources

My @drawable/ic_button is:
selector xmlns:android=http://schemas.android.com/apk/res/android;
xmlns:app=http://schemas.android.com/apk/res/com.pkg;
item app:mode=c  android:drawable=@drawable/ic_button_c /

item android:drawable=@drawable/ic_button_a /
/selector

[android-developers] Bluetooth Sniff idle timeout in Bluez stack.

2011-11-03 Thread Nick

Folks,

With Bluez stack running on my phone, and a PC dongle (supporting HFP/
A2DP), i am seeing a problem. Bluetooth SOC on the phone is not going
in Sniff mode, as a result the power drained is very high. This is
only when a PC dongle is bonded to the phone. If a A2DP headset is
bonded, it enters in sniff mode properly.

I also saw that the sniff idle timeout interval in case of dongle is
seen to be 0. Because of which hci_conn_enter_active_mode() is not
seting the idle timer, as a result hci_conn_enter_sniff_mode() is
never executed, and the device never goes in sniff.

The idle timeout is initialized here -
In kernel/net/bluetooth/hci_core.c, i see
hdev-idle_timeout = 0;

But this is not the correct place to modify the timeout, as it affects
all devices ...dongles, headsets..etc.

Does any body know how to set the sniff idle timeout correctly..?

Thanks

[android-developers] Fragment visibility after transaction

2011-10-13 Thread Nick Parker

Hello,

I am using the fragment compatibility library and have a question
about fragment transactions.  I am using a third-party action bar and
two fragments in this scenario.  Each fragment updates the user
interface of the outside action bar when they are displayed.  When
displaying the first fragment, I add a button to the action bar which
when clicked performs a fragment transaction replace operation to
display the second fragment.  The second fragment updates the display
of the action bar accordingly.

The problem I am seeing is when the user presses back, or I need to
manually remove the second fragment via a popBackStack operation, I
need to be able to update the view of the newly visible initial
fragment.  At first I thought that OnBackStackChangedListener would be
the solution, however when that gets triggered during the replace
going from one fragment to another it causes the initial first
fragment to update the state of the action bar when the second
fragment is actually visible.  I tried to check for visibility within
onBackStackChanged of the first fragment, but the fragment always
comes back as being visible even when it shouldn't in the scenario of
loading the new fragment.  Does anyone have any suggestions for this
type of situation?  Any thoughts to what I might be missing?  Thanks!

 Hello,
 I am looking for a Android GUI for cheap, rapid solution for

 Keep it as simple as possible for the time being.

you'll probably have to show the content on a webview on your own app if you

esa manera tenés más flexibilidad para configurarlo.

[android-developers] Prototype App Creation

2011-09-15 Thread Nick Cunningham

I'm looking to create a prototype of a product I've had in mind. In
order to do this I need an app that can read an NFC chip and scan a QR
code, then search some sort of database matching a serial number on
the chip and the QR code to some more information. I really have no
experience developing an app or even coding for that matter, just
tinkered with app inventor once or twice. Would anyone like to lead me
in the right direction or help me out with creating this app? Any help
I could get would be greatly appreciated.

 These are typically OutOfMemory errors (not exceptions) which you can

In general you can't do that. If you have an OutOfMemoryError the JVM can't
allocate more memory and then you can't show a message or something because
there is no memory to build the objects.

Each time you concatenate two strings a third one is created to hold the
result. Strings are inmutables and expensive. Try with the
StringBuffer/StringBuilder and check the results. Your code will be faster
and more legible.

 1) Is it possible for instance A to be referenced even after

Yes, because the instance is still loaded and the service holds a reference

  2) Is there a way to immediately invoke the garbage collector to clear
 out the memory space instance A is occupying?


You can call System.gc(), but that is just a hint, th GC may not run.


  3) Is this a problem with the third party service?  In my code i
 perform bind in onCreate and unbind in onDestroy... I am stumped as to
 why my destroyed instance A is still being referenced when the service

It looks like that, check with the service provider.

Also you can

In both cases you meed to pass an instance of your object with, at least,

Re: [android-developers] Re: what are the best practices for good coding skills and classes, methods, and variables naming +android

On Aug 25, 2011 6:48 PM, Indicator Veritatis mej1...@yahoo.com wrote:

That is much too vague an answer. A less vague and more helpful answer
would be, start with what is best practices for good coding skills
and classes in Java itself, and apply the same principles to
Android's classes.

Now to get that start, there is no better place to start than Joshua
Block's Effective Java, described on Amazon at

http://www.amazon.com/s/ref=nb_sb_ss_i_0_12?url=search-alias%3Dstripbooksfield-keywords=joshua+bloch+effective+javax=0y=0sprefix=joshua+bloch
.

The book from Robert Martin, clean code, it's also a very good reading.

The price on the Kindle edition is quite reasonable, though you might
want to try local libraries first: Alameda County Library has it
available for on-line reading, for example. Your local libraries might
have it too.

Next, one has to consider the issues of best practices for good
coding skills and classes that are unique to Android. This is not as
straightforward, since there is not enough clear precedent, there is
still quite a bit of controversy. Unfortunately, I cannot recommend
Google's own code practices without reservation. They too cut corners
at times, writing code that does not conform to best practices. Yet at
the same time, we are often quite dependent on them for initial sample
code. So sometimes we can recognize their practices as good and follow
them, sometimes we cannot.

+1 to that. A lot of common sense it's a good practice too.

There is also the O'Reilly Press Android Cookbook, but that is still
a work in progress.

The files are on a FTP server or on a HTTP server?

If the server is an FTP server you can connect to the server, list the files
using some API, then show the files in a listView or something like that and
download it with the same API. You don't need a browser at all.

android:textColor=#ff00
android:id=@+id/request_title
android:layout_height=wrap_content
android:lines=1 android:singleLine=true
android:layout_width=wrap_content
/TextView
/LinearLayout

!-- its this second LinearLayout that I want to be
able to touch and have it show Orange, so the user knows it was
selected --

Re: [android-developers] Why does Long.decode fail?

 I am trying to convert a string of 16 hex digits to a 64-bit Long, but
 there is a run-time exception for negative values:

Long a = Long.decode(0x3774d56d682e549c); //..works just fine

Long a = Long.decode(0x9774d56d682e549c); //..crashes with a run-
 time exception

 Apparently you can't decode a hex string that is negative as a 64-bit
 Long.  Why?
