If you're on API 11 and higher, you can use this to be notified when the 
user submits a query:

For previous API levels, you may be able to use a singleTop activity and 
override its onNewIntent.

Re: [android-developers] AlphabetIndexer with Custom Adapter managed by LoaderManager


How does it error out? A crash? What's the stack trace?

In general, the fast section indexer does not update its sections list 
automatically when you replace the cursor. There is no method to force 
this except turn it off and the back on after you've changed the data.

Which is a CheckedTextView -- you can examine the copy of this layout

 I also came across checkedTextView, but I couldn't

At the end of the day, so long as your row View implements the

Re: [android-developers] Re: How to get accurate time stamps from Android GPS location.

2012-04-25 Thread StarTraX

I've been reading up on the GPS signal structure, and it's true that it 
takes 12 1/2 minutes for the full sequence, but... and this is a big but... 
the GPS time and GPS/UTC offset are sent with every sub frame, and they 
come by every six seconds. 
So you can forget about waiting 12 1/2 minutes. before being certain of the 
time! It's synchronized every 6 seconds. Its all well explained 
in Wikipedia http://en.wikipedia.org/wiki/GPS_signals

 it would report exactly UTC, i.e. after reception of the GPS/UTC correction

 Since then a UTC leap second had been added.

 Importantly, there is no way to tell which of those times the GPS is

 For my project I was using a SiRF III receiver and could switch on the raw

 AFAIK, there is no way of doing that on Android, so for truly accurate

[android-developers] Contact UI Question

2012-04-25 Thread Mark Phillips

In my application, I need to collect information about (most likely) new
people for the phone's contact database (eg players on a sports team). I
see how to add the information using the Contacts API (
http://developer.android.com/resources/articles/contacts.html). I was
thinking of adding the contact with a new group name, so I can easily find
them again and display just those the names in a ListActivity.

What about the ui for creating and editing contacts? Do I have to create my
own contact editing ui, or is there a way to drop the user in the native
edit contact ui to enter the information about the contact, and then bring
them back to my app's ui when they are done?

Thanks,

Mark

 Unless I'm not understanding your requirement, that is EXACTLY how
 SlidingDrawer works...

 Here is the sample XML file on the SlidingDrawer docs...

  SlidingDrawer
  android:id=@+id/drawer


  android:layout_width=match_parent
  android:layout_height=match_parent


  android:handle=@+id/handle
  android:content=@+id/content


  ImageView
  android:id=@id/handle

  android:layout_height=44dip /


  GridView
  android:id=@id/content


  android:layout_width=match_parent
  android:layout_height=match_parent /


  /SlidingDrawer

 The content is hidden... The handle is always visible.  And the handle can
 be any layout, just as you wanted.  And when you click that handle, it will
 come out as a drawer, just like you want.

[android-developers] Total Available memory for Memory Management logic.

2012-04-25 Thread Anieeh

Hi all
I am having problem with releasing memory problem, i have a
Hashmap in which i am adding Bitmap object, and the no. of bitmaps are
quite large. for this reason i am getting OutOfMemoryError. So for
this i have decided to release Bitmap whic is least used from
Collection, on memory crunch or system getting low heap memory.
  For getting current memory available i used
ActivityManager.MemoryInfo.availMem but it gives total RAM size
memory, not Available Heap memory. And i found that this memory is not
getting updated on releasing  Bitmap from collection.

Then i have used these three method
Debug.getNativeHeapAllocatedSize()
Debug.getNativeHeapFreeSize()
Debug.getNativeHeapSize()

but found the NativeHeapSize goes on increasing upto some certain say
16MB changing after that an outOfMemoryError occur. In this also i
found that the NativeHeapAllocatedSize and getNativeHeapSize not
decreasing on releasing  Bitmap from collection.

So please help me for solving the problem if anyone facing the same
problem and fixed earlier it.

My problem is i want to calculate Max Available application memory
allocated and currently available memory, for such that if
currently available memory goes beyond the Threshold memory i will
release some Bitmap from the collection and GC will reclaim the memory
and free it without generating error.

Thanks in advance

Check it out, Romain gave some good explanations there.

If you'd just like to free some memory on out-of-memory condition you
shouldn't need exact numbers (those are hard to get as explained in
the linked topic). Why don't you just catch OutOfMemoryError and
handle it by freeing your least recently used bitmaps, then perhaps
restart the operation that caused the fault? Do you need an early
warning (even before you actually run out of heap) for some reason?

 s...s...st...t...ah...ar...rr...rrt..tti...ining). Given that the 
 unmodified ApiDemos/OS/Sensors.java runs smoothly on OS 4.0.4, I suspect 
 the decrease in sampling speed is related to some change in the OS's 
 efficiency of writing to the SD card.

 Has anyone else noticed problems related to SD card write speed after 
 updating to OS 4.0.4 (Ice Cream Sandwich)? If I don't hear from anyone, 
 I'll try to isolate the problem with a simpler application and file a bug 
 report.

[android-developers] BitmapFactory.Options inTempStorage

2012-04-25 Thread Jim Graham

While working on trying to squeeze in as much space for processing
bitmaps in my app, I noticed this method, and from what I've read,
believe it might help.  What I have not found, however, is a real (and
clear) description of what it does, and how to best use it.

The dev guide page suggests using it to create about 15 kB of temp
space.  Examples I've seen from this list in the past suggest the
same, even for as much as 9 MB bitmaps.  15 kB temp space for 9 MB
bitmaps makes no sense to me, so I'm clearly missing something.

Can someone please either explain it, or point me to a page that
does?

Thanks,

I don't know for sure, but I would assume that is because it doesn't decode
the entire 9 MB image at once...

[android-developers] Re: Total Available memory for Memory Management logic.

2012-04-25 Thread Anieeh


Thanks Latimerius
   For your quick reply, yes i need an early warning (even before you

because after an error occur OutOfMemory and then if i release some
memory and restart the
same operation it will give the same error since the GC wont collect
the free memory as soon as
we released some bitmap memory. And the same will happen over and
over, and it increase the
overhead of re-Starting the same task.

 If you'd just like to free some memory on out-of-memory condition you
 shouldn't need exact numbers (those are hard to get as explained in
 the linked topic).  Why don't you just catch OutOfMemoryError and
 handle it by freeing your least recently used bitmaps, then perhaps
 restart the operation that caused the fault?  Do you need an early
 warning (even before you actually run out of heap) for some reason?

   For getting current memory available i used
  ActivityManager.MemoryInfo.availMem but it gives total RAM size

  Then i have used these three method
  Debug.getNativeHeapAllocatedSize()
  Debug.getNativeHeapFreeSize()
  Debug.getNativeHeapSize()

  but found the NativeHeapSize goes on increasing upto some certain say
  16MB changing after that an outOfMemoryError occur. In this also i
  found that the NativeHeapAllocatedSize and getNativeHeapSize not
  decreasing on releasing  Bitmap from collection.

  So please help me for solving the problem if anyone facing the same

  My problem is i want to calculate Max Available application memory
  allocated and currently available memory, for such that if
  currently available memory goes beyond the Threshold memory i will
  release some Bitmap from the collection and GC will reclaim the memory
  and free it without generating error.

[android-developers] Re: ndk, shared library's global variables persist

2012-04-25 Thread Chris Stratton

On Tuesday, April 17, 2012 11:59:42 AM UTC-4, Anatoliy Lysenko wrote:

 Hi, 
 In my NDK project I have two global variables, int and pointer. 

 When I install my app and run it for first time, all global variables

 When I exit app and start it again, in both variables stored values 
 from previous run. 


This is actually not strictly an NDK issue, rather then NDK is making a 
universal aspect of Android apps a bit more easy to see.

On an ordinary system, programmers think in terms of a process.  These 
exist on android too, but there is not a 1-1 correspondence with 
activities.  Even when all activities and services hosted by a process 
entirely finish, android will try to keep the process around for a faster 
restart of that app, killing it off only if the system becomes memory 
constrained.  In the ordinary case, when a user re-enters a recent 
activity, it runs in the old process that is still around from the last 
time.  But that is of course not always the case - sometimes the old 
process has been reaped (or it has crashed, or was never previously run) 
and a new one must be created.

The NDK is not unique in having certain things that can survive with the 
process, irrespective of the component activities or services - that can 
happen with the java code too.  However, appropriate practices for handling 
this for ndk code might indeed be better on the ndk group.

Re: [android-developers] getInstalledPackages(PackageManager.GET_ACTIVITIES) - PackageManager has died!?

2012-04-25 Thread 3c

Well, I reverted the call to getInstalledPackages(0);

Then manually retrieved the activity I was interested in, as I knew in 
advance which one to look for.

A flawed firmware why not, but just exceeding 1MB of activity data seems 
unreasonable? My kids have installed 300+ games on their tablets and 
there's still like 70% free space! Though not such issue on those tablets. 
So 1MB of activity data would mean how many apps installed, any rough idea?

Thanks for your prompt reply.

Beats me. I have never tried counting bytes of getInstalledPackages()
output. The 1MB limit is a known barrier on IPC transactions.

I see - makes sense I guess.  What if you ran System.gc() after you
release some bitmaps?  I know it makes no guarantees and using it is
generally frowned upon, but I would probably at least give it a try.
I suspect none of the ways you could possibly handle this will be very
solid, it's mostly more or less dodgy techniques as far as I know.
The very presence of a GC makes it rather hard to tell how much memory
is left.

Depending on your situation I'd probably still stick with my earlier
suggestion.  Make your operations explicit in your program (package
them up in classes behind an interface like Runnable) and queue them.
Iterate through the queue running the operations and catching
OutOfMemoryError.  If it occurs free some bitmaps and perhaps try
running System.gc() afterwards.  Leave the operation that threw in the
queue.  Repeat until no more OutOfMemoryError.

I can imagine a lot of unwelcome corner cases that would complicate
the scenario, however this way at least you get the restarting pretty
much for free.

RE: [android-developers] getInstalledPackages(PackageManager.GET_ACTIVITIES) - PackageManager has died!?

2012-04-25 Thread Cedric Counotte

Why am I doing what ? getInstalledPackages(0), because I'm interested in
specific package names with a predefined prefix, those may include a
specific activity to configure the package.

 

All the packages I'm looking for are app extension that I develop myself. So
using getIntentActivities() is of no interest in this situation.

 

In other words I'm searching for packages with predefined named (eg
prefix.name) and then out of those I need to know which one have an
activity named settings.

 

Now the getInstalledPackages(PackageManager.GET_ACTIVITIES) is a valid API
call, and nothing in the documentation says not to use it, but nevertheless
it doesn't seem to be a good idea.

 

Some users got FCs while others didn't get any results out of it.

One or both of the function calls (getWritableDatabase etc) throws the

Re: [android-developers] newbie SQL Light Question

2012-04-25 Thread A. Elk

It's an abstraction, to be sure, but it also protects you from malicious
SQL injection. Forming raw SQL statements, especially from user input,
allows users to hack the sense of your statement in truly evil ways.

Using query() avoids this. All of the parameters of the query are passed in
as arguments. No strings are concatenated, and no statement compilation is
done. There's no way for the user to inject malicious SQL.

Notice the ContentResolver.query() method. It has both a selection and
selectionArgs parameter. To be safe, use the selection argument for
column names and operators, and put the values to compare to in
selectionArgs. The values are inserted into the selection clause
without concatenation, so no SQL injection can occur.

Nonsense. Heck, I'll even throw in balderdash.

On SQLiteDatabase, query() eventually calls queryWithFactory(), which
creates the full SQL statement via
SQLiteQueryBuilder.buildQueryString()... which does concatenation.

[android-developers] Re: Contact UI Question

2012-04-25 Thread A. Elk

You don't have to create your own contact editing UI. You can send an 
intent to the contacts app, which will bring the app to the foreground, 
displaying the Add Contacts screen. You can send extras that will populate 
the screen with data. See the javadoc for ContactsContract.Intents.Insert. 
If you send the intent with startActivityForResult(), you'll get a callback 
to onActivityResult(), which has an intent argument. The data field for the 
intent contains a content URI for the newly-added contact.

  While working on trying to squeeze in as much space for processing

  clear) description of what it does, and how to best use it.
 
  The dev guide page suggests using it to create about 15 kB of temp
  space.  Examples I've seen from this list in the past suggest the
  same, even for as much as 9 MB bitmaps.  15 kB temp space for 9 MB
  bitmaps makes no sense to me, so I'm clearly missing something.

 I don't know for sure, but I would assume that is because it doesn't decode
 the entire 9 MB image at once...

Ok, I could assume that as well (and I more or less did).  But I prefer
actual documentation over assumptions.  And that was only one part of my
question.  Every post I read where this was used involved using it to
avoid out of memory errors from creating huge bitmaps.  But the huge
bitmap is still being created, right?  So ultimately, how does this help
prevent that?  Does it process and then release (free, etc.) the memory
used by the byte[] array one chunk at a time?  Is that one reason why the
temp space size is set so low?  How much (in terms of the relative size
of the bitmaps and the data[] array) extra memory does this make
available---memory that I can use in processing the bitmap(s)?

Or should I just *assume* that it'll do whatever I want it to do,
whenever I want it to do it?

So once again, I ask:

  Can someone please either explain it, or point me to a page that
  does?

I am sure it will be fixed in whatever the next version of Android is and 
if they back port the fix and the phones get updated (likelihood: 0.0001%).

So unless you are targeting ONLY the non-yet public next version of the

 the fragment is never called. If I override onActivityResult in the
 FragmentActivity, it *IS* called. However, I don't want to handle the
 result there because it breaks the encapsulation philosophy of the new
 fragments.

 Shouldn't onActivityResult in the fragment be called? Am I missing
 something? Thanks for your assistance!

[android-developers] Dynamic loading of components

2012-04-25 Thread Hemant Chaudhari

Hello,

I have requirement just like PRISM framework in .Net.

We want to develop Android Native app such that when it starts it will 
query to internet for any additional component updates.
Once android app find updates it will download ONLY that component. It will 
not update the WHOLE app again.

Example:-

Suppose in Android App, i have 1 Tab with some functionality.
On update it should automatically show the new Tab with functionality 
downloaded from the updates.

All in all i want my application be *Dynamic*

-Thanks
Hemant

after the setFastScrollEnabled() method gets called it calls the custom 
adapter's getSections() method which is where it crashes.

 How does it error out? A crash? What's the stack trace?

 In general, the fast section indexer does not update its sections list 
 automatically when you replace the cursor. There is no method to force 
 this except turn it off and the back on after you've changed the data.

[android-developers] Backporting stagefright and NuPlayer to Android 2.2?

2012-04-25 Thread Kiran Rao

I mistakenly posted this question on the Android-Platform group
(linkhttps://groups.google.com/d/topic/android-platform/sBYyDKOoFWg/discussion).

I think it really belongs here in this group.

My requirement is to be able to play a live video stream in my Android app.
The stream will be over RTSP/RTP.
I have no control over the source; and it looks like the RTP payload does
not meet the requirements outlined in the Developers Guide Video encoding
recommendationshttp://developer.android.com/guide/appendix/media-formats.html#recommendations.

Specifically, the following requirement seems to be violated by the video
source:

For 3GPP and MPEG-4 containers, the moov atom must precede any mdat atoms,
but must succeed the ftyp atom

Basically, it looks like we get raw H264 data (not wrapped in a container).

Now,

1. I was *not* able to play this stream using the MediaPlayer class on an
Android 2.2 Samsung Galaxy Tab.
2. However, I was able to play it on an Android 2.3 Samsung Galaxy S.
3. Some third-party apps (MX Player) were able to play the same stream on
the 2.2 Galaxy Tab as well.

In both cases 2 and 3 above, the DDMS logs pointed to the fact that
StageFright framework was being used internally, while in case 1, PVP (i.e,
OpenCore) was being used. All this leads me to conclude that:

1. My stream cannot be played by OpenCore framework.
2. My stream can be played using Stagefright - even on Android 2.2

Which brings me to my question:

*What does porting stagefright to Android 2.2 involve? *

Further, I noticed in the AOSP source that the newer NuPlayer is
responsible for playing RTSP streams now. Question:

1. Is it possible at all to port NuPlayer back to older versions of
Android (2.2 or 2.3)?
2. If so, what do I need to do to be able to use it in my app?

I am aware that I can check out the sources and use NDK to build
stagefright and NuPlayer (although I have never worked at the NDK level).
What I don't know is how my app can then use this NuPlayer.

You ALWAYS need to guard against SQL injection attacks if you are forming

 Nonsense. Heck, I'll even throw in balderdash.

 On SQLiteDatabase, query() eventually calls queryWithFactory(), which
 creates the full SQL statement via
 SQLiteQueryBuilder.buildQueryString()... which does concatenation.

Re: [android-developers] BitmapFactory.Options inTempStorage

Sorry Jim, I don't know the answer... Maybe Dianne or Romain will come
across this post and they can shed some light on the subject.

And I just can't resist... I HAVE to comment on this... I find it extremely
amusing that the random quote in the signature of your last email happened
to be this:

No, I'm not going to explain it.  If you can't figure it
 out, you didn't want to know anyway...  --Larry Wall


When you just got finished asking this:

Can someone please either explain it, or point me to a page that does?


That is just way too awesome...  :-)

   While working on trying to squeeze in as much space for processing
   bitmaps in my app, I noticed this method, and from what I've read,
   believe it might help.  What I have not found, however, is a real (and
   clear) description of what it does, and how to best use it.
  
   The dev guide page suggests using it to create about 15 kB of temp
   space.  Examples I've seen from this list in the past suggest the
   same, even for as much as 9 MB bitmaps.  15 kB temp space for 9 MB
   bitmaps makes no sense to me, so I'm clearly missing something.

  I don't know for sure, but I would assume that is because it doesn't
 decode
  the entire 9 MB image at once...

 Ok, I could assume that as well (and I more or less did).  But I prefer
 actual documentation over assumptions.  And that was only one part of my
 question.  Every post I read where this was used involved using it to
 avoid out of memory errors from creating huge bitmaps.  But the huge
 bitmap is still being created, right?  So ultimately, how does this help
 prevent that?  Does it process and then release (free, etc.) the memory
 used by the byte[] array one chunk at a time?  Is that one reason why the
 temp space size is set so low?  How much (in terms of the relative size
 of the bitmaps and the data[] array) extra memory does this make
 available---memory that I can use in processing the bitmap(s)?

 Or should I just *assume* that it'll do whatever I want it to do,
 whenever I want it to do it?

 So once again, I ask:

   Can someone please either explain it, or point me to a page that
   does?

 Thanks,
