I am needing to draw shapes which will have hollow regions.
To simplify the idea, take an ampersand sign : 
This is just to illustrate the kind of task I need to do.

I can create the outline by using a path.
However, I have not been able to see how to create the two holes such 
that when the paths are painted, they will appear as ... holes.

Can anyone guide me with this one ?

[android-developers] Re: Drawing complex shapes with hollow parts

Thank you for this.
One thing I am not clear with is the problem with hardware acceleration.
Some people say that this will not work with hardware acceleration ON, 
whilst others say that this is precisely what is needed when it is ON.

Is there some definitive answer for this aspect ?

hi
 
I am looking for a custom component which will behave like a wheel.
actually I have to show the some number, which will start with zero and 
goes upto particular value (say from 0 - 1000).
In detail it should work like this.
upto 1000 I have to show 4 images and on the top of it I have to show 1 
digit per image programmatically.
whe we start with 0 that time only one image is visible, the movement my 
count reaches 10 it should make another image visible and on reaching 100 
it should make another image visible and so on ant by the time my counter 
should keep on increasing.
This control should look something like this. I have attached the screen 
shot of the control how it should look likr.
 
Need urgent help on this

Thanks - I read that post; it seems to be stuck in the same place I am. 

I suspect a memory leak that is keeping some app state alive across app 
shutdown and restart, and what I'd really like is some easy way to analyze 
what memory isn't being reclaimed when Android closes my app.

 ACRA keeps track of initialization using a static variable, so with 
 multiple processes 
 this should not happen. I've seen this too in error reports, still no 
 idea why it happens. 
 Here's a related issue:

There was a bug filed for this on the emulator, when used with a proxy.
Search on http://b.android.com.

Does it happen on all devices, only on a certain device, only on the emulator?
If you are hitting a but in the framework (of which HttpClient is a part of)
on some particular version , the only way to avoid is to bundle a
newer version in
your app, or use HttpUrlConnection or some other HTTP client library.

And yes, unless you are doing something special, chunked encoding should be
handled automatically.

[android-developers] Re: Application onCreate called more than once?

2012-11-12 Thread Streets Of Boston

The onCreate of an Application (subclass) is called exactly *once *for each 
instance of a DalvikVM. 

If Android kills your app's process, it stops the DalvikVM instance as 
well. There is no way to 'hold on' to any reference, since you DalvikVM 
instance that was running your app no longer exists.

Your app can, however, use more than one process. I don't know if the ACRA 
code runs in its own process and not liking being used by two or more 
processes running the same package (your app).  

More info is needed to figure this one out.

 11-09 11:53:40.394
 11-09 11:53:40.744
 11-09 11:53:41.364

 I am using a Service, but only through onHandleIntent, and I did not 
 register it to run in a separate process. 

 My theory is that I'm holding onto some reference which is preventing my 
 app from being stopped (and garbage collected).

 Does this make sense? If it does, is there a good way to track down what 
 reference or references could be causing this? My app is rather large 
 (about a dozen activities, a handful of async tasks, a few 
 broadcasters/receivers, etc.), so I was really hoping for a good way to 
 track these down.

You may also need another thread to increment the count.  Also, use a

That way you can use 10.5 and the last digit will be halfway between 0 and 
1.

[android-developers] Can dynamic broadcastreceiver receiver intent from other apps?

2012-11-12 Thread Jin

Hi,

I encountered a problem with dynamic broadcastreceiver.
I send an intent using sendBroadcast from App B, and it can be received in 
App B by both static receiver and dynamic receiver. 
However, when it comes to App A, it can only be received by static receiver.

I find on developer site that registerReceiver (BroadcastReceiver 
receiver, IntentFilter filter) is to Register a BroadcastReceiver to be 
run in the main activity thread. The receiver will be called with any 
broadcast Intent that matches filter, in the main application thread.

So, does this mean that dynamic broadcastreceiver can only receive intent 
in its own main application thread, and cannot receive intent from other 
apps?

You can see a dynamic-registered BroadcastReceiver receiving

 No. 

 You can see a dynamic-registered BroadcastReceiver receiving 
 broadcasts from other processes in many places, such as this sample of 
 receiving ACTION_BATTERY_CHANGED:

 Just like you could do in an Activity. Registering onClickListeners in

[android-developers] Samsung not in SDK manager list

I am using Eclipse Indigo service release 2.
The version of the ADK is 20.0.3.v201208082019-427395.

When I open the SDK Manager, I noticed that there is no mention of anything 
from Samsung.
Looking into the Add-on sites, Samsung is not there and the User Defined 
Sites is empty.

Are we able to get SDK and device stuff from Samsung via this method any 
more ?
If so, what do I need to put into the user defined sites to get this to 
work ?

[android-developers] Heap size driving me crazy

Hi!

Im making a game for android, Im about halfway trough (its my first real 
game that Im planning to release) and I just started using DDMS, and 
realised that my heap-size was at around 30 000, with a leak on around 3000 
every time I changed level. So I created a method that loaded my bitmaps 
with only 3 colors, and this reduced my heap-size down to 20 000, and I 
suspect that the memory leak is because the menu I have in between levels 
(with score etc) is a new activity started in realtime, Im gonna change 
this to a dialog-box so I never have to leave the main-activity in 
realtime. 

But obviously 20 000 heap size is still to much! I need to get down to 16 
000, and like I said, I'm only halfway done. I Only have 5-6 different 
bitmaps onScreen at a time, sure there is around 5-6 enemies on screen that 
are using the same bitmap, aswell as several bullets using the same bitmap. 

So after all that, my question is, is there any common mistakes that 
beginners do that increases heap-size that I might have done? I've been 
reading about it for weeks and watched a couple of google-lectures on 
youtube. But nothing that really helps. Ive been trying to isolate the 
problem by removing 1 class at a time, then starting my game, but dosnt 
seem to go down. Going crazy! Been working for 6-7 months and now it might 
end up in the trash =/.

Removing a class is not a solution to heap issues. It's not even related to 
heap issues.

The most common issue with heap exhaustion is packratting, the failure to 
release references.

Consider an instance created an added to a 'Set':

  SetFoo foos = new HashSetFoo();
  foos.add(new Foo());

Now the collection 'foos' holds a reference to that new 'Foo'. Unless that 
element is removed 
from the collection, that instance cannot be garbage collected (GCed).

ANother common error is to allocate an instance for too long a lifetime:

  Foo foo = new Foo();
  while (someCondition()) 
  {
setAttributesFromResource(foo);
doSomethingWith(foo);
  }

The instance pointed to by 'foo' will live as long as the loop takes. 

  while (someCondition()) 
  {
Foo foo = new Foo();
setAttributesFromResource(foo);
doSomethingWith(foo);
  }

Each 'Foo' instance will go out of scope at the end of each loop iteration, 
and can be GCed then.

This is dangerous if there's a 'foos.add(foo)' inside that loop, for the 
aforementioned reason - each 
'foo' will be referenced by the collection and cannot be GCed until the 
collection releases it.

Another problem is objects that use lots of resources, like native memory, 
if they don't release those 
resources in a timely fashion. 

The bigger the object's heap footprint, the worse the problem.

So make sure object references go out of scope or are otherwise removed the 
instant they 
aren't needed.

Have a careful look at the source code for this game Replica Island:
http://code.google.com/p/replicaisland/

Specifically the all the Objects that extend:
http://code.google.com/p/replicaisland/source/browse/trunk/src/com/replica/replicaisland/AllocationGuard.java

When the game is running almost no dynamic objects are allocated, they are
mostly pre-allocated and held on free lists and re-used. This is to try
and avoid a GC during a level which could seriously affect the feel of the
game. It also gives finer control of the amount of memory used in the game.

[android-developers] HLS Stream with Discontinuities reports incorrect position (4.0.x)

2012-11-12 Thread Rick Gavin

When using an HLS playlist with multiple segments of content spliced 
together ( separated by EXT-X-DISCONTINUITY tags ), 
MediaPlayer.getCurrentPosition() doesn't return the correct position.  In 
this scenario, each piece of content has its timestamps starting from zero. 
  So for example, if at the 4 minute mark, there is a Discontinuity flag 
followed by a new piece of content, getCurrentPosition() reports the time 
as going back to 00:00 instead of 04:01  

Does anyone know a work around?   

Just a note that MediaPlayer.getDuration() does correctly return the full 
duration of all the content combined.

 HI,

 first: USB-Host including the USB-Host api works for me on the Nexus 7 -

 You could try an app like USB Device Info to validate your hardware

 I have setup intents and filters, but I also assume they are not necessary
 if you scan for devices yourself.
 As I understand it, you just tried a mouse and a phone? I just made a test
 with a mouse and though USB Device Info saw it on the linux tab, it did
 not see it on the android tab. My app also did not see the mouse. I
 assume since android handles the mouse itself, it does not make it visible
 to the app.

 I.e. try another usb device. If you can see it on the Android tab in USB
 Device Info, you probably should see it in your app.

 Hi All,
 I recently bought a Nexus 7 for USB development.  I would like to use the

 USB Host Tutorial at the link: http://developer.**
 android.com/guide/topics/**connectivity/usb/host.htmlhttp://developer.android.com/guide/topics/connectivity/usb/host.html
 .

 My program is very simple, and here are the relevant parts of the code:

 *private UsbManager manager;
 *
 * *
 *public void onCreate(Bundle savedInstanceState) {*
 *super.onCreate(savedInstanceState);*
 *setContentView(R.layout.activity_main);*
 **
 *Log.i(TAG, in onCreate());*
 *manager = (UsbManager) getSystemService(Context.USB_SERVICE);*
 *if(manager==null) {*
 *Log.i(TAG, USB Manager is NULL);*
 *}*
 *else {*
 *Log.i(TAG, USB Manager =  + manager);*
 *}*
 *}*
 **
 *public void enumerateUSBDevices() {*
 *HashMapString, UsbDevice deviceList = manager.getDeviceList();*
 *CollectionUsbDevice deviceCollection = deviceList.values();*
 *IteratorUsbDevice deviceIterator = deviceCollection.iterator();*
 *Log.i(TAG, Number of connected USB Devices =  +
 deviceCollection.size());*
 *while(deviceIterator.hasNext()){*
 *UsbDevice device = deviceIterator.next();*
 *Log.i(TAG, device.getDeviceName());*
 *}*
 *}*


 When the enumerateUSBDevices function is called, it reports that the
 number of connected USB Devices = 0.  I am using a USB OTG cable, and I
 know that the Nexus 7 is powering the connected USB Device because I
 plugged in a USB Mouse, and it works properly.  I also plugged in another
 Android phone, and the Nexus 7 was confirmed to be powering the device.
  However, in both of these instances, the Android program says that there
 are no USB devices connected.  I am unsure what is going wrong in my code.
  In my Android manifest, I have the following line:

 *uses-feature android:name=android.hardware.usb.host /*

 My manifest does not have any intent filters associated with any USB
 devices.  My understanding based on reading the tutorials is that the
 intent filters need to be in the Manifest only if you want the APP to be
 notified when the USB device is connected after the App is running?

 Can anybody shed light into what I may be doing wrong?  Do I need to root
 my device?

 Thanks,
 Kiran

 Any ideas on what could possibly be causing this exception?


 This has been brought up a few times before. We've all seen crazy
 exceptions that should not happen, but they do. You can probably safely
 ignore these. Unless they're in an exceedingly high volume ... ?

[android-developers] Re: Samsung not in SDK manager list

2012-11-12 Thread Zsolt Vasvari

As far as I know, you could never get Samsung add-ons via the SDK Manager.

On Tuesday, November 13, 2012 3:17:04 AM UTC+8, Simon Giddings wrote:

 I am using Eclipse Indigo service release 2.
 The version of the ADK is 20.0.3.v201208082019-427395.

 When I open the SDK Manager, I noticed that there is no mention of 
 anything from Samsung.
 Looking into the Add-on sites, Samsung is not there and the User Defined 
 Sites is empty.

 Are we able to get SDK and device stuff from Samsung via this method any 
 more ?
 If so, what do I need to put into the user defined sites to get this to 
 work ?

[android-developers] Re: Application onCreate called more than once?

2012-11-12 Thread Zsolt Vasvari

  Post your manifest.xml. I assume that you have your broadcastreceiver or 
some service running in a separate process. That would cause 
Application.onCreate to be called multiple times.

It would?  Please provide a source for this piece of tidbit.
