[android-developers] Re: Adding functions dynamically from application to Jar

2012-07-17 Thread Ali Chousein

You cannot extend case statements in your code dynamically, but take a look 
at the strategy design pattern 
(http://en.wikipedia.org/wiki/Strategy_pattern). I think that's what you 
need. Design patterns are not Android specific by the way, they are just a 
set of best practices in designing software.

[android-developers] Re: Handling Bitmap Out of Memory Error

2012-07-17 Thread B.Arunkumar

Hi,

   We are using 640*480 resolution video frames with frame rate of 10
frames/sec. Another question related to bitmaps is do we really need
to recycle bitmaps or can we assume that the Garbage Collector would
take care of disposing bitmaps?

Thank you,
B.Arunkumar

GC does NOT take care of recycling Bitmaps, so the answer is that YOU

public void recycle ()

... This is an advanced call, and normally need not be called, since the
normal GC process will free up this memory when there are no more
references to this bitmap.

[android-developers] Re: Handling Bitmap Out of Memory Error

2012-07-17 Thread RichardC

The GC will take care of disposing bitmaps but it is easy to create bitmaps 
faster than the GC can recover the memory from old ones you no longer have 
a reference to.  Using Bitmap.recycle() to can force memory to be recovered 
"now".

[android-developers] Clearing the RAM is not closing the whole application (i.e. all the activities)

2012-07-17 Thread xoom


Hello all,

I have 50 + activities in my application. Application is built for android 
version 2.0 onwards android devices. Everything is working fine on 2.x and 
3.x android running devices but there is a strange problem happening on 4.x 
running android devices. 

On 4.x device, after starting my app if I clear the RAM from the task 
manager i am getting an application crash. I checked the logcat prints and 
I found that when I clear the RAM, android kills my current running 
activity only (i.e. first in the activity stack). I checked the 
documentation and as per the documentation android should close the whole 
app (i.e. with the whole activity stack). But the same is not happening on 
4.x devices. Unlike 4.x, 2.x and 3.x devices kills all the parent 
activities as well and because of that  the app works without any issue on 
2.x and 3.x devices.

I am getting lots of crashes in my app because of this changed behavior. Is 
there anything I need to do in my app to handle this specifically for 4.X 
android versions.
Please help me to solve the issue it is giving lot of trouble to me.

[android-developers] Cannot insert breakpoint using gdbserver/arm-linux-androideabi-gdb

2012-07-17 Thread 郭维江

Hi,
I need to debug the native code and insert breakpoint.
The native code is based on PJSIP project and all the related libs are
assembled in libpjsipjni.so
When I running C/C++ debugger and try to insert breakpoint, this error
message will displayed and always shows when input "continue" command

(gdb)
Warning:
&"Warning:\n"
&"Cannot insert breakpoint 2.\n"
&"Error accessing memory address 0x47c58: Input/output error.\n"
&"\n"
174^error,msg="Warning:\
nCannot insert breakpoint 2.\nError accessing memory address 0x47c58:
Input/output error.\n"
(gdb)
Cannot insert breakpoint 2.
Error accessing memory address 0x47c58: Input/output error.

I have tryed to load the .so file and can see the result after "info
sharedlibrary" command
I don't know why the address cannot be accessed and cannot insert
breakpoint.
So thank you very much if you have any ideas to resolve this problem.

Here is more information:

You need to cope with just your top activity being kill anyway so why is

[android-developers] Re: Clearing the RAM is not closing the whole application (i.e. all the activities)

2012-07-17 Thread xoom

Thanks Richard for the reply.
Actually when I clear the RAM from task manager it clears all the memory of 
my application including some global variables shared between the 
activities. And when the activity restarts I am getting null pointer 
exceptions because this global variables are getting cleared. One way is to 
store the application state in bundle but is there any other way? 

If my whole application is closed then its fine, no need to preserve the 
application state also.

Re: [android-developers] Re: Unable to execute Bluetooth HDP Demo

2012-07-17 Thread wambin

For my 6 monthes reseach, I understand that below.
No one can build Android HDP application with this HDP API.
(Some people built HDP app to use Bluez with JNI. search in youtube.)
I cann't find any Android HDP app in markets.
(it has taken 6 monthes over since HDP API to be published!)
So many people have troubles about HDP demo.
Android API developers don't take any action about it.
(4.1.1 jellybean has same problems 
http://code.google.com/p/android/issues/detail?id=26704&can=1&q=hdp&colspec=ID%20Type%20Status%20Owner%20Summary%20Stars)

The only way to report the problem to Android API developers is Google 
group Android.
(http://code.google.com/p/android/issues/list)
developer.android.com dosen't publish mail address but provide this forum.
I want to add star to the HDP 
issues(http://code.google.com/p/android/issues/detail?id=26704&q=hdp&colspec=ID%20Type%20Status%20Owner%20Summary%20Stars)
 
API developers to see, if no one has solution.

2012-07-17 Thread Justin Anderson

Well, this would be one of many reasons that global variables should be
avoided like the plague wherever possible...

The correct thing to do would be to save you're application state in
onSaveInstanceState() and restore it in onRestoreInstanceState()

The reason you aren't getting an answer here is because this group is for

Your "whole application is closed" in all cases you have cited here.
Your process is being terminated by the task manager, as you can tell
by the fact that your global variables have been cleared.

Your problem is that you are assuming that those global variables
always exist and that users are always coming into your application
through one path that sets up those variables. That is not necessarily
a valid assumption -- recent tasks is just one example of a way the
user can "deep link" elsewhere in your application. One way or
another, you need to handle the case where users return to your app,
running in a fresh process, but are not coming into your launcher
activity.

You can find the database file in eclipse using the following navigation:

While your emulator is running, click DDMS in the upper right.  Then expand 
data, data, , database as shown below. From here you can

You simply cannot do that without a chrooted device.

Each app runs within its own sandbox and one application cannot do nothing

Re: [android-developers] possible to read drag in status bar notication

2012-07-17 Thread Justin Anderson

Regardless of your test case, the answer is no, you cannot do that.

In all reality though, why in the world do you want to either exit your app
or log out simply when the user pulls down the notification bar?
Personally, that would frustrate the hell out of me if I were using an app
that did that.

[android-developers] WebView in android 4.1.1 crashes for URLs with a non-standard separation of query parameters

2012-07-17 Thread sven

Hi Guys,

another problem with the new WebView in Jelly Bean (4.1.1): An app using 
the WebView crashes, when opening an URL that separates its query 
parameters not using the ampersand character ('&') but e.g. a semi colon 
(';'). 

Reproduce:
1) Call the following URL in a WebView: 
http://www.heise.de/newsticker/meldung/TomTom-baut-um-1643641.html

the German heise page will redirect you to 

  
http://m.heise.de/newsticker/meldung/TomTom-baut-um-1643641.html?mrw_channel=ho;mrw_channel=ho;from-classic=1

The page will load, but as soon as loading has finished the app will crash 
with the following stack trace:

java.lang.IllegalArgumentException: bad parameter
at  
org.apache.http.client.utils.URLEncodedUtils.parse(URLEncodedUtils.java:139)
at  
org.apache.http.client.utils.URLEncodedUtils.parse(URLEncodedUtils.java:76)
at  
android.webkit.AccessibilityInjector.getAxsUrlParameterValue(AccessibilityInjector.java:406)
at  
android.webkit.AccessibilityInjector.shouldInjectJavaScript(AccessibilityInjector.java:322)
at  
android.webkit.AccessibilityInjector.onPageFinished(AccessibilityInjector.java:281)
at  
android.webkit.WebViewClassic.onPageFinished(WebViewClassic.java:3943)
at android.webkit.CallbackProxy.handleMessage(CallbackProxy.java:325)
at android.os.Handler.dispatchMessage(Handler.java:99)
at android.os.Looper.loop(Looper.java:137)
at android.app.ActivityThread.main(ActivityThread.java:4745)
at java.lang.reflect.Method.invokeNative(Native Method)
at java.lang.reflect.Method.invoke(Method.java:511)
at  
com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:786)
at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:553)
at dalvik.system.NativeStart.main(Native Method)


Taking a look into the code of URLEncodedUtils.parse() (which is indirectly 
called by WebViewClassic.onPageFinished()) shows why: The code throws the shown 
exception if a single query parameter contains more than one equals sign ('='). 
As this class assumes query parameters to be separated by '&' the defect URL 
shown above has effectively only one query parameter from the view point of the 
URLEncodedUtils-class and thus this single query parameter has multiple equals 
signs causing the crash. 


The stack trace also shows, that the method is called indirectly in the event 
handler, so that there isn't a valid way to catch the exception.


Though the shown URL is defect it occurs in reality and I think the WebView 
should be a little more tolerant.


Best regards


  Sven

[android-developers] PendingIntent launched from widget causes onActivityResult to not be called

2012-07-17 Thread Dirk Vranckaert

I have an issue with one of my applications that is using a PendingIntent 
to launch an activity from a widget...

This is the piece of code that does the trick:
PendingIntent pendingIntent = PendingIntent.getActivity(ctx, widgetId, 
intent, PendingIntent.FLAG_UPDATE_CURRENT);
views.setOnClickPendingIntent(resId, pendingIntent);

Now let me explain you the cases:

This is the flow it should do:
[Widget]
-> Click button, launch activity
[StartTimeRegistrationActivity]
-> task needs to be selected so start TaskSelectionActivity for result 
automatically
[TaskSelectionActivity]
<- Task selected, so the TaskSelectionActivity is finished and coming back 
in the onActivityResult
-> Do some automated stuff in this activity
<- Finish the activity (so finish() and go into onDestroy())
If, from somewhere in my application, I start the activity manually (so 
without a pending intent) it's started correctly and executes correctly.

However if I start it with the PendingIntent with the flag set to 
PendingIntent.FLAG_UPDATE_CURRENT part of my flow is not executed anymore, 
specifically the onActivityResult of the StartTimeRegistrationActivity. So 
this becomes the flow:
[Widget]
-> Click button, launch activity
[StartTimeRegistrationActivity]
-> task needs to be selected so start TaskSelectionActivity for result 
automatically
[TaskSelectionActivity]
<- Task selected, so the TaskSelectionActivity is finished, but not coming 
in the onActivityResult but directly to the onDestory() method (not passing 
the finish() method anywhere)
If I change the pending intent to use the flag PendingIntent.FLAG_ONE_SHOT 
the flow is executed correctly. But then, when the 
StartTimeRegistrationActivity is open, and the user presses the back-button 
to cancel his action (a case that is perfectly acceptable for this 
application) he cannot click the button anymore because the 
PendingIntent.FLAG_ONE_SHOT declares that it will be automatically 
cancelled as soon as the send() method is called once on it.

So any ideas here how to work around it?

[android-developers] Clearing a system set notification, can it be done?

2012-07-17 Thread Matt Clark

At my school we have an internet security system, that every time your 
network connection goes inactive, it disconnects you, and you have to use 
the web browser to log back into the network. I created an app for my 
campus that detects the disconnect, and loggs the user back in with 
broadcast receivers, this part works fine, however, with my phone, it also 
detects that the network requires a login, and sets a notification:
Login to the [SSID] network.
Is there a way to after my application runs, dismiss this system set 
notification?

[android-developers] Re: Forcing lower resolution drawables on phones with big screens and small RAM

2012-07-17 Thread Matt Schoen

Hey, thanks for the reply.

I guess I should have explained more clearly.  This is a "lighter" type 
animation, which responds to accelerometer input.  The flame flickers 
(plays from a start frame on a short loop) and when you tilt the phone, the 
start frame is "swept" through an animation of the flame bending from one 
side to another.

Because of this, I'm not sure I could really "stream" anything since I 
might need any one frame of the animation at any point.  It just occurred 
to me that maybe I could store only half the frames and flip them in 
software (currently the "flip" is just rendered into the animation).

This is why I'm just using a big image sequence (about 150 frames) as 
drawables.  Any advice?

Re: [android-developers] can we restart systemserver..............?

2012-07-17 Thread Abhilash baddam

HiDianne Hackborn ,

Thanks for the reply, still I am having some doubts,

1) I read that HeadsetObserver which is a systemservice, starts whenever
headset is detected and stops working whenever we removed the headdset.
Similarly I want to start or stop particular
systemservice(PackageManagerService,ActivityMAnagerService etc...) whenever
it's required.

**

** **

Why I want to do restart the systemservices means, whenever user presess on
a button I want reload all the applications, without rebooting complete
device. instead of that I am planning to 

restart some systemservices like PackageManagerService and
ActivityManagerService because these are services which plays keyrole for
loading 

apps(SystemApps and Market apps).

** **

2) If it's not possible to restart the systemservices then I am planning to
restart the SystemServer(SystemServer .java) so that all systemservices
will be restarted, eventually all

**

apps will be reloaded without rebooting complete device.

** **

I dont know whether these are possible things or not just I am thinking. I
am ready to do Framework level changes.


Could you please suggest me as I am new to Application Framework.

[android-developers] New READ_EXTERNAL_STORAGE permission breaks file:// URIs

2012-07-17 Thread String

Throwing this out for discussion here...

Now that I have a JB device in-hand, I've found a sneaky little problem 
with the new READ_EXTERNAL_STORAGE permission. Specifically, if you pass 
another app a URI - say via a ContentProvider - that uses the "file://" 
protocol, then the receiving app NEEDS the new permission in order to read 
from that URI. Thus, the new permission has the (presumably unintended) 
potential to break an unknown number of existing apps when it enters 
production: their ContentProviders will suddenly cease to work.

I ran into this because I've re-implemented most of my AppWidgets to use 
file:// URIs for their imagery, rather than passing the bitmap directly 
through RemoteViews. [This was done as a workaround for 
http://code.google.com/p/android/issues/detail?id=17509.] And it works fine 
unless you enable the READ_EXTERNAL_STORAGE check on JB hardware, at which 
point the images fail to load due to a permission failure from Launcher.

One solution would obviously be to report this as a bug in Launcher, and 
for the appropriate team at Google to add READ_EXTERNAL_STORAGE to its 
permissions. Not a great solution, though, because it only fixes this 
single case. All other homescreen-replacement apps, from everyone from OEMs 
to indie devs, would need to make the same change. And I can promise you 
some won't.

Another possible solution would be for me to keep these images in internal 
storage, making them world-readable so the URI recipient can read them. I 
haven't tested this to see if it'll work, but even assuming it does, it's a 
change that anyone who generates a file:// URI would need to make. And 
probably, some of them are generating URIs to files that can't reasonably 
be moved to internal storage. So we're back in the business of breaking 
existing apps.

I don't know the internals well enough, but is it possible that there's a 
solution that could be implemented at the platform level? That whatever 
platform mechanism fulfills file:// URIs would bypass the 
READ_EXTERNAL_STORAGE permission check?

Or is this by design, platform team? If so, I think it really needs to be 
publicized.

Comments?

[android-developers] Re: Forcing lower resolution drawables on phones with big screens and small RAM

2012-07-17 Thread Nobu Games

You still could go with the "streaming" idea. At any given time you would 
have a fixed size amount of frames in memory (let's say 15 bitmaps, just as 
an example). As the animation progresses you need to load the next batch 
and discard older ones. In order to prevent loading hickups you could 
proceed as follows:

   - Your "window" of animation bitmaps has 15 items.
   - As the animation counter reaches item #6 you would recycle the last 5 
   ones and load the next 5 ones that come after item #15
   - Loading needs to be done in a background thread (AsyncTask)

Of course you'd need to add special logic for your case, like allowing to 
loop a certain amount of animation frames and starting playback from any 
point of the sequence and so on. But this could be done with a fixed size 
window of frames.
I think that's the only sane way to do that based on that huge bitmap 
sequence and you could even adjust the window size according to the 
available memory. Play around with these numbers in order to get the best 
result for your animation.

By the way, I would just animate the flame itself and use a single, static 
bitmap for the lighter. That way you could use a low-resolution bitmap 
sequence of the flame and scale it up on devices with less memory. Lights 
and shadows could be faked in real time, too, by drawing overlays on the 
view's canvas.

Maybe you can get away with that solution and don't need to implement a 
streaming technique.

Re: [android-developers] New READ_EXTERNAL_STORAGE permission breaks file:// URIs

2012-07-17 Thread Dianne Hackborn

You can put your data in your own content provider.

Actually, you should stop and think about doing this approach at all.  You
say this is for an app widget...  why not provide the bitmaps as bitmaps
instead of having it load the data elsewhere?  Note that if you don't
provide the bitmaps directly, anything you do means you are making this
data globally readable by everyone (because you can't make any assumptions
about the permissions available to whoever is hosting your app widget),
which is generally a big no-no for security reasons.

This isn't a launcher bug.  Launcher is just one possible host of app
widgets.  You can't assume whoever is hosting your app widget will have any
specific permissions.

Also this is why the protection in JB is turned off by default.  Right now
app developers should be updating their apps to fix these issues, so when
this protection is turned on for all users in a future release they will
still work.

Btw this change is described in the permissions section of the 4.1 API
overview:  http://developer.android.com/about/versions/android-4.1.html

This isn't anywhere nearly possible with the SDK

Are you doing platform modifications?  If so then android-platform is
the list you want,

Furthermore, I'm not sure this really makes sense, there's not support
to just "reload all the apps."

Re: [android-developers] can we restart systemserver..............?

2012-07-17 Thread Dianne Hackborn

You can't.  Asking the same question again doesn't change the answer. :/

And good ghod, no of course you can't restart the freaking activity manager
without restarting all the apps.  I mean... come on!

You haven't actually said what you are trying to do, but the path you are
going down here is almost certainly wrong for whatever it is.  Restarting
something like the activity manager is not in any way shape or form correct
as a normal part of the system operation.

That's really up to you and your use case. Generally "hey, there's an

It's more that anyone using URI values from third-party sources need
to add the permission, if there is a chance that such URI values point
to external storage. They would already need WRITE_EXTERNAL_STORAGE if
they would try writing to such URIs, though admittedly that is less
common.

Which is why we need to publicize this more. I have been holding off

That would pretty much eliminate the purpose of the permission.

Yes, but the old Preference mechamism still works, at least in 4.1.

You actually don't need to use findPreference --

Rather, create a Preference subclass, override onClick, and launch the main
activity with an intent that includes Intent.FLAG_ACTIVITY_CLEAR_TOP

( or call the preference activity's finish, if your stack only has the main
activity and the preference activity at this time ).

[android-developers] Table Row Selection when using SimpleCursorAdapter

The subject says it all.  How can I allow a user to select a row from a

I'd done this previously by dynamically building each table row from a List

efficient.

I was doing that some time ago, but then I stopped because this imagery is 
already cached on SD, so I figured it was more direct to just pass through 
a file:// URI. I'll look into reverting it; thanks for the reminder.

Actually, you should stop and think about doing this approach at all.  You

The full discussion is 
here: 
https://groups.google.com/d/topic/android-developers/oAl2Ix9erSY/discussion

The summary is, passing middling-large imagery to a widget doesn't work; 
IPC fails silently. The content provider was the recommended workaround, 
and it's done well until now.

Understood. The widgets in question aren't a security risk (I'd be quite 
interested if someone found a way to reuse my imagery), but it's a good 
point for other widgets.

That's what I said in my OP, yes. To fix this from the content-consumer 
side, every appwidget host out there would have to request the new 
permission. Which isn't likely.

Which brings me back around to my main point: this is a permission change 
that needs to be made *in an app other than the one that's failing*. The 
file:// URI content provider can't make the change; it's the 
content-consuming app that needs to request the new permission. And that's 
not in the docs, nor is it something that's necessarily obvious to the 
content-consumer dev, especially if the testing they're doing is with 
non-file URIs.

You say it's not a Launcher bug; I do see your point, but I've had 
differing opinions on that. If Launcher is happily accepting file:// URIs 
that point to external storage, shouldn't it be requesting the appropriate 
permission to resolve that URI?

This is what concerns me. There's nothing in the docs that mentions the URI 
implications of this change, so URI-consumers probably aren't thinking of 
it. I'm looking beyond my own widget issues here.

Re: [android-developers] Preferences button to return to main activity

2012-07-17 Thread billb

Thanks for the ideas!

A quick question about subclassing Preference.  The only place I use 
Preference directly is in XML to define the button.  If I create a subclass 
of Preference can I then use that new class name in the XML directly in 
place of the  tag (e.g. )?

If not, where do I instantiate the MyButtonPreference subclass?

I'm still getting comfortable with the whole Android paradigm, so I 
apologize if this is something that seems straight-forward.

As they say, everything is easy once you know how.

Yes you can, except it'll need to be something like:



... etc.

Basically, same thing you'd do with a view subclass - using a fully

It is, so that's the more "correct" method, using PreferenceFragments. But
if you don't want to go through that (yet), then this is probably the
quickest and easiest way to achieve what you want. I use this a lot, it's
like 3 lines of code, it's still working fine and I have no intention of
moving to Fragments any time soon.

I would really suggest reducing the memory of your bitmaps then.  This
limit is actually important -- if you are pushing huge bitmaps into the
launcher, you run the risk of the launcher failing when it exhausts its
heap due to them.

We have limits.  Limits are important.  Respect the limits. :)

Not sure what you mean "not in the docs" -- it is described in the document
I pointed to.  I do agree that there should be more discussion of this, and
I can assure you there will be -- that is why we are doing things this way,
to have the facility in place for JB for developers to test against before
a later change actually impacts apps.

No.

We are pushing to get away from the free-for-all of external storage; this
is one of the steps in that.  We want a system in which as few apps as
possible are requesting these permissions.

Can't you use a content provider that implements openFile() and uses
ParcelFileDescriptor to return a reference to the same file(s) you have on
the external storage?

This, too, would avoid the unnecessary copying of bitmap data.

IIRC, content:// URIs are supported by ImageView since 2.2.

What isn't documented is the impact on URI consumers, who don't think 
they're using external storage, so they don't think they need the new 
permission. My goal here is to publicize the fact that the new permission 
is required by such apps, who aren't reading external storage directly.

2012-07-17 Thread Francisco M. Marzoa Alonso

Maybe I'm wrong, but I think he pointed that the frame sequence depends on
user input, so he cannot preload a series of frames because each next frame
varies with user interaction on previous one.

[android-developers] Re: Forcing lower resolution drawables on phones with big screens and small RAM

2012-07-17 Thread Matt Schoen

Unfortunately I've already done your last suggestion.  The images are 
pretty small already.  I'm still not convinced that the streaming would 
work.  For one thing, the flicker loops, and for another, the range of 
frames changes quite often.  For example:

If the phone starts upright, we play images 90, 91, 92, 93, 94, 95, 90, 
91...

Then, if you til it, it'll be like 90, 91, 92, 80, 81, 82, 60, 61, 62, 40, 
41, 120, 121, 140, 141...
^   ^   
^  ^^

The carats signify where the accelerometer value has changed so that the 
"first" frame is different.  This happens quite frequently (to make for a 
smooth "bend") and is completely unpredictable.  As far as I can tell, we'd 
always get a hiccup when the accelerometer value changed.

I'm really hoping that I can do what I was originally asking for.  It seems 
so simple to just force the loading of a different set of drawables.

If I wanted to load the images some other way (not through the drawables 
folder) how could I do that?

Yes, I can revert to that; as I mentioned earlier, I had been doing that at

support pre-2.2. But that's not a big deal.

Re: [android-developers] Preferences button to return to main activity

2012-07-17 Thread billb


This sounds like exactly what I need.
 
I've done some searching and have found the "finish()" method for 
PreferencesActivity, however, I am now at a loss on how to call this method 
from within the Preference subclass.
 
I have this so far:
 
public class GoHomePreference extends Preference
{
 public GoHomePreference (Context context)
 {
   super(context);
 }
 
 @Override
 public void onClick()
 {
  ??.finish();
 }
}
 
Once again I apologize for my lack of experience.
 
also, Thank you for your advice.

Yes, it is possible since AFAIK you can access diretly to any resource by
itself path, instead of using th resource id.

I am connected through my phone now and have no time to find the exact
method, but googling a bit you should find it fast, probably on

Have you considered or tried using:

Maybe you can fake flame flickering by animating mesh vertices instead.

Is there a limit for the number of thread created by an Android activity

If yes, how can I find out such limit?
