Re: [android-developers] Resource qualifier bugs in Honeycomb/xoom

[Brill Pappin]

Ahh, that explains the missing night mode, although if there is no dock mode 
(which is obviously a bug since I have it in a doc) when there can't be a 
car mode.

[android-developers] Facebook and twitter integration

[Laxmi Verma]

Hi,

I want to integrate facebook and twitter into my android app.  Everwhere I
found the code of showing the dialog box of facebook and twitter login and
then posting the content from there.
What I want to do is, on twitter or facebook button click it should forward
to twitter site for e.g. m.twitter.com and my article id should get
displayed in the tweet box (twitter) or walll post box (facebook) in the
site directly.
Just like it has done in ndtv app.
Please do help in this.

Thanks & Regards,
Laxmi Verma

Re: [android-developers] Resource qualifier bugs in Honeycomb/xoom

[Dianne Hackborn]

Night mode only applies when in car mode, as always.  The Xoom doesn't have
a dock mode -- when you put in the dock you will notice it doesn't do
anything special.

[android-developers] Display large html content page wise in WebView

[Sourav Howlader]

Hi All,

I have a large HTML which contents huge number of lines. But I want to
show content of the HTML file that fits a single screen.

I want to provide a " > " button to show the next contents of the same
HTML file.

I want to only display the HTML contents that fits the screen similar
to eBook reader application. For user, it seems there are several
pages.

Is there any way in which I can achieve this functionality. If yes,
how to do it ?

Thanks in advance.
Sourav

[android-developers] AdWhirl: Ads not getting displayed.

[Mahavir Jain]

I really having trouble in displaying Ads through AdWhirl.

Following is the code:

AdWhirlTargeting.setTestMode(true);
AdWhirlAdapter.setGoogleAdSenseAppName(APP_NAME);
AdWhirlAdapter.setGoogleAdSenseCompanyName(COMPANY_NAME);
final DisplayMetrics dm =
showComments.getResources().getDisplayMetrics();
AdWhirlLayout adWhirlLayout = new
AdWhirlLayout(showComments, MyWidgetProvider.ADWHIRL_SDK_KEY);
adWhirlLayout.setMaxWidth((int) (dm.density * 320));
adWhirlLayout.setMaxHeight((int) (dm.density * 52));
adWhirlLayout.setGravity(Gravity.CENTER);
//LayoutInflater inflater=showComments.getLayoutInflater();
View header=inflater.inflate(R.layout.header_layout, null);
FrameLayout
ad_frame=(FrameLayout)header.findViewById(R.id.ad_frame);
ad_frame.addView(adWhirlLayout);

showComments.getListView().addHeaderView(ad_frame);

But Ad never get display. I have set up the SDK key for AdWhirl, AdMob and
InMobi. I also have INTERNET permissions. I set up all the the keys one day
before. I am calling this in main UI thread. And I am testing this on
emulator with test mode set to TRUE.

Following is the LogCat:

Your activity is starting, but the activity is crashing because your
XML references net.youmi.android.AdView and that class isn't found.
Most likely your forgot to include the youmi AdView jar. Test first
without ads and then add them when you have it working.

Re: [android-developers] Action bar through compatibility lib on 1.x, 2.x API

[Brill Pappin]

How the heck is that ActionBarBC project built?
It's min version is 4 so it should not allow the 
supports-screens android:xlargeScreens="true"

Are we to build with 11 even if we are compatible with 4?

[android-developers] Resource qualifier bugs in Honeycomb/xoom

[Brill Pappin]

After having some unexpected things happen when writing for Honeycomb on an 
xoom, I notice that a couple of the resource qualifier options seem to be 
broken.

Specifically:
Dock Mode: not set even when in the dock.
Night Mode: notnight at 11:30 PM EST

Is anyone else noticing that happen in honeycomb in general or on the xoom 
specifically?

I've created a little app for testing this as I was testing often enough on 
different devices :)
http://dl.dropbox.com/u/62099/itapdevinfo.apk

I have no idea if this is a general Honeycomb thing or if its specific to 
the xoom's implementation, but I'm thinking it would be worth finding out 
 so it can be reported.

[android-developers] Re: How to change Application theme

[Nicholas Johnson]

Set your theme at run time in the onCreate() method using setTheme(int). Check 
it out 
here
.
 
I do this with my app, and it works very well. My onCreate() method looks 
something like this:
 
public onCreate(Bundle b) {
 
/* Get your preference here */

/* Set the theme before calling setContentView() */
switch (theme) {
case X:
setTheme(R.style.theme1);
break;
case Y:
setTheme(R.style.theme2);
break;
}
 
super.onCreate();
setContentView(R.layout.layout_name);
}

Why are you creating a new overlay for each marker? To stay with your story, 
one overlay per bus line would make much more sense.

[android-developers] PendingIntent question

[dashman]

i create PendingIntent and notification from a service.

PendingIntent contentIntent = PendingIntent.getActivity( 
context, 0,
notificationIntent, PendingIntent.FLAG_CANCEL_CURRENT );

it creates a notification, user taps on the notification and then
the activity gets called...

works fine.

what i'd like to do is to call the activity immediately from the
background service and then have the notification act as more
of a message to user that the activity was called.

Isn't that the point of 9-Patch?

I haven't actually used the tool, but another idea is have a nested layout
with your "header" or whatever that is not supposed to stretch and then the
"real" LinearLayout with the portion that does stretch, both within a parent
LinearLayout.

Tip: when stuff doesn't show on the map, try zooming all the way out in case
you've plotted it wrong 

Walk with me here ...

This is your format, right?:-79261518<>44006280<>2511<>YRT
And this is your parsing, right?: LineSplit[0]),Integer.parseInt(LineSplit[1])
...
And this is your function, right?: AddOverlayItem(int intLat, int intLong
...
So -79261518 is latitude, 44006280 is the longitude right?
And this becomes -79.261518 and 44.006280, right?

Is this a transit system for
Penguins
?
Or for 
Ducks
?

Re: [android-developers] Activity#onRetainNonConfigurationInstance vs Fragment#setRetainInstance

[Dianne Hackborn]

This doesn't work.  It is still associated with the original
context/activity, so at the very least you are now leaking that object and
worse it may be trying to do stuff with it (such as use the WindowManager
service) that is now on a context that is no longer live.

Re: [android-developers] Activity#onRetainNonConfigurationInstance vs Fragment#setRetainInstance

[Shri Borde]

It actually worked with Fragment#setRetainInstance. I just had to call
((ViewGroup) fragmentLayout.getParent()).removeView(fragmentLayout) before I
could reuse the views.

I got crashes in native code when I tried doing the same with
Activity#onRetainNonConfigurationInstance.

[android-developers] Re: Action bar through compatibility lib on 1.x, 2.x API

Oh well then I think the expected fragment*support work good on pre-
HC.

Just got a bit greedy to see if the action bar can show up on top
replacing the title bar (as in HC).

Thanks for your reply.

You pretty much hit the nail on the head. I just need to figure out

[android-developers] Re: Capture keyEvent from view displayed by WindowManager.addView()

[Bruce Xia]

Don't be scared. What I'm trying to do is for user to be able to
define a set of actions for specific keys, display a window and
capture it when the event triggers my service. They will install the
service as normal and if they don't like it they can remove on the
fly.

If it's available when the view added to activity it should be
available if it's displayed from a service. Something is missing after
the addView process.

Also why the OnKeyDown/OnKeyUp not work even the view was on an
activity?

My interpretation of what you're trying to accomplish is that you have
1+ activities that need to hear about scan results, for a startScan()
kicked off every so often.

Let's assume a service being bound to by the activities is the right
answer. I'm more than a tad skeptical on that, actually, but I'm
trying to keep this simple relative to your apparent current
implementation.

Step #1: In onCreate() of the service, you register a
BroadcastReceiver for SCAN_RESULTS_AVAILABLE_ACTION, then call
startScan(). onCreate() then returns. Or, if this should not be going
for the entire time the service is in memory, expose a method from
your Binder that does the aforementioned work and returns.

Step #2: When SCAN_RESULTS_AVAILABLE_ACTION occurs and your
BroadcastReceiver is called with onReceive(), you:

Step #2a: Arrange for your next scan (e.g., use Timer/TimerTask to
call startScan() after some delay -- I agree that AlarmManager is not
ideal for this particular implementation)

Step #2b: Call getScanResults() and asynchronously notify the
activities (your own broadcast Intent that the activities register
for, or via a callback method the activities register with the
service, or via a Messenger, or via a PendingIntent created by
createPendingResult(), etc.).

Step #3: In onDestroy(), you unregister your BroadcastReceiver and
arrange to not invoke the next scan (e.g., cancel the Timer).

[android-developers] Re: Calling a system service in fixed intervals within another service

[Diego Tori]

That's the thing, it has to be short intervals in between scans since
this has almost real-time implications, no greater than 15 secs at
most, so I dunno how AlarmManager would fit into the equation. Is
there any chance you can show me how to modify the above code to
utilize AlarmManager to have it sleep before the onReceive gets called
again?

[android-developers] Calling a system service in fixed intervals within another service

[Diego Tori]

As the question implies, I am wondering how I could write a thread
that would call a system service and then wait a certain amount of
time before calling said system service's function that calls back to
onReceive from a registered BroadcastReceiver.

In other words, I am trying to call the Wifi scanning service
(registering a BroadcastReceiver with IntentFilters) within my custom
local service so I can get the current SSID's available and send them
back to the activities that are bound to this service. I know what I
will end up doing with the received data, which is not relevant to
this question. However, I will need to wait a certain amount of time
before calling startScan again within onReceive, and that is where I
am trying to determine the best course of action.

Here is what I have so far:

class MyWifiScanner extends BroadcastReceiver implements Runnable{
private boolean running;
private final int SLEEP_TIME = 1;
private Object mSync = new Object();
WifiManager wifiMan;
Thread t;
public MyWifiScanner(){
//receiver registered with intent filters
wifiMan = (WifiManager)
SSIDListenerService.this.getSystemService(Context.WIFI_SERVICE);
t = new Thread(this);
t.start();
}

@Override
public void onReceive(Context context, Intent intent) {
//Received WiFi access point names, handle them
//Should I call wait on a sync object while syncronized 
with it for
said amount of time and then call notify???
syncrhonized(mSync){
mSync.wait(SLEEP_TIME);
mSync.notify();
}
}

@Override
public void run() {
while(running){
syncrhonized(mSync){
wifiMan.startScan();
}
}

}
}

Or would it make sense to just create a BroadcastReceiver object that
just calls Thread.sleep in the end of onReceive?

[android-developers] Re: Backward compatibility when compiling.

[sblantipodi]

I'm talking about SDK now, at the moment I'm interested in adding this
attribute
but I want to be sure that I will not have any problems with android
1.6.

In the docs is written that previous version of android simply skip
the attribute,
but I just wanted to have a confirmation of people who tryed building

[android-developers] Capture keyEvent from view displayed by WindowManager.addView()

[Bruce Xia]

Hi,
I have a view which basically cover the full screen to capture key
input. It works well if I add it to activity, but if I display it from
background service using WindowManager.addView, it doesn't work.

Another quesiton is why onKeyDown/onKeyUp doesn't work? As you see I
have to use  setOnKeyListener(mkeylistener);


class myView extends TextView {
private Paint mLoadPaint;
private final String TAG="HUDView";

OnKeyListener mkeylistener= new OnKeyListener(){
public boolean onKey (View v, int keyCode, KeyEvent event){
Log.d("mkeylistener", "onKey:"+keyCode
+":Keyaction:"+event.getAction());
return true;
}
};
public myView(Context context) {
super(context);
//Toast.makeText(getContext(),"HUDView",
Toast.LENGTH_LONG).show();

mLoadPaint = new Paint();
mLoadPaint.setAntiAlias(true);
mLoadPaint.setTextSize(10);
mLoadPaint.setARGB(255, 255, 0, 0);
setOnKeyListener(mkeylistener);
setFocusable(true);
setFocusableInTouchMode(true);
this.setText("TEST");
this.setLayoutParams(new
LayoutParams(LayoutParams.FILL_PARENT,LayoutParams.FILL_PARENT));
setOnFocusChangeListener(new View.OnFocusChangeListener(){

@Override
public void onFocusChange(View arg0, boolean 
arg1) {
// TODO Auto-generated method stub
Log.d(TAG, arg0.toString()+":"+arg1);
}

});
}
@Override
public boolean onKeyUp (int keyCode, KeyEvent event){
Log.d(TAG, "onKeyUp:keyCode"+keyCode);
return true;
}
@Override
public boolean onKeyDown (int keyCode, KeyEvent event){
Log.d(TAG, "onKeyDown:keyCode"+keyCode);
return true;
}
@Override
protected void onAttachedToWindow (){
Log.d(TAG, "onAttachedToWindow");
requestFocus();
}
@Override
protected void onDraw(Canvas canvas) {
super.onDraw(canvas);
//canvas.drawText("Hello World", 5, 15, mLoadPaint);
}

@Override
protected void onLayout(boolean arg0, int arg1, int arg2, int
arg3, int arg4) {
}

@Override
public boolean onTouchEvent(MotionEvent event) {
//return super.onTouchEvent(event);
Toast.makeText(getContext(),"onTouchEvent",
Toast.LENGTH_LONG).show();
Log.d(TAG,String.format("top:%d,bottom:%d,left:%d,right:%d",
this.getTop(),

this.getBottom(),this.getLeft(),this.getRight()));
Log.d(TAG,"ontouch, is focused?"+this.isFocused());
testactivity.this.finish();
return true;
}
 }

Re: [android-developers] Action bar through compatibility lib on 1.x, 2.x API

[Dianne Hackborn]

The compatibility library provides fragments and loaders on pre-HC devices.
 It does not have any other major features; it just has a smattering of
helpers for small specific methods that don't exist on older platforms.

Re: [android-developers] Activity#onRetainNonConfigurationInstance vs Fragment#setRetainInstance

[Dianne Hackborn]

Sorry, you just can't re-use a WebView across config changes -- a view is
instantiated with a Context it runs in, which is the Activity that created
it.  You can't change this context later, when you have a new Activity
instance.

Re: [android-developers] Re: How to Get List of all Devices Connected to the Same Wi-Fi Network

[Kostya Vasilyev]

Robert,

You need to do *something* like that, enumerating the devices on the 
network.


How exactly, well, probably not with address.isReachable(), as that 
seems to be unreliable (search the group for more information).


The right way is going to depend on what exactly you are trying to discover.

For example, there is a UPnP discovery protocol for UPnP devices (Google 
for Java libraries that can do that).


You can also discover NetBIOS nodes, but in a different way from 
discovering UPnP devices.


Etc, etc, etc.

I've even tried this piece of code:

   byte[] ip = InetAddress.getLocalHost().getAddress();

   for (int i=1; i<=254; i++)
   {
  ip[3] = (byte)i;
  InetAddress address = InetAddress.getByAddress(ip);

  if (address.isReachable(1000))
 Log.d(LOG_TAG, "Name: " + address.getHostAddress());
   }

But all I get is the loopback address.

Have you tried my suggestion from early on in the thread: profile your app when

[android-developers] Re: onSaveInstanceState(Bundle) && onRestoreInstanceState(Bundle)

[Sahil Verma]

I've had this same problem too and actually posted to the mailing list a few 
weeks ago but got not responses:

https://groups.google.com/d/topic/android-developers/6GfbdsJIj9k/discussion

I was testing it on hardware by simply rotating the phone, changing the 
orientation and recreating the activity.  However, the problem occurred 
randomly for me; it was very hard to reproduce as instance state would be 
restored after most orientation changes.  On a handful of occasions, the 
instance state would be wiped out as my UI would display as if started anew. 
 I have no solution so far.  I did a search some time back on the Android 
issues list at Google Code to see if it was a known bug, but I found 
nothing.

One workaround would be to persistently store the state which you wish to be 
restored in onPause.  If the state bundles in onCreate or 
onRestoreInstanceState are not filled, you could restore from persistent 
state.

Re: [android-developers] Re: how do I change screen orientation from ADB or equivalent?

[Bill Napier]

Then again, I just tried it with the Nexus S and it doesn't work.  It may
work on devices with keyboards like Droid.  Here's how I tested it:

$ adb shell "monkey --port "
$ adb forward tcp: tcp:
$ telnet localhost 
Connected to localhost.
Escape character is '^]'.
flip open
OK
flip close
OK

And nothing happened on my phone.  It may actually work on a device that has
a flip out keyboard (G1 or droid for example), but I don't have one handy.

Re: [android-developers] Re: Android Debugger is DOG Slow

[Streets Of Boston]

I agree with you about the *simulator/emulator*. If you don't have an 
absolute stellar system (and even then...), the emulator can be very slow.
But Eric's problem is with an actual device, not the emulator and Google is 
acknowledging the problem with the emulator. 
And I haven't seen the issues that he's describing when debugging on his 
device.

[android-developers] Re: Running application in Portrait mode on HoneyComb

[jtoolsdev]

I'm seeing that too and there are other posts on the forum reporting
it.  It is either a bug or we need something extra in the layout
declarations or manifest. But screens that size aren't really
documented yet.  My splash screen is fine and when I select the button
to take me to the next one the entire screen, not just my app screen,
is upside down (including the title bar, icons, etc).

I'm running a 64-bit AMD three core machine with Ubuntu 10.04 64-bit,
4 GB memory.  The emulator comes up fairly fast (1-2 minutes) and is
responsive.

The good news is that you can run your app and them use DDM to attach to 
the simulator.  So for myself, unless I'm debugging the start up of my 
game, I run then attach later.   This issue was the main reason I added 
j2se/PC support to my engine.   Developing the bulk of my games on the 
PC is a huge win.

Right. And when you tried debugging it via Eclipse, instead of IDEA,
what happened?

If Eclipse is similarly slow, then we can proceed to try to figure out
what is unusual about your application or device, since this is not a
widespread problem.

If, however, Eclipse runs normally, then there's something Jetbrains
is doing that is causing particular difficulty with you, your app, and
your device, and you should take this up with Jetbrains.

[android-developers] How to Get List of all Devices Connected to the Same Wi-Fi Network

[Robert]

I'm relatively new to Network/Socket programming so I haven't dabbled too 
much into it.

As my phone is connected to a particular Wi-Fi network, I want to get a list 
of all other devices (phone, computer, or other misc) that are connected to 
the same network. One of the ways that I tried to accomplish this was this:

   Enumeration   address;
   Enumeration   nets;

   nets = NetworkInterface.getNetworkInterfaces();
   for (NetworkInterface netint : Collections.list(nets))
   {
  address = netint.getInetAddresses();
  for (InetAddress inetAddress : Collections.list(address))
  {
 Log.d(LOG_TAG, "Host name: " + inetAddress.getHostName() +
"   IP: " + inetAddress);
  }
   }

However, all I get is the phone's IP address and a loopback call with 
LocalHost. I get the same result with this code:

   InetAddress host = InetAddress.getLocalHost();
   InetAddress[] address = InetAddress.getAllByName(host.getHostName());

   for (InetAddress result : address)
  {
 Log.d(LOG_TAG, "IP Address:: " + result.getHostName());
  }


When trying to search for this, I've only come across how to detect multiple 
networks but not devices. Does anyone know of a way I can retrieve this 
list?

Re: [android-developers] Re: how do I change screen orientation from ADB or equivalent?

It looks like the "flip" command from the protocol that monkeyrunner uses
may do it for you.  It looks like it never got added to MonkeyDevice to be
exposed as part of the monkeyrunner API.

Thank you for your suggestions.  Closing IDEA and running DDMS still
results in a slow running app on the phone device.  In any event,
since absolutely nobody else seems to experience a debugging situation
that is painfully slow, I will have to unfortunately assume that some
aspect of my application (i.e. high level of network traffic, and high
level of UI updates popped off the background thread), is somehow
causing the ADB interface to get fried.  I have no problems with this
functionality without the debugger (IDEA, DDMS, whatever you want to
attach), but they pop up with the debugging session attached.

The other disadvantage that I have is that we have a very nice
simulation environment available to us on iOS, and the lack of which
on Android, coupled with these debugging problems, is making it
difficult for me to justify shipping my app on Android too.

Thank you,
Eric

If you have "virtually 0 experience with java", then you need to stop and go
learn Java. Randomly changing code samples without understanding the changes
you're making isn't going to get you very far.


> How can I make this code work?
>

To be perfectly frank: learn Java. This is a simple Java problem and
moreover has nothing to do with Android specifically.
Once you have a better grasp of the language you will understand why Eclipse
does not recognize "parseDouble".

I'll also suggest you learn to use Eclipse itself, for not only will it tell
you exactly what the problem is, but usually offers suggestions on how to
fix it and often does so automatically for you on the spot.

Good luck.

[android-developers] Re: regarding monkey runner Tool

[Bill Napier]

Hi,

I'm going to start taking the same support stance the other android devs on
this list take.  I can't answer private questions, but I can respond to
questions posted on the list.

In this case, you can just use the same device object each time:

device = MonkeyRunner.waitForConnection()
img1 = device.takeSnapshot()
img1 = device.takeSnapshot()
img1 = device.takeSnapshot()

I will warn you that this is very slow.  In my tests, the fastest I could
get was around 3FPS.

Debugging, apparently. Personally, I use neither of them much.

Just because *you* don't have anything like that activated does not
mean that the *IDE* is not doing something that might use debugging
interfaces that might be slowing things down. Clearly, something's
going on. And we need to determine whether that issue resides
principally in Jetbrains' code or Google's.

Right. And when you tried debugging it via Eclipse, instead of IDEA,
what happened?

If Eclipse is similarly slow, then we can proceed to try to figure out
what is unusual about your application or device, since this is not a
widespread problem.

If, however, Eclipse runs normally, then there's something Jetbrains
is doing that is causing particular difficulty with you, your app, and
your device, and you should take this up with Jetbrains.

[android-developers] Re: Android Debugger is DOG Slow

[Streets Of Boston]

At what point does your app start running slowly:
- Initially, don't start DDMS or Jetbrain or Eclipse.
- Run the app on your phone which is unconnected. Does it run OK or slow?
- Then connect your phone to your Mac through USB: Does the app still run 
OK?
- Then start DDMS (not Jetbrain or Eclipse). Check if DDMS 'sees' your 
connected phone. Does the app still run OK?
- In DDMS, get some heap info or examine threads running in your app? Does 
the app still run OK?
- Close DDMS and start Jetbrain. Does the app still run OK?
- In Jetbrain, in the DDMS view, connect to your device. Does your app start 
running slowly?
- Close Jetbrain.

The application is running on the device, not on my machine.  It is
slow on the device.  What does Eclipse vs. IDEA have to do with any of
this?  The debugging interface on the device is causing the
application to not perform well ON the device.  I do not have any

[android-developers] Re: Action bar through compatibility lib on 1.x, 2.x API

Thanks Mark, shall try it out. Is that example (on git) for 3.0 only
or would it work on pre-honeycombs with the compatibility lib changes?

Ok, I can supply some info, but I don't think it will help.  The
problem is with the debugger, not my setup.  That is why my post was
terse, prompting Google to get their act together.

I have a NexusOne device running 2.3.3 hooked up to my 8-core Mac Pro
via the standard USB cable.  I am running the debugger shipped with
Jetbrains IDEA, which connects to the standard Android ADB.  My app
fires off a background communication thread after log in, where a
variety of financial market data is shipped to the phone via a very
efficient package in real time, and unmarshalled and popped to the
screen on the UI thread.  The app and its paradigm is fully proven by
a shipping iOS app, which performs extremely well inside, and outside,
the debugger.  The Android app performs well outside the debugger.
When I run it in the debugger, it is painfully slow (seconds of delay,
not ms).  The only changing variable there is the debugger.  Period.
And again, I won't even mention the awful Android simulator, because
my app barely even starts up on that.

And as soon as you demonstrate proof that Google's the source of the
difficulty, I doubt you'll get any quibbles. However, casting blame
without proof is not going to win you friends.

You will notice that "Jetbrains" is not "Google", except perhaps via
some sort of encryption algorithm.

When you contacted your IDE vendor (Jetbrains) regarding your problem
with their product, what did they tell you?

When you tested your application in Eclipse -- to prove that the
problem is in Google's code and not Jetbrains' -- what did you find?

The one main difference between my setup and yours is that your use 
Jetbrains. I'm using Eclipse 3.6. Have you tried using Eclipse?
What is your performance if you just fire up 'ddms' (not Jetbrains or any 
other IDE) and dump the heap or take a look at your apps' threads?

[android-developers] Activity#onRetainNonConfigurationInstance vs Fragment#setRetainInstance

[Shri]

I have a WebView in my Activity which I want to reuse across config
changes so that the webpage does not get reloaded after every
orientation change. I can use
Activity#onRetainNonConfigurationInstance/getLastConfigurationInstance
for this. However, I have heard that Fragment#setRetainInstance is
better for this purpose. This does not seem correct if there are other
Views involved which should be recreated after a config change (eg.
TextView which should be recreated after a locale change so that new
string resources can be picked up). I could keep only the WebView in a
Fragment, and all other Views in the Activity, but then either
approach seems good enough.

Just checking that Activity#onRetainNonConfigurationInstance/
getLastConfigurationInstance are not considered to be bad practice
going forward. 
http://developer.android.com/guide/topics/resources/runtime-changes.html
only mentions these apis anyway, not Fragment#setRetainInstance.

Thanks
Shri

The debugger is not a monolithic thing - many things can go wrong.
Your USB connection could be fried.
You could have faulty installation of Eclipse that breaks the debugger.
You could be calling a function that sleeps for 1 second at a time if the
debugger is attached, for all we know.

 Oh, sorry, I think you didn't get the previous email, where this was

Perhaps, I've had that happen once or twice, but typically my development
environment runs pretty quick, even on emulator.  I can notice some
difference when using the debugger but not noticable enough to cause
problems (how big is your app?  Probably not very, so you shouldn't see
problems either).

And right, some of the Google developers are on this list, and I'm sure
they'd contend what you're saying.


>

- Eric


Ultimately, I'm sure people would be glad to help you: typical use of the
debugger is not noticeable enough  to cause development issues, if you're
having that much trouble something is probably wrong in your setup or app.
 But you'll first have to give a detailed description of what code causes
problems, how you've diagnosed it (i.e., I started up emulator and broke at
line 232 of this file, function presented here, and my build set is, etc...)
However, insulting Google makes you look unintelligible (I'm guessing that
calling it a "simulator" doesn't win many points either.)

So if you'd like more assistance with the matter please try again with more
detailed code and build environment description.

Kris

P.s., you should have expected bad responses if you go on a random user
group and say (essentially) "this is bad, you suck."

[android-developers] ANR Camera Button Long Press Event

[Pandi k]

Hi,

I have an issue in camera button long press event.

Issue :
When I press and hold camera button, multiple times onpause is getting
called in applicaiton.
Is this expected behavior? and also my camera getting stop preview and start
preview. After some times, ANR coming.

Some times, onpause is not getting called and at this time, camera works
fine. no stop preview called from on pause.

Which one is correct in above two behavior ? or both?

How to take this to solve and any ideas

Thanks U...

Regards,
Pandi

In my experience, apps run somewhat slower in the debugger, but not by much. 
It is certainly not 'utterly unusable' slow.
If you do experience a very very slow performance while debugging, it may 
help us answer or solve your problem to describe what your setup is. Maybe 
some issue in the USB communication on your dev-environment? Maybe something 
else?

What else do you want to know?? When I run my app in the debugger, it
is unusably slow.  When I run it outside the debugger, it performs
satisfactorily.  The only changing variable is the debugger.  I have a
lot of network communication going on in a background thread.  When I
run the app in the debugger, the screens immediately become
unresponsive, whereas outside the debugger there is no noticeable
change in performance.

We can pretend the debugger is fast, like some of the follow up posts
have done, or we can discuss why Google can't provide developers with
a decent debugging environment (LET ALONE a simulator that is even
remotely usable).

This is a developer forum and most of us do expect that before you ask any
