Re: [android-developers] Re: Syntax error: Unterminated quoted string

[Dianne Hackborn]

"am" is the shell command that is run to launch an application.  So a bad
character got in that command line somehow...  though I'm not sure how that
could be, I think the main thing that is used there that comes from the app
at all is the manifest package name.

Re: [android-developers] Re: TransitionDrawable with different sized bitmaps

[Dianne Hackborn]

You could write your own Drawable that keeps its size consistent across the
images and does whatever transition you want.  Or use a ViewFlipper to swap
between ImageViews.

[android-developers] MediaPlayer blocked(AudioFlinger write blocked) while playing animation

[quill]

Hi all,

I have a thread to play audio and animation together. It's a frame
animation. The drawable resources are in sdcard. When I play the
animation, I use a handler to send message to refresh images one by
one.
Here's my code:
final Handler handle = new Handler(){
 public void handleMessage(Message msg){
  super.handleMessage(msg);
  BitmapDrawable bmpDraw = new BitmapDrawable("sdcard/
anim/"+msg.obj);
  imageView.setBackgroundDrawable(bmpDraw);
  imageView.invalidate();
  if(msg.what < fileNames.length-1){
  sendMessageDelayed(obtainMessage((msg.what+1),
fileNames[msg.what+1]),50);
 }
 }
};
handler.sendMessage(handler.obtainMessage(0,fileNames[0]);
MediaPlayer mp = new MediaPlayer();
...//play audio

The animation performs fine, but the audio will be stopped when it
begins to play for seconds. From logcat I see AudioFlinger: write
blocked for 89 msec...

I don't use AnimationDrawable because there are many images in sdcard,
when I use addFrame(AnimationDrawable.createFromPath(...)) I got an
OutOfMemory Exception.

Am I doing the right thing? Can anyone help me?

[android-developers] Re: Changing application description shown in option list when multiple apps can do same job

[Kacee]

Ok..
But I have seen applications that do not appear with their package
name in the list created by intent (dont know what to call this dialog
box )
That means there is a way to atleast hide package name. Package name
looks bit ugly, I only want to show a meaningful string (eg. app
name ) that makes sense even to a layman.

Is there a way just to show app name or a single string text ?

[android-developers] Orientation change and setRender

[qwesthead]

I've a region on an activity that uses GLSurfaceView. When the
Activity is resumed, I call the setRenderer and then the content of
the screen. They work fine. But, the problem arise when I change
orientation (configurationChange.) Upon orientation change, I need to
change the layout. After orientation change, surfaceChanged is getting
called. However, even when I call GLSurfaceview.requestrender,
Renderer.onDrawFrame is not getting called.
What are all the things I need to do when there is an orientation
change.

Re: [android-developers] Re: Problem when coming back to activity after changing font in Galaxy S

[Suresh Chandra Pal]

Hi Simon,
You suggested to make activity singleton.
But is 'making activity' singleton not equal to single instance.
At a time I'll be having a single instance. and I dont want to do that.
Moreover mainly, I want a way which is acceptable according to android
concepts.
and if that is not possible then only I will have to do some trick.
But in any case I dont want my activity to be singleinstance or singletask.

That's why I want something android specific.

If I got you wrong then please explain your solution.

No, that's different.  No amount filled in means that they will see
pricing in US$.  I was referring to the checkboxes in the list at the
bottom.

I'm not going to pretend to be a guru, but here goes :)

It's a generic method:

public static final  List emptyList()

In the second call there is no way to determine the type of the generic
parameter, so you get a list of Object.

I can't find that binary, otherwise I would debug and wrap it and dump
the arguments it has to deal with. Any hint where this binary is
located? Any other debugging options I can possibly enable to nail
this down?

As you can see from the package I uploaded, the AndroidManifest.xml
seems to be alright.

Sorry for the wrong code, but the ActivityOne do not have a button, but is
starting ActivityTwo immediately in its onCreate() method. and this code is
creating problem.


@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Log.d("ActivityOne", " setOnClickListener()");
 Intent intent = new Intent();
intent.setComponent(new ComponentName("com.demo.backpress",
"com.demo.backpress.ActivityTwo"));
 startActivityForResult(intent, 1);
}

[android-developers] Re: regarding HTTPClient : How to get the HTTP request posted by the native browser

[Jens]

Apache - as in the HttpClient, org.apache.http.* or the web server?
Further - the browser in the phone typically doesn't use the apache
HTTP client library, it's JNI to WebKit.

The good thing is that you're not going to be able to sniff either
without building your own firmware and flashing the phone.

Hi everyone,

there is no ldd for android available in the ndk. is it available

[android-developers] Problem when dealing with multiple screen sizes

[lou]

Hi !
I have some problems when dealing with different resolutions and sizes
of screen : my goal is to display an image in a square which is draw
in my background picture.
I have a main RelativeLayout which is filling the entire screen :

http://schemas.android.com/apk/res/
android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="@drawable/my_background">



In my background picture, there is a square ( for example at 10px from
the left and 40px from the top of the picture ). I want to display the
ImageView my_imageview IN this square.
In my manifest :






I tried to set my_imageview parameters like that :



But even with 3 types of drawable ( hdpi -> 1.5x, mdpi -> 1x, ldpi ->
0.75x), the imageview is not always displayed in the square.
For this  example :
- HVGA - MDPI : OK
- HVGA - HDPI : the imageview is underneath the square
- WVGA - HDPI : the imageview is a little over the square
- WVGA - HDPI : the imageview is a lot over the square
I also tried to set the layout_marginTop and the layout_marginLeft
three times ( values-small, values-normal, values-large ), but there
are still some bugs..

Is there anybody who can help me with that ?

Thanks, a lot !!
Regards

This is not possible from an SDK application, sorry.

If your interest is in creating custom firmware that has USB tethering
disabled, please visit http://source.android.com and use the support
resources found there.

Re: [android-developers] Can I change appwidget-provider XML 's android:initialLayout? How to do?

Just use your desired layout on the first onUpdate() call of your
AppWidgetProvider. You cannot literally modify android:initialLayout,
or anything inside of a resource, at runtime.

[android-developers] appwidget setOnClickPendingIntent not always working

[biokys]

Hi, I have an issue with my appwidget. It has really strange behaviour, 
because when I add widget to desktop it *not always* become clickable, even 
i defined setOnClickPendingIntent. On different phones it has different 
"successfull install ratio".

Thank you for your help

public class BasicWidget extends AppWidgetProvider {


private static final String LOG_TAG = "WalletWidget";

@Override
public void onUpdate(Context context, AppWidgetManager appWidgetManager, 
int[] appWidgetIds) {
Log.d(LOG_TAG, "onUpdate(): ");
context.startService(new Intent(context, UpdateService.class));
 }
 
public static class UpdateService extends Service {
@Override
public void onStart(Intent intent, int startId) {
RemoteViews updateViews = buildUpdate(this);

ComponentName thisWidget = new ComponentName(this, BasicWidget.class);
AppWidgetManager manager = AppWidgetManager.getInstance(this);
manager.updateAppWidget(thisWidget, updateViews);
}

[android-developers] Re: NFC Secure Element

[Martin]

Hello Michael,

here are the information I promised you yesterday.

Reader: Omnikey 55x3
Software: HID Reader Utility Version 4.0.0.0

Key:  it works for each sector.

This is what we found in the api:

// The well-known default MIFARE read key. All keys are set to this at
the factory.
// Using this key will effectively make the payload in the sector
public.

 public static final byte[] KEY_DEFAULT =

  {(byte)0xFF,(byte)0xFF,(byte)0xFF,(byte)0xFF,
(byte)0xFF,(byte)0xFF};

I checked the UID of the SecureElement, which I can get by calling the
getSecureElementUid() of the NfcSecureElement class via reflection.
And I also checked the sector 00 block 00 of the emulated MiFare card
with our external NFC reader to get the UID. They match!

Do you think it is possible to read/write data with APDU commands?
There is a hidden method in the NfcSecureElement class called
exchangeAPDU.
public byte [] exchangeAPDU(int handle,byte [] data){...}

I have tried some commands, which I found on page eleven at the
following pdf document:

http://www.nfc-reader.com/NFC-smart-card-reader/ACR122-API-Manual/API_ACR122.pdf

But I always get back 6E 00.

Best wishes!

Martin

Imran,

Any debug info?
Listing of your doInBackground() perhaps?

Are you saving the whole 10MB of text into memory or do you save it to
a file via some buffer?

Thanks for tracking down the source :-)

Since I only get one or two of these a week, I guess it's a SDK/device

[android-developers] Re: Appwidget set background and set background transparency/alpha

[String]

Assuming his code is similar to mine, it's a simple matter of implementing 
the color picker (from the source link) and then passing the selected 
colorValue through this call into the widget (from earlier in the thread):

RemoteViews.setInt(id, "setBackgroundColor", colorValue);

Is there some additional explanation needed?

[android-developers] Multiple markets, one purchase?

[Adam Ratana]

I've put my very modest apps in Amazon App Store now, and I've just been 
thinking about this, and musing about Amazon's future strategy, complete 
speculation:

- if Amazon is planning its Android tablets not to have the official google 
seal of approval, and not have android market (similar to what almost 
happened with motorola/skyhook), this could be the reason for their own 
curated market
- Someone's purchases on Android Market thus will not be installable on such 
a device?
- The more secondary markets to Android Market, the more this becomes an 
issue for the consumer and a potential nightmare for google?
- If someone buys a piece of software, ideally it should follow them from 
device to device (iTunes, current Android Market, the "cloud" model), this 
may break that
- If Amazon market will always be available on google devices (could be in 
question), but the same is not true for Android Market, wouldn't consumers 
then want to stick with Amazon App Store?

Just wondering what other peoples takes on this are and if it is a concern 
to them?  Or if anyone has insight into this sort of thing?  I doubt Amazon 
would attempt devices without the Android Market, but if there's a critical 
mass of the high quality apps in Amazon App Store, perhaps they would.

Re: [android-developers] Re: Multi-touch pointer ids on Sony Xperia Play & spurious ACTION_DOWN events

[Leigh McRae]

Thank you for taking the time for such a great reply.  I have couple of 
comments still though.


On 5/19/2011 3:35 AM, Jeffrey Brown wrote:

Some tips:

1. Use MotionEvent.getActionMasked() and MotionEvent.getActionIndex()
to retrieve the masked action and changed pointer id respectively.
This will remove the need for your own masking and shifting code,
which is currently using deprecated constants.
I'm targeting min sdk of 7 (5 actually it it seems to have been 
misplaced) and this is level 8.

2. Your code for ACTION_MOVE contains: "ptrId =
event.getPointerId( index ); if ( ptrId>= 0 ) { ...} ".  The pointer
id returned by getPointerId will always be>= 0 so you can omit this
condition.

3. You need to be more careful in your handling of ACTION_CANCEL.
When ACTION_CANCEL is received, you should reset the state for *all*
of the pointers you think are down.  So you should keep track of which
pointers you think are down, loop over them and cancel them all.

Something should be added to the docs about this then.

4. Before handling ACTION_DOWN, you should do the work of canceling
all pointers you think are down.  If everything is working properly,
then there shouldn't be any pointers down.  However, if your code did
not receive the matching ACTION_UP or ACTION_CANCEL from a previous
gesture, it's possible that some pointers got *stuck* down.  So you
want to clear those out before you start handling the new pointers.
I get a down event for one finger, say it lands on my virtual gamepad.  
The user holds that finger down and slides the control around to make 
their unit move.  Now they put another finger down on a fire button 
while the previous finger is still on the gamepad.  At this point I 
think you're suggesting I clear the first finger on the gamepad.  It 
doesn't sound right.

5. The sleep() is entirely unnecessary.  It is just making the input
latency of your game worse.  Remove it.  The framework already
throttles move events for you.
I'm all for this but every game engine I have found for Android does 
this, even Replica Island.  How sure are you of this?  Keep in mind that 
my game needs to run on older 2.0 that might suffer from this problem.

follow.  My game needs to track one touch for the game pad and then at
least another for the fire buttons.

Currently my game is broken on the Xoom and I'm assuming it's because
of the same problem this thread talks about.  I can make the changes as
others have suggested by mapping but I still have some issues.  I'm not
sure if I handle Cancel correctly.  It's a really large concern as my
game captures pointers so I know whether the finger was over the button
it pressed when it was released.  I really need to get matching events
or buttons will get stuck.  It's not so bad when IDs are 0 or 1 but when
they cycle to 15 it will be harsh.

As you can see I have added some sleep code below but I'm not sure if
it's needed.  It's really hard to know what to do here as people
complain about unresponsive controls but they work fine on my phone and

Yes, really. Just because you're making an Android App does not
automatically make every question you have on it it appropriate for this
list.

These are the key things you mentioned in your post:
- OAuth
- Twitter
- Eclipse
- 401 Error
- Your Twitter Account
- Twitter-registered application with key & secret & callback URL

No a single mention of Android or the Android SDK. So yes, really, an
Android Twitter app question has nothing to do with Android Development if
the questions are about connecting to Twitter and not with using the Android
SDK to make the app.

Much like a question about an Android Facebook app should not be posted here
if it's regarding connecting to and using the Facebook API.

Again: you got this sample project from "Marakana"? Sounds like it's their
problem - ask them.

[android-developers] Re: Java Guru needed -- compiler bug?

[Streets Of Boston]

Welcome to the wonderful world of generics.

The emptyList method is defined as follows:

public static final  List 
 
emptyList()

With the statement Collection s = Collections.emptyList(), the 
compiler knows (because of the declaration of 's'), what the type for 'T' 
is. It is 'String'.

And i'm still not sure why the compiler can't pick up the same info from the 
's' parameter declaration of the method 'method'.

However,  you can fix this by changing the method signature just a bit:
private void qqmethod(Collection<*? super *String> s)

[android-developers] FragmentPager component?

During the Android 3.0 UI design talk on IO 2011, it was mentioned

bit more about this component, when'll this be released and what'll it
be able to do? I'm quite curious, because it awfully sounds something
that I'm working on right now. Is it about some kind of left-to-right
fragment paging mechanism that's used in the Honeycomb Gmail app?

[android-developers] Re: startActivityForResult

[kypriakos]

Ah sleep is good ...

Ok revisiting this I can see the wrong path I went down to ...

I built a servlet for the ijetty web server that launches an Activity
once
a particular remote request comes in. The ijetty code provides the
AndroidContext
in all servlets through:

Object o =
config.getServletContext().getAttribute("org.mortbay.ijetty.contentResolver");
android.content.ContentResolver resolver =
(android.content.ContentResolver)o;
androidContext =
(android.content.Context)config.getServletContext().getAttribute("org.mortbay.ijetty.context");

So while implementing the methods for the servlet I got carried away
with the fact that I had
the appropriate context available and used the Context's startActivity
method and the Intent object to launch
the Activity (after I declared it in the ijetty's AndroidManifest). I
kept looking in there for the startActivityForResult
I needed a bit more reading on the difference between the two
startActivity methods across two different classes in the inheritance.
The code snippet I sent out does work but I cannot of course use the
startActivityForResult.
Up to this pt I was having the launched activity save the results in a
file and then had the servlet poll for
them but that's not an ideal solution. The servlet itself implements
HttpServlet so by not being an Activity
I could not see how any callback to it would be possible - what do you
think?

@Kostya
> If this case, use a broadcast, a pending intent, or a handler message (just
> some of the options) to send/receive the result.

I agree with that but I need to figure out how the servlet fits into
this. I could launch
the activity as a service.

> Oh, and I see that the intent you're trying to start is for a service. Using

Where do you see that? The intent I am starting is an Activity class.
Can you explain please?

If you could take a step back, why are you using Jetty in the first place?
Sounds interesting and all, but unless this is a research project, what
have you got to gain by running a servlet engine on your phone?

This has some interesting stuff on Java's type inference for generics:

http://www.angelikalanger.com/GenericsFAQ/FAQSections/TechnicalDetails.html#Topic7

My impression is, there are several special cases where the type is 
inferred, one of them being assignment.


The page has examples where type inference doesn't work, and suggests 
using a temporary variable to help the compiler, just as was discovered.

Correct. The layout supplied to the RemoteViews constructor does not
have to be the same layout supplied to android:initialLayout.

[android-developers] Merchant Sales Report Issues

[polyclefsoftware]

I'm happy that Google has now added more detailed sales reporting to the 
Android Developer Console. Reconciling my payouts to partners and sales 
taxes was a nightmare before. 

However, there seems to be an issue with the reports from Jan 2011 and all 
months prior. 

Many of the fields have entries such as:

DEFAULT_HARDWARE
DEFAULT_TITLE
DEFAULT_PACKAGE

instead of properly listing the device name, app title, and app package. 

Also, the number of sales is way off. Has anyone else noticed this? If there 
is a more appropriate forum to note this issue, or a place to report bugs, 
please point me to it. Otherwise, could someone from Google respond to this? 
Sales reporting is one of the biggest headaches with regard to running a 
small business based on Android development.

As I wrote, you cannot change appwidget-provider XML, or any resource,
at runtime.

In your RemoteViews constructor, use the layout you want.

[android-developers] OpenGL ES 2 support in emulator?

[Thomas]

I'm wondering if Google has any plans to include OpenGL ES 2 support
in the Android emulator at some point in the future?  ES 2 is becoming
increasingly more important as users upgrade for 2nd generation
Android phones and the percentage of 1st generation phones (that do
not support ES 2) diminishes.  I'm considering not supporting earlier
versions at all (as of now, they are less than 6% of the total market-
see http://developer.android.com/resources/dashboard/platform-versions.html).
The only solution at the moment is to either compile OpenGL ES 2 code
straight to a desktop OS (provided you're only using features
compatible with standard OpenGL) or to get a 3rd party OpenGL ES 2
emulator.

Re: [android-developers] FragmentPager component?

[Dianne Hackborn]

It is something I have been working on.  I don't know when it will be out to
be used, but it will likely still be quite rough at that point.  The code is
not used by anything released at this point.  It lets you do interactions
like the swiping between panels in the news and weather app...  though it
won't include the tab part any time soon.

[android-developers] Appwidget RemoteViews copy

[Niall]

Hi all. 

I've a quick question pertaining to remote views. 

Is it safe to keep and maintain a copy of the last RemoteViews that was used 
for updating the appwidget? I have a status message that is updated 
regularily (more so than the rest of the widget). Suppose I have something 
like... 

This updates the views (this is called before manager.updateAppWidget( 
ids[i], remoteViews ); )

  void updateAppWidgetFunction( Context context ) {
RemoteViews remoteViews = new RemoteViews( 
  context.getPackageName(),
  R.layout.main );
  
// Set all the views stuff

lastRemoteViews = remoteViews;  // lastRemoteViews is a static private 
member of the class
  }


And I have a method that updates the status message like so:

  void updateStatusMessage( String str ) {
RemoteViews remoteViews = null; 
if ( lastRemoteViews == null )
  remoteViews = remoteViewsWithIntents( context );
else
  remoteViews = lastRemoteViews; 
  
remoteViews.setTextViewText( R.id.textview_status, str );
refreshWidgetViews( context, remoteViews );
  }



Is this good practise? Or should I make a means of specialising the 
updateAppWidgetFunction to update the status message only?

[android-developers] Re: Why ImageView doesn't show up inside ScrollView

[Frank]

Thank you, Mark,  for the reply.

For of all, I am pretty new to Android and my code is by no means
doing things in the most meaningful way. :)
Before answering your question, can I ask does using
LinearLayout.LayoutParams prevent it from working? I tried to comment
it out, but it still doesn't work.

In fact, this is just a trial code. What I really want to do is to
tile a ViewGroup with a whole bunch of ImageViews. I want to specify
the absolute location and dimensions of each ImageView inside the
parent ViewGroup. However, it looks to me that I cannot do this. I
found there is AbsoluteLayout, but it is deprecated. So do you know of
any option to achieve this?

Thank you very much.

Where do you see that? The intent I am starting is an Activity class.
Can you explain please?

You class is named ...Pic2*Service*Impl, so I assumed it was a Service. 
If it's an Activity, well, so it is - you know your code, whereas I 
could only guess from the class name :)

Quite possibly.

Just call addView() with the child View. Note that I have never tried
populating a ScrollView from Java (most people use XML).

Write your own ViewGroup.

Or, don't use widgets at all, and draw on the Canvas, the way 2D games do.

Bear in mind that there is a massive range of screen resolutions
(based on size/density), which is why AbsoluteLayout is deprecated, as
it does not lend itself to creating UIs that work well on everything
from a 3" phone to a 10" tablet to a 42" TV.

Haven't read carefully all the responses but just a quick note:

It's not a good idea to declare the request code as a local variable, I
usually declare them as constants because you'll need it in the
onActivityResult method :)

Re: [android-developers] Appwidget RemoteViews copy

[Kostya Vasilyev]

Keeping the same RemoteViews object and repeatedly adding more 
operations will cause the copy in your process to get bigger and bigger, 
and the actual updates in the launcher process to get slower and slower 
over time.


The basic pattern is really simple:

rv = new RemoteViews ()
rv.setSomethingOrOther()

if (needStatusMessage) {
rv.setTextViewText(..., "Loading 100TB, 0.0001% complete...");
}
else {
rv.setViewVisibility(..., View.GONE);
}

appWidgetManager.updateAppWidget(, rv)


On the other hand, if you just want to reuse the remote views object 
once, that's probably fine.  But I don't think it's really worth the 
risk of accidentally breaking something.

[android-developers] Re: ListPreference.getSummary

[String]

Reviving an old [degenerate] thread, rather than creating a new one...

I've been getting occasional UnknownFormatConversionException error
reports in my Dev Console, and had no idea what they were from. Today
I think I've figured it out, because it's occurring reliably on my
Honeycomb device.

Turns out it happens when there's a "%" character in a string resource
used as a label in a PreferencesActivity. Seems that the system thinks
it's going to be a format specifier, tries to evaluate it as such,
fails, and then falls over. But in my case, it's not; I'm letting the
user specify a pref for transparency of an AppWidget, with options
like 25%, 50%, etc.

I'm not sure how to fix it yet, and I'm open to suggestions. I tried "/
%", like you do for an apostrophe char, but that didn't work at all.
Tried "%" (the entity for "%"), but apparently that gets evaluated
too early, and the same problem occurs. If all else fails, I could
just use "percent", but that's kind of hokey.

Any other ideas?

[android-developers] Re: How to load resources like texture images & sound files in native code?

The example basically involves loading up the PNG Java side using the

Which part is giving you trouble?  I'll guide as best I can.

Re: [android-developers] Re: ListPreference.getSummary

[Kostya Vasilyev]

Percent character in String.format() is obtained by specifying "%%" (two 
percent signs).


http://download.oracle.com/javase/1.5.0/docs/api/java/util/Formatter.html

( search for "percent", where it says "The result is a literal '%'" )

But I bet you already knew that :)

On the other hand, this requires that the string pass through Format to 
produce the single percent sign, which it doesn't for stock Android source.


How about you create a subclass of ListPreference, override getSummary, 
and return whatever you need, skipping the call to String.format(), 
effectively undoing the CM change.


As a side note, that's custom firmware for you. Users probably love the 
feature to see the current list entry in every application, but it seems 
so insignificant compared to a possible crash. And no try/catch block in 
the modified version either...

Reviving an old [degenerate] thread, rather than creating a new one...

I've been getting occasional UnknownFormatConversionException error
reports in my Dev Console, and had no idea what they were from. Today
I think I've figured it out, because it's occurring reliably on my
Honeycomb device.

Turns out it happens when there's a "%" character in a string resource
used as a label in a PreferencesActivity. Seems that the system thinks
it's going to be a format specifier, tries to evaluate it as such,
fails, and then falls over. But in my case, it's not; I'm letting the
user specify a pref for transparency of an AppWidget, with options
like 25%, 50%, etc.

I'm not sure how to fix it yet, and I'm open to suggestions. I tried "/
%", like you do for an apostrophe char, but that didn't work at all.
Tried "%" (the entity for "%"), but apparently that gets evaluated
too early, and the same problem occurs. If all else fails, I could
just use "percent", but that's kind of hokey.

Any other ideas?

android.preference.ListPreference.getSummary(ListPreference.java)
It happens only on Cyanogen's firmware when there's "%" symbol in
ListPreference's summary.

If u will open ListPreference.java from Froyo's sources u wouldn't
find method ListPreference.getSummary, so it looks like ListPreference
uses base method from Preference.java:
  public CharSequence getSummary() {
 return mSummary;
 }
And javadoc's from eclipse it confirms that:Returns the summary of
this Preference.

Ok, now let's open ListPreference.java from Cyanogen's sources:
   public CharSequence getSummary() {
 final CharSequence entry = getEntry();
 if (mSummary == null || entry == null) {
 return super.getSummary();
 } else {
 return String.format(mSummary, entry);
 }
 }
It look's like it's Cyanogen's feature (only 8 bug reports from>3000
users), but let's go 
tohttp://developer.android.com/reference/android/preference/ListPrefere...
Returns the summary of this ListPreference. If the summary has a
String formatting marker in it (i.e. "%s" or "%1$s"), then the current
entry value will be substituted in its place.

WHAT IS GOING ON HERE???
Can someone explain how *exactly* getSummary works?

No, I hadn't thought of using "%%". That works, thanks!

FWIW, this is happening in stock Honeycomb, not CM as the OP was
experiencing.

[android-developers] Unlock thing

[Renan]

I have a running android Service. It runs even on the lockscreen, and
I want it to somehow Unlock the lockscreen.

How can I interfere with the lockscreen activity or whatever the
lockscreen is, to unlock it...

I want my service to Unlock the lockscreen, just like if the user
slided the unlock thing.

How might I do this?

Re: [android-developers] NoClassDefFoundError thrown when an Android project references Eclipse project where project layout is set to "project folder as root for sources and class files layout"

The only possible workaround is to export the referenced project as a

I've seen the bug you filed and will be looking at it to see what's up
in our builder (thanks for providing a test project too!)

[android-developers] how to generate ID's for dynamic radio buttons

[jotobjects]

I am generating RadioButtons in code and adding them to a RadioGroup.
Seems like I need ID values to be able to use check(id) and so forth.
The bug I have now is that calling RadioButton.setChecked(true) does
not uncheck the already checked button.

For creating ID's in code can I just use  1,2,3,... id values or
whatever for the RadioButtons to work correctly with check(id)?

Hi Mark,

If I can tile a ViewGroup as I planned originally, I can tile beyond
the visible region. Then when it is scrolled, Android can just quickly
scroll in the new tiles (with whatever hardware acceleration it can
use). If I use Canvas, I need to redraw the entire Canvas using the
tiles (basically, copying tile buffer onto Canvas using drawBitmap),
would this be slower than the first option, because it cannot benefit
from the possible hardware acceleration? This is just my concern. Your
expertise is highly appreciated!

Thanks,
Frank

[android-developers] Re: how to generate ID's for dynamic radio buttons

[jotobjects]

Adding more detail to question - the source for CompoundButton shows
that findViewById() is used to find the currently checked button.  So
that means ID's I assign to these buttons must be unique in the
current View hierarchy.

Does anyone have a suggestion on generating unique View ID''s at
runtime?

Is there another mechanism on b.android.com to subscribe to an issue
without voting for it?

There's no question that it's fairly pointless, at least in the way
the core Android team is using the issue tracker. However, voting and
subscribing appear intertwined. Some issues, like this one, I simply
want to be notified regarding their progress or posted workarounds.

Re: [android-developers] Appwidget RemoteViews copy

[Niall]

See. The problem is that I generate a table (with nested ListViews) and 
display it on the appwidget, and the elements of the table (as well as the 
buttons) have on intents tied to them when a user presses on a place of the 
table. And if the orientation of the phone changes (which isn't beyond the 
realms of possibility) with the simple update that you pasted above the 
table I generated and the intents associated will neither be shown or be 
clickable... or at least I am lead to believe they won't. 
Am I correct in this assertion?

if you plan to build your own SDK, delete the line "usb0"

disable the usb tethering.

That would be kind of pointless, as the SDK does not get installed on the 
device.

Re: [android-developers] Appwidget RemoteViews copy

[Niall]

I should explain better. 

A user presses a refresh button (or an alarm service triggers the same 
effect) on the appwidget. I want to tell the user that the system is 
refreshing so they know the widget's doing something. But I want to tell the 
user that it's happening immediately. So I need to update the status message 
(it's always shown) and update the appwidget, and then trigger the refresh 
task which might take 10 seconds or so (downloading info from the net). 
That's really the only time I need to do what I explained. 

The best way I can think about doing it is by saving the previous 
RemoteViews that I generated when generating the table layouts. Does that 
make sense? 
I *think* it should be safe...

1 - Use your debugger.
2 - Figure out what is null.
3 - Make it not null.

First set any value in edittext then u can get value .

   1.  EditText IPInput = (EditText)
findViewById(R.id.ip);
iPinput.setText("Value inserted successfully");
   2.  IPInput.getText().toString();
System.out.println(ip);
   3.  System.out.println(IPInput.getText().toString());
