Yep, the user has just replied that he has a Galaxy Nexus and it doesn't 
have an SD card of course :(

Can anyone think of another reason why the Widgets are being removed from 
the list when deleted from the homescreen?  He says that the application 
still appears in the list of apps, so he isn't accidentally uninstalling.

I'm a bit stuck on this one.

 Hi all,

 I want to know about Encryption features of android like ENCRYPT

 how we can encrypt

See below.


 1- Phonebook entries
 2- Files stored on the sd card


It encrypts the whole filesystem, so everything is encrypted. If the
SD card is a separate physical device, it won't be encrypted,
but check the docs for details.

 I need complete details so that i can go further in this direction if
 anyone has some links related to information or any help is

You have to add the guava-r07.jar library, then it works.

You find this jar on the web or in the android sdk at
android-sdk-path/tools/lib/guavalib.jar

Re: [android-developers] AppWidgets Disappearing from list in ICS


Have you already asked him to reboot the device, just in case?

I've had similar reports (not on ICS) where rebooting helped.

As for the memory card and ICS - the original message didn't say it was 
a Galaxy Nexus, and there are already ICS - based ports of Cyanogen for 
a variety of devices where the user can move any app to external 
storage, even those explicitly having internal only in the manifest.

  No, it simply means you can't write code that tries to access internal C++

[android-developers] NullPointerException at MyService.onStartCommand ?

Occationally users report a NullPointerException Error at
MyService.onStartCommand() for some of my apps.
I never see this error when I try to debug the apps, and I wonder why
this happens.
I have studied the code both for the methods onStartCommand() and
onCreate() for the services in question, but I seem unable to find the

[android-developers] Strange webview problem

2011-12-15 Thread Neilz

I wish this was an april fool joke, but no. This is nuts.

I have a certain piece of text which when I load it into a webview, it
displays fine. If I pause and then resume the activity, the webview is
blank. Usually it happens immediately on the first resume, sometimes
it takes a few goes.

Once it's happened, no webviews in my app will display anything at
all. Completely unrelated activities have blank webviews.

The offending text is this:

webView.loadData(ulli3/liliOrange/liliT-Mobile/
liliVirgin/li/ul, mimeType, encoding);

I've started with a very long page of HTML and whittled it down to
that line. It breaks my webview. If I edit the line at all, it loads
fine every time. I've played with all the webview settings too.

Please put me out of my misery, what's happening here?

   String[] TempTempstr = Tempstr[x].split(@);
   cb.setText(TempTempstr[0] + ,  + TempTempstr[1] + ,  +

[android-developers] Re: including/excluding conditional code in different builds

2011-12-15 Thread hhenne

In java you don't have macros (#ifdef) = compiler instructions. In
stead you have to make a plain java function, which will do the same -
the only difference is, the macro will not generate a call instruction
- so it's more efficient.
Personally I use it a lot. It is nice, to be able to switch off
technical or business features by just changing a flag from true to
false. You can use it for having more versions for different
environments, for searching for nasty bugs, or for handling different
versions - alternative to branching.

[android-developers] WebView and ResponseCache

2011-12-15 Thread ydm

Hello, all!

The ResponseCache class is a great tool for performance improvement
and bandwidth consumption optimization. Anyway, I'm using it in a
slightly different way -- to create something like Resource API (which
will be most probably open-sourced soon) to serve app content when
device is offline.
I'm facing two showstoppers.
First, is there a way to force the WebView to use the very same
ResponseCache for its URLConnections. Sadly the WebView manages its
own cache subsystem and its requests do not pass trough the
ResponseCache.
Second, is there a proper way to see the remaining free space on hdd/
sdcard? What I'm doing now is querying the df Unix utility and parsing
the output, which is kinda hacky and surely not the best way.

I'm using Android API level 7 (2.1).

Thank you for your attention! Best!
Y.

for (int i = 0; i  sss1.lenght(); i++)
if (sss1.charAt(i) = '0'  sss1.charAt(i) = '9')

int start = sss1.indexOf(sss0);

Hope it helps.

Thank, Kostya.

So, you mean that I should return START_STICKY_COMPATIBILITY to avoid

But the actual problem then probably lies somewhere else, which may

It could be some Exception. Why are they not registered?

I have two separate apps (released long before in-app billing) and they are
always updated together, at the same time with the same release notes, so
users know what new features have gone into the full version. Most
importantly, using an Android Library Project, I only need to maintain one

Perfectly valid option and it's a standard model most users understand.

  How many times have you created a new CheckBox?
  Now how many times are you adding a check box to the layout?

Though there was a thread on this list a few months back that was a
fairly passionate argument as to whether or not Android should include
precompiler setups by default (the response was an overwhelming no,
with the implication that if you need it you could go find it yourself
and add it without too much trouble).

[android-developers] Showing DialogFragments crashes ICS

2011-12-15 Thread Flávio Faria

After the Fragments API being released, I started porting all my
deprecated dialogs into DialogFraments using the compatibility
package. Everything was working well, until I notice that my dialogs
are causing crashes to ICS only:

E/AndroidRuntime(  883): java.lang.IllegalStateException: Can not
perform this action after onSaveInstanceState

My dialogs are shown on AsyncTask.onPostExecute() in order to show an
http response to the user. After diving into the problem, I got the
conclusion that this exception only happens when the Activity is
paused or stopped, and it does not happen on other versions of
Android. I've tried using commitAllowingStateLoss(), but it doesn't
help, since the exception is thrown on DialogFragment.show(). Here's
my code for the DialogFragment:

http://pastebin.com/hPhPQ8Aq

Is it wrong to create dialogs on paused or stopped activities? How can
I assert that my activity is resumed before showing a dialog on this
case?

[android-developers] Slow scrolling in Date/TimePicker using Holo theme

2011-12-15 Thread Dirk Vranckaert

I'm trying to build an activity on which the user can change a certain
date and time.
So I created an activity and a layout file, in the layout file
(containing more than just the date and time picker, you can see it
beneath) i define the date and time picker.
The application android 2.1 compatible, but I compile it under 3.2 so
that I can use the Holo theme in the entire application.

Running the application on 2.1 till 3.1 gives me the old-style date
and time picker, where you can type the value or press plus/minus.
Running on 3.2 or 4.0 gives me the new Holo styles date and time
picker, where you can also type or press plus and minus. So far so
good. But with the new style you can also scroll on the day, month,
year, hour and minute, but for some reason that doesn't quite work in
my application! What it does: I try to scroll down (let's say minute
is on 49, I want to change it to 30). It starts scrolling, and the
first pixels are just fine and smooth. But then it blocks and
everytime i initiate a scroll-swipe again it scrolls only a few
pixels. To scroll from 49 to 48 I have to scroll 5 or 6 times... Not
really normal I guess.

I also use the DatePickerDialog in some cases, there scrolling goes
smooth as supposed to be.

So is there anything I forget to do when using a date and/or time
picker in an activity?

Attachments:

Here is my layout file:

ScrollView xmlns:android=http://schemas.android.com/apk/res/android;
android:layout_width=fill_parent
android:layout_height=fill_parent
LinearLayout xmlns:android=http://schemas.android.com/apk/res/
android
  android:layout_width=fill_parent
  android:layout_height=fill_parent
  android:orientation=vertical
!-- Content... --
DatePicker android:layout_width=fill_parent
android:layout_height=wrap_content/
TimePicker android:layout_width=fill_parent
android:layout_height=wrap_content/
!-- Content... --
/LinearLayout
/ScrollView

And here is the part of my activity where I set the values on the date
and time picker:
datePicker = (DatePicker) findViewById(datePickerId);
timePicker = (TimePicker) findViewById(timePickerId);

datePicker.init(part.get(Calendar.YEAR),
part.get(Calendar.MONTH), part.get(Calendar.DAY_OF_MONTH), null);
if (getAndroidApiVersion() = 13) {
datePicker.setCalendarViewShown(false);
datePicker.setSpinnersShown(true);
}

timePicker.setIs24HourView(true);
timePicker.setCurrentHour(part.get(Calendar.HOUR_OF_DAY));
timePicker.setCurrentMinute(part.get(Calendar.MINUTE));

Re: [android-developers] AppWidgets Disappearing from list in ICS

Ok, the user has responded to me with: - 

Ok I got the update then I did this
added a clock
removed that clock
went back to widgets, icon for clock still there
got as far as tapping add widget
got Unfortunately, Launcher has stopped.
clock widget now missing from widget list

So then i tried rebooting the phone, clock widget still missing
So I went through the same process with the bar widget but at the point 
where it
stops I remembered to click Report

So for some reason my widgets are causing the Launcher to crash (or the 
launcher is bugged), has anyone ever caused the launcher to crash when 
adding widgets?

I've asked him which launcher he is using, but I suspect its the default 
Nexus launcher.

I'll do some more googling armed with this extra info, but if it rings any 
bells with anyone please let me know :)

All the best,
Ash

[android-developers] openOptionsMenu not working on Honeycomb device

2011-12-15 Thread Royston

I have an app in which I select a theme of 
android:Theme.Holo.NoActionBar.Fullscreen. the app has a minim SDK of 11 
and a target of 13. I am avoiding the use of the ActionBar due to issues in 
the way this works on different sized devices. 

I am attempting to provide a menu button which simply does a call to 
openOptionsMenu. On certain device emulations this works as expected e.g. 
an ICS Large screen sized emulator. However, on other devices the menu 
button does nothing, the click is registered but no menu appears and no 
call is made to onCreateOptionsMenu or onPrepareOptionsMenu. There is no 
application crash, simply no menu. 

I see some discussion that on Honeycomb there are issues with  this and 
with the presence/absence of a title bar. Is there any known solution to 
this issue. I would add that there is no soft menu button displayed by the 
device so in these circumstances the users would be locked out of options.

Re: [android-developers] Re: NullPointerException at MyService.onStartCommand ?

Well, maybe you should return START_NOT_STICKY, or
START_REDELIVER_INTENT, or add an if statement checking for null - it
just depends on the service.

Read the docs, run your own experiments with DDMS, then decide what is
the right thing to do for your code.

The DDMS Perspective in Eclipse is under Window / Open Perspective /
Other... / DDMS. The Devices tab lets you terminate your own apps's
processes.

 There is a much better way to do this. I have outlined it in a prior

 Basically, you do not needconditional compilation. The *only* Java
 code which needs to change is the generated R.java file -- and even
 that you should be able to generate correctly, though I wasn't able to
 get it to work.

 It can all be done with an ant script. The manifest needs to be
 processed. It's helpful to process some resource files -- for example,
 to embed the version number, etc. XSLT is your friend here, it's much
 easier to manipulate XML than to deal with all the issues with
 preprocessing -- including completely screwing up line numbers, in
 most cases, but commenting out rather than omitting lines should avoid
 that!

 To avoid screwing up the debug cycle, I produce by default a dev
 version, which gives access to both free and pro functionality for
 test and debug.

Can you show us how you management these version?
Some piece of code... or a link to a full code will be wonderful.

longer... But could it be shorter?

Currently I do it every 5 Minutes with 0 Meters and I receive
sometimes 50 Locations in a minute.. it wait's and I get 10-20 Seconds
later the next, then 40 Seconds...

But it is definitely NOT every 5 Minutes or longer...

Re: [android-developers] AppWidgets Disappearing from list in ICS

Have you tried your widgets on the ICS emulator?

Does repeating the sequence reported by the user on a pre-ICS device
result in any warnings or errors in the logcat?

In general I agree that using a preprocessor in Java is a bad idea,
but I'm also flexible because of the weird changes that exist across
the many possible android builds running amok.. (i.e., in theory you
shouldn't have a hacky solution like this, and your design should be
neat and include interfaces which do things like check if certain
system features are available, but sometimes you just can't beat it..)

The docs say:

minTime the minimum time interval for notifications, in milliseconds.
This field is only used as a hint to conserve power, and actual time
between location updates may be greater or lesser than this value.

In practice this is just that, a hint, you can look through the
LocationManager implementation if you'd like to find out exactly why
this happening, but I wouldn't worry about it too much, what are you
worried about?

If you only need the location at very coarse intervals, have you
thought of using requestSingleUpdate, then waiting some long amount of
time?

Here you have much better control over the temporal distribution of
your updates.

(I'm assuming you're concerned about power usage..)

Re: [android-developers] openOptionsMenu not working on Honeycomb device

AFAIK, if you don't have an action bar, you don't have an options
menu. You will need to either add back the action bar or not use an
options menu.

 I am attempting to provide a menu button which simply does a call to
 openOptionsMenu. On certain device emulations this works as expected e.g. an
 ICS Large screen sized emulator. However, on other devices the menu button
 does nothing, the click is registered but no menu appears and no call is
 made to onCreateOptionsMenu or onPrepareOptionsMenu. There is no application
 crash, simply no menu.

 I see some discussion that on Honeycomb there are issues with  this and with
 the presence/absence of a title bar. Is there any known solution to this
 issue. I would add that there is no soft menu button displayed by the device
 so in these circumstances the users would be locked out of options.

 I have a certain piece of text which when I load it into a webview, it

 it takes a few goes.

 Once it's happened, no webviews in my app will display anything at
 all. Completely unrelated activities have blank webviews.

 The offending text is this:

 webView.loadData(ulli3/liliOrange/liliT-Mobile/
 liliVirgin/li/ul, mimeType, encoding);

 I've started with a very long page of HTML and whittled it down to
 that line. It breaks my webview. If I edit the line at all, it loads
 fine every time. I've played with all the webview settings too.

 Please put me out of my misery, what's happening here?

[android-developers] Partition confusion

2011-12-15 Thread Joerg Pleumann

Hello,

would someone from Google mind explaining the current strategy behind the 
various partitions? I'm a little bit confused.

- In the beginning /sdcard was used for external storage, but since you 
could not rely on the mount point across vendors, the proper way to access 
it was the Environment class (or the convenience methods in Context).

- Since 3.x an increasing number of devices use /sdcard for an additional 
internal storage that can not be removed. The docs have been reworded and 
tell me I now have to think about external storage in a different way. 
The Environment class only knows about the primary external partition.

- Some devices still come with a real SD card. That seems to be mounted as 
/mnt/sdcard2. Some even support USB Host and /mnt/usbdrive.

Now my questions:

- What it the proper way to access non-primary external partitions? Should 
I rely on the above mount points?

- What are those non-primary partitions actually used for? Can I only 
access them with a file manager? Are they scanned by the media service?

- Is there a plan to add a proper API that helps me deal with them?

Cheers
Joerg

Re: [android-developers] Re: UI like Youtube

For dynamic content on the bottom, you can:

- Override getView and check the item position (maybe not quite
religiously pure, but it works).

- Use an OnScrollListener to be notified of scroll state changes, wait
for SCROLL_STATE_IDLE and check what's visible

http://developer.android.com/reference/android/widget/AbsListView.html#setOnScrollListener(android.widget.AbsListView.OnScrollListener)

Or come up with something else, such as maybe subclassing the list

 2011/12/15 Kostya Vasilyev kmans...@gmail.com

 For dynamic content on the bottom, you can:

 - Override getView and check the item position (maybe not quite
 religiously pure, but it works).

 - Use an OnScrollListener to be notified of scroll state changes, wait
 for SCROLL_STATE_IDLE and check what's visible


 http://developer.android.com/reference/android/widget/AbsListView.html#setOnScrollListener(android.widget.AbsListView.OnScrollListener)

 Or come up with something else, such as maybe subclassing the list
 view, overriding onLayout and checking the last visible position after
 calling super...

:: shrug ::

Either your app has an immersive experience, or it does not.

Apps where you consider the whole screen to be yours (games, video
players, etc.), you simply have to make your menus yours as well.
Games have done this for quite some time, eschewing menus and
PreferenceActivity and the like to keep their immersive experience
consistent.

Apps that do not require this level of experience customization should
be using the action bar, for consistent behavior across apps.
Avoiding the use of the ActionBar due to issues in the way this works
on different sized devices, IMHO, is not a valid argument.

I wish this was an april fool joke, but no. This is nuts.

I have a certain piece of text which when I load it into a webview, it

it takes a few goes.

Once it's happened, no webviews in my app will display anything at
all. Completely unrelated activities have blank webviews.

The offending text is this:

webView.loadData(ulli3/liliOrange/liliT-Mobile/
liliVirgin/li/ul, mimeType, encoding);

I've started with a very long page of HTML and whittled it down to
that line. It breaks my webview. If I edit the line at all, it loads
fine every time. I've played with all the webview settings too.

Please put me out of my misery, what's happening here?

I followed your advice, and used DDMS to stop the process of an app in
question.
Interestingly, it did not crash, but the Service was restarted
properly, without any error messages shown to the user.
The value START_STICKY is being (and has always been) returned from
method onStartCommand().
So the problem is caused by something else - I guess.

Well, maybe you should return START_NOT_STICKY, or
START_REDELIVER_INTENT, or add an if statement checking for null - it
just depends on the service.

Read the docs, run your own experiments with DDMS, then decide what is
the right thing to do for your code.

The DDMS Perspective in Eclipse is under Window / Open Perspective /
Other... / DDMS. The Devices tab lets you terminate your own apps's
processes.

Thank, Kostya.

So, you mean that I should return START_STICKY_COMPATIBILITY to avoid
this problem?

But the actual problem then probably lies somewhere else, which may
cause the process to fail/stop in the first place.
It could be some Exception. Why are they not registered?

I believe the above statement is not quite correct about when the intent
may be null, please see this as well:

You can try reproducing the issue on your development device by using
the DDMS tab in Eclipse in killing the service's process. When Android
restarts the service a bit later, check the intent.

Here is the stack trace, which seems to be identical for all crashes
on ALL of the apps in question:

As the Google error report system does not include device type or
Android os version, I do not know if this occurs only one some
specific devices or os version.

Has anyone got an idea as to what is happening?

Thank you.

[android-developers] Transparent Background View with Translucent Activity

2011-12-15 Thread Guian

Hi all !

I've got a weird problem in my interface and I'd like to ask for
comments, if anyone already seen such a case :


I've created a dialog style Activity :
an Activity with translucent background and a listView centered in it.
(so we can see the previous activity around my listview )

the list view has a gradient background and some items in this list
view had transparent background.

What I expect is to see the gradient background of the list view
through the transparent items.

but I don't know why, while scrolling in my list view, I can see the
previous activity in the background of those items.
meaning : the transparent background of my view make me see through
the background of its parent.

when I stop scrolling, the correct background parent is visible
again. :/

I display this layout on a 3.0 device (Samsung Galaxy Tab 7' )

does any one has already seen that ?
do you have a explanation for me ?

[android-developers] Re: openOptionsMenu not working on Honeycomb device

2011-12-15 Thread Royston

Mark,
Generally I would agree with you and if I were starting again would 
probably avoid menu/preferences. Unfortunately this would not be a good 
choice at this stage in my project. The issues I have with the ActionBar 
are to do with inconsistency and uncertainty. Depending  on the size of the 
device I may or may not get a menu icon on the ActionBar. It is asserted 
that if there is not a menu icon on the Action bar there will be one 
somewhere else but this troubles me. On some devices I would wish to get 
rid of a Status bar but you cannot go Fullscreen and still have an 
ActionBar it would seem. 

Again thanks for you feedback, very much appreciated.

Regards

Roy

[android-developers] Re: Edittext in Listview crashes on Android 2.2.3 on back during editing

2011-12-15 Thread havexz

Thanks a lot poncho.

Well that leads to few other questions:

Say I have 1000 items and i want to give in-place editing (say not
using ListView) so now I have to create 1000 editboxes in a
LinearLayout.

Can't it make more sense to use ListView so that EditBoxes can be re-
cycled? Creating 100 EditBox does not make sense.

Also I understand there are focus issues and what not when using
EditBox with ListView, but I can't understand why it is crashing with
Handle visible in EditBox (in ListView)?

Now other option is to give user a way to edit one item in a small
dialog. But his solution is not very elegant for End User.

  OPEN Questions:

  1. Is someone else also face this issue?

 I did, this is how I found the link I sent. 2. Any reason why normal 
 EditText works but EditText in ListView dont?

 Did you read the thread in the link I sent, the first reply suggest that:
 ListView isn't really meant to handle that type of UI with editableentries 
 3. Why IME cursor handle is giving issue in ListView but not
  elsewhere?

 Same as 2.



  Regarding Also is it good to put EditText in ListView or there are
  better options? I have soln for maintaining the content. I can have
  text watcher or something.

  From the same thread:
  vertical LinearLayout wrapped ina ScrollView, containing horizontal
 LinearLayours of the EditTexts andButtons

 Hope this helps

  Hi
  So here is what I did. I have a ListView and each item in it is a
  EditText. Now, just so you know I am using CursorAdapter with
  ListView, and I am creating EditText in newView and filling it with
  some text in bindView.
  Now how to recreate the issue, I just open the activity, click on any
  of the EditText and just click enough to see the orange color handle
  appears with cursor. Now just press back twice. Just press fast enough
  that orange handle still visible on screen. Now wait a sec and you
  have:
  . has leaked window . that was originally added here.
  I tried the normal EditText without the ListView and that works fine.
  What I think is that IME cursor handle is retaining the EditText and
  leading to leak. I also tried EditText with only 'hint' (empty
  EditText) and got same issue in the ListView.
  Now my questions:
  Is someone else also face this issue?
  Any reason why normal EditText works but EditText in ListView dont?
  Also is it good to put EditText in ListView or there are better
  options?
  Well this might be a common issue and some common soln. but I searched
  it found no good soln.
  Thanks in advance.
