Nope, sorry, lol. Just thought clarifying might help you get someone that
has.

If no one shares their experience, you might try looking at a few of the
big boys - companies that would definitely have privacy policies in place
and would probably make use of this feature.

Netflix comes to mind, and they have a Privacy Policy link in their
description, but it's not really clear if this is auto-inserted by Play or
of their own doing.

If you're wondering if the user *must* review this before downloading, then
no, I don't think it's required. I believe it's there for informational and
convenience purposes only.

 Hi All,

 I have 2 applications with different package names. E.g. App1 and App2.

 App1 needs to write some files to App2's internal memory so that it could

 I have used the following in App1 to do so:

 filePath = getPackageManager().getPackageInfo(app2.package.name,

 I can get the correct path but could not write to it. I checked the 
 logcat, it is showing Permission denied.

 Am I missing something? What's else needs to be done?

What about leaving the app and coming back to it later?
What about the user changing their locale settings?
What about users that want to view the app in the layout (landscape or
portrait) that you arbitrarily don't support?

You may think this is fixing the problem, but you're really just hiding it
for the one case, and it *will* resurface in more obscure scenarios and
actually making things more complicated in the long run, giving you a much
bigger mess, which will be much harder to track down and clean up.

Fixing the orientation is *not *a solution for managing dialogs across
rotations - it's a crutch that shitty Android programmers resort to when
they don't want to deal with the complexities of the Android
configuration changes.

Please do not advise people to do this - you're perpetuating bad
information and doing them a disservice.

Re: [android-developers] Android Maps Navigation Tethering..

2012-11-27 Thread Robert Greenwalt

You could use a tethering link for p2p connections, but you'd probably be
better off using a wifi direct link instead - it's made for p2p and has api
for finding the ip address of the other side.

As for your question about the highlighted bit:
Turn wifi tethering on on phone (settings - wirelessnetworks,more -
Tethering portable hotspot - Setup Wifi hotspot - enter a network ssid,
save, Portable Wifi hotspot.

Next on the tablet connect to the wifi network you named above.

Hi Sandhna,

It depends what type of UI are you creating, however, Android provides
different resolution folder called, MDP,HDPI,LDPI based on that, you need
to create different stylesheets or sometimes different layouts.

[android-developers] Homescreen widget - sizing font to fit content.

2012-11-27 Thread MarkG123

Hi, trying to work out how to set a TextView in a homescreen widget, so the 
font is correct and nothing is truncated.

This is a resizable homescreen/lockscreen widget.

Can someone give me a pointer?  Thanks.

[android-developers] How do you show 'Are you sure you want to quit' dialog?

2012-11-27 Thread Subodh Nijsure

Hi,

I want to present a yes/no dialog when user enters back, on main activity
'are you sure you want to quit? ' And if they click ok, quit the
application.

To do this I show a dialog in onDestroy() that asks yes/no question but
that doesn't work. What is correct way to implement 'are you sure you want
to quit the application' dialog?

Re: [android-developers] How do you show 'Are you sure you want to quit' dialog?

2012-11-27 Thread Kristopher Micinski

The application never quits, and so onDestroy() won't be called when the
user pushes the back button (it will be called when Android kicks your
process out of memory).  Instead you would want to override onPause coming
from a press of the back button.

A better solution would be to realize that the application simply doesn't
quit, so asking the user if they're sure they want to quit is silly: since
this won't happen even if they push the back button...

2012-11-27 Thread RichardC

This sounds like an Android anti-pattern.  I would suggest you design your 
app so that is does not need a do you want to quit.

1) onDestroy is not guaranteed to be called.
2) end-users do not expect apps to ask them I they should quit.

[android-developers] Data safety when writing important data to SD card

2012-11-27 Thread Toby


I am opening a file for append using BufferedWriter.  Each time the app
is run, more data is added to the file.  At first a made a little class
representing the file and gave it a write() method that would take a string
and send it out, then flush() the Writer.  I was wondering when I should
close the file, or whether I really needed to.  Will java close the file
for me when the app goes away?  Right now, since the writes are few and
far between, I'm just opening and closing the file each time I write
a line to it, but that seems really awkward.

Thanks,

Toby

What does seems awkward mean, let alone really awkward?

What harm does awkward cause?

What's awkward is holding a resource like a file open for a really long 
time 
when you aren't using it.

File handles are a finite resource. Like all such, you should manage them 
wisely.

Assess the objective costs and benefits of the approach in the context 
where you use it.

Writes are few and far between, depending on what you mean by few and 
far, could 
very well be a use case for closing the file between writes. Or not.

At what point does not few and not far become significant enough to 
justify 
not closing the file?

Almost certainly the non-measurable degree of awkwardness is not relevant.

Id like to match what the final source is to my own app. Maybe i forgot

I have the lifecycle activity source from the sdk, but that isnt it.
That comes on later pages.


Is there a place to download the source? I couldnt find a link.

Alan Cooper's _About Face: The Essentials of User Interface Design_ 
compares a program

points out that you'd 
terminate a human (with extreme prejudice) who behaved like a computer 
program.

Paraphrasing:
You: Give me that document from yesterday.
Comp: What's the name of that document?
You: Name? I don't know - the one you and I were working on!
Comp: I need the name.
You: Name ... name ... ah, here it is - 'MyMemo.doc'.
Comp: OK, I'll get it for you. Where'd we store it?

etc.

If I tell you I want to quit (assuming such a thing is possible), I don't 
expect you to 
nag, Are you really, really sure you really, really want to quit, really?

Re: [android-developers] Data safety when writing important data to SD card

2012-11-27 Thread Joman Chu

Check out the AtomicFile class. It was introduced in API 17. Seems like
prior to the write, it copies the file to a backup file name, and then if
the write fails, it copies the backup back over the original file.

There are other implementations of safe file writing in AOSP. See
frameworks/base/com/android/internal/os/AtomicFile.java and
frameworks/base/core/java/com/android/internal/util/JournaledFile.java. You
won't be able to import these directly, but you can probably just copy the
code because it's Apache licensed.

IIRC, JournaledFile will write to a backup file until the write completes,
then moves the backup over the original file.

Maybe a good solution would be creating a lib project to take care of that

Then, in this lib project you culd use a database, shared preferences or

  What's awkward is holding a resource like a file open for a really 
  long time 
  when you aren't using it. 

 Nice.  I feel better already. 

  File handles are a finite resource. Like all such, you should manage 
  them wisely. 
  
  Assess the objective costs and benefits of the approach in the context 
  where you use it. 
  
  Writes are few and far between, depending on what you mean by few 
  and far, could 
  very well be a use case for closing the file between writes. Or not. 

 A record would be written to the file sometimes every few minutes, 
 and at most every 10 seconds or so. 

  At what point does not few and not far become significant enough to 
  justify 
  not closing the file? 
  
  Almost certainly the non-measurable degree of awkwardness is not 
 relevant. 


 Thanks for clearing the waters.  I feel a lot better about the way I 
 wrote this bit of the code. 

 Cheers. 

 Tobiah 

 P.S., why did you put the [sic] in my quote?  Was it because 
 it would not be java that closes the file, but rather the OS, 
 or rather I'm not even close?

[android-developers] Re: how can i manage security for mysql database permission as global

This has nothing to do with Android. You may have more luck asking in the 
MySQL forums.

[android-developers] Fragments slow to load when coming back

2012-11-27 Thread MathieuB

Hello! 

Here's the situation :

I have a parent activity that have 3 fragments associated with it. 
Basically, there is the actionBar and three tabs. Each tab holds a fragment 
in which there is a listview.

The data are the same for all the 3 listviews, just filtered in different 
way so, in the parent activity, I call a webservice to fetch the data and 
then I push the data to all three fragments and populate their listviews.

When I select an item from one of the listviews, I land on another 
activity. The PROBLEM is, when I come back (to the activity with 3 
fragments), there seems to be a lag from the moment I push the actionbar up 
button and the activity loads. Tough to explain, but when I hit the up 
button, it stays selected for about 2 seconds and then switch to the 
activity.

I'm using setRetainInstance on fragments...other than that, I don't know 
what could be the cause.

Do you have any idea? Anything common about using fragments and coming back 
to this activity after leaving it.

Thank you!

[android-developers] Re: How do you show 'Are you sure you want to quit' dialog?

2012-11-27 Thread shiva pendem

Hi,
here is the code to get the confirmation screen,

  public void onBackPressed() {
 Builder builder = new AlertDialog.Builder(context);
builder.setTitle(application);
builder.setIcon(R.drawable.icon1);
builder.setMessage(Would you like to exit);
builder.setNegativeButton(Exit,
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, 
int id) {
dialog.cancel();
System.exit(RESULT_OK);
}
});

builder.setPositiveButton(Not now,
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, 
int id) {
dialog.cancel();

}
});
builder.show();
   // 
}


paste this code in the intent where you want to have a exit confirmation,

All the best,

Thank 
Shiva Shankar

 Hi,

 I want to present a yes/no dialog when user enters back, on main activity 
 'are you sure you want to quit? ' And if they click ok, quit the 
 application.

 To do this I show a dialog in onDestroy() that asks yes/no question but 
 that doesn't work. What is correct way to implement 'are you sure you want 
 to quit the application' dialog?

William already gave you the answer - you use showDialog, even if it's
deprecated, or use the the DialogFragments.

Your third more ridiculous option is to manage the dialog yourself,
dismissing it onDestroy and recreating it in onCreate if it was previously
showing.
