[android-developers] Re: Jelly bean http post basic authantication give " No authentication challenges found" exception.

[John Gaby]

I don't know if this will help, but I had a similar problem a while back. 
 Only in my case, it worked in the newer versions of Android, but not in 
the older versions.  After consulting with the people running the server 
that I was trying to connect to, I found the problem.  In the header, I was 
sending:

"Authorization": "Bearer XX",


but they were receiving:

"authorization": "Bearer XX",


For some reason, the earlier versions of Android were converting 
'Authorization' to 'authorization' and the particular host that I was 
talking to did not accept the lowercase version.  The fix was to get the 
server to accept both.

I don't know if this has anything to do with your problem, buy you might 
want to consider if the case of your request is correct.

[android-developers] Re: Installation error: INSTALL_FAILED_INSUFFICIENT_STORAGE

[John Gaby]

If you are using the emulator, you can change the size of the internal
storage by adding the following command line argument when you launch
the emulator:

-partition-size 200

Re: [android-developers] Re: [Android LVL] Sporadic false negatives on client devices

[John Gaby]

I also have a small number of users who fail the LVL test (< 1%).  My 
solution is to have my app call my website first to ask if it should do the 
LVL test.  That way, if a user contacts me that it is not working I can set 
it up so that his device no longer performs the check.  I actually 
implemented this from the very beginning, because the whole LVL test 
worried me and I wanted to have a way to override the check if, for some 
reason, it failed to work.  As it turned out, I am glad I did.

[android-developers] Re: Android Market Licensing Problem

[John Gaby]

I have been able to reproduce this problem on my development phone.
If I reset my phone so that there are no accounts at all, then I
receive a 'deny' response.  If I log into my phone with my developer
id, then I can control the response via the Google Developer Console.
However, if I reset my phone and then log in with any random, non-
developer account, then I seem to always get an 'allow' response.
Someone please tell me that this is NOT going to happen once I publish
my app.

Thanks.

[android-developers] Re: Android Market Licensing Problem

[John Gaby]

Well, as I said, with my uploaded, but unpublished app, if I use a
phone that has ANY valid gmail connected to it, it always returns that
it is Licensed (I have tried this on about 10 or so different phones,
with version 1.6 through 2.2).  I am hoping that once I publish it
that this will change, but I have no way of knowing for sure.  This
whole LVL thing may have been an exercise in futility.

[android-developers] Cannot get ANDROID_ID on 1.6 systems

[John Gaby]

I am using the following to obtain the ANDROID_ID for the device:

Settings.Secure.getString(getContentResolver(),
Settings.Secure.ANDROID_ID);

Unfortunately this is returning null on 1.6 system (emulator and
actual devices).

I have also tried using

Settings.Secure.ANDROID_ID;

which is deprecated, but that does not work either.

Does anyone know how to get a unique device id for version 1.6?

Thanks.

[android-developers] Re: Cannot get ANDROID_ID on 1.6 systems

[John Gaby]

I just double checked it on a Motorola Devour running 1.6 and it is
definitely returning a null.  I will see if I can find another 1.6
device and check to see if it is just this particular one.  Given that
this call CAN return null, is there some other way to get a unique id
for the device?

Thanks.

Thanks for the info, but, as I stated at the beginning of this thread,
that is exactly what I am using now, and I can tell you it does NOT
work on some devices.

[android-developers] Re: Cannot get ANDROID_ID on 1.6 systems

[John Gaby]

Ok, I tried it out on an HTC Tatoo also running 1.6, and it returns a
value, so it does happen on only some devices.  However, I really need
a unique id that will work on every device.  Do you have any
suggestions about what I could use in the case where the ANDROID_ID is
null?

Thanks.

Yes he did, and I appreciated his help.  I had posted this message

[android-developers] Can I get a web link to my newly published app

[John Gaby]

I have just published my application and would to be able to provide a
link on my website that will show my application?

Also, if they browse to my website on their phone, is there some kind
of link I can add that the user can click on that will take them to
the market to download my app?

Thanks.

[android-developers] Re: Can I get a web link to my newly published app

[John Gaby]

Well, for the iPhone, you can have a link that takes you to a web page
which shows the same information you see when you look up your app in
iTunes or on the phone itself (i.e. the description, screen shots,
price, ratings, etc).  I take it, by your response, that there is no
such equivalent for Android.  Pity.

[android-developers] Re: Android Market Licensing Problem

[John Gaby]

In case anyone is interested, I have published my app and it now
reports NOT_LICENSED properly.  Still, it seems like all someone has
to do to steal the app is to get the .apk file, change the Package
name, and upload it to Google and not publish.  At that point, anyone
with a valid Google account will be able to use the modified version,
no reverse engineering required.  This does not seem like a very
secure system to me.

[android-developers] Re: Memory Leak with a ListView revisited

In my particular case, I discovered that the leak ONLY happens when I
am debugging the application.  So my conclusion was that my issue, at
least, had to do with some sort of issue with the debugger.

[android-developers] Handling multi-byte Unicode strings in native code

[John Gaby]

How do I detect a lead byte within Unicode string from native code.  I
have used 'isleadbyte' in the past, but that function does not seem to
be present in the NDK.

Thanks.

[android-developers] Horizontal & Vertical Scroll View

[John Gaby]

I need to be able to have a view which scrolls both horizontally and
vertically (e.g. like a browser view).  I have seen several posts
where people have put a horizontal scroll view inside a vertical
scroll view.  I have tried to do that, but I only get vertical
scrolling.  The following is the code I am using:

public class ScrollTest extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);

ScrollView sv = new ScrollView(this);
HorizontalScrollView hsv = new HorizontalScrollView(this);
ImageView iv = new ImageView(this);

int id = getResources().getIdentifier(getPackageName() +
":drawable/level1", null, null);

if (id != 0)
{
iv.setImageResource(id);
}

hsv.addView(iv, new ViewGroup.LayoutParams(1000, 1000));
sv.addView(hsv, new ViewGroup.LayoutParams(1000, 1000));

setContentView(sv);
}
}

Note that if I create just a HorzontalScrollView or just a ScrollView,
they both work independently.  When I combine them, I only get a
vertical scroll.  Does anyone have an Idea about what is wrong here?

Thanks

[android-developers] Re: Horizontal & Vertical Scroll View

[John Gaby]

That is disappointing. From the other posts, it sure seemed like
people had gotten it to work.

I had actually found some code which modified the ScrollView code to
do bidirectional scrolls, but it did not compile, and I was hoping
that it would not be necessary to try and figure out why.  This seems
like something that a lot of people might need.  Why is it not
supported directly?  What does the browser use (it allows you to
scroll in both directions)?

Thanks.

[android-developers] Deleting cached SD card files on uninstall

[John Gaby]

I am downloading and caching some files to the SD card.  I am placing
the files at:

/Android/data/com.gabysoft.myapp

When the app is uninstalled, on some phones (e.g. the emulator and
Motorola Droid), these files are automatically delete (which is what I
want).  On other phones (e.g. HTC Hero and HTC Legend), they are not.

Where can I put these files so that they will be deleted on uninstall
for all devices?

Thanks.

[android-developers] Re: How to make apps installable to SD card keeping them compatible to version 2.1 and lower ?

[John Gaby]

You have to use the 2.2 SDK when you build, but you can still set the
minSdkVersion to an earlier version.  You just need to make sure that
you don't make any calls which are specific to 2.2 when running on an
earlier version.

[android-developers] Bonjour client for android?

[John Gaby]

I would like to be able to create an app which can discover and
communicate with servers running on a PC using Windows or OSX.  This
is very easy to do using Apple's Bonjour, but there does not seem to
be any implementation of this for Android.  Does anyone know of a way
to do this for Android apps, either with some sort of implementation
of Bonjour, or some other mechanism?

Thanks.

[android-developers] Memory Leak in 1.6

[John Gaby]

I seem to have a memory leak when running under version 1.6 of the
OS.  I have a custom view group which contains some controls and I set
it to be the current view via a call to setContentView(vg).  If I then
create a second view group and set it as the active view via
setContentView(newVg), the first view group is never freed (even when
I force a garbage collection).

Note that this works fine for versions 2.0 and above, so it is
possible that 1.6 has some kind of bug.  If so, does anyone know of a
workaround?  I can post a simple example of this problem if it would
help.

Thanks.

[android-developers] Reusing BitmapDrawable objects

[John Gaby]

I have custom skinned buttons.  I set the bitmaps for the button
backgrounds using the addState method of the StateListDrawable class
and pass in a BitmapDrawable which is loaded from a file on the SD
card.  Now I am having out of memory issues, so I thought that I would
try and cache the BitmapDrawable and reuse them for all the buttons on
a page, rather than creating a new one for each button.  However, when
I do this, the buttons don't display correctly.  For example if I have
two buttons of different sizes, the background is drawn at the same
size for both, rather than have each scale.  Also, if one button on
the page is hidden, then the backgrounds for some of the other (still
visible) buttons disappear.  This does not happen if I create separate
BitmapDrawable objects for each of the buttons.

My question is, am I supposed to be able to reuse these objects in
this manner?  If not, how can I keep from duplicating the memory
required to skin each button on a page?

[android-developers] Re: Memory Leak in 1.6

[John Gaby]

Thanks for the response.  I have worked out a work-around which fixes
the problem.  Instead of setting the view group via
setContentView(vg), I am now setting a FrameLayout as the content
view, and then setting the view group as the child of the
FrameLayout.  In addition, it was necessary to not remove the old view
when setting a new view, but rather hide it.  Then when subsequent
views are set, the oldest view is removed.  It seems that the problem
stems from removing a view while processing a message from a child
control in that view.  If I don't do that, then the view is properly
recycled.  Again note that this seems to be a problem only for 1.6
(and possibly earlier).  It seems to work properly with 2.0 and above.

[android-developers] Re: app2sd - not working

[John Gaby]

I believe that installing on the SD card is supported only for 2.2
devices (or higher).  Your program will install on earlier versions,
but it will not install to the SD card.

[android-developers] Re: LVL: possible to check license for a different app?

[John Gaby]

Interesting idea, but I do not believe that the Market will let you
publish a free app which asks for CHECK_LICENSE permissions, so I
don't think that your free app will not be allowed to use LVL.

[android-developers] App Add-on

[John Gaby]

I have a game for which I would like to be able to sell add-on packs.
I would prefer that there was some in-game way to make these
purchases, but, alas, there does not appear to be any such mechanism.
I am considering the idea of creating separate add-on apps which, when
run, would add features to the game.  I believe that I have seen this
done by others.  My question is, how do people deal with the refund
process.  I mean, the user will be able to purchase the add-on, run
it, and then request a refund, which would result in them getting it
for free.  Has anyone else had experience with this model?

Thanks

[android-developers] Re: App Add-on

[John Gaby]

Yes, I would check for the existence of the add-on, however, it is
likely that the user would like to get rid of it at some point so it
does not clutter his desktop.  It would be nice to allow for that.  I
have thought that I could check for its existence only for 24 hours,
and then not check any more, but I would need to explain to the user
that he need to leave the add-on installed for at least 24 hours.
This seems quite messy to me.  I was hoping that someone who has tried
this could give me some feedback on their experience.

Thanks

[android-developers] Re: App Add-on

[John Gaby]

Thanks for the reply. So, it is possible to setup the intent so the
app does not appear on the desktop?  If so, how does the user run it
for the first time (to install the add-on)?   I am fairly new to
Android development and not that experienced with setting up intents,
so any help in that direction would be most appreciated.

Thanks.

[android-developers] Re: App Add-on

[John Gaby]

Thanks for the links, they were most helpful.  I worry, however, that
if I remove it from the Launcher that the user may not understand why
it is not there, and may not be able to figure out how to launch it.
I don't suppose that there is any way to remove it from the launcher
after it has been run?

Has anyone used this model before?  If so can you tell me what kind of
problems with users you encountered?

Thanks.

I know.  I really wish that Google had an in-app purchase mechanism
like Apple (or would allow the use of 3rd party in-app purchasing like
PayPal).  Maybe I need to rethink this whole concept.

Thanks much for your help!

[android-developers] Protecting files on non-rooted phones

[John Gaby]

I find that, when using a actual device that is not rooted, that I
cannot see the contents folders created by my application.  However,
if I know the exact name and path of a file, I CAN pull or push it
using ADB.  Is there a way to prevent external access to application
files (on a non-rooted phone, of course).

Thanks

I must be setting the files as world readable then.

I didn't know that if the app was debuggable that you could change the
shell to run as an app uid.  Can you tell me what version of Android
that works for, and how I do that?

Thanks.

[android-developers] Re: App Add-on

[John Gaby]

Thanks for the input.  Your solution would be nice IF Google would
implement it.  They could also implement an in-app purchase mechanism
like Apple's, which works quite well.  However, I wouldn't hold your
breath waiting for either of those to happen.

As for having a content provider keep track, there is no way to match
purchases from the Market to user's devices.  That means that the user
would have to run the add-on app so that it could communicate with the
server.  This has the same problem that I am facing now, but also adds
the requirement that the user have internet connectivity to run his
app.

[android-developers] Re: First attempt at LVL Licensing

[John Gaby]

It has been my experience that LVL CANNOT be fully tested before
publishing.  Like you, I found that an unpublished app returns
inconsistent results.  If I set the response to denied, for example,
on some phones I got the correct result, and on others I did not.
After I published the app, it did seem to work correctly, but of
course I could only see the results on the phones I had access to.
You just have to take your best shot and hope for the best.

[android-developers] App Widget

[John Gaby]

I am trying to create an App Widget for the Home screen which displays
a line of text. When the user clicks on the Widget, I want the text to
change.  I have pieced together the following which seems to work,
however I am concerned about how I am providing access to the
AppWidgetManager in the onReceive call.  I need the AppWidgetManager
there because I wish to change the text.  I tried adding a class
member variable, 'm_appWidgetManager', which I set during the onUpdate
call.  However when I get the onReceive call, this value is null.  Is
this because the onReceive is called with a different instance of my
class, and if so, why is that?  If I chang m_appWidgetManager to be
static, and it all seems to work, but this does not seem like the
correct solution.

Can anyone tell me how to do the properly?

Thanks.

Given that it creates a new instance of my AppWidgeProvider class for
each call, is there a way to have persistent data associated with my
widget?  That is how can I store data that will still be present on
the next call (other than writing it to disk)?

[android-developers] Debugging App Widgets

[John Gaby]

I am trying to debug an App Widget and I find that if I set a
breakpoint in the onReceive message, that I can only leave it stopped
in the debugger for 30 seconds or so, before my process is killed.  If
I look in logcat, I see line about a 'Timeout of broadcast
BroadcastRecord...' and then my process is killed.  Is this because
the Home page is waiting for a response and gives up after 30
seconds?  Is there a way to increase or eliminate this timeout so I
can trace through my code?

Thanks

[android-developers] Screen rotation with App Widgets loses onClick connection

[John Gaby]

I have an App Widget on the Home screen which works fine until the
screen is auto-rotated.  At that point, the onClick connection (set up
via a call to setOnClickPendingIntent) is lost.  The only way I seem
to be able to get it back is to delete the Widget from the Home screen
and then add it back.  Is there some kind of message that tells me
that the screen has rotated that I need to respond to (and reestablish
the connection)?

Thanks

I figured that it was recreating the Widget on rotation.  The problem
is, I don't seem to be getting any messages to that effect, and have
no way (that I can see) of re-establishing the connection.  How can I
determine that a rotate has happened and set up a new onClick
connection?

[android-developers] Re: Android phone for development

[John Gaby]

I am using a Motorola Droid and an HTC Hero (both purchased used
through ebay), and find them to both work well.  The phone does not
need to be rooted or unlocked, and no phone service is required,
unless your app make use of phone services.  Also if you want to be
able to test on a lot of different devices, there is a service which
allows you to connect to phones remotely.  It has it's problems, but
have found it somewhat useful (although it is a bit pricey).

[android-developers] App Widget disappears on reboot

[John Gaby]

I have an App Widget which I place on my home screen.  It seems to
work fine, but when I reboot the phone, it is not only gone from the
home page, but is missing from the App Widget list, so I cannot add it
again.  Does anyone have any idea what might be going on here?

Thanks.

[android-developers] Re: App Widget disappears on reboot

[John Gaby]

Actually, after playing with it a bit, I have determined that the
problem lies with installing the app on the SD card.  Apparently the
card is not mounted in time during a reboot.  I presume that it is
simply a bad idea to have a Widget that runs from the SC card, because
the user can unmount it at any time.

My Widget is part of a larger app, which I would still like to install
on the SD card.  I don't suppose that there is any way to install a
second APK file for the Widget on the phone, is there?

Thanks.

Yes, that is what I was thinking as well (I was asking if there was an
automatic way to install a second APK, I did realize that the user
could manually install one).  If I put up a message when the app is
first installed telling them that they can install the Widget app, and
providing a link to the Market, do you think that I will get a lot of
flack.  Note that use of the Widget is an optional feature, and there
may be many who simply will not use it at all.  Considering that many
phones don't have a lot of internal storage, I really don't want to
force the user to install the whole app on the phone just to get a
Widget that he may not really want anyway.

[android-developers] Sharing files between apps

[John Gaby]

I have two applications which can access each others files.  To get a
path to a file in the other app, I am using the context.getDir(...)
function to get a path to the file for the running app, and then
changing the package name component of that path to the package name
of the other app.  This seems to work, but I am wondering if this is a
reliable way of doing this, or if there is another more appropriate
way.

Thanks.

This seems to be what I am looking for, however, when I call it with
the package name of the other app, it returns null (I get nothing from
logCat either).  I can use the PackageManager and retrieve the info
for that same package, so I am pretty sure I have the name correct and
the app is installed.  Do you have any ideas about what might be
wrong?

I am using a sharedUserId, however, the two apps are unified.  In
fact, I would much rather have just a SINGLE app.  However, I want the
user to be able to install the app to the SD card, but it includes a
AppWidget component (which is optionally used) which cannot reside on
the SC card.  This seems to be forcing me to create two apps, may main
app, and a separate app to handle the AppWidget.  If there is a better

The following is the routine that I wrote to test the function.  The
call to manager.getPackageInfo works, but the call to
GetPackageContents returns null.

private void Test()
{
String pkg = "com.gabysoft.quizardwidget";

PackageManager manager= getPackageManager();
PackageInfoinfo;

try
{
info = manager.getPackageInfo(pkg, 0);

int v = info.versionCode;
}
catch (NameNotFoundException e)
{
}

Context c = GetPackageContext(pkg, CONTEXT_INCLUDE_CODE);
File file = c.getDir("data", Context.MODE_PRIVATE);
String path = file.getAbsolutePath();
}

I actually tend to agree, but I really hate to force the user to
install the app to internal memory (there is a fair amount of
content).  The feedback I have gotten so far from the users that I
have asked is that they would rather see a separate app than loose the
ability to install on the SD card.  Is there ANY other way to deal
with this?

Thanks.

Well, now don't I feel sheepish!  It was indeed a typo, and the ever
so helpful editor created a GetPackageContext for me and returned
null.  Sorry about wasting your time.

As for your other suggestion about using a broadcast to get the data,
that does seem like a good idea.  In fact, the widget itself uses a
broadcast intent when the user click on it to get the next set of data
to display.  I assume that I could send that broadcast to my main app
just as easily as it does to the Widget app.

Thanks for the help and suggestions.

[android-developers] TextView with a top margin that is proportional to the height of the parent view

[John Gaby]

Is there a way to position text within a linear layout such that the
position of the text is proportional to the height, rather than a
fixed distance.  For example, I would like the text to be displayed
down from the top a distance equal to 20% of the height of the view.

Thanks.

[android-developers] Cannot install App on HTC Hero

[John Gaby]

I have an application (which contains an NDK component) which will not
install on my HTC Hero (OS ver = 2.1u1) It does install on the
emulator, and on a Motorola Droid (OS ver = 2.2).  The following is
the logcat which seems to indicate some problem with installing my .so
file.

Does anyone have an idea at to what might be wrong here?

Thanks

[android-developers] Re: Cannot install App on HTC Hero

[John Gaby]

Yes, they are compatible, in fact, I have previously installed this
app on the Hero before and it has worked fine.  The version I was
tying to install was signed, so I decided to rebuild the app and
install the Eclipse signed version (which previously worked).  However
now it tells me that it the signatures don't match even though I had
deleted the old signed one from the phone before I tried to install
the new one.

[android-developers] HttpsURLConnection's getResponseCode() returns -1

[John Gaby]

I am trying to use HttpsURLConnection to connect to a secure site, and
it is failing and getResponseCode() is returning -1.  The following is
the code that I am using.  Note that this very same code works in
other cases.  Can anyone give me a clue as to why I might get the -1,
and how I can get more information about what is going wrong.  Also
note, that if I take the URL that I am trying to connect to in this
call and paste it into a browser, I get the correct response, so I am
pretty sure that the URL itself is correct.  In this particular call,
m_data is null, so it is performing a GET and no data is written.

Thanks

HttpsURLConnection connection = null;

try

URL url = new URL(arg0[0]);
connection = (HttpsURLConnection) url.openConnection();

// Allow Inputs & Outputs if there is data to send
connection.setDoInput(true);
connection.setDoOutput(m_data != null);
connection.setUseCaches(false);

// Enable GET or POST depending on whether there is data to
send
connection.setRequestMethod((m_data == null) ? "GET" :
"POST");

connection.setRequestProperty("Connection", "Keep-Alive");
connection.setRequestProperty("Content-Type", "application/
octet-stream");

if (m_data != null)
{
DataOutputStream outputStream = null;

connection.setFixedLengthStreamingMode(m_data.length);

outputStream = new
DataOutputStream( connection.getOutputStream() );
outputStream.write(m_data);

outputStream.flush();
outputStream.close();
}

// Responses from the server (code and message)
int serverResponseCode = connection.getResponseCode();
String serverResponseMessage =
connection.getResponseMessage();

InputStream inputStream = connection.getInputStream();

int nBytes;

m_curBytes= 0;
m_totBytes= connection.getContentLength();

[android-developers] Re: HttpsURLConnection's getResponseCode() returns -1

[John Gaby]

Thanks for the tip, that does indeed fix the problem.  Can you tell me
what the ramifications of setting the keepAlive to false are?

Thanks.

[android-developers] Controlling allowed orientations at runtime

[John Gaby]

I have an application which I want to behave differently depending on
whether it is installed on and phone or tablet sized device.  On the
phone devices, I want to support both portrait and landscape mode.
When it is installed on a tablet device, I wish to only support
landscape.  Now, using the manifest, I can add a line:

   android:screenOrientation="landscape"

to the activity, and it will force the app to remain in landscape
mode.  However, I want to be able to set this at runtime only when I
detect that the device is a Tablet.  Is there a way to do this?

Thanks.

[android-developers] Re: Comments/Ratings not showing up on Market

[John Gaby]

I have had this happen at least 3 times.  A user told me that they has
submitted a review, but I could not see it.  I asked them about it and
they send me a screen shot clearly showing the review, however, when I
looked at the same page it simply was not there.  There is something
definitely fubar with their rating system.

[android-developers] Using view.invalidate

[John Gaby]

I have a custom view that changes when the use moves his finger over
it.  Each time I receive a move event, I call invalidate to invalidate
the view, and then it is redrawn on a subsequent onDraw.  I have a
relatively slow device, where it takes about 0.2 seconds to paint the
view.  I am finding, on this device, that as I move my finger around,
all of the move events are queued up and I seem to get an onDraw event
for each one, so after I pick up my finger, the display continues to
change as all the move events are processed.

What I want is to NOT queue up move events while processing the onDraw
method.  How can I accomplish this (or am I not doing something right,
in the first place?)

Thanks

[android-developers] Strange problem with SurfaceView on a tablet device

[John Gaby]

I am trying to create a class that extends SurfaceView which I am
using to animate some images.  On a particular tablet device
(800x600), if I create an instance of my view and set it as the main
view (i.e by calling setContentView), it works fine, even in landscape
mode where the with is 800 pixels.  However if I place it in a Linear
Layout, and make the width greater than about 700 pixels, then the
view paints with an odd skewed transform.  If my view extends View,
instead of SurfaceView, then it paints correctly at any size (but, of
course, I cannot animate it).

Now this does not happen when using the emulator, and on some other
devices, so I am guessing that it is some kind of bug with this
device.  However it worries me a bit (i.e. I wonder what other devices
might exhibit this behavior), and was wondering if anyone else has
seen anything like this when using SurfaceViews, and whether there is
any kind of workaround.

Thanks.

[android-developers] Re: Strange problem with SurfaceView on a tablet device

[John Gaby]

As an update, I have further discovered that if I make the width 800
(i.e. the width of the display in landscape mode), then it will work
properly even if it is a child of a LinearLayout.  It only seems to
fail if the size is somewhere between 700 and 800 pixels.

[android-developers] Re: ListView leaks memory II

[John Gaby]

Kostya asked if you were running under the debugger.  This is relevant
because previously I too had a memory leak involved with ListViews and
eventually discovered that it only happened if I was running under the
debugger.  So if you are running under the debugger, you might check
it without the debugger running to see if you still have a problem.

[android-developers] Notification bar always shown on ViewSonic g tablet

[John Gaby]

I have an app which hides the title and notification bar and runs full
screen.  I use the following line in the manifest to accomplish this:

android:theme="@android:style/Theme.NoTitleBar.Fullscreen"

This seems to work find on phones and some tablets that I have tried.
However, on the ViewSonic g tablet, although my app still runs
'Fullscreen', the notification bar is still present and overlays my
view.  The problem is, that if I have controls that are underneath the
controls on the notification bar, the user cannot access them.

Is there a way I can specifically hid the notification bar?

Thanks.

[android-developers] Re: Notification bar always shown on ViewSonic g tablet

[John Gaby]

Thanks for the response, you are correct in that it does not have the
Android Market.  However, there are apps that run full screen without
that bar, so there must be some way to turn it off.

[android-developers] Received authentication challenge is null

[John Gaby]

I am trying to connect to a site using the oAuth protocol, and I am
getting the exception 'Received authentication challenge is null' on
some devices when I attempt to make a https post.  Now this was
previously working in the emulator, but I now see the error there as
well.  I did a web search, and it seems like I would get this
exception when I receive an 401 error from the site.  Others said this
was due to a malformed authentication header, but I am not setting a
authentication header at all for this call.

This exact same code works on a number of devices, and used to work in
the emulator (I cannot figure out what has changed).  The person who
runs the site has checked his logs, and does not see an error on his
side at all. Does anyone have any idea what might be going on here?

Thanks.

[android-developers] Re: Received authentication challenge is null

[John Gaby]

I have found the problem.  It turns out that if the time stamp on your
oAuth call is incorrect, the server returns a 401 status error which
on Android devices causes the "Received authentication challenge is
null" exception to be thrown.  All of the devices that were having
this problem had incorrect times, and fixing the times fixed the
problem.

[android-developers] Website not working when displayed in a WebView

[John Gaby]

I have a website which has a forum, and if I view the site using the
phone's browser, it works fine.  However, if I view the site from
within a WebView inside my app, some of the buttons do not work.  For
example, if I click the 'New Post' button, nothing happens when in a
WebView, but it works fine inside the browser.

Does anyone have any idea why it behaves differently in a WebView than
a browser?

Thanks

[android-developers] I am trying to receive broadcast datagrams

[John Gaby]

I would like to be able to receive broadcast datagrams.  I am using
the following code:

public void Receive()
{
EnableMulticast();

String text;
byte[] message = new byte[1500];
DatagramPacket p = new DatagramPacket(message,
message.length);
try {
DatagramSocket s = new DatagramSocket(45454);
s.receive(p);
text = new String(message, 0, p.getLength());
Log.d("GabySoft", "message:" + text);
s.close();
} catch (SocketException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}

Now if I send a datagram to the ip address of this device, it receives
the message.  However, if I send a broadcast datagram, I do not get
it.

By doing web searches, I found that it appears that most phones have
the ability to receive broadcast datagrams turned off to conserve
power.  I found the following code which supposedly turns that ability
back on, and I am calling it at the beginning of the 'Receive'
function:

private void EnableMulticast()
{
if (lock == null)
{
try
{
android.net.wifi.WifiManager wifi =
(android.net.wifi.WifiManager)
 
getSystemService(android.content.Context.WIFI_SERVICE);
 lock = wifi.createMulticastLock("HeeereDnssdLock");
 lock.setReferenceCounted(true);
 lock.acquire();
}
catch (Exception e)
{
e.printStackTrace();
}
}
}

However, even after calling this function (which succeeds), I still do
not receive broadcast datagrams.

Can anyone tell me how to make this work?

Thanks.

I have a customer with a Samsung Tablet and he tells me that the app
Icon does not show in his list of applications.  It does show on the
settings page, however, and if he goes to it using the Android Market,
he can launch it from there.  I do not have a Samsung Tablet to try.
Can anyone tell me why this might be happening?

Thanks.

The app is Quizard Flashcards.  There is also a lite version, but I am
not sure if it is happening with that one as well.  I will ask the
user to scroll down through the entire list to see if he can find it.

Thanks.

Thanks for giving it a try.  I have asked my user to look for it at
the end of the list.  Hopefully he will find it there.

[android-developers] User cannot install an update

[John Gaby]

I have a user who is trying to install an update and it is failing.
He has sent me the logcat and it seems to be failing because of some
kind of incompatibility with the shared UserID.  However, I am able to
install the same update over the same old version without this
problem.  Here is the relevant logcat section.  Does anyone have an
idea as to what might be going wrong.

[android-developers] Re: User cannot install an update

[John Gaby]

There is one more relevant point.  I have had the user completely
uninstall the app and re-install the new version and the above log is
what he is seeing

[android-developers] Re: User cannot install an update

[John Gaby]

Thanks for the suggestions.  I had the user try taking out the battery
but it didn't help (I HAD previously had him reboot his phone which
didn't work either).  I am beginning to think that there is something
screwed up with the permissions as you suggest.  I have actually had a
similar problem on my HTC Hero phone running 2.1 (he is running 2.2).
It gets into a state where I can no longer install my app and it
clearly appears to be a permissions problem (I can't remember the
exact message, but it fails to install something complaining that the
folder doesn't exist).  I have had this happen a number of times and
it usually occurs when I have installed a debug signed apk, un-
installed and then tried to install a signed apk.  However my user has
only ever had properly signed apks.

Ultimately the only way I was able to get it to work again on my HERO
was to reset the entire phone to the factory settings (which deletes
everything), which is not something that my user is wanting to do.

[android-developers] Re: User cannot install an update

[John Gaby]

You are, of course, correct.  I just wanted to understand what is
happening here so that I can determine whether it is my fault or not,
and whether I am going to have others that have this problem.  The
reality is that for every person that takes the time to report a
problem there are probably dozens (or hundreds?) who don't bother.

[android-developers] Re: User cannot install an update

[John Gaby]

Thanks for all your help, the user does not have root access and is
not willing to reset his phone.  Rebooting the phone also does not
help (or so he tells me). So I guess that he is simply stuck with his
current version.

Thanks again.

[android-developers] setRequetProperty seems to change the case of the Field string to lowercase on pre 2.3 Android devices

[John Gaby]

I am having a problem with setRequestProperty on pre 2.3 versions of
Android.  I am trying to implement an OAuth2 protocol to connect to a
website (which is not under my control), and it requires the header
field 'Authorization' to have the first letter capitalized.  Since
setRequestProperty is converting it to lower case my app fails on pre
2.3 devices.  Here is a thread that I found from 2010 that refers to
this problem:

http://code.google.com/p/android/issues/detail?id=6684

Does any have a workaround for this problem that will allow me to
create a version of my app which will work on pre 2.3 devices?

Thanks.

[android-developers] This application is available to over 0 devices

[John Gaby]

I have uploaded an APK file for a new app, and it is telling me that
'This application is available to over 0 devices'.  The Manifest for
this app is nearly identical to another of my apps which shows it
being compatible with over 600 devices.  Does anyone have any idea
what might be wrong?  If I publish this app as it is, will it actually
be available on devices?

Thanks.

[android-developers] Re: This application is available to over 0 devices

[John Gaby]

Are you saying that I will not be able to see the correct number of
devices until I activate the APK (I don't remember it working this way
before)?  If I do activate the APK, will that automatically publish,
or will I still be able to do that later?

Thanks.

[android-developers] ListView + EditText

[John Gaby]

I have a ListView which displays rows which can have a variety of
controls.  If the row contains TextViews, ImageViews, and/or Buttons,
everything works as expected.  However, if I add a EditText control to
a row, then I no longer seem to be able to select a row (touching
outside of the EditText control, of course).  Note that if I have a
button on the row, it still works, but if I touch the row itself,
onItemClick never fires.  Is it not possible to have EditText controls
on rows of a ListView?

Thanks.

[android-developers] ImageView scaling produces poor results

[John Gaby]

I have an ImageView control, and if the image in question needs to be
scaled down, it seems to be down, the quality of the resulting image
is very poor.  I have looked for a way to control the scaling (e.g.
set it to bicubic), but am unable to find a way to do it.  Can someone
tell me how to improve the scaling of images?

[android-developers] Replacing an APK file for a not yet published app

[John Gaby]

I have created a new app and uploaded an APK file but have not
published it.  Now I would like to replace the APK file with a
different one.  If I try and upload another with the same version
code, it will not accept it.  If I try and delete the existing APK
file first, the ENTIRE freaking app is deleted and I have to start
over.  Surely, there is a way to replace the APK file for a non-
published app without having to re-enter all of the other meta data.
I used to be able to do this.

Thanks

[android-developers] Re: Replacing an APK file for a not yet published app

[John Gaby]

Really?  Wow.  I know that I can bump the version code, but since I
haven't released it yet, that should not be necessary.  Actually I
like to get all of my meta data entered and only upload the final APK
file as the last step.  Since they would not let me enter the meta
data without uploading an APK file (why is that?) I uploaded my
current version at the time.  Then when I tried to upload the final
version, the entire thing was deleted (I never dreamed that clicking
the 'delete' on the APK page would delete the whole app). Why do they
make this so hard?

Thanks.
