[Michael Roland]

Hi,

That depends on what type of RFID tag you want to read. NFC devices can 
read a subset of RFID tags.

See this screen grab:
Yesterday, at least four different versions got installed by users, even

Good thought, but it also does not work. The problem is the same: 
java.lang.UnsupportedOperationException, when I try to wrap the key. This 
only happens in Android 4.2. Everything works fine in 4.1 and every other 
previous version I've tested.

When I select the android:fragment, I've found out that what happens is an 
entire new
SettingActivity is started.  I was only expecting a new HostsFragment to be 
created.
I'm obviously missing something fundamental about the PresenceFragment life 
cycle.
I'm reading the docs, but I just don't see my misunderstanding.

Thanks for any help you can offer,

Bingo. An android:targetSdkVersion of 11 or higher gives the dismiss
behavior; 10 or lower does not.

No, still no change -- taps outside the dialog-themed activity have no
effect. android:windowCloseOnTouchOutside is having no effect, true or
false, so for the moment I am chalking this up to a flawed scrap app
that I am trying this out with.

Odd.  May be related to my use of a drawable.xml for the dialog window

*styles.xml entry:*

@drawable/rounded
false  


*rounded.xml:*

I'd be curious to know if you still don't see it.  Maybe there is something

Curiously, I can't reproduce that behavior on a 4.1 emulator, or a

Re: [android-developers] How to make Activity with Theme.Dialog modal?

[Blake B.]

Mark, thanks for the quick reply.

Well, this may not be a problem on older APIs after all.  I was testing on 
4.x devices (Moto Xoom and Samsung GSIII) and touch events outside of the 
dialog (the Activity using Theme.Dialog) cause the dialog activity to be 
cancelled and the events do get passed back to the background activity. 
 Adding the "android:windowCloseOnTouchOutside" in the style definition 
prevents this in API 11 and higher devices.

However, it appears that in older devices (I've tested on emulators using 
2.2 and 2.3.3), the touch events do NOT get passed back by default, so 
there may not an issue for me here.  This default behavior may have changed 
in new versions of Android.

One exception I have seen is for the original Kindle Fire, running 2.3.4 (I 
have not tested on the newer Kindle devices).  It handles a touch outside 
the dialog as a "back" button press.  In the logcat I see this message: 
"Simulating 
back button on press outside dialog" followed by the call to 
onKeyDown(keyCode, KeyEvent), which is simple to override and ignore for 
keyCode 
== KeyEvent.KEYCODE_BACK.

So, I believe between these 3 different behaviors, I am able to prevent the 
issue in my original post.  Hopefully this is helpful to others along the 
way!

Regards,
Blake

I just tossed together a quick scrap app, with a regular Activity
launching a Theme.Dialog activity. Nothing special, and on a 2.2
emulator, touch events outside the dialog are not delivered to the
visible regular activity. Leastways, the buttons I try tapping on in
the non-foreground activity do not respond.

So, if you can reproduce your findings in something we can look at,
that would be very interesting.

AFAIK, it should not do that. Do you have a sample app that

Re: [android-developers] Using a logo instead of icon in a SearchView and postioning of a ViewSwitcher

[farble1670]

sorry for the "me too" post, but me too. i'd really like to understand 
what's going on with the launcher vs. logo.

 Hi all,

 Recentely we've published a Android app which is developed according to 
 the Android design guidelines:
 https://play.google.com/store/apps/details?id=nl.jip.benzineapp

 This app uses a logo instead of the launcher icon. In the app a search 
 function is present in the ActionBar. There is also ViewSwitcher present 
 in 
 the ActionBar.

 Now we have two problems with the ActionBar.


1. We aren't able to show the custom logo instead of the laucher 
app icon in the SearchView, see attachment. This should be possible, 
 this 
is accomplished in the YouTube app for example. Any suggestions how to 
accomplish this?

2. When the user navigates between the default ActionBar and the 
SearchView the positioning of the ViewSwitcher becomes incorrect, see 
attachment. Apparently this is a known problem: 

 http://stackoverflow.com/questions/12115372/android-margin-between-actionbar-icon-and-navigation-dropdown-menu-changes-when
When we apply the suggested solution the custom logo is replaced by 
the laucher icon. Any suggestions how to avoid this?


 Thanks,

 Martijn van Mechelen

[android-developers] How to make Activity with Theme.Dialog modal?

[Blake B.]

I have an Activity that is using the Theme.Dialog theme to present a dialog 
to the user.  By default however, when the user touches outside of the 
dialog window, the touch event is passed to the views of the Activity in 
the background.  For API level 11 devices and higher, I can use the 
following attribute in the Theme's style definition:

   false

but of course this does not work on older (2.x) devices.  I have also tried 
these calls in onCreate():

   getWindow().setFlags(LayoutParams.FLAG_NOT_TOUCH_MODAL, 
LayoutParams.FLAG_NOT_TOUCH_MODAL);
   getWindow().setFlags(LayoutParams.FLAG_WATCH_OUTSIDE_TOUCH, 
LayoutParams.FLAG_WATCH_OUTSIDE_TOUCH);

Although these will notify my dialog Activity a onTouchEvent() call with 
a ACTION_OUTSIDE action, the event still gets passed back to the background 
activity and views.  How can I make my Theme.Dialog Activity modal without 
using a Dialog class explicitly?

If you made changes to the app that would prevent it from being available
to older devices (like you changed minSDK to 2.1), users with those devices
stop getting updates, but the old version of the app is still available,
and this is what they see and download.

Re: [android-developers] Mobile network idle sockets disconnected

oops..  I truncated a sentence..

updateDataStallInfo logs show what's going on when a stall is detected.  In
your log you can see that 21 packets have been sent since you last received
a packet.

 Can you get radio logs?  This is the system log - there are several log
 buffers.  A bugreport (adb bugreport > mybug.txt) would get them all.  Then
 you can match the connectivityservice dropout with what happened in the
 radio.

 I don't think you should open a bug: this is not an android issue, but
 rather it's a samsung issue.

 I have opened an internal issue to expand CTS to check for this - any
 device wanting to claim to be an android device would not be allowed to do
 such a thing in the future.

Re: [android-developers] Mobile network idle sockets disconnected

[Robert Greenwalt]

The data stall detector is watching for outgoing packets with no
corresponding return.  If it sees this for X (6 minute default) it tries a
bunch of things and one of those steps is to tear down and rebuild the
connection.  That's what you're seeing.  I believe UDP packets may get
ignored, thus my tcp/udp question.  You can see some log lines in the radio
log like "updateDataStallInfo: OUT send=..." that show what'

What are you doing in your keepalive pings?  Sending a char with no
response, or echoing a response back?  That could cause the problem because
there'd be outgoing traffic but no incoming traffic.  If there were NO
outgoing the data stall detector shouldn't fire.  If you change your
keep-alive to send both ways you should be fine.

This makes me wonder what your other test device is doing - the one that
doesn't show this problem.  Are you using rooted devices?  They would allow
you to use tcpdump and look at the network traffic..

 Thanks again for the feedback. I traced the logs from samsung with a

Re: [android-developers] LocationManager minDistance settings question

[Kristopher Micinski]

FYI minDistance cannot be guaranteed to work the way you want: it may
fire sooner (or perhaps later), it's more of a guide than a hard
parameter.  (In fact, before additional CTS testing, I believe it was
sometimes disregarded entirely, because of a bug in some devices, this
was for certain with minTime...)

I'm not sure what you mean by "most efficient?"  If you app is
listening for updates, it's going to be alive, which means it's going
to take memory.  It's a sort of misconception that requesting updates
less frequently dramatically reduces your energy footprint, this isn't
quite the case (given only my playing around with things, though).

Keep in mind that your app could just die after a while.

Maybe it's some other service that is stalling?
The SIM card uses a specific APN that only allows it to connect to our

 Hi all,

 Seems that Android is dropping idle sockets when under a mobile
 network. Usually, no socket is kept alive for more than 7 minutes of
 inactivity. I am using a SIM card with a particular APN, that allows 
 idle
 sockets for at least 30 minutes - this was tested using another kind of
 device, also communicating with GSM, and there are no drops, so problem
 isn't the SIM card.

 After a few searches in the web, I tried a few approaches to work
 around this, but until now, no success. I tried using a partial wake 
 lock
 after connecting, releasing only when disconnected - didn't work. Also
 tried using only a 2G network, as some said that changing from network 
 type
 could impact on this - same outcome.

 After digging a bit more and by analyzing logcat, I watched that a 
 CONNECTIVITY_CHANGE
 is sent after some idle time, disabling the data transfer availability
 (active network is mobile, no connectivity) and another one is sent
 enabling it again (active network is mobile, connectivity). This cuts 
 off
 all live so

Interesting.

Maybe it is an android bug!

What kind of traffic are you sending?  tcp?  udp?

 I would look in the log for the timestamp of the ConnectivityChanged
 broadcast and then check the radio log and see what's going on.

 I suspect there is an unsolicited data call list notification coming
 from the radio showing that the data call has gone away.  Perhaps just
 before that there may be something explaining why.

 You may have to contact samsung if you're sure that other devices have
 longer connection times on the same carrier.

 Hi Robert,

 Thanks for the reply. If I send a packet every 5/6 minutes the
 connectivity is maintained yes. Only if connection is idle for longer than
 that. The weird thing is that it's not an exact timer, even though the
 average is very close. Sometimes it lasts 7 minutes, sometimes 8 or 9. I
 even saw this happening with a 4 minute interval, though very rarely. On
 the other device, I can most of the times maintain higher idle times.
 I'll try to look at the logs more carefully to see if there's something
 else. Is there anything in particular that I should look for?

 Cheers

Re: [android-developers] Why does my Hello World app require three permissions?

[Kristopher Micinski]

These were added early on..., I believe around 1.5?  You can check,
but I'd just set my minSdk to be as low as possible, probably 2.2.
(So, 8.)

In general, you will take the lowest feature set you need and set your
API level at that.  If you're using ActionBar you might run into
problems, but there are generally compatability libraries for earlier
API levels (e.g., ActionBarSherlock...)

[android-developers] LocationManager minDistance settings question

[g...@deanblakely.com]

I'm converting some of my Windows Phone apps to Android.  The apps all 
revolve around movement tracking.  In WP7 the location watcher has a 
"MovementThreshold" property that sets how much movement is necessary for 
the GPS to trigger a movement event.  Typically we want a lower threshold 
when walking and a higher one when in a jet airplane.  It can be throttled 
with code like this that changes it every time we get movement if the speed 
changes.
 if (mph < 7) watcher.MovementThreshold = 5;
else if (mph < 15) watcher.MovementThreshold = 20;
else if (mph < 30) watcher.MovementThreshold = 100;
else if (mph < 50) watcher.MovementThreshold = 400;
else if (mph < 100) watcher.MovementThreshold = 800;
else if (mph < 120) watcher.MovementThreshold = 1200;
else if (mph < 200) watcher.MovementThreshold = 2400;
else if (mph < 400) watcher.MovementThreshold = 4800;
else watcher.MovementThreshold = 9000;

Currently in my Android version of my app I make the following call one 
time when my location service starts...
locMgr.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, locLstnr);

That 3rd parameter is minDistance (now set to zero) which sounds very much 
like MovementThreshold in WP7.

My first question is: Can I throttle minDistance in my Android app the same 
way I throttle MovementThreshold in my WP7 app?
My second question is: What kind of call would be most efficient to do the 
throtting?  - would I just repeat the above requestLocationUpdates call 
changing the minDistance parameter?
Thanks, Gary

I don't know about "utility", but what I do is make my SVN repository
shareable on my home network, then make it available offline on my laptop.
Work anywhere you want, make any changes, then get back to your network and
synchronize the folder, and update your PC to the latest changes. Only
caveat is you have to make sure you only make changes in one place, or
conflicts arise that are difficult to resolve (in my experience).

What's the lowest SDK veraion that gets rid of these permissions? I'd like

[android-developers] Old versions still being downloaded from Google Play?

[Bram Stolk]

Hi,

In the Google Developer Console, when I look at my app statistics for 
'Daily downloads' I see something weird.
Most versions downloaded on the last day are currently available version.
However, downloads of old versions continue to this day, even the ones that 
have not been current for over a month.
What's up with that?
How come not every Google Play customer gets the current APK?

thx,

  Bram

Because you failed to put in a  element, or you have your
android:minSdkVersion set very low, most likely. This is one of the
reasons why the Eclipse new-project wizard sets up a reasonable
default  element.

What you are seeing are permissions that were added after Android 1.0
shipped and are "grandfathered in" for apps written to support Android
1.0.

Re: [android-developers] Mobile network idle sockets disconnected

[Robert Greenwalt]

3319 is fine.  It's just the tethering code noting an interface is going
away.

Can you get radio logs?  This is the system log - there are several log
buffers.  A bugreport (adb bugreport > mybug.txt) would get them all.  Then
you can match the connectivityservice dropout with what happened in the
radio.

I don't think you should open a bug: this is not an android issue, but
rather it's a samsung issue.

I have opened an internal issue to expand CTS to check for this - any
device wanting to claim to be an android device would not be allowed to do
such a thing in the future.

 If you send a packet every 6 minutes does that keep the device from
 pulsing connectivity?

 Can you take a bugreport - the radio log may have some indication of
 why it's happening.

[android-developers] Re: DDMS in Eclipse returning 0.0 in getBearing

[g...@deanblakely.com]

Bob,
Since I'm using DDMS you know that I'm running in the emulator on my dev 
box which, in my case, is a desktop computer.  The computer plus the 
monitor weigh quite a bit and I don't have a very long extension coord. 
 So, I don't think running is the solution.

BTW, you wouldn't happen to know the answer to my question, would you? 
hint: Bearing doesn't work in the emulator - always feeds 0.0.

[android-developers] Why does my Hello World app require three permissions?

[Andrew Pennebaker]

The SDK 
docssay 
that by default, Android apps do not request any permissions. However, 
when I generated a Hello World 
app, 
it requires three permissions:


   - android.permission.READ_EXTERNAL_STORAGE
   - android.permission.READ_PHONE_STATE
   - android.permission.WRITE_EXTERNAL_STORAGE

I have not asked for any of these. They do not appear in my 
AndroidManifest.xml,
 
nor do they show up when I grep my project. How are these silly permissions 
getting into my APK?

Re: [android-developers] Mobile network idle sockets disconnected

[Goncalo Oliveira]

Robert,

Thanks again for the feedback. I traced the logs from samsung with a simple
app to reproduce this behavior. Same thing, 6/7 minutes and it drops.
I posted the logs here: http://pastebin.com/FcPPbq3V
On line 3323 you can see ConnectivityService disconnecting. What I can't
understand is what's causing it. Line 3319 is suspicious as I don't have
tethering on, but other than that I can't really determine what causes
this. Should I open a bug for this?

Cheers

 Hi all,

 Seems that Android is dropping idle sockets when under a mobile
 network. Usually, no socket is kept alive for more than 7 minutes of
 inactivity. I am using a SIM card with a particular APN, that allows idle
 sockets for at least 30 minutes - this was tested using another kind of
 device, also communicating with GSM, and there are no drops, so problem
 isn't the SIM card.

 After a few searches in the web, I tried a few approaches to work
 around this, but until now, no success. I tried using a partial wake lock
 after connecting, releasing only when disconnected - didn't work. Also
 tried using only a 2G network, as some said that changing from network type
 could impact on this - same outcome.

 After digging a bit more and by analyzing logcat, I watched that a 
 CONNECTIVITY_CHANGE
 is sent after some idle time, disabling the data transfer availability
 (active network is mobile, no connectivity) and another one is sent
 enabling it again (active network is mobile, connectivity). This cuts off
 all live socket connections.

 Investigating a little bit more, I also observed that this behavior is
 not consistent through all Android versions, or maybe (even worse) through
 different hardware. Connectivity break is occurring in a Galaxy Tab 7
 with Android 4.0.4. The same isn't occurring in an Unitech TB 100 with
 Android 3.2.

 Does anyone know where I can get more information and/or I can work
 around this? I would really like to avoid sending heartbeats every 6/7
 minutes.


 Cheers

Try running real fast in one direction.  Then call getBearing while running.

[android-developers] DDMS in Eclipse returning 0.0 in getBearing

[g...@deanblakely.com]

I've been successfully using a KML file and DDMS to drive my app testing 
that uses LocationListener. So far I've just been using latitude and 
longitude which works well. But now I'm trying to use .getBearing and it's 
always returing 0.0 !!

Is this a bug in LocationListener? Is it a bug in DDMS? Is there a fix for 
it?

thanks, Gary

Re: [android-developers] Mobile network idle sockets disconnected

[Robert Greenwalt]

Is it possible something else on the device is occasionally sending data
and reseting your window?

I would look in the log for the timestamp of the ConnectivityChanged
broadcast and then check the radio log and see what's going on.

I suspect there is an unsolicited data call list notification coming from
the radio showing that the data call has gone away.  Perhaps just before
that there may be something explaining why.

You may have to contact samsung if you're sure that other devices have
longer connection times on the same carrier.

Re: [android-developers] Mobile network idle sockets disconnected

[Goncalo Oliveira]

Hi Robert,

Thanks for the reply. If I send a packet every 5/6 minutes the connectivity
is maintained yes. Only if connection is idle for longer than that. The
weird thing is that it's not an exact timer, even though the average is
very close. Sometimes it lasts 7 minutes, sometimes 8 or 9. I even saw this
happening with a 4 minute interval, though very rarely. On the other
device, I can most of the times maintain higher idle times.
I'll try to look at the logs more carefully to see if there's something
else. Is there anything in particular that I should look for?

Cheers

Re: [android-developers] Mobile network idle sockets disconnected

[Robert Greenwalt]

Android is not supposed to do this, though there is no guarantee of
connectivity.  It sounds like something samsung is doing, either
accidentally or on purpose.

If you send a packet every 6 minutes does that keep the device from pulsing
connectivity?

Can you take a bugreport - the radio log may have some indication of why
it's happening.

Re: [android-developers] give uniform variables an initial value

[bob]

The code is more like this:

int intensity_Handle; 

*…*

intensity_Handle = GLES20.glGetUniformLocation(mProgram, "intensity");

*…*

GLES20.glUniform1f(intensity_Handle, 0.5f);

Re: [android-developers] Mobile network idle sockets disconnected

[Goncalo Oliveira]

Hi Fred,

Thanks for the feedback. I'm currently implementing something like that, by
sending a heartbeat every 5 minutes (so far the safest interval on tested
devices). But this is not an optimal solution, as the data transfer plan is
a very tight one (particularly those including roaming). That's why our
agreement with the network operator allows idle connections at least for 30
minutes. Sending a heartbeat every 30 minutes is way better than every 5,
because even though the heartbeat is only one byte long, TCP overhead adds
another 66. That's at least 67 bytes every 5 minutes, at least 8h a day.

Cheers.

Re: [android-developers] Mobile network idle sockets disconnected

[Fred Niggle]

Hi,
I also experienced this problem, and found the solution was to use a timer
to send a character to the server every few seconds when idle.

I was lucky that i was also writing the server code sp i could work around
this.
Im not sure if this solves the problem your having, but just thought id let
you know of *a* solution.

Im flagging this in case i learn something new :)

Fred

[android-developers] Starting an actvity from Notifications

[dashman]

My app starts on activity A and can navigate to activity B.

I also have a background service and creates a notification.

Once the user taps on the notification, it calls A and then i create
a new activity B.

the problem is that if the user taps on the notification after the
user has navigated from A  to B - it creates a new instance of B.

So I have A B B.

Like to avoid that.

When activity A is activated by the notification tap - is there a way
I can detect that B is the top activity currently - so that i don't
create a new instance.

Also just out of curiosity, and since you keep mentioning this kind of
stuff - can you point me to the part of "The Java Language Specification"
that makes a name like 'intensity_Handle' non-compliant?  I just skimmed
through it again but could not find anything.  I mean, it doesn't start
with a number or contain white space, right?

[android-developers] Mobile network idle sockets disconnected

[Goncalo Oliveira]

Hi all,

Seems that Android is dropping idle sockets when under a mobile network. 
Usually, no socket is kept alive for more than 7 minutes of inactivity. I 
am using a SIM card with a particular APN, that allows idle sockets for at 
least 30 minutes - this was tested using another kind of device, also 
communicating with GSM, and there are no drops, so problem isn't the SIM 
card.

After a few searches in the web, I tried a few approaches to work around 
this, but until now, no success. I tried using a partial wake lock after 
connecting, releasing only when disconnected - didn't work. Also tried 
using only a 2G network, as some said that changing from network type could 
impact on this - same outcome.

After digging a bit more and by analyzing logcat, I watched that a 
CONNECTIVITY_CHANGE 
is sent after some idle time, disabling the data transfer availability 
(active network is mobile, no connectivity) and another one is sent 
enabling it again (active network is mobile, connectivity). This cuts off 
all live socket connections.

Investigating a little bit more, I also observed that this behavior is not 
consistent through all Android versions, or maybe (even worse) through 
different hardware. Connectivity break is occurring in a Galaxy Tab 7 with 
Android 4.0.4. The same isn't occurring in an Unitech TB 100 with Android 
3.2.

Does anyone know where I can get more information and/or I can work around 
this? I would really like to avoid sending heartbeats every 6/7 minutes.

[android-developers] make app compatible on 1024*720 px

Hi friends,

I have developed an app in a tablet of resolution 1280*752px  of 160 dpi,

I want to make this application work on a tablet of resolution  1024*720px
 of 160dpi.
I  referred the below link

http://stackoverflow.com/questions/5633792/android-app-support-for-multiple-tablet-screen-resolutions
and  I created 2 layout folders.

Can you please tell me how  am I supposed to go ahead with this. since
deadlines are nearing.

[android-developers] Re: onConfigurationChanged() is not called when flipping between landscape and reverse landscape?

[RS]

Hi Dianne, your answer isn't good enough. 
On flipping, the activity isn't informed through onConfigurationChanged 
(since Honeycomb, I suppose). This saves an unnecessary onSurfaceChange, 
texture loading, etc. Cool.

But in that case sensor manager too must provide values as in previous 
orientation. 
*Unfortunately it is mangled in accordance to the new orientation.*
In NDK, raw sensor vectors aren't officially available in sensor.h.

We use remapCoordinateSystem()[1] when away from default orientation.

We call this on config change to remember the new orientation and 
compensate for sensor value mangling. 
int rotation = activity.getWindowManager().getDefaultDisplay().getRotation()

Even without JNI such a call must be avoided except on config change event.

It is a overkill to (JNI-)call that on each frame just because the 
framework hides it from the activity but uses the new orientation in sensor 
value mangling. 

Framework must inform the activity of the change if it chooses to alter 
sensor values by the new (flipped) orientation. 

Thanks,
RS
[1] 
http://developer.android.com/reference/android/hardware/SensorManager.html#remapCoordinateSystem(float[],
 
int, int, float[])
ps: This is specific to flip... there is no switch between 
landscape<->portrait but just flipped as in landscape to reverse-landscape 
or portrait to reverse-portrait.
