Can you give more details as what are you trying to do?
If you making an app which does something on call receive, then for
sure you can virtually call your emulator so that you can test your
app.

>From command prompt you can call your emulator.

Thanks,

Re: [android-developers] layoutopt

[Romain Guy]

The framework supports both dp and dip, there's no reason to get rid
of either one. As for weight, ignoring the height/width is not a
solution. The weight is used to distribute the remaining empty space,
and the remaining empty space is computed by looking at the
width/height. The combination of width/height is also useful to impose
a minimum size. For instance width=200dip + weight=1 means "take at
least 200 dip and then the remaining space if available." This is
extremely powerful to create UIs that scale nicely across multiple
form factors.

Hey Romain,

Speaking of LinearLayouts and density-independent pixels can you proclaim 
once and for all whether, going forward, its going to be 'dip' or 'dp', or 
will the framework always support both?

Sort of back on topic, can linear layouts with weighting simply ignore the 
layout_[height|width] attributes?  I had a bitch of a time with a custom 
list view (horizontal and vertical) before I found (conflicting) info about 
setting the relevant layout attribute to 0dp.

[android-developers] Re: Wifi lock with WIFI_MODE_SCAN_ONLY

[seema]

Hello All,

   Here is what I do to scan on wifi while connected to 3G.

WifiLock wifiLock =
wifiService.createWifiLock(WifiManager.WIFI_MODE_SCAN_ONLY,
"MyLock");

if(!wifiLock.isHeld()){
wifiLock.acquire();
}

if(wifiService.isWifiEnabled() == false){
 wifiService.setWifiEnabled(true);
 }

Is my usage of WIFI_MODE_SCAN_ONLY is correct. When I enable Wifi,
it automatically connects to the remembered network. I just want
to scan but not connect. The definition of WIFI_MODE_SCAN_ONLY is:
In this Wi-Fi lock mode, Wi-Fi will be kept active, but the only
operation that will be supported is initiation of scans, and the
subsequent reporting of scan results.

Please help me

Regards,
Seema

[android-developers] Re-scaling PNG image to fit screen results in file about 2X the screen size

[Spooky]

Given the following code (indentation reduced to fit max line length):

---  CUT HERE  ---

// load and resize the original image
Bitmap image = BitmapFactory.decodeResource(getResources(),
mImageIds[info.position]);

// original size == w,h
int w = image.getWidth();
int h = image.getHeight();

// get display size in pixels --- this is the size we want...I think.
Display display = getWindowManager().getDefaultDisplay();
DisplayMetrics dm = new DisplayMetrics();
display.getMetrics(dm);
int nW =  dm.widthPixels;
int nH = dm.heightPixels;

// Calculate the scale factor
float sW = ((float) nW) / w;
float sH = ((float) nH) / h;

// do NOT fsck with the aspect ratio: make sure we scale at 1:1
if (sW > sH) sW = sH;
if (sH > sW) sH = sW;

// scale the image by the calculated scale factor
Matrix matrix = new Matrix();
matrix.postScale(sW, sH);
Bitmap resizedBitmap = Bitmap.createBitmap(image, 0, 0,
w, h, matrix, true);

// Load the resized image as wallpaper
try {
manager.setBitmap(resizedBitmap);
} catch (IOException e) {
e.printStackTrace();
}

---  CUT HERE  ---

As I understand this, based on reading the developers guide and
the examples for each item, this *SHOULD* take the original PNG
image, determine its dimenstions, determine the screen size,
calculate the scale factor (and make sure it's 1:1 to maintain
the correct aspect ratio), resize the original image to fit the
screen (again, keeping the original aspect ratio), and set it to
wallpaper.  Well, almost.

It is, in fact, rescaling the image to make it much larger (about
twice the size of the display on my Motorola Bravo---Android
2.2.1) than the window's dimensions.

I've been digging through this for over a week now, and finally
got this close tonight...but at this point, whatever it is, my
brain (with the aftermath of three tumors, triple brain surgery,
and radiation therapy, plus one chemo drug that is known to be
extremely nasty to the brain), will not allow me to see it.  It
does that sometimes, and it is incredibly annoying, to say the
least.

Can anyone please point me in the right direction?  What I'd
ultimately like to do is let the user select the desired
orientation (landscape or portrait), and resize to fit that
choice, and finally, lock (that might be the wrong word) the
orientation of the wallpaper to match the user's choice.

Thanks,
   --jim

Instead of a snarky answer, maybe you would realize that this could be
a problem for anyone who wants to coordinate the L&F of their app to
the platform's L&F.

So let me rephrase the question:  How can I provide resources that I
can select based on the UI skin/theme/whatever the user is running?

No, it's a date picker control.  I am displaying the textual date in a
non-editable field and invoke the date picker control when the user
presses the button.  It's a not fixed list of choices.

I had it that way originally, but it had become a nightmare to
maintain when there have been at least 4 different official Android
UI's.

The spinnner looks works great everywhere but the fact that the
TextView mocks around with the TextAppearance messes it up.

I might end up just moving the TextView into my app and remove that
behavior.

[android-developers] Re: Logcat View fails with "Could not create the view: For input string: "our" "

[Swati Goel]

I got the solution. I worked.

Solution is in your Eclipse workspace go 
to .metadata\.plugins\org.eclipse.core.runtime\.settings 

there is a file com.android.ide.eclipse.ddms.prefs

In this file there is an id which contains all the filters which you were 
using in DDMS.
You can compare that file with your colleague and find the difference.

I did the same and it worked.

Thanks

[android-developers] Re: Android LifeCycle and Singleton Instances

you can store the data to database or serialize the object.

I guess you need keep some data  or do something after app has been
stopped.

[android-developers] Re: onRestart from Home button or from back button

[albnok]

Have Activity B call Activity C using startActivityOnResult(intent,
requestCode), override Activity C's onBackPressed to pass a kill flag
via intent and setResult. In Activity B override onActivityResult and
see if the kill flag is there and the request code matches then call
finish(). So pressing back in C will go to A.

[android-developers] Re: Android LifeCycle and Singleton Instances

[Streets Of Boston]

The code below will work fine for a singleton:
...
private static MyObject myObject = null;
public static MyObject getMyObject() {
  if (myObject == null {
myObject = new MyObject();
  }
  return myObject;
}
 
Note that variable won't be 'reset' to null. There is nothing to reset when 
your process is killed. It is gone, nohting left.
 
When a *new* process is started, i.e. the process that will run your app 
again, then the static fields are all properly initialized (in this case, 
'myObject' to the value 'null').

It seems like what you need is a unit test. The default Android testing
framework only runs on a device (or emulator), but you can use
Roboelectric to test most things in your IDE. No device/emulator
involved, fast and easy.

Open a command window and type "java".  (Well, you'll probably have to
navigate to the correct directory and do a "javac" first, but it's not
much more complicated than that.)

Re: [android-developers] Re: Running activity with parameter from status bar notification

[Dianne Hackborn]

Do you actually have permission to run the activity that is in another
application?

For debugging issues, you should try to isolate your problem.  For example
here you should make sure that you can directly do startActivity() with that
Intent in your own app.  Once you have verified that works, then throw the
PendingIntent and status bar into the mix.

Also be sure to look at log output, because that often has useful messages
when things are going wrong.

Re: [android-developers] Android LifeCycle and Singleton Instances

[Dianne Hackborn]

If your process is killed, the next time you run a fresh process must be
created and re-initialized.  There is no way to get a "stale" pointer across
this.  If the pointer was stale, you'd probably have a native crash because
it would be completely unrelated to the current process you are running.

You can verify the behavior yourself just by using adb shell to kill your
process.

[android-developers] EditText and the unwanted Quick Search Box

[Eric Carman]

I have an app that uses an EditText for input and is very simple.



In the code I trap the OnKeyListener to listen for the enter key,
otherwise nothing else is going on with this EditText.

Problem (steps to reproduce):

1. Start the app.
2. Tap on the EditText to bring up the soft-keyboard.
> The keyboard displays as you would expect. The action is the return key.

3. Touch a letter on the keyboard ('n' for example).
> The Quick Search Box is brought up, the keyboard action changes to "Go". The 
> app isn't happy at this point.

It doesn't happen all the time, but I can reproduce it on a Nexus One
running 2.3.4. (I've reproduced it otherwise, but this is the only
device I currently have access to that reproduces it.)

Also, I do not use - setup - or anything else - with the qsb
functionality. It's not setup in the manifest or anything. This is
showing up all on its own.

Steps to resolve:

I've been refactoring the program, simplifying a lot of things in an
effort to locate this particular needle in the haystack. I've tried
various IMEOptions and InputTypes to no effect.

The app uses voice recognition. It turns out that when I comment out
the voice recognition code, the problem doesn't reproduce (yet?). I
don't have to have used voice recognition, just that it was set up for
use (in onCreate like the sample app) seems to be a sufficient
combination (unholy aliance?) with the EditText to cause this
behavior.

Question:

I really don't want to rip out Voice Recognition if I don't have to,
so I was hoping that someone has run into this issue and maybe has a
solution or suggestion. It's quite possible that this isn't the
solution, I just haven't had it re-appear. So looking for some sort of
rational explanation.

Thank you.

Best Regards,
Eric

[android-developers] Android LifeCycle and Singleton Instances

[Jake Colman]

I was pretty sure that I understood the Android lifecycle and how
applications/processes might be start/stopped/removed and how that
effects whether variables remain initialized.  I am, however, seeing
some funky behavior in my app such that I am afraid I have missed
something.

I use a singleton pattern for some of my objects.  That is, the
constructor is private and you call a static getInstance() method to
construct the object.  The static instance variable is, of course,
initialized to NULL which is the trigger for getInstance to know whether
the object needs to be constructed.

I have learned that any code that calls getInstance() cannot assume that
the object it has constructed continues to live in memory since my
application might have been killed by Android.  So throughout my code I
always call getInstance() to ensure that I have a valid object.  Am I
correct in assuming that had I been killed that getInstance() will
create a new object?  In other words, will my static instance variable
have been reset to NULL or might my factory method give me back a stale
pointer?

...Jake

[android-developers] Re: Show Text On Screen

[EdwardComb]

Thanks for your info.

I tried that but seems like the whole view changed. What I mean is
that what can i see
on the screen is just the text that was not running on top of my
application.

I google again and found out that we cannot straight away display text
on GLSurvaceView. (my mistake i didnt mention in the question)

Thus, I tried to bind the text as texture on an object like a 2D
square.
As a result:
1) My FPS drop from ~16 to ~3
2) My application crash.

any idea?

[android-developers] Re: EditText stops displaying characters as I'm typing?

[Eric Carman]

Testing seems to indicate that the work I was doing in the
OnKeyListener had some sort of impact, albeit intermittently.

I've modified the OnKeyListener to send a message to a handler and
that seems to keep everything in order. Since one of the things I was
doing in the listener, (when the enter key was pressed) was to set the
text of the EditText to an empty string. Perhaps this was just enough
to cause some trouble.

Thank you for your suggestion, it seems to have led me in a better
direction.

[android-developers] Re: Running activity with parameter from status bar notification

[ivan harmady]

Hmmm, but how should I use it??  I am not using any uri(i dont even
know what for is it). I only need to start an activity from the click
on the notification. But the problem is, i want to run an activity
from different application.
There are usually examples like  Intent notifyIntent = new
Intent(context, notify.class); -> but this is for notify.class in the
same application, but i want to run activity in different application.
When i use the example above it is ok and the notify.class runs, but
when i want to run the activity as i described in my code
-> intent.setClassName("com.iwaneez", "com.iwaneez.PlaceSettings");
nothing happens on the click.
Aren't there any permission or something else?? I really don't
understand why i cannot run it this way..

I really need this...pls help :(

Java is a compiled programming language. The flow you are describing
fits for an interpreted language, like Ruby.

If you package your application code in a JAR, you can load that JAR
into a JVM interpreter (JRuby, BeanShell, etc.), and try calling it.
You might be able to do this via SL4A, or possibly via the shell as
mentioned above.

That being said, this may take more time and headache than simply
creating a unit test suite, in large part because you may not have
access to enough of Android via whatever interpreter you use. JRuby
with Ruboto *may* give you enough scaffolding to try to do meaningful
experiments this way, and even that may only give you an Activity.
IOW, the sorts of things you are trying to test this way ("examples in
the reference page") are the least likely things you will be able to
actually test this way.

[android-developers] Result of two list adapters, merged in one View

[Arun N R]

Hi,
I have some code which executes two queries against a database and
returns two cursor objects. Is there any way that I can combine these
two cursors are displayed one after another in one view.

Currently one of the cursor is (Picked from samples)

Cursor c = mDbHelper.fetchNumber(searchNum);
startManagingCursor(c);

String[] from = new String[] { NumberDbAdapter.KEY_TITLE };
int[] to = new int[] { R.id.text1 };

// Now create an array adapter and set it to display using our
row
SimpleCursorAdapter notes = new SimpleCursorAdapter(this,
R.layout.notes_row, c, from, to);
setListAdapter(notes);

If I have one more cursor of similar type, how do we display the
output of these two in one view?

Please help.

This might be a bit much to ask, but, out of interest, am I correct in
saying it is impossible to have similar actions performed by the plain old
Android browser?

I could imagine an application which the user might start, which starts a
service, which if the browser loaded a page would allow interacting from
javascript to an object in aforementioned service.  I understand that this
is a bit contrived, because your process might be eventually killed, so I
presume that the standard thing to do in this situation is to add a receiver
to capture links of some form and hand them to your app instead.  However, I
can imagine uses for such functionality that don't fit into this model:
during some research in the last year I wanted to have multiple pages
throughout the net interact with an Android app that users would run in the
background, that does things like record information about browsing
interests.  Obviously this situation should be outlawed in real apps because
the idea that a rouge application could intercept HTML from any site the
user was browsing would be a *major* security hole, however this wasn't
something we were worried about (as, again, the app was used just for
research.)  My question isn't for that particular situation, as we can just
root the phone and hack what we needed, but in general.

There is no simple way to do this. With addJavascriptInterface() and
loadUrl() of a javascript: URL, you can get the HTML by brute force.

If what you want is the page content then there's no need for a webview -
just connect to the URL directly, read the contents, and do what you need.

Try going to the manage apps screen and finding the Market app. Then force
stop it, clear the cache and data, and uninstall any updates, if there are
any already applied. Reboot the device then restart the Market app. Give it
some time after that and see if that gives it a kickstart.

It's definitely possible.  Look at Tcl/Tk Wiki (http://wiki.tcl.tk) as an
example of how useful such a site can be.  It's an incredibly good
resource

> then it will solve a lot of newbie problems and be an extremely

If you look at the Tcl Wiki, you'll find that it can also go WAY beyond
just beginners like me.  I was once a beginner with Tcl/Tk, too...but for
the last 15 years or so, I've been developing and improving with new
features a freeware Tcl/Tk based hurricane tracking program called
JStrack (prn J S track).  It's online at http://www.jstrack.org/jstrack/
(site, domain name, system, system administrator, regular backups, backup
power, etc., provided by one of my users).)  The wiki and comp.lang.tcl
helped tremendously on the Tcl/Tk side, and NHC, NOAA, NWS, and a number
of hurricane researchers helped on the technical side, including all of
the maps (courtesy of Ron Murphy, NWS Birmingham).  The Tcl/Tk wiki has
topics ranging from just getting started, to stuff that's more for the
developers of the language itself.  I see (and hope) this wiki being very
much along the same lines, and I think that's what Raghav has in mind,
too.

Things the Tcl/Tk wiki has that, IMHO, this one could use:

1) "Example scripts everybody should have"

2) people who write packages, libraries, etc., post documentation
   on how to use it (commands, command-line args, one or more
   example(s), etc., and others comment, offer suggestions, fixes,
   pointers to similar or related pages on the wiki, etc.

There's more, but that's what comes to mind right now.  And again,
I'm mentioning the Tcl/Tk wiki, because I consider it a great example
to build from.  Just my opinion, of course.

> atleast someone and will grow at a slow but reasonable rate as some more
> people contribute. I am not saying that it will be ready by next week or

The Tcl/Tk wiki has now taken on a life of its own, and is a HUGE
resource that is likely to continue to grow for a long, long time.

Later,

[android-developers] Re: Android emulator bottleneck

[Streets Of Boston]

>From discussions with the Google Engineers, the emulator emulates the *entire 
*device on the lowest levels, not just the DalvikVM. It emulates the ARM 
processor and the code that runs on it and a bunch of the in and output 
devices (keyboard, touchscreen in some form, screen, GPS, etc). You can run 
NDK code (c/c++) on your emulator. 

They told us at Google IO (and other conferences) that the biggest 
performance bottleneck is the rendering of (large) screens. 

They are working hard in having the screen rendered on the PC's hardware 
(GPU) instead of doing it all in software (rendering the screen pixel by 
pixel). Some early demo was shown at Google IO and it looks very promising.

Yes there is. Intel has honeycomb running on their IA (Intel Architecture).

But Google TV runs on x68 and Google TV will upgraded to Honeycomb (3.1)

[android-developers] Re: Android emulator bottleneck

[jtoolsdev]

The docs are a little vague about any ARM emulation.  It says "the SDK
contains ARM machine code for the Android Linux kernel".  Would it use
that on Windows?  And then it wouldn't be the first time the docs are
left vague as we all know.  Seems to me if you are running Java byte
code then all you need is a layer for that but maybe not.  I don't
have to time to play systems engineer on top of application
developer.  That will make you a "jack of all trades and master of
none" in today's tech world. :D

But I do know that I read a response on this group from support that
the problem had to do with not being able to use the graphics card
acceleration on the PCs.  Someone will probably figure that one out
though.

I thought the Android Market app auto-updates? Even my G1 has the latest
version.

Distribute the application yourself, from your own secure Web site,
and hope none of your users redistributes the app.

You cannot update it except via an update to the firmware of your
device. Check with your carrier or with HTC to see if/when the Desire
is getting an update past your current version.

[android-developers] using native protocol buffer library does not work

[dom]

Hi everyone,

I've built the Google protocol buffer library (native c++ version)
into a static library using the standalone toolchain.  I modified the
HelloJni sample in the NDK development to use this library, but when I
go to run it on the emulator nothing works.

I created a small test library to check that I was doing everything
correctly and the test library functions correctly.  I was able to run
this from Eclipse and also using ndk-gdb.  When I went back to the
protocol buffer library, nothing ran anymore.  In ndk-gdb I could not
see any symbols or source.  The code just seems to hang somewhere.

I'm trying to build the code natively as we have developed a bunch of
software around it and are trying to avoid having to re-implement all
this software in Java.

Any help would be greatly appreciated.

Dominique

Re: [android-developers] Connection Issues

"server-PC" is not a valid domain name. getByName() uses DNS, as far as I know.

[Ashwath Kumar K]

Hi ,

I am trying to achieve a http streaming of mpeg2ts stream containing
MPEG4-AVC(H264) on Gingerbread 2.3.4 after upgrading my Nexus S to 2.3.4.
Playback was fine on 2.3.3,
Now I am getting the error has  "ERROR_END_OF_STREAM" from the stage fright

The same app works perfectly on honeycomb versions.

[android-developers] Android emulator.

[Dr.Bot]

I can't get the emulator to start under Ubuntu.  the android command
under /tools works and I created a AVD using the 3.1 platform with no
SD card - it refused to create a virtual device with any size SD card
I tried.  At any rate

I get a 'file not found'  when either cd to the directrory and
typing ./emulator  (with or without  -avd def31)  The virtual device
is created and is sitting in ~/.android/avd/.

The permissions look the same as for the 'android' command which
works.  Seems like a path/permission issue - but perhaps there is some
memory gotcha.  Running a 1gig laptop Ubuntu 10.  Latest eclipse,
Java, SDK.


BTW  I do have the hardware on the ADK working, now If I only had a
nice Xoom

http://www.youtube.com/watch?v=dh0BcO8yB1Y


Thanks  - I am new to this group -  but a search for emultor won't
start, won't run didn't come up with anything.

Also can I even run the ADK with an emulator?  Not sure if the USB
port mapping might barf.

[android-developers] App Installation Issue

[bigD]

Hi,

I've developed a Timer App that consists of 1 count down timer and 1 count 
up timer.  I recently installed it to my Droid X phone for the first time 
from by connecting my phone to my development box via USB, running the app 
from the Eclipse IDE, choosing my phone from the Eclipse device list.  The 
installation worked.  However, when I run my Timer App on my phone and 
another app runs concurrently, my phone freezes up and I have to pull the 
battery to unlock the phone.   For example, I was running my Timer App and 
while it was running, I received a text message.  This caused the phone to 
freeze up.  Another time, the Timer App was running, I opened up a web 
browser while it was running, and this caused the phone to freeze up.  

I don't know what's causing this problem as this is the first Android App 
I've developed and installed to my phone.  Under my phone's app settings, I 
have 'Unknown Sources' checked.  Under the phone's App Settings->Development 
settings.  USB debugging is checked, Stay Awake is Checked.  My app manifest 
file has debuggable set to true.

Please help.

Thanks in Advance,

Donny

[android-developers] OpenGL - CPU pegged

[Ratamovic]

Hi all,


When I run my application which embeds Irrlicht 3D engine to draw a 3D
terrain using OpenGL, a very strong slow-down happens very often. When
looking at the log, I can find this message:

05-31 09:53:39.480: WARN/SharedBufferStack(2580):
waitForCondition(LockCondition) timed out (identity=101, status=0).
CPU may be pegged. trying again.


I found a few threads about this problem but no satisfying solution
(http://groups.google.com/group/android-developers/browse_thread/
thread/d5b7e87f4b42fa8f/d6214ed7a02efc98?q=OpenGL&lnk=ol&). Basically,
it seems there is a lock happening when processing surfaces which
happen mainly on HTC devices (mine included of course)...

The only solution proposed is to call eglWaitGL before swapping
buffers which indeed solves "sudden and awful" slow-down problems but
which also "continuously" reduces the frame rate (FPS becomes barely
acceptable).


Any news on that or planned fix? Or maybe a better trick to solve it?

[android-developers] Integrated SIP Client on Nexus S: no 30 ms packetization supported

[sNi]

Hi,

when testing the integrated SIP Client on the Nexus S (Android 2.3.4)
against FRITZ!Box CPEs (highly spread WiFi/VoIP router across Europe)
we experience the following issue:

When placing an outgoing or incoming VoIP call over the CPE the
playback of the incoming RTP audio is scrambled. The outgoing RTP
audio is alright.
The reason for that is that the CPE uses 30 ms packetization for the G.
711 data. The audio playback works alright when the packetization is
adjusted to 20 ms.

As it is highly common here to have 30 ms packetization for G.711 we
badly need 30 ms support in the native SIP stack in android.
Is there any chance to get that support into the framework? Usually
that can be easely done by only adjusting the buffer size and allowing
30 ms packets to be received.
For the corresponding CPE it would be alright if received 30 ms
packets would be processed and still packets would be sent using 20 ms
packetization.

Thanks
Sven

[android-developers] Connection Issues

[Luiz]

Hello everyone.

I'm trying to connect with a computer (face it as a "server", I just
have to access a database) in my app, based on the computer's name. It
works fine with the IP, but I truly need to establish this connection
based in the hostname (the IP is not guaranteed to be static). The
computer is on windows 7.

This line of code keeps giving me an UnknownHostException
>> String ip = InetAddress.getByName("server-PC").getHostAddress();

That's where the weird stuff begins: it works perfectly if put
"www.google.com" instead of "server-PC". It also works if I try to get
the IP from a random non-android project in another computer in the
same local network.

I believe it's important to highlight the fact that I don't need a
connection with the Internet, just with my "local server", and that
I'm running my application in a real device, not in a emulator.

Thanks in advance,
Luiz

p.s.: sorry if something is not fully comprehensible because of my
english.

Questions regarding the use of a Google TV device are best asked of

[android-developers] Re: Creating a good reference point for Android

[Raghav Sood]

Hi all,

I have noticed how often there are questions regarding problems with the
market, in-app billing, documentation etc. It seems that the Android
references are spread very far and wide and in some places non-existant
alltogether. I plan to solve this bye creating a "Wikipedia" of all android
related topics. Two days ago I started the process and created the wiki at
http://wiki.androidappcheck.com/ Right now I am its only contributor and by
no stretch of imagination know all about Android. I would like it if all of
you people could help me with this. I have so far made only 9 pages in the
time it has been up and none of them are as detailed as I would like.

Please help with this project as it will be a good starting base for all
Android developers.
Thanks

That was my previous message which I think most of you missed.

Please help make this what I intend for it to be so that is\t is useful for
everyone.]
