Re: [android-developers] Re: more SMS questions

[Francisco Dalla Rosa soares]

if the ammount of data you wanna send is small enough to consider using SMS
as your medium you should just use App Engine or Heroku and it's gonna be
free. If you use more than the free limits of Heroku and/or App Engine that
means you really don't wanna do it through SMS for the sake of your users
(not everybody has a unlimited messages plan)



(Encapsulating TCP/IP network traffic in SMSes reminds me of when I was 15,
doing "data transfer" by running with a bunch of floppies from my house to
my friend's. whenever I had a corrupt packet - broken floppy - I'd have to
go back home and rebuild them)

Re: [android-developers] Re: more SMS questions

[Kristopher Micinski]

Using SMS just seems like a bad idea to me.  Pretty much everyone who
does this sort of thing uses a web backend (and the others don't work
well).  Seriously, using sms is going to be hackey and weird.  You can
try to Bluetooth, but my opinion (after trying it for this purpose) is
that using a server based solution is going to be much better long
term.  There are some free web backends popping up here and there.
Google "parse android" to see an example of one I've heard of but
haven't had the chance to use yet.

I agree that it seems like there should be a better way to communicate
between multiple people in your apps, but I think that right now, the
API support is limited to these third party sources (and a few make it
look fairly painless, besides, web backends give you a lot more
scalability).

Remember to design your app so you don't murder the battery life of the device.

Re: [android-developers] First Question ... be gentle

[Francisco Dalla Rosa soares]

Just to make it clear, that's an "Annotation" not a comment.
Comments are ignored by the compiler, annotations are actually evaluated by
the compiler in compile time and sometimes during runtime too.

http://download.oracle.com/javase/tutorial/java/javaOO/annotations.html

from the documentation:

Annotations have a number of uses, among them:
> Information for the compiler — Annotations can be used by the compiler to
> detect errors or suppress warnings.
> Compiler-time and deployment-time processing — Software tools can process
> annotation information to generate code, XML files, and so forth.
> Runtime processing — Some annotations are available to be examined at
> runtime.

Where are you copying the strings? If you are copying them to a resource
XML file (as you should), the encoding is UTF-8 so it should work
automatically.
If you are copying those in your source files as Java strings, you need to
change the encoding of your source files to UTF-8 (the default is the platform
default encoding): right click your project, select 'Resource' on the left
and change 'Text file encoding' to UTF-8.

Sorry if this is a little off topic (it's more an eclipse questron than an
Android one, but as it's for an Android project...)

What the easyist way to define non Latin text (I.e. Unicode) specifiy
Arabic and Chinese in an Android project? When I try and copy and pasted
the google translated version of my strings (I accept GT isn't the best way
to internationalise an app but my budget is zero so...) eclipse doesn't

Re: [android-developers] Compound Component not getting onKeyDown onKeyListener events for Droid Bionic or X2

Have you tried using the stock soft keyboard on those devices?  It is
possible for an IME to not do this interaction correctly, though a
manufacturer certainly shouldn't ship a device with such a problem.

Re: [android-developers] Re: Framework Cloning of Referenced Objects?

[Dianne Hackborn]

Generally a CursorLoader monitors for changes to the underlying database,
and delivers a new Cursor to you when the data changes.  So you could
certainly be putting new objects in mPeople if the contacts change.

Yes but a web service / backend needs a separate server and I wanted to have

If you mean "a subset of the Java SE class library" or something like
that, it is to save on firmware space and maintenance, if I understand
correctly.

Re: [android-developers] Can we use a scrollview inside linear layout?

Yes, the ListView does automagically scroll as the number of items
increase larger than the display area.

[android-developers] Re: Framework Cloning of Referenced Objects?

[Jay]

I really don't do much else with mPeople, though I can think of two
other things it might be. As I said, mPeople does supply a
ListAdapter. Is it possible that is doing some behind the scenes
cloning? Perhaps more likely, mPeople is populated by a CursorLoader
attached to the Contacts content provider. I am not 100% clear on the
semantics of loaders (I've been working from the docs and from
examples), so maybe something I'm not accounting for is triggering the
loader to asynchronously refresh mPeople. To be safe I guess I should
throw in a class to loader.stopLoading() once mPeople has been
populated.

Re: [android-developers] Compound Component not getting onKeyDown onKeyListener events for Droid Bionic or X2

[Eric Carman]

Hello Dianne,

Thank you for responding. 

The custom compound component I am using wants single character entry. The 
inclusion of TextViews in the component is a convenience and they will only 
show a single character at a time. The user doesn't directly interact with 
them, but with the overall component.

I don't want full interaction with the IME such that I get candidate text. 
I just want to capture the character they are entering - which has worked 
for all other devices I've tested - up through honeycomb. It's just these 
couple of devices which are behaving differently. The app is a puzzle app 
and the user interacts with it a character at a time.

Of course, the onKeyDown isn't even being called in this case, which is at 
the root of the issue I'm trying to understand.

I don't know if this helps to explain it any better. 

Thank you for the links. I will be looking into those very carefully. As 
always, your help and participation is really appreciated.

Best Regards,
Eric

Re: [android-developers] Can we use a scrollview inside linear layout?

[KK]

Thanks for the quick tip, I'll try it out. I've a question though. Is it
the case that the lisview inherently supports scrolling when the no of
items grows bigger than the display area, and hence we don't need to sue
scrollview in this case? If that is the case then, as per your suggestion,
in my case if the no of items is say 50 then they will automatically be
scrollable, right? Please rectify if I'm wrong.

Thanks,
kk

Re: [android-developers] Re: Framework Cloning of Referenced Objects?

[Dianne Hackborn]

Well as far as I know ArrayList won't just do this behind your back.  I
would assume there is something else your app is doing that isn't shown
here.  Are you sure you never change what is in mPeople that could cause a
new instance of an object to be created?

[android-developers] NoHttpResponseException when communicating between two emulators

[Weikang Wan]

I have a client (Emulator A, 5554) sending Http Request to a server
(Emulator B, 5556) which listening on 8102 port

1. I used "adb -emulator-5556 forward tcp: 8202 tcp:8102" to map port.

2. I then used URI "http://10.0.2.2:8202"; to send http request,
however, the exception is thrown:
"org.apache.http.NoHttpResponseException: The target server failed to
respond"

When I debug the server side, no request is received there.

Anyone has ideas about this problem?

Thanks,
Vycon

Re: [android-developers] Can we use a scrollview inside linear layout?

[Dianne Hackborn]

Yes, you can, but you really should use a ListView instead of a ScrollView
if you have a lot of items to show or the dynamically change.

On the top view use android:layout_weight="1" and
android:layout_height="0px" to tell it to grow to fill whatever space is
available.

This is confusing.  If you are using onKeyDown() etc to interact with the
IME, you are relying on the backwards compatibility behavior where the view
is not implementing the real InputConnection protocol but relying on the
IME to send simulated hard key events to it.  This has never allowed for a
full interaction with IME, and I don't think it has ever allowed for
completion choices because you are not giving it a way to show candidate
text and such as the user interacts with the keyboard.

If you want a full interaction with an IME, you really should implement the
InputConnection protocol.  The easiest way to do this is with TextView (it
is definitely a lot more complicated than getting raw simulated hard key
press events), but you can implement it yourself.

At the very least, you need to make sure you implement
http://developer.android.com/reference/android/view/View.html#onCreateInputConnection(android.view.inputmethod.EditorInfo)
to
tell the IME the type of text editing it should do for your view by filling
in the EditorInfo.  The
http://developer.android.com/reference/android/view/inputmethod/BaseInputConnection.html
is
provided to help with implementing an InputConnection.

[android-developers] Re: Compound Component not getting onKeyDown onKeyListener events for Droid Bionic or X2

[Eric Carman]

I've created a sample project that demonstrates the issue. I've tried to 
make it as simple as possible.

When executing the app, There will be a single instance of the compound 
component which includes two letters, one over the other. (A/Q) For clarity 
sake, the 'A' is Yellow and the 'Q' is gray. Long-press on the 'A' and you 
will bring up the soft keyboard. As you select letters from the soft 
keyboard, the letter 'A' should change. 

My continued thanks for those who are reviewing this.

[android-developers] Re: Can't layout square ImageButtons

[RLScott]

OK, I found a solution.  I do this in onCreate:

LayoutParams lp = button1.getLayoutParams();
lp.height = dispWidth / 5;
button1.setLayoutParams(lp);
button2.setLayoutParams(lp);
button3.setLayoutParams(lp);
button4.setLayoutParams(lp);
button5.setLayoutParams(lp);

where dispWidth and dispHeight were previously set by

Display display = getWindowManager().getDefaultDisplay();
dispWidth = display.getWidth();
dispHeight = display.getHeight();

also within onCreate.

This solution lets the layout_weight="1" and scaleType="fixXY"
properly scale down the image and divide up the width (which just
happens to be equal to the full dispWidth) and then I change the
layout params to include a calculated dispWidth/5 to be used as the
height, replacing the "50px" default.  This leaves the buttons always
square and always exactly filling up the bottom of the display

[android-developers] Can we use a scrollview inside linear layout?

[KK]

hi All,
I'm not sure if the asking I'm asking is logical or wrong. Actually I'm
trying to achieve something like this:
1. The whole screen is divided into two parts, Upper half which takes 90%
of layout space and the lower half which is 10% of the space.
2. In the lower half I'm showing the progress bar for each song selected
from the Upper half.
3. In the upper half I'm trying to show all the songs in the sdcard
available. I'm trying to make this part scrollable as we can have lots of
song which wont fit in the given space.

I want the lower part to remain fixed irrespective of the current selection
in the Upper half, say for example if I'm playing the 50th song(out of 100)
then song will be in the middle of the Upper screen space where as the
lower half will continue to show the current song position.

Logically, I'm trying to do something like this in the layout file



  layout_weight=9
  sldjfsldf
 
   song lsit
 
 ..


 layout_weight=1
   sdljfsldjf





Please help me how to get this done. Would appreciate other ways of
achieving my end result by some other elegant approach.
Thanks in advance.

Regards,
KK

[android-developers] Proguard problem

[André]

I have  a problem when I'm trying to export my project in eclipse.
While trying to create the apk gives me this error.
What could cause this?

[2011-11-06 17:29:50 - Project- X] Proguard returned with error code

Re: [android-developers] Re: more SMS questions

[John Goche]

After some browsing I found this thread:

http://groups.google.com/group/android-developers/browse_thread/thread/3b8dc90cdc701f49/9bcf1c15f2c52fc2

Apparently to use ports you have to set up a server and listen on that
port on the receiver.

Also, the GTalk API is now obsolete I gather. It would been a good
alternative since I only need to communicate
among android devices but it's no longer available.

Now I'm considering using something else like wi-fi as it would be
less expensive and above all probably
has an API that works unlike sendDataMessage, and SMS may also be
slower than wi-fi (and more unreliable).

http://developer.android.com/reference/android/net/wifi/p2p/package-summary.html

for the cell phones to communicate. However I'm not sure of the
network coverage for wi-fi.
If a user pays a fee can that user have wi-fi just about everywhere
the user goes?

I need to have a bunch of android phones send and receive data to each
other to communicate,

Suggestions welcome,

Thanks,

John Goche

[android-developers] Re: Compound Component not getting onKeyDown onKeyListener events for Droid Bionic or X2

[Eric Carman]

Apparently, Motorola has a developer's program called MotoDev (free) which 
gives you access to some potentially interesting tools. They have a Droid 
Bionic SDK addon that can be set up as an emulator.

I installed it this morning and I can reproduce the issue that my customers 
are seeing with this app. Interestingly, when I look at the logs, I'm 
seeing the following in response to a keypress:

11-06 10:28:16.632: INFO/AwesomePlayer(42): reset_l

Perhaps this is an artifact of the emulator, but at least in this case it 
would appear that all keyboard input is being redirected to a media play 
which is unprepared to handle this.

And the weirdness continues. Any insights?

[android-developers] Re: Can't layout square ImageButtons

[RLScott]

No, that won't work because the 4 views will expand to take up the
extra room, leaving the ImageButtons only as wide as their layout
width of 50px.  I don't want that.  I want the buttons to expand to
take up that room.

[android-developers] Re: EGL/OpenGL ES Frame Rate Stuttering

[Ratamovic]

Hi,

I got the same results on my phone (HTC Desire) and tablet (Galaxy Tab 10.1 
too) with a completely native application (implemented with NativeActivity) 
which was doing almost nothing apart from clearing and swapping buffers... 
So I doubt this issue comes from a garbage collector problem.
I would be really interested to know the answer. The only lead I have is 
the following question on StackOverflow: 
http://stackoverflow.com/questions/3706786/htc-desire-specific-opengl-es-1-frame-rate-cant-get-it-right

Re: [android-developers] Can't layout square ImageButtons

[Kostya Vasilyev]

Don't set layout_weight=1 on the buttons.

Insert four Views between the buttons to act as spacers, and give those 
layout_weight:











etc.

The layout_weight="1" is necessary to make the buttons spread out

The layout_width and layout_height are arbitrary, but they are

the scaleType of "fitXY" is necessary to make the image scale down to

Re: [android-developers] Re: more SMS questions

[John Goche]

Hello,

I have tried using Base64.encode() with the sendDataMessage as follows:

smsManager.sendDataMessage("5558", null, (short) 1500,
Base64.encode("hello SMS".getBytes(), Base64.DEFAULT), null, null);

I have also tried putting the following in my AndroidManifest.xml but
no luck on the emulator.


  





  


The result is the following output in adb logcat when the message is
received (some garbage is shown
as a notification as the text message arrives):

V/Telephony(  295): getOrCreateThreadId cursor cnt: 1

However I don't see the calls from my boardcast receiver being called.
I don't understand why it's not being called.

Any ideas?

public class SMSReceiver extends BroadcastReceiver {

  @Override
  public void onReceive(Context context, Intent intent) {

Log.d(TAG, "hello received");

Object[] pduArray = (Object[]) intent.getExtras().get("pdus");

SmsMessage[] messages = new SmsMessage[pduArray.length];

for (int i = 0; i < pduArray.length; i++) {

  Log.d(TAG, "received");

  messages[i] = SmsMessage.createFromPdu((byte[]) pduArray[i]);

  Log.d(TAG, messages[i].getDisplayOriginatingAddress());

  Log.d(TAG, messages[i].getMessageBody());

}

  }

  private static final String TAG = "SMSReceiver";

}

Many thanks,

Regards,

John Goche

[android-developers] Re: No APK file or DEX files are created - with no warning or Error whatsoever

[rktb]

With the new ADT plugins, it is the default behavior (to speed up
build time) to not generate the .apk on every build. Note that a build
is triggered every time a file is changed and saved as well and this
dramatically increases the build time. So, the change is to skip the
resource packaging step by default. You can generate the .apk by doing
a File --> Export --> Android --> "Export as Android Application" ...

You can also restore the original behavior of generating the .apk
automatically. More information on that is shown here:
http://tools.android.com/recent/finercontroloveradtbuildprocess

Re: [android-developers] Re: more SMS questions

[John Goche]

Tank you for your reply...

What do you mean base64 encode the binary data and send it as a plain
SMS text message?
But I don't want the message on the receiving end to go to the inbox
folder. I just want it to be
read by the application and discarded thereafter (class 0) or
otherwise use a port number that
my application can recognize. Can I do that if I simply base64 encode
my message and send
it as a multipart text sms? What about getting a status report?

I've read some posts saying sendDataMessage is broken on the emulator.

Still wondering what getSubmitPdu is used for.

John Goche

Try androidquery lib at androidquery.com. There is example and a demo
app to show you how to load images efficiently.

[android-developers] Re: contacts first and last name

[hongbosb]

_ID in data table and contacts table are two different things. So you
should use raw_contacts_id instead of _id when query in data table.

change
String[] projection = new String[]
{ContactsContract.CommonDataKinds.StructuredName.GIVEN_NAME,ContactsContrac
t.CommonDataKinds.StructuredName.FAMILY_NAME};
String where = ContactsContract.CommonDataKinds.StructuredName._ID+ "
= ?
AND "+ ContactsContract.CommonDataKinds.StructuredName.MIMETYPE+ "
= ?";

to
String[] projection = new String[]
{ContactsContract.CommonDataKinds.StructuredName.GIVEN_NAME,ContactsContrac
t.CommonDataKinds.StructuredName.FAMILY_NAME};
String where = ContactsContract.Data.CONTACT_ID " = ?
AND "+ ContactsContract.CommonDataKinds.StructuredName.MIMETYPE+ "

Re: [android-developers] ERROR/AndroidRuntime(631): FATAL EXCEPTION: main, ERROR/AndroidRuntime(631): java.lang.StackOverflowError

[lokesh gupta]

Looks like there is sonme problem in below snippet:

while ((strLine = br.readLine()) != null)   {
  String[] temp;

  strLine = strLine.trim();
  temp = strLine.split("\\s+");

  commonNameTable.createCommonName(temp[1], temp[0]);
  }

Check the temp values once again, may be because of trimming it is
giving the error.
