If you have the rest of the code in place, I'd be reluctant to toss it out 
and start over with a SQLite implementation. Although it might do the 
conversion for free, it's going to be a much more general-purpose 
conversion routine, and thus is unlikely to be as fast as one you've 
optimized for your specific use case. You could put together a quick 
benchmark to see, but that'd be my expectation.

[android-developers] Geo Location and webview

2011-04-15 Thread Moose

I have a web app with a tool in it that uses google maps (the web tool, not 
the android one). On my computers web browser I test it and it works fine 
(gives a surprisingly accurate location, marked with a pin). However, when I 
try and use it in the webview within my app, it does not get a fix on my 
location or place a pin. Shortly after the map loads, I get the Location 
set by GPS notification (Android 3.0 XOOM), however closing the map tool 
and reopening it does not change the result.

I have setGeoLocation(true) and both fine and coarse permissions are enabled 
in the manifest.

I do not need the location to updated constantly, I just need it to update 
once (in the future I may wish to have it update every n minutes or 
something). I don't want to have the GPS running constantly, as that would 
be a battery drain. I have been disappointed by the lack of a supplied 
sample, and all of the tutorials I can find don't (appear) to apply to a 
webview.

Note: I do not currently have access to the source code for the webapp, 
however I do know that it uses this:
( http://code.google.com/p/geo-location-javascript/wiki/SupportedPlatforms )
I could potentially obtain the relevant code, however as the problem does 
not exist on a computer browser, or on the stock browser, I know that the 
issue is with my app.

[android-developers] Re: Android Debugger is DOG Slow

Sure, apps run slower when attached to the debugger, but that's hardly 
surprising given the overhead.

I have noticed that one of my apps seems to slow down more than the others, 
which leads me to believe that certain operations are more affected than 
others. It's never been problematic enough for me to dig further into it 
than that, but it might well be that your app is heavy on operations in this 
class. I'd suggest you profile a debugger run and post the results here. If 
it's something specific, it might well be something the toolchain folks at 
Google can improve upon for a future release.

[android-developers] Re: SQLite Open failed

I see a handful of these in my Dev Console error logs, but have never had it 
happen somewhere I can chase it down. Here's a typical stack trace:

android.database.sqlite.SQLiteException: unable to open database file
Caused by: android.database.sqlite.SQLiteException: unable to open database 
file
at android.database.sqlite.SQLiteDatabase.dbopen(Native Method)
at android.database.sqlite.SQLiteDatabase.init(SQLiteDatabase.java:1899)
at 
android.database.sqlite.SQLiteDatabase.openDatabase(SQLiteDatabase.java:881)
at 
android.database.sqlite.SQLiteOpenHelper.getReadableDatabase(SQLiteOpenHelper.java:168)

In one of my apps, where I ship a static database in /assets, I was able 
to work around this by catching the exception, deleting the offending .db 
file, then recreating it from my copy in the APK (same as I do on first 
installation). But you can't do that for user data.

In summary, I believe it's a platform bug, but nebulous enough that it's 
hard to create an error report for. :^(

[android-developers] Problem with Bouncing ListView

2011-04-15 Thread st0le

We have an application that has a listview which shows some contacts,
there are about 20 contacts shown at one time, and the user can use
the swipe gesture to move to the next 20, (or the previous) page

It works fine. Now, we've noticed Samsung (and maybe more) Devices
have augmented the listview to include a bounce effect, it lets you
pull (scroll) the Listview away from the border (leaving empty space
between the border and the first list item). When released the
listview kinda bounces on the top(or bottom) returns to normal.

Now, The actual problem.

The thing is when i swipe diagonally (orthogonally, it works fine), it
does 2 things simultaneously
1) pulls the listview to the middle
2) moves to the next page (shows a progress dialog and then reloads
the same listview with new records)

but the Listview doesn't retract to the top...instead it just stays
there in the middle (basically the bounce effect doesn't get a chance
to finish), to correct it the user has to scroll again.

It's hard to explain, if it's unclear i'll try and post a screenshot.

Any ideas how to make the bounce effect complete itself?

Thanks in advance.

[android-developers] Capturing screens and sending it across from a device to another

2011-04-15 Thread gaurang...@gmail.com

Hi,

I am trying to build an application which shares an android device
screen with another android device. Mainly the way VNC or Microsoft
remote desktop connection works.

To do this i thought to capture the screen of the host android device
and send it across to the secondary android device. The problem i am
facing in the implementation of this application is that i am unable
to get any native api to capture my screen. I searched and came across
a good utility in eclipse to capture the screen but that does not help
me in what i intend to do. It helps you get an image and store it in
your development environment. My requirement is to capture the host
screen and then send it across to a different device.

Going further i would like to discuss the my approach later once i am
through with this preliminary step of my application, :)

The vantage point of this application will be when a user while
chatting and discussing an application or a display feature they have
will be able to share the screen of their own devices with any other
user. The way we do it in general with mstsc, rdc, nautilus on linux
or vnc

Any help in this will be highly appreciated.

The problem is not due to Eclipse version but due to the outdate
examples on the internet particularly app-for-android
You can fix this by adding

 uses-sdk android:minSdkVersion=11 /

In the Manifest.xml file and copying the proguard.cfg file from a
blank project to the example project.

[android-developers] Use Google Spreadsheets API in Android

SpreadsheetService service = new SpreadsheetService(exampleCo-
exampleApp-1);
service.setUserCredentials(j...@gmail.com, mypassword);

URL metafeedUrl = new URL(https://spreadsheets.google.com/feeds/
spreadsheets/private/full);
SpreadsheetFeed feed = service.getFeed(metafeedUrl,
SpreadsheetFeed.class);
ListSpreadsheetEntry spreadsheets = feed.getEntries();
for (int i = 0; i  spreadsheets.size(); i++) {
  SpreadsheetEntry entry = spreadsheets.get(i);
  System.out.println(\t + entry.getTitle().getPlainText());
}

But that doesnt work in an Android Application because the gdata
library doesnt work with it.
So i have already know that i must work with the google-api-java-
client library..but i doesnt know how to make the conection with my
google docs account,like i have made above,but for Android ( working
with the  google-api-java-client library)

In the example here:http://code.google.com/p/gdata-java-client/wiki/
MigratingToGoogleApiJavaClient

We have:
HttpRequest request = transport.buildGetRequest();
  request.url = url;
  VideoFeed videoFeed = request.execute().parseAs(VideoFeed.class);
But in my own code i have:
HttpRequest request = transport.buildGetRequest();
request.url = metafeedUrl;
SpreadsheetFeed feed =
request.execute().parseAs(SpreadsheetFeed.class);
But SpreadsheetFeed is not a type of feed in this library.Wich kind of
feed i should have their?

Thank You

You have to load an additional driver for the specific device, look
for a pl2303.ko, which is the driver for your prolific converter. If
you cannot find it you have to compile it from the kernel sources.

I would be very interested in your findings, because I do some testing
with rs232 conversion on my zte blade. Communction with USB keyboard
and USB key work perfectly, but both converters I have are making
problems during communication.

[android-developers] Re: Database shared by Activity and Service. What's the best approach?

2011-04-15 Thread bogde

Thank you both for taking the time to reply.

I read about ContentProvider and also read the thread you gave me. It
definitely looks like CP is the best approach for me. So I will have
the service write data to the database via CP, and the Activity will
use CP to display data. I wonder if this adds any unneeded overhead to
the whole application. The application runs on a WM8505 based Chinese
tablet with only 128 MB of RAM. The purpose of the entire hardware and
software is to record and display two values. I really hope the
hardware is good enough for the requirements.

Thanks again!

 In the project settings is an Android entry. Under there is where you should 
 be specifying your build target. Try changing it to something else (like 1.6 
 or whatever) hit OK, the go back and change it again to what you really want 
 it to be. Maybe that will make it stick.

Thanks for the suggestion. I'll try this and let you know how it goes.

 There should be no need to manually set the Android library reference.

I agree.  :-)

 If all else fails, reinstall the SDK and / or Eclipse (making sure you have 
 at least 3.5 which the latest tools now require).

I have actually done this a couple of times already.  :-(  FWIW, I'm using 
Eclipse 3.6.

[android-developers] services

2011-04-15 Thread SIC

Hi,
I have a doubt about android services and how to properly use them. I
will formulate my question by firstly explaining a scenario of an
application.
1) The application has to get current data of different sensors and
networks such as GPS, acceleration, orientation, magnetic field,
bluetooth/NFC stream, gsm/wifi network information etc.
2) There could be 1 or more data streams monitored at once at a
different rate, for example monitoring GPS data would be at much lower
rate than acceleration, however all the values will be related after
that.
3) There are 2 modes: monitoring mode and recording mode. When using
the second one the application has to continue recording even after
main activity is finished(foreground service) until not terminated by
the user.

I would like to say that I have read all the documents on this and
also a lot of forums but didn't obtain any certain answers from that.
So I will divide this questions in some sub questions:

Q1) What is the bast way to do the monitoring part only which has to
share data between activities.
Option1: using parcelable objects to send between activities and
starting new Sensor/GPS Listeners on every new activity. (note that
there could be external blue tooth sensors which implies bluetooth
connection each time)
Option2: using a service which will collect all the data and current
statistics and share to activities

(Q2,3 and 4 are quite related.)

Q2) What is the best Service Approach in terms of stability and
performance (we don't want the service to get accidentally killed and
for example static variables lost).

Option1: Using a service on a separate thread using AIDL interface
Option2: Using a service on the same thread but start heavy processes
(such as bluetooth connection) on a separate thread inside the servise

Q3) What is the best way of communicating with a service
Option1: AIDL interface
Option2: callbacks to/from the service
Option3: Using a content observer
Option4: Using static variables in the service
Option5: Using messages

Q4) What is the best way of get announcements from a service
Option1: Callbacks from the service
Option2: Using a content observer
Option3: Using messages
Option4: Using Broadcasting


Again my aim is to consider for Stability and Performance, thus I am
looking for specific reasons why one method is better than the other.

Thank you for your help!

[android-developers] Programmatically play DTMF tones during a call

2011-04-15 Thread keithfry

I've read that it does not seem possible to play audio files while in
a phone call. However, I'd like to have an application play a DTMF
tone during a phone call. There shouldn't be any hw restriction on
this as the dial pad does this already when you press one of the
number keys. Instead I would like to have an application play this
tone automatically without requiring the user to touch the screen. An
example use case would be to recognize when the user has called their
voicemail number and automatically play the tones required to enter
their security code then begin listening to messages.

I've tried using the AudioManager.requestAudioFocus() to get access to
the voice call stream (AudioManager.STREAM_VOICE_CALL) but it always
returns REQUEST_FAILED. I can play the tone using ToneGenerator
without requesting audio focus, but it doesn't play over the voice
call just over the headset speaker.

Any suggestions?

[android-developers] Custom SeekBar View with x thumbs design

2011-04-15 Thread lmp

Hi group,

I'm trying to make a custom seekbar that can have more than one thumb
much like this one:
http://jqueryui.com/demos/slider/#range-vertical (mine should be able
to be both vertical and horizontal though).

I'm trying to get my head around how to start - I've already looked
into the existing Andriod SeekBar view and derriving from ProgressBar
view.
As I see it none of those fit the purpose 100%. So I decided to roll
my own.

I've extended the View class, and played around.
It would be nice to have features that let users set the
background,colors etc. attributes for the seekbar and thumb(s) both in
code and with xml.

I'm quite uncertain how would be the best way to design this and where
to start?
Any pointers will be greatly appreciated.

Thanks

[android-developers] C2DMBroadcastReceiver in Activity

2011-04-15 Thread nino

I have an application that uses C2DM notifications. I'm pretty new to
Android development because I think my problem is actually quite
simple and I just don't know how the android architecture works so
here it goes, I hope you guys can help.

What I did basically is copy the classes C2DMBaseReceiver,
C2DMBroadcastReceiver and C2DMMessaging from the chrometophone
project. I then created a C2DMReceiver extends C2DMBaseReceiver and
created the override events. The onMessage event works, as I added a
log entry to output the data I push to the device. Now I have an
activity and would like to pop up an alert box from the (already
opened) activity, as soon as a message is pushed to my device. I'm
really lost here, as I can't figure it out.

Google and many different forums/mailing lists are suggesting me to
initiate a BroadCastReceiver in the activity and override the
onReceive method. The problem is that the C2DMBroadcastReceiver has
declared the onReceive method as final, so there is no way to
overwrite it. So I started to think, that this is not the right way to
go...

I found some other example, telling me to send a broadcast from my
C2DMReceiver and watch this from my Activity, I think this sounds
reasonable, but I have no idea how to implement it.. Does anyone of
you have some examples on how to get started here?

[android-developers] [How To] Custom Component: hide parent class attributes

2011-04-15 Thread Nihal

Hello,

I am kind of new to android development and I am developing custom
components.
I implemented InputField that extends EditText but do some validation
according to class attributes ( I have done also the XML attributes
part)

My question is:
How do I extend a specific widget and hide some XML attributes, as I
want to put static value to them.
For example, I want to extend the EditText and make the InputType
field hidden so only me can set it in my class.

Thanks a lot,

[android-developers] Trying to load a list of overlay positions from file

2011-04-15 Thread matt h

Hi, I am trying to develop an app to list the bus stops for my local Public
Transit buses on a google map map,
but i seem to be having problem loading the overlay markers locations from a
text file

Heres the code i use to load a new overlay onto the mapview:


[CODE]
public void AddOverlayItem(int intLat, int intLong, String
strStop,String strType) {
 Toast.makeText(HelloGoogleMaps.this.getBaseContext(), intLat + , +
intLong + , + strStop + , + strType,Toast.LENGTH_SHORT).show();
 // TODO Auto-generated method stub
 ListOverlay mapOverlays = mapView.getOverlays();
 Drawable drawable = this.getResources().getDrawable(R.drawable.viva);

 if (YRT.equals(strType)) {
 drawable = this.getResources().getDrawable(R.drawable.yrt);
 }

 HelloItemizedOverlay itemizedoverlay = new
HelloItemizedOverlay(drawable,this);

 GeoPoint point = new GeoPoint(intLat,intLong);
 OverlayItem overlayitem = new OverlayItem(point, strStop, strType);

 itemizedoverlay.addOverlay(overlayitem);

 mapOverlays.add(itemizedoverlay);


}
[/CODE]


When i call the above code from a button i click from within my app all
works fine, settings get saved and marker appears on screen:

[CODE]
WriteSettings(HelloGoogleMaps.this,String.valueOf((int)(longitude*1E6))
+  +
 String.valueOf((int)(latitude*1E6)) +  +
  etStop.getText().toString() +  +
YRT);

AddOverlayItem((int)(latitude*1E6),(int)(longitude*1E6),
etStop.getText().toString(),YRT);
[/CODE]

But the problem i am having is when i call the following code at the end of
the onCreate method, my overlays do not appear:

[CODE]
public void RefreshStops() {
 // Refreshes the list of bus stop's
 //Find the directory for the SD Card using the API
 //*Don't* hardcode /sdcard
 File sdcard = Environment.getExternalStorageDirectory();

 //Get the text file
 File file = new File(sdcard,LocFile);

 try {
BufferedReader br = new BufferedReader(new FileReader(file));
String line;

while ((line = br.readLine()) != null) {
 String LineSplit[] = line.split();
 
AddOverlayItem(Integer.parseInt(LineSplit[0]),Integer.parseInt(LineSplit[1]),LineSplit[2],
LineSplit[3]);
}
 }
 catch (IOException e) {
//You'll need to add proper error handling here

Toast.makeText(HelloGoogleMaps.this.getBaseContext(),e.getMessage(),Toast.LENGTH_SHORT).show();
 }


}
[/CODE]

Contents of file being read:
longitudelatitudestopnumberbus-service

[CODE]
cat BusLoc2.txt
-79261518440062802511YRT
-79161518440062803243YRT
-79161518440062806465YRT
-7916151844006280675YRT
[/CODE]

I know the AddOverlayItem() method is being called from the RefreshStops()
method because i have put a 'toast' in the AddOverlayItem() method for debug
purposes and can see the info being passed to it correctly but for some
reason they are not appearing??

Any one have any idea why my markers are not being added?
Thanks for any help

[android-developers] Sending data continuously over NFC in mode P2P

2011-04-15 Thread azahara

Hello,

I have an android application that is intended to send data over NFC
in p2p mode based on the API demo provided by Android. I have already
tested the program using two Nexus S (both with android 2.3.3). The
program runs well; however it is possible to send only one message per
device in one tap. That is, I cannot send more than one NdefMessage
per tap. The only way to continue the exchange of new NdefMessages is
to put the mobile phones away and tap then again (but again only one
message is possible to send for the current tap).

I am using the enableForegroundNdefPush() and
enableForegroundDispatch() functions provided by the API to send a
message, and disable the corresponding functions in the onPause()
state of the activity. Does anybody know why should I have to tap many
times the phones in order to send continuously data in p2p mode?.
This behavior corresponds to a feature of NFC, that only allows to
send one message per tap, or a problem concerned with the management
of the intent sent to the application when a NdefMessage is received
more than once?

Any clue, I will thank a lot.

[android-developers] Creating scalable LinearLayout Background image

2011-04-15 Thread fr3sh

Hello,

is it possible to create a LinearLayout background image that
scales ?

As for the EditText widgets, I am able to create background images
(via draw9patch tool). There, I can define which image parts can be
(horizontally/vertically) stretched and which not. So the resulting
image is highly flexible.

LinearLayout background images do scale with the height/width per
default. But if my background image contains some sort of horizontal
line on the very top, this line is vertically stretched as soon as the
height of the Layout increases. Is it somehow possible to use
draw9patch to create a scale-intelligent background image?

Thanks in advance!

[android-developers] nexus s mifare desfire ev1

2011-04-15 Thread v.houba

Hello,

im trying out some new nexus s nfc functionality. since mifare
emulation is not (so far?) available for this device (or just
software?) im playing with proximity cards.
basically, i have a mifare desfire ev1 chip but for some reason i
cannot communicate it using NfcA.transcieve - im gettin IOException
with null getMessage().
Below is found the code i use. I can get valid id and techlist from
the tag. This code uses its own thread as well.

try {
Tag tag = 
intent.getParcelableExtra(NfcAdapter.EXTRA_TAG);

txtTagId.setText(Tools.getHexString(tag.getId()));
txtTagTech.setText(Tools.join(, , tag.getTechList()));

NfcA T = NfcA.get(tag);

T.connect();

final byte[] APDU_getVersion = new byte[] { 0x60 };

byte[] response = T.transceive(APDU_getVersion);

T.close();

// notifyAll();
} catch (Exception e) {
Tools.DisplayException(e, ctx);
} finally {

}

Do you suggest any changes to the code?

[android-developers] Correct way of accessing vibrator for haptic feedback in Andorid

2011-04-15 Thread Shreshtha

Hi, vibrator hardware is present in audio module and there is ASoC driver in
kernel for same.
In actual vibrator hardware (rotary) is connected to D class amplifier of
audio chip (similar to how headphones are connected).
set of alsa_amixer -Dhw set/sset vibrator commands ...  configures
(set the route, path, sound volume etc.) the vibrator and make it play.
I want to use vibrator for haptic feedback. How to link haptic feedback to
vibrator playback. Should I use ALSA APIs to perform same? Where should it
be placed in android dir structure?
I see one implementation using timed_output driver with sysfs interface
(sys/class/timed_output/vibrator/enable).
But accessing ALSA device from inside the kernel (from timed_output vibrator
driver) is prohibited.
(http://mailman.alsa-project.org/pipermail/alsa-devel/2011-April/038865.html
)

Please suggest

To make TLS connection using SSLSocketFactory between android App, it
takes more than 10 Sec.
(only the first time.. Once the it is completed,  no need to wait 10
sec to make a connection.)

I think TLS library has problem. but I can't figure it out.
Do you know how to make connection properly?

[android-developers] Re: How to export the project as a JAR file.

2011-04-15 Thread Dan

 You generally do not export the project as a JAR file.

 If you would take the time to explain precisely and clearly what it is
 that you are trying to accomplish, we may be better able to provide
 assistance.

I have a similar issue that I would have described the same way, but
I'll go with some details:

I have a nice .apk with a service and 4 activities, a shared native
library with some jni goodness, some drawable files in the res
directory and some other data in the assets directory.   Another
company would like to package the functionality of my .apk along
with their .apk so the user only has to make one download.

I would like to take their money with as small amount of work for
myself and their engineers as possible.  My current solution is to
send them a .zip file with all my classes, the assets, the resources,
and the native .so library, and the manifest, and my .mk files and
have them copy bits of the manifest into theirs, put the resources
and assets next to theirs, do the build process so the new R.java
is generated and then compile all my classes.

I would prefer not to give them the source code to my classes, but
the resources in R.java make that rough.  I do my builds through
ant on the command line, they use eclipse so there tends to be
some finger pointing when some functionality doesn't work.  Is
there a better solution than what I am currently doing and where
would I look for the details of what sort of things will bite me when
trying to pack files in a jar for someone else to reuse?  (E.g. is
there a workaround for providing a drawable ID for a notification?)

[android-developers] Re: Vertical text on canvas

2011-04-15 Thread Numeron

subpixel and antialiasing are both off for drawing the text, and the image 
is even drawn with a paint with both these off though it still appears 
antialiased anyway. Same result as drawing the image with a null paint.

I think that the canvas rotate uses its interpretation algorithm even for 
orthagonal cardinal rotations, when it should be translating directly. Seems 
a bit silly.

Re: [android-developers] Can we create UI component in a seperate XML file and load it

2011-04-15 Thread Robin Talwar

First create a class file not an activity and extend it with linearlayout
This will create your custom view .

Now lets suppose the package of your custom view is org.customView and class
is mylayoutfile.class

Then in the main.xml you can add this layout file just as you add a button,
textview or any widget but the important thing is how to write the name of
the widget.
Name of the widget will be the complete name of your custom view java file
like :-

org.customView.mylayoutfile android:id=
android:layout_width=...  /

instantiate this id in your main class

Dont forget to add constructors like :-

public NavigationBar(Context context, AttributeSet attrs) {
super(context, attrs);
}

public NavigationBar(Activity context) {
super(context);
}

This will be it now you just need to know how to iniflate it in your custom
view class :)

Re: [android-developers] Re: String to Float Performance Ideas


I haven't see the native part, but it's probably only useful for two things:

1 - Doing the final scaling by a power of ten, being able to handle very 
large or very small exponent values.


You could have your own lookup table for the range you need, say from 
10^-20 to 10^30, and use it when the final scaling factor is within this 
range. This would take just one floating point multiplication.


2 - To control the rounding behavior for this scaling.

This is a pretty expensive operation on the x86, as it involves 
saving/setting/restoring the FPU's control flags. Probably not much 
better on the ARM, if this is actually done.


It's important for 3D graphics (normals, intersections), but for 2D you 
can probably just let it be.

Re: [android-developers] Re: Database shared by Activity and Service. What's the best approach?


Two values?

Service running all the time?

Just put them into static variables accessible from both your Service 
and Activity classes. Back up into shared preferences or a file, so you 
can reload the latest values if/when the service/process is killed.

Thank you both for taking the time to reply.

I read about ContentProvider and also read the thread you gave me. It
definitely looks like CP is the best approach for me. So I will have
the service write data to the database via CP, and the Activity will
use CP to display data. I wonder if this adds any unneeded overhead to
the whole application. The application runs on a WM8505 based Chinese
tablet with only 128 MB of RAM. The purpose of the entire hardware and
software is to record and display two values. I really hope the
hardware is good enough for the requirements.

It can be assume such. If your code works fine now and the only thing you
want to change is the Manifest as said, then you can do it without risk. If
you are going to switch to Eclipse, you may want to try API Analysis plugin

Re: [android-developers] Re: How to export the project as a JAR file.

On Fri, Apr 15, 2011 at 3:03 AM, Dan dan.schm...@gmail.com wrote:
I have a nice .apk with a service and 4 activities, a shared native
library with some jni goodness, some drawable files in the res

company would like to package the functionality of my .apk along

I would like to take their money with as small amount of work for
myself and their engineers as possible.

How are you with a gun? You'll get free wallets along with the money that way.

:-)

My current solution is to
send them a .zip file with all my classes, the assets, the resources,
and the native .so library, and the manifest, and my .mk files and
have them copy bits of the manifest into theirs, put the resources
and assets next to theirs, do the build process so the new R.java
is generated and then compile all my classes.

I would prefer not to give them the source code to my classes, but
the resources in R.java make that rough. I do my builds through
ant on the command line, they use eclipse so there tends to be
some finger pointing when some functionality doesn't work. Is
there a better solution than what I am currently doing and where
would I look for the details of what sort of things will bite me when
trying to pack files in a jar for someone else to reuse? (E.g. is
there a workaround for providing a drawable ID for a notification?)

Well, the best answer would be an Android library project:

http://developer.android.com/guide/developing/projects/projects-eclipse.html#SettingUpLibraryProject
http://developer.android.com/guide/developing/projects/projects-cmdline.html#SettingUpLibraryProject

I do not know how well that handles NDK stuff, and my memory is fuzzy
on assets. The rest would be no problem.

Initially, you will wind up with stuff that will look like that you
need to ship Java code. However, there are workarounds for that.
Quoting myself from one of my books:

Android library projects are designed for distributing source code.
That may or may not be palatable in all cases. You can create a
binary-only library project via the following steps:

-- Create an Android library project, with your source code and such —
this is your master project, from which you will create a version of
the library project for distribution

-- Compile the Java source (e.g., ant compile) and turn it into a JAR file

-- Create a distribution Android library project, with the same
resources as the master library project, but no source code

-- Put the JAR file in the distribution Android library project's
libs/ directory

The resulting distribution Android library project will have
everything a main project will need, just without the source code.

You may also want to use some sort of unique prefix on your resource
files and names, so that you do not accidentally collide with a
project that is using your library.

Re: [android-developers] How to run my applications more efficiently

Leave the emulator running. Eclipse, at least, will deploy to the
existing running emulator rather than start a new one. A normal
development day would have you start the emulator once in the morning
and leave it run all day.

 When I was using Eclipse or IntelliJ to run my own android

 you guys have any idea on how to reduce the cost on starting the
 emulator or some ways to deploy my applications without reboot the
 emulator, please? Thanks a lot in advance.

Re: [android-developers] Programmatically play DTMF tones during a call

 I've read that it does not seem possible to play audio files while in
 a phone call.

You can play audio files while in a phone call, but they only come out
the earpiece or speaker of the phone your app is running on. The only
way the other end might hear it is if you are in speakerphone mode,
and I don't know how murky that turns out.

 I've tried using the AudioManager.requestAudioFocus() to get access to
 the voice call stream (AudioManager.STREAM_VOICE_CALL) but it always
 returns REQUEST_FAILED. I can play the tone using ToneGenerator
 without requesting audio focus, but it doesn't play over the voice
 call just over the headset speaker.

 Any suggestions?

What you want is not supported, sorry.

Re: [android-developers] Capturing screens and sending it across from a device to another

This is not possible with an ordinary SDK application.

 The problem i am
 facing in the implementation of this application is that i am unable
 to get any native api to capture my screen.

Correct.

[android-developers] Re: Backward compatibility when compiling.

 Ok, so you got the real reason :) In this case you have to use higher SDK as
 I am not aware of any other trick you could use for Manifest to add new
 attribute and still be able to build against older SDK.


I have the real reason yes but if this reason will damage backward
compatibility
I will prefer to forget this real reason.

 If your code works fine now and the only thing you
 want to change is the Manifest as said, then you can do it without risk.

You are talking about obfuscation now or about compiling with SDK
Level 8 and maintain compatibility with Level 4?


 If you are going to switch to Eclipse

We have too many to do with Netbeans, I will not switch to eclipse
only for Android since I don't feel the necessityu :)

Re: [android-developers] Native PDF Viewer

No.

 And if don't have, he has a lib native that can I work easily with
 PDF.

Android has nothing built in for PDFs. Some Android devices ship with
PDF viewers, but they are not part of the operating system. There are
third-party libraries available (e.g., vudroid) that you are welcome
to experiment with.
