[android-developers] Couldn't get connection factory client

[Ian]

Help!!

I cannot release my app because Maps aren't working in the released
version.

I believe I have the right maps signature, which I added after setting
up my private key, then recompiled and signed.  Everything works when
I run in Debug mode, although I get a "dalvik" error whcih I get rid
of by reloading and rebuilding, as suggested by people in other
threads.

A grid of X'es appears most of the time, but I do sometimes see an
image of Africa which leads me to believe the signing was correct.

However, I see these error messages:

07-11 05:13:48.969: ERROR/ZoomButtonsController(776): Cannot make the
zoom controller visible if the owner view is not attached to a window.
07-11 05:13:49.379: ERROR/MapActivity(776): Couldn't get connection
factory client

I'm using Eclipse Galileo, SDK 1.5_r2 and ADT 0.9.

thanks!!!

[android-developers] How to make ImageView fill vertically within RelativeLayout

[an0]

I put an ImageView and a TextView within a RelativeLayout, and want
the ImageView to grow vertically with the line number of TextView. The
drawable of the ImageView is a png picture of vertical bar.

With the following layout, the ImageView does not fill the height of
the RelativeView. Instead, it alway keeps the original picture's
height.

Why does it not work as I expect?

[android-developers] ACCURACY_COARSE and ACCURACY_FINE

[Maps.Huge.Info (Maps API Guru)]

I've been toying with these two concepts for a while and was wondering
what the consensus is on how to handle accuracy changes.

I would like to be able to use the FINE but if not available use
COARSE. The issue is how to handle these two. I thought about using
two listeners and that seems like a good idea but it seems a bit of
overkill if there is a simpler method.

Any ideas? Code examples?

Thanks in advance.

[android-developers] Re: How to obtain bitmap from data in onPreviewFrame method of previewCallback and display on surface using canvas

[newbyca]

you need to tell me a little more about the issue ... but my guess is
you were seeing something like "Bitmap to big for allocated memory" or
something or other? i forgot exactly, but i've seen an error like that
before trying to write to bitmaps. again, this is just a guess, but
are you creating a new Bitmap object in each call to onPreviewFrame?
If so, that's a no-no :)

Instead, make your Bitmap class scoped and flush it out each time.

I don't like how it "ignored resource" ... that file has the guts of
my app...

again, refresh and build afterwards works but it signs with debug api.

export wizard doesn't work unless I do the refresh/rebuild
("missing .apk")

your help is greatly appreciated... I am recently unemployed and need
a new source of income... you're helping a man learn how to fish
instead of suck on society... thanks

[android-developers] Re: Low accuracy of the accelerometer Sensor

[newbyca]

D, I'm having many of the same issues, though my app is a little
different in nature ... i don't know that this will help much, but
here's my thoughts so far:

- when determining the sample time rate use event.timestamp in your
sensor listener callback. you'll see more or less the same results,
but more accurate all the same.

- i found the same with subtracting G from the three acceleration
components, that is, you can't rely on SensorManager.GRAVITY_EARTH,
you're better off having your app calibrate a local G on each handset.

- note that when filtering out G you need orientation data as well.
this posed a problem for me though: SensorManager has a method,
getOrientation, however I couldn't get it working. So instead I set 2
listeners, one for accelerometer and one for orientation ... meaning
when I filter G, i don't really know that I'm using the right
orientation data to calculate the different components of G because
the two callbacks are called independantly, so I can only make a best-
guess based on event.timestamp. How are you filtering out G?

- there's a simple free app on the market called "Accelerometer xyz
values" or something like that, just search for "Accelerometer" ...
gives a simple line chart of all three accelerometer axiis over time.

- from what i found around the net, this is a common issue with
accelerometers, even the more sophisticated ones used in robotics, tho
i couldn't actly find specs on the accelerometer used in G1. but don't
be too mad at HTC, i'd imagine iPhone has similar issues :)

- as for noise filtering, up to now i've tried a simple High Pass
filter. In this case, I set the device down flat and allow my app to
measure the range of noise coming from the sensors to create a
threshold. Then I only admit values with a higher absolute value than
the the threshold. I just built this app this week and so far have had
mixed results tho.

Now for Kalman filtering. I do have a little experience with Kalman
filtering and here's some issues to consider:
1) *performance*, Kalman is efficient, however we're dealing with a
managed runtime and limited hardware. even if we get a Kalman filter
running, it's hard to say now that it would perform well enough
without moving to the Android NDK (native development kit)
2) Kalman assumes noise is normally distributed (like a bell curve),
however I've seen evidence that the noise is biased somehow. you even
noted that motion seemed to change the noise characteristics of the
sensor, tho i didn't see the same thing. but i *have* seen that
playing any audio will *definitely* change the noise characteristics
of the sensor (although technically it's not inherent noise, it's the
sensor reacting the EM field of the speaker's driver).
3) Kalman is efficient because it is "hard-coded" with a sense of what
you expect your data to look like. So say you always want to track a
circular motion: you'd tell your Kalman filter "i'm expecting
something vaguely circular, now do your stuff and de-emphasize the
data that makes this look like something that's not a circle (the
noise)". So in your case, if I can assume you want to track arbitrary
motion, i'm not sure Kalman is useful. However, one possibility: if
you restricted your application to a handful of basic gestures you
could have a two-stage filter in which 1st you determine if the
gesture is even close to something you handle, then apply an
appropriate Kalman filter to it to remove noise. Then, this handful of
basic gestures could be composited together to allow more
sophisticated gestures like: arc -> sharp angel -> inward sprial, etc
4) Unless you're experienced with the math used in Kalman, you could
spend a few weeks getting it right ... it's not the simplest thing in
the world i'm afraid :)

anyway, i feel your pain. at the moment i have a decent app built up
for analyzing the characteristics of the acceleromater ... if you're
interested let me know and we mite post it to the market sometime
soon.

hth, chris

[android-developers] Re: Signing APK and "Conversion to Dalvik format failed with error 1"

[Ian]

thanks for the response...

I did a full clean reinstall of Eclipse Galileo + ADT 0.9.1 + SDK
1.5_r2

I created a new project called "Test" with no user code and referenced
Google Maps api.

I compiled and got this:

[2009-07-10 18:56:39 - Test] no classfiles specified
[2009-07-10 18:56:39 - Test] Conversion to Dalvik format failed with
error 1

If I try "export unsigned apk" it says "no Test.apk" so cannot export.

Then, I "refreshed" and built again with no errors.

[2009-07-10 19:06:09 - Test] Using default debug key to sign package
[2009-07-10 19:06:09 - Test] Packaging classes.dex
[2009-07-10 19:06:09 - Test] Build Success!

Now, export works, but the apk was signed with debug key and I think
you cannot resign with private key... am I wrong?

Checking the news boards, it seems this problem was never fixed but
people worked around by "refreshing" then rebuilding, but I don't see
how they could make a public release with this issue.  Am I to assume
everyone used ant manually to release onto the market?  Looking at the
Google I/O videos, it seems internally they only use Ant and nobody is
keeping Eclipse plugin up to date.

The export wizard works if there is an apk file... it doesn't care if
it's already signed with the debug key... maybe this doesn't matter?

[android-developers] BlurMaskFilter

[Sharmila]

Does the BlurMaskFilter works?I am trying to blur a greyscale image
captured by the camera using BlurMaskFilter...
Bitmap bm=Bitmap.createBitmap(bm.getWidth(),bm.getHeight
(),Bitmap.Config.ARGB_);
Canvas c=new Canvas(bm);
Paint p=new Paint();
p.setMaskFilter(new BlurMaskFilter
(radius,BlurMaskFilter.Blur.NORMAL));
p.setFilterBitmap(true);
c.drawBitmap(bm,0,0,p);
the image does not appear to be blurred?
Do I need to design my own filter for blurring?
Thanks,

[android-developers] Re: Using Intent to view specific App in Android Market

[iPaul Pro]

To do this in a future-proof way, you would set the  on
the receiver app to handle your type of data and sending extras with
the intent from the sending app.

For example: if you are making an app that SEND's plain text:

In the java of the app to send the text:

final Intent sendIntent = new Intent();
sendIntent.setAction(Intent.ACTION_SEND);
sendIntent.setType("text/plain");
sendIntent.putExtra(Intent.EXTRA_SUBJECT, EXTRA_SUBJECT);
sendIntent.putExtra(Intent.EXTRA_TEXT, EXTRA_TEXT);
   try {
startActivity(Intent.createChooser(sendIntent, "Send"));
   } catch (
android.content.ActivityNotFoundException ex) {}


In the manifest, in the appropriate activity:








In the java file's onCreate() check for the standard SEND EXTRAS:

final String EXTRA_SUBJECT = getIntent().getStringExtra
(Intent.EXTRA_SUBJECT);
final String EXTRA_TEXT = getIntent().getStringExtra
(Intent.EXTRA_TEXT);


This concept can be used for other data and intents as well.

Hopes this helps,

[android-developers] Re: EMMA Code coverage and JUnit

[Haritha]

Brett
first of all thanks for all the information on Emma coverage.
I have written my own instrument testcase for Setting  app and added
these to /packages/apps/Settings/tests/
with export EMMA_INSTRUEMNT=true;and mmm packages/apps/Setting
coverage.em,Settings.apk,SettingsTests.apk are generated.
But when i do adb shell am instrument -w -e coverage true
com.android.settings.tests/android.test.InstruementationTestRunner
 all the tests are performed on emulator but its giving error Error:
Failed to generate emma coverage.

i was able to generate reports for all apps that come with build
(apidemos,Calculator etc).
Is it possible to generate coverage through the tests that wont come
with android.If so what am i missing?
Are there any suggested solutions?
Any help is really appreciated.
thanks and regards
haritha

That's because the MediaPlayer doesn't know that you hit the back button.
Since you already have a SurfaceHolder callback, it's probably easiest
to stop the MediaPlayer in the surfaceDestroyed callback.

Yes, though you might be able to make use of MediaController to
minimize the work you have to do.

> 3. video is stretched out

You will have to adjust the size of the SurfaceView.

Also note that as of Cupcake, playing media from a resource using the
"android.resource://" Uri specifier should work. I haven't tried this
with VideoView, but you could give it a try. If it works, you get all
these things automatically.

[android-developers] FrameLayout and margins

[Ventrix Kostis P.]

I have the following piece of code but the margins are not set.

main.xml:

http://schemas.android.com/apk/res/
android"
android:orientation="vertical" android:layout_width="fill_parent"
android:layout_height="fill_parent">





setContentView(R.layout.main);
ImageView image1 = new ImageView(this);
image1.setImageResource(R.drawable.alien_256);
FrameLayout frl = (FrameLayout) this.findViewById(R.id.MainLayout01);
FrameLayout.LayoutParams params = new FrameLayout.LayoutParams(
FrameLayout.LayoutParams.WRAP_CONTENT,
FrameLayout.LayoutParams.WRAP_CONTENT);
params.leftMargin=50;
params.topMargin=40;
frl.addView(image1, params);

I have also tried using the params.setMargins(50, 40, 0, 0) but it
does not work either.

Any suggestion? (Absolute layout works just fine, too bad it was
deprecated)

I apologize for my mistake -- I was thinking of a different dex error.

That being said, recompiling the code in question is the only way that I
know of to perhaps get past this problem. However, in this case, you may
be able to just rebuild the third-party JAR using your version of the
Java compiler, rather than have to integrate its sources into your own
project.

That message is only ever produced because of entirely local
information about a class, and the trigger condition is exactly as
stated: A .class file apparently represents (what in the Java
programming language source was written as) an anonymous inner class;
per spec such classes are supposed to have both InnerClasses and
EnclosingMethod attributes, but dx observed it to have the former but
not the latter. Look here for further details:
,
starting around line 258.

The jar may reference classes that aren't included in the system as
well, but that wouldn't trigger the message in question. Dx isn't a
(cross-dex) linker, and so it never tries to resolve external
references in the first place (nor does it take arguments that could
possibly enable it to do so).

At least in some cases, that means you imported a precompiled JAR that
is not fully compatible, possibly due to references to missing platform
classes.

If you can, get the source code for that project and include the source,
rather than the JAR, in your project, and then fix whatever compiler
errors you wind up with.

First of all, this is a warning and not an error. The resulting file
should run just fine, except that if you attempt to use reflection on
the inner classes in question, the answers you get back will not be
correct. (This is because the compiler that produced the files was
broken and didn't provide consistent information.)

Yes, you probably can. Recompile the source for "felix.jar" with a
modern compiler, and the problem should disappear.

[android-developers] Can adb shell trigger onLowMemory

Does the adb shell or another development utility support sending or

I would like to trigger it to make sure my implementation frees
memory.  I find the idea of actually making the device or emulator run
out of memory is a bit unrealistic.

Try setting a SurfaceHolder callback and delaying the call to

callback.

[android-developers] Re: Can only hear sound when playing video

[Alslayer]

I noticed with all the copying and deleting code I forgot to add
setContentView(R.layout.main);.  So now I don't get the "The

up with a black screen then goes back the home screen.  Here is the
whole code and the xml.

import java.io.IOException;
import android.app.Activity;
import android.media.MediaPlayer;
import android.os.Bundle;
import android.view.SurfaceView;

public class myapp extends Activity {

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);

AssetFileDescriptor afd = getResources().openRawResourceFd
(R.raw.samplevideo);
MediaPlayer mp = new MediaPlayer();
SurfaceView sv = (SurfaceView)findViewById
(R.id.SurfaceView01);
mp.setDisplay(sv.getHolder());
try {
mp.setDataSource(afd.getFileDescriptor(), 
afd.getStartOffset(),
afd.getLength());
mp.prepare();

[android-developers] Re: Signing APK and "Conversion to Dalvik format failed with error 1"

[Roman]

Based on your description I assume that you can build successfully the
APK which is located in the bin folder of your project (of course it's
signed with the developer key).

Normally when you select the option "Android Tools->export unsigned
application package" a window pops up where you specify the location
of your new unsigned application. If this step does not work with your
application, did you try the steps with other applications to find out
whether it is related to your project or Eclipse setup?

You could also try to use the export Wizard to use your own keystore
to sign your application with your own key. The export wizard can be
found in the overview tab of your Manifest file. In this view you can
select exporting an unsigned APK or use your own created signature. Of
course to load an unsigned APK on a device you would have to go
through the signing process with your own created key.

Try examining the desktop version of whichever font you are using in a
font editor or "character map" sort of tool. You can download the
TrueType fonts for Droid Sans, Droid Serif, and Droid Sans Mono from
various places online, depending on your development platform.

Assuming the fonts in the firmware match the TrueType fonts, you will be
able to tell that way which glyphs are supported.

[android-developers] Re: android + pidgin = ???

[Yusuf T. Mobile]

Pidgin is a graphical front-end for libpurple using GTK+. (Thank you,
Wikipedia). So if you want Pidgin on Android, you could put an Android
UI on top of libpurple. libpurple is written in C, so you can use the
NDK for that part. An easier option would be to use a multiprotocol
library written in Java (e.g a Java alternative to libpurple), except
that I don't know of any.

[android-developers] Re: Packaging SQLite DB for deployment

I placed a file with my data in the assets directory.  You can then
access the file like this:

context.getResources().getAssets().open("session.txt")

and import your data.  I also run this import process in a separate

You are correct that you should use contentResolver.openInputStream

Default Email app, is very dumb and is hardcoded to only open audio
and image attachments.
(disclaimer, that was the case 6 month ago, the last time i looked at
it).

[android-developers] Re: Making a persistant content observer

[Streets Of Boston]

I'm not sure at all if this would work,
but have you tried to put the content-observer code inside a *service*
(instead of in your activity).

Start the service and keep it around.
And if the content changes, create a notification.
The notification can be noticed by the user and allows him/her to
start your activity.

[android-developers] About localization: 'NOT_FOUND' kind of strings

[Claudia]

Hello,

I'm localizing an Android phone and I was given several thousand
strings (mostly xml) of many kinds (apps, framework, GUI, content,
graphics, manuals, etc).

Some of those strings are what I assume keys for the Apps message,
like: NOT_FOUND or UNKNOWN_ERROR in the strings of each app. I've
never had to translate those in Win Mo apps, but this is my first
Android phone, so I want to be sure. So should I just leave those
strings as they are?

Thanks.

[android-developers] Re: conversion to dalvik format failed with error 1

[Ian]

please someone help with this...

i'm getting the same issue and I think it's preventing me from
releasing my APK. It looks like I cannot build the apk w/o Eclipse
using the debug key to sign it, but I need an unsigned apk.

I've used the wizard, that's not the issue.  The wizard just takes the
already signed apk (debug) and creates/"exports" another file but that
file seems messed up bcos when I run later with maps api the emulator
cannot access maps.

This all works when I actually want the debug-signed apk.  Yes, I
changed my map key references before compiling.

this is what i'd like to do:

1) get release key and maps key
2) compile unsigned apk
3) sign it
4) run it

unfortunately this "conversion issue" prevents unsigned apk,
instead, this happens:

1) got keys
2) compile fails
3) refresh then build again -> now compiles -> created debug SIGNED
apk -- bad
4) signed again with private -- seemed ok, but not?
5) emulate fails maps api access -> this worked when using debug key

i'm using gaymede eclipse with Android plugin 0.9.
I tried full reinstall of everything.

please help

below is jarsigner verification of doubly signed apk.

[android-developers] Speech Recognition application

[campi]

Hi,
such as the name of the topic says, I am developping an application
based on speech recognition. I intend to develop the recognition part.
Since it requires quite a lot of operations, I was wondering wether an
Android Phone, such as the Dev Phone 1, could handle it. So could I
develop such an application directly on the phone, or should I use a
server to take care of the recognition ?

Hi,

I'm working through your gps example but I get a "sorry, app has

include the ACCESS_FINE_LOCATION permission line in the manifest.xml
file.)

Thanks,

   // LocationManager gets GPS location

[android-developers] General UI Questions

[bnovc]

I just started trying to learn the Android SDK, and I've noticed that
it seems to lack a lot of documentation.

I was trying as a first exercise to add an "Every Day" option to the
alarm clock that would click the other items when it is checked. In
onPrepareDialogBuilder, I can check which index was clicked on, but I
don't know how to set the items to checked.

It seemed like I needed to use DialogPreference instead of
ListPreference in AlarmClock's RepeatPreference.java, but I don't
think I understand the relationship between DialogPreference,
ListPreference, and AlertDialog though.

If I change to a DialogPreference, I can add a LinearLayout in the
onCreate method, but it didn't make sense how I would add
CheckBoxPreferences to it. There's also a ToggleButton. Should I be
trying to add that instead? I can't find any examples of
DialogPreference being extended except in the Android code.

Thanks for any information

[luoqii]

Hi, every one , i want to know is there any one who are interest in
porting integrating IM Pidgin to Android. As i know, in android
market, there are several IM client, such as meebo,palringo, which are
fine to us, but for me who reside in china, it's not enough, these IM
client support QQ, fetion, and so on, and it's believed that these IM
client are not open-source, so i want to do a porting working in
Android.

so , any advises are expected.

[android-developers] Re: Low accuracy of the accelerometer Sensor

[keyboardr]

I'm not 100% familiar with this aspect of the G1, but I know Nintendo
had a similar problem with their Wiimotes.  That's why they have the
sensor bar set up: they couldn't get their accelerometers to be
accurate enough to track position.

[android-developers] Indication of user activity from a service

[dadical]

I need to determine if a user has interacted with the screen,
keyboard, or trackball from a background service.  I don't need to
know coordinates, or actual keystrokes.  I just need to understand if
they have interacted with the phone in any way.  Anyone have any
creative ways to do this?

It would be great if the screen/keyboard/keys/trackball were available
in a manner similar to the other Sensors available on the phone, but
it seems that access to input devices is restricted in services as
part of Android security policies.

Based on my research, I'm not finding much of a possibility, so here's
what I'm considering:

- using information related to the current processes/activities via
ActivityManager to guess if an activity is being interacted with.
Possibly the amount of CPU time would increase more rapidly if the
user is typing or touching the screen?  Seems fairly unreliable...
- using one of the sensors to attempt to determine interaction with
the phone.  Acceleromter fluctuations, magnetic field fluctuations,
tricorder :).
- something else?

Thanks for any creative suggestions.

[android-developers] Re: Home Screen Sample

[camandroid]

Apparently bindFavorites() aims only to retrieve the favorite
application.
Since we don't have this file /system/etc/favorites.xml, we are not
obliged to manage it.

What I did is:
- initialize mFavorites at the top and
- fill it from favReader only if favReader != null.

of course at the step: mApplicationsStack.setFavorites(mFavorites);
  mFavorites is an empty list.
But this will prevent the crash in
ApplicationsStackLayout.stackApplications(List
applications, int childLeft, int childTop)
applications (comes from mFavorites) is then not null.

private void bindFavorites(boolean isLaunching) {
 if (!isLaunching || mFavorites == null) {

 if (mFavorites == null) {
 mFavorites = new LinkedList();
 } else {
 mFavorites.clear();
 }

 FileReader favReader = null;
 // Environment.getRootDirectory() is a fancy way of saying
ANDROID_ROOT or "/system".
final File favFile = new File(Environment.getRootDirectory
(), DEFAULT_FAVORITES_PATH);
try {
favReader = new FileReader(favFile);
} catch (FileNotFoundException e) {
Log.e(LOG_TAG, "Couldn't find or open favorites file "
+ favFile);
}

if (favReader != null) {
final Intent intent = new Intent(Intent.ACTION_MAIN,
null);
final PackageManager packageManager =
getPackageManager();

try {
  ...
 } catch (XmlPullParserException e) {
Log.w(LOG_TAG, "Got exception parsing favorites.",
e);
} catch (IOException e) {
Log.w(LOG_TAG, "Got exception parsing favorites.",
e);
}
}
}

mApplicationsStack.setFavorites(mFavorites);

}


This works fine for me.

I'd like to simulate the  /system/etc/favorites.xml
Anyone knows it format ?

[android-developers] Signing APK and "Conversion to Dalvik format failed with error 1"

Help!

I've been trying to use Eclipse and the Export Wizard to create a

unfortunately, I cannot seem to generate an UNSIGNED apk.  Every time
I "clean and build" I get the error below, which I read I can get rid
of by "reload" or refresh then building again.  however, the debugger
automatically signs with the debug key after I do this, defeating the
purpose.

[android-developers] Re: Signing APK and "Conversion to Dalvik format failed with error 1"

[Ian Gavalakis]

update:

when I try to "export unsigned" it fails because no APK was generated,
likely due to the error.  again, reloas/build-again creates an exportable ak
but it's signed with debug key... useless...

p.s. Romain, please forgive me for including you, but you seem to be one of
the best responders for Google on Android.  I spent a day on this issue w/o
success.

[android-developers] Error on SharedPreferences for AppWidget

[Stefano Sanna (gerdavax)]

Hi.

I'm working on an AppWidget which manages settings using
SharedPreferences. I'm experiencing a strange behaviour (on a Dream)
on its configuration Activity:

1)  if I use software keyboard (that is: without opening physical
keyboard) to edit text, everything works fine and preferences are
stored. The happens if the application starts with keyboard already
open.

2) if I open physical keyboard (and activity is being restarted and
rendered in landscape), when saving preferences the widget does not
appear on the desktop. Sometimes I get an error message ("unable to
unlink" to the path of application's data).

It seems that, when restarted on keyboard open, the configuration
Activity looses ownership of its sharedpreferences.

Any idea?

Thank you.

Ciao,
Stefano.

[android-developers] Re: Start TTS from broadcast receiver

[Dianne Hackborn]

*sigh*  That solution you were given is utterly broken -- the restriction
placed on the context is to HELP people from doing stuff that is not
actually going to work all of the time (since your hosting process can be
killed any time after onReceive() returns, before onBind() comes back).  So
this person is deliberately being tricky to work around the help the system
is providing to not do something broken, so they can do something broken.

AG.

Could you please tell this person to stop this?  And I'll probably modify
the platform in the future to also impose this restriction on the other
context, to keep people from making this mistake.  Hopefully it doesn't
break too many apps. :p

[android-developers] Re: Making a persistant content observer

[Dianne Hackborn]

Sorry, there is no support for this, besides ensuring you are always running
with a service...  and you should really really avoid that.  We deliberately
don't allow apps to be launched from content changes due to significant
concerns about how this can impact performance if a number of apps end up
getting launched each time there is a change in some content provider.

If I'm reading that correctly that means it is crashing on:
mp.setDisplay(sv.getHolder()) so either mp or sv is null.

[android-developers] How to get the video stream from MediaRecorder?

[manoj]

hi,

I want to get the stream and send it to server directly by using
MediaRecorder.

Actually, I am able to record the video,and able to store it into
sdcard. Now I want to it to stream (live stream) to server rather than
storing it.

Can any one please suggest me how to do it?

Thanks,
Manoj.

You cannot, that's the whole point. These are private APIs that will

NOT run on "all public android systems."

[android-developers] TabHost + ListView + SMS == bug?

[extrapedestrian]

I have TabHost with ListView as tab content. ListView has context menu
that opens send SMS activity.
After returning from SMS screen when I try to switch tab ListView
disappears and can not be displayed for second tab until application
is restarted.

I made simple example if someone can confirm this issue, please follow
steps at the bottom:

public class TabHostListView extends TabActivity implements
TabHost.TabContentFactory {
/** Called when the activity is first created. */

private String mListOfResults[] = {"item1", "item2", "item3"};

@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);

TabHost.TabSpec spec=getTabHost().newTabSpec("First");
spec.setContent(this);
spec.setIndicator("First");
getTabHost().addTab(spec);

spec=getTabHost().newTabSpec("Second");
spec.setContent(this);
spec.setIndicator("Second");
getTabHost().addTab(spec);
}

@Override
public View createTabContent(String arg0) {
// create list here
LayoutInflater inflater = LayoutInflater.from(getBaseContext
());
ListView mLV = (ListView)inflater.inflate
(R.layout.list_layout, null);
mLV.setAdapter(new ArrayAdapter
(this,android.R.layout.simple_list_item_1,mListOfResults));
registerForContextMenu(mLV);
return mLV;
}

@Override
public void onCreateContextMenu(ContextMenu menu, View v,
ContextMenuInfo menuInfo) {
// Display sms action
super.onCreateContextMenu(menu, v, menuInfo);
menu.setHeaderTitle("Actions menu");
menu.add(0, 0, 0, "SMS");
}

public boolean onContextItemSelected(MenuItem item) {
/* Send SMS */
try {
String phone = "123123";
startActivity(new Intent(Intent.ACTION_VIEW, Uri.fromParts
("sms", phone, null)));
} catch (ActivityNotFoundException e) {
Toast.makeText(getBaseContext(), R.string.failed,
Toast.LENGTH_SHORT).show();
Log.e("EdithActivity", "SMS Contact failed" );
}
return super.onContextItemSelected(item);
}

}

list_layout xml file:



http://schemas.android.com/apk/res/android";
android:id="@+id/listTabView"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
/>

Steps to reproduce the bug:

Start program  -> there are two tabs and a list.
Select list item with longpress -> Context menu appears.
Click SMS -> SMS app appears.
Type in few letters and press back -> Toast is displayed, and your are
back to test activity.
Try to switch to tab 2 -> there is no content in tab2! List is not
displayed!

Make sure you dont go to tab2 first, then it works ok!
Make sure you type few letters (at least one) in SMS window, if you
return immediately - it works ok too.

[android-developers] Re: A question regarding the MotionEvent

[nEx.Software]

The chances that your start and end location will be exactly the same
are slim to none. If you want to do it all in a regular old
onTouchEvent(), you'd want to have some sort or range... If down and
up occur within some small range such as within 10 or something like
that. Depending on what exactly you are trying to accomplish, you
might be better off implementing OnGestureListener.

If you are using the stock Ant build.xml, just put the JAR in your
project's libs/ directory, and it will be included in the compile and
the APK packaging.

I'm pretty sure there was more than just "NullPointerException" in the

[android-developers] Making a persistant content observer

[jrgraf...@googlemail.com]

Hey guys,

Quick question: I am trying to make a permanent contentObserver that
observes content://sms. The way I do it atm is have an initial
configure Activity with my application that calls the following code:

ContentResolver contentResolver = getContentResolver();
SMSHandler handler = new SMSHandler();
SMSObserver resolver = new SMSObserver(handler);
resolver.setApplication(this.getApplication());

contentResolver.registerContentObserver(Uri.parse("content://sms"),
true, resolver);

Now this all works fine...for a while; it seems that about 20 minutes
after exiting said activity the ContentObserver will get removed and I
will need to re-launch the Configure Activity to re-attach it.

Is there any way that I can make sure that this content observer can
permanently listen for changes without ever being killed?

Thanks in advance!

[android-developers] Using ANT not Eclipse, How do I add a 3rd party jar

[moa]

Hi,

I want to be able to add google's exteneded json library to my app
(gson.jar). I can get it in the path so I can compile but it is not
being bundled into the application when being deployed. How can I do
this?

I am NOT using eclipse, so need to do it via the ant. I'm actually
using Netbeans as my ide and all works sweet but for this.

[android-developers] Sliding the view when opening Virtual Keyboard

[Hazam]

Hi guys,
I was wondering if there is a method for controlling the amount of the
View that gets scrolled when opening the virtual keyboard.
Right know it scrolls just enough for letting the relate EditText show
itself (and not perfectly too, like it scrolls fully in just after the
first typed character), but i need to scroll a little more to show
another widget together.

In Iphone we have *scrollRectToVisible*, do we have something similar
in Android 1.5?
Thanks

[android-developers] Re: EditText and Virtual Keyboard

[Hazam]

Hi Hong,
thanks for your reply.
I tried that but to no avail.
The reason seems to be that clicks and actions from virtual keyboard
do not follow the same
path that normal key and touch events do.
The get tunneled in an InputConnection, and things get REALLY
difficult for me to understand fully.
So i just override onCreateInputConnection and return a
BaseInputConnection and now it works.
thanks again for the reply,

-Emanuele

[android-developers] Re: Packaging SQLite DB for deployment

Or, if you are working with the SQLiteOpenHelper base class, then you
could export your DB to a text file (including CREATE TABLE, INSERT,
etc.), place this in your "assets" folder and import the file in the
overridden "onCreate" method of SQLiteOpenHelper.

As we know, Google has hidden some APIs on newer SDKs, some of
providers(i.e. Telephony provider) are hidden, we can only seen in
source code, but we can not use on the current SDK. So I wonder how we
can use these providers. I know we integrate our own firmware,
however, I wonder if we can solver this problem on the current SDK, so
that my app can run on all public android system.

You could send it programatically but you would probably need to look

Start here -

good luck!

You need to grab GPS status messages, and are you after signal strength or

Try moving the  and
  lines closer to the top of the
file, so  is the first child of  and 
is the first child of . The Android XML parsing logic
sometimes is position-dependent, and I usually see these at the tops of
files, not the bottom.

More generally, see if you can get any existing, known-to-work mapping
examples running, then start to adjust your code to more closely match
what is in the example.

Also, is your AVD set for target 3 (-t 3)? If it is a target 2 AVD,
there is no mapping library.
