[android-developers] Re: Google Maps Broadcast Event for audible navigation instructions start and stop?

+1. I am interested in this functionality too, to mute my app when
Google Maps Navigation is talking.

[android-developers] Re: IllegalStateException: not connected to MediaScannerService?

[blindfold]

Today I received yet another instance of this crash problem, again on
a Droid with Android 2.01:

java.lang.IllegalStateException: not connected to MediaScannerService
at android.media.MediaScannerConnection.scanFile
(MediaScannerConnection.java:148) at
blah.blah.blah.onMediaScannerConnected(Unknown Source)

Is this a Droid bug, or am I missing something? My code is nothing
special, and is just meant to update the image Gallery after writing a
JPEG file. Must one add a supplementary MediaScannerService check, and
if so, how?

Thanks

Yes. You still need to do that. If applications do not call
setPreviewDisplay, camera drivers may not start the preview even if
startPreview is called. Ex: the current implementation on Droid.

[android-developers] Anybody know the number of Android user that can buy app against those who cant?

[RobGThai]

While Android seems to be raging recently, however not all users are
able to buy application through Market (Thanks Google and their
limited policy).

I just don't know why should I developing an app for a platform that
doesn't really convinced me that it will make me some profit. At the
very least, Google should be able to provide the number of users
logging in to the Market and download paid applications.

I have an unrooted phone sitting here and like 65% of the apps (if not
more) consists of some show-random-photos and sound-clips, I don't
even know if I should call them applications any more. So unless the
apps get some recommendation from somebody, it is more than likely
that it will not get hit unless user know what they are looking for.

The problem comes from the ability for developer to sell and buyer to
buy. It doesn't matter how many phone will be bought in the following
year or how many model will come out. If the user can't buy it, those
number are meaningless to developers.

The whole concern was actually from people asking why am I doing it
when I dont get paid. It's actually a very good question. Not to
mention couple of iPhone developers that suggest AppStore.

It's all based on some article on the net and people around me though.
Has anybody feeling that way as well?

[android-developers] Re: Disable spinner item?

[rexowner]

Thank you for your reply.

None of the 2 Class methods or 8 inherited methods on the page cited
appear to have
anything to do with disabling items in the list.  None of the
subclasses
appear to have a way to do this either.

Maybe I am dense, but it is not at all clear how to do this.

[android-developers] Re: GLSurfaceView.Renderer render rate

[Robert Green]

If you're using the render-continuously mode, she'll go as fast as she
can go.  60FPS if you're doing easy HW-accel 2D or very basic 3D.
I've never seen over 60FPS.  It's probably vsynced to that.

I like to use a shared object called the World to pass between my
logic thread and renderer thread.  Logic updates world, renderers
draws it.  Simple!

I keep a simple boolean isLocked on the World and synchronize the
calls to getLock() and release().  You will want to set a max rate for
your logic thread to run and have it figure out how many MS to sleep
for.  I didn't do that the first time and mine would run at 200-300fps
while rendering at 30-60.  That was a big waste of CPU cycles :)  None
of my code does that anymore.

[android-developers] Re: Copy protection bug statuses

[rflexor]

I'd like to switch off copy protection for my app, too.

I think I have successfully managed to reproduce this issue on an 1.5
emulator _just_once_. What I saw from the logcat was that the process
couldn't access the preferences and the database because it ran under
a different UID than the UID that database was stored with. Is this
the error you are referring to?

I'd like to provide a wrapper that tests this condition and guides the
customer to an uninstall. But I'd have to reproduce this condition to
safely test against it. Any ideas how to get this reproduced
successfully on an emulator?

I tried a lot of combinations of

adb -e install -l 


adb -e install -r 

But nothing yet ...

[android-developers] Re: frame buffer data in android

[Niraj]

Hi,

I am collecting framebuffer data directly from /dev/graphics/fb0.
This way works properly while working with android emulator.

I am using C code for this purpose, as I didn't get any functionality
in java to read framebuffer directly.
And I am using JNI to call this C function in Android.

If you need the C code for reading framebuffer data, I can directly
mail you.

[android-developers] Audio options for music app - should I use JET?

[k_day]

I am currently working on a music app and am starting to think about
how audio playback should work.  At any given point in time, a user is
able to play multiple notes from multiple instruments.

My initial thought was to use JET, but I am thinking it may be too
limited given that I also would like to:

[android-developers] Re: GK:How to Kill all Activity at a time ?

[Jack Ganesh]

Hi..,
 i used the following :

void onClick(){
android.os.Process.killProcess(android.os.Process.myPid())

System.exit(0);

}

but still its coming back to the previous activity.

Any other try ? ?


Cheers,
Ganesh


>>

Hi Ganesh,there are two ways

android.os.Process.killProcess(android.os.Process.myPid())

System.exit(0);

I normally use the second, I agree that some times you just want to
properly exit an app as you dont want it using memory and slowing
your  phone

[android-developers] Re: GLSurfaceView.Renderer render rate

[Jeremiah Sellars]

I suppose I should add... that my background is homebrew for Nintendo
DS and coding in C. The game loop would generally just include a call
to wait for the screen's vertical blank and that was ~1/60th of a
second. It couldn't be relied upon totally for timing, but as long as
you weren't running really intense operations it was fine. DS Homebrew
is substantially closer to the hardware and the combination of
learning Java, OOP concepts, working with a very large API and
applying everything to a new platform is causing me to ask some likely
stupid questions.

Anyway, I hope someone can find a moment to help.

Thanks again,
Jeremiah

[android-developers] Import existing project into workspace - Can't see Android Library in Java Build Path

[Miguel Paraz]

Hi,
In Eclipse, when I "Import an existing into workspace" (from a
Mercurial repository, if it matters), I don't have the "Android
Library" in the Java Build Path. Instead, I get "Unable to get system
library for the project."

The .classpath file does have:



and the other projects in the same workspace are OK.

I tried a combination of: refresh, clean/build, fix project
properties...

Looks like this setup is fragile.

In looking through other message boards it appears this might be

Re: [android-developers] checkbox and icons in listview

[Jose Gomez]

Hey I just wrote something like this I couldn't find any examples either but
I can give you some pointers.

Declare your List View Layout


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





Declare another layout file for the specific rows.in my cae I have a checkbx
and two textvies but it should be obvious how to change it just add or
remove fields.

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



Then if you are trying to  get the information out of a custom class say in
my case the shopping list class you need to create a custom Array Adapter
that will utilize this layout
at the bottom you see where I assign the different fields like the 2
textviews and the checkbox to a particular field in the class.

package unf.edu.esifall09.team1;
import java.util.List;

import unf.edu.esifall09.team1.R;
import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.CheckBox;
import android.widget.LinearLayout;
import android.widget.TextView;


public class ShoppingListAdapter extends ArrayAdapter {

int resource;
public ShoppingListAdapter(Context context, int resource,
List items)
 {
super(context, resource,items);
this.resource=resource;
 }
 @Override
 public View getView(int position, View convertView, ViewGroup parent)
{
LinearLayout shoppingListItemView;
 ShoppingListItems sli =getItem(position);
 String prodName =sli.getItemDescription();
double price = sli.getPrice();
 boolean purchases = sli.isPurchased();
 if(convertView==null)
 {
shoppingListItemView = new LinearLayout(getContext());
String inflater = Context.LAYOUT_INFLATER_SERVICE;
 LayoutInflater vi;
vi = (LayoutInflater)getContext().getSystemService(inflater);
 vi.inflate(resource, shoppingListItemView, true);
}
else
 {
shoppingListItemView = (LinearLayout) convertView;
}
 CheckBox chkPurchased =
(CheckBox)shoppingListItemView.findViewById(R.id.rowItemBought);
 TextView itemName
=(TextView)shoppingListItemView.findViewById(R.id.rowItemName);
TextView itemPrice
=(TextView)shoppingListItemView.findViewById(R.id.rowItemPrice);
 chkPurchased.setChecked(purchases);
itemName.setText(prodName);
itemPrice.setText(Double.toString(price));
 return shoppingListItemView;
 }

}


Ofter that is created go to the activity where you will like your ListView


Declare your Variables
ArrayList items;
ShoppingListAdapter adapter;
ListView lv;

Then on create set up your list view and your adapters

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

lv=(ListView)findViewById(R.id.lvItems);
items= new ArrayList();


do a loop of some sort to fill in your adapter. Like in my case I read form
a Database

Cursor itemsCur=productsDb.getAllShoppingListItemsCursor(shoppingListPK);
 do{
ShoppingListItems sli = new ShoppingListItems();
sli.setItemDescription(itemsCur.getString(2));
 sli.setPrice(itemsCur.getDouble(4));
sli.setPurchased((itemsCur.getInt(7))==0?false:true);
 sli.setQuantity(itemsCur.getDouble(5));
sli.setShoppingListItemPK(itemsCur.getInt(0));
 sli.setShoppingListPK(itemsCur.getInt(1));
sli.setStorePK(itemsCur.getInt(6));
 sli.setUpc(itemsCur.getString(3));
items.add(sli);
}while(itemsCur.moveToNext());


Set the data into your adapter and add to the List View
adapter= new ShoppingListAdapter(this, R.layout.shippinglistitem, items);
lv.setAdapter(adapter);


}


That should do it Hopefully it makes sense!

Jose C Gomez

[android-developers] How can I receive WAP Push with custom MIME Type?

[RainBow]

Hello,

I am trying to write a simple code that will receive a WAP Push
message on my device. However, when I send a wap message with a custom
mime-type, I get the following error (taken from logcat logs):

Received PDU. Unknown Content-Type = XYZ

where XYZ = my custom MIME-typed message

Looking at the relevant telephony code (WapPushOverSms.java), I found
that their is no switch in the code that will be able to handle a
custom MIME type. (Please see the code below)

So, how do I go about sending a wap-push with custom MIME type? Any
inputs/ideas?

Thanks for reading/answering my post in advance.

Kind regards.

Relevant code from WapPushOverSms.java:

 if (mimeType.equals
(WspTypeDecoder.CONTENT_MIME_TYPE_B_DRM_RIGHTS_XML)) {

 129 binaryContentType =
WspTypeDecoder.CONTENT_TYPE_B_DRM_RIGHTS_XML;

 130 } else if (mimeType.equals

WspTypeDecoder.CONTENT_TYPE_B_DRM_RIGHTS_WBXML;

 132 } else if (mimeType.equals
(WspTypeDecoder.CONTENT_MIME_TYPE_B_PUSH_SI)) {

 133 binaryContentType =
WspTypeDecoder.CONTENT_TYPE_B_PUSH_SI;

 134 } else if (mimeType.equals
(WspTypeDecoder.CONTENT_MIME_TYPE_B_PUSH_SL)) {

 135 binaryContentType =

 137 binaryContentType =

 138 } else if (mimeType.equals
(WspTypeDecoder.CONTENT_MIME_TYPE_B_MMS)) {

WspTypeDecoder.CONTENT_TYPE_B_MMS;

 140 } else {

 141 if (Config.LOGD) Log.w(LOG_TAG, "Received PDU.
Unknown Content-Type = " + mimeType);

 142 return;

[android-developers] checkbox and icons in listview

[Abhi]

Hi,

I am looking to create a custom ListView with 6 fixed items in the
list. Each list row comprising of the checkbox, image icon and a
single line of text. I have read couple of tutorials but none of them
seem to be that well explanatory. Could someone please guide me to a
sample code? That would be great help.

Thanks,

Abhishek

That's because you don't.

http://github.com/commonsguy/cw-advandroid/tree/master/Sensor/Compass/

Or, to quote from the docs:

"Sensor.TYPE_ORIENTATION:

All values are angles in degrees.

values[0]: Azimuth, angle between the magnetic north direction and the Y
axis, around the Z axis (0 to 359). 0=North, 90=East, 180=South, 270=West"

http://developer.android.com/reference/android/hardware/SensorEvent.html

What you are trying to do is not use the compass
(Sensor.TYPE_ORIENTATION), but rather the raw magnetic field
(Sensor.TYPE_MAGNETIC_FIELD). *That* might need trigonometry to achieve
what you need, but I suspect the vast majority of things that need the
compass can just use the degrees supplied by the compass.

[android-developers] Re: Getting magnetic field results as degrees

[Jeffrey]

I got it working, the phone will only need to be lying flat, so that
made it a lot easier. It seems like google should mention somewhere
that you need to use trig to get degree's from the compass... That
doesn't quite seem like general knowledge. Though I had a problem with
the activity force closing occasionally but I fixed that so that it
wouldn't try and take sensor readings until the activity had been open
for 1 second. It also adds to the suspense of what direction the drift
will be :)

[android-developers] GLSurfaceView.Renderer render rate

[Jeremiah Sellars]

Hello everyone,

Continuing to tackle a game project, I've learned tons and have tons
more to learn.

>From what I've picked up, a "proper" game would have at least 3
threads. The main activity thread which would likely double as the UI
thread, the GL Renderer thread which is setup automatically with the
GLSurfaceView.Renderer and then a Game Logic thread. As I understand
it, I'll need to make sure to setup a sleep timing in the game logic
thread to have it behave correctly, but what I'm not sure on is at
what timing is the Renderer thread working at? Exactly how often is
onDrawFrame() being called?

Thanks everyone!
Jeremiah

In onCreate() of your SQLiteOpenHelper, you can call execSQL() as many
times as you like, to execute as many SQL statements as you like. You
can have as many tables, indices, triggers, and whatnot as SQLite
allows, certainly greater than one of each.

So, call execSQL() once to create one table and once to create another
table. Or, courtesy of that semicolon, you may be able to put both
CREATE TABLE statements in a single string -- I haven't tried that.

[android-developers] Creating databases

[Neilz]

I've made a few apps now, which use an SQLite database, no problems.
In my latest app, I want two tables, and I just realised that every
example I can find only creates one table.

So, is this a limitation? Must I use only one table? Assuming I can
use two, how do I go about changing my create script? Here's a normal
one, as per the examples:

private static final String DATABASE_CREATE =
"create table myTable (_id integer primary key autoincrement,
"
+ "description text not null); " ;

If there's an example elsewhere, I'd be grateful for a link... thanks.

[android-developers] Androi ASE

[intbt]

ASE will not install on my G1, I assume it is because I am running 1.5
and it requires 2.0.

I can get ASE to run on the Eclipse emulator when it is running 2.0
(not 1.5 or 1.6).

Is this correct and where is this described as a requirement for ASE?

(As an aside, the G1 downloads for 1.6 at HTC/developers are not
working - not sure what the problem there is...)

[android-developers] Re: [Android 2.0] Contacts FAQ?

[Mo]

Hi Rachel,
This is a very informative and helpful blag. I really helped me in
with questions I had about 2.0 API changes for Contacts.

One thing I am still not able to resolve is "How to get all the email
address for a contact" As you mentioned in your explaination that
"ContactsContract.CommonDataKinds.CommonColumns class does not exist."
so how did you made it to work?

Thanks,
Mo.

[android-developers] Re: JDBC Driver for SQLiteDatabase

[jotobjects]

JDBC drivers are never used directly by JDBC applications. In a JDBC
application you reference the URI name of the driver in
DriverManager.getConnection().  That is the only time you ever see the
driver and you never actually call a method on the driver itself in a
JDBC application.  This has nothing to do with Android. It is just
part of JDBC.

[android-developers] Re: How to add a third-party jar into apk?

[jotobjects]

The problem here is that javax.xml.transform is not part of the
Android platform so you will not be able to use this jar file with
your Android app.

All you have to do to use a third-party jar with Android is to drop
the jar file into your project lib directory. However if the jar has
dependencies then the classes in the jar may not work.

[android-developers] Re: Hardware/Carrier Compatibility Group

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

Probably too early for you yet but I solved this problem by recruiting
a beta test team from my users. On the last page of help text, I asked
for beta testers and about 30 (a couple new every day) responded so
far with a desire to assist in testing the app. They have a variety of
devices and OS's so I get a pretty good range of test conditions, plus
users will do the darnedest things, stuff I'd never think of.

Once you get your app released to the market, you might try and build
your own test community as well.

[android-developers] Hardware/Carrier Compatibility Group

[polyclefsoftware]

I don't know about most of you, but as an indie developer I'm faced
with the growing need to:

1) Test visibility of my app on various hardware/carrier combinations
2) Test basic functionality on various hardware/carrier configurations

You would think it would be a wise investment for manufacturers to
gift phones to devs for testing purposes, but most don't. It would be
nice to have a collection of devs and/or users who have access to as
wide a range as possible of configurations, so a dev with a new app
could just send a mail to everyone on the list and ask them to check
that the app is available on the market from their device and that it
downloads and seems to launch and run all right.

Is anyone else interested in trying to form such a group? Does anyone
have any suggestions on the best way to organize it (website, separate
mailing list)? I wouldn't want to clog this list every time someone
wants to check an app.

Thanks,
Derek

[android-developers] PCM Data - Frame Count

[Business Talk]

I am using the length of my PCM data buffer to calculate the number of
frames; depending if its mono or stereo or 8bit or 16bit.

For example, if it is a mono/8bit then the number of frames is the
length of the buffer. if it is stereo/16bit the number of frames is
the length / 4.

The problem is that the buffer, I create by reading the PCM raw
resource (file), seems to be too long (look below) . Therefore the
number of frames is also too heigh. why am I getting the buffer longer
then it should be?

there is another way to calculate the number of frames;



Number of Frames =  * 

for example 11.025[kHz] * 4000 [ms] = 44100 [frames]

the above calculations should yield the same result, yet they don’t
(the problem is with the buffer length). I am certain that the second
result is correct. am I doing something wrong with the way I read in
the data? I should put it into the WHILE loop when reading. But that’s
not it.



Here is how I create the buffer;



private byte[] readResource (int resourceId)
{
InputStream inputStream = null;
byte[]  inputBuffer = null;
try
{
inputStream = _Context.getResources().openRawResource
(resourceId);
inputBuffer = new byte [inputStream.available()];
inputStream.read(inputBuffer);
}
catch (IOException e)
{
Log.e(this.getClass().getName(), String.format("readResource:
Exception: %s", e.getMessage()));
}
finally
{
try
{
inputStream.close();
}
catch (IOException e)
{
Log.e(this.getClass().getName(), String.format
("readResource: Exception: %s", e.getMessage()));
}
}
return inputBuffer;
}

[android-developers] ExpandableListView change background for child items

[droidin.net]

I'm using ExpandableListView in my app and one of the complains is
that when expanded it's hard to visually distinguish where the child
item ends and next group item begins. So I would like to change
background of the child list item to the different shade. Brutal
attempts that I've made so far were based on directly changing
background color and text of the elements inside the child view item
but that leads to loss of hovers and highlights. So my question is -
what is a good strategy to achieve the above? I tried styles and
selectors but what really bums me out - that if I change one thing
then I need to add selectors for all combinations of focus/enabled
etc. when all I'm trying to do it to overwrite a single thing. Is
there a way to inherit parent style and set just a background for non-
focused, enabled child item?

[android-developers] TTS over bluetooth

[Declan Shanaghy]

Using Android 2.0 SDK.
Is it possible to direct the TTS engine's output to a connected BT headset?


I've tried with KEY_PARAM_STREAM set to all of the available stream types
but the speech is still output by the speaker on the phone.

Any guidance or suggestions welcome.

[android-developers] TextView ems, sp, typeface attributes

[jotobjects]

I'm using android:ems or android:minEms to fix the minimum width of a
set of buttons so they are all the same width.  Are there better ways
to accomplish that objective?  This works but there are some mysteries
regarding ems.

The ems attribute works correctly with the normal typeface, but
typeface "monospace" is quite a bit smaller/tighter and the ems
attribute does not scale to fit the width of characters in monospace.
For instance, if minEMS is set to 8 it has has room for 12
characters.  Without monospace it fits exactly 8 'm's.  Just wondering
if this is correct behavior and how to know what ems means with
monospace.

Also I'm not clear on the difference between 'sp' and 'dp' for
textSize measure.  TextView docs recommend using 'sp' but I haven't
found where the user scaling factor can be changed.

Hi,

I'm trying to create a file on the sd card. Using this:

  OutputStream out = new FileOutputStream("/sdcard/tmp.jpg");

but that throws a FileNotFoundException. Isn't OutputStream supposed

This is on a 1.6 emulator. I have an SD card installed, I'm looking at

[android-developers] Difference between pressing 'Back' button and 'Menu button

[hap 497]

Hi,

I have an activity on Android with a content view.
After I launch my activity, and I launch another activity on top of
it. And when click 'Back' Button, my activity looks fine (all the text
view and text view values are there).

But when I launch my activity, leave the phone idle and have the blank
screen shown, and press 'menu' button to unlock the screen, some of my
text view's values are not there.

Can you please tell me what are the difference between these 2 cases?
I assume onPause()/onResume() will get called the same way. But why i
don't see some of the text view text values?

Thank you for any advice/suggestion.

[android-developers] Google Maps Broadcast Event for audible navigation instructions start and stop?

[skyhigh]

I have an application which is playing audio.  I have some customers
that use this application while driving and who also use the Google
Maps application to get directions to the places where they are
driving.

They have asked me to change my application to pause my audio while
the Google Maps application is giving them audio navigation
instructions.  I am trying to find out if I can register a Broadcast
Receiver to let me know when the Google Maps application is giving
audio navigation instructions, or if there is a way to detect when any
other application has started or stopped playing audio.

It seems that this type of functionality would be beneficial for
Google Maps and for any type of application which is playing media, so
I am hoping that Google Maps is broadcasting events when it starts and
stops giving audio navigation instructions, or that there is a generic
way to discover when overlapping audio sources are trying to play.

[android-developers] In Android 2.0.1 on Droid, the accelerometer seems to stop working when you turn off screen?

[Artem - WorkSmart Labs]

Has anyone else seen this? I just wanted to confirm before filing a
report.

This used to be (what I thought was) a hardware problem with the G1 at
some point, but I thought it was resolved for the Droid.

Does anyone have any insights?

[android-developers] Re: Extending the webkit or creating webkit plug in

[Matt Kanninen]

You can't extend webkit or the default browser on existing Android
devices, but you can create your own Android distribution and alter
webkit however you please, then install this new firmware on your own
devices or make it available for rooted phones.

You can also ship your own application that features a browser window,
and then track users that way, and in your own application you can do
what what you want with your own cache.

Re: [android-developers] Android >= 1.6: Invalid View object passed to onListItemClick()?

[Romain Guy]

Here's your problem. Views are reused by ListView (so if you change
the background of item #1, it might be reused as item #4 later), this
type of change must be done from the Adapter's getView() method.

[android-developers] List Contact type SIM, Phone, Google

[Nature Boy]

Hi there, I'm aiming to develop an application on Android 1.5 that is
required at one point to list all contacts and display the type of
contact ie SIM, Phone or Google. I can easily list all the contacts by
using

Cursor curAllContacts = getContentResolver().query(People.CONTENT_URI,
null, null, null, null);

And looping through the cursor and I can use code like the sample
below to get fields of data

int intNameIndex = curAllContacts.getColumnIndex(People.DISPLAY_NAME);
String strNameValue = cur.getString(intNameIndex);

My question is, is there any field in the people table or a related
table that holds a value to define where the contact came from (SIM,
Phone or Google)?

Many thanks

[android-developers] Streaming video files endless buffering

[moju]

Hello !

I have a problem streaming live video files. When I stream a file say
of duration 5 minutes, it stops after streaming 2 to 3 minutes and
enters in to endless buffering state. The VideoViews's
OnBufferingListener is endlessly executed, however it shows that the
buffering is not progressing anymore : MediaPlayer's buffer says it
has buffered for example 90% whereas when I call
videoView.getBufferPercentage(), I get something very low, like 1% or
5% ...

After a while in the buffering state, the application crashes. It
seems like the buffering is taking all the memory ...

Does anyone has any idea how to solve this ?

Thanks !

[android-developers] Top of ImageSpan images getting cut off?

[Eldad]

I'm trying to use ImageSpan to add icons to a textview (small
graphics, symbols like emoticons, not much taller than normal letters)
and whenever I have icons on the top line of text they're getting
chopped off at the top. Icons on other lines are fine.

It's like the textview, when calculating its size, doesn't take into
account the icon size.

Any idea how to get it to calculate the size correctly, so the top of
the icons can be displayed?

(sorry for the repost - I tried posting this a couple of weeks ago,
but got no replies)

Is there a way to extend Webkit on Android? Can we write plug in for
webkit in android? Can we do things like creating our own renderer for
a particular type of data embaded in the webpage? Can we track user
session or modify data stored in the browser cache/memory?

Please respond if any has any idea about this.

[android-developers] Re: off-center home screen shortcuts on high-res device

[kcoury]

Hey Dave,

I actually took a look at your source because I wanted to get this
working on my Droid. It turns out that the issue here is that you're
just using the constant value for the dimension instead of using the
getDimension() method in the Resources class and getting the actual
dimension. You could fix this using the following code:

final Resources resources = getResources();
int iconSize = (int) resources.getDimension
(android.R.dimen.app_icon_size);

One thing to keep in mind is that this dimension will still return 48
on the Droid even though high resolution application icons are 72 x
72. Hope this helps.

Kyle

[android-developers] Soft keyboard won't open on custom view in landscape mode?

[Eric Hackborn EH]

I've been experimenting with the IMM and it's mostly straightforward, but for
some reason, my custom view that launches the soft keyboard works only
in portrait mode.  launching it is easy enough:

InputMethodManager imm =
(InputMethodManager)getContext().getSystemService(Context.INPUT_METHOD_SERVICE);
imm.toggleSoftInputFromWindow(getWindowToken(),
InputMethodManager.SHOW_IMPLICIT, 0);

I've seen a couple notes about the soft keyboard only working in portrait but I
assume this was a limitation in a previous version, since all the
Android EditText
views work fine in both portrait and landscape.  Is there some
additional piece of
work needed to enable landscape?

thanks much,
eric hackborn

In case you didn't see it, there's a warning about permissions on the
FBRocket page:

http://xeomax.net/fbrocket/

IMPORTANT: Many people have been experiencing difficulties with this
alpha release, mainly concerning the login functionality. This has
probably been caused by not adding the necessary permissions to your
AndroidManifest.xml file. You need to add the following:

manifest file of your application in order to enable the embedded

AFAIK, no, I am not.

I just do very simple stuff using the available APIs without touching
fancy stuff like caching.

The adapter is ArrayAdapter. The array is a String array. I only
override the following two functions of ListActivity:

@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);

setListAdapter(new ArrayAdapter(this,
R.layout.todo_list_row,
new String[] {
"Phobos",
"Demos",
"Venus",
"Pluto",
"Mercury"
}));
}

@Override
protected void onListItemClick(ListView l,
   View v, int position, long id) {

super.onListItemClick(l, v, position, id);

v.setBackgroundResource(R.color.todo_item_highlighted);
}

The todo_list_row.xml is just:


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

[android-developers] Market access to paid apps on Droid ?

[jarkman]

We've had a couple of reports from Droid users that they can see our
free trial apps in the Market, but not our paid-for ones.

And, as some of them had bought an app on their previous device, they
are understandably anxious to get it onto their new device.

We know it's not afflicting all Droid users, so I am trying to get
some clarity about what is going on. Has this happened to anyone
else ?

I can see a lot of fuss in the market forums about apps being
invisible on unlocked devices (http://www.google.com/support/forum/p/
Android+Market/thread?tid=303d62515914af75&hl=en), but that is not the
case for our users.

Thanks,

Richard

[android-developers] Re: Invoking apps in background when phone starts

[Streets Of Boston]

Yes, it can be done.
But be absolutely sure that your application needs it and that there
is no other way.
If your app/service just tries to save a few seconds on startup-time
when the user (indirectly) activates it, don't do it.

In other words, don't add to the phone's start-up time if it's not
absolutely necessary. It may not be just your app; it starts adding up
to the phone's start-up/boot time if more and more applications start
running some code on BOOT_COMPLETED.

Oh, sorry. Ummm...unless somebody creates a Windows storage driver that
maps over adb or something, I doubt that's possible. Though you might
poke around the documentation for qemu -- the underlying engine for the
emulator -- to see if anything pops up that might fit the bill.

Hello Ranjeet,

thank you for the assist. As  I  am new to all of this,  therefore

the necessary code line  for the ( raw) segment,  video data and
buffer progamatically?   have buffer as frame wise?

[android-developers] Dialog & windowBackground style item

[skink]

hi,

i'd like to create custom Dialog with custom background Drawable.

so i creaded style that defines "windowBackground" item and sets it to
"@drawable/dialog_background":


@drawable/dialog_background
true


dialog_background.xml looks like this:


http://schemas.android.com/apk/res/
android">






where:

@drawable/dialog_bg is nine patch bitmap that defines dialog's
background

@drawable/red_circle is 32x32 png bitmap that contains simple red
circle with radius of 16px and is
offset on the left and top by 16 pixels so that its center is located
on the position (0, 0)
of my dialog

basically i'd like to get something like this:

   *
  ###
 *###*--+
  ###   |
   *|
   ||
   ++

but due to clipping to dialog bounds i got:

   ##*--+
   ##   |
   *|
   ||
   ++

my question is if it's possible to avoid Drawable clipping?

if so, how?

i already tried this:

Window w = getWindow();
ViewGroup decor = (ViewGroup) w.getDecorView();
decor.setClipChildren(false);

but it didn't help...

any suggestions?

thanks
pskink

Mount it as a USB drive. You should have an option to do that when you

[android-developers] Re: How to handle simultaneous key press

[Nightwolf]

You should try it.
At least combinations like "w+a+space" work. I haven't try with
special keys though.
My app that needs to handle multiple key presses has boolean array for
each action (turn left or right, fire etc.). Corresponding array
elements are set in onKeyDown and onKeyUp event handlers.

[android-developers] WebView losing onTouchListener when BuiltinZoomControls are used?

[Patrick]

I have a WebView widget that I'm using to display stuff. I have a
touch listener set up to get taps from it. I also use the builtin zoom
controls (for zooming, of course).
If you don't scroll the view, you can tap and the app acts as
expected. If you scroll at all, and let the controls go away, you can
no longer tap. I have some dummy Toasts for debugging that trigger on
touch events. These work right, then stop working once the zoom
controls do their thing.

So my question is, am I doing something wrong? Is there a "blessed"
way for onTouch listeners and WebView's builtin zoom controls to
peacefully coexist? Or am I just on the complete wrong track for doing
what I'm doing

API Level 3, by the way.

You say no other connections are available so I don't know who useful
this answer would be, but I was able to do this through WiFi and a
cheap router.  The address of the PC socket is the IP address of the
wireless PC port, found through ipconfig.  I have a further posting
pending about difficulty in keep the connection up for the long term,
but that's a different issue.  To connect the phone to the router go
to Settings->Wifi.

[android-developers] Socket - Network connect drops after 15 minutes

[Ron]

I am able to connect to a Socket on my PC from my HTC 1 phone, via IP
and successfully transfer data in a thread that gets rescheduled every
few seconds.  The problem is that after 15 minutes or so, the
connection drops and my debug traces give me the "Network
unreachable".  A further clue is that if I plug in or replug in the
USB cable I get reconnected.

I'm wondering what programmatic function will reconnect to the PC
without having to fiddle with the USB cable.  I've tried
Wifimanger.reconnect and reassociate, neither did the trick.  Perhaps
if I knew what actions were peformmed when the usb cable is plugged in
(which shouldn't have anything to do with my connection) I would be
able to program them into my exception path.

[android-developers] continuous update of a texture

[space]

Hi!

In an application I would like to update the contents of a texture in
each frame. In short, in each frame I need to render to a Bitmap and
then use that Bitmap as a texture in a 3D context.

I tried to use the  GLUtils.texImage2D(GL10.GL_TEXTURE_2D, 0, image,
0) call, but it seems that it keeps eating memory (after a while the
app is killed due to out of memory).

Also, I wonder if this is the fastest solution?

And a third question: is it possible to render into a texture with
opengl?

Thank you in advance!

[android-developers] Urgent Position for Android Developer | Telecommute

[Navneet Chalana]

Hello Friends,

Hope you are doing great,

I am currently in search of an experienced Android Developer who could
doan Android port. If you are available and looking for new projects.
Please send resumes to navn...@okayainfo.com or call me at
631-685-1134 X 260 for further discussions.

Project Details:

We're currently working on versions for S60v5 Touchscreen and iPhone,
so we'll have skins for touchscreen devices.  We'll also have a
graphics pipeline for OpenGL-ES 1.1 and OpenGL-ES 2.0.The front-
end source is all vanilla C, using very few external libs:  libc and
zlib.
