Re: [android-developers] Cursor LifeCycle

[Dianne Hackborn]

If you are closing the cursor yourself, you really shouldn't be having the
framework manage the cursor at all.  I mean...  the point of having the
framework manage the cursor is for it to close it (and otherwise manage it)
for you.  If you are then going to try to close it yourself, you then get
to fight with the framework about who owns it.

Also, loaders are not tied to content providers.  If you have something
else to load, you can make your own subclass of AsyncTaskLoader.

That said, the framework is really oriented around accessing data through
content providers.  I think you'll find it simpler to just go with that
rather than having to build up the various conveniences it already provides
for them.

Re: [android-developers] Fragments

You can't.  That is not what fragments are for.  And please stop posting
that link.  That is someone's hack on Android to add features that are not
in the current platform, so not a topic for discussion on this list.

Your reply seems to indicate that you have some rather indirect concern.



I don't know I get what you meant by the above statement. As for me, I am  
thinking that once, say SMS/MMS, comes in, I just to transfer to my pc  
immediately.


Dalvik Debug Monitor Server (DDMS) seems to put the phone into debug mode,  
as the name suggests. Normal practice says once you are finished with it  
stop the service since it is for debugging only.


The term 'indirect concern' you suggest some evil motives, don't you ?

[android-developers] Re: No luck with new ICS CalenderContract

[Zsolt Vasvari]

Great -- thanks.

So I just moved my code over.  My observations of the new Calendar
Content Provider vs. the one from SDK 8:

- Same URI
- Same logic works for reading the list of Calendars and creating/
reading Events and Reminders (only operations I am doing).
- A couple of the column names have been changed -- they have been
prepended with "calendar_"

So, in other words, if you just fix up the column names, the same code
works as before.

If your program is no longer debugging (ie, doesn't have a remote debugger

it, and only see slowdowns when there's a debugger actually attached to it.

[android-developers] Re: Re: Android and WinXP: look for some tips

[SL]

What do you mean?  You can use Android phones for development.  That
doesn't mean they are in some low-level debugging mode.



Assume that I have an Android phone plugged onto a winxp pc via a USB  
cable, and my program on winxp is running 24/7.


I am just wondering whether it is appropriate to let the phone on  
debug-mode all the time (because my program is no longer debugging).


Your reply seems to indicate that it is not running in the debug-mode.

Re: [android-developers] monkey wrench in the works ...

[Dianne Hackborn]

Sorry, I have no idea what you are talking about.

You stash away your state in onSaveInstanceState().  You get it back in
onCreate().

This is not directly related to onPause(), and definitely has nothing to do
with any  kind of constructor written like you show.  (In fact I would
strongly recommend not having a constructor at all on an Activity, it is
mostly a path to what you don't want.)

That is largely the definition of an IntentService. Once
onHandleIntent() completes its work on the background thread, the
service shuts down. Or, as the IntentService JavaDocs puts it:

"IntentService is a base class for Services that handle asynchronous
requests (expressed as Intents) on demand. Clients send requests
through startService(Intent) calls; the service is started as needed,
handles each Intent in turn using a worker thread, and stops itself
when it runs out of work."

You are incorrect in your interpretation of startForeground().

Re: [android-developers] "lights out" mode PLUS menu soft key?

[Mark Murphy]

Put a menu in your UI. If you don't want it in the action bar (because
you have no other need for the action bar), that's fine -- put a menu
button somewhere in your UI that your users will find and use. Or
don't use menus, but rather some other UI paradigm (I haven't
encountered many games that use native options menus).

[android-developers] monkey wrench in the works ...

[BCS]

I saw this on a post from last January ~ monkey wrench in the works
represented by Android's handling of image data outside of the Java
heap ~ seems simple enough to do aggressive nulling but it does not
sound like Android is doing the right thing here

given that the docs state Activity Lifecycle Android will work on the
idea that onPause() will be called in anything other than "brutal-
dump" then one can write to Bundle and get it back when focus returns
to the application

thus we could just check objects for null and if Object != null
then  would the value have been retained?

seems rather simple - what gives?..

Object value;

MyClass(){ if (value == null) { value=new Object(); } }

then if user wants to flip the phone around maybe we ^do^ need a new
Object()

maybe not

[android-developers] Re: Nfc Foreground Dispatch

[bjthe4th]

Thanks, I had been switching between some different Intent Filters and 
hadn't returned it to proper format. I had changed the mime type and had 
forgotten to change it in the manifest. And I had left the "l" out of 
. Thanks for getting me to take a second look at it!

For external types I have figured out how to do it. If anyone else is 
wondering how to do it, here is what I did.

Manifest file:




   

Setting up the Foreground Dispatch
mPendingIntent = PendingIntent.getActivity(this, 0, new 
Intent(this, getClass()).addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP), 0);
IntentFilter ndef = new 
IntentFilter(NfcAdapter.ACTION_NDEF_DISCOVERED);
try{
ndef.addDataScheme("vnd.android.nfc");
ndef.addDataAuthority("ext", null);
ndef.addDataPath("/mysite.com:a", 0);
}
catch (Exception e)
{
throw new RuntimeException("fail", e);
}

mFilters = new IntentFilter[]{ ndef };

  I hope it helps someone!

Re: [android-developers] Stop service when next time app is started

[Kristopher Micinski]

Do you know how to start a service?  you do a startService() on a context...

Stopping the service is now literally calling a stopService() on the context...

So now all you have to do is call these methods.  You might think that
you have to keep the global application state around, but this isn't
really so bad, because your app and the service are both running at
the same time (i.e., they are *not* separate processes, it's just that
what you see in an activity is what people usually think of as the
app..., the service will run within your app!)

[android-developers] Has something changed recently with how the Market processes the Manifest File

[tschallb]

Hi Folks,

We are seeing some strange behavior with how the Market processes our
Manifest file.  This weekend we noticed that our list of available
devices dropped from 590 to 196.  If I then take a look at the Device
List itself I now have devices that can no longer Enable or Disable
manually as they are an "unsupported device due to your manifest
settings".

Has anyone else noticed this behavior recently?  Has there been any
new Filter Parameters added?

The Required device features shown are:
 android.hardware.location.network
 android.hardware.microphone
 android.hardware.location
 android.hardware.touchscreen
 android.hardware.screen.portrait

Our Manifest has the following:

...

Tim

[android-developers] Re: Nfc Foreground Dispatch

[krohnjw]

WRT addDataType(string) I've only used it with mime types so I'll let 
someone else comment on the best practice here.


As far as the mime based filter, the more specific filter should start fire 
first.  If you have specified your app as default, for the correct action 
and for your specific mime type it should launch with no competition from 
other apps (no chooser dialog).

Were you specifying the filter in the manifest or at run time? 

Here's an example mime based filter to be specified under the activity in 
your manifest:

 

 
 


I use this type of filter in a few different apps and have yet to have any 
issues with my app(s) not starting when the tags are read or presenting the 
chooser dialog.

[android-developers] Displaying Percentage Text inside Android Progressbar

[Ryan]

In order to display a percentage text inside Android's progressbar,
you will need to set up a .  Give the RelativeLayout
parameters followed below:

android:layout_width="200dip"
android:layout_height="30dip"
android:padding="0dip"

Then close your RelativeLayout.  Inside your layout, insert your
 with following parameters:

android:id="@+id/youridgoeshere"
android:layout_width="200dip"
android:layout_height="30dip"
android:layout_centerInParent="true"
style="?android:attr/progressBarStyleHorizontal"
android:indeterminateOnly="false"
android:max="100"

That's all for the progressbar, now on to the percentage text.  Create
a  inside your layout and give it the following parameters:

android:"@+id/youridgoeshere"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:textColor="#00"
android:textStyle="bold"

Close your TextView and there you have it!!! Your text should be
centered horizontally and vertically inside your progressbar.  The key
is to set up a relative layout while keeping it the same width as the
progress bar. Then using the parameter "centerInParent" keeps both the
progress bar and textview in the center of the relative parent.  Hope
this helps out. Enjoy!

[android-developers] Android service killed immediately after start, despite calling startForeground()

[Chris]

Hi,

I'm having a problem with my IntentService. Every time I start my
service, the onDestroy() method is called as soon as the service
becomes idle. I set up my service to run in the foreground, and
despite this the service is still being killed right away. I have only
one other activity in my application, and it is not calling
stopService().

Reading the developer docs gives me the impression that calling
startForeground() will allow your service to persist, even when idle,
except when there is an very high demand for memory, or am I reading
this wrong?

My code below:

public class FileMonitorService extends IntentService {
  public int mNotifyId = 273;
  public FileMonitorService(){
super("FileMonitorService");
}

@Override
protected void onHandleIntent(Intent arg0) {

}

@Override
public void onDestroy() {
Toast.makeText(this, getText(R.string.toast_service_stop),
Toast.LENGTH_SHORT).show();
stopForeground(true);
super.onDestroy();
}

@Override
public int onStartCommand(Intent intent, int flags, int startId)
{
Notification notification = new Notification(R.drawable.icon,
getText(R.string.notification_short), System.currentTimeMillis());
notification.flags|=Notification.FLAG_NO_CLEAR;
Intent notificationIntent = new Intent(this,
FileMonitorActivity.class);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0,
notificationIntent, 0);
notification.setLatestEventInfo(this,
getText(R.string.notification_short),getText(R.string.notification_long),
pendingIntent);
startForeground(mNotifyId, notification);


Toast.makeText(this, getText(R.string.toast_service_start),
Toast.LENGTH_SHORT).show();
return super.onStartCommand(intent, flags, startId);
}
}

Thanks for any suggestions.

Cheers,
Chris

[android-developers] BT headset profile customization

[Ronnie R]

Hi,

I have been working on Bluetooth (BT) profiles to develop a module in
order to play with AT commands that would allow me to do following to
tasks:

1. Need to develop a wrapper that would help be setting up priority of
responding to BT client service discovery request instead of native
device/OS service module accept and acknowledge the BT client service
discovery request.

2. As Android OS 3.0 and above provide public API to access the BT
headset and handfree profile, that would allow access the BT h/w
through proxy, run AT commands to to find and authenticate the
headsets and recognize the voice for BT voice streaming. The problem
that i am facing and to define a class at application level using
these API calls with in the application search for available BT
devices based on available Servicediscovery module and reverse the
authentication process between BT client and BT server so that instead
of device giving accepting client and declaring the client as handfree/
headset, BT server itself becomes the client/headset and other BT
connected device (client) can receive the commands.
I have created the BT discovery, voice stream communication (working)
and handshaking the headset profile as provided by API however unable
to find the reverse work around, please suggest if this Android API
framework provide support such level of customization and is feasible.

Regards
Ronnie

[android-developers] Ideas for optimally developing a game with lots of animations without using openGL

[JustTheTroll]

So I' d like to develop a game that involves a lot of animations (like
>1000 frames made from images in 320*426 format). I already tried one
shot at it by creating sprite classes that have arrays of id's for
each frame from the res/drawables/ folder needed by the sprite). Using
2 sprites each of approximately 32 frames i got within 100kbytes from
going over heap budget (i used debug.getnativeheapsize/freesize/
allocatedsize to track my progress).
I also tried using animations created from animation-list xml's (=> it
went over heap budget).
Oh, also, my game will also make use of sounds.

Any suggestion is extremely welcomed. Thank you ^ ^

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

[Eric Carman]

Hello Dianne,

I don't have access to the physical devices, but the Motorola emulator was 
very helpful. I agree with your thoughts that the multi-touch keyboard 
might be at the root and I've posted to the Motorola forums with the sample 
project that demonstrates the issue. Hopefully they will take a look and 
make a determination as to where the issue actually lies.

But, on a more positive front, I took you advice and did some research on 
the onCreateInputConnection. By adding the following to my component, the 
problem has resolved itself. I got it to working on the Motorola emulator 
and a couple of very helpful customers tested it on their physical devices.


@Override
public InputConnection onCreateInputConnection(EditorInfo outAttrs) {
return new BaseInputConnection(this, false) {
@Override
public boolean sendKeyEvent(KeyEvent event) {
return super.sendKeyEvent(event);
}
};
}

Thank you again for your advice and participation in this forum. I am AGAIN 
extremely grateful for your help.

Best Regards,
Eric

[android-developers] "lights out" mode PLUS menu soft key?

[thedude]

I am trying to add "lights out" mode to my game, but cannot get it to
coexist with the "menu" soft key, which I still need to be accessible.

To elaborate,  setSystemUiVisibility(View.STATUS_BAR_HIDDEN) seems to
have no effect unless I also target sdk version 11 in my
AndroidManifest (), which has the side effect of hiding
the menu soft key.

Any ideas?

Thanks,

Re: [android-developers] Re: Incorrect output values with gluUnProject… why?

[Romain Guy]

OpenGL ES (1.0 and 2.0) does not offer a way to read the depth buffer. You
can fake it in 2.0 by using a custom shader to render the scene in an FBO.
Here's the fragment shader I've used in the past to achieve this:

// uniform float UNI_near;
// uniform float UNI_far;

void main() {
// Non-linear depth value
float z = gl_FragCoord.z;
// Near and far planes from the projection
float n = UNI_near;
float f = UNI_far;
// Linear depth value
z = (2.0 * n) / (f + n - z * (f - n));

gl_FragColor = vec4(z, z, z, 1.0);
}

Re: [android-developers] In-app billing: Creating coupons ?

[Kostya Vasilyev]

In-app billing does not allow free (of charge) items. You can refund a 
purchase once it's been completely processed (i.e. the money actually 
changed hands) and keep activation (it's up to the application code to 
treat refunded items as active: Dungeons does this).


There is no expiration date either, although you could try unpublishing 
the item in the Dev Console - don't know if this affects existing 
transactions; it might. This assumes that the app does a restore 
transactions once in a while (which is subject to throttling on Google's 
side).


Some similar requests for enhancements have been filed:

http://code.google.com/p/marketbilling/issues/detail?id=12

... but not specifically for coupon type functionality. You are welcome 
to do so (but I wonder if it makes any difference).


At this time, I'd go with some other solution, perhaps an activator type 
application that could be installed alongside the main one, and would 
talk to your own server.

Actually, if you're stuck with GL ES 1.0, unfortunately I'm not aware
of a way to read the depth buffer. I'm no expert on legacy GL ES
though so you might want to consider asking on a GL ES forum -
although there might not be a direct way to read the depth buffer
under GL ES 1.0 someone could know a work-around.

If you can't use GL to do the unprojection you can still compute it manually.

[android-developers] In-app billing: Creating coupons ?

You can't as there's no "old time" concept there. You simply get
notification that time has changed and that's it.

[android-developers] The new KeyChain API

[fba]

Has anyone out there attempted to use the new KeyChain APIs?   They
don't seem to work the way I would expect.

I am able to install a certificate easily enough using
KeyChain.createInstallIntent(), and passing it a PEM formatted
certificate.

The documentation indicates that you need the USE_CREDENTIALS
permission in order to read any certificate data back.  So, I have
enabled that. However, once I go back and try to read out the
certificate data with KeyChain.getCertificateChain() I get the
exception "java.lang.IllegalStateException: uid 10040 doesn't have
permission to access the requested alias".   Looking at the
documentation indicates that you need the USE_CREDENTIALS permission.

Has anybody made something like this work?


In trying to figure this out, I dug a little deeper to see what I
could find.   When I got a shell to the emulator, I found that my
certificate had been installed in two places.  One was in /data/misc/
keystore, and the other was in /data/misc/keychain/cacerts-added.
The new certificate also shows up in the Settings->Security->Trusted
Credentials->User.   So, the certificate appears to have been
installed correctly.

Digging around a little more found the database in /data/data/
com.android.keychain/databases.  This database looks like it is
supposed to handle the permission mapping for certificates that are
installed.  So, for fun, I added an entry to the database that I
thought should give uid 10040 access to the certificate with the alias
of "Testing".  ("Testing" is the alias I used to install the
certificate in the first place.)   When I run my test app, I no longer
get the "uid 10040 doesn't have permission..." error.  However, I now
get this error : "java.lang.IllegalArgumentException: bytes ==
null".   This change in errors would seem to indicate that my theory
about the permissions is correct, but even when it is fixed the
certificate still won't be returned to me.

Any help would be appreciated.

[android-developers] Re: Need help on connecting android app to remote database.

[fba]

Hi Charan,

There isn't an easy way in Android to access a remote database.   I
suppose you could dig around and figure out how mysql communicates
across the network, and then develop an interface from there.
However, it seems that would be pretty involved.

I had a need to do something similar with a previous project.  The
"easiest" way I could find was to hack up a little PHP to run on
Apache that would output the data I needed in XML.   I could then put
the XML through the SAX parser, and end up with the data I needed.   I
suspect something like this is going to be your best bet.

Re: [android-developers] Re: No luck with new ICS CalenderContract

[Michael Chan]

Hi,

There just isn't a *supported* way via the Android Calendar API. (You
can always do some reverse engineering and get something that work for
now. But it may break suddenly one day when the user gets an update.
So I really really want discourage everyone from doing that.)

> Is there a better, more supported way to do this?

The only supported way today is to talk to the server directly via the
GData api.  You need to figure out how to get the credentials.
http://code.google.com/apis/calendar/data/2.0/developers_guide.html
Looks like the code below is doing that.

2 way:
1) Instruct the user to do it manually
2) Send the user to
https://www.google.com/calendar/render?cid= or
http://www.google.com/calendar/hosted//render?cid=. The user has to say they want to use the desktop UI, zoom in, and
click "Yes, add this calendar". It is not a great experience.  The
other drawback here is that the user won't be able to choose which
account the calendar should be added to.

Mike

[android-developers] Tools for adding print Logs inside the Android Code

[s.rawat]

HI,
I am trying to understand the android code flow for camera module.Is there
any script to insert the print logs(FILENAME_FUNCTIONNAME_LINENUMBER)
inside the android code(java , cpp and c files) .I am planning to do this
and compile the image and run it and logcat the output while I run the
camera.apk application.Is it fine to do this sort of code analysis.I know
task is cumbersome , any other drawback for this approach.Plz assit.
Rgds,
Saurabh

[android-developers] remap hardware buttons for UI navigation

[lbendlin]

On the Parrot Asteroid there is only a scroll wheel that creates the 
keycodes 19 and 20 for vertical navigation. The device also has media 
buttons, specifically 87 and 88. I would like to translate these into the 
horizontal dpad keys to allow users the selection of buttons that are in a 
row.  I tried this

   @Override
public boolean onKeyDown(int keyCode, KeyEvent event) {

if(keyCode == KeyEvent.KEYCODE_MEDIA_PREVIOUS)
keyCode = KeyEvent.KEYCODE_DPAD_LEFT;
if(keyCode == KeyEvent.KEYCODE_MEDIA_NEXT)
keyCode = KeyEvent.KEYCODE_DPAD_RIGHT;

return super.onKeyDown(keyCode, event);
}


and while the keys are properly recognized they don't seem to translate 
into shifting the focus. Any ideas?

[android-developers] Re: Directing user to webpage, then back to app

[Neilz]

Ah... it works when I run it from your sample page, yes. It doesn't
work from a WebView, hence my initial confusion.

At least I have the principle working... I can't actually test it in
full, as I want to pass parameters too, but don't have a webpage I can
manipulate at this moment.

Thanks for persevering...

Right, so if I'm looking at the correct part of the sample, you end up
logging a strange 'intent' url, like this:

intent:#Intent;action=com.commonsware.android.MY_ACTION;end


That strange URL is the result of calling intent.toUri().

http://developer.android.com/reference/android/content/Intent.html#toUri(int) 



Basically, you can make your own Intent in code, call toUri, and copy 
the result to the web page source.


Or just replace the action with your own, keeping the rest (from 
"intent:" to "end").



I'm not sure what I do with this... I've tried using it in a link, as
another sample suggested, but I just get a 'Web page not available'
error. Here's my own example:
webView.loadData("Hello
World!", "text/html", "utf-8");


com.commonsware.android.MY_ACTION matches the intent filter for the activity in 
Mark's sample code.

Your action string should match the intent filter in your project, not Mark's.

[android-developers] Re: Custom file viewer

[chrisn]

Mike Murphy:

Thanks for the reply, writing my own *second* activity is the path I
will go down if I can't get this to work.

I don't think that this is good general practice if the intent filter
API is working as documented.  It pollutes the android device with
needless activities that work like file browser but are hardcoded.
This breaks the abstraction that intents were meant to provide and
obviously doesn't allow users to specify a different activity to
handle said file format.

I guess I am looking for acknowledgement that this doesn't work as is
documented *or* that I am doing it incorrectly.  Multiple people have
gone down this path and there are several threads on this group that
makes it seem like it works in some places and doesn't work in other
places.  One other thing I didn't mention is that I am using a version
of Gingerbread that NVIDIA is using.  So this bug may be fixed a while
back and I could just be out of luck until ICS is running on my
hardware.

Specifically, I would state this problem a little stronger than I have
so far.

Write a simple activity, perhaps all it does is log which file it is
started with.  Add a intent filter that tries to map this activity
view to a file with a given extension *but doesn't map this activity
in any other way*.  This file format needs to be completely
unregistered in the system any other way, webkit or otherwise so pdf
isn't an option.  Attempt to launch the activity with am just
specifying the category and the file.  It will not work and it should,
given the documentation around intents and intent filters.

Then pick up one of the may file browsers attempt to double click on
the file.  This also will not work; and this failure in the public
android API is leading to app pollution because people are just
working around the problem by writing half-done versions of file
browsers hard-coded to their desired activity.

Right, so if I'm looking at the correct part of the sample, you end up
logging a strange 'intent' url, like this:

intent:#Intent;action=com.commonsware.android.MY_ACTION;end

I'm not sure what I do with this... I've tried using it in a link, as

error. Here's my own example:
webView.loadData("Hello

[android-developers] Re: Incorrect output values with gluUnProject… why?

[saex]

Yes Latimerius, i think that i dont have to pass 0 as winZ parameter,
but i dont know how to get the Z value from the depth buffer. I'm
programming for Android 1.5 and openGL ES1, i didn't find a working
way to obtain winZ value on google after hours of searching :(

Did you know how to do it?

Re: [android-developers] Incorrect output values with gluUnProject… why?

[Latimerius]

I haven't ever used gluUnProject() myself but unless your geometry is
glued right to the near plane I'm pretty sure it's wrong to pass zero
for your window space Z.  Unless you have special knowledge of your Z
I guess you'll need to read that value from the depth buffer.

Re: [android-developers] Incorrect output values with gluUnProject… why?

[Daniel Drozdzewski]

You coordinates are wrong for the screen/window coordinates, but how
do you know that those are not the object coordinates?

Right, I see. No, the path option doesn't make a difference, it still
offers me a choice of apps to open with.

Ok, it's the other approach that I'm struggling to find an example
for. Just lots of messages discussing it! The appears to be an example
on the following page, but it simply doesn't work for me:

[android-developers] Incorrect output values with gluUnProject… why?

[saex]

I have a simple Square with openGL es 1 and Android 1.5. The square is
painted on the center of the screen.

I want that when the user press on the screen, or moves the finger on
the screen, the square get's moved to that position. For do this i
tryed with GLuUnProject, i tryed to obtain the opengl coordinate that
matches with the window XY coordinate touched with the finger (to
translate the polygon to that coordinate in the future), and i'm
writting the coordinates on the LogCat.

The coordinate's i'm receiving are not true cordinates, are wrong
coordinates. For example this logcat represents a horizontal movement
to the right of the screen:

[android-developers] Re: Nfc Foreground Dispatch

[bjthe4th]

Okay, I found out what I believe to be the proper way to format The 
external type (It is stored as a uri) but it doesn't seem to want to work.
This is how I set up the Foreground Dispatch for my tag:
mPendingIntent = PendingIntent.getActivity(this, 0, new Intent(this, 
getClass()).addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP), 0);
IntentFilter ndef = new 
IntentFilter(NfcAdapter.ACTION_NDEF_DISCOVERED);
try{
 ndef.addDataType("vnd.android.nfc://ext/example.com:a");
}
catch (Exception e)
{
 throw new RuntimeException("fail", e);
}

Does anyone know if ndef.addDataType is the proper method to use to add a 
uri? I haven't found any examples of filtering based on any other Ndef type 
other than MIME. Using other apps, it detects the type of my card just 
fine, but I am unsure about how to format the Foreground Dispatch.

Also, when I was trying to start up using a MIME filter for Foreground 
Dispatch, I noticed that my app was always competing with other apps to 
start, and this was with a very specific MIME filter. After the first time 
I chose it, the app would start up when ever I selected the card with the 
app off, but until then others would compete with it. Does a specific MIME 
type trump the wild card "*/*" or if other apps use the wild card will it 
always compete with a custom app? 

Thanks to anyone who can help!

[android-developers] Re: A quick hint as to where to start for a sliding box?

[DismalSeas]

Another thought is that there is the potential to build a flash
application outside the Android platform and then import that flash
application and run it.  I still haven't gotten the grasp around when
to use external graphical options such as OpenGL and when to use
Flash applications. Are these typically here for when people are
accustomed to using a particular language or need specific features?
If I were a Flash or OpenGL developer it would sound as though these
would be appealing, but at the moment they do not sound that
appealing.

Correct. You will note that in Ms. Hackborn's answer, she cites two
approaches to the problem. You are taking one approach. The quotes you
used are for the other approach.

BTW, try putting an android:path attribute on your  element and
see if it then only opens up in your app vs. giving you the chooser. I
know this works for NFC and NDEF and I can never remember if it works
for HTTP URLs as well. I know that this is what Barcode Scanner uses
to initiate a scan fro

Hmm, I don't get it, I'm missing something obvious :-/

At the moment I have a webview (which is mimicking what may be a stock

Then I have this in my manifest:


  
  
  
  



There isn't anywhere for me to be creating, or setting properties on,

[android-developers] Real-time audio capture and streaming on Android ... the latency problem ?

[Emre A. Yavuz]

Hi,
 
We would like to capture audio using the MIC on the phone and stream it to a 
laptop/desktop to play it in real-time. We have a RTSP server on the phone and 
a RTSP client on the laptop/desktop. The client side is supported by the 
Live555 streaming library and the MPlayer. We have a code working at the moment 
which does the job, however our concern is delay as you might have guessed. 
Real-time requires a low latency. I've done some search, but I haven't seen any 
concrete solution online so far.
 
Can anybody recommend where to look for ? A link to a library, suggestions etc. 
 
With regards,
 

Emre

[android-developers] Delegate TouchEvents from WebView

[Philipp]

Hi, I have a problem:

I have a ViewGroup (LinearLayout) that holds one or more Fragments,
each containing a WebView.
I have a custom OnTouchListener for my ViewGroup that will react to
special events like touches on the screen borders. If none of these
special events is detected, the touch event should be passed to the
WebView.
The problem is that the WebView is the first element to get the touch
event and there does not seem to be a way to delegate the touch event
to the underlying View.
How can I modify the touch hierarchy in a way that the ViewGroup
receives the TouchEvent first and only if it doesn’t consume the event
it is passed to the WebView?

I made an example project to illustrate my problem at
https://github.com/pcomans/WebViewTouchTest

I have chosen to add two fragments containing a WebView in order to
make clear that it is not enough to just override the
setOnTouchListener of the WebView instead. I am interested in the
absolute position of the touch. Sure I could probably calculate the
absolute position from the relative position but this is not an
elegant solution.

I would really appreciate any help!

Best,

Philipp

"your own scoped action" would be, say,

Um, that seems straightforward enough. Call setPackage() with the
package name of whatever app should contain the recipient of the
Intent -- no other app's components will be considered.

No, but you are in charge of the URL that you are redirecting to.
Those passages pertain to the use of an intent: URL, generated via a
call to toUri() on a properly-constructed Intent. You would redirect
to that URL.

[android-developers] Re: Directing user to webpage, then back to app

[Neilz]

Thanks Mark. Now that I know what to be searching for, I've found
several similar topics mostly on stackoverflow.

Most topics have a response by Hackbod, stating not to do it that way,
but I'm struggling a little to understand what it is he's suggesting
instead.

http://stackoverflow.com/questions/3469908/make-a-link-in-the-android-browser-start-up-my-app

So far I've got an example link from a WebView to open up the 'choose
application' selector, which does at least contain my app - but I want
it to open my app automatically.

I don't get this bit:

"The best way to use this, if you want to ensure it launches only your
app, is with your own scoped action and using Intent.setPackage() to
say the Intent will only match your app package."

and also...

"Finally, you may want to set the package of the intent to your app
with this: 
http://developer.android.com/reference/android/content/Intent.html#setPackage(java.lang.String)

This is a newer feature in the platform, which allows you to direct
link intents to only your app so that other applications can not
intercept and handle them."

Where exactly is he suggesting that I use this? My link is going to
come from an external browser over which I have little control.

You're talking about "compatibility mode version 1".

It's not something to aim for, really.

It is a limitation of the underlying qemu environment, in concert with

In theory, if you have the browser redirect to some URL that is
handled by your app (ACTION_VIEW, CATEGORY_BROWSABLE, and an
appropriate  element), you could accomplish this with your
"code" baked into the URL (e.g., /postaction/success and
/postaction/failure). I haven't tried a redirect as the trigger
mechanism, though.

Hi all. From my app I want to send the user to a web page to complete

How can I achieve this? Will I have to use a WebView within the app,

[android-developers] Re: Development platform

[aesptux]

I suggest Fedora 15 (Fedora 16 is coming out in two days) as the best

I'm currently using it (I changed from Ubuntu) and I'm happier with it.

Best regards,

Adrián.
