[android-developers] AlarmManager with alarm icon

2011-01-19 Thread Andy Savage

I'm setting wake up alarms for a custom app using
AlarmManager.set(). This correctly registers an alarm and the
app is launched at the desired time. It doesn't however give a visual
alarm indicator in the notification bar (RIGHT hand side, next to the
time). How do I set this?

I have seen 3rd party alarm apps which trigger this icon to display.
They also cause a toast along the lines of Alarm scheduled for x
hours from now, which may be part of the process. Obviously it's
quite easy to generate that toast manually, but I'm wondering if that
is integrated too?

Thanks.

2011-01-19 Thread Andy Savage

It's not a notification as far as I can tell. It appears on the RIGHT
hand side next to the time (Along with the other in built icons,
such as battery, connectivity etc). It doesn't appear in the app
specific list of notifications on the LEFT, or the notification drop
down list, or have associated text.

 AlarmManager is for alarms. Not alarms + icons + shower + cofee :)

 If it's easy why should it be integrated? To make more problems in
 case you do *not* want it? Framework/OS gives you single bricks,
 not whole walls. And it should be that way, for many reasons incl.
 fexibility.

[android-developers] Re: EditText inside ListView

2010-12-19 Thread Andy Savage

In case anyone wants to quickly replicate this to check it, I have an
example project at: 
http://andysavage.homeip.net:2886/EditTextListViewDemonstration.zip

To replicate simply run the app, and try to type text into any of the
edit boxes. Using the emulator, when I first touch an EditText the
software keyboard popus up and focus is lost. I can then re-touch the
edit text, but as I try and type the software keyboard's predictive
text will be shown and the edit text will again lost focus, and
recreate itself.

[android-developers] EditText inside ListView

2010-12-18 Thread Andy Savage

I've found a plethora of older unanswered questions about this, so I'm
adding one more in the hope that someone has now found a solution.

I have an EditText inside a ListView (Specifically its in a custom
Preference inside a PreferenceScreen, but a simple ListView is enough
to replicate it). When the EditText is touched, the software keyboard
is popped up and the EditText loses focus. You can retouch the
EditText and try to type, but when the predictive text suggests a word
it again loses focus and empties itself.

Upon inspection the EditText's parent view is being recreated, which
explains the losing focus and content. Digging a little deeper
Preference's getView(View convertView, ViewGroup parent) is being
called with a blank convertView, rebuilding the entire view rather
than reusing the existing one. I don't know if that's the right place
to be looking, or if that is normal for a ListView child. The view is
also recreated as the user scrolls (which makes scrolling somewhat
slower, but that's another issue).

I don't really know where to go from here. A PreferenceScreen expects
a ListView so I can't just change the view to LinearLayout or
something. I also don't really want to give up the custom EditText
preferences as they fit very well in the context they are being used.

Any ideas on how to stop this issue would be great.

[android-developers] C2DM Tied to Market? (e.g. will it work on non-official devices)

Hi everyone,

Quick question.

Just wondering if Cloud to Device Messaging (C2DM) is available for devices
that use Android 2.2 but don't have the Android Market installed (because
they are not an official device).

Is this service tied to the Market?

[android-developers] Developing a project on both Android Windows

2010-08-10 Thread Andy Savage

Hi everyone,

I've got an interesting request that's hard to find information on Google
for.

I'm developing an application across both Android and windows which (mostly)
shares the same classes. I was looking for a really easy way to duplicate
some of the special Android classes on windows.

For example for the Log class, I wrote a MyLog class which performs exactly
the same but the actual class does different things (for example on windows
it just formats a string and writes it out to System.out).

I was wondering if anybody had any classes which performed similar functions
to Android in windows. For example, I'd love to have a drop in replacement
for the Broadcast system in Android that I could use in windows to get
very similar functionality.

Just wondering if anybody had any small classes they could share or any
links to something which duplicates even a small part of what Android does.

Cheers,
Andy

Re: [android-developers] an experiment in open development: Vdroid

Hi there,

Just wondering if you can tell me what Vdroid does? I'm interested in
anything related to video recording and playback but I can't find this
package anywhere (I'm only using a developer phone so I can't see paid apps

Couldn't find any screenshots or information.

Looking through the source code it just seems to use the inbuilt media

clarify the use of Vdroid?

I'm looking for a solution that will help me to play back raw video data.
Will this help me?

I've enabled the SourceForge BB so we can talk in a public forum.

It is my hope especially that those of you with more advanced hardware
will test it out and help me make it work. I know of one user with a

Re: [android-developers] Filter for crapps (crap apps)

2010-06-29 Thread Andy Savage

+1 for this. It's kind of ridiculous.

One of Apples major arguments for moderation is that the Android App store
has lots of crap in it including pornographic stuff.

Whatever your view towards that kind of stuff. It would be really nice to
filter it. When I search for facebook chat, or gmail I don't want a whole
lot of sexy asian picture apps!
Sometimes the good apps get pushed way beyond my tolerance level to sort
through.

It would also be GREAT to sort apps by rating (with apps that have the
highest rating via number of votes first), that could help also.

Re: [android-developers] Re: Avoiding GPL

2010-06-27 Thread Andy Savage

From a technical standpoint presuming the GPL licence allows it (I'm not a
lawyer and I don't pretend to be one) you might want to consider something
like OpenIntents.

http://code.google.com/p/openintents/

This could allow you to link two unrelated packages together in theory (I
think).

But I was referring to MySQL, not the connector. Also, sure there will
be also corporates who pay for not using the GPL, but my point was
that one is not forced to pay to use it. Now I think we are made clear
our points, and MySQL was only an example.

And; the INTENT of MySQL is that if you use the GPL version of the
MySQL database, your application should also be GPL. But, of
course, there are loopholes. However, using these loopholes in a
way that is obviously a circumvention is against this INTENT.

If you want people to respect YOUR intellectual property, you
should respect others as well, and not exploit their software in an
unintended manner.

Licenses arbitrate how much land each entity has the right to own, in
other words they establish borders in a objective way that everybody
agrees on, not a subjective or moralistic one. So while I personally
might have some interest in what other people are willing to do
(subjective and moral position), not everybody is compelled to do
that, but only respect the law. Everybody uses licenses to try to
place that border in the most convenient possible way. An author of
FLOSS software tries to place the border in the best possible position
in his perspective, and a user of a FLOSS software has the same right,
in his perspective.

PS MySQL intent was to make money, and GPL is one of the best way to
do that, because of the double licensing thing. In fact, they made a
lot of money. Note that the owner of MySQL has changed many times and
the intents of the original founders, of Sun Microsystems and Oracle
might have been changed. Frankly, if I used MySQL I wouldn't be
interested in what their intents are, only in what I can do.

Re: [android-developers] Re: Avoiding GPL

2010-06-24 Thread Andy Savage

Ignoring the legal ramifications here. Let me say my opinion.

I think that we need to be quite wary of the licences of each app and
whether they are conforming to it. Obviously this person intends to try and
not conform to it (if they can figure out how).

But let me give you an example of why this in general is a bad idea.

I have gone through some trouble to try and find a way to play DivX/xVid on
Android for my app and I think that much of my time and trouble wouldn't
have been wasted if people were more strongly conforming to the software
that licences are released under.

Take RockPlayerBase for example, this app (which is in beta) plays DivX
and xVid. It's not magic, it simply does this by ffmpeg (I can tell by
checking the library names in the pcakge). I have no website (in English
atleast) to request this, but when it gets released I will be requesting
they they conform to the LGPL source and release instructions on how they
compiled it for android and the changes (if any) they made.

Whats really frustrating is that they didn't release these instructions at

As usual I don't want to open source code for full application.

Now what I understand is if I make two separate process one with my
main application code and other as a service or something with Open
source library then in that case I have to open source code only for
the other one.

Now the question is what is the best way to do so in Android.

Suppose
My Main App is A
Open Source code is B

So A will give some data to B. B will process this and sends data back
to A. B may not need to have any UI.

1. Is it possible to install 2 seperate applications / processes from
one APK?
2. What is the best way ?Should B be a service? How will be the
communication between A and B ?
3. Is it possible to run/call B from A?

Pls. advice

Re: [android-developers] Re: Avoiding GPL

2010-06-24 Thread Andy Savage

I forgot to say in my previous post.

In response to the person talking about MySQL. I believe this is quite
different as MySQL is a completely self contained database system that other
applications communicate with. As in, it's a completely GPL package, rather
than a part of another application.

If you actually incorporated the MySQL code within your application I
believe it would break GPL (presuming your application was closed source). I
am not sure how this applies to the MySQL libraries that are setup to use
mysql say from PHP.

So in the same spirit if the original author decide to create two
self-contained applications that talked to each other and one could view
the source code of one (and have a working application) then I think it
would be fine. I think having a seperate process as such or even a linked
(non-system) library would be breaking GPL. The author might want to
consider this approach :-) although it would be interesting to see
technically how well it works due to speed etc etc.

I do think that there needs to be clearer information about how closed
source projects can use and contribute to open-source under the various
licences.

 Ignoring the legal ramifications here. Let me say my opinion.

 I think that we need to be quite wary of the licences of each app and
 whether they are conforming to it. Obviously this person intends to try and
 not conform to it (if they can figure out how).

 But let me give you an example of why this in general is a bad idea.

 I have gone through some trouble to try and find a way to play DivX/xVid on
 Android for my app and I think that much of my time and trouble wouldn't
 have been wasted if people were more strongly conforming to the software
 that licences are released under.

 Take RockPlayerBase for example, this app (which is in beta) plays DivX
 and xVid. It's not magic, it simply does this by ffmpeg (I can tell by
 checking the library names in the pcakge). I have no website (in English
 atleast) to request this, but when it gets released I will be requesting
 they they conform to the LGPL source and release instructions on how they
 compiled it for android and the changes (if any) they made.

 Whats really frustrating is that they didn't release these instructions at
 the same time as their app. Now this is just one example but I am sure other

Re: [android-developers] Transmitting signals at 433Mhz

2010-06-23 Thread Andy Savage

You would probably need to have a custom radio receiver and appropriate
driver, compile your own custom Android version and have an unlocked device
to load it in to would be my guess.

Perhaps a USB device to do such a job might be appropriate? You could use
the Google Development Phone 2 to do this if you loaded on 2.2 and used the
USB on the Go stuff to actually allow the phone to act as a host.

If you didn't have a USB device, you could use a Serial device and make your
phone talk to it. That would be my recommended path.

I'm sure it's possible, but surely not easy. Both of these options require a
custom device that can transmit/receieve at 433mhz

2010-06-22 Thread Andy Savage

From an Adsense point of view I can understand why this might be a bad idea.

I guess the way the adsense system works is the people who click are the
ones who are genuinally interested. Therefore if you promote people to just
click for no reason other than to support you then the advertiser would be
charged for a click that is very unlikely to lead to a sale.

Distorting the click-to-conversation type ratio.

Specifically for your case hzakimoto, if you want to encourage people to
help support you. I guess the best approach would be to place an obvious
Donate button and ask people to support you that way.

Re: [android-developers] Re: Playing live stream (RTP) in MediaPlayer

2010-06-21 Thread Andy Savage

*Hi Everyone,*

This problem is *really* bugging me. It's a lot bigger than a few of us not
being able to receive RTP.

It's the fact that Android currently *does not support incoming real time
streaming*! This is a *huge* problem for a new platform that wants to really
become the device people buy. Real time video streaming is a huge
industry... what a big oversight??!! I've posted a bug
reporthttp://code.google.com/p/android/issues/detail?id=8959q=rtpcolspec=ID%20Type%20Status%20Owner%20Summary%20Stars
but
I don't expect it to get fixed anytime soon as nobody has posted any
comments or even starred it.

However, there is an upside many people say that the beauty about
open-source is that you can fix it yourself. Sadly I'm not a C-coder and
would spend months just learning it. So, is anybody able to help me with the
required patches to OpenCore? I am sure for somebody with some experience
then it shouldn't be a big deal (I see that RTP is supported using RTSP so
to pass in a native RTP stream or to support SDP's from SIP shouldn't be too
hard I guess).

In the meantime I have been working to overcome this problem, I've attempted
a solution running FFMpeg FFServer on the phone itself to stream out RTSP
(no transcoding just streaming).

My plan was to use this to stream to the video to the local MediaPlayer...
Unfortunately the RTSP playing code is very picky on Android. It wouldn't
play the stream. However I have successfully gotten VLC to play the stream
from the phone (although this doesn't help me so much), so I know it works.
I'm a bit stuck on what to try next!

Any ideas would be appreciated.

Kind regards,
Andy Savage

[android-developers] How do the DivX players render the video?

2010-06-21 Thread Andy Savage

Hi there,

Small question. Does anybody know how the current closed-source DivX players
available on the market work in Android? Are there any open-source versions?

I presume that obviously they bypass the built in Android MediaPlayer and
render the frame's directly (after porting a native DivX codec presumbily).

Do you think they would render each bitmap on an OpenGL surface after
decoding the frame?

[android-developers] Saving an encoded video stream with headers

2010-06-15 Thread Andy Savage

Hi All,

Just wondering if there's a way to save a pre-encoded video stream to a file
with headers.

For example I have a video stream encoded in h264. I simply want to save
this to a file and have mediaplayer playback this file. I have the RTP
framework to do this and can save it to a file, but as the file has no
headers, mediaplayer cannot play it back.

Is there a way to use it as a datasource and have mediaplayer record it?

Cheers,
Andy

Hi everyone,

Currently I am developing an application that will stream video using RTP

using
Java (and native) codecs. I can stream out video also from the camera to
a
windows client.

The problem comes from when I want to receive and decode the video on the
android platform. I understand at this stage that Mediaplayer only
supports
RTSP streams. Ironically it does what I need (by getting the SDP
information
from using RTSP SETUP call and using that RTP/UDP information to receive
the
stream). But I can't seem to access this functionality, all it takes as
input is a RTSP url. If you are unfamiliar the difference between RTSP
using
RTP and SIP using RTP. You can read about the differences
herehttp://www.cs.columbia.edu/~hgs/rtsp/faq.html#rtsp_sip
.

What I need to do is take an RTP stream encoded with h.263-1998 and
somehow
pass it to the mediaplayer (or even a lower level api if somebody can
provide an example).

The only way I can think around this is to write another service
to receive the RTP stream and provide an RTSP interface... but this is a
really ugly solution.

I would really appreciate if anybody could offer any help with this.

I think that it's highly possible for a competing App market to make a

possible though for a company who develops one to pre-install it if they
make a deal with HTC for certain models of phones :-)

Perhaps just pick 2 of the latest phones and make a deal with HTC to include
it alongside the google one. Or perhaps HTC could cobrand (HTC store run by
xyz company).

Re: [android-developers] Re: Playing live stream (RTP) in MediaPlayer

2010-06-09 Thread Andy Savage

You simply pass the RTSP url to MediaPlayer (although I think this
functionality was somewhat broken before 2.1 so I can't be certain that it
will work in 1.6-2.0).

You can play it in the same way that you would play a file (but instead of
passing the file descriptor pass the URL as a string).

MediaPlayer could accept just one SDP (i.e. streamer's), but then how

exchange at least supported CODEC information and connection

Maybe I am just not aware of SDP format with two node's information.

Re: [android-developers] Re: Android Apps purchasing from anywhere in the world

2010-05-26 Thread Andy Savage

I believe that the 30% went to the carriers only?

If what you say is true and they take 30% where there is no carrier deal in
place then they have NO excuse (at least from our perspective) not to
implement *good* paid markets everywhere. For every minute that they don't
they are loosing significant revenue.

In my mind the Google Market is key. This is what will really be the iPhone
killer. Get this right and people will consider to move which means big
dollars for Google (directly or indrectly). Right now it's just idle threats
for people who criticize the iPhone, Apple Store and it's many flaws.
There's no better alternative.

I guess this is a slight rave, but to talk a little further on this when I
read a previous thread in regards to Google ignoring petitions. Seems almost
like shooting themselves in the foot. If enough people want something, why
wouldn't they listen to them and implement? Seems like Google has grown so
big and impersonal that it's loosing touch with it's customers (developer
customers that is).

Pity... because eventually they will figure this out. But in the meantime
they will miss significant revenue and fast-mover advantage.

Re: [android-developers] Re: Playing live stream (RTP) in MediaPlayer

2010-05-25 Thread Andy Savage

In the interests of keeping things together here is the
linkhttp://groups.google.com/group/android-developers/browse_thread/thread/f963e8f7ac35b75bfor
my thread I started in the developers thread just a few days ago
related
to this.

I will file a bug request sometime soon unless anybody else can shed any
light (although I don't know if there will be much attention paid to it). It
is more a feature enhancement than a bug I think, but
it's definitely causing me difficulty.

The functionality to decode RTP streams is already built into OpenCore but
unfortunately you can't pass an SDP file to the MediaPlayer (OpenCore
Wrapper) unless it contains an RTSP stream link inside it. This is a bit
dumb really... what's the point in passing an SDP file in that case? but ah.

There seems to be a limitation that means that it will only accept SDP
information with RTP streams inside if it gets them from the RTSP stream
(e.g. it gets this information from SETUP in the RTSP protocal).

Thus far it seems the only solution is to dump the RTP packets to a file
(periodically close the file and write a new one) then periodically open
these files in mediaplayer. A pretty ugly hack really!

Re: [android-developers] Re: RTP stream video decoding

2010-05-25 Thread Andy Savage

Hi there,

I am working through this in a private discussion with another very helpful
user. Essentially it seems that at this stage the only way to get an RTP
stream to work is a couple of hacks:

A) Wrap it as an RTSP stream.
Basically need a client/server architecture, perhaps another little service
running in the background to buffer the RTP data (perhaps write to file?)
and then respond to appropriate RTSP commands.

I havn't tested this but theoretically it should work.

B) Write the data to two files. For example each file contains 1 second of
data. Write file, close file (thus the file gets timing information and lock
is released) open the file with mediaplayer and play. Meanwhile open another
file to write information to that. When mediaplayer finished with file 1,
get it to play file 2. Meanwhile write information to file 1 again. And keep
looping.

This is horribly resource intensive, but should produce an okay video (so I
hear). Although syncing information for this difficult (impossible?).

That's for streaming in. If your looking for information about streaming out
you should see the Sipdroid code VideoCamera.java where they implement a
'write to file', 'open file and stream' method. It produces a jerky but
reasonable video quality.

Jez,

You might want to consider a pure RTSP implementation for what you want.
That should work fine for one way streaming. Android (atleast in 2.1)
handles this fine.

I understand some functionality relating to this was a little broken in
previous versions.

This sounds terribly. I love AdSense in web pages as it is not
annoying but sometimes even useful. But I really hate ads in software.
I wish what you wrote bellow is not true :-(

Hi,

I don't think that this will happen any time soon for you in
Singapore. Google is living on ads and few months ago Google bought
AdMob for 750 million dollars. It it not in their interest to improve
paid apps after they invested so much money in mobile advertising.

Last year Google said that they will give us list of countries that
will get paid apps... but it is more than a year and still almost
nothing. There were some rumors that paid apps will come to Sweden at
the end of Q1 2009, then that it will come in october 2009, then that
it will come in Q1 2010 but nothing. Many people ask questions about
that on so called Help forum for Android Market but nobody from Google
is answering even if some people asked for more than a year.

People that were on Google IO got 100 dollars checks to use with
Adwords/Adsense (friend that was there told me about that). It looks
like that Google prefer adds... I hope that I am wrong.

[android-developers] Re: RTP stream video decoding

2010-05-24 Thread Andy Savage

A little bit of hunting around has found this
threadhttp://www.mail-archive.com/android-developers@googlegroups.com/msg06179.htmlin
which somebody is trying to use a LocalSocket as a FileDescriptor
passed
to MediaPlayer. Unfortunately he doesn't get an answer.

Does anybody have any working code example where a LocalSocket could be used
to pass data to MediaPlayer? It seems like this would solve my problem as I
could pass data from my incoming RTP stream to a localsocket (I think).

Do you think this could work?

 Hi everyone,

 I need a little bit of help from some experts out there.

 Currently I am developing an application that will stream video using RTP

 Java (and native) codecs. I can stream out video also from the camera to a
 windows client.

 The problem comes from when I want to receive and decode the video on the
 android platform. I understand at this stage that Mediaplayer only supports
 RTSP streams. Ironically it does what I need (by getting the SDP information
 from using RTSP SETUP call and using that RTP/UDP information to receive the
 stream). But I can't seem to access this functionality, all it takes as
 input is a RTSP url. If you are unfamiliar the difference between RTSP using
 RTP and SIP using RTP. You can read about the differences 
 herehttp://www.cs.columbia.edu/~hgs/rtsp/faq.html#rtsp_sip
 .

 What I need to do is take an RTP stream encoded with h.263-1998 and somehow
 pass it to the mediaplayer (or even a lower level api if somebody can
 provide an example).

 The only way I can think around this is to write another service
 to receive the RTP stream and provide an RTSP interface... but this is a
 really ugly solution.

 I would really appreciate if anybody could offer any help with this.

 Kind regards,
 Andy Savage

Hi there,

Any answer to this question? It's bugging me too. Jean, can you tell
us what version you are testing this on? Have you tried 2.1?

 Hi dillirao,

 I don't receive onPrepared callback.

 After requesting the live stream through the SDP file (http://
 server_ip/live.sdp) I receive the following callbacks:
 - onBufferingUpdate -- Buffering 100%
 - onErrorCallback -- Command PLAYER_INIT completed with an error or
 info PVMFErrCorrupt

 My file is encoded in MPEG-4 part 2, audio is AAC, file format
 is .mp4, resolution is 320x240. I have a bitrate of 700kbps but bw
 should not be a problem since I'm on Wi-Fi.
 I can stream the same file with a RTSP request from the Darwin server.
 It works smoothly.

 Any idea why the device returns this error ? evn though it can play
 the same stream via RTSP ?

  Plz write a onErrorcallback and see, if you get error callback.

  whats video profile and audio profile you are using.

  use : h263/h264 15fps; 176x144 or 320x240  and use low bit rate , on
  internet ; if lan, bw is not issu
  for audio: use aac/ again try low bit rate encoding;... amr/ is ok...

   I try to play a live stream on my android phone using the MediaPlayer
   object. But I definitely see a black screen. Does anybody have any
   experience with streaming on Android ?

   Here is what I'm doing:
   I broadcast a stream with Darwin streaming server (via
   PlaylistBroadcast) to my Android phone. The stream is sent over RTP to
   the IP of my device (unicast). A .sdp file describes my stream.

   In my app, I try to play the stream with the following code where url
   is rtsp://server_ip/live.sdp

   private void playVideo(String url) {
          try {
                  //media.setEnabled(false);

                  if (player==null) {
                          //System.out.println(create MediaPlayer);
                          player=new MediaPlayer();
                          player.setScreenOnWhilePlaying(true);
                  } else {
                          player.stop();
                          player.reset();
                  }

                  player.setDataSource(url);
                  //holder.setFixedSize(320, 240);
                  player.setDisplay(holder);

                  player.setAudioStreamType(AudioManager.STREAM_MUSIC);
                  player.setOnPreparedListener(this);
                  player.prepareAsync();
                  player.setOnBufferingUpdateListener(this);
                  player.setOnCompletionListener(this);
          } catch (Throwable t) {
                  System.out.println(Exception in media prep:
   +t.toString());
          }
      }

   public void onPrepared(MediaPlayer mp) {
                  //System.out.println(onPrepared);

                  int width=player.getVideoWidth();
                  int height=player.getVideoHeight();

                  if (width!=0  height!=0) {
                           holder.setFixedSize(width, height);
                           player.start();
                  }
   }

   I always have a black screen, buffering remains at 0%.
   I checked that I can play this live stream on VLC and QT on a desktop,
   and it works fine. If I request the same file via a direct RTSP
   request (rtsp://server_IP/myVideo.mp4) the file plays correctly on my
   android phone.

   I also tried to request the .sdp file by an HTTP request (http://
   server_IP/live.sdp) but the result is the same (black screen).

   Does anybody have already succeeded in playing a live stream on an
   android phone ?

   Cheers

Re: [android-developers] Re: RTP stream video decoding

2010-05-24 Thread Andy Savage

Thanks for your suggestion.

I had considered this. The problem with this approach is that it seems that
the MediaPlayer requires anything passed in as a FileDescriptor to be
seekable (this is the same problem that prevents me from substituting
FileDescriptor for LocalSocket). In this case this means that the file would
have to finish recording before it can be played so that the timing headers
are added.

The idea is to have (semi) real-time video so you can see what's going on.
Think video calling... except that it doesn't quite have to be as
responsible for now.

Anybody else have any ideas?

[android-developers] VP8 Video Codec

2010-05-24 Thread Andy Savage

Hi there,

I am wondering if there is any timeframe for VP8 to be included into
Android?

Is it possible for me to build and use it myself using NDK to decode/encode
video?

Kind regards,
