As Jason suggested you can write a simple protocol which finds out about the clients within your wireless LAN. Something like + clients which are interested to be part of the file transfer within your WLAN are listening to the LAN broadcast ip address + sender sends out a request to all clients which are interested in receiving the file + all clients interested are responding back with their IP address + start your file transfer (ftp or http post) using the client IP address (if you have multiple clients you can loop through the list of clients) Note: you could also use the broadcast IP (more efficient) address for the file transfer but then everyone on the wireless LAN could receive the file. -- Roman Baumgaertner Sr. SW Engineer-OSDC ·T· · ·Mobile· stick together The views, opinions and statements in this email are those of the author solely in their individual capacity, and do not necessarily represent those of T-Mobile USA, Inc.

[android-developers] Re: Client server architecture problem (one receiving thread and many activities)
Michal, I could think of to implement a dispatcher mechanism in your thread where you receive the incoming messages. I assume that you know which traffic should be routed to which activity, correct? You could put the incoming message with an destination identifier (identifier for the activity) in an thread safe container which is accessible by the different activities (for example queue record: dest id, message data). After the message is placed on a message queue, contact the corresponding activity that data is in the message queue. The destination activity would loop through the message queue and be able to find the incoming messages based on the destination identifier. -- Roman Baumgaertner Sr. SW Engineer-OSDC ·T· · ·Mobile· stick together The views, opinions and statements in this email are those of the author solely in their individual capacity, and do not necessarily represent those of T-Mobile USA, Inc.

For being able to uninstall an application you need a permission DELETE_PACKAGES which can only be used by the system or by the application having the same signature. This means you won't be able to uninstall third party application if you don't have the corresponding signature. If it is possible to uninstall application as described above, then Android would have a big security hole.

[android-developers] Re: Devices information using Wifi API
If you want to get valid IP address you can try to enumerate over your LAN addresses. If your LAN network has an IP address like 192.168.1.0 you can try to ping192.168.1.1, 192.168.1.2, ... If you get a response back, you know that there is another system which has the IP address assigned. Of course this is not the most efficient mechanism and might not be successful in all cases (clients in the network might not respond to ping) but it's a possibility ... With the usage of some linux commands like netstat you should be able to get also the corresponding MAC addresses of the IP addresses. -- Roman Baumgaertner Sr. SW Engineer-OSDC ·T· · ·Mobile· stick together The views, opinions and statements in this email are those of the author solely in their individual capacity, and do not necessarily represent those of T-Mobile USA, Inc.

[android-developers] Re: State of a phonecall
I feel your pain . The only way to be more precised in reflecting
call states is to look in the framework/platform code and expose this
information to the higher level (framework code changed needed :-( )
The Android Telephony on SDK level has no concept of a Call or
Connection as other existing TAPI implementations which makes it very
difficult to write a good Telephony application on SDK level

Is there a particular reason for this? Are we not allowed to see the

[android-developers] Re: Is network slower when screen is blacked out?
The speed of your data connection has nothing to do whether your screen is on or not. As Marco already said, when your Wifi data connection is idle, it will turn of the Wifi radio. When the phone goes back to active mode Wifi reconnects. In case of cellular you are not in control of your data connection when your data connection is idle, because in such a case you also get disconnected and lose your IP connectivity. You might want to check the download pattern using Wireshark. The latest Wireshark has some pretty cool new features which support analysis of your data traffic. -- Roman Baumgaertner Sr. SW Engineer-OSDC ·T· · ·Mobile· stick together The views, opinions and statements in this email are those of the author solely in their individual capacity, and do not necessarily represent those of T-Mobile USA, Inc.

It seems like I could accomplish this by having my phone connect to these type of networks automatically, but I'm not sure how to go about this either. I am very interested in what everyone has to say. Thanks! -Ryan Berti --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Handling Network Unavailability
Android supports some intents about network connection change. In your onReceive method listen for this network connection changes and check connectivity with NetworkInfo networkInfo = connection.getActiveNetworkInfo(); (at least this works for me when for example the app loses connectivity it tries to reestablish connectivity on Wifi (preferred interface) and then cellular) If you are one cellular your are going to lose data connectivity if you are not using the data interface. You might want to send out some dummy packets to keep cellular connectivity alive (for example doing a ping to a well known address). -- Roman Baumgaertner Sr. SW Engineer-OSDC ·T· · ·Mobile· stick together The views, opinions and statements in this email are those of the author solely in their individual capacity, and do not necessarily represent those of T-Mobile USA, Inc.

[android-developers] Re: Integrating G729 codec in mjsip
SipDroid has right now implemented the G711 on Java level. You can use the current implementation as a guideline for your G729 codec implementation (how to pass the raw audio to the convert API). First you should answer the question whether you want to implement your codec on Java or on native level. Converting raw audio to G711 is pretty straight forward and not as expensive as converting your raw audio to G729 format (find a native implementation at http://www.readytechnology.co.uk/open/ipp-codecs-g729-g723.1/). Be aware of that you can use g729 only for trial purposes.

Have you tried to find out whether any traffic is successfully sent out the the device using tcpdump or wireshark? Also run a tcpdump on your device to see whether you receive any rtsp streaming.

If yes, can you intercept the rtsp stream before passing the stream to the media player (I assume here that tcpdump tells you that you received the stream) 3. what APIs are you using for the rtsp streaming (openCore?) -- Roman Baumgaertner Sr. SW Engineer-OSDC ·T· · ·Mobile· stick together The views, opinions and statements in this email are those of the author solely in their individual capacity, and do not necessarily represent those of T-Mobile USA, Inc.

[android-developers] Re: Peer-to-peer phone application?
Right now there is no real P2P possible on Android using the official SDK APIs. In case of Wifi there is no support of Ad-Hoc. You could try to use a multicast approach where you try first to discover which devices are in the WLAN. Problem with multicast/broadcast on Wifi is that your network performance gets impacted very fast when you add the number of clients in the network. Also the type of traffic in the WLAN influences the throughput. If you think about using a central server then I would not all your setup P2P anymore. -- Roman Baumgaertner Sr. SW Engineer-OSDC ·T· · ·Mobile· stick together The views, opinions and statements in this email are those of the author solely in their individual capacity, and do not necessarily represent those of T-Mobile USA, Inc.

[android-developers] Re: Android as a virtual PBX
Of course you could think of to run your Android device as a server like system, but be aware that in case of cellular you have to deal with NAT. This means all your clients have to know how to reach you. One possibility to deal with this problem would be to use a cloud service and notify the cloud about your new IP address. In general you can easily support data traffic which does not need to be in a session context (no streaming) like browsing. In this cases you always can re-establish a connection.

Currently I'm having something like this:
_iWifi.setOnClickListener(new View.OnClickListener() {

WifiManager wm = (WifiManager)
getSystemService(WIFI_SERVICE);
if (!wm.isWifiEnabled()) {
wm.setWifiEnabled(true);

}
});
Where _iWifi is a button instant (of course...)
Now, the problem is that it tells me there is a Security Exception

I'm sure a firmware key is not needed in this case (unlike my previous

this?
Please help, thank you in advance :D

[android-developers] Re: Can I use android.provider.Telephony?
Using code in the Android source directly instead of the SDK API's is always a risk. Your application might work for only a temporary time. In cases of framework code changes the chances are high that your app breaks.

I would like to know how a call is processed in android. I have been gng thru the code, but nothing seems to be working out. What do you mean with nothings seems to be working out? Please, be more specific. Which code did you look at (TelephonyManager in framework or native code)? From wat I have seen so far, almost everything is done in the form of java applications (please correct me if I am mistaken). What do your mean with everything? For example the audio handling for cellular calls is not handled in the framework code at all, that's why it is very tough to record a call. Then how do the java functions interact with the lower layer C functions, like the RIL (Radio Interface Layer) in C? You can find the communication from Java to the RIL layer in native in frameworks/base/telephony/java/com/android/internal/telephony/gsm/ RIL.java/ Socket communication is used to talk to the native layer. -- Roman Baumgaertner Sr. SW Engineer-OSDC ·T· · ·Mobile· stick together The views, opinions and statements in this email are those of the author solely in their individual capacity, and do not necessarily represent those of T-Mobile USA, Inc.

When you connect the USB cable make sure that you act on the intent ACTION_UMS_CONNECTED when you mount the USB storage. After receiving the event you could tell the desktop application to send/copy files from the desktop to the sdcard of the device. The other way is not supported which means you can not mount any external storage device to your device (as long as you are not changing the framework/platform) behavior (this communication is only half duplex!)

[android-developers] Re: Solution suggestions
I would go for a). Here are my reasons To retrieve your XML data to obtain server information is a fast TCP call. You can store the data in shared preferences. If the server versions are changing frequently within a day, query for the server data more often. I think a data base (option b) might be an overkill if you have only a few version information to handle. Accessing the server information with shared preferences is straight forward. If the information is much more complex and is also handled on server side in DB, you might want to reconsider your evaluation and create a DB within your main app. In general a separate application which you have to manage adds complexity. You have to think about the following - how do you manage installation/uninstallation of your application? - when is the main application usable (when the second app is installed and has updated server information)? - is it required for your application to have always updated server information? - when a user manually uninstalls your second application (the app which communicates to the server), what do you do? These are only some basic questions. For sure you will come up with much more questions if you go with option b) or c). -- Roman Baumgaertner Sr. SW Engineer-OSDC ·T· · ·Mobile· stick together The views, opinions and statements in this email are those of the author solely in their individual capacity, and do not necessarily represent those of T-Mobile USA, Inc.

I'm wondering about the best way for android (on a mobile device) to handle the equivalent of a web-app. Let's say a client wants a version of their website (which contains server side capability - database, a framework like struts/spring, ajax calls etc) on a mobile device. How would you go about putting something similar onto an android mobile? What are the options, and the technologies you could use? Would you a) simply make a new front end sitting on the existing web servers, written using a simplified XML which android can display appropriately? So all you had to do was call the appropriate web address to view the android version of the website. Or b) would you write a new app entirely for the device, which had a version of the database loaded into it?

[android-developers] Re: discovery of other computers/devices on WiFi network?
You need to implement a discover mechanism which is not trivial. You have the following options -- using a client/server approach where the server knows about the connected clients. When a client gets Wifi connectivity it would tell the server about its connection information.

[android-developers] Re: Ethernet / IP over USB connection?
You have to solve the USB ip connectivity on your Windows system as well as on Android. On Windows I could think of the following options - get a USB IP support based on Linux. You can run VMWare player or another free Virtual machine on top of Windows. Normally USB connections will be detected correctly on the VM. That's at least my experience when I use VMWare and Parallels on the MAC. - use Cygwin o Windows On Android - you have to port over an open source USB IP library to Android. When you google around you will find many open source projects. The porting might be not trivial because you have to make sure that adb is still supported correctly. -- Roman Baumgaertner Sr. SW Engineer-OSDC ·T· · ·Mobile· stick together The views, opinions and statements in this email are those of the author solely in their individual capacity, and do not necessarily represent those of T-Mobile USA, Inc.

[android-developers] Re: Broadcasting reboot intent
Kacper,
Sorry, I am not Dianne but I still answer :-)
I would not allow this permission for 3rd party applications. Of
course Android informs you about permissions of applications you
install but how may people are installing apps without reading or
understanding what they install. When you give a 3rd party app the
power to reboot the phone, there will be many apps which are misusing
this permission.

Bart, Sorry, my bad. I read your post again and I noticed that I misunderstood it a little bit. My idea here was to start the emulator from your second system over NFS. In this case you would run the emulator on one machine and your Eclipse on the other machine. Of course you wouldn't have the DDMS support in this case which I assume you are looking for. Would the following work for you? -- run on both machines Eclipse -- do on the slow machine your development -- create on the faster machine the same project with using the import option (import over NFS) -- start emulator on faster machine and do your testing Changes on your developer machine are visible on your test machine because you are picking up the project over NFS.

[android-developers] Re: Cannot get PhoneNumber on Real device but code works in Emulator
Your code looks fine to me.
Could you check whether this.telMgr.getLine1Number() returns null ?
Also verify the setting application (go to about phone -- status --
phone number). You should be able to see your phone number.
In cases where you have the radio switched off you cannot read the
phone number from your SIM card or the SIM card is not available at
all.
By the way from which carrier is your SIM card?

[android-developers] Re: What is the best way to backup app database to a file?
Are you right now thinking only to backup your data base on the device
or also somewhere on a remote location (PC, server)?
You could easily do a byte copy of your DB
//open your existing DB
InputStream dbStream = mContext.getAssets().open(yourDBName);
OutputStream backupDbStream = new FileOutputStream(path+name of
your backup DB);
//copy file from your existing DB to your backup DB
byte[] buffer = new byte[1024];
int length;
while ((length = dbStream.read(buffer))0){
backupDbStream.write(buffer, 0, length);
}
If you want to support backing up the DB on a remote system, you could
easily use the same mechanism.

Considering the code for the gtalk app is unavailable, I'm unable to discern this information for myself, and haven't been able to find it anywhere -- I know Google has security concerns, but I'm wondering if there is any API at all for communicating with the google talk application itself, such as setting available/busy or signin/out? A plugin for Locale that would be able to do that would be extremely useful, and trivial for me to write, but the information seems not to be available, as far as I can tell. Does anyone know anything about doing this? Jim --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Take a long time to make call
I have to check out this app :-) ... If you have the source code try to find out how long it actual takes from switching from ringing to connected. I could imagine that the phone does the processing in time but the backend processing might be pretty slow for the case you described. Any ideas how many messages are send between the phone and the backend to support GV? -- Roman Baumgaertner Sr. SW Engineer-OSDC ·T· · ·Mobile· stick together The views, opinions and statements in this email are those of the author solely in their individual capacity, and do not necessarily represent those of T-Mobile USA, Inc.

But I found that it is really slow to make a call when unchecking route all the calls through GV and choose dial out instead of call back. I check the source code and found that he use following code to make a call. Intent intent = new Intent(Intent.ACTION_CALL); intent.setData(Uri.parse(tel:+yourphoneNumber)); activity.startActivity(intent); The problem is, when you use above and the phone number is really long ( google voice number, 2, actually phone number), it took a long time to make the call (40 seconds until it connects). Funny thing is that, if I choose route all the calls through GV, then it connects reall fast (10 seconds). Can any one tell me is there another way to make the call efficiently?

[android-developers] Re: Audio streaming
Yes, it does. You can do something like audioStreamer.startStreaming(”http://web -address/your-audio.mp3″, 1444, 180); -- Roman Baumgaertner Sr. SW Engineer-OSDC ·T· · ·Mobile· stick together The views, opinions and statements in this email are those of the author solely in their individual capacity, and do not necessarily represent those of T-Mobile USA, Inc.

I have a few questions and would appreciate if someone can help me answering them. Does Android SDK 1.5 support audio streaming (MP3 stream for example)? If does what API calls I can use? If doesn't what are the plans for future SDK releases that would support streaming? Are there any suggested work arounds until the streaming is supported (like temp files etc)?

Check out the following pages about smartq5/7. It's a device with bluetooth and Wifi support. Don't ask me how difficult the Android porting would be. http://www.engadget.com/2009/02/12/smartq-5-touchscreen-pmp-mid-promises-wifi-bluetooth?icid=sphere_blogsmith_inpage_engadget http://www.pocketables.net/2009/05/smartq-7-internet-tablet-mid-revealed.html -- Roman Baumgaertner Sr. SW Engineer-OSDC ·T· · ·Mobile· stick together The views, opinions and statements in this email are those of the author solely in their individual capacity, and do not necessarily represent those of T-Mobile USA, Inc.

[android-developers] Re: Is it possible to make pure VOIP for Android?
What is for you pure VOIP? In case of putting a Voip application on Android you have to decide which kind of signaling protocol you want to use -- XMPP -- SIP -- your own signaling As Mark already posted earlier, SipDroid is a pretty good Voip client using SIP signaling. You can create an account on pbxes.org and play around with Voip. Both Wifi and 3G Voip is supported. -- Roman Baumgaertner Sr. SW Engineer-OSDC ·T· · ·Mobile· stick together The views, opinions and statements in this email are those of the author solely in their individual capacity, and do not necessarily represent those of T-Mobile USA, Inc.
