Is there any build-in mechanism in Android, which could create a service or app that actually listens to some server from the out side.. something that will "Wake up" the phone and makes him receiving a message from an outside server (i am asking this coz most of the appz are working the way around, when the phone sending requests to an outside server to receive data)
is it possible any how?

Is it possible to register a listener to listen for changes in the volume level of the music stream in Android?
I'm displaying the actual volume in a SeekBar and I would like to change the seekbar if the user changes the volume with the hardware volume keys. At the moment the correct volume is displayed until the user changes the volume with hardware keys.
In current activity, when user click the back key, I don't what it back to the last activity. Can I add a listener to listen to back key in current activity? When user click "back" key, it actually back to the activity I want it to go.

problem: server (web server) wants to send data( or some information) to mobile client (android based phone). means simply notify to start work, then mobile start working on specific application. i would like to do a SMS from server to mobile, to start working. buts its not the best idea. as we can assign too an IP to android mobile phone in case of WiFi or USB connectivity. but phone will use GPRS or GSM, so there is no unique IP of Mobile so that we can access mobile phone using Socket Programing.
View 2 Replies View RelatedWe are designing a system with a PC base station and 100 Android mobiles communicating over WiFi. They will use XLM-RPC as the method of mobile to base station communication. However, sometimes the base station needs to broadcast a message to all mobiles. Should we use "http server push" for this, i.e., have the base station leave the connections open to all the mobiles? Is there a better way? Publish-subscribe is possible, but doesn't seem mature on Android yet.
View 1 Replies View RelatedI have recently written a socket server in PHP that will be handling communication between an Android phone application and my PHP webserver. Due to the fact that Android doesn't natively support push style notifications we are going to be using our webserver as the middleware layer to handle our 'pushes'. The socket server is stable, runs well, and seems to scale nicely. While I would eventually like to re-write this in C I don't have the skill necessary to do that right now so I am going to be staying in PHP for at least a short while. As of this moment our Android emulator is able to communicate through the server, get pushes, etc. so that part is all covered.
My concern is that, right now, anyone can open a socket to my server and will be given a client connection. While we won't be passing sensitive data back and forth I don't want to allow just anyone to connect over and receive broadcast information, eat up my resources, and clog my server in general. The question is, how do I secure a server like this? Let's assume that I am running on port 25,000--can I set up some sort of SSL layer on that port and expect devices like the Android to be able to communicate over that port without any special protocols or jumping through hoops? I have considered asking the connecting clients to authenticate their user against our user database before being given a client connection, but that would require the passing of credentials in plain text over the network which I am not about to do.
I am rather new to straight TCP communication from PHP and feel like I might just be missing something simple that allows for authentication on this level.
Additional information: If I am able to get a valid username and password securely I would be using MySQL to validate the user and then accept/reject their connection based on the results of the query.
I understand that HTC Sync will allow for syncing with an exchange server (not just desktop client software). Can anyone confirm that it supports push email and not just periodic checking?
View 7 Replies View RelatedI'm just wondering if I'm able to create a View from an external XML source. As I was reading, you must place the XML layout inside the res/layout and when you compile it, you can load the layout by typing setContentView(R.layouts.my_layout). What if I have this XML layout online (on a website) and I want to create the layout on runtime? Is there any way to do this? Or I have to parse the XML and create the layout (hard-coded)?

View 2 Replies View RelatedI'm working on a litte HTTP server application for the Android. Now I like to secure the communication by using SSL. But I got stuck by creating a suitable keystore file. Searching the archives I came to the conclusion that it will be best to use a BKS type keystore since all other keystore types (like JKS) are not supported on the android.
Unfortunately I can't figure out a way to setup the keystore file. I tried OpenSSL - wrong keystore format. I tried the keytool from JDK - right keystore format but it doesn't support BKS keystores. I tried the Keytool IUI - I could create a BKS type keystore but it alwais ends up in an InvalidKeyException "Illegal key size". No matter if I try to create a new certificate or import it from a JKS keystore. (I tried to create the RSA ver.3 certificate with a key size of 2048 and 1024 bits.) How do you create BKS keystores?
For completeness here's the code I trying to use for loading the keystore:..............................
I'm looking at 3 different apps to develop for the Android, but I'm new to the platform (come over from Blackberry - yuck!).
Anyhow - I need to know if there is some way to push data to the phone from a server. I'd prefer to avoid using SMS to push (user charges), or constantly polling the server (lets see, every 5 seconds = 12 times a minute, 720 times an hour, over 17000 a day)

View 9 Replies View RelatedI have a strange problem with Push email on my HTC Desire. I can set this up no problem - email comes in but only manually. I cannot get the push to actually work. When I go into the send receive schedule I can set up the days/hours for peak off peak and push but regardless of what I set these to be, when I go back to the previous screen it always says the Schedule is Manual. I've tried setting up lots of variations from manual through timed to push but still the same. Net result is push never seems to happen - manual overrides my schedule. To pick up email I have to go into email and do a manual sync.
