Android :: How To Create Protocol Similar To Gmail In Android?
Sep 24, 2010
I would like to explain me better. In android once you receive an email on gmail you would get notified almost in realtime. How does it work? Thinking about an answer i had 1 idea: Android is connected to a gmail server which does not send anything untill it has new mails This solution , which is the only one i can think about, is a little bit expensive, in term of battery consumption. Do you have further ideas ? If not do you know some opensource server that will accomplish my idea ?

I want to create a customized ListView (or similar) which will behave like a closed (circular) one:
1. scrolling down - after the last item was reached the first begins (.., n-1, n, 1, 2, ..)
2. scrolling upward - after the first item was reached the last begins (.., 2, 1, n, n-1, ..)
It sounds simple conceptually but, apparently, there is no straightforward approach to do this.

I tried out Flyscreen the other day and found its card-based flipping through rss/facebook/twitter/weather to be very fluid and pretty. The trouble is, I don't really want that as my lockscreen (besides which, it doesn't seem to truly lock the screen). Does anyone know of a similar app that creates a widget I can flip through in a similar way on a homescreen?

Is there an application for the GMail app for a "send confirm" similar to that of "call confirm?" The call confirm app prompts you to confirm the selection to call, so I am hoping there is one that prompts you before sending. I keep slipping and hitting send before I have completed my emails.

i want to do the following thing - when a user navigates to a web page, I want to have a link in there that looks like this: <p><a href="myprotocol://blah=42">Click here for fun.</a></p> Then when the user clicks on that from the phone browser, I want it to launch my intent with that full url. In my AndroidManifest.xml file, I have the following info: <activity android:name="com.test.MyActivity" style="@style/ MyStyle"> <!-- custom protocol association --><intent-filter><action android:name="android.intent.action.VIEW"></action> <category android:name="android.intent.category.DEFAULT"></category><category android:name="android.intent. category. BROWSABLE"> </category><data android:scheme="myprotocol"/></intent-filter></activity>When I try this, when I click on the link on the web page from the phone browser, it says -- Web page not available The Web page at myprotocol://blah=42 might be temporarily down or it may have moved permanently to a new web address.

When using Protocol Buffers with Android (running in the Windows VM) I'm noticing that the first time I instantiate a protocol buffer based class Android lags for some time. When I step through it looks like it's spending a lot of time dynamically loading the protocol buffer classes. Is there something I can do to speed up this process? I haven't tested yet on a physical device, so the delay might not be as bad but in the VM it takes about 30 - 45 seconds to load all the classes and get past that first message instantiation. What I did was downloaded the Protocol Buffers source code. Compiled the.java files. Stuffed them into a .jar. Added the .jar as an external library to my Eclipse project. Generated the .java classes from the .proto files. Added the generated .java files to my project. Ran my project. I'm not sure if I'm doing something wrong it terms of how to reference external libraries with an Android project, but 30-45 seconds seems like a very long time to wait on a 2.6GHz machine. Also, I recently learned that android uses Protocol Buffers internally. Will this cause any sort of conflicts with my included .jar that could be the problem? I *think* the namespace is different but I'm not entirely sure. Lastly. Why did Google use Protocol Buffers internally and not make it available to SDK developers. This makes me very sad knowing that it's all right there and I can't use it.

For some reason, my Desire won't access any internet pages this morning. When I select any of my favourites it tries hard, but then flicks to a page that says:ERROR The requested URL could not be retrieved.The following error was encountered while trying to retrieve the URL: www.bbc.co.uk ICAP Protocol error The system returned: [No error]This means that some aspect of the ICAP communication failed.Some possible problems are:The ICAP server is not reachable.An illegal response was received from the ICAP server.I've cleared the cache, cookies and history. I'm with Orange if that helps! I've checked a number of sites. I've tried going via favourites and typing URL directly into the address bar. I use the standard Android browser.

Using the Android SDK, is it possible to play a video stream using the MMS protocol I am streaming video from a PC using windows media. I can use Windows Media Player to play the stream by just inputting the following URL in Windows Media Player mms://192.168.223.194:8081. Is it possible to play the same stream using the Android SDK?

We are designing an internal system that will have a .NET PC base station and many Android mobiles, communicating over WiFi. Can't decide between SOAP or XML-RPC protocol. Primary concerns are maturity, compatibility, and the minimizing of coding/integration, in that order. Which is best?

which protocol Google Talk on Android uses? I know that for the Talk application on Gmail uses the Jabber/XMPP protocol. I need to know what protocol (or if it's the same protocol) that's the protocol being used on port 5228.
The reason being, my organization will open the port to the Android sync and push services but only for that specific protocol (for security purposes obviously).

I need to insert,update,delete events in google calendar using android. I tried using the protocol given at http://code.google.com /apis/calendar/data/2.0/developers_guide_protoc but I was unable to go beyond authenticating the user. I was able to authenticate the user and I extracted the Auth code using:- temp1 = EntityUtils.toString (response. getEntity ()); if(response.getStatusLine().getStatusCode()==200) auth = temp1. substring (temp1. indexOf ("Auth=")+5).trim (); After this I tried inserting an event which did not work. I was getting status code 200 in response and I am not sure even if I did get a proper response, how can I extract the cookie s and gsessionid for my next request. I tried creating a calendar instead and I received the same status code 200. I used the following code:- String messageBody="<entry xmlns= 'http://www. w3.org /2005/Atom'"+ " xmlns: gd='http:// schemas. google.com /g/2005'"+ " xmlns:gCal=' http://schemas.google.com /gCal/2005'>"+" <title type='text'>ABC Project Schedule</title>"+ " <summary type='text'>This calendar Type as otherwise I would get a ClientProtocol Exception (content- length was causing the exception, didn't put content-type since it is already mentioned in the entity not sure where it should be defined). I am sorry that I don't understand the basics correctly.

How does Android provide support for traditional TCP or UDP sockets? Is there a wireless IP protocol using just the cell phone? If so, how does this work? Or, do I need an 802.11 chipset in the handset (assuming this isn't standard)?

I was wondering if there is an app that allows you to name your phone. For example lets say i named my Droid. Optimus Prime And then i could use voice protocol after saying my phone's name For example Optimus Prime please text autobots (contact group), "Autobots Transform and roll out!" After saying its name the phone would automatically know that Autobots is a contact group and that the message i want texted is "Autobots Assemble!" Is there an app like this already? If there isn't it would be a great idea for one.

I am hoping to create my own protocol handler for urls in a webview. I have tried two approaches already. The first was to attempt something similar to the approach defined here to create a customer protocol handler. http://java.sun.com/developer /onlineTraining/ protocol handlers / This works in a command-line Java program if I correctly set the system property java.protocol.handler.pkgs, but it does not work in Android, probably because I cannot figure out where to define this system property. Defining the system property in the code does not work. I assume this is because it needs to be loaded when the application first starts. I have also attempted to use URL.setURLStreamHandlerFactory. This works for creating URL objects within the code, but it does not seem to be associated with the WebView. Any ideas on how to get this working?

I'm trying to implement some basic functionality for Google Spreadsheets,using the protocol specification with requests.The reason i'm doing this because it is for Android, and gdata-java library doesn't really work and the alpha android one doesn't really cut it.I managed to implement authentication, and get for lists, and delete, but for editing updating a row i can't really wrap my mind around it.For example i want to change the contents of a cell here is the specification for the protocol From my understanding of it, i have to send some sort of atom or xml formatted request to the edit URL. I never sent such type of requests. I also found this, which gives a clue on how it should be done (also an unanswered question on a forum), but didn't really managed it.Here is my authentication function if you need it, so you don't implement it again, if you want to try and code it.
/*** Logs in to the Google service using the ClientLogin HttpRequest API and returns an authentication token */ private String getAuthToken() {HttpClient httpclient = new DefaultHttpClient();HttpPost httppost = new HttpPost(CLIENT_LOGIN_ADDRESS);
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
nameValuePairs.add(new BasicNameValuePair("accountType", "GOOGLE"));
nameValuePairs.add(new BasicNameValuePair("Email", "username@gmail.com"));
nameValuePairs.add(new BasicNameValuePair("Passwd", "password"));
nameValuePairs.add(new BasicNameValuePair("service", "wise"));
nameValuePairs.add(new BasicNameValuePair("source", SERVICE_NAME));
try {httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));This currently gives a 400 Bad request.Also I'm trying to achieve this using Apache HttpClient. Does anyone have any idea on how this might be achieved implemented how what request i should send?

I have the sbcglobal account in the email app and then the other 3 in the gmail app. How can I switch between the 3 gmail accounts?? Is there a way that I can create 3 different gmail apps or something?

I'm looking for a protocol to secure a connection between a mobile device and a web service. I want to ensure that only the mobile device can perform actions on the web service and vice versa. Data doesn't need to be encrypted. I know Oauth, but it seems that it's more used to secure connections when you got 3 different entities (Server, Consumer and Auth). Here, the Consumer and the User would be the same person. Is there a simple protocol to do that (without requiring the user to login and then authorize the access token like it is the case for Oauth)? I need to use it on different plateforms, so the protocol needs to be available at least on iPhone and PHP.
