Android :: Best Way To Implement RPC Layer To Communicate With Server

May 25, 2009

I'm starting my first Android Application and I'm trying to figure out the best way to implement an RPC layer to communicate with my Tomcat server. Basically, I've got POJOs on the Android Client and on the Server. I simply would like to seserialize the POJOs on Android, send up an HTTP Post, deserialize on the server, do some work, then serialize a POJO response back down to the client. I've seen a number of posts referencing JSON and XML but nothing really definitive.

Further clouding the matter is the different Android SDKs out there that seem to have different levels of support for each. Obviously, if Android has a native library that works well, I'd like to use that. Additionally, I'd like something that could work with my existing POJOs without a great deal of trouble. What are the best practices for this sort of thing? Can anyone send me to any tutorials that have some solid examples on how to get this implemented and going?

HTC Hero :: Connectivity To Google Server

Nov 20, 2010

I have recently created a new gmail account, and transferred all contacts etc. Since my Hero cannot read more than one account, I deleted my first account - planning to reconnect my Hero to the new account - thus enabling all the new data to connect.

However, my phone will not connect to the google server - thus I cannot get my contacts or calendar, and cannot get to the market. The message I get says: 'cannot establish a reliable data connection to the server'.

HTC EVO 4G :: New Evo Wi-fi Won't Communicate

Oct 12, 2010

I'm pretty naive about wi-fi, as I haven't used it much, and I don't have wifi at home, so please forgive if this is a noob question.I got my brand spanking new Evo yesterday (woohoo!). Everything so far seems to work fine, except that I can't get wifi to communicate, although it looks like it's connected. My workplace has an open wifi hotspot (I work in a public library). It looks like the wifi is connected, but when I try any apps, no data seems to go through. They either report no connection, or simply nothing happens.When I look at wifi settings, it shows "connected", an IP address, speed, good connection, etc., but still nothing happens. At lunch, I found three open hotspots within a couple of blocks of here, with the same result, wifi settings shows a good connection, but no data. I tried a bunch of web searches, but nothing I've found seems to address this issue.

When creating a BaseAdapter you attach it to the View with.So the ListView then knows it's adapter to get list elements. But you never tell the BaseAdapter what ListView it is attached to. So when you call BaseAdapter.notifyDataSetChanged() how does it reach the View to tell it to refresh itself?

Android :: How To Communicate From Javascript Back To An App?

It's simple to have javascript call app methods, but any parameters specified in the call on the javascript side don't survive the trip (I just get null in the app).Gross hacks seem obvious (open a url and encode the data in the url), but that can't be right.You received this message because you are subscribed to the Google Groups "Android Developers" group.

Android :: Communicate Which Button Pressed?

Sep 30, 2009

i have an app widget that has a couple of buttons on it, and in my onUpdate() call, I am hooking up the buttons to do something when you press them

RemoteViews remoteViews = new RemoteViews(context.getPackageName (), R.layout.appwidget);                 remoteViews.setOnClickPendingIntent(R.id.Button1, button1PendingIntent);                 remoteViews.setOnClickPendingIntent(R.id.Button2, button2PendingIntent);

The problem is that when I click on button2, it sends the button1 pending intent. i think that's because it's reusing the pending intent. http://groups.google.com/group/android-developers/browse_thread/threa. "If the creating application later re-retrieves the same kind of PendingIntent (same operation, same Intent action, data, categories, and components, and same flags), it will receive a PendingIntent representing the same token if that is still valid, and can thus call cancel() to remove it." So then the question is, how do I communicate which button was pressed?

Android :: Getting Service To Communicate With Activity?

Jun 25, 2010

I currently have a Service and an Activity in my application.I currently bind the Service to the activity without using AIDL as the Service and the Activity are in the same application.This allows me to call the methods from the Service within my Activity when I require them, however it doesn't let me call the methods of the Activity from within my Service when I want to.Can anyone comment on what would be the best way to achieve this?I could use Intents but is there an alternative option?I want to have tight communication between the Service and the Activity, I want to be able to call an Activity method from my Service when an event happens.

I now have it working the way I want, however I have come across a problem.My service gets status updates and my Activity is then supposed to react to the update sent on from the Service.The problem is that when I start my activity I get the Dialling Status and then Connected status before the onBind is called and I get the instance of iCallDialogActivity.

I need to be able to use my iCallDialogActivity when I get the Dialling and Connected Status notifications.But this gives me a NullPointer Exception due to it not being created in time when my Activity starts, binding is the first thing I do in my Activities onCreate().Is there a way to make it bind straight away?

Android :: Communicate Progress From Local Service

May 16, 2010

An application I'm building uses a local Service for downloading files from the web to the phone's SD card. In this app users can browse lists of books, and read them while online. A user can also download a pdf copy of a book for offline viewing. To handle downloads I'm using a locally bound Service. I do not want this Service to run all the time, only when downloading files. So that the Service can shut itself down when its tasks are complete, I am not binding to the service, rather I'm sending an "enqueue for download" command through the Intent passed to Context.startService.

Books available for download are shown in a list. A user can choose to download a book by clicking on its row in the list. On download, I need to show download progress using a ProgressBar on the actual book list row. I need to also show, on the rows, if a book is enqueued for download, or if its download has completed or failed. The books can be shown in different activities throughout the application--in search, or in the user's list of favorite books, for example. When the books are shown in different places, these are not the same objects, but they are uniquely identified by their bookId...............

Android :: Best Way For Service That Starts Activity To Communicate With It

Feb 16, 2010

I have a service that listens to a socket. When receiving certain input it is to create an activity. When receiving other input, it is to kill this activity. I have struggled for a while to make the service communicate with the activity through AIDL (http://developer.android.com/guide/developing/tools/aidl.html), but this seems to not be effective. I think AIDL is only effective when the process that is to be talked to is a service, not when it is an activity? I would love some directions or suggestions on how to solve my problem.

Android :: How To Make Java And C Programs Communicate Together?

Is this correct? Is it a bad way of doing it? Is there a better way?

Android :: Wi-Fi Connectivity With 1.6

Oct 28, 2009

My application has some code which detects if the Android device is connected to a Wi-Fi or Mobile network.

The code appeared to be working fine for Andoid 1.5, but does not seem to work correctly for Andorid 1.6.

Here is the code I am using:

CODE:..........................

Under Android 1.5 this code would correctly detect if the current connectivity was Wi-Fi or Mobile.  However under Android 1.6 the call to getActiveNetworkInfo seems to always return a networkInfo instance with the type set to TYPE_MOBILE.  This is happening even though the icons in the bar at the top of the android screen show the Wi-Fi connected icon with the full signal strength bars showing.

I don't know if this means that under Android 1.6 it is actually using the phone data network for connectivity instead of the Wi-Fi connectivity when both networks are available, or if the getActiveNetworkInfo call is just returning the wrong information for Android 1.6.

Has anyone else seen this issue with Andoid 1.6?  It would be too bad if 1.6 is really using the bandwidth on the phone data network instead of the Wi-Fi network when both networks are present. Does anyone know if there is a different way to correctly detect if the Android device has Wi-Fi connectivity?

Android :: Connectivity On H In Status Bar / Now On G Or 3G

Apr 29, 2010

I am with first Droid phone. I have had an HTC Desire for approximately 1 week and absolutely love it. When I first got the phone, the connectivity was always H in the status bar, with very good I-net speed. For some reason, unbeknown to me, it is now a G, sometimes a 3G. The speed is still quite good though. This 'change' would appear to have been since I received a text from T-Mobile (I'm aware of the 'G' issues on their forums) alongwith the lines. They hoped I liked their new webpage. Now they have reverted to the original webpage I may have to re-load my favorites. I have not had to do this, thankfully. Under Wireless & Networks, WiFi is off, as I am on an 'unlimited' 3GB plan, and I am using GSM/WCDMA auto under Preferred network mode.

Questions: -
1. What is the difference between the three, namely H, 3G and G?
2. Which is quicker?
2. Can I change it back to H, if I wanted, as I believe it was quicker?
4. Sometimes, although not very often, the G, 3G and H disappear altogether and I am left with no connectivity at all. However, if I try to access the I-net, I can, and either the G, 3G or H appear again miraculously. Is there a particular reason for this?
Hope to hear from you experts soon and apologies for such basic questions, as I'm still getting used to using a droid. My last phone was a Nokia N95 2GB. Huge difference!

Does anyone have a clue how to resolve this or is it a defect with the phone.Some details: there is no 3G symbol near the signal status bars.Settings/Wireless & networks: shows "Mobile Network" with a green check, buts its grayed out so no action can be taken on it.Directly underneath "Mobile Network" it says "Turning on..." and it seems to flash that status every once in a while.

All web pages load with the standard "web page not available" and apps, eg. the market place, won't connect either.
