Android :: Service Utilizing Custom Usb Device
Apr 28, 2009
I am looking to implement an Android service that will serve as the "driver/hardware access" for a device that will connect to the usb host port. Is there a good framework or example showing how I can make a service interact with this device? Its not a standard device that Android already supports other than the fact it connects via usb.
I am able to do this with linux libusb native code already but what would be the pathway to make this work through the android java framework?
I want to avoid having to make a kernel level driver for this that is why I prefer to have this implemented as a service for other apps to access the device.

Are we ever going to be able to utilize this storage with anything other than a file browser or the stock apps? One of the larger selling points to this phone was the fact that it had some internal storage. It is useful, pretty fast and it's right there. I was hoping that HTC would get right on this and have an update out, but I've yet to even hear HTC admit that there is even a problem. I don't remember being told that my internal storage would only be available with the apps that came stock on the phone.
I, currently, have decided to keep my music on the internal storage. It frees up my SD card for storing stuff from apps and the like. I've got a couple short videos on the internal, too. I've got just over 2500 songs which weigh in just under 5 gigs, on my phone. I would love to be able to use TuneWiki or something that was a little better about getting and showing album covers, or even have a choice for a better music player and/or widget. I currently can't do that, because nothing seems to read the internal storage. Do we have any word that this is going to change in the near future. I know that we are all excited about the prospect of FroYo, soon, but what about this existing issue.

I have a set of mp3 files on my computer which i want to be the server. Now i have a web service(Songs_Collection). This web service returns the list of all songs present on the server to the user.The user can download the desired file directly from the server.
I have a small problem :
How does my web service get the list of audio files kept on the server in the folder c:Audio Files.
Someone suggested that i need to keep the names in a "Web Content" folder, but can anyone suggest how should i approach it?
I worked out on this part . But now how do I send it to the client on device ?
Can i send it directly as an array? I guess then some seriliazation-deserialization needs to be done. Or If send it as an XML file then how should I proceed? (This is more important)

I have written a class which extends the Service class of android and would like to launch the service during device boot-up. From the service I would like to receive the intents such as boot completed and screen off and on. Currently I am using a BroadcastReceiver to get the boot completed intent and then on starting a service to receive screen on and off intents. But I would like to remove either the broadcast receiver or the service. Any inputs.

I've read the posts that state that there is no way to automatically start a service right after the package is installed. In my case, i have two apps- one runs as a service and collects data, the other displays it. the second app has the Activity which can be used to start the service. in order to provide the most accurate information, the service must be started immediately after installation. however, if the user decides not to run the activity immediately, then there would be a gap between the time the service is installed, versus when it gets started. of course, asking user to reboot after installation is one option, but not a great user experience. Any suggestions on how to achieve this?

I was interested in developing a clock widget for the homescreen and upon reading Home Screen Widgets tutorial, I wondered if there is a pre-existing Service I could reference for updating the current time rather than re-inventing the wheel?I download the Retro Clock application on my android phone and noticed that when I click it, it pops up the Alarm Clock settings, but with the default Google Analog Clock widget, upon click does nothing.Is that because the Retro Clock widget implements the Alarm Clock service? If so, how can I go about referencing that service? Or do I have this all wrong and misunderstood?

I'm currently working on an XMPP app' on Android and I'm pondering about the best way to throw a different type of Exception than a RemoteException to my activity from my service.
As it seems impossible to throw another thing than a RemoteException using IPC (you can't declare to throw anything in your .aidl), I just see two solutions:
Create a listener for my activity to listen on my custom XMPP exception, which in fact will not be thrown but just sent as a usual object implementing the Parcelable protocol.
Catch my XMPPException and throw a RemoteException (with a content updated with my XMPPException) - But in that case, how could I know on my activity if it's an XMPP or a real RemoteException ? By tagging the name of the exception and parsing it on my activity ? It would be really gore.

I just launched my app VLC Remote and was surprised to see that there isn't a way to post a link to the app on the market that works both on my android device and also in my browser.
-so I made a way, and I'm opening it up for all-comers.
What it does is lets you post an http link like this
http://and-download.hobbyistsoftware.com/android/download?name=VLC Remote&q=pname:com.hobbyistsoftware.android.vlcremote
If someone clicks on the link from an android device, then the link opens in the market. If they click from their computer, then it offers to send them a link by email (so they can click on the link on their device).
the download emails have a (subtle) advert for my app, but the feature is clearly your app!
details are here:[url]

I have coded this service, that computes stuff and i want other applications to be able to bind this service, i.e. i want to enable other programmers to communicate with this service. problem is, this has to work without these other programmers to get access to the source code. just the (installed) apk with the remote service is given (and of course a detailed description of the service' interface)...problem is, eclipse keeps braggin' about that the packages of the service are not available in source code...

I have a service that regularly queries a web server for new messages. The service stores the new messages in an arrayList. These messages are implemented using a custom class, storing all kinds of metadata (strings and longs).
An activity then connects to this service to retrieve those messages and display them to the user.
I have an .aidl file that describes the interface that the service exposes.
CODE:..........
The Message class extends the Parcelable class which should allow for the IPC transfer.
The problem is this: Eclipse gives me an error saying that the type of List<Message> is unknown. Any imports are marked as invalid.

I have a background service component which is reacting to changes in network connectivity. I would like to alert the user that a a connectivity change event has occurred by popping up a Toast View on the device screen. Is this possible ? Can it be done even though a Service component does not have a UI associated with it ?

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.

I need test my Android app on a Motorola Cliq but don't have one. Is there a testing service that will let me make a debug connection to that device so I can run some tests and find out where the code is failing. Video connections won't tell me that.

I have a Service that downloads a file from the internet. What I want is for the response (an InputStream in this case) to be handled by a custom handler that can be switched (like a strategy pattern) but I can't figure out how to do this. So basically the User of the API would be able to plug in different handlers for the response, some would parse XML, others might save files etc. I realise I could pass through the activity context and execute the method from this (given some interface) but I don't want to do this obviously, in case the Activity is closed in the meantime while the file is still downloaded.
UPDATE - I just had one idea it will work sort of but has problem if the DownloadRunnable gets changed between executions of the downloads.
The modified Runnable interface
interface DownloadRunnable {
void run(InputStream stream);
}
An enum
public enum ServiceHandler {.......................

Trying the 'Device Self Service 1.1' app to update my PRL (prefered roaming list) before I head out on a trip. I expect the 'udpate firmware' option not to work, but the 'update profile' and 'update prl' do not work. When trying to run either, I get a 'no service' error, even though I have 4 bars.

Tried to access it today and it was saying that i was entering the wrong pin. I know for a fact that it was right. Now i'm locked out of it and it says to call sprint to continue. I talked to them for about 45 minutes, they switched me over to HTC for another 30 and then back to sprint for another hour. They had me hard reset the phone twice and it didn't do anything. Was on the phone with advanced tech for the last hour and they finally said to wait 2 hours and it should reset itself. Well, it's now been about 5 and it still won't work... Any ideas on how to get it to work?
