I followed the instructions here on how to create an Android library project, and use it in an Android application:
http://developer.android.com/guide/developing/eclipse-adt.html
But it is not working. I can see the library project is added to my application but I cannot reference anything in it because it won't build. The R.java file from the lib is NOT being added to my application project, so the lib project contains tons of errors, everywhere it tries to reference it's own R.java file.
I don't know if this has anything to do with it, but in the console there are messages stating that the there is "No resource identifier found for attribute 'X' in package 'Lib Package'. My library package has a a few styleable attributes defined for a custom view I made, all of which are being complained about in this console message. The library builds just fine, and I don't get those messages in the console until I hook the library to my application, so I don't know what's up with this.
How do I start a project wherein I can design an application which fetches weather forecasts from existing web sites?

I have created the Client-Server application. At the Server site i have used the AIDL to impliment the interfaces in my Service class. At Client site i have exposed the AIDL interfaces and have one Activity that mainly do the IPC mechanism , i mean ServiceConnection, bindService and then call the Serivce of the Client site. But i am getting the error i mentioned during the bindService call.
Could you please let me know the steps mainly i have to follow to run the Client -Server Application. For time being i am running the Client .apk first and then the Server .apk, but the server one giving me error.
It would be great if you could let me know what all permission short of thing to take care, as my Client and Server code are placed at different APks, so do i need to import the Client project in my Server Project, if yes then how to impliment that.
I've been trying to do this now for 2 whole days, and am about to give up. I followed the instructions here:

Also the R.java file from the lib was NOT added to my application, so the lib project contains tons of errors, everywhere it tries to reference it's own R.java file (most likely the cause of the former).

You would think that creating and referencing a library would be a simple thing to do, as it is in most other projects, but this is turning into a real nightmare.
I'm trying to set up an Android application with an Android library project dependence in Eclipse. I've set up a project called AnTest and a library project called AnLib. I've provided a reference to AnLib in the project properties of AnTest. Now I'm trying to refer to some library code (a static public method) from AnTest. Eclipse throws "com.anlib.Hello cannot be resolved to a type".
And it's not that the reference is dangling - I can see the resources properly merged. But from within AnTest, the only class in package com.anlib is "R".I've added AnLib to the Java build path/Projects in AnTest project properties. Now it compiles, but running throws a NoClassDefFoundError exception.
Somethings I'll have an? .xml file selected when I compile a project, only to have a? .out.xml generated. Deleting the file doesn't clear the error, and Eclipse won't compile the project. It just reports that your project contains errors. The solution is to go to Project/Clean. This will clear the error in the project and allow it to compile.

I have 2 android projects out of which I modified one to work as a library. I want the main project to refer to this library to perform few functions. While this scenario works just as expected, I want to introduce one more functionality. I want to link this library project with another just a java project which has code common to both Android and Blackberry applications. This second part however doesn't seem to work and throws "The application <appname> (<package name>) has stopped unexpectedly. Please try again" with a ForceClose button. I would greatly appreciate if someone can give a brief information on how to make this work.

View 2 Replies View RelatedI'm writing an app that needs one or more applications/services that are distributed with their own seperate apk file. I'm writing a user-app that allows the user to upload pics using a service. The service can be used by multiple user-apps, not just mine. I'd like to have the service being installed in its own apk, instead of bundling it with each user-app. Has anyone had experience with this scenario? What is the best scenario i should implement so that the user downloads the service that the user-app needs? Can be this be done automatically (that would be best)? If not, in your opinion, what would be the most user-friendly way for doing so?
View 4 Replies View RelatedIf an application begins a Service via bindService or startService, will this Service object ever run from a process different from that of the application? I ask because many Android example projects begin a service and communicate to them using IPC which seems wholly unnecessary considering that, according to the Android Service documentation, "... services, like other application objects, run in the main thread of their hosting process." IPC, AIDL, and the IBinder interface only seem useful if connecting to a Service started by an application other than your own. Is this a correct or fair understanding?
View 1 Replies View RelatedIs it possible implement an Android application as a web service? On the official site I've read:
Note: If you want to develop a server-side application, we recommend that you implement your application as a servlet running in a servlet engine like Tomcat or full-blown JSEE container like Geronimo. If you prefer to implement a server-side application based on our HttpService, we'll assume that you know what you're doing and that you don't need help in figuring out which interceptors need to be configured.

I have data that is to be refreshed from the Internet. Let's call it Model.
What I want to do: Basically it sounds like an MVC model, where the Model is also kept persistent in local (private) storage. The Model and its associated methods are application-wise. There are several Activity's that display and manipulate different aspects of it:
User
navigates across different Activity's
that display Model
from different perspectives. Currently I have a ListActivity for all elements, and an Activity for one element's details
Sometimes Model needs refreshing.
Surely this is done on a different thread. Refreshing can be triggered from several Activity's.
There are several (time consuming) common
tasks that can be triggered from different Activity's
My application loads and saves Model
to private storage when it starts
and stops
My problem: I'm not sure where to put Model and the related tasks in. Also, I don't know what mechanism to use to notify Activity's. Currently I come up with 2 approaches:
Use Service and send broadcasts. Saving to disk is performed in Service#onDestroyed(), so I want to minimize that by binding it to Activity's. At this point, I'm also not sure how to deliver the updated information: whether to provide a getter in Binder, or include that in the broadcast message.
Customize the Application object so that refreshing methods and getters are available globally. I then perform update from Activity's using AsyncTask. If there are other Activity's that are behind the current Activity, they will update in onResume() when the user navigates back.
Reasons I'm not using a class with static methods:
I need to save and store Model to disk. Some of the methods need a Context for displaying toasts, notifications, caching, etc.
Also, I don't put these functionalities in an Activity because there are several activities that manipulate the same piece of persistent data.
Below are pseudocode illustrating what I mean:
Using Service:
CODE:............
Make the functionality globally accessible in the custom Application object
CODE:...........
Weaknesses I can think of for the Service approach is complexity, since Binding is asynchronous. And it's very likely that I have to repeat some code because I have both ListActivity and Activity
For the Application approach, the documentation says not to rely on onTerminate() being called.

3) PhoneBlock extends Activity

I have created a service and want to expose the interface to other applications. For one service I have done this successfuly. I just put the AIDL interface into the new project and all worked fine. Now for this service I've done the same but I get a java.lang.VerifyError when trying to use this interface. I think that the problem is that the AIDL uses a class (PolicyRole) that is only defined in the source code of the service. To compile the source that uses the interface I had to link against the code of the service but at runtime the error appears. Code...

View 1 Replies View RelatedI am trying to create a Servicefor my application which will negotiate Bluetooth connections and data. I want this service's lifecycle to start and end with the Application, but still be able to have specific Activities listen for events that occur within this service (in addition an Activty should be able to call specific methods of the Service to write data or query connection state).
I started by creating AIDL interfaces for my callbacks and service, but I can't figure out exactly what I'm doing.
How is the best way to go about this? EDIT: To be clear, I do not specifically need (or want) more than one process for my application. Right now I don't have more than one; I'm just using AIDL because it is the only way I know of for a Service to communicate with an Activity.
I have a local Service running together with my application. I also have a class derrived from Application class.
When the local service is created it gets and uses the Application instance using getApplication.
Can the app itself be terminated while my service is still running and what happens if so? Would getApplication return null?
