I have a service that will send out notifications with timed tasks. I need this service to run outside the life of the application, but I only need to access the services functions during the lifespan of the app. Is a local service enough or do I need to implement AIDL?

Under what circumstances would using AIDL to define a service interface be the correct decision (rather than just creating an extension to the service class)?
View 2 Replies View RelatedI've created a service that is meant to communicated to an activity using aidl's and callback functions. I got it working just fine with my test activity in the same package. But I was wanting to expose this service to different activities running in a completely different .apk file. Is it possible to accomplish this? What does the separate package need to bind to my service and register the callbacks? Or am I going about this completely wrong and should I try a different method for conveying information back and forth between two packages.
View 3 Replies View RelatedI have created a service which exposes few AIDL defined interfaces. I want to access this Service from an application with different package. I have no clue how to achieve this. I want to see an example on this.
Unfortunately all examples I see has client application in the Service package it self:(
Could you please share some sample/example code on this?
I didn't find a sufficient answer to my problem in any posts, if there already is one, please excuse and point me to it, thanks. I made 2 projects. project 1 hast an activity that binds to a service from project 2 on a button click (all just for testing).
How can I make project 1 know (import) my TestInterface (from TestInterface.aidl out of project 2) for usage in: "TestInterface mService = (TestInterface) TestInterface.Stub.asInterface(service);"
without adding project 2 to the build path, because if I'd have an installed service without the project code, I couldn't do it this way, too...?? I read in one thread that TestInterface.aidl should just be added to project 1, too, but if I do this, in DDMS enforceInterface() complains and seems to just see/use the interface from project 1 and it doesn't work.
2. issue:...............
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.
In the implementation of my remote service's published API, is there a way to identify which client called a given method? For example, is there a way to obtain a unique ID or address of the caller? I already cache an AIDL callback reference to the client, but not sure how I can use this for identification.

I have an app that uses a TabHost. Several of the Tabs share a common HUD. I am using a service to periodically update those values by calling an AIDL function when ready.
However, since several of the Tabs are using the same HUD I would like to abstract that part out.
I thought about having the HUD.xml use a String resource as it's value and then the abstracted class can update the String resource. However, apparently Android can not update String resources programatically.
The only alternative solution I see would be using SharedPreference.
I have concerns accessing a Database everytime the value is refreshed.

View 2 Replies View RelatedI'm brand new to android and developing in general. I'm using android's SDK with eclipse Galileo. I've followed several tutorials to create different layouts. I've even learned recently how to use radio buttons and verify which ones were selected. Now I need to create a service that downloads and updates an xml file within the application. I've tried to locate a simple tutorial for services on Google's developer site but so far, so bad. If they exist could somebody point me in the right direction?
On the other hand, I've been told Google's tutorials are a little out dated. Is that true? If so, are there any other tutorials that would hand-hold (and possibly over-explain) how to use a service to a true newbie for free (like google)?

View 2 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.

View 5 Replies View RelatedI have a service that polls for data. To indicate this to the user I have a persistent notification in the statusbar. In some cases when the device goes low on memory it destroys the service but OnDestroy is not called. Later when there is available memory OnCreate is called. Is this normal behavior? I had hoped that OnDestroy would be called to I could remove the notification in the statusbar. Now the user thinks that the service is still running, while it has been stopped by the OS.
In order to restart the polling how do I know that the OnCreate is really a restart event and not first time creation of the service? I thought about checking for the presence of the notification in the statusbar, but I couldn't find a API to check if a notification was showing or not. I have not tried "SetForeground" on the service, since the service isn't that important to the user, but maybe that would minimize the problem.
I have to handle "power down" event in my service, but so far I couldn't find how to receive "power down" event...Do I need to implement "broadcast receiver" functionality in my service? I would appreciate some pointers.
View 2 Replies View RelatedI'm pretty new to Android and Java, though I've really been excited about what I've learned so far. I'm a little uncertain though on how to implement the Model layer.I come from a background in PHP web applications with Zend Framework and the like. I'm used to having an ORM component, through which the Model maps to a database. I haven't really seen anything like this yet for Android, although it's possible I've just not looked hard enough.Are there any good tutorials, articles, 3rd party libraries, etc. that specifically address setting up your Model layer for Android apps?
View 3 Replies View Relatedlike many of you I updated to 2.0.1 with promises of better battery life. After one full day of use I can see now that my battery life isn't improved as much as the phone allocates battery usage stats to different areas other than display. Yesterday my battery actually died BEFORE it usually does (this is post update mind you) and the usage stats told me that I used it mostly on Phone signal (keeping my phone service active when im in the subway). So it said to turn off the phone signal when you're in an area that can't get a signal to save battery life. Well..sounds like a plan, right? What about for those of us that use a bluetooth headset for music? I can't turn off my phone service without also turning off my bluetooth via "Airplane Mode." Does anyone know of a way to turn one off without the other. My motorola Q could do it...please tell me my big bad droid can do it too...
View 2 Replies View RelatedI have tried to figure out a way of exposing(sharing) data between a master application and slave application in a secure way (not world readable), but couldn't find clues on how to do that practically. Of course, reading articles outline that ContentProviders are for sharing persistent data, but I can't find a working example, nor the information how to setup/implement two working piece of software that can work together as different apps.The data I share is simple - ID & Data.If there's anyone that already achieved this already,

It would be great if I could use TabHost, but I believe it doesn't allow this level of customization.
Recently, I installed FRG01B. I had no problems with it except for the fact that I couldn't get the phone to mute.
I noticed that there was a really cool version of FRG22 out by Liquid Frozen Yogurt 1.3 (FRG22).
I downloaded RSD Lite, SPRecovery_ESE81.sbf, and I downloaded the 64 bit drivers for the Droid. I am using Windows 7 Ultimate Edition 64bit. I got the files from this page: FRG01B.SBF for Droid courtesy of RootzWiki - Droid Releases - AllDroid Public Board - FRG01B.SBF for Droid courtesy of RootzWiki - Droid Releases - AllDroid Public Board - AllDroid.org > Home
Anyway, I installed RSD Lite and the drivers. I opened RSD Lite and opened the SPRecovery_ESE81.sbf file. I clicked show device, but nothing was showing up in the window, but below it said connected. I clicked START. After my phone rebooted, it's shot. No service, no battery life, and it keeps rebooting itself. What can I do! Someone please help! My Gmail address is chim777@gmail.com and I will be available for chat as well. I will keep checking this thread every few minutes. Someone please help as I have no clue what the hell I did. All I wanted to do was root my phone.
I had a moment in the beginning and took it back,got a hero had massive problems and finally got my hero replaced with another moment that was brand new.I just got it like 2-3 days ago and its having the same issues that i had on 1.5 when i had it the first time.I had it replaced when i had it the first time and same issue.I have 2.1 now and the battery life is still horrible like dropping not long after taking it off the charger without using it but biggest problem is that the phone will tell me i have no service and it will have an x up above where the bars should be and i have to remove the battery and put it back in before it will work again.The data does the same thing and i can turn the phone off and back on for that and it will work again.Does this happen to anyone else??Its very frustrating!!Also the wifi wont connect.It just says it is unable to connect but it was just working and my laptop works wirelessly so i know that its not my router or anything with my connection.

I'm going on a hike this weekend and thought it'd be a good time to test out either Google Tracks or CardioTrainer to see elevation gain, time, speed, etc. The hike should last about 4 hours. How will my battery hold up with the GPS on the whole time? Assuming these apps have the GPS constantly draining the battery, which I imagine they do.
