I know about LocationManagerService, AlarmManagerService, and BatteryService, from Android programming books, but is there a published list of all available services?

I'm developing on an application at the moment which contains quite a lot of personal user information - things like Facebook contacts, etc ... Now, one of the things I want to be able to do (and have done, quite effectively) is open up parts of the application to "3rd Party" applications, using Android's build-in inter-process communication protocol (AIDL). So far so good.Here's the catch: because we're involved in handling quite a lot of personal information, we have to be quite careful about who can and can't access it; specifically, only "Trusted" applications should be able to do so. So the natural way to do this is to use a custom permission within the AndroidManifest.xml file where we declare the services. My problem is this: I want to be able to enact signature-level protection (similar to the normal "signature" permission level), but with a bit of a catch:
I don't only want application signed with our internal signature to be able to access the services. I'd like to be able to build a list of "trusted signatures" & at runtime (or if there's a better way, then maybe some other time?) be able to check incoming requests against this list of trusted keys.This would satisfy the security constraints in the same way as the normal "signature" permission level I think - only programs on the "trusted keys list" would be able to access the services, and keys are hard to spoof (if possible at all?) - but with the added bonus that we wouldn't have to sign every application making use of the APIs with our internal team's key.Is this possible at the moment in Android? And if so, are there any special requirements?
I'm having trouble developing an app, while it works in API level 10, it does not in API level 7. I wondery why and I've been looking for a site that summarizes the differences, or the new features from one API level to another and cannot find it.

There seems to be a problem with an uncaught exception and reflection, although....why does it work on API level 10?

View 1 Replies View RelatedI have updated my tools to revision 7 and now I can't do a build as it says the API level is obsolete. I can understand warning but it won't build at all. I am using android.bat to generate a build.xml for release versions. So the build.xml gets made from scratch each time. If I switch to --target 8 it builds but I have already released it on the Android Market with 6. Won't this mean that some people that have Android 2.0.1 won't be able to run it?
CODE:........
I'm looking for some way in Android to play in-memory audio in a manner analogous to the waveOutOpen family of methods in Windows programming. The waveOut... methods essentially let an application create arrays of sample values (like in-memory WAV files without the headers) and dump them into a queue for sequential playback. Windows transitions seamlessly from one array to the next, so as long as the application keeps dumping arrays into the queue ahead of playback, the program can create and play continuous audio of any arbitrary length. The Windows API also incorporates a callback mechanism that the application can use to indicate progress and load additional buffers.
As far as I can tell, the Android audio API lets an application play a file from local storage or a URL, or from a memory stream. Is there any way to get Android to "queue up" MediaPlayer.start() calls so that one player transitions (without glitches) into the next upon play completion? It appears that Jet does something like this, but only with its own internal synthesis engine. Is there any other way of accessing Android audio in a waveOutOpen way?

View 2 Replies View RelatedIs there a way to trace through function calls at the lowest levels of the Android system? Right now when I debug in Eclipse, it goes through the source files that are located inside the frameworks folder, but is it possible to go even lower? For example show what functions are being called from the libcore folder. I am also interested to find how it communicates with the linux kernel at the bottom of the layers. Is there a way to do this?

I want to make 1 version of an application but only use AnticipateOvershootInterpolator()
to >3 Api level devices.
Google suggests in Dev Guide that we set the API level as low as possible to cover most of the devices. Somebody recently pointed out in my app that when they are typing in the password the automatic suggestions pop up making it annoying. I found out the solution, but is only available in API level 3.I guess my question is, are there devices out there that use Android 1.1 still?

Ideally, we could include these for level 3 and 4 users, and they just won't be shown the contact sync option at all. Is this how it's meant to work?
I'm trying to understand the idea behind the Services. If it runs in the program's thread, why not create just a separate thread (or AsyncTask) to do the job? Can a service keep running in the background? For example, i want to create a task that will continuously be polling data from a server, even if the main application is not running. Can this be achieved with a Service?

View 2 Replies View RelatedIn my ideal little dream world, I'd like to have a custom service running that handles network comms. Activities (e.g. UIs) then add listeners to it and it provides callbacks when anything interesting happens.
As it stands, I can't see how to do this in an appropriate way. OK, you can call bindService() and have a ServiceConnection implementation that monitors the service state. From there you can easily talk *to* the service whenever you desire, using serialisation over transactions, but I don't think that helps with communication initiated by the service.
The only way I know of doing what I want is by maintaining static collections of listeners on the service class, which doesn't strike me as good engineering.
When an app gets permission to access your Google account's Android services exactly what does it have access to? Is it authenticated to access all your google stuff including gmail?
For example, I installed Changelog Droid from the play store and it wants to access my Android services. I understand it probably only needs the permission to access my play store account to analyze my installed apps, but what else is open to it if I give it the permission?
I am quite confused with the user IDs stuff and what they mean in the process level. In Linux, every process uses its own virtual address space and no process can write to the address space of another process. So the communication between two processes is conducted via IPC mechanisms which are part of the Linux kernel. Are two processes with different user IDs allowed to IPC?
