Hello, I know that we can use a concept "Java Package" but I just wanted to know that whether Android has provided a DLL concept where I can my most of the functionality. Is there any concept like DLL on Android OS? Can we develop a DLL for better modularization and other benefits on Android? Thanks and Regards, Prashant. --

You can create libraies in C/C++ and share them with your applications. Look at the NDK to see if that may help. http://developer.android.com/sdk/ndk/index.html -Kitzy >

So the short answer to his original question, whether or not there is a 'DLL concept' in Android, is 'no'. If he really wants to, he can use the NDK as you suggest, but that sounds like a lot of custom work for trying to support a C/C++ paradigm in a Java world, an approach that is likely to offer more pain than profit. Android is based on Java, it is only to be expected that the Java way will be more natural. > >

If you download the NDK and look at the examples, it really isn't that difficult to add a library. In fact, it is recomended to place any mathmatical processes into c/c++ code rather than java to speed up processing. Once you have the c library, you can drop the file into your android lib directory on any of your projects and it will be compiled into you APK. Sincerely, -Kitzy > > >
1. Security model for location privacy
Hello all!
I am curious if the Android platform has a security model for
protecting the privacy of the user's location. If there is, it is not
yet adequate. In my opinion one of the biggest security concerns with
Android regards protecting the privacy of the user's location. Is
anyone with me on this?
An Android user should be able to easily monitor and control which
applications have access to its current location information, and to
know exactly how that information is being used. If there is an
active GPS uplink running through one of my apps, I really want to
know about it!
Currently an Android user can only chose to turn off GPS or disable
location services all together (and has to navigate through a few
settings menus in order to do so), and when GPS is turned on they can
only see when it is being used, but there is no way to see _what_ is
accessing it!
A reasonable security model would allow the user to grant or deny
access to positional information to specific apps. Not only would
this help protect the user's privacy, but it would also help manage
battery resources! For example, Android should expect the user to
allow the camera to geo-tag photos, turning on the GPS temporarily to
grab the position when needed, but there's no way we should expect a
paranoid or power-conscious user to turn on and off his GPS before
tagging a photo. Additionally, the user should know if the app
tagging the photo also tries to post its location to a web server.
Relying on the one-time notification of which privileges are going to
be granted to the the app at application install just simply isn't
enough.
Another example: I have an awesome app (Ecorio) that tracks my trips
and helps me to be mindful of my carbon footprint based on my mode of
transportation. I would normally be thrilled about using this app,
but it is not clear what it is doing with my daily travel logs. It
might be keeping them stored privately on my phone, or it might be
uploading them to Ecorio's server. Android should let the user know
what is going on, and when, and should allow the user to deny specific
privileges to individual apps.
This is a very big security concern! I've already been unpleasantly
surprised when I realized that my first test post - an embarrassing
photo tagged with my exact location - was publicly visible on a map on
the welcome page at wherester.com along with other recent posts. The
Android platform should never allow an app to be so careless with my
privacy.
I'm still insanely e{*filter*}d about the future of Android and open mobile
app development, largely because I am confident that concerns like
these will be solved through the process of open collaboration. But
before people will confidently adopt our location-based apps we need
to be to reassure them that the app isn't doing anything unexpected or
not allowed with its positional information.
Does anyone else share my concerns? Is anyone already doing something
to address them?
