That's the package name for
Samsung Deskphone Manager. Android apps use a
package name as a unique identifier. Each app must have a unique one so that you don't install one app in or over another. The package name is also part of the app's
URL for the play store. This is yet another reason why an app's package name must be unique. When you install an app, whether it be from the play store, third-party market, or straight from an
APK, an app package is downloaded (or loaded) and then installed from the app's APK. The APK contains the resources and
dalvik code for the app. The package name in the APK becomes the installation directory and will also create a copy of the app's APK within the installation path. An APK is akin to a
Win32 ".exe" executable, but acts as an installation package at the same time. They're essentially a
ZIP archive that houses the app's compiled code/resources that are used when the app is launched. Here is an example of how the package name works in correlation with the APK:
----------------------------------------------------------------------------------------------
/data/data/%DEVELOPER%.%APPNAME%/-1%APKNAME%.apk
----------------------------------------------------------------------------------------------
"%DEVELOPER%.%APPNAME%" would be the app package name; developers sometimes place their name or the company's name, followed by the app name. Since
namespaces are disallowed in package names, individual aspects of the package name are separated by decimals. I have found through my
many modding ventures, that
most package names begin with "com.". This is likely the result of an
SDK automatically applying a package name from its own format or template package name that slaps-on the app name when the app is
compiled.
Some apps even have multiple activities that will each have a "sub-package name" that carry out specific functions within the app. They look like something along these lines:
----------------------------------------------------------------------------------------------
%DEV%.%APP%:
->%DEV%.%APP%.%ACTIVITY01%
-->%DEV%.%APP%.%ACTIVITY02%
--->%DEV%.%APP%.%ACTIVITY03%
----------------------------------------------------------------------------------------------
These sub-activities function like
entry points, and are essentially the same thing.
I suppose when it comes down to it, the package names and activities are decided by the developer and will vary per app. Often times parts of these names are abbreviations of things like the company or specific function. Some of these names can even be inferred as to what they are, or even do, based on the given names or labels they have.
Hope this helps.
