Uhohs! It appears that the Google Android Code has been deleted from the Linux Kernel. The change is explained in depth at Kroah.com but the folks at RegHardware sum it up nicely:

“No one cared about the code, so it was removed,” writes Kroah-Hartman. “As I’ve stated before, code in the staging tree needs to be worked on to be merged to the main kernel tree, or it will be deleted.”

But the larger problem, he continues, is that Android uses a new lock type, new hooks for its “sometimes bizarre” security model, and a revamped framebuffer driver infrastructure. All this, he says, prevents “a large chunk” of Android drivers and platform code from merging into the main kernel tree.

Google, he ultimately argues, has forked its mobile OS.

ProgressBar is a visual indicator of progress in some operation. Displays a bar to the user representing how far the operation has progressed; the application can change the amount of progress (modifying the length of the bar) as it moves forward.

Extends work from "Android File Explorer with JPG's Exif & Photo displayed", and geoDegree class of the article "Convert Exif GPS info to Degree format", In this exercise, a new class AndroidExplorerMapView (actually, it's simliar to the exercises in "AndroidMapper") will be implemented to open a MapView locate the GPS location of a photo.

Directory tree of a typical Android project (at least those created by the "android create project" command) looks like this:

In early betas, the Android IPC was strictly synchronous. This means that service invocations had to wait for the return value of the remote method to arrive back to the caller. This is generally an advantage because the caller can be sure that the called service received the invocation by the time the remote method returns. In some cases, however, this causes the caller to wait unnecessarily. If synchronicity is not required and the method has no return value, oneway AIDL interfaces may be used.

Oneway methods are specified by addind the oneway keyword to the AIDL interface definition.

oneway interface IncreaseCounter { void increaseCounter( int diff ); }
