I had downloaded the Android Open Source Project,
try to understand the file architecture and the source code of Android native application
(e.g. Browser, Contacts). And I also use adb to see what apk is included in SDK.
I found they are different, so I have following questions...
(1). I can find Calendar folder in Android Open Source Project, but can not find Calendar.apk in SDK,
does that mean the related source code is not compiled and released to (included in SDK) App developers?
(2). Does anyone know how to check/read the "make file" of Android Open Source Project?
We do have Calendar app source code, but in SDK, I can not find Calendar.apk, I guess it is because the
Calendar app is not built. Can we prove my assumption by checking make file?
(3). There is an IM app in the Android Open Source Project and G1, but I can not find IM.apk in SDK, why?
(4). I can find STK folder in Android Open Source Project (/packages/apps) but no STK.apk in SDK, why?
(5). There are Sync, Updater, VoiceDialer folders in Android Open Source Project (/packages/apps),
but no such apks in SDK, why?
(6). Maps.apk can be found in SDK, but where is the source code in Android Open Source Project?
(7). There is a Street.apk in SDK, what is that? I can not find a shortcut on home screen to execute it.
(8). Where is the source code of Street.apk in Android Open Source Project?
(9). What is GoogleApps.apk? How can I launch this application? where is the source code?
Any comment is appreciated.
