I have a copy of the Android source code, but don't know what version of android it is (I downloaded it a while ago and can't remember if I synced to the head of the repo or not).
It there a way to determine this? I've looked in the manifest for a couple of the sample projects and they state:
<uses-sdk android:targetSdkVersion="11"/>
so I think I can assume it is either 11 or above, but I'm not certain which one. This is what the file structure looks like:
I assume that's the platform/ directory. If so, take a look in frameworks/base/api. You'll find a text file representing each API level that's been committed -- find the largest numbered file in that directory for your answer.
Example: https://github.com/android/platform_frameworks_base/tree/master/api
The AOSP SDK version is defined in build/core/version_defaults.mk.
