(I'm sending this message on Android developpers forum). Hi; I'm trying to develop some middle layer application based on the source tree from android.git.kernel.org. I'm using the libmedia.so to link my code and has no problem. I also tried to link my code using the other libmedia.so which I pulled from HTC ADP2 (I ordered last week) and found that my code have many undefined references to some functions (or method). This make me think that source code I gitted from android.git.kernel.org (two weeks ago) does not sync which the code in the HTC ADP2 Android device. Could someone help me on -- how do I sync my source tree with the HTC ADP2 ? Thanks very much.
