I want to do a static analysis on java part of AOSP, which requires all .aidl files to be transformed to .java files, so that the entire project tree is java only (ignoring cpp or other languages).

I have searched the doc and know that there is a executable tool named aidl which can help you transform a single .aidl file in a single time. However I am afraid that this is not the best way when considering the whole project.

So I am wondering if there is a state where all .aidl files are transformed to .java file while compiling the AOSP? If there really is, how to achieve that state?
