Stale ODEX dependencies cause unbootable Android

This document is based on the code of Android 4.1.1_r6.1 (Jelly Bean).

Suppose that you want to customiz your android system, you may want to modify /system/framework/framework.jar (source files are in the directory frameworks/base). During development, let's assume that you just did a full build, and you decide to make some changes to some source files. After that, you want to build again. Ideally, the building system can correctly re-build everything that is dependent on the changes you just made. However, seems that the android building system does not do it properly. You will get an unbootable image caused by mismatched dex signature. If you check the log when system boots, you will see an error message like the following:

07-30 06:50:56.042: I/dalvikvm(393): DexOpt: mismatch dep signature for '/system/framework/framework.odex'
07-30 06:50:56.042: E/dalvikvm(393): /system/framework/apache-xml.jar odex has stale dependencies

The reason is
