Android source code import and debugging methods

A. download the compiled Android system source code. The compiled source code contains the compiled content in the out folder B. set android2.2/development/IDE/Eclipse /. copy the classpath file to the root directory android2.2/C. create a Java project, select Create project from existing source, and select android2.2/D as the source path. follow the default Java Project (note that it is not an android project) to create the project. Note that the default project will reference four jar packages: javalib. jar, Arity. jar is required. The other two jars are not in the source code. They are jar packages prefixed by Google. They can be downloaded or not required. It only affects several lines of code, note that the Project Creation and compilation process will be slow due to the large amount of code. E. I didn't reference Google's jar package here. It's not very important to make a few errors. I comment it out, because our project can only be used for debugging code, and all the modifications won't work for the application, we only need to ensure that the compilation is successful. F. start the vm g. debug application. Note that you cannot debug the entire source code project like the android project. You can only select the corresponding package of an app for debugging. Note that you need to perform debug h according to the operation. obtain the ddms remote port number of the application to be debugged from the ddms view, and set it to I. okay. Now you can debug the corresponding system application process code. You can go to the ddms view and check whether the application process enters the debug mode.
