The project is used to explore how customized Android Frameworks sync up with official Android Frameworks. 1. Clone corresponding customized Android Frameworks into directory platforms. 2. Retrieve commit history of customized Android Frameworks and store into directory history. 3. Run Python scripts to acquire merge and conflict information. Every Python script contains the specification of the intention at the beginning of the script. However, the path specified in the script should be replaced with the local path as I am using the absolute path. Libs: contains the Java jar files used in the Python scripts. Outs: contains some of the output of Python script. Scripts: contains Python scripts used to do the experiments. history: contains most of the experimental data in the research. Every directory named by the project name contains branch information. We detect different branches for every different Android customizations. history/android\_base: contains different output of the detection.
