Porting and debugging the Android system ---> make commands commonly used in Android

1. Make-jxx
 XX indicates a number. This command will compile the Android system and generate an image. XX indicates the number of CPU cores that can be used, which is particularly useful on the configured computer, it takes less than 20 minutes for the company's 16-core Ubuntu server to execute make-j16, while it takes 4 hours for the dual-core PC!

2.Make
Snod
  This command will re-generate the image, which consumes very little time. Similar to the makeimg process of wince, it is useful if you modify some data files (such as music and video.

3. Make cts
 This command will compile the CTS and put the compiled results under the Data/APP directory of the out directory. Useful for CTs Testing

4. Make installclean
  This command clears the content in the corresponding board folder under the out directory, which is equivalent to make clean. If you change some data files (such as removing them), You 'd better execute the following make installclean command, otherwise, the files left in the out directory will be packaged.

5. mm/MM-B
  I like this command most in development and debugging. By executing this command in a modified directory, I can intelligently compile it. The output files are pushed to the target machine through ADB, debugging is convenient.

6. Make SDK
  This command can generate a publishable SDK, which has not been tried yet. It is said that jdk1.5 is required.

7. Make setting
  You can compile the setting module separately. I haven't tried it yet. I wonder if I can compile the e-mail and music modules separately.

8. Make bootimage

  Use this command to generate boot. IMG, which contains Linux
Kernel, RAM disk, the generated boot. IMG can only be burned through fastboot, which is useful when only the Linux kernel is modified.
