Summary

In this chapter, we learnt about the workflow of updater, which is the one actually to do the work of the OTA update. The updater interprets the updater script inside the OTA package to perform the update. We don't have to create the updater script by ourselves. It is created during the build process automatically. You may have some questions here, since you may use some recovery packages created by open source developers or ROM developers. You may even use recovery distributed by LineageOS/CyanogenMod or TWRP. How do they relate to the topics that we discussed in this chapter? These are the topics that we will cover in the next chapter.
