make and make otapackage

Question

In AOSP development does make otapackage command do everyhing as make command with additionally creating .zip file? Reason I am asking is because right now for making otapackage I first execute make and than make otapackage, and I was wondering if first make is unnecessary?

I have found some posts but I am not 100% sure if I understood.

Running “make” will produce a basic, image based build, which is not easily flashed to a device. Chances are, you want to build a flash-able update.zip style file which can easily be installed to a device. To do this, use the command “make otapackage” (for CyanogenMod ROMs, “make bacon” is used instead).

Answer 1

While make might be a subset of make otapackage right now, if this property is important to you I suggest you instead run make droid otapackage. The default goal of the Android build system is "droid", i.e. make and make droid are equivalent. Asking for both goals in the same invocation of make is more efficient than running make followed by make otapackage and is guaranteed to produce the results you're looking for.

(Unless, obviously, in the unlikely event that the default goal changes from "droid" to something else.)
