Dear Adobe engineers:

Since AIR sdk 16, the ADT compile our code to both 32bit and 64bit version ,but sadly it is not only duplicate our code, but also duplicate all the embedded resources include images/ sounds and vector shapes which created by flash and include as swc, this makes our app file size 1.5~ 2 times bigger than used be.

The more sad thing is even we did extremely heavy re-factory to remove each embedded resources and make them all loaded during launching by using Loader/URLLoader, the executable file is still 2 times bigger than before.

Please note that nowadays ipa file size is crucial for each of app developer , bigger the file size , less the successful downloading rate / advertisment conversion rate / upgrade adoption rate , and higher user acquisition cost , we spent quite a lot effort to try to reduce the file size byte by byte, but all of sudden , you guys just made our app 50% bigger than before.

The apple just announced they applied a new "APP THINNING" setup which will separate 32 bit and 64 bit binary targeting different devices, please consider try to help us implement such feature asap.....

I am praying everyday for you guys could do better job.

Let me do the math for you:

app's conversion rate = appstore page view / download 

the rate is 32% if file size = 80Mb and 22% if file size = 112M , it is 31% less !

every day we spend 10k USD on advertisement , which means the 31% * 100k = 3.1 k USD everyday lost

31k usd/day = 93k usd/ month = I can hire 15 more programmers and split them into 2 teams to develop both an native Android version and an native iOS version of our app  !!!


It is a huge problem for us now, and I think it is also a huge problem for Adobe , if  app/game developed by using AIR is less competitive by using other tools, why we use AIR?

How did you package the app?

We have recently updated one of our apps for iOS and Android with AIR 18 and did not encounter any remarkable change of the file size nor did we have duplicated assets within the IPA. We have exported with Flash Builder 4.7.
