Case: eBay for iOS
.app package: 112.9MB
Excluding all the frameworks, all the graphical resources, etc.
The binary is a whopping 30.7MB
Okay that it has armv7 and armv8, then again, it's already 15 megabyte per architecture.
And the App is really simple, specially compared to a fully featured web browser like Opera!
- vinayan3 9y agoIt takes a bit of engineering to cut binary sizes down. It depends on how much they care and the cost they incur by having larger binaries. With building mobile apps you get a prebuilt XCode project and it takes a lot of effort to tinker with it to reduce binary size.
- Tanegashima 9y agoI understand that. But how could the executables? You know, the machine code, get so big. And I'm comparing installers with just the app!
- vinayan3 9y agoThe machine code can be so big because people put huge strings as constants. As I mentioned cutting down binary size comes from working on the code and understand how the complier translate it into machine codes. The compiler could unravel a loop, inline functions, etc... The compiler is making decisions about binary size vs speed for you. There are ways to tell it not to do that.
- flukus 9y agoWhat does the ebay app do that it needs different binaries instead of the standard <whatever an android jar> is called?
- vinayan3 9y agoAPK? Well he's talk about iOS even then on Android you can write native code and compile to armv7 etc... and have optimized binaries for certain CPUs.
- flukus 9y agoAh, didn't realize it was iOS, didn't know iOS ran on multiple architectures for that matter. Is there a reason (other than incompetence) they don't just publish 2 versions for the different CPU's?
- Tanegashima 9y agoThis is iTunes download. When the user downloads, he downloads only the version that works with their CPU.
