I have always been told I’m stubborn. And I am. So jumping off this post, I continued doing instant apps stuff and I learnt more things this week.
- More than I figured last week, data binding is broken. As in broken broken. Do not use AS3.0 Canary 9 if you want to look at multi-feature instant apps and your data binding files will NOT be in the base module.
- I seemed to have hurt AAPT2’s feelings. It seems to have a vendetta against me. First it was complaining of (insert eyeroll) 9-patch image errors, then it became Manifest errors, and then I gave up and turned it off again. To do that, add
- BUT! If you are doing the thin feature approach described in my previous post, AAPT1 fails if your instant app has multiple features. Remember that for multi-feature instant apps, common resources should be in a
base featuremodule. That means your library which your feature depends on (which in turn depends on the
base feature) does not have access to any of the things declared in
values.xmland such. I filed a bug for this, please star!
- There are a lot of improvements in AS3.0, but there are also some caveats. To test an instant app in the emulator, you have to run it from Studio (
adb installfor an instant app DOES NOT work – AS will install it as a full app). You can (should?) use
adb install --ephemeral FEATURE_APK1 FEATURE_APK2 FEATURE_APK3on an O device (but there is a bug on O emulators so YMMV)
- Set your run configuration to launch a URL. If AS won’t let you change the default launch options, delete the configuration and make a new one
- Signing configs need to be in all feature modules. Once that’s defined, absolutely do not forget to reference it in your build types!!
I haven’t figured out everything, so it is very likely that I will have more of things to say!
