1203730 - Add CardView to build system

Status: RESOLVED DUPLICATE of bug 1271428

(Firefox for Android Graveyard :: General, defect)

Description

[Michael Comella (:mcomella) [NI reported issues only; no longer employed by Mozilla]]

Like bug 1171288 for recycler view.

Also, figure out how much larger it makes the build.

43765308 bytes with Cardview (and a little code to use it, ensuring it's not removed by PG)
43677376 bytes without

Delta: ~87.932 kb. For comparison, the xxhdpi dropshadow we currently use for doorhangers is 672 bytes. :\

Nick, this seems like too much to me (for easy drop shadows and rounded corners) – what do you think?

Note that I just copied the patterns from the recycler view bug 1171288 and I
didn't closely check what I was doing.

Note: it's only worth reviewing this if you think it's worth adding CardView.

We'd also be able to remove RoundedCornerLayout (1k) and the associated hackery for that, but that doesn't come near recouping the 85k.

I agree, but I am quite surprised by this result.  How did you test this?

The AAR is only about ~20kb; we shouldn't go up by more than that unless we see some very surprising PG behaviour.  Push a try build, so we can see the automation PG outputs.

In general, I am for using these kinds of libraries, but the barrier to entry can't be "I asked Nick".  I suggest you solicit feedback from sebastian and perhaps one other person likely to use the library; collect pros and cons; and then surface the discussion to mobile-firefox-dev.

And I mid-aired liuche, who contributes exactly the kind of comment I was hoping for!  Thanks, liuche :)

I'd rather re-visit after Bug 1108782, which would use the AAR for this.  That ticket should land shortly.

I built with the patch in this bug and the WIP patch in bug 1203345 comment 3. Then I `ls -alh` the output fennec*apk. Similarly, I updated to the fx-team changeset closest to that branch and ran the same command.

Unassigning self at least until bug 1108782 is fixed.

My guess is that you want to force PG passes -- by default, local builds do 1 pass, but automation does 6.  Just push to try :)

I fixed some merge errors and renamed some stuff - try run here: https://treeherder.mozilla.org/#/jobs?repo=try&revision=8738e623ab56

I didn't make any changes to the junit3 moz.build files even though I see the recyclerview libraries are included because I don't think we have any junit3 tests that run doorhangers, but I could be wrong about about them not being needed.

This would set the stage for removing RoundedCornerLayout and the shadow resources, and fixing some of the offset regressions. I did a quick test and CardView works fine with a quick replace, although there are some problems on (surprisingly) non-2.3 devices with multiple doorhangers.

It's worth pushing an API 11 try build, since that's more representative.  For API 9:

From https://treeherder.mozilla.org/#/jobs?repo=fx-team&revision=b404b452db2b

Size of classes.dex: 4248396 bytes
Size of fennec-44.0a1.en-US.android-arm.apk: 40912617 bytes
Size of libxul.so: 23648911 bytes
Size of omni.ja: 9735189 bytes

From the try build at https://treeherder.mozilla.org/#/jobs?repo=try&revision=8738e623ab56

Size of classes.dex: 4344732 bytes
Size of fennec-44.0a1.en-US.android-arm.apk: 41000665 bytes
Size of libxul.so: 23640991 bytes
Size of omni.ja: 9734974 bytes

41000665 - 40912617 = 88048.  It must be that the AAR file compresses well.

And https://dxr.mozilla.org/mozilla-central/source/mobile/android/b2gdroid/app/Makefile.in#32 please.  (You would see this if you pushed to try against 'android-b2gdroid'.)

If it works for you, it works for me :)
