Rather large increase in the .apk size from the new photon resources. Is there anything we can do to reduce/mitigate? -- We have detected a build metrics regression from push: https://hg.mozilla.org/integration/autoland/pushloghtml?changeset=6df7dff00b94cf7232b7d507eee373fe6b0435f0 As author of one of the patches included in that push, we need your help to address this regression.

The root cause is that we've added some new images/icons in Nightly for new visual refresh, aka Photon. There are few things we can do to reduce the APK size: 1. Remove resources that are unused in new visual design, we use bug 1375351 to track this issue. 2. Compress images/icons, or maybe use vector drawable instead.
Hi :wlach, Now Fennec apk size has been reduced to around 36,457,239. Can we close this bug now? https://treeherder.mozilla.org/perf.html#/graphs?series=autoland,1545789,1,2
This isn't a talos regression, but we can probably use the policy here as a guideline https://wiki.mozilla.org/Buildbot/Talos/RegressionBugsHandling Is the improvement due to fixing the root cause in comment 1, or due to other, unrelated work? * If there are still mitigations for this regression that are possible and make sense to implement, we should probably keep this open (along with outlining what needs to be fixed). * If your recommendations in comment 1 were implemented and that's responsible for the improvement, then we can resolve as fixed. * If there are no mitigations that make sense to implement and the regression is just something we have to accept, I would mark this as wontfix.
We do still have some space to reduce the APK size and there is a meta bug 942609 that records all the related works.

Argh, I didn't actually mean to mark this as fixed. But if the issues here are being dealt with elsewhere, then let's just leave this be.
