As described in Bug 1370156, we have observed that after landing Bug 1341990, the string table entry is greatly increased for Gradle build while nothing happens for mach build. My guess is that there are some optimization in mach build and it is worth studying to minimize our apk size with Gradle build.

This may be a false alarm regarding current investigations: The suspect was triggered by this https://bugzilla.mozilla.org/show_bug.cgi?id=1367768#c12 test on my local machine, but builds on mozilla-central Treeherder have shown otherwise, see: https://bugzilla.mozilla.org/show_bug.cgi?id=1370156#c3 Further clarification and investigation would be needed to determine if this is a real bug. I might do it later after some more emergent tasks but anyone is welcomed to look into this in the meanwhile.

Re-triaging per https://bugzilla.mozilla.org/show_bug.cgi?id=1473195 Needinfo :susheel if you think this bug should be re-triaged.
