Generate Play Store screenshots on Gradle managed devices

[yukuku]

Replaces the Play Store screenshots with generated ones, and adds the machinery that generates them.

Why

The screenshots on the store were roughly a decade old (Nexus 5 / Nexus 9 frames running Android 5/6 chrome) and below Play's current requirements:

	Before	Play wants	Now
Phone	576x1024, 7 shots, 2 of them landscape composites	≥1080px short edge, long edge ≤ 2x short	1080x1920, 8 shots, all portrait
Tablet 7"	1024x576, 4 shots	documented range 1080-7680px	2048x1536, 8 shots
Tablet 10"	1024x576, 1 shot	at least 4	2048x1536, 8 shots

Quick Bible had graphics for en-US only; all eight of its listing languages now have their own.

How

StoreScreenshotTest reaches each screen by launching its activity through an intent rather than tapping through the drawer. Tapping would mean matching on-screen text, which changes in every language the capture runs in.

ScreenshotSeed fills the content each screen reads, because most of them are empty on a fresh install:

Screen	Seeded with
Reader, highlights, notes	Markers on Psalm 23 and John 3:16
Devotions	Today's article — Renungan Pagi for Indonesian flavors, Morning & Evening otherwise
Reading plan	The M'Cheyne plan from an .rpb fixture, first five days ticked
Songs	Four public-domain hymns in a book named "Hymns"

The devotion has to carry today's date, because the activity opens on today and would start a download for any other day. Seeding clears first, so repeat runs do not accumulate duplicates.

Audio is the exception: it needs sets fetched from the server rather than rows in the database. That shot taps the reader's audio button, matching on its view id so it works in every language, and waits for playback. The frame ends up showing real playback with the follow-along verse highlight — a feature not one of the ten store listings currently mentions. Without network the button is absent, the tap is skipped, and the shot falls back to the plain reader rather than failing the run.

Every listing language comes off a single device. The app's language is its own pref_language setting, independent of the device locale, so the test writes that preference and launches the next activity. Quick Bible's eight listings are two emulator runs, not sixteen.

tools/screenshots/capture.py drives the whole thing and files results into Alkitab/src/<flavor>/play/listings/<language>/graphics/, where tools/play/publish.py push picks them up:

ALKITAB_PROPRIETARY_DIR=/path/to/proprietary \
  python3 tools/screenshots/capture.py --flavor yuku_quick_bible

Two build fixes that fell out of this

• Production debug variants were broken. copyProprietaryGoogleServices<Flavor> writes into src/<flavor>/, and only the release path ordered it before resource generation, via its validate<Variant>FirebaseConfig task. Any yuku_alkitabDebug build therefore failed Gradle's implicit-dependency check. The copy now hangs off pre<Variant>Build, which covers every consumer.
• Managed devices need a GPU setting. The full aosp images reject AGP's default -gpu auto-no-window, so gradle.properties sets android.testoptions.manageddevices.emulator.gpu. The smaller aosp-atd images boot without it but have no rendering stack, and every screenshot taken on one is solid black.

Verified

Ran end to end for both flavors. 216 screenshots, every one checked against Play's rules by script — all at least 1080px on the short edge, none exceeding a 2:1 ratio, 8 per bucket, zero violations. Content spot-checked across languages: Indonesian reader with seeded highlights, Korean marker list, Russian reading plan, Indonesian devotional, audio bar mid-playback. testPlainDebugUnitTest, testPlainReleaseUnitTest and assemblePlainDebug all pass.

Not included

Framing and captions, so the tablet captures still show the emulator taskbar along the bottom. Split-screen version comparison is not captured: it needs a second version installed, which the bundled internal version cannot provide. The reading plan fixture is an English-titled ESV plan, so the plan name stays English in a localized capture (the daily readings inside it do localize). The listing text problems from the same review (no listing mentions the audio Bible, contradictory version counts, leftover Traditional characters in zh-CN) are a separate branch.
