The Back Button Showed an Interstitial Sometimes, Not Others — Rewriting Nested ifs Into a List of Independent Guards
Interstitial display on back press was unstable because nested if statements hid the priority between conditions. Here is how I split it into reason-returning guards and generated tests from a decision table.
A Few Low-Density Phones Lost Their Bundled Wallpaper — The drawable vs nodpi Boundary in Play's Density Splits
App Bundle density splits will happily split images that should never be split, dropping a static resource on one density bucket only. Here is how I reproduced it with bundletool and fixed it by moving to drawable-nodpi or disabling density split — with the decision criteria.
I Started the Ad SDK Before Asking for ATT — the Init-Order Bug That Quietly Lowered First-Session eCPM
When I rolled AdMob mediation out to four iOS apps, only the very first session showed weaker ad revenue. The cause was the order between the ATT prompt and MobileAds initialization. Here is why the order matters, plus how I had Antigravity audit the init sequence across all four apps.
Rebuilding Wallpaper Image Delivery Around Resolution Buckets — Letting an Antigravity Agent Own Conversion and Validation
Every new device resolution quietly makes a wallpaper app heavier. I stopped shipping one master image to every device and rebuilt delivery around resolution buckets, WebP/AVIF, and an edge redirect — then handed conversion and validation to an Antigravity agent. Real code and thresholds included.
Diagnosing AdMob Mediation Fill Rate with an Antigravity Agent — A Memo on the Revenue I Lost Chasing eCPM Alone
When AdMob mediation revenue stalls, the cause is usually fill rate, not eCPM. This memo walks through a diagnostic pipeline that lets an Antigravity agent read your BigQuery export and Firebase metrics to isolate per-network fill rate drops automatically, with real numbers from indie development.
Copilot Studio's Computer-Using Agent Next to How I Run Claude in Chrome Every Morning
Microsoft made Copilot Studio's Computer-Using Agent generally available. Here is how that announcement looks from the perspective of an indie developer who already runs Claude in Chrome against AdMob and Crashlytics every morning.
Recovering Missing iOS dSYMs Across Six Apps with Antigravity's Background Agent — A Four-Week Operations Log
After migrating Firebase iOS SDK from CocoaPods to SPM, six wallpaper apps saw their Crashlytics symbolication rate collapse to as low as 4.2%. This is a four-week operations log of letting Antigravity's Background Agent track, upload, and verify 1,847 missing dSYMs across six repositories — including App Store Connect dSYM polling and AdMob revenue reconciliation.
Implementation Notes: Running AdMob Mediation A/B Tests with Antigravity Parallel Agents
Notes from automating AdMob mediation A/B testing using Antigravity parallel agents across an indie wallpaper-app portfolio with 50M cumulative downloads. Covers joint eCPM + ARPU optimization, the 7-day rotation pipeline, and the rollout design that does not break production.
Phasing AppLovin MAX into iOS with Antigravity Editor: A Four-Week Implementation Record
A four-week record of phasing AppLovin MAX into four wallpaper apps that had been running on AdMob alone. How I split the work between Antigravity Editor's Inline Edit and Agent Mode, settled the SDK initialization order, and designed the revenue verification gates—written with real code and the decisions behind each step.
Six Weeks of Letting an Antigravity Background Agent Watch the Drift Between AdMob and Remote Config
A six-week field report on handing weekly AdMob and Firebase Remote Config diffs to an Antigravity Background Agent, with the drift cases it actually caught and the operational boundaries I ended up drawing.
Three Weeks of Running Antigravity Browser Agent and Claude in Chrome Side by Side
Notes from three weeks of running Antigravity's Browser Agent and Claude in Chrome in parallel while tuning AdMob and pre-release checks for my wallpaper apps.
Antigravity × UMP/ATT Consent Rate Optimization Agent — A Weekly Autonomous Loop That Lifts AdMob Revenue Region by Region
ATT and Google UMP consent rates are hidden levers that move AdMob eCPM by 1.3–2.0x. This is a working memo on letting Antigravity sub-agents run weekly experiments on regional consent UX across six apps, and how that lifted ARPDAU.
