When Only EAS Build Fails with "No matching variant", Check Your Local android/build First
Gradle passes on your machine, but the Android build on EAS stops at "No matching variant of project". Reading the reports on GitHub, I traced how a Windows-generated autolinking cache can reach the Linux builder, and wrote a small script that checks for it before you queue a build.
App Review Says "Guideline 2.1, Blank Screen": Three Places to Look in an Expo Release Build
It opens fine in TestFlight, yet review rejects it for a blank screen. Here is the order I check things in an Expo + EAS release build: which environment holds your variables, secret visibility during config resolution, and what the reviewer's device does differently.
When only notifications fail in Expo Go: three checks, then the shortest move to a development build
If push notifications never reach your Android device in Expo Go, check these three things before touching device settings, then move to a development build with the fewest steps. Also: how to spot what else Expo Go can't test.
A build that stops with exit code 0 — the flag that silenced the log, and the check that let an empty file through
Two reports landed in the same week: eas build --local stopping with exit code 0 but produced no further output, and a zero-byte stub that never got embedded. Both came down to settings that reduce output. Here is how to audit your own scripts.
Adding .easignore stops EAS from reading .gitignore — count what actually ships to the build
EAS Build decides what to upload from .gitignore, and the moment you add .easignore the two swap places. Here is how I count the bundled files before sending, plus a measured result: once a parent directory is excluded, an exclamation mark cannot bring a file back.
Leave image out of eas.json and an SDK bump moves your Xcode and pnpm too
If eas.json has no image field, your builds run on the auto alias. Move one SDK alias and Xcode, Node.js, pnpm and fastlane all change together. Here is how to read the image name out of your last green build and decide whether to pin it before Xcode 27 lands.
A beta-SDK build can reach TestFlight, but it can't reach review
Builds made with a beta Xcode can be distributed through TestFlight, but they cannot be submitted for App Store review. Here is how to check which SDK produced your build, and how to protect your release profile in eas.json.
Version code 1 has already been used — who owns that number, app.json or EAS?
When a Play upload stops on versionCode, check where the number actually lives before bumping it. A one-command way to tell whether app.json, EAS, or build.gradle wins.
Rork × Vision Camera v4: A Production-Grade Camera Stack with QR, OCR, and ML Inference
Wire React Native Vision Camera v4 into a Rork project end-to-end — frame processors, ML inference, QR/OCR, plus battery and thermal tuning, a real-device test matrix, store review, and a staged rollout.
Adding Expo Dev Client to Your Rork App
Added a native module to a Rork app and Expo Go no longer opens it? Here is how to set up Expo Dev Client (a custom development build), including the prebuild trap, when a rebuild is needed, and how EAS Update fits in.
Make ITMS-91053 Stop Catching Your Rork Max App — A Release-Proof Privacy Manifest Workflow
Fixing ITMS-91053 once doesn't keep it away — every new dependency can bring it back. Here's a field-tested workflow to audit your dependency tree, generate declarations, and catch the rejection locally before you upload.
Fixing 'JavaScript heap out of memory' in Metro and EAS Builds
Your Rork or Expo build dies with 'FATAL ERROR: Reached heap limit Allocation failed - JavaScript heap out of memory.' Here is why it happens and exactly how to fix it, both locally and on EAS Build.
