Your Widget Extension Can Submit a BGTaskScheduler Request. It Just Cannot Register the Handler
Calling BGTaskScheduler from a widget extension compiles, submits, and returns true — and then nothing runs. Here is why registration belongs to the host app only, and how I moved refresh ownership back where it belongs across my wallpaper apps.
EAS secret visibility does not keep a value out of your app — deciding prefix and visibility separately
The EXPO_PUBLIC_ prefix decides what ships inside your app; EAS visibility decides who can read it. Why stacking them blanks a value on OTA updates, and how to check your build.
When a link opens the browser instead of your app, look at the signing key before assetlinks.json
Android App Links fail silently when the certificate fingerprint does not match. Here is the real keytool output, the upload key versus app signing key trap, and a small checker you can run before you deploy.
My Second App From the Same Codebase Ships With a Distinct-Value Manifest
Google Play has drawn a clearer line around low-value apps. Here is how I decide where the distinct value of a sibling app lives, and the small script I run before every submission to check that the two apps have actually diverged.
I counted how many versions expo install starts recommending after one patch bump
What expo install recommends is tied to the patch version of expo itself. I measured the ledger diff against the npm registry, how far npm install drifts, and the one check worth adding to a generated project.
Starting with the EAS Observe free tier, and why Crashlytics stays installed
EAS Observe reached general availability on August 20. I looked into consolidating down to one monitoring service and found that native crashes are still out of scope. Here are the free-tier limits and the setup details that trip people up.
expo-doctor passes on API level 35. Here is what its 22 checks actually cover
I opened the expo-doctor 1.20.4 bundle and listed every check it registers. Only one looks at store requirements, and its threshold is still API level 34.
Nine Expo patches shipped in thirty days. Which one is your app actually running?
A tilde in package.json does not mean you are on the newest patch. The file that decides what actually gets installed is package-lock.json. Here is what npm did when I ran the checks myself.
Sunset.png and sunset.png: one file on your Mac, two on the build server
An image that renders locally but breaks the cloud build. The cause was filename casing. Here is the reproduction, the git behavior behind it, and a small checker with measured results.
I Split Rork and Claude Code by Who Owns the Build Environment
How to decide between Rork and a terminal coding agent using data from your own repository instead of impressions of generated code. Includes a script that counts which layer your maintenance work lands in, and a check that catches native settings silently disappearing on regeneration.
Bumping targetSdk to 36 surfaced a 16 KB warning. These are two different deadlines
The August 31 target API 36 requirement and the February 1, 2027 16 KB page size requirement are separate conditions. Here is how to inspect your AAB without installing the NDK, and why a LOAD misalignment and a zip boundary miss need completely different fixes.
The names you can change, and the ones you can't — the 30 minutes before your first Rork release
An app has three names, and only the display name can be changed after release. Here is how I check the identifiers Rork fills in by default, using a dependency-free script, before I hit submit.
