Direzione di ricerca

Inizia leggendo ReactActivity.onNewIntent e IntentModule.getInitialURL(); la issue identifica entrambi i punti di ingresso e include un riproduttore con una correzione per MainActivity. Segui i passaggi del riproduttore su Android e conferma che l’app riavviata segnali reproducer://second tramite getInitialURL() o un evento url.

Descrizione

Description

When Android ends a backgrounded app's process but keeps its task, a link to the app relaunches it into that task: Android recreates the activity from the task's first intent and passes the link to onNewIntent. The link never reaches JavaScript. Linking.getInitialURL() answers the task's first link, and no url event fires.

IntentModule.getInitialURL() reads currentActivity.intent, and getIntent() keeps returning the task's first intent until the activity calls setIntent() (Activity.onNewIntent). ReactActivity.onNewIntent hands the intent to its delegate without calling setIntent.

Calling setIntent(intent) first in ReactActivity.onNewIntent fixes it: with that line in the reproducer's MainActivity (its verify/set-intent branch), every round below answers reproducer://second. I'm happy to open a PR with it.

Steps to reproduce
  1. Build and install the reproducer's release APK: cd ReproducerApp/android && ./gradlew assembleRelease && adb install -r app/build/outputs/apk/release/app-release.apk.
  2. Open the first link: adb shell am start -a android.intent.action.VIEW -d reproducer://first com.reproducerapp. The screen shows getInitialURL(): reproducer://first.
  3. Background the app and let Android end its process while the task stays in Recents: adb shell input keyevent KEYCODE_HOME, adb shell am start -a android.settings.SETTINGS, adb shell input keyevent KEYCODE_HOME, then adb shell am kill com.reproducerapp until adb shell pidof com.reproducerapp prints nothing.
  4. Open the second link: adb shell am start -a android.intent.action.VIEW -d reproducer://second com.reproducerapp.

Expected: getInitialURL(): reproducer://second, or a url event carrying it.

Actual: getInitialURL(): reproducer://first and last url event: null.

A cold start on the second link (adb shell am force-stop com.reproducerapp, then step 4) shows reproducer://second.
