Bare React Native OTA Updates Setup

Wire over-the-air updates into a bare React Native app: AppDelegate on iOS, MainApplication on Android (both templates), and the channel SDK key.

Two edits per platform: point React Native at the OTA bundle, and add the channel key from ota init. The same key goes in both platforms.

Android

Return the OTA bundle from MainApplication

This is what makes updates take effect — React Native asks the host for a bundle path at start-up, and the SDK answers with the newest healthy downloaded bundle. Which edit you need depends on which template your RN version generated.

android/app/src/main/java/…/MainApplication.kt

import com.otaupdate.OtaUpdate

override val reactNativeHost: ReactNativeHost =
  object : DefaultReactNativeHost(this) {
    override fun getJSMainModuleName(): String = "index"

    override fun getJSBundleFile(): String? =
      OtaUpdate.getJSBundleFile(applicationContext)   // <- add this
  }

Add the key

android/app/src/main/res/values/strings.xml

<string name="ota_deployment_key" translatable="false">ota_live_xxxxxxxxxxxxxxxxxxxxxxxx</string>

That's it — the SDK already knows which server to talk to.

iOS

Install pods

terminal

cd ios && pod install

Return the OTA bundle from your AppDelegate

ios/AppDelegate.swift

import OtaUpdate

override func bundleURL() -> URL? {
#if DEBUG
  return RCTBundleURLProvider.sharedSettings().jsBundleURL(forBundleRoot: "index")
#else
  return OtaUpdate.bundleURL()          // was Bundle.main.url(forResource:…)
#endif
}

Add the key

ios/<YourApp>/Info.plist

<key>OtaDeploymentKey</key>
<string>ota_live_xxxxxxxxxxxxxxxxxxxxxxxx</string>

Same key as Android. The device reports its own platform on every check.

Building staging and production from one project

Give each build variant its own strings.xml / Info.plist value (an Android product flavour or build type, an Xcode configuration) and paste the matching channel key into each. The channel then travels with the binary, so a staging build can never take production updates.
