Actually, in my situation (React-native
version 0.61.5 and trying to install debug APK on device) none of the answers helped me, my solution was adding bundleInDebug: true
to android/app/build.gradle
like this:
project.ext.react = [
entryFile: "index.js",
enableHermes: true, // clean and rebuild if changing
bundleInDebug: true
]
