React-Native : Can't show remote images in release mode on android device

Question

im runing a simple react-native application in my android device (samsung 9, Android 9, API 28), so on debug mode it\'s work fine using this commande line :

react         


        

Answer 1

We were having crashes and issues in development with our icons not being written out and appearing like images_homeactive. This caused react-native-navigation to crash our app

This occurred when we upgraded to compileSDKVersion = 28.

Starting with Android 9 (API level 28), cleartext support is disabled by default

this prevents your application from connecting to the React Native packager. The changes below allow cleartext traffic in debug builds.

../app/src/main/AndroidManifest.xml


../android/app/build.gradle
buildTypes {
    release {
        ...
        manifestPlaceholders = [isDebug:false]
    }
    debug {
        ...
        manifestPlaceholders = [isDebug:true]
    }
}

So thankful to stumble upon Ahmed's answer. Hope this helps someone.
