javascript - React native android application has stopped

Question

I've stuck with an android version of an application (this one with "Welcome to React Native!" text). After this, I did exact steps as a documentation says. After build android version of this application, i copied signed version of APK file on my device and install it - when i'm trying to launch it then i receiving message "Unfortunately, FirstProject has stopped". Debug version of this application working fine. I've spent almost a week trying to run this, and i didn't find any solution. Do any one have any idea what i'm doing wrong?

Regards

I think the problem lies here. In the latest releases, pro guard is enabled by default. Try disabling it in android/app/build.gradle :

buildTypes {
  release {
      minifyEnabled enableProguardInReleaseBuilds
      proguardFiles getDefaultProguardFile("proguard-android.txt"), "proguard-rules.pro"
  }
}

Change this :

def enableProguardInReleaseBuilds = true 

to this :

def enableProguardInReleaseBuilds = false 

Then run the steps again to create you APK.
