Having problem running android emulation with react native package

I'm having the same problem running the android emulation as the following guy in this link.

https://stackoverflow.com/questions/47605454/getting-this-error-android-repositories-cfg-could-not-be-loaded

react-native run-android
Scanning folders for symlinks in /Users/jloi/dev/lndr-mobile/node_modules (10ms)
JS server already running.
Building and installing the app on the device (cd android && ./gradlew installDebug)...
File /Users/jloi/.android/repositories.cfg could not be loaded.

FAILURE: Build failed with an exception.

* What went wrong:
A problem occurred configuring project ':app'.
> Could not resolve all dependencies for configuration ':app:_debugApk'.
> A problem occurred configuring project ':urbanairship-react-native'.
> Could not resolve all dependencies for configuration ':urbanairship-react-native:_debugPublishCopy'.
> Could not find any version that matches com.facebook.react:react-native:[0.40,).
Versions that do not match:
0.20.1
0.20.0
0.19.1
0.19.0
0.18.0
+ 12 more
Required by:
LNDR:urbanairship-react-native:unspecified

 

Please advise.  Thanks.

    Fixed it by adding build.gradle but now i get

    maven {
    url "https://maven.google.com"
    }
    maven {
    // All of React Native (JS, Obj-C sources, Android binaries) is installed from npm
    url "$rootDir/../node_modules/react-native/android"
    }
     

     

    :app:incrementalDebugJavaCompilationSafeguard UP-TO-DATE
    :app:compileDebugJavaWithJavac
    :app:compileDebugJavaWithJavac - is not incremental (e.g. outputs have changed, no previous execution, etc.).
    /Users/jloi/dev/lndr-mobile/android/app/src/main/java/com/lndr/MainApplication.java:6: error: package com.urbanairship.reactnative does not exist
    import com.urbanairship.reactnative.ReactAirshipPackage;
    ^
    /Users/jloi/dev/lndr-mobile/android/app/src/main/java/com/lndr/MainApplication.java:30: error: cannot find symbol

    symbol: class ReactAirshipPackage

    :app:compileDebugJavaWithJavac FAILED

    FAILURE: Build failed with an exception.

    * What went wrong:
    Execution failed for task ':app:compileDebugJavaWithJavac'.
    > Compilation failed; see the compiler error output for details.

    * Try:
    Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.

    BUILD FAILED

    Johnny,

    You shouldn't need to modify the gradle file.

    It seems like the first error originated from not having updated the react-native version.

    Can you ensure that you have the least 0.40 of the react-native module?
