android - React Native Release: Could not connect to development server -

-

i followed official guide create installable android application.

however when installing apk ./gradlew installrelease app crashes react fragment loaded: 

runtimeexception: not connect development server.

my fragment code looks this, integration android tutorial suggests.

@override public view oncreateview(layoutinflater inflater, @nullable viewgroup container, bundle savedinstancestate) {     mreactinstancemanager = reactinstancemanager.builder()             .setapplication(getactivity().getapplication())             .setbundleassetname("index.android.bundle")             .setjsmainmodulename("index.android")             .addpackage(new mainreactpackage())             .setusedevelopersupport(false) // changes nothing             .setinitiallifecyclestate(lifecyclestate.resumed)             .build();     mreactrootview.startreactapplication(mreactinstancemanager, "helloworld", null);     return mreactrootview; }

do have ideas might wrong? react native need development server if app packaged release? can`t believe that.. want app running is.

as @rmevans9 mentioned in comments above, need not have development server release or development mode (you using offline bundling capability then).

one interesting point mentioned in code: 

.setusedevelopersupport(false) // changes nothing

if set true, app work connecting local server? if not, guess react application using isn't registered "helloworld" using in app invocation.

 mreactrootview.startreactapplication(mreactinstancemanager, "helloworld", null);

make sure name matches registered in react native app.

i use winscp download , edit .scss files , sass on linux (on server) compile them .css . after saving file, use: sass scss/style.scss css/style.css , replaces css file compiled sccs. the problem i want skip part return command line after editing scss file, sake of automation , saving time. but, if use watch command: sass --watch scss/style.scss:css/style.css synchronize 2 files, alerts nonexistent css errors pop up: change detected to: scss/style.scss error scss/style.scss (line 232: invalid css after "...ht: bold; line-": expected "{", "") note that when file uploads quicker usual (sometimes happens) watch command job, no errors. this because, when file upload takes time, sass compiles scss file (on server) before uploaded remote folder. thus, compiles part of file, resulting in css errors. is there way set timer watch command waits few seconds after detects changes , before compiling? any other way overcome is, of course, ...
