angular - Ionic 2 App fails to load on production build for android version 4.4.2 and below -


i building ionic v2 app , having issue older version of android.

on versions including or older 4.4.2, after splash screen white screen. if inspect app, error is:

    uncaught error: no ngmodule metadata found 't'.

('t' in case 'appmodule' replaced t during minification step)

when build app development/debug build, app can run on devices running android 4.4.2. :

    $  ionic cordova run android

however, if add --optimizejs or --release error message wrote above:

    $  ionic cordova run android --release

or

    $  ionic cordova run android --optimizejs

any ideas around this? should restrict api level 21 , above? guess there browser issue in 4.4.2.

i created new project scratch. added android platform back. reinstalled plugins. still gave me same results.
