Someone said delete the files in assets and run under command can help, but I tried it and no use, feeling confused.

react-native bundle --platform android --dev false --entry-file index.js --bundle-output android/app/src/main/assets/index.android.bundle --assets-dest android/app/src/main/res/

I tested other mobilephone but no use. Please help me ,thanks a lot.

Just fixed the problem after hours of headache. for me, the problem was one of my dependencies was using ** operator which was not recognized by my babel compiler (apologies if I misused the terms, I am not very experienced with these staff). so I went there and changed ** operator with the regular Math.pow().

for me the file that was causing the issue was \node_modules\react-native-elements\src\tooltip\getTooltipCoordinate.js third line, in react-native-elements library.

check your last installed libraries for same operator and replace. probably not the best way to fix it but at least you’ll know what’s causing the issue.
