React-native build - APK

Question

I am using two methods to build an APK in React Native project.

using react-native run-android and take the latest apk from projectFolder>android>app>build>output>apk.
react-native bundle --dev false --platform android --entry-file index.android.js --bundle-output ./android/app/build/intermediates/assets/debug/index.android.bundle --assets-dest ./android/app/build/intermediates/res/merged/debug

then run:

cd android
gradlew assembleDebug

then physically locate the file at android/app/build/outputs/apk folder:

app-debug.apk
app-debug-unaligned.apk

The problem I am facing is that if I am building apk from above-mentioned methods then generated apk is not the build of updated code. But the same code which I am running on the Android simulator of Android Studio is working perfectly. Also if I am using a real device as an emulator connected to the android studio, it's running on the older version of build.

@halfer I apologize for my way of asking help, but this was a kinda high priority issue for me... hence I was desperate to seek help from others. — rohit kumar, Mar 05 '18 at 05:20
can't do so..... it says you are banned from this..... i am sorry — rohit kumar, Mar 12 '18 at 09:46
Ah, I see. There are various instructions on the _Meta_ site to explain how to get out of an answer ban, [see here](https://meta.stackoverflow.com/search?q=answer+ban). It means that some of your answers (potentially including deleted ones) were not well received, and a block was automatically applied by the system. I believe you can try to tidy up recently deleted answers and then undelete them to try to attract upvotes on them, or improve existing non-deleted ones. — halfer, Mar 12 '18 at 10:12

This was solved as follows:

enable usb debugging.
download latest usb driver for phone.
setx PATH "%PATH%;C:\Program Files\android-sdk\platform-tools" (see here)
execute adb. exe from C:\Users[youruser]\AppData\Local\Android\android-studio\sdk\platform-tools
run adb devices in cmd to see list of connected devices
Run the following in a command prompt:
```
$ adb -s <device name> reverse tcp:8081 tcp:8081
```
To find the device name, run the following adb command:
```
$ adb devices
```
