React-native 不会更新 android 中的更改

When i try to run on android the latest code is not updating. However, i can see the changes on IOS device. I tried reseting the cache react-native start --reset-cache , i reinstalled watchman.But nothing helps me. Could anyone figure it out?

Answer 1

finally i got the issue.I run the command react-native log-android and i got this error adb invocation failed

so i link adb with exporting path.

1. echo 'export ANDROID_HOME=/Users/$USER/Library/Android/sdk' >> ~/.bash_profile
2. echo 'export PATH=${PATH}:$ANDROID_HOME/tools:$ANDROID_HOME/platform-tools' >> ~/.bash_profile

3. source ~/.bash_profile

Now code are reflected on android device too.

Make sure React Native Server is running. If it is not running than do following

steps :

1) go to project path : cd '/home/himanshu/ReactNative_CLI/DemoApp'

2) Execute this command to start server: "react-native start"

3) if project not running : "react-native run-android"

4) Save file on your editor and you can see the changes on your device / emulator:

Note: make sure you have enabled reload on device / emulator :

• To enable reload on emulator: press "ctrl+M / Cmd + M / R,R(Press R Twise)"
• To enable reload on real device : Shake your phone : it will show popup to reload.
