Change package name for Android in React Native

I’ve renamed the project’ subfolder from: “android/app/src/main/java/MY/APP/OLD_ID/” to: “android/app/src/main/java/MY/APP/NEW_ID/

Then manually switched the old and new package ids:

In: android/app/src/main/java/MY/APP/NEW_ID/MainActivity.java:

package MY.APP.NEW_ID;

In android/app/src/main/java/MY/APP/NEW_ID/MainApplication.java:

package MY.APP.NEW_ID;

In android/app/src/main/AndroidManifest.xml:

package="MY.APP.NEW_ID"

And in android/app/build.gradle:

applicationId "MY.APP.NEW_ID"

In android/app/BUCK:

android_build_config(
  package="MY.APP.NEW_ID"
)
android_resource(
  package="MY.APP.NEW_ID"
)

Gradle’ cleaning in the end (in /android folder):

./gradlew clean

No emulators found as an output of emulator -list-avds

I got this error when running react-native app by running the command: npx react-native run-android

error Failed to launch emulator. Reason: No emulators found as an output of `emulator -list-avds`.
warn Please launch an emulator manually or connect a device. Otherwise app may fail to launch

Checking adb device running and the command not found.

adb devices
zsh: command not found: adb

The solution for Mac user is to edit .zshrc by add following:

# fix adb command not found
alias adb='/Users/softmastx/Library/Android/sdk/platform-tools/adb'

# fix No emulators found
export ANDROID_HOME=$HOME/Library/Android/sdk
export PATH=$PATH:$ANDROID_HOME/emulator
export PATH=$PATH:$ANDROID_HOME/tools
export PATH=$PATH:$ANDROID_HOME/tools/bin
export PATH=$PATH:$ANDROID_HOME/platform-tools

Save it and don’t forget to restart zsh for the changes to take effect!

source ~/.zshrc
