react-native run-android builds an old version of the code onto device

问题

This occurs in both production and dev builds. I can connect to the dev server, reload, and the new code is built and runs on the device.

Step-by-step of what I have tried:

1. Modify code.

2. Re-bundle:

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

3. ./gradlew clean

4. react-native run-android - Builds old version

5. react-native run-android --variant=release - Builds old version

Is there any way to completely wipe the android build and build from scratch? My gut tells me that run-android is not performing a full clean build.

回答1:

1. Delete files inside directory android/app/src/main/assets.
2. run $ 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
3. $ react-native run-android
