MigrateToAndroidX

Python Script to automatically migrate old imports in a React-Native project to AndroidX imports

What does it do?

• Uses the bindings file provided by Android
• Looks at all the node_modules java files and searches for the old bindings (Usually of the form android.support.*) and replaces with the new AndroidX imports(Of the form androidx.*)
• Currently, I'm only looking for a sublist of imports (that is used by most react-native libraries) and replacing them. The sublist of imports are below:-

1. android.support.annotation.**
2. android.support.annotation.RequiresPermission.**
3. android.support.design.**
4. android.support.v4.**

Usage

python3 migrateToAndroidX.py --node_modules <path>

Example

If your path is ~/projects/rnProject/node_modules/ python3 migrateToAndroidX.py --node_modules ~/projects/rnProject/node_modules/

How to make this script run automatically after npm install

It might be beneficial to run the script after all node_modules are installed. For this, we can use postinstall hook of npm In your package.json, you can add a new script,

"scripts":{
  ... 
  "postinstall":"python3 migrateToAndroidX.py --node_modules <path>"
}
