Modifying AndroidManifest.xml

This feature allows you to modify the AndroidManifest.xml file of your Expo project. You can use it to add, remove, or change elements in the manifest file.

const { withAndroidManifest } = require('@expo/config-plugins');

module.exports = function withCustomAndroidManifest(config) {
  return withAndroidManifest(config, async config => {
    const androidManifest = config.modResults;
    // Modify the AndroidManifest.xml here
    return config;
  });
};

Modifying Info.plist

This feature allows you to modify the Info.plist file of your Expo project. You can use it to add, remove, or change properties in the plist file.

const { withInfoPlist } = require('@expo/config-plugins');

module.exports = function withCustomInfoPlist(config) {
  return withInfoPlist(config, config => {
    const infoPlist = config.modResults;
    // Modify the Info.plist here
    return config;
  });
};

Adding custom native code

This feature allows you to add or modify custom native code in your Expo project. You can use it to include custom Objective-C, Swift, Java, or Kotlin code in your project.

const { withDangerousMod } = require('@expo/config-plugins');
const fs = require('fs');
const path = require('path');

module.exports = function withCustomNativeCode(config) {
  return withDangerousMod(config, [
    'ios',
    async config => {
      const filePath = path.join(config.modRequest.platformProjectRoot, 'path/to/your/file.m');
      const fileContent = fs.readFileSync(filePath, 'utf-8');
      // Modify the native code here
      fs.writeFileSync(filePath, fileContent);
      return config;
    }
  ]);
};
