Capture HTTPS from a React Native Expo app on the iOS Simulator and Android Emulator

1. React Native - iOS​

  • If you're using React Native for the iOS app, follow the iOS guides. There is no difference from a native iOS app.
  • Works with Expo or the Metro bundler

iOS DeviceCapture iPhone and iPad HTTP/HTTPS traffic with Proxyman on your Mac: set the Wi-Fi proxy, then install and trust the Proxyman certificate on the device.

iOS SimulatorCapture iOS Simulator HTTP/HTTPS traffic with Proxyman on macOS, using automatic certificate setup, manual installation, and missing-traffic checks.

2. React Native - Android​

warning

Make sure you've followed all steps in the guide, especially the 5th step, where you add the res/xml/network_security_config.xml and AndroidManifest.xml

Otherwise, Proxyman cannot decrypt the SSL connection.

3. Troubleshooting - Android​

3.1 Metro bundle errors​

After you set the HTTP Proxy on your Android device to Proxyman, you might get the following error, because the Metro bundler cannot connect to its local server.

Metro bundle errors

To fix it:

Android Emulator​

  1. Open Proxyman -> Certificate menu -> Install Certificate on Android -> Emulators… -> Click "Revert All Changes"
  2. Open the Android Emulator -> Settings app -> Network -> Wi-Fi -> Open the proxy settings
  3. Set the HTTP Proxy manually with the Proxyman IP & Port. If you don't know the IP & Port, open the Certificate menu -> Install Certificate on Android -> Physical Devices… and find the Server IP & Port in step 2.
  4. Before saving, enter localhost in the bypass proxy list ✅

Android Wi-Fi proxy settings with the Proxyman IP and port and localhost in the bypass proxy list

  1. Done
  2. The The Bridge Was shutdown warning and the Metro bundle errors are gone ✅

Android Physical Device​

  1. Open the Android physical device -> Settings app -> Network -> Wi-Fi -> Open the proxy settings
  2. Set the HTTP Proxy manually with the Proxyman IP & Port. If you don't know the IP & Port, open the Certificate menu -> Install Certificate on Android -> Physical Devices… and find the Server IP & Port in step 2.
  3. Before saving, enter your IP in the bypass proxy list ✅
