To configure an HTTP proxy in BlueStacks App Player on Windows, for example to use Fiddler or a similar tool to inspect and debug HTTP traffic, use the ADB interface for BlueStacks.
First, launch BlueStacks App Player.
Open Windows Terminal and navigate to the C:\Program Files\BlueStacks_nxt directory.
Confirm that the app player is visible by running .\HD-Adb.exe devices. You should see the emulator device attached.
Use the following command to configure the HTTP proxy, replacing the IP address and port number as appropriate to your setup:
.\HD-Adb.exe shell settings put global http_proxy 192.168.1.1:1234
You may need to restart the app player for the setting to take effect.
Run the following commands to remove the proxy configuration:
.\HD-Adb.exe shell settings delete global global_http_proxy_host
.\HD-Adb.exe shell settings delete global global_http_proxy_port
.\HD-Adb.exe shell settings delete global http_proxy
You may need to restart the app player for the setting to take effect.
