Android Emulator Hosts Setup

In order to reach the private hostname "frpariticsd" you have to update the /etch/hosts file into the Android filesystem.

  1. Using Android Studio, create a non-Play Store emulator
  2. Update PATH system variable including "emulator" and "adb" executables from Android SDK.
    • For OSX users:
      1. Run command "sudo nano /etc/paths"
      2. Append the path to the "emulator" command (i.e. /Users/YOUR_USERNAME/Library/Android/sdk/emulator)
      3. Append the path to the "adb" command (i.e. /Users/YOUR_USERNAME/Library/Android/sdk/platform-tools)
    • For Windows users:
      1. export ANDROID_HOME="/Users/YOUR_USERNAME/Library/Android/sdk"
      2. export PATH=$ANDROID_HOME/emulator:$ANDROID_HOME/tools:$PATH
  3. Run command "emulator -list-avds" to see the list of available emulators.
  4. Run command for writable system feature "emulator -avd YOUR_AVD_NAME -writable-system -no-snapshot-load -no-cache"
  5. Fetch the hosts file running "adb pull /etc/hosts"
  6. Edit the file and append line "10.24.219.91 frpariticsd"
  7. Run the following commands in order to run as root and to remount partition:
    • adb devices #you should see your devices
    • adb root
    • adb shell avbctl disable-verification
    • adb reboot (it may take a minute)
    • adb root
    • adb remount
  8. After remount push the new hosts file to the emulator filesystem, running command "adb push hosts /etc/hosts"
  9. Open browser and navigate to "frpariticsd:1200" to check everything is fine
