Implementation Details

The plugin uses Android intents to communicate with Google Play Store:

  • Intent action for inline install overlay

Use Cases

  • Cross-promotion: Drive installs for partner applications
  • Feature unlocking: Install additional modules or extensions

Best Practices

  • Use referrer tracking to measure conversion rates
  • Handle installation errors gracefully
  • Respect user choice if they decline installation

Limitations

  • Android-only functionality
  • Requires Google Play Services
  • Only works with apps qualifying for Premium Growth Tools
  • Subject to Google Play Store policies and availability
