How to Sideload Apps and Use Developer Mode on WearOS

Here’s how to enable developer mode and sideload apps on your WearOS watch.

How to Enable Developer Mode

1. Go to Settings > Other > About watch > Other version info.
2. Tap Build number seven times until you see the message, "You are now a developer!"
3. Enable the ADB Debugging toggle.
4. For WearOS 4 and newer, enable Wireless debugging in Developer options.

Sideloading Methods

• Wear Installer 2 (Recommended): This app allows you to transfer APKs from your phone to your watch via ADB.
• Apps2Fire: This app allows you to sideload all of your phone apps or specific APKs.
• Bugjaeger: This is a third-party app that simplifies the pairing and APK installation process.
• Direct ADB Commands: This method requires the Android SDK Platform Tools and allows you to install APKs manually from the command line.

Common Troubleshooting

• Connection Issues: If you see a "Could not connect to watch" error, check your Wi-Fi and Bluetooth connectivity.
• APK Compatibility: If you see a "Watch APK not found" error, the app may not have a watch component.
• Architecture Errors: If you see an "INSTALL_FAILED_NO_MATCHING_ABIS" error, there is an APK architecture mismatch.
• Security: Turn off ADB debugging when you're finished for security and to preserve battery life.
