after update of my android package name change DataBindingUtil.setContentView returns null

  1. Build > Clean Project

  2. go to your Build.gradle (Module) and disable databinding:

    android { dataBinding { enabled = false } }

  3. File > Sync Project with Gradle Files

  4. Build > Rebuild Project (no surprise: you'll get a ton of error messages)

  5. Now enable databinding again:

    android { dataBinding { enabled = true } }

  6. File > Sync Project with Gradle Files

  7. Build > Rebuild Project

How to Debug Android TV App using IP

How to Connect Android TV to Your PC Using ADB Normally, we use a USB cable to connect a PC with an Android. Since this is not feasible with Android TVs, manufacturers allow you to  set up ADB wirelessly . To do that: On your Android TV, go to  Settings > Device Preferences > About > Status  and note down the  IP address . Open the command prompt on your PC and enter the command  adb connect <the IP address> . tiny adb on desktop enter ip address You will get a prompt on your Android TV asking you to authorize a connection to the computer.
