Issue ID




Entering Play mode for the first time also launches adb.exe which locks Unity editor when closing it



Android development kit is required for reproduction.

Steps to reproduce:
1. Open any project
2. Start entering play mode.
3. adb.exe process will be created and will remain running.
4. Once play mode starts running adb.exe remains running as independent process.
5. If adb.exe is killed, it will not be launched again.

Reproducible with any platform editor mode.

The issue is fixed in Unity 4.3.7 Patch 1 version.

    Occurring in 5.3.4f1.

    It also prevents the game shutting down correctly in Steam, as Steam still considers adb.exe to be a dependent process and therefore assumes the game is still running. Big problem for me.

    Seems to be fixed now if you update using the Android SDK.
