Description:

Improve support for newer devices using the Python ADB implementation (as opposed to the ADB server approach).

Related issue (if applicable): This fixes a bug where the ADB connection attempt would fail but adb-shell would incorrectly report to androidtv that the connection was available, and when androidtv would send an ADB command it would cause an exception. With this fix in place, if the ADB connection attempt fails then a PlatformNotReady exception will be raised, which is the desired behavior.

This also applies to the case that a re-connect attempt fails, which could occur during a reboot of the device.

Any chance this bug fix could be included in 0.100?
