Parameters
deviceFilePath String: The absolute path of the file on the device.

public abstract String getFastbootProductVariant ()

Convenience method to get the product type of this device when its in fastboot mode.

This method should only be used if device should be in fastboot. Its a bit safer variant than the generic getProductType() method in this case, because ITestDevice will know to recover device into fastboot if device is in incorrect state or is unresponsive.

Returns
String the String product type name or null if it cannot be determined
Throws
DeviceNotAvailableException if connection with device is lost and cannot be recovered.

Returns
IFileEntry the IFileEntry or null if file at given path cannot be found
Throws
DeviceNotAvailableException

Returns
IDevice the IDevice

getLastExpectedRebootTimeMillis

public abstract long getLastExpectedRebootTimeMillis ()

Returns the last time Tradefed APIs triggered a reboot in milliseconds since EPOCH as returned by System.currentTimeMillis().
