Public methods

addDeviceMonitor

public abstract void addDeviceMonitor (IDeviceMonitor mon)

Adds a IDeviceMonitor

Parameters
`mon`	`IDeviceMonitor`

addFastbootListener

public abstract void addFastbootListener (IDeviceManager.IFastbootListener listener)

Informs the manager that a listener is interested in fastboot state changes.

Currently a IDeviceManager will only monitor devices in fastboot if there are one or more active listeners.

TODO: this is a bit of a hack - find a better solution

allocateDevice

public abstract ITestDevice allocateDevice (IDeviceSelection options, 
                boolean isTemporary)

Request a device for testing that meets certain criteria.

Parameters
`options`	`IDeviceSelection`: the `IDeviceSelection` the device should meet.
`isTemporary`	`boolean`: whether or not a temporary NullDevice should be created.

Returns
`ITestDevice`	a `ITestDevice` for testing, or `null` if one is not available

allocateDevice

public abstract ITestDevice allocateDevice (IDeviceSelection options)

Request a device for testing that meets certain criteria.

Parameters

Returns
`ITestDevice`	a `ITestDevice` for testing, or `null` if one is not available

connectToTcpDevice

public abstract ITestDevice connectToTcpDevice (String ipAndPort)

Connect to a device with adb-over-tcp

This method allocates a new device, which should eventually be freed via disconnectFromTcpDevice(com.android.tradefed.device.ITestDevice)

The returned ITestDevice will be online, but may not be responsive.

Note that performing action such as a reboot on a tcp connected device, will sever the tcp connection to the device, and result in a DeviceNotAvailableException

Returns
`ITestDevice`	the `ITestDevice` or `null` if a tcp connection could not be formed

disconnectFromTcpDevice

Returns
`boolean`	`true` if switch to usb mode was successful

displayDevicesInfo

public abstract void displayDevicesInfo (PrintWriter printWriter, 
                boolean includeStub)

Output a user-friendly description containing list of known devices, their state, and values for commonly used IDeviceSelection options.

Parameters
`printWriter`	`PrintWriter`: the `ERROR(/PrintWriter)` to output the description to
`includeStub`	`boolean`: Whether or not to display stub devices too.

forceAllocateDevice
