Public methods

recoverDevice

public void recoverDevice (IDeviceStateMonitor monitor, 
                boolean recoverUntilOnline)

Attempt to recover the given device that can no longer be communicated with.

Method should block and only return when device is in requested state.

Parameters
monitor IDeviceStateMonitor: the IDeviceStateMonitor to use.

recoverUntilOnline boolean: if true, method should return as soon as device is online on adb. If false, method should block until device is fully available for testing (ie IDeviceStateMonitor.waitForDeviceAvailable() succeeds.

Throws
DeviceNotAvailableException

recoverDeviceBootloader

public void recoverDeviceBootloader (IDeviceStateMonitor monitor)

Attempt to recover the given unresponsive device in bootloader mode.

Parameters
monitor IDeviceStateMonitor: the IDeviceStateMonitor to use.

Throws
DeviceNotAvailableException

recoverDeviceRecovery

public void recoverDeviceRecovery (IDeviceStateMonitor monitor)

Attempt to recover the given unresponsive device in recovery mode.

Parameters
monitor IDeviceStateMonitor: the IDeviceStateMonitor to use.

Throws
DeviceNotAvailableException

setFastbootPath

public void setFastbootPath (String fastbootPath)

Sets the path to the fastboot binary to be used.

Parameters
fastbootPath String: a String defining the path to the fastboot binary.

Protected methods

checkMinBatteryLevel

protected void checkMinBatteryLevel (IDevice device)

Checks if device battery level meets min requirement

Throws
DeviceNotAvailableException if battery level cannot be read or lower than min

getRunUtil

protected IRunUtil getRunUtil ()

Get the RunUtil instance to use.

Exposed for unit testing.

Returns
