Constants

UNKNOWN_API_LEVEL

public static final int UNKNOWN_API_LEVEL

Default value when API Level cannot be detected

Constant Value: -1 (0xffffffff)

Public methods

clearLogcat

public abstract void clearLogcat ()

Deletes any accumulated logcat data.

This is useful for cases when you want to ensure getLogcat() only returns log data produced after a certain point (such as after flashing a new device build, etc).

disableAdbRoot

public abstract boolean disableAdbRoot ()

Turns off adb root.

Disabling adb root may cause device to disconnect from adb. This method will block until device is available.

Returns
`boolean`	`true` if successful.

Throws
`DeviceNotAvailableException`	if connection with device is lost and cannot be recovered.

doesFileExist

public abstract boolean doesFileExist (String deviceFilePath)

Helper method to determine if file on device exists.

Parameters
`deviceFilePath`	`String`: the absolute path of file on device to check

Returns
`boolean`	`true` if file exists, `false` otherwise.

Throws
`DeviceNotAvailableException`	if connection with device is lost and cannot be recovered.

enableAdbRoot

public abstract boolean enableAdbRoot ()

Turns on adb root. If the "enable-root" setting is "false", will log a message and return without enabling root.

Enabling adb root may cause device to disconnect from adb. This method will block until device is available.

Returns
`boolean`	`true` if successful.

Throws
`DeviceNotAvailableException`	if connection with device is lost and cannot be recovered.

encryptDevice

public abstract boolean encryptDevice (boolean inplace)

Encrypts the device.

Encrypting the device may be done inplace or with a wipe. Inplace encryption will not wipe any data on the device but normally takes a couple orders of magnitude longer than the wipe.

Parameters
`inplace`	`boolean`: if the encryption process should take inplace and the device should not be wiped.

Returns
`boolean`	`true` if successful.

Throws
`DeviceNotAvailableException`	if device is not available after reboot.

Parameters
`partition`	`String`: the partition to wipe

Returns
`CommandResult`	the CommandResult containing output of command

Throws

`int`	an integer indicating the API Level of device

Throws
`DeviceNotAvailableException`

getBasebandVersion

public abstract String getBasebandVersion ()

Convenience method to get baseband (radio) version of this device. Getting the radio version is device specific, so it might not return the correct information for all devices. This method relies on the gsm.version.baseband propery to return the correct version information. This is not accurate for some CDMA devices and the version returned here might not match the version reported from fastboot and might not return the version for the CDMA radio. TL;DR this method only reports accurate version if the gsm.version.baseband property is the same as the version returned by fastboot getvar version-baseband.

Throws
`DeviceNotAvailableException`	if the connection with the device is lost and cannot be recovered.

getBootloaderVersion

Throws
`DeviceNotAvailableException`	if connection with device is lost and cannot be recovered.

Returns
`InputStreamSource`	An `InputStreamSource` which will produce the bugreport contents on demand. In case of failure, the `InputStreamSource` will produce an empty `InputStream`.

getBugreportz

public abstract InputStreamSource getBugreportz ()

Retrieves a bugreportz from the device. Zip format bugreport contains the main bugreport and other log files that are useful for debugging.

Only supported for 'adb version' > 1.0.36

Returns
`InputStreamSource`	a `InputStreamSource` of the zip file containing the bugreportz, return null in case of failure.

getBuildAlias

public abstract String getFastbootProductType ()

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.

Throws
`DeviceNotAvailableException`

getIDevice

public abstract IDevice getIDevice ()

Returns
`IDevice`	the `IDevice`

getLogcat

public abstract InputStreamSource getLogcat ()

Grabs a snapshot stream of the logcat data.

Works in two modes:

If the logcat is currently being captured in the background, will return up to TestDeviceOptions.getMaxLogcatDataSize() bytes of the current contents of the background logcat capture

Otherwise, will return a static dump of the logcat data if device is currently responding

Returns
`InputStreamSource`

getLogcat

public abstract InputStreamSource getLogcat (int maxBytes)

Grabs a snapshot stream of the last maxBytes of captured logcat data.

Useful for cases when you want to capture frequent snapshots of the captured logcat data without incurring the potentially big disk space penalty of getting the entire getLogcat() snapshot.

Parameters
`maxBytes`	`int`: the maximum amount of data to return. Should be an amount that can comfortably fit in memory

Returns
`InputStreamSource`

getLogcatDump

public abstract InputStreamSource getLogcatDump ()

Get a dump of the current logcat for device. Unlike getLogcat(), this method will always return a static dump of the logcat.

Has the disadvantage that nothing will be returned if device is not reachable.

Returns
`InputStreamSource`	a `InputStreamSource` of the logcat data. An empty stream is returned if fail to capture logcat data.
