public class LogcatReceiver
extends Object implements ILogcatReceiver

java.lang.Object
↳	com.android.tradefed.device.LogcatReceiver

Class that collects logcat in background. Continues to capture logcat even if device goes offline then online.

Summary

Public constructors
`LogcatReceiver(ITestDevice device, String logcatCmd, long maxFileSize, int logStartDelay)` Creates an instance with any specified logcat command
`LogcatReceiver(ITestDevice device, long maxFileSize, int logStartDelay)` Creates an instance with default logcat 'threadtime' format

Public methods
`void`	`clear()`
`static String`	`getDefaultLogcatCmd(ITestDevice device)` Get the default logcat command, only append uid format if api level > 24.
`InputStreamSource`	`getLogcatData(int maxBytes, int offset)` Returns the current logcat buffer given an offset.
`InputStreamSource`	`getLogcatData(int maxBytes)`
`InputStreamSource`	`getLogcatData()`
`void`	`start()`
`void`	`stop()`

public LogcatReceiver (ITestDevice device, 
                String logcatCmd, 
                long maxFileSize, 
                int logStartDelay)

Creates an instance with any specified logcat command

Parameters
`device`	`ITestDevice`: the device to start logcat on
`logcatCmd`	`String`: the logcat command to run (including 'logcat' part), see details on available options in logcat help message
`maxFileSize`	`long`: maximum file size, earlier lines will be discarded once size is reached
`logStartDelay`	`int`: the delay to wait after the device becomes online
