@UnstableApi
class Log

Wrapper around android.util.Log which allows to set the log level and to specify a custom log output.

Summary

Nested types
`@Documented @Retention(value = RetentionPolicy.SOURCE) @Target(value = TYPE_USE) @IntDef(value = ) annotation Log.LogLevel` Log level for ExoPlayer logcat logging.

Constants
`const Int`	`LOG_LEVEL_ALL = 0` Log level to log all messages.
`const Int`	`LOG_LEVEL_ERROR = 3` Log level to only log error messages.
`const Int`	`LOG_LEVEL_INFO = 1` Log level to only log informative, warning and error messages.

LOG_LEVEL_OFF

const val LOG_LEVEL_OFF = 2147483647: Int

Public functions

appendThrowableString

@Pure
java-static fun appendThrowableString(message: String!, throwable: Throwable?): String!

Appends the result of getThrowableString (if non-empty) to message.

d

@Pure
java-static fun d(tag: @Size(max = 23) String!, message: String!): Unit

Logs a debug-level message.

Parameters
`tag: @Size(max = 23) String!`	The tag of the message.
`message: String!`	The message.

d

@Pure
java-static fun d(tag: @Size(max = 23) String!, message: String!, throwable: Throwable?): Unit

Logs a debug-level message with an optional associated Throwable.

Parameters
`tag: @Size(max = 23) String!`	The tag of the message.
`message: String!`	The message.
`throwable: Throwable?`	The `Throwable` associated with the message, or null if not specified.

e

@Pure
java-static fun e(tag: @Size(max = 23) String!, message: String!): Unit

Logs an error-level message.

Parameters
`tag: @Size(max = 23) String!`	The tag of the message.
`message: String!`	The message.

e

@Pure
java-static fun e(tag: @Size(max = 23) String!, message: String!, throwable: Throwable?): Unit

Logs an error-level message with an optional associated Throwable.

Parameters
`tag: @Size(max = 23) String!`	The tag of the message.
`message: String!`	The message.
`throwable: Throwable?`	The `Throwable` associated with the message, or null if not specified.

getThrowableString

@Pure
java-static fun getThrowableString(throwable: Throwable?): String?

Returns a string representation of a Throwable suitable for logging, taking into account whether setLogStackTraces stack trace logging} is enabled.

Stack trace logging may be unconditionally suppressed for some expected failure modes (e.g., Throwables that are expected if the device doesn't have network connectivity) to avoid log spam.

Parameters
`throwable: Throwable?`	The `Throwable`.

Returns
`String?`	The string representation of the `Throwable`, or null if `throwable` is null.

i

@Pure
java-static fun i(tag: @Size(max = 23) String!, message: String!): Unit

Logs an information-level message.

Parameters
`tag: @Size(max = 23) String!`	The tag of the message.
`message: String!`	The message.

i

@Pure
java-static fun i(tag: @Size(max = 23) String!, message: String!, throwable: Throwable?): Unit

Logs an information-level message with an optional associated Throwable.

Parameters
`tag: @Size(max = 23) String!`	The tag of the message.
`message: String!`	The message.
`throwable: Throwable?`	The `Throwable` associated with the message, or null if not specified.

setLogStackTraces

java-static fun setLogStackTraces(logStackTraces: Boolean): Unit

Sets whether stack traces of Throwables will be logged to logcat. Stack trace logging is enabled by default.

Parameters
`logStackTraces: Boolean`	Whether stack traces will be logged.

setLogger

java-static fun setLogger(logger: Log.Logger!): Unit

Sets a custom Logger as the output.

Parameters
`logger: Log.Logger!`	The `Logger`.

w

@Pure
java-static fun w(tag: @Size(max = 23) String!, message: String!): Unit

Logs a warning-level message.

Parameters
`tag: @Size(max = 23) String!`	The tag of the message.
`message: String!`	The message.

w

@Pure
java-static fun w(tag: @Size(max = 23) String!, message: String!, throwable: Throwable?): Unit

Logs a warning-level message with an optional associated Throwable..

Parameters
`tag: @Size(max = 23) String!`	The tag of the message.
`message: String!`	The message.
`throwable: Throwable?`	The `Throwable` associated with the message, or null if not specified.
