Inherited methods

From class


        
          java.lang.Object

`Object`	`clone()` Creates and returns a copy of this object.
`boolean`	`equals(Object obj)` Indicates whether some other object is "equal to" this one.
`void`	`finalize()` Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
`final Class<?>`	`getClass()` Returns the runtime class of this `Object`.
`int`	`hashCode()` Returns a hash code value for the object.
`final void`	`notify()` Wakes up a single thread that is waiting on this object's monitor.
`final void`	`notifyAll()` Wakes up all threads that are waiting on this object's monitor.
`String`	`toString()` Returns a string representation of the object.
`final void`	`wait(long timeoutMillis, int nanos)` Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.
`final void`	`wait(long timeoutMillis)` Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.
`final void`	`wait()` Causes the current thread to wait until it is awakened, typically by being notified or interrupted.

Constants

CATEGORIES_ALL

Added in API level 28

public static final int CATEGORIES_ALL

Predefined set of categories, includes all categories enabled by default in chromium. Use with caution: this setting may produce large trace output.

Constant Value: 1 (0x00000001)

CATEGORIES_ANDROID_WEBVIEW

Added in API level 28

public static final int CATEGORIES_ANDROID_WEBVIEW

Predefined set of categories typically useful for analyzing WebViews. Typically includes "android_webview" and "Java" categories.

Constant Value: 2 (0x00000002)

CATEGORIES_FRAME_VIEWER

Added in API level 28

public static final int CATEGORIES_FRAME_VIEWER

Predefined set of categories for studying difficult rendering performance problems. Typically includes "blink", "compositor", "gpu", "renderer.scheduler", "v8" and some other compositor categories which are disabled by default.

Constant Value: 64 (0x00000040)

CATEGORIES_INPUT_LATENCY

Added in API level 28

public static final int CATEGORIES_INPUT_LATENCY

Predefined set of categories for analyzing input latency issues. Typically includes "input", "renderer.scheduler" categories.

Constant Value: 8 (0x00000008)

CATEGORIES_JAVASCRIPT_AND_RENDERING

Added in API level 28

public static final int CATEGORIES_JAVASCRIPT_AND_RENDERING

Predefined set of categories for analyzing javascript and rendering issues. Typically includes "blink", "compositor", "gpu", "renderer.scheduler" and "v8" categories.

Constant Value: 32 (0x00000020)

CATEGORIES_NONE

Added in API level 28

public static final int CATEGORIES_NONE

Indicates that there are no predefined categories.

Constant Value: 0 (0x00000000)

CATEGORIES_RENDERING

Added in API level 28

public static final int CATEGORIES_RENDERING

Predefined set of categories for analyzing rendering issues. Typically includes "blink", "compositor" and "gpu" categories.

Constant Value: 16 (0x00000010)

CATEGORIES_WEB_DEVELOPER

Added in API level 28

public static final int CATEGORIES_WEB_DEVELOPER

Predefined set of categories typically useful for web developers. Typically includes "blink", "compositor", "renderer.scheduler" and "v8" categories.

Constant Value: 4 (0x00000004)

RECORD_CONTINUOUSLY

Added in API level 28

public static final int RECORD_CONTINUOUSLY

Record trace events continuously using an internal ring buffer. Default tracing mode. Overwrites old events if they exceed buffer capacity. Uses less memory than the RECORD_UNTIL_FULL mode. Depending on the implementation typically allows up to 64k events to be stored.

Constant Value: 1 (0x00000001)

RECORD_UNTIL_FULL

Added in API level 28

public static final int RECORD_UNTIL_FULL

Record trace events until the internal tracing buffer is full. Typically the buffer memory usage is larger than RECORD_CONTINUOUSLY. Depending on the implementation typically allows up to 256k events to be stored.

Constant Value: 0 (0x00000000)

Public methods

Returns a bitmask of the predefined category sets of this configuration.

Returns
`int`	Bitmask of predefined category sets. Value is either `0` or a combination of `CATEGORIES_NONE`, `CATEGORIES_ALL`, `CATEGORIES_ANDROID_WEBVIEW`, `CATEGORIES_WEB_DEVELOPER`, `CATEGORIES_INPUT_LATENCY`, `CATEGORIES_RENDERING`, `CATEGORIES_JAVASCRIPT_AND_RENDERING`, and `CATEGORIES_FRAME_VIEWER`
