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)
