Constants

CATEGORIES_ALL

Added in API level 28
static val CATEGORIES_ALL: Int

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

Value: 1

CATEGORIES_ANDROID_WEBVIEW

Added in API level 28
static val CATEGORIES_ANDROID_WEBVIEW: Int

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

Value: 2

CATEGORIES_FRAME_VIEWER

Added in API level 28
static val CATEGORIES_FRAME_VIEWER: Int

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.

Value: 64

CATEGORIES_INPUT_LATENCY

Added in API level 28
static val CATEGORIES_INPUT_LATENCY: Int

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

Value: 8

CATEGORIES_JAVASCRIPT_AND_RENDERING

Added in API level 28
static val CATEGORIES_JAVASCRIPT_AND_RENDERING: Int

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

Value: 32

CATEGORIES_NONE

Added in API level 28
static val CATEGORIES_NONE: Int

Indicates that there are no predefined categories.

Value: 0

CATEGORIES_RENDERING

Added in API level 28
static val CATEGORIES_RENDERING: Int

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

Value: 16

CATEGORIES_WEB_DEVELOPER

Added in API level 28
static val CATEGORIES_WEB_DEVELOPER: Int

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

Value: 4

RECORD_CONTINUOUSLY

Added in API level 28
static val RECORD_CONTINUOUSLY: Int

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.

Value: 1

RECORD_UNTIL_FULL

Added in API level 28
static val RECORD_UNTIL_FULL: Int

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.

Value: 0
