Functions
ATrace_beginAsyncSection
Declared inandroid/trace.h
void ATrace_beginAsyncSection( const char *sectionName, int32_t cookie )
Writes a trace message to indicate that a given section of code has begun.
Must be followed by a call to ATrace_endAsyncSection with the same methodName and cookie. Unlike ATrace_beginSection and ATrace_endSection, asynchronous events do not need to be nested. The name and cookie used to begin an event must be used to end it.
Available since API level 29.

Parameters |
|
ATrace_beginSection
Declared inandroid/trace.h
void ATrace_beginSection( const char *sectionName )
Writes a tracing message to indicate that the given section of code has begun.
This call must be followed by a corresponding call to ATrace_endSection on the same thread.
Note: At this time the vertical bar character '|' and newline character '\n' are used internally by the tracing mechanism. If sectionName
contains these characters they will be replaced with a space character in the trace.
Available since API level 23.
ATrace_endAsyncSection
Declared inandroid/trace.h
void ATrace_endAsyncSection( const char *sectionName, int32_t cookie )
Writes a trace message to indicate that the current method has ended.
Must be called exactly once for each call to ATrace_beginAsyncSection using the same name and cookie.
Available since API level 29.

Parameters |
|
ATrace_endSection
Declared inandroid/trace.h
void ATrace_endSection()
Writes a tracing message to indicate that a given section of code has ended.
This call must be preceeded by a corresponding call to ATrace_beginSection on the same thread. Calling this method will mark the end of the most recently begun section of code, so care must be taken to ensure that ATrace_beginSection/ATrace_endSection pairs are properly nested and called from the same thread.
Available since API level 23.
ATrace_isEnabled
Declared inandroid/trace.h
bool ATrace_isEnabled()
Returns true if tracing is enabled.
Use this to avoid expensive computation only necessary when tracing is enabled.
Available since API level 23.
ATrace_setCounter
Declared inandroid/trace.h
void ATrace_setCounter( const char *counterName, int64_t counterValue )
Writes trace message to indicate the value of a given counter.
Available since API level 29.
