android.util.TimingLogger
A utility class to help log timings splits throughout a method call.
Typical usage is:
TimingLogger timings = new TimingLogger(TAG, "methodA");
... do some work A ...
timings.addSplit("work A");
... do some work B ...
timings.addSplit("work B");
... do some work C ...
timings.addSplit("work C");
timings.dumpToLog();
The dumpToLog call would add the following to the log:
D/TAG ( 3459): methodA: begin
D/TAG ( 3459): methodA: 9 ms, work A
D/TAG ( 3459): methodA: 1 ms, work B
D/TAG ( 3459): methodA: 6 ms, work C
D/TAG ( 3459): methodA: end, 16 ms

Details
Public Constructors
public
TimingLogger(String tag, String label)
Create and initialize a TimingLogger object that will log using
the specific tag. If the Log.isLoggable is not enabled to at
least the Log.VERBOSE level for that tag at creation time then
the addSplit and dumpToLog call will do nothing.
Parameters
tag
| the log tag to use while logging the timings |
label
| a string to be displayed with each log
|
Public Methods
public
void
addSplit(String splitLabel)
Add a split for the current time, labeled with splitLabel. If
Log.isLoggable was not enabled to at least the Log.VERBOSE for
the specified tag at construction or reset() time then this
call does nothing.
Parameters
splitLabel
| a label to associate with this split.
|
public
void
dumpToLog()
Dumps the timings to the log using Log.d(). If Log.isLoggable was
not enabled to at least the Log.VERBOSE for the specified tag at
construction or reset() time then this call does nothing.
public
void
reset(String tag, String label)
Clear and initialize a TimingLogger object that will log using
the specific tag. If the Log.isLoggable is not enabled to at
least the Log.VERBOSE level for that tag at creation time then
the addSplit and dumpToLog call will do nothing.
Parameters
tag
| the log tag to use while logging the timings |
label
| a string to be displayed with each log
|
public
void
reset()
Clear and initialize a TimingLogger object that will log using
the tag and label that was specified previously, either via
the constructor or a call to reset(tag, label). If the
Log.isLoggable is not enabled to at least the Log.VERBOSE
level for that tag at creation time then the addSplit and
dumpToLog call will do nothing.
