Trace Method Execution - WonderCsabo/androidannotations GitHub Wiki

Since AndroidAnnotations 2.2

The @Trace annotation allows you to trace the execution of a method by writing log entries.

The method must not be private.

You must enable tracing in the processing options, otherwise tracing code will not be generated!

Usage examples:

@Trace
void doWork() {
    // ... Do Work ...
}

@Trace
boolean doMoreWork(String someString) {
    // ... Do more Work ...
}

Will generate the following log entries for doWork():

I/TracedMethodActivity(  302): Entering [void doWork() ]
I/TracedMethodActivity(  302): Exiting [void doWork() ], duration in ms: 1002

And this log entries for doMoreWork():

Since AndroidAnnotations 3.1

I/TracedMethodActivity(  302): Entering [boolean doMoreWork(someString = Hello World)]
I/TracedMethodActivity(  302): Exiting [boolean doMoreWork(String) returning: true], duration in ms: 651

Customization

Since AndroidAnnotations 2.2 You can also specify the tag and the level of the log message:

@Trace(tag="CustomTag", level=Log.WARN)
void doWork() {
    // ... Do Work ...
}

W/CustomTag(  533): Entering [void doWork() ]
W/CustomTag(  533): Exiting [void doWork() ], duration in ms: 1001
