Trace Method Execution

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.

Usage examples:

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

Will generate those log entries:

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

Equivalent boilerplate code :

public void doWork() {
    if (Log.isLoggable("TracedMethodActivity", Log.INFO)) {
        long start = System.currentTimeMillis();
        Log.i("TracedMethodActivity", "Entering [void doWork() ]");
    }
    try {
        // ... Do Work ...
    } finally {
        if (Log.isLoggable("TracedMethodActivity", Log.INFO)) {
            long duration = (System.currentTimeMillis()-start);
            Log.i("TracedMethodActivity", ("Exiting [void doWork() ], duration in ms: "+ duration));
        }
    }
}

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
