Why does activity manager shows starting intent message?

Question

In between of running my application activity manager just display message I/ActivityManager(159): Starting: Intent { act=android.intent.action.MAIN cat=[android.intent.category.LAUNCHER] flg=0x10100000 cmp=com.rfb.client/.RFB_ClientActivity bnds=[182,205][238,271] } from pid 159 it keeps on displaying this message.

Any idea why this info is shown in log ? what is the meaning of this message ? Please let know if you know about this.

Any idea why this info is shown in log ?

Because the Android engineer responsible for ActivityManager chose to log it. Frankly, I wish this engineer had not done this.

what is the meaning of this message ?

It means Android is starting an activity, using the Intent described in the log message.
