Shutting off my own app's LogCat output before releasing an app to the market is straightforward. I also know how to selectively filter LogCat message by tag and/or id for my own debug convenience.
But now I am interested in something that may be much more difficult (perhaps impossible?): Disable all LogCat output, including & especially those coming from 3rd-party services like TtsService, GoogleLoginService, etc.
Is this possible?
To further clarify: I am not interested in filtering out messages for myself. I am rather interested in disabling 3rd-party messages for whoever downloads my app from the Android Market. Is this possible?

You can use ProGuard to remove completely any lines where a return value is not used, by telling ProGuard to assume that there will be no problems.
The following proguard.cfg chunk instructs to remove Log.d, Log.v and Log.i calls.
The end result is that these log lines are not in your release apk, and therefore any user with logcat won't see d/v/i logs.
