Logcat is the command to view and filter information from the Android logging system, but more often the name is used as a synonym for the Android logging system itself.

Logcat is the command to view and filter information from the Android logging system, but more often the name is used as a synonym for the Android logging system itself.

Logging information from Logcat is vital for diagnosing problems and debugging Android apps.

To retrieve information from logcat manually the Android Debug Bridge (ADB) command line tool is used. Alternatively the Eclipse IDE provides a logcat view in its Android DDMS perspective, that automatically retrieves logging information

Detailed information on the logcat command is available at the Android Developers API.

For non-developer questions, see the Android Enthusiasts StackExchange.
