Logcat adb logcat <Log Tag>:<Log Level> ... *:S

e.g. - adb logcat ClockOut:V AndroidRuntime:E *:S

AndroidRuntine:E will show the stacktrace when an app crashes

Log Levels: V - Verbose (lowest priority D - Debug I - Info (default priority) W - Warning E - Error F - Fatal S - Silent (highest priority, nothing is ever printed)

The *:S is necessary to filter out all unwanted messages.
