Filter the message log
You can filter the message log so that it only displays the messages that match the filter. You can filter by:
Filter by text
To filter the message log by text, use Filter Input and Filter Options in the toolbar. The Android Logcat window checks the text in Filter Input against the text in each message and only displays messages that contain the filter text. Filter Options determine whether the filter text is case-sensitive and also whether to treat the filter as a regular expression.
Filter by priority
To filter the message log by priority, right-click the Priority column header in the message log and select the priorities you want to appear in the message log. For information about the types of priority, see Filtering log output.
Filter by tag
Tags indicate the origin of the log message. To filter messages by tag, right-click the Tag column header in the message log and select the tags you want to appear in the message log. If you aren't currently filtering messages by tag, you can also right-click a message and select Add Tag to filter by that message's tag.
Tag Control
The Tag Control window is an interface that helps you to set which tags to filter messages by. To open it, right-click the Tag column header in the message log and select Tag Control. In the window, you can manage a list of tags and enable/disable them to change which tags to filter messages by.
Filter by process ID
To filter the message log by process ID, right-click on a message and select Filter by process id. When you filter by process ID, the result is similar to selecting a specific application to view messages from.
