![]() When we use different queries, the query history window will contain too many queries. The "Query history" feature allows to delete items by pressing "X" only in Android Studio Electric Eel (2022.1) or higher, but in Android Studio Dolphin you can use keyboard shortcut for it.Įvery query filter also shows the number of found log entries. Now, we can delete queries from the history, mark queries as a favorite or set a specific name for a query. The latest version of the logcat has a few improvements to the "Query history". The is:stacktrace returns log entries that represent anything that looks like Java stack trace.The is:crash returns log entries that represent the crash.You can find all crashes and stack traces using the is key. age:2d returns logs for the last 2 days.age:2m returns logs for the last 2 minutes.age:30s returns logs for the last 30 seconds.We can filter logs by timestamp range by using the age: parameter. If you want to use a regular expression in logs, you can use the "~" after the key ( tag~:).Įxample: Display logs which have a tag with the “Nav” postfix. Query: package:mine tag:HomeScreen -tag:HomeScreenSettings To exclude log entries, you can use the "-" sign before key ( -tag:).Įxample: Show logs for all tags, which start with "HomeScreen" prefix and exclude logs for "HomeScreenSettings" tag. Query: package:mine tag:HomeScreen test log Query: level:INFO displays logs for INFO, ASSERT, DEBUG, WARN, and ERROR level valuesĮxamples of using the specific values for filtering out the log entries.Įxample: Show logs with WARN and ERROR levels.Įxample: Display logs which have the "HomeScreen" tag, and the message starts with "test log" text.Query: level:DEBUG displays logs for DEBUG, WARN and ERROR level values.When you filter by level, remember that level value in logcat will be greater than or equal to the query level value. Let’s take a look at specific keys that can be used for filtering out log entries: In the new version, logcat combines the search and filter into the query input field and displays it on the main screen. The main problem with this approach is that the filter parameters were always hidden from the developer. ![]() In the previous version of logcat, we had “search” on the main screen, but filters were located on a separate menu. Such memos include message, process ID and package name. The new logcat displays additional messages when the application starts or stops (closes or crashes). ![]() Additional logs when app starts and stops Let’s check the most interesting features in a new release. Plus, you can have multiple logcat windows inside the Android Studio. This version of logcat includes not only a redesign but also improvements and new features which simplify reading logs and help to find required information faster. Note: You cannot pause and resume a new logcat in the Android Studio Dolphin, but this feature is available in the Android Studio Electric Eel.

The Android Studio Electric Eel (2022.1) includes a new logcat activated by default. It is available from the Android Studio Dolphin (2021.3) as an experimental feature. Recently, the new version of logcat was introduced. It’s a helpful tool for debugging because it provides detailed information about the state of the application and device at a given time. ![]() It helps to identify and fix bugs in the code or improve the performance of the app.Īndroid logcat allows us to view logs on an Android device or emulator. Debugging is an essential part of the software development process.
