If you've been around for a long time on Android, you've definitely heard of it sometime Logcat, or Android log. Although it is a developer-focused resource, it is also useful for advanced users who are trying to fix or troubleshoot a mobile or specific application.
Here we will tell you what this Logcat really is, as well three different ways to consult event log, whether you have root access to your Android phone or not.
What is Android Logcat
Logcat is the name of the tool to access the Android system message. App developers can use this log to print useful messages to check for possible problems and problems with the app. Logcat is an ADB command.
For this record, applications may include messages between uses, when a record is first created, a custom identifier and the message in question are included. There are six types of messages, depending on their level of importance, and that on Logcat is usually abbreviated:
- V / Verbose: very low, with more information than necessary
- D / Debugging: useful debugging software messages
- I / Info: contact information
- W / Warning: messages with warnings
- Error: application errors
- F / Death: major errors
In summary, Logcat for Android is something like an Android logbook for Android, where apps sign up in the background with virtual reality everything that happens is mobile, from poorly related internal messages to user-defined errors.
How to see Logcat for Android
If you're interested in seeing Android Logcat, there are several ways to find it. In both cases you will not need root, although you will need special permissions, ADB or the help of the standard Android IDE, Android Studio.
Using apps is one of the easiest ways to communicate with Android Logcat, especially since it usually we will show it clean. The best app to accomplish this is Logcat Viewer, which you can use with root or by giving special permissions with the help of ADB.
You should remember that Logcat reading apps do not work on all mobile phones, because sometimes a mobile phone will not give permission to read the record even if you follow the instructions strictly. Of course, the site works, the app shows you it well too with filters and searches.
As we said before, Logcat is the ADB command, and consequently the most common way to communicate in a book on mobile connectivity using ADB, is usually with the help of a cable (though Android 11 adds wireless connectivity).
Otherwise, the process is as easy as writing a command.
adb logcat. This will show in real time the Android logcat in command line from your PC. If you want to sort or search, you can check out the full syntax here. For example, to see only error messages, use the command
adb logcat *:E.
With Android Studio
Being a developer tool, Android Studio is clearly designed to showcase the Android logcat. From the Logcat tab You can view the log in real time, with the benefit of having the same access filters and settings available through ADB, but available with buttons and menus.
From here you can see the Android subscriptions connected to the mobile phone (and with USB debugging activated and given permission for ADB connection), filters by priority, filter the filters and the possibility to restart and stop clicking.
