Filter LogCat to get only the messages from My Application in Android?
Package names are guaranteed to be unique so you can use the Log
function with the tag as your package name and then filter by package name:
NOTE: As of Build Tools 21.0.3 this will no longer work as TAGS are restricted to 23 characters or less.
Log.<log level>("<your package name>", "message");
adb -d logcat <your package name>:<log level> *:S
-d
denotes an actual device and -e
denotes an emulator. If there's more than 1 emulator running you can use -s emulator-<emulator number>
(eg, -s emulator-5558
)
Example: adb -d logcat com.example.example:I *:S
Or if you are using System.out.print
to send messages to the log you can use adb -d logcat System.out:I *:S
to show only calls to System.out.
You can find all the log levels and more info here: https://developer.android.com/studio/command-line/logcat.html
http://developer.android.com/reference/android/util/Log.html
EDIT: Looks like I jumped the gun a little and just realized you were asking about logcat in Eclipse. What I posted above is for using logcat through adb from the command line. I'm not sure if the same filters transfer over into Eclipse.
How to filter Android logcat by application?
Edit: The original is below. When one Android Studio didn't exist. But if you want to filter on your entire application I would use pidcat for terminal viewing or Android Studio. Using pidcat instead of logcat then the tags don't need to be the application. You can just call it with pidcat com.your.application
You should use your own tag, look at: http://developer.android.com/reference/android/util/Log.html
Like.
Log.d("AlexeysActivity","what you want to log");
And then when you want to read the log use>
adb logcat -s AlexeysActivity
That filters out everything that doesn't use the same tag.
How to filter logcat in Android Studio?
There are two ways to do this, both are in the Android tab at the bottom of the IDE (where the logcat output is displayed).
First, you can simply type something into the search box at the top and it should filter only messages containing the text you type.
Second, you can do advanced filtering by clicking on the dropdown at the top right, which should be displaying No Filters by default, and choose Edit Filter Configuration
and specifying what to filter on. Using this method you also save the filters and can re-use them by selecting them in the dropdown.

Filter android monitor logs by package name
You can certainly view logcat with the help of adb
.
Use command like
adb logcat | grep <your_package_name>
as per @TruongHieu mentioned in comment, flag is true
.
for more info.
adb logcat filter by package name
You can filter adb logcat
output by process ID by using the --pid=<pid>
option.
To get the process ID for your app, you can run adb shell ps | FINDSTR <app name>
(for Windows) or adb shell ps | grep <app name>
(for *nix and OSX) while the app is still running.
Since you are trying to get logcat output after the app has crashed, the ps
command won't work. You can generally filter logcat output by running adb logcat | FINDSTR <search term>
(for Windows) or adb logcat | grep <search term>
(for *nix and OSX).
This way, you can still assign meaningful tags to your debug messages and further filter on them.
Hope this helps!
Setting custom filter in Logcat
I was able to solve this by switching the Log Level to verbose and removing the space from the TAG.
private static final String TAG = "LOG";
public void LOG_ENTRY(String what) {
Log.d(TAG, what);
}
