Sometimes when I'm working with my android projects, and hook up my phone, the logcat in Eclipse starts to report EVERYTHING that's happening on my phone, not just the stuff relative to the project I'm working on. It only does this sometimes though.
How do I stop it from showing everything and just show the things relative to my project?
EDIT:
I forgot to say i already know about filters, sorry. I was just wondering why sometimes eclipses logcat shows everything my phone is doing, while other times it only shows what's relative to the project i'm currently working with when running it on the phone.

Then it is because you have a filter selected and/or eclipse has encountered an error and is just not showing everything it should be.
First Answer
Next to your logcat window should be a Filter window. Create a filter there. Then select the filter by clicking the filter you have made or was put there automatically by eclipse.
You can filter on several things.
Most people will create a static string in their Main Activity/Service containing the application name. Use this static string as your TAG for all of your Logs. Then you can filter on this string you put for the static string.
Also, right clicking in the logcat window will bring up a filter dialog.
You can click on the session filter (left)
Use
Log.d("key","value");
Log.d("key1","value");
Log.d("key2","value");
Log.d("key2","value");
If you want to see only key1 messages ,then go to Logcat
click on add new logcat filter at top left corner(green color + symbol)
then a dialog box will be shown
then a dialog box will be shown, in that write Filter Name ie anyname
and in , by Log Tag write key1 and click on ok button.Now you will see a new filter on left side of your logcat
click on that,you will get only key1 messages
I could fix this by selecting my app in the DDMS-view.
It is important to select the app and not only the device. Latter will only create this useless "(Session-Filter)"
And this happens "sometimes" quite like the author asked for, i think if you change your mobile phone or just disconnect it.

You can also setup your own custom filter to specify more details such as filtering messages with the log tags or with the process id that generated the log message. The add filter, edit filter, and delete filter buttons let you manage your custom filters.
Use filters to define what you want to look at.
If you are using Eclipse, when viewing the LogCat view, there is a little green "+" button in the upper right corner. This will allow you to create a filter. Simply give your filter a name and input the TAG it should filter by.
If you are developing with Eclipse creating a log filter is what you are looking for.
If you are using logcat through adb from the command line: Filter LogCat to get only the messages from My Application in Android?

In the old logcat all I would have to do is type my package name in the search bar.
e.g com.dave.mynewapp
but now when you type in the package name it constantly displays log messages EVERY SINGLE SECOND that I don't need making it hard to debug.
Also now, the cursor doesn't automatically scroll down when a new log appears making it even more frustrating
I am able to filter it by typing the activity name... e.g MainActivity, but it becomes very annoying to type out every single class name that I have logs in.
Is there a way to get all the logs I manually created, but ignore the clutter I have in the picture above?
maybe you can try this :
filter specify the package name package:com.dave.mynewapp
filter specify the Tag tag:MainActivity
filter mutil tags like package:com.dave.mynewapp tag:MainActivity tag:MainActivity2
detail info about this link https://developer.android.com/studio/debug/logcat
I had luck by filtering on: tag:info
var tag = "info"
Log.i(tag, "Names: $names")
I am not able to see the logcat app crash and start the last activity so how can i see the logcat where the error came. please help me.
You should see buttons called 'TODO', 'LOGCAT', 'BUILD' and 'TERMINAL' at the bottom of your Android Studio Window. Click Logcat, run your app and you'll see the error whenever your app crashes.
Click logcat on the down layer of the screen
Or press Alt+6.
Then:
select the correct emulator name from the first dropdown menu.
select correct package name from the second dropdown menu.
select "error" from the third drop down menu.
select "show only selected application" from the last drop down menu.
try it :
got to logcat the down layer of the screen
check all of things on below :
1-check ur emuleter name equal ur device if running
for exmaple i have device Nexus_5x_API_25
when i run this device show to me this name in field
2-beside this menu check ur package correct with this project package
for exmaple in my have elhaji.contact its my packagename
3-set tic on Regex
4- set verbose in menu
5 check u dont write on fieldtext its must be empty
6- set no filter in menu
u can also this picture
sry i cant bad speak english im learning :))
After many tries i got the answer. Only exception handling can hold the logcat screen or won't let the start new activity. So you can trace the errors
I want to show all the log cat that I wrote in my code
I have several activities , and every one has a different tag.
In the logcat I just want to show these logs I wrote in my code in these specific activities .
Any idea?
Check "Regex" checkbox in logcat window and than use "tag1|tag2" as a filter.
You can create Log Cat Filters for each activity
Android Monitor -> Edit Filter Configuration (select from right top dropdown)
enter your tag in Log Tag and press Ok
Then you can select any filter to debug as needed.
I'm wondering why a shortcut combo Alt+Shift+A, S does not work (S at the end is needed because of a conflict with another shortcuts). After Alt+Shift+A the options dialog appears, but after clicking S nothing happens. It's annoying to use the mouse for such an operation so I would love to have a solution. The other questions I've looked for didn't help.
Thanks!
You have to have the string highlighted first. Once it is highlighted, performing the shortcut Alt+Shift+A;S should bring up the prompt for extracting an Android String. You can also use Ctrl+1, and then choose the option from that menu.
Clicked on create filter could not figure out from docs how to create a filter for say two or more tags. If I have two tags com.test.TestClassA and com.test.TestClassB how do I create a filter that shows log for both of these classes? I saw how you can start ADB for only certain tags, but how can this be done in eclipse? Please provide details thanks. What exactly do I need to enter on the tag line when creating a new filter in eclipse?
As pointed by Brain Reinhold you can combine tag filters with vertical bar | (which obviously means logical "OR"). You can also use that (as well as other Regex) syntax in the logcat search box (by preceding tags with tag: prefix):
tag:com.test.TestClassA|com.test.TestClassB
More complex filtering is also possible. For example here is the search filter that displays messages from either android.process.media or com.android.camera apps, which have at least one digit (\d) in the message text and are tagged with either dalvikvm or AndroidRuntime tags:
app:android.process.media|com.android.camera tag:dalvikvm|AndroidRuntime text:\d
One short and useful filter is tag:^(?!dalvikvm) which removes all those noisy Dalvik logs.
It's also worth mentioning that you can quickly disable any part of the filter by placing vertical bar at the end of the part you wish to disable (e.g. placing | right after app:android.process.media|com.android.camera in the example above effectively disables filtering by application name while still preserving filtering by tags and text).
In the latest version of the SDK for Eclipse which now shows two versions for logcat (one deprecated); in the undeprecated version one can combine filters using OR bars: |.
For example when clicking on the + and bringing up a dialog to create a new filter, give your filter a name and then in one of the fields (for example TAG) enter com.lampreynetworks|Bluetooth and you will see output for all tags containing com.lampreynetworks and Bluetooth. The '*' is implicit here as if any part of the TAG contains any of that text it will be displayed. Also note, there must be no spaces between the OR bars!
I have not tried combining the 'by TAG' and 'by (some other option)' but somehow I have a feeling that will not work.

The "Log tag" field accepts Java regular expressions, so do this:
^com.test.TestClassA$|^com.test.TestClassB$
which matches exactly those tags you specified. You could be more economical/efficient/whatever with the regular expression, depending on how much you want to muck around with that.
It is not possible right now.

I also wish it were...
I just do it from the command line. Having a different terminal for each adb filter. Then if you line them up side by side you can get a good idea of what is happening.
The only way I have seen is Create a Filter using PID so that evey log message of your application will be displayed in that Filter. I wonder if this is possible through tag names in the current version of the ADT for eclipse.
Use proclogcat: http://devtcg.blogspot.com/2010/04/logcat-improved.html
It lets you filter by your package name instead.
