I am working in an Android Project. I want to see Logs in Window terminal rather than in Android's Logcat.Any suggestion?. I put Logger in my project for example:
Log.d("ufo","Plane inventory Listener is called");
I also want to see Logs of "ufo" in window's terminal?
You need to read logcat documentation for details.
You can see log messages into terminal using below command
To see all logs
adb logcat
Filter logs (like you want to see logs for ufo)
adb logcat | grep "ufo"

In my android app, I read my Log messages. After reading the log message I want to clear it. So I tried following code for clearing the app's log .
ProcessBuilder().command("logcat", "-c").redirectErrorStream(true).start()
Runtime.getRuntime().exec(arrayOf("logcat", "-c"))
Runtime.getRuntime().exec("logcat -c")
Runtime.getRuntime().exec("logcat -b all -c")
But above code is not cleared the log message. But whenever I used adb logcat -c from PC's command prompt it works properly. So how to clear the logs pro grammatically in android.
There is no way u can write a code to clear the logcat in Android Studio but there is a way u can clear logcat every time u run an app.
Follow these steps:
1. RUN
2.Edit Configuration
3. Then when the "Run/Debug Configurations" dialog shows up, click the Logcat tab (now called Miscellaneous in Android Studio 2.x)(idk about if u are in the latest version)
4. U will see a "Clear log before launch" checkbox, now click on it check it.
5. Ur logcat output will be cleared before each new run in Android Studio.
Hope this helped u.
I am using an open Source Library for my Android Application. However its developers did not remove all the Log statements before releasing it. This causes a lot of ruckus in LogCat.
Is there a way to turn the Log Messages from a specific Java library Off ?
You can Filter LogCat outputs by some specific Tag names , like (adb shell)
adb logcat -s "TAGNAME"
Android Studio's logcat is unusable; it goes in and out and rarely shows messages on restart, so I've started using adb logcat on my terminal. Reading http://developer.android.com/tools/debugging/debugging-log.html gives examples of filtering with a tag. What if I don't know the tag, but want to show all error with an error substring I know?
You can always simply pipe the logcat to grep:
$ adb logcat | grep 'known error substring'
If you are on Windows, then use find instead:
C:\> adb logcat | find 'known error substring'
You can try pidcat (by Jake Wharton).
It's a "colored logcat script which only shows log entries for a specific application package", as the author says.
If you're on windows, you can clic on left upper corner > Edit > Search and then introduce the substring you know.
Most probably the terminal for Linux has the same feature, but I don't know how to access to it.
I am testing an app with 2 devices communicating using sockets and monitoring the timestamp values. I select the required device name from the DDMS perspective. But some initial logs are missing(as I have many Log.d statements in the code). I want to store the whole log file after I stop apps in both the phones. Can someone tell me how this can be done in command line using adb? I couldn't find any example for 2 devices.
Thanks
You can try with two console and get logcat separately for two devices
Get serial no for each devices using adb devices
and save logcat as text files
console 1: adb -s <device1serialNO> logcat -d > logcat1.txt
console 2: adb -s <device2serialNO> logcat -d > logcat2.txt
You can filter result for your given tag if needed
Before launching your application you can start the following command in your terminal:
adb logcat <your_application_log_tag>:V *:S > file.txt
<your_application_log_tag> is a log tag that you use in your application. *:S means that you suppress all log outputs from other components. > file.txt redirects the output of the command to file.txt.
The cause of the problem is that for logging Android has a buffer in RAM and if it becomes full it rewrites the most old entries (FIFO). The command I've provided will store the log on your computer.
I want to use ECLIM plugin for VIM during android development.
The main problem : I can't run my project from eclim, so I can't see logs and errors.
I know such command :
:Ant debug install
This command compiles and updates my project to connected device. I have to run it manually.
I'm not lazy, and is not problem to run it.
But I wish to see runtime's Logs.:)
open a terminal,and input adb logcat，then you can see the log.
have a try :)
If you want to see it exclusively within vim then :!adb logcat will display the logs.
Use this in vim:
:!ant debug install && adb shell am start -n your.package.name/.YourActivityName
That will fire up the app in your device. For logging I just want to complement that if you log in your app use a tag and filter the log by a tag like so: adb logcat -s "tagname"
