Android desktop log viewer [closed]

Asked 1/12, 2010 at 13:58 Answered 22/3, 2017 at 5:54

My Android application may save logcat logs to a file. This log file is then sent to developers for analysis.

Is there a nice desktop android log viewer application, which would visualize these logs?

I wasn't able to find a ready to use tool in Android SDK. Maybe I missed something there?

Personally, I read logs with less and it's search feature, or occasionally emacs, but that's probably a less polished solution than desired – Buttons 1/12, 2010 at 15:10

Desktop tool for reading android logcat log file, the same as DDMS. enter image description here The purpose of this tool is to allow developers to quickly locate, analyze, problem-solving, rather than struggling in the log file.

I can't get this tool to read my logs I created with adb (neither "adb logcat -v long > somefile.log" nor "adb logcat > somefile.log"). When I choose a log file, nothing happens. How do you create the logs? – Simonize 21/1, 2014 at 15:14

Got it, has to be "adb logcat -v time" – Simonize 22/1, 2014 at 12:54

Didn't get it to run on OS X (Maverick) or Windows 8.1. Nice pic though. :/ – Bedad 11/4, 2014 at 14:20

In the discussion board, there are instructions on how to make this run on 64-bit Windows. Didn't start doing that, but just so you realize a) it needs to be done b) it's possible. – Bedad 16/4, 2014 at 14:17

Even though it's java, it unfortunately won't run on my linux (Kubuntu 14.04, 32 Bit). It terminates with an exeption when trying to start. – Etna 19/7, 2014 at 1:37

Can somebody tell me where is the location of logcat file in my device? – Irisirisa 30/3, 2018 at 6:14

How can I use this in windows? I can't find the link in the group section. – Craniology 9/7, 2018 at 12:59

I've tried logview-0.19 - works fine for my 13Mb logs.

Make sure to mark ./logview and ./lib/logview.jar as executable when running in Linux.

Seems to do the job. I'm surprised by how few tools exist for this job. I feel an itch... :) – Zanezaneski 30/7, 2012 at 20:51

Another offline tool – Chastitychasuble 2/2, 2016 at 10:48

This is my favourite ♥ – Galumph 6/10, 2016 at 15:18

@HenriquedeSousa what do you mean by "offline"? It is possible to capture live logs from the connected device with logview, you just need to set up adb location if the latter isn't on the PATH. – Hecht 26/2, 2020 at 21:11

I found Online LogCat Beautifier to which can colourize given LogCat for easy reading. Really nice tool and it uses JavaScript, which means nothing is stored anywhere!

Update:

The link is no longer accessible, and luckily enough for us, Android Studio now supports pasting the LogCat into its "LogCat" tab (previously "Monitor"). Upon pasting, you'd have the options to search/click like a normal LogCat's log.

This is a tool to analyze offline logcat records. – Chastitychasuble 2/2, 2016 at 10:51

You should also check out Android Studio's "Analyze stacktrace" by going to Analyze > Analyze stacktrace. See this G+ post plus.google.com/+IanLake/posts/jk4x5RoyXJm – Parley 2/2, 2016 at 11:33

@HenriquedeSousa in case last comment didn't generate a notification. – Parley 9/7, 2016 at 9:12

Splinter Log works on MacOS and can do a few things better than DDMS, like grouping tags, resolving pids to package name, etc. https://splinter-log.com

Looks promising, but Mac-only =( – Balsa 10/4, 2017 at 20:6

How to use this for seeing log information of connected device ?? – Hyperploid 18/1, 2019 at 12:10

This answer is not clear on how to actually use the software to solve the problem presented in this question... – Dang 17/12, 2019 at 3:7

I use coloredlogcat for viewing logcat logs on the console. You should be able to do the same.

cat logfile | coloredlogcat.py

It should work out of the box. If it doesn't, I'm sure only minor modifications are needed. Have a look at this link coloredlogcat for details.

You can use Android Debug Monitor or DDMS without Eclipse.

Merissa answered 14/10, 2013 at 5:32 Comment(3)

Just an update.. DDMS is now deprecated. Instead we should use: sdk_path/tools/monitor. On OSX, ddmscan't save some custom filters I created, whereas monitor can. – Throughcomposed 2/6, 2014 at 17:24

Yes, that is Android Debug Monitor, but there wasn't any online details about it when I wrote my answer, and it is very similar to DDMS. – Merissa 2/6, 2014 at 21:48

Nothing happened running sdk_path/tools/monitor on windows. – Mats 19/2, 2021 at 7:42

I've tweaked log4j Chainsaw V2 and the (VFS)LogFilePatternReceiver to allow Chainsaw to read events from Android log files generated via logcat -v time

Download the latest developer snapshot of Chainsaw (Mac DMG and tarball available): http://people.apache.org/~sdeboy

Save this XML off as a file (after tweaking the fileURL):

<?xml version="1.0" encoding="UTF-8"?>
<log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/" debug="true">
<plugin class="org.apache.log4j.chainsaw.vfs.VFSLogFilePatternReceiver" name="android-log">
    <param name="appendNonMatches" value="true"/>
    <param name="autoReconnect" value="true"/>
    <param name="fileURL" value="file:/path/to/android/log"/>
    <param name="name" value="android-log"/>
    <param name="logFormat" value="TIMESTAMP LEVEL/LOGGER(PROP(PID)):MESSAGE"/> 
    <param name="customLevelDefinitions" value="V=TRACE,D=DEBUG,I=INFO,W=WARN,E=ERROR,F=FATAL,S=OFF"/>
    <param name="promptForUserInfo" value="false"/>
    <param name="tailing" value="true"/>
    <param name="timestampFormat" value="yyyyMMdd HH:mm:ss.SSS"/>
    <param name="waitMillis" value="2000"/>
</plugin>
</log4j:configuration>

And then after starting Chainsaw, select the 'Use a Chainsaw config file' option from the 'File, load Chainsaw configuration' menu, browse to this XML file, select 'always start Chainsaw with this configuration' and press OK.

This works well on os x, solving my problem that the Eclipse logcat view often stops working. Exactly what I was looking for! I see the latest stable build is dated after your post so I'm wondering if it's now good to use rather than the snapshot you suggest? – Siamese 3/4, 2013 at 4:40

I like LogExpert. It has great filtering options and it is pretty fast. So I have created a custom columnizer that parses LogCat logs. It has some improvements to be able to parse my custom logs with method and line. You can download it here.

Looks again like Windows only :-( – Etna 19/7, 2014 at 0:56

The link is broken. This link should be working: github.com/zarunbal/LogExpert – Outtalk 23/1, 2022 at 18:28

Personally I like TailExpert which I use together with logcatUDP to capture logs from multiple android targets, logcatUDP sends the log over the network to tailexpert where I capture it and view the side by side. But you can also read the logs from file if you like, it's a tail program so it will add logmessages to the view when they arrive. You can filter messages on keywords and use colors to identify certain logmessages. The other thing I like is that in tailexpert you can create columnizers on the fly and easily hide one or more columns or change the column order. The program is packed with features and I recently just started to discover the use of notifications to place bookmarks on the fly and halt the log when a certain logmessages passes by, which makes navigation so much quicker. Just check it out, you can download it here.

I went with http://mlogcat.tistory.com/ now, since Logcat Offline Viewer quit its job probably due to JAVA update.
