aLogcat – Android Logcat Application

aLogcat market barcode

There are several “log view” applications on the market. All of them provide a means to send your log file contents, typically via email. This is one good approach, but it doesn’t handle the use case where you don’t have immediate access to a PC email client to view the results. aLogcat is an Android application that allows you to view your Android device log from the device itself. It provides a scrolling, color-coded log that is filterable by keyword and log level. It also supports output in various log formats. aLogcat also covers the send log use case by allowing a snapshot of the log to be sent off to another device.

This is mainly an app for developers, but it is also useful for power users that are willing to get involved with developers to help them find problems in their applications. Most Android developers are small scale hobbyists and can’t devote full-time effort and money to rigorous testing across multiple devices. I hope this app lowers the barrier for involvement of the average user in the development cycle.

    Right, it doesn’t crash or so, just uses 100% cpu seemingly forever and is unusable. Says “Reading log data”, but gui never wakes up again.

    I new to Android and am having problems downloading the alogcat through the Market on an HTC Hero phone.
    Any suggestions would be appreciated.

    The download seems to hang. I’ve stopped and restarted but it’s taking longer than an hour each time.

    • Jeffrey Blattman says:

      sorry, i don’t have any good suggestions. there are a lot of reasons why your download might not be going through … poor network connection, out of memory of your phone … aLogcat is hosted no differently that any other app, so i can assure you it’s not specific. i would suggest you perhaps visit forums for your phone and see what you can find.

    Is it safe to send the log file to a developer? Couldn’t there be personal info in there?

    • Jeffrey Blattman says:

      there is nothing to prevent a developer of an arbitrary app from writing personal info to the log. that being said, as a rule developers should and do not do that. i have never seen personal info written by any application.

    Does anybody know which type of video recordsdata are supported? I bear in mind the Instinct only may dl 3gp utilizing opera mini. I downloaded the twist ap, possibly that is the issue? How can I watch movies from sites other than youtube? Which file varieties? Often I’m given the choice of 3gp or mpeg4. Cannot get either to work. Thank you for your time! Rattling I wish I used to be eligible for the upgrade to EVO!

    MIME-type of the SEND Intent is incorrect. It is “plain/text” instead of “text/plain”.
    At least my application ( crashes.
    The intent is sent by Send menu command.
