About Log File Viewer
A simple - but powerful - viewer for .log files.
* Optimized for performance - handles large files very well.
* Built-in search function
* Custom colored highlighting of INFO, WARN and ERROR log messages (Pro)
* Ad free
A common use case for Log File Viewer is that someone sends you an email with an attachment having the .log file ending. Log File Viewer lets you display the contents of this file with a single tap of your finger. No separate downloading is required. This is particularly useful for users who used to receive the message "There is no installed app that can open this attachment." when trying to open .log files.
* Optimized for performance *
Log File Viewer only actually renders the lines that are visible on your screen. This enables it to keep memory usage to a minimum and handle large files with great speed.
* Built-in search function *
The built-in search function lets you find any text in your log file. The found string is highlighted in green. This is very useful when looking for specific information in your log files.
* Custom highlighting *
Log files very often have different kinds of messages - infos, warnings, errors, etc. It's extremely helpful when reading log files to be able to visually distinguish these different log levels. Log File Viewer lets you configure the strings which identify INFO, WARNING and ERROR messages and then highlights lines containing these strings in yellow, orange and red, respectively (Pro only).
* Permissions *
The only permission Log File Viewer requires is read access to your phone or tablet's external storage. The *only* reason for this is to be able to display log files which are stored there. Log File Viewer never reads any data other than the log files it displays to you.
* Log File Viewer Pro *
Most functionality of this app is available in the free version. Some features require purchasing a Pro version from within the app:
+ Repeated searches
+ Custom color highlighting
+ Changing the font size
The money thus earned will be used to sustain the further development of this project.

Works for viewing .log files. Wish it did not automatically start at the end of the file but rather it be an option. Also would be great if there was a search option built in so that you could easily within the log file rather than having to scroll up and down till you find what you are looking for. Thanks for your work.

Does what it says. However it is difficult to scroll to any particular place in a long file (you'll spend all day swiping down to try to get to the top)

Doesn't work with my Android S5 lollipop. When I attempt to open a file with a .log extension, the phone states "no apps can perform this action". Geez, you can use any text editor on a, PC (computer ) to open log files! Can the developer respond to this? Thanks

3 stars because it's the only app I can find that will let me open .log files. However, it lacks the ability to copy text from the file (really?..) and there is no way to turn off word wrap. If these features were both added then this would be a 5 star app and worth the upgrade to pro.

There is no icon, the only way to launch it is by opening a .log file from email or some other source. Some descriptive note somewhere would be good too indicate thus, or even let it launch as a regular app that says "open a log file to use this app", like some widget-only apps use. It works on my Galaxy S5 with 5.1.1 using the AirWatch Inbox app. I did close (from manage applications) the app before it would work, I guess that forces Android to refresh file association handlers?

This app is very fast and font scaling options in the paid edition present well. You need to touch the screen for a second to bring up settings and search which is not obvious. Other than that its very good!

What a usability disaster. No icon, directions etc. More of a dev tool I guess? But it has ads? Wow what an instant "uninstall"

I've been looking for an app to open log files from my email. This one does it. Would like to turn off wrap though. Might buy for the other features. Finally I'm able to read my log files on my phone without having to switch to another app and search for the downloaded file. I can never remember what folder they're in. Thank you. Big help. I just remembered, I'd like this to work on .err files, and for that matter, any extention.
