This lightweight library lets you save logs to a file. This can be very helpful when debugging issues that may not occur when your device is connected to LogCat.

dependencies {
    implementation 'com.github.akm0012:LogToFile:1.0.2'
}

// A simple log
FileLogger.log("This is my first Log!")

// Log a throwable
FileLogger.log("Something broke!", throwable)

The easiest way to view the logs is to use this helper method that will create a Send Intent.

startActivity(FileLogger.getIntentToSendLogs())

// Delete all the logs 
FileLogger.deleteAllLogs()

// Delete a specific log file
FileLogger.deleteLogFile("MyCustomLogFileName.myApp")

If you'd like to change the file extension you can. However, the file will still be a plain ole text file. So be sure to open the file with your favorite text editor.

FileLogger.setFileExtension(".myApp")

This will set the name of the file that will be saved.

FileLogger.setLogFileName("MyCustomLogFileName")

1. Use this library with Jake Wharton's Timer. Planting a File Logging Tree is an easy way to turn on/off file logging from one spot.
2. Don't forget this will create a text file that could potentially grow unchecked. Don't forget to delete the log files every now and then or implement a way where you only keep the last X days worth of logs.
3. Avoid using this in production. No one likes their app slowing taking up more and more space. (See point #2)
