Android logging to a file, any recommendation?

I have been trying to investigate a common issue that is happening in my turn-based app in prod. From some reason, at some point, the turns are messed up I have not been able to figure out the reason for that. So I decided to create a log file and send this log file when this issue happen.

I don't want to use log cat as it requires permission. I need to use my own logging file so user is assured that its only my logging statement. What do you recommend I do? Just open a file and append to it my logging statements, or is there a library that I can use that would work with android for logging to a file? Thank you

I created the RemoteLogger library for same situation (need to troubleshoot production only issue in my app).

Provides hooks to append, start, stop, send, and delete log file.

Logcat doesn't require any permission. If you want create your own log, just append log into a text file.
I tried this way myself (require write file permission):

public static void appendLog(String text)
{
    File logFile = new File("sdcard/log.file");
    if (!logFile.exists())
    {
        try
        {
            logFile.createNewFile();
        } catch (IOException e)
        {
            e.printStackTrace();
        }
    }
    try
    {
        // BufferedWriter for performance, true to set append to file flag
        BufferedWriter buf = new BufferedWriter(new FileWriter(logFile, true));
        buf.append(text);
        buf.newLine();
        buf.close();
    } catch (IOException e)
    {
        e.printStackTrace();
    }
}

Another choice is log4j for android, and it also require WRITE_EXTERNAL_STORAGE permission
