Android - Saving logcat to a file and limit the file size

Question

I am able to save the logcat to external file with the link - Saving Logcat to a text file in Android Device

Is there any way to limit the file size? i.e. For e.g. I want the output file size shouldn't exceed 2MB. If it exceeds the limit, it should clear the existing file content and start writing the new content.

Thanks in advance.

you need to set the condition while reading the file – rachna Nov 08 '19 at 12:28 — rachna, Nov 08 '19 at 12:28

You can try this:

File file = new File("text.txt");
long filesize = file.length();
long filesizeInKB = filesize / 1024;
long filesizeinMB=filesizeInKB/1024;

I think part of your answer is missing, please also format only code as such – Giulio Caccin Nov 09 '19 at 09:31

Instead of executing

 process = Runtime.getRuntime().exec("logcat -f " + logFile);

Add

 process = Runtime.getRuntime().exec("logcat -f " + logFile + " -r <kbytes> -n <count>");

Example for a maximum of 10 files, where each max size is 500kb :

 process = Runtime.getRuntime().exec("logcat -f " + logFile + " -r 500 -n 10");

You can also defined theses variables (500 and 10) in your environment variables to keep your code maintainable.
