I want to carry the most recent 1000 full logcat logs when Android crashes

Problem Statement

I found that when native crashes, the EventProcessor process will not be triggered, so the logcat I captured is the log of the next startup. The code is as follows. How can I capture the log when the crash occurs and save it, and then report it with the next startup.

options.addEventProcessor(new EventProcessor() {
                @Override
                public SentryEvent process(SentryEvent event, Hint hint) {
                    try {
                        String logcatCmd = "logcat -t 200 --pid " + android.os.Process.myPid() + " *:V";
                        Process process = Runtime.getRuntime().exec(logcatCmd);
                        InputStream input = process.getInputStream();
                        FileOutputStream out = context.openFileOutput("sentry_logcat.txt", Context.MODE_APPEND);
                        byte[] buffer = new byte[4096];
                        int bytesRead;
                        while ((bytesRead = input.read(buffer)) != -1) {
                            out.write(buffer, 0, bytesRead);
                        }
                        out.close();
                        input.close();
                        hint.addAttachment(new Attachment(
                                context.getFilesDir().getPath() + "/sentry_logcat.txt",
                                "sentry_logcat.txt",
                                "text/plain"
                        ));
                    } catch (Exception e) {
                        Log.e("Sentry",e.getMessage());
                    }
                    return event;
                }
            })

@MrZhaobh it sounds like what you're after is this (which you can configure in the options):
