我面临着一个OutOfMemoryError，而写的文件是不可复制的每一次，但它经常发生的少数用户，我得到了下面的错误，而检查日志。

2023-05-03 12:11:11.257 6986-6986/com.example.dev E/AndroidRuntime: FATAL EXCEPTION: main Process: com.example.dev, PID: 6986 java.lang.OutOfMemoryError: Failed to allocate a 265048 byte allocation with 96648 free bytes and 94KB until OOM, max allowed footprint 201326592, growth limit 201326592 at java.util.Arrays.copyOf(Arrays.java:3260)

而这种错误正在无限地发生。下面提到的代码指出了问题所在。

private fun writeFile(tag: String, msg: String, exception: Throwable?) {
    try {
        if (logFileOutputStream != null) {
            logFileOutputStream.write(formatLog(msg).toByteArray())
            logFileOutputStream.flush()
        }
    } catch (e: IOException) {
        debug(TAG, "Error in writing log i.e.($msg) to file " + e.message)
    }
}

private fun formatLog(msg: String): String {
    val dateTime: String =
        DateFormatterUtility.formatDateTimeToString(Date(), "MM/dd/yyyy HH:mm:ss.SSS")
    return "$dateTime : $msg \n"
}
