how do I get file size of temp file in android?

Question

if I use openFileOutput() to create and write to a temp file how do I get filesize after I\'m done writing to it?

Answer 1

Try to use below code:

// Get file from file name
    final String dirPath = f.getAbsolutePath();
    String fileName = url.substring(url.lastIndexOf('/') + 1);
    File file = new File(dirPath + "/" + fileName);

      // Get length of file in bytes
          long fileSizeInBytes = file.length();
     // Convert the bytes to Kilobytes (1 KB = 1024 Bytes)
          long fileSizeInKB = fileSizeInBytes / 1024;
    //  Convert the KB to MegaBytes (1 MB = 1024 KBytes)
          long fileSizeInMB = fileSizeInKB / 1024;

          if (fileSizeInMB > 27) {
          ...
          }

Hope It will work for you..!!
