WARNING: File.mkdir() is ignored

Question

I've created a basic Audio Recording App using Media Recorder API's. I'm trying to create a folder in the SD card and to save my recorded files to that folder. I'm getting this warning with following code.

File.mkdir() is ignored

    // Assign random number to avoid audio file from overwriting
    Long tsLong = System.currentTimeMillis()/1000;

    // Specify a Location for the recorded file to be stored in the SD card
    mFileName = Environment.getExternalStorageDirectory().getAbsolutePath() + "/AudioRecordTest/";
    File path = new File(mFileName);
    if(!path.exists()) {
        path.mkdir();
    }
    mFileName += "/AudioRecordTest_" + tsLong.toString() + ".mp3";

How to solve this warning message. Feel free to modify the code if there is any other mistake.

Answer 1

As @Stephen C suggests, i handled in these ways

1)

boolean isDirectoryCreated= path.mkdir();

and ignore 'isDirectoryCreated'

2) (Recommended)

 boolean isDirectoryCreated=path.exists();
 if (!isDirectoryCreated) {
     isDirectoryCreated= path.mkdir();
 }
 if(isDirectoryCreated) {
    // do something
 }

3)

if (!path.exists()) {
   if(path.mkdir()){
     // do something
   }
}
