Failed to create recording file under certain circumstances

[hujiejeff]

If you create a recording file with the same name as a folder in that directory, you will be unable to create the recording file
f.exists() && !f.isDirectory() has problem in RecordingService.java

public void setFileNameAndPath(boolean isFilePathTemp) {
        if (isFilePathTemp) {
            mFileName = getString(R.string.default_file_name) + (++tempFileCount) + "_" + ".tmp";
            mFilePath = Paths.combine(
                    Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_MUSIC),
                    Paths.SOUND_RECORDER_FOLDER, mFileName);
        } else {
            int count = 0;
            File f;

            do {
                ++count;

                mFileName =
                        getString(R.string.default_file_name) + "_" + (mDatabase.getCount() + count) + ".mp4";

                mFilePath = Paths.combine(
                        Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_MUSIC),
                        Paths.SOUND_RECORDER_FOLDER, mFileName);

                f = new File(mFilePath);
            } while (f.exists() && !f.isDirectory());//Bug in here
        }
    }
