May the root cause of this crash is MyTracks missing a branch(doWriteTrack() 
method of TrackWriterImpl.java) when open file failed. 
As following shows:

line 104:
  private void doWriteTrack() {
    // Open the input and output
    success = false;
    errorMessage = R.string.external_storage_save_error;
    if (track != null) {
      if (openFile()) {
       ....
      }
      // Here need a else branch 
    }
  }
