Question

我正确上传了文件，现在我要下载，没有错误，但logcat表示下载已完成，但是我无法在手机存储器中找到文件其他版本的代码会产生错误

代码：

 public void download(){
    try{
        //DatabaseReference databaseReference= FirebaseDatabase.getInstance().getReference();
        FirebaseStorage storage = FirebaseStorage.getInstance();
    //StorageReference storageRef = storage.getReferenceFromUrl(url);

    final StorageReference storageRef = storage
            .getReferenceFromUrl("gs://the-piraty-book-alpha1.appspot.com/arquivos/")
            .child(nome);

        File storagePath = new File( Environment.getExternalStorageDirectory(),"TPB");
        if(!storagePath.exists()) {
            storagePath.mkdirs();
        }

        File localFile = null;
        localFile = File.createTempFile("arquivo","pdf");

        final File finalLocalFile = localFile;
        FileDownloadTask task = storageRef.getFile(localFile);
        task.addOnSuccessListener(new OnSuccessListener<FileDownloadTask.TaskSnapshot>() {
            @Override
            public void onSuccess(FileDownloadTask.TaskSnapshot taskSnapshot) {
                Log.e("firebase ",";local tem file created  created " + finalLocalFile.toString());

            }
        }).addOnFailureListener(new OnFailureListener() {
            @Override
            public void onFailure(@NonNull Exception exception) {
                Log.e("firebase ",";local tem file not created  created " +exception.toString());
            }
        });

    }catch (IOException e){

    }
}
