How to use getdownloadurl in recent versions?（3个答案）

已关闭1分钟前。

对于我在聊天室com.google.android.gms.tasks.zzu@d55ef5中发送的每张图像，这都会返回我>

以下是我的代码：

@Override
    protected void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) {
        super.onActivityResult(requestCode, resultCode, data);

        if (requestCode == 1 && resultCode == RESULT_OK){
            Uri uriImagen = data.getData();
            storageReference = storage.getReference("chat_images");//El nombre de la carpeta en la que voy a guardar las imagenes
            final StorageReference photoReference = storageReference.child(uriImagen.getLastPathSegment()); //Obtenemos como un id de la imagen que la diferencia de todas las demás
            photoReference.putFile(uriImagen).addOnSuccessListener(this, new OnSuccessListener<UploadTask.TaskSnapshot>() {
                @Override
                public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
                    String urlPhoto = taskSnapshot.getMetadata().getReference().getDownloadUrl().toString();

                    Log.v("Url de la foto", urlPhoto);

                    Message m = new Message(tvName.getText().toString() + " te ha enviado una foto", urlPhoto, tvName.getText().toString(), "", "2", "00:00");
                    databaseReference.push().setValue(m);
                }
            });
        }
    }

需要帮助..提前感谢

您可以改用Task<Uri>，请尝试一下。通过不建议使用此getMetadata().getReference().getDownloadUrl()，建议您阅读此Upload-files firebase

photoReference.putFile(uriImagen).addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
        @Override
        public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
            Task<Uri> downloadUri = taskSnapshot.getStorage().getDownloadUrl();

           if(downloadUri.isSuccessful()){
            String urlPhoto = downloadUri.getResult().toString();
            Log.v("Url de la foto", urlPhoto);
            Message m = new Message(tvName.getText().toString() + " te ha enviado una foto", urlPhoto, tvName.getText().toString(), "", "2", "00:00");
                    databaseReference.push().setValue(m);
        }}
    })
    .addOnFailureListener(new OnFailureListener() {
        @Override
        public void onFailure(@NonNull Exception e) {
            //Do whatever you want                     
        }
    });

尝试此代码：
public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {

            Task<Uri> downloadUrl = taskSnapshot.getStorage().getDownloadUrl();
            downloadUrl.addOnCompleteListener(new OnCompleteListener<Uri>() {
                @Override
                public void onComplete(@NonNull Task<Uri> task) {
                    Log.v(TAG, "Media is uploaded");

                    String downloadURL = "https://" + task.getResult().getEncodedAuthority()
                            + task.getResult().getEncodedPath()
                            + "?alt=media&token="
                            + task.getResult().getQueryParameters("token").get(0);

                    Log.v(TAG, "downloadURL: " + downloadURL);
                    //save your downloadURL
                }
            });
        }

Answer 2

尝试此代码：

public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {

            Task<Uri> downloadUrl = taskSnapshot.getStorage().getDownloadUrl();
            downloadUrl.addOnCompleteListener(new OnCompleteListener<Uri>() {
                @Override
                public void onComplete(@NonNull Task<Uri> task) {
                    Log.v(TAG, "Media is uploaded");

                    String downloadURL = "https://" + task.getResult().getEncodedAuthority()
                            + task.getResult().getEncodedPath()
                            + "?alt=media&token="
                            + task.getResult().getQueryParameters("token").get(0);

                    Log.v(TAG, "downloadURL: " + downloadURL);
                    //save your downloadURL
                }
            });
        }
