Question

将捕获图像上传到Firebase时出现此错误。我在一个教程中看到这可能是因为我的手机，但我对此表示高度怀疑。奇怪的是，如果将其添加到Bitmap，则可以显示图像。从URI上载时出现错误的我。

错误：

声明：

private StorageReference mStorage;
mStorage = FirebaseStorage.getInstance().getReference();

我要捕获的代码：

 private void showImageChosen() {
    Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
    startActivityForResult(takePictureIntent, CHOOSE_IMAGE);
}

我要上传到firebase的代码：

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (requestCode == CHOOSE_IMAGE && resultCode == RESULT_OK) {

            Uri uri = data.getData();

            StorageReference filepath = mStorage.child("PictureTest").child("" + System.currentTimeMillis());

            filepath.putFile(uri).addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
                @Override
                public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {

                }
            }).addOnFailureListener(new OnFailureListener() {
                @Override
                public void onFailure(@NonNull Exception e) {

                }
            });

    }
}

尝试一下：

std::forward

在上传到Firebase期间，Uri和getData为空对象
