I know you guys can help me on this. Been going through every related topic on SOF and also referred to Firebase docs, but still need some help.
Just like the docs are pointing out I am trying to get url through getDownloadUrl() with success completion. But it still returns a task which looks like 'com.google.android.gms.tasks.zzu@f470008'.
UPDATE:
In this fragment, i am trying to upload a Post object to Firebase Database. Everything works fine except the image url and just like the Docs are pointing out, taskSnapshot.getDownloadUrl() no longer works. The method getDownloadUrl() needs to be attached to a success completion. But in my case firebase still returns a task instead of url.
I've gone through all the related questions but my problem seems more different.
Here's the whole code from my Fragment;
public class PostFragment extends Fragment implements SelectPhotoDialog.OnPhotoSelectedListener{
private static final String TAG = "PostFragment";
private FrameLayout parentFrameLayout;
private FirebaseFirestore firebaseFirestore;
ImageLoader imageLoader = ImageLoader.getInstance(); // Get singleton instance
@Override
public void getImagePath(Uri imagePath) {
Log.d(TAG, "getImagePath: setting the image to imageview");
Glide.with(this).load(imagePath.toString()).into(mPostImage);
//imageLoader.displayImage("", mPostImage);
mSelectedBitmap = null;
mSelectedUri = imagePath;
}
@Override
public void getImageBitmap(Bitmap bitmap) {
Log.d(TAG, "getImageBitmap: setting the image to imageview");
mPostImage.setImageBitmap(bitmap);
mSelectedUri = null;
mSelectedBitmap = bitmap;
}
//widgets
private ImageView mPostImage;
private EditText mTitle, mDescription, mPrice, mCountry, mStateProvince, mCity, mContactEmail;
private Button mPost;
private ProgressBar mProgressBar;
//vars
private Bitmap mSelectedBitmap;
