  73.             }
  74.         }, 1000);
  75.     }
  76. }

in the upper code addOnSuccessListener is not working

  1. ImageName.putFile(IndividualImage).addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
  2.     @Override
  3.     public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
  4.         ImageName.getDownloadUrl().addOnSuccessListener(new OnSuccessListener<Uri>() {
  5.             @Override
  6.             public void onSuccess(Uri uri) {
  7.                 String URL = String.valueOf(uri);
  8.                 hashMap.put("image_url" + upload_count, URL);
  9.             }
  10.         });
  11.     }
  12. }).addOnFailureListener(new OnFailureListener() {
  13.     @Override
  14.     public void onFailure(@NonNull Exception e) {
  15.         Toast.makeText(activity, "failed", Toast.LENGTH_SHORT).show();
  16.     }
  17. });

please anyone knows the solution, please tell me. THANKS IN ADVANCE...

  4. # 答案1
  5. **得分**: 0
  6. 我解决了这个错误。我忘记将存储规则更新为公开。
  7. ****
  8. 上面的代码是没有错误的代码...所以，你可以使用这段代码来在Firebase存储上上传多张图片。***但是，不要忘记检查Firebase规则***，我在下面添加了规则。
  9. ****
  10. **Firebase存储规则**
  11. ```firebase存储规则
  12. rules_version = '2';
  13. service firebase.storage {
  14. match /b/{bucket}/o {
  15. match /{allPaths=**} {
  16. allow read, write;
  17. }
  18. }
  19. }```
  20. <details>
  21. <summary>英文:</summary>
  22. **I solved the error. I forgot to update storage rules to public.**
  23. ****
  24. upper code is error free code... so, you can use this code for upload multiple images on firebase storage. ***but, dont forget to check the firebase rules***, I am adding rules below.
  25. ****
  26. **firebase storage rules**

rules_version = '2';
service firebase.storage {
match /b/{bucket}/o {
match /{allPaths=**} {
allow read, write;
}
}
}

  2. </details>
