User does not have permission to access this object . Firebase storage android

Question

I am new to firebase storage. Just so I could learn it, I made a simple app that has a button and an ImageView. When I click on the button, an image (from drawable) gets displayed on the ImageView. I have also written the code for uploading the image on Firebase, but the exception message of onAddFailureListener gives message User does not have permission to access this object. What should I do ?

package com.example.asad.save_photo;  import android.app.Activity; import android.graphics.Bitmap; import android.os.Bundle; import android.net.Uri; import android.os.Environment; import android.support.annotation.NonNull; import android.support.v7.app.AppCompatActivity; import android.os.Bundle; import android.view.View; import android.widget.Button; import android.widget.ImageView; import android.widget.Toast;  import com.google.android.gms.tasks.OnFailureListener; import com.google.android.gms.tasks.OnSuccessListener; import com.google.firebase.storage.FirebaseStorage; import com.google.firebase.storage.StorageMetadata; import com.google.firebase.storage.StorageReference; import com.google.firebase.storage.UploadTask;  import java.io.ByteArrayOutputStream; import java.io.File;  public class MainActivity extends AppCompatActivity {      @Override     protected void onCreate(Bundle savedInstanceState) {         super.onCreate(savedInstanceState);         setContentView(R.layout.activity_main);         FirebaseStorage storage = FirebaseStorage.getInstance();          StorageReference storageRef = storage.getReferenceFromUrl("gs://savephoto-a1cc3.appspot.com");          final StorageReference mountainsRef = storageRef.child("asad");          Button butt = (Button) findViewById(R.id.button);           butt.setOnClickListener(new View.OnClickListener() {             @Override             public void onClick(View v) {                  ImageView imageView = (ImageView) findViewById(R.id.image);                 imageView.setImageResource(R.drawable.back2);                 //imageView.setImageResource(R.drawable.back2);                  imageView.setDrawingCacheEnabled(true);                 imageView.buildDrawingCache();                 Bitmap bitmap = imageView.getDrawingCache();                   ByteArrayOutputStream baos = new ByteArrayOutputStream();                 bitmap.compress(Bitmap.CompressFormat.JPEG, 100, baos);                 final byte[] data = baos.toByteArray();                  UploadTask uploadTask = mountainsRef.putBytes(data);                 uploadTask.addOnFailureListener(new OnFailureListener() {                     @Override                     public void onFailure(@NonNull Exception exception) {                         // Handle unsuccessful uploads                         showToast(exception.getMessage());                     }                 });                         uploadTask.addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {                     @Override                     public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {                         // taskSnapshot.getMetadata() contains file metadata such as size, content-type, and download URL.                         //Uri downloadUrl = taskSnapshot.getDownloadUrl();                         showToast("success !!!!!");                     }                 });               }         });      }      public void showToast(String s) {         Toast.makeText(this,s,Toast.LENGTH_LONG).show();     } } 

Here are my firebase storage rules

service firebase.storage {   match /b/savephoto-a1cc3.appspot.com/o {     allow read,write;   } }

Update your security rules with match /{allPaths=**} to indicate that public read and write access is allowed on all paths:

service firebase.storage {   match /b/savephoto-a1cc3.appspot.com/o {     match /{allPaths=**} {       // Allow access by all users       allow read, write;     }   } } 

Various default rules are provides in the tabs of the Sample Rules section of the documentation.
