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

Question

I am new to firebase repository. Just so that I can learn it, I created a simple program that has a button and ImageView . When I click on the button, the image (from drawable) displayed in the ImageView. I also wrote code to upload the image to Firebase, but the onAddFailureListener exception onAddFailureListener gives the message The 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; } } 

Answer 1

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; } } } 

The bookmarks in the Example Rules section contain various default rules.

Answer 2

Change retention rules in Firebase console

 service firebase.storage { match /b/{bucket}/o { match /{allPaths=**} { allow read, write: if request.auth != null; } } } 

Answer 3

Just go to Storage - Rules. Enter the rule as follows, replacing the bucket name with your own bucket name. You can find the name of the bucket by going to Storage-Files.

It should look something like this: myapplication-xxxx.appspot.com

That is all you need. You do not need to enable authentication if you only do this for testing. If you need authentication, you can add it later.

Answer 4

Go to repository → Rules tab

Add this

 // Anyone can read or write to the bucket, even non-users of your app. // Because it is shared with Google App Engine, this will also make // files uploaded via GAE public. service firebase.storage { match /b/{bucket}/o { match /{allPaths=**} { allow read, write; } } } 

Answer 5

These solutions really did not solve my problem.

what solved my problem was the following lines:

in the application module

 implementation 'com.google.firebase:firebase-database:15.0.0' implementation 'com.google.firebase:firebase-storage:15.0.0' implementation 'com.google.firebase:firebase-auth:15.0.0' 

and this code to download and get the download link

 private void uploadImageToFirebase(Bitmap bmp) { try { String file_path = Environment.getExternalStorageDirectory().getAbsolutePath() + "/news"; File dir = new File(file_path); if (!dir.exists()) dir.mkdirs(); File file = new File(dir, "sketchpad" + "_" + ".png"); FileOutputStream fOut = new FileOutputStream(file); bmp.compress(Bitmap.CompressFormat.PNG, 100, fOut); fOut.flush(); fOut.close(); Log.i("SECONDACTIVITY", "ADDED SUCCESSFULLY"); Uri file2 = Uri.fromFile(file); //Now Upload final StorageReference storageRef = FirebaseStorage.getInstance().getReference(); StorageReference riversRef = storageRef.child(file.getName()); UploadTask uploadTask; uploadTask = riversRef.putFile(file2); progressDialog.show(); progressDialog.setCancelable(false); uploadTask.addOnProgressListener(new OnProgressListener<UploadTask.TaskSnapshot>() { @Override public void onProgress(UploadTask.TaskSnapshot taskSnapshot) { double progress = (100.0 * taskSnapshot.getBytesTransferred()) / taskSnapshot.getTotalByteCount(); progressDialog.incrementProgressBy((int) progress); } }); uploadTask.addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() { @Override public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) { progressDialog.dismiss(); Uri DownloadLink = taskSnapshot.getDownloadUrl(); String imgUrl = DownloadLink.toString(); FirebaseDatabase.getInstance().getReference().child("image_link").setValue(imgUrl); } }); uploadTask.addOnFailureListener(new OnFailureListener() { @Override public void onFailure(@NonNull Exception e) { progressDialog.dismiss(); } }); } catch (IOException e) { e.printStackTrace(); } } 

Answer 6

 service firebase.storage { match /b/fir-upload-a2fa6.appspot.com/o { match /{allPaths=**} { // Allow access by all users allow read, write; } } }
