Firebase storage,relatime database android :User does not have permission to access this object

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 the message User does not have permission to access this object. What should I do?
This answer does not help me.

}
}

Since I have seen a comment in your code that sounds like this "Allow access by all users", then I recommend you use the following rules:
rules_version = '2';
service firebase.storage {
match /b/{bucket}/o {
match /{allPaths=**} {
allow read, write;
}
}
}
For testing purposes, it will work but I encourage you to change them when you'll launch the application.

Unable to share images in android project chat applicaton

I tried to share the image in my chat application. But was not able to successfully share it. It's selecting the image from the gallery but not appearing in the Userchat screen and not getting upload in the firebase also.
I am not able to find the solution for it. I would very much appreciate if someone can help me out.

Store that image URL in your chat.
You can do something like this, I am giving you an example for firebase realtime database:
#Override
protected void onActivityResult(int requestCode, int resultCode, #Nullable Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == 438 && resultCode == RESULT_OK && data != null && data.getData() != null) {
// you should show some progress dialog or progress bar here for better user experience.
progressDialog.show()
fileUri = data.getData();
if (checker.equals("image")) {
StorageReference storageReference = FirebaseStorage.getInstance().getReference().child("Image files");
final String messgSenderRef = "Messages/" + mAuth.getCurrentUser().getUid() + "/" + userId;
final String messgReceiverRf = "Messages/" + userId + "/" + mAuth.getCurrentUser().getUid();
DatabaseReference messageRef = databaseReference.child("Messages").child(mAuth.getCurrentUser().getUid()).child(userId).push();
final String messagePushId = messageRef.getKey();
final StorageReference filepath = storageReference.child(messagePushId + "." + "jpg");
filepath.putFile(fileUri).addOnProgressListener(new OnProgressListener<UploadTask.TaskSnapshot>() {
#Override
public void onProgress(#NonNull UploadTask.TaskSnapshot taskSnapshot) {
// you can show progress of upload here, let suppose you have a progressDialog then:-
double p = ((double) 100 * taskSnapshot.getBytesTransferred()) / taskSnapshot.getTotalByteCount();
progressDialog.setMessage((int) p + "%" + " Uploading....");
}
}).continueWithTask(new Continuation<UploadTask.TaskSnapshot, Task<Uri>>() {
#Override
public Task<Uri> then(#NonNull Task<UploadTask.TaskSnapshot> task) throws Exception {
if (!task.isSuccessful()) {
throw task.getException();
}
return filepath.getDownloadUrl();
}
}).addOnCompleteListener(new OnCompleteListener<Uri>() {
#Override
public void onComplete(#NonNull Task<Uri> task) {
if (task.isSuccessful()) {
progressDialog.dismiss();
// Now you have Uri of your image
downloadUri = task.getResult().toString();
Map<String, Object> messageTextBody = new HashMap<>();
messageTextBody.put("message", downloadUri);
messageTextBody.put("name", fileUri.getLastPathSegment());
messageTextBody.put("type", fileStatus);
messageTextBody.put("from", mAuth.getCurrentUser().getUid());
messageTextBody.put("to", userId);
messageTextBody.put("messageId", messagePushId);
messageTextBody.put("time", saveCurrentTime);
messageTextBody.put("date", saveCurrentDate);
Map<String, Object> messageBodydetails = new HashMap<>();
// add message to sender and receiver's
messageBodydetails.put(messgSenderRef + "/" + messagePushId, messageTextBody);
messageBodydetails.put(messgReceiverRf + "/" + messagePushId, messageTextBody);
databaseReference.updateChildren(messageBodydetails).addOnCompleteListener(new OnCompleteListener<Void>() {
#Override
public void onComplete(#NonNull Task<Void> task) {
if (task.isSuccessful()) {
editText.setText("");
}
}
});
} else {
Toast.makeText(ChatActivity.this, "Error: " + task.getException().getMessage(), Toast.LENGTH_SHORT).show();
progressDialog.dismiss();
}
}
});
} else {
}
}
}
Then in the chat you can check for the changes in the database in realtime and update your chat's recycler view in realtime. Just specify the chat message type to identify and display the view accordingly. If the chat type is text, show the text message. If the chat type is an image, load an image from the URL you have stored.

How do I store downloadUrl of multiple images to the Firebase Firestore ? Unable to create and store inside multiple fields inside Firestore document

Here's what I have been able to get so far. After selecting the images
selectImageButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if(mUploadTask != null && mUploadTask.isInProgress()){
Toast.makeText(MainActivity.this, "Upload In Progress", Toast.LENGTH_SHORT).show();
}
else {
Intent intent = new Intent();
intent.setType("image/*");
intent.putExtra(Intent.EXTRA_ALLOW_MULTIPLE, true);
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent, "Select Picture"), RESULT_LOAD_IMAGE);
}
}
});
Inside the OnActivityResult, I am uploading my selected Images to the Firebase Storage and at the same time I want to store my download Urls of those multiple images to the Firebase Firestore
protected void onActivityResult(int requestCode, int resultCode, #Nullable Intent data) {
super.onActivityResult(requestCode, resultCode, data);
String fileName;
final String[] downloadUrl = new String[1];
if(requestCode == RESULT_LOAD_IMAGE && resultCode == RESULT_OK){
if(data.getClipData() != null){
int totalItemsSelected = data.getClipData().getItemCount();
for(int i =0;i<totalItemsSelected;i++){
Uri fileUri = data.getClipData().getItemAt(i).getUri();
fileName = getFileName(fileUri);
fileNameList.add(fileName);
fileDoneList.add("uploading");
uploadListAdapter.notifyDataSetChanged();
final StorageReference fileToUpload = storageReference.child("Images").child(fileName);
final int finalI = i;
final int totalCount = totalItemsSelected;
mUploadTask = fileToUpload.putFile(fileUri).addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
#Override
public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
fileToUpload.getDownloadUrl().addOnSuccessListener(new OnSuccessListener<Uri>() {
#Override
public void onSuccess(Uri uri) {
String url = String.valueOf(uri);
storeLink(url,totalCount);//Method To Store the Url
}
});
// Toast.makeText(add_for_sale.this, "Uploading works", Toast.LENGTH_SHORT).show();
fileDoneList.remove(finalI);
fileDoneList.add(finalI,"done");
uploadListAdapter.notifyDataSetChanged();
}
});
// ImageUploadInfo imageUploadInfo = new ImageUploadInfo(downloadUrl[0],fileName);
}
Toast.makeText(this, "Upload in Progress", Toast.LENGTH_SHORT).show();
}
else if(data.getData() != null){
Toast.makeText(this, "Selected Single", Toast.LENGTH_SHORT).show();
}
}
}
In the method storeLink(url,totalCount), I am creating a map object to create field "imageUrl" inside the document,where "29t0Boxm0fa8UNkomuo5xPLwkx13" is a user id.
private void storeLink(final String url,final int totalCount) {
FirebaseFirestore storeUrl = FirebaseFirestore.getInstance();
Toast.makeText(MainActivity.this, url, Toast.LENGTH_LONG).show();
for (int i=0;i<totalCount;i++) {
final Map<String, Object> image = new HashMap<>();
image.put("imageUrl"+i, url);
DocumentReference documentReference = storeUrl.collection("users").document("29t0Boxm0fa8UNkomuo5xPLwkx13");
documentReference.set(image).addOnSuccessListener(new OnSuccessListener<Void>() {
#Override
public void onSuccess(Void aVoid) {
Log.d(TAG, "" +
"OnSuccess : Image Link Saved ");
// startActivity(new Intent(Register.this,LoginActivity.class));
}
}).addOnFailureListener(new OnFailureListener() {
#Override
public void onFailure(#NonNull Exception e) {
Log.d(TAG, "OnFailure : " + e.toString());
}
});
}
}
Storage Rules
rules_version = '2'
service firebase.storage {
match /b/{bucket}/o {
match /{allPaths=**} {
allow read, write: if true;
}
}
Firestore Rules
rules_version = '2';
service cloud.firestore {
match /databases/{database}/documents {
match /{document=**} {
allow read, write: if true;
}
}
}

Make sure you have made final to Map<String,Object> user = new HashMap<>();
And add user.put("key","value") inside the loop.
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
final DocumentReference documentReference = db.collection("users").document("multi_image");
final Map<String, Object> user = new HashMap<>();
if (requestCode == RESULT_LOAD_IMAGE && resultCode == RESULT_OK) {
if (data.getClipData() != null) {
final int totalItemsSelected = data.getClipData().getItemCount();
for (int i = 0; i < totalItemsSelected; i++) {
Uri fileUri = data.getClipData().getItemAt(i).getUri();
final int x = i;
final StorageReference fileToUpload = mStorageRef.child("Images").child("" + x);
fileToUpload.putFile(fileUri)
.addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
#Override
public void onSuccess(final UploadTask.TaskSnapshot taskSnapshot) {
Task<Uri> DownloadURL = taskSnapshot.getStorage().getDownloadUrl();
DownloadURL.addOnSuccessListener(new OnSuccessListener<Uri>() {
#Override
public void onSuccess(Uri uri) {
user.put("image_" + x, uri.toString());
Log.v("users", "" + user);
documentReference.update(user)
.addOnSuccessListener(new OnSuccessListener<Void>() {
#Override
public void onSuccess(Void aVoid) {
Log.v("task", "Success");
}
})
.addOnFailureListener(new OnFailureListener() {
#Override
public void onFailure(#NonNull Exception e) {
Log.v("failed", "" + e);
}
});
}
});
}
});
}
Toast.makeText(this, "Upload in Progress", Toast.LENGTH_SHORT).show();
} else if (data.getData() != null) {
Toast.makeText(this, "Selected Single", Toast.LENGTH_SHORT).show();
}
}
super.onActivityResult(requestCode, resultCode, data);
}
Firebase Storage https://i.stack.imgur.com/HeYvh.png
Firebase Database https://i.stack.imgur.com/3t2aN.png

Here's what worked out for me finally :
Create an ArrayList variable globally
ArrayList<String> imageList;
Then initialize this ArrayList inside the
onActivityResult as imageList = new ArrayList<>(totalItemsSelected); as mentioned inside the code below
#Override
protected void onActivityResult(int requestCode, int resultCode, #Nullable Intent data) {
super.onActivityResult(requestCode, resultCode, data);
String fileName;
if(requestCode == RESULT_LOAD_IMAGE && resultCode == RESULT_OK){
if(data.getClipData() != null){
progressBar.setVisibility(View.VISIBLE);
final int totalItemsSelected = data.getClipData().getItemCount();
count = totalItemsSelected;
imageList = new ArrayList<>(totalItemsSelected);
StorageReference ImageFolder = FirebaseStorage.getInstance().getReference().child("ImageFolder");
for(int i =0;i<totalItemsSelected;i++){
Uri fileUri = data.getClipData().getItemAt(i).getUri();
fileName = getFileName(fileUri);
fileNameList.add(fileName);
fileDoneList.add("uploading");
uploadListAdapter.notifyDataSetChanged();
final StorageReference fileToUpload = ImageFolder.child(fileName);
final int finalI = i;
mUploadTask = fileToUpload.putFile(fileUri).addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
#Override
public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
progressBar.setVisibility(View.INVISIBLE);
fileToUpload.getDownloadUrl().addOnSuccessListener(new OnSuccessListener<Uri>() {
#Override
public void onSuccess(Uri uri) {
String url = String.valueOf(uri);
imageList.add(url);
// Toast.makeText(add_for_sale.this, imageList.get(finalI), Toast.LENGTH_SHORT).show();
Log.i(TAG,"Added To List");
}
});
fileDoneList.remove(finalI);
fileDoneList.add(finalI,"done");
uploadListAdapter.notifyDataSetChanged();
}
});
}
Toast.makeText(this, "Upload in Progress", Toast.LENGTH_SHORT).show();
}
else if(data.getData() != null){
Toast.makeText(this, "Select Two or More Images", Toast.LENGTH_SHORT).show();
}
}
}
Now to Save the Url Links to the Firebase Firestore Add the links to the ArrayList as imageList.add(url;)
and upload this list imageList to the FireStore as
Map<String,Object> imageUrl = new HashMap<>();
imageUrl.put("ImageUrl", imageList);
String userId;
userId = firebaseUser.getUid();
firebaseFirestore.collection("ImageDetails").document(userId)
.set(imageUrl,SetOptions.merge());
This will create an array of ImageUrl inside your firestore document

image taken from gallery is unable to set in image view

I am taking image from camera as well as from gallery,after getting the image, I want to show the image in imageview.
Image that is captured by camera successfully is shown in imageview but when I want to select it from gallery it does not show the image and it also does not show any error. It was working properly but later I add camera feature in activity, it's not working well.

selectedImage = BitmapFactory.decodeStream(imageStream);
You should check if selectedImage -the bitmap- is null.
I bet selectedImage==null.
This happens if the bitmap would become too big for available memory.
You should scale it down while loading from stream.
Remember: from the camera you only obtain a thumbnail. Thats the difference.

In your code, try to add createScaledBitmap to resize your photo like this:
if (requestCode == REQUEST_IMAGE_CAPTURE && resultCode == RESULT_OK) {
Bundle extras = data.getExtras();
Bitmap imageBitmap = (Bitmap) extras.get("data");
//add this line and use the new bitmap resized
Bitmap imageBitmapResized = Bitmap.createScaledBitmap(imageBitmap , 120, 120, false);
iv.setImageBitmap(imageBitmapResized );
image = encode(imageBitmapResized );//this line is added to encode
} else if (requestCode == PHOTO_FROM_MEMORY_REQUESTED && resultCode == RESULT_OK) {
updateSelectedPicture(data.getData());
}

Class variable not changing in IF or Switch statements

Seems simple, but I can't get it to work. I have a public class string variable that should change within a if or switch statement. I haven't declared the variable inside the statement so it should change given the scope, no? But it only reads "FROM" and when I do go to change it in the if statement that applies, it does change to "TO" but only in that instance and reverts back to "FROM". I would pass it along the methods, but the full code is more cluttered and I don't think it's possible to do so.

String typeOfText = "FROM";

The reason the code keeps reverting is because the call to readImage() is in onActivityResult() which recreates the activity when called. So basically, you are getting a fresh object, and the onTypeText() is reinitialized. onActivityResult() is basically a callback from your previous activity.

Your onClick() is not being called due you don't assign clicklistener to R.id.faboptions_favorite and the other View
in onCreate add :
findViewById(R.id.faboptions_favorite).setOnClickListener(this);
and same for the other view.
