Develop Reference

setValue() doesn't work with Model Activity

I am trying to figure out what is wrong with my code and no data is uploaded in FirebaseDatabase. When I press the post button image url is getting in FirebaseStorage but the rest data does not appear in my database. Here is the code:

Well, I checked whether there was a problem with my database rules but nothing seems wrong, both "read" and "write" are turned "true". I also tried to delete my Firebase project and create a new one but the same problem was still there.

How to retrieve latest entry from the firebase realtime database?

I am trying to take inputs from one user and send the same data to another user. I am not sure what to put as an argument in child so that it refers to the same data and I can retrieve and show the data to another user for approval. I am able to send the image but for the data fields like visitor,mobile and flat not sure what to do.
My code is as follows.

In your Main5Activity, I think:
This:
for(DataSnapshot child: dataSnapshot.getChildren()) {
String post = dataSnapshot.child("visitor").getValue(String.class);
String post1 = dataSnapshot.child("mobile").getValue(String.class);
String post2 = dataSnapshot.child("flat").getValue(String.class);
textView.setText("Mr. "+post+"with mobile number: " + post1+"wants to visit your flat: " + post2);
}
Must be like this:
for(DataSnapshot ds: dataSnapshot.getChildren()) {
String post = ds.child("visitor").getValue(String.class);
String post1 = ds.child("mobile").getValue(String.class);
String post2 = ds.child("flat").getValue(String.class);
textView.setText("Mr. "+post+"with mobile number: " + post1+"wants to visit your flat: " + post2);
}

I want to store image in real-time database

You can request download URL for the file after uploading finishes.
Then Add the URL to Real-time Database
reference.putFile(filepath).addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
#Override
public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
progressDialog.dismiss();
Toast.makeText(MainActivity.this, "Image uploaded", Toast.LENGTH_SHORT) .show();
reference.getDownloadUrl().addOnSuccessListener(new OnSuccessListener<Uri>() {
#Override
public void onSuccess(Uri uri) {
//You will get donwload URL in uri
Log.d(TAG, "Download URL = "+ uri.toString());
//Adding that URL to Realtime database
mDatabase.child("imageUrl").setValue(uri.toString());
}
});
}
})

#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if(requestCode == PICK_IMAGE_REQUEST && resultCode == RESULT_OK
&& data != null && data.getData() != null )
{
filePath = data.getData();
try {
Bitmap bitmap = MediaStore.Images.Media.getBitmap(getContentResolver(), filePath);
imageView.setImageBitmap(bitmap);
}
catch (IOException e)
{
e.printStackTrace();
}
}
}
private void uploadImage() {
name = txtname.getText().toString();
if(filePath != null)
{
final ProgressDialog progressDialog = new ProgressDialog(this);
progressDialog.setTitle("Uploading...");
progressDialog.show();
StorageReference ref = storageReference.child("images/"+ name);
ref.putFile(filePath)
.addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
#Override
public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
progressDialog.dismiss();
Toast.makeText(MainActivity.this, "Uploaded", Toast.LENGTH_SHORT).show();
}
})
.addOnFailureListener(new OnFailureListener() {
#Override
public void onFailure(#NonNull Exception e) {
progressDialog.dismiss();
Toast.makeText(MainActivity.this, "Failed "+e.getMessage(), Toast.LENGTH_SHORT).show();
}
})
.addOnProgressListener(new OnProgressListener<UploadTask.TaskSnapshot>() {
#Override
public void onProgress(UploadTask.TaskSnapshot taskSnapshot) {
double progress = (100.0*taskSnapshot.getBytesTransferred()/taskSnapshot
.getTotalByteCount());
progressDialog.setMessage("Uploaded "+(int)progress+"%");
}
});
}
Toast.makeText(this, name, Toast.LENGTH_SHORT).show();

How to upload and retrieve image with Picasso

I want to upload my picture into my image into my database and save it as a url and then call it to my circle image view as a profile picture. But it's not being saved as a url and it's not showing up as a profile.
I have tried switching my code up. Invalidating and restarting android studio. Cleaning and rebuilding the project countless amounts of times. Wiped the data from my phone and my emulator. And I watched a bunch of videos and read answers here and elsewhere.

I want to upload the image into my Firebase database using an image URL and then display it in my circle image view as a profile picture.
EDIT !!
I uploaded that code and imported continuation but this is what I see now.
Code2

private void uploadImage() {
if(filePath != null)
{
final ProgressDialog progressDialog = new ProgressDialog(this);
progressDialog.setTitle("Uploading...");
progressDialog.show();
progressDialog.setCancelable(false);
final StorageReference ref = storageReference.child("images/"+ UUID.randomUUID().toString());
ref.putFile(filePath)
.addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
#Override
public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
progressDialog.dismiss();
Toast.makeText(AdminPanel.this, "Uploaded", Toast.LENGTH_SHORT).show();
// Upload upload=new Upload( databaseReference.child(cat_spinner.getSelectedItem().toString()).child(databaseReference.push().getKey()).setValue(taskSnapshot.))
ref.getDownloadUrl().addOnSuccessListener(new OnSuccessListener<Uri>() {
#Override
public void onSuccess(Uri uri) {
DatabaseReference url= databaseReference.child(cat_spinner.getSelectedItem().toString()).child(databaseReference.push().getKey());
Upload upload=new Upload( uri.toString());
url.setValue(upload);

I think the update should be like this:

{
Toast.makeText(SettingsActivity.this, "Profile pic upload successful", Toast.LENGTH_SHORT).show();

Upload Images to Firebase Storage and have a link in Firebase Database

I am currently working on an Incident Reporting application which allows users to choose and upload images.
I am already successful in posting images to Firebase Storage but I am wondering if it is possible to have a link/url in Firebase Database from which I can click to redirect me to Firebase Storage to see that image.
I want this function so that along with user inputs such as Title, Date, Remarks, the end-user would be able to see the "image" child with the link along with other inputs
I have tried searching StackOverflow and Youtube for answers but most of them are old and seem outdated. There is a command "getDownloadUrl" but i believe it has been deprecated.
This is the code from my class that uploads my image to Firebase Storage
private void uploadImage() {
if (filePath != null) {
final ProgressDialog progressDialog = new ProgressDialog(getActivity());
progressDialog.setTitle("Uploading...");
progressDialog.show();
StorageReference ref = storageReference.child("images/"+ UUID.randomUUID().toString());
ref.putFile(filePath)
.addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
#Override
public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
progressDialog.dismiss();
Toast.makeText(getActivity(),"Uploaded", Toast.LENGTH_SHORT).show();
}
})
.addOnFailureListener(new OnFailureListener() {
#Override
public void onFailure(#NonNull Exception e) {
progressDialog.dismiss();
Toast.makeText(getActivity(),"Failed"+e.getMessage(), Toast.LENGTH_SHORT).show();
}
})
.addOnProgressListener(new OnProgressListener<UploadTask.TaskSnapshot>() {
#Override
public void onProgress(UploadTask.TaskSnapshot taskSnapshot) {
double progress = (100.0*taskSnapshot.getBytesTransferred()/taskSnapshot.getTotalByteCount());
progressDialog.setMessage("Uploaded"+(int)progress+"%");
}
});
}
}
private void chooseImage() {
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent,"Select Picture"),PICK_IMAGE_REQUEST);

Any help or tutorials is greatly appreciated!
Database Inputs (not including image)

For storing the images to your Firebase Storage, you first set a correct reference and just store the image there, very similar to Firebase Database data storing.
To have a link in the Firebase Database, you can just use downloadUri you can get from storage and have it stored in the database.
The code for this looks something like this, you can take an inspiration from this and come up with a code that suits you more:
private void uploadFile(Bitmap bitmap) {
FirebaseStorage storage = FirebaseStorage.getInstance();
final StorageReference storageRef = storage.getReference();
final StorageReference ImagesRef = storageRef.child("images/"+mAu.getCurrentUser().getUid()+".jpg");
ByteArrayOutputStream baos = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.JPEG, 20, baos);
byte[] data = baos.toByteArray();
final UploadTask uploadTask = ImagesRef.putBytes(data);
uploadTask.addOnFailureListener(new OnFailureListener() {
#Override
public void onFailure(#NonNull Exception exception) {
Log.i("whatTheFuck:",exception.toString());
}
}).addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
#RequiresApi(api = Build.VERSION_CODES.KITKAT)
#Override
public void onSuccess(final UploadTask.TaskSnapshot taskSnapshot) {
// taskSnapshot.getMetadata() contains file metadata such as size, content-type, and download URL.
Task<Uri> urlTask = uploadTask.continueWithTask(new Continuation<UploadTask.TaskSnapshot, Task<Uri>>() {
#Override
public Task<Uri> then(#NonNull Task<UploadTask.TaskSnapshot> task) {
if (!task.isSuccessful()) {
Log.i("problem", task.getException().toString());
}
return ImagesRef.getDownloadUrl();
}
}).addOnCompleteListener(new OnCompleteListener<Uri>() {
#Override
public void onComplete(#NonNull Task<Uri> task) {
if (task.isSuccessful()) {
Uri downloadUri = task.getResult();
DatabaseReference ref = FirebaseDatabase.getInstance().getReference().child("users").child(mAu.getCurrentUser().getUid());
Log.i("seeThisUri", downloadUri.toString());// This is the one you should store
ref.child("imageURL").setValue(downloadUri.toString());
} else {
Log.i("wentWrong","downloadUri failure");
}
}
});
}
});
}

If i understand correctly you can upload images to storage succesfully but you are having trouble when you want to get that image direct url.
Try this code:
StorageReference storageRef=FirebaseStorage.getInstance().getReference().child("images/"+ UUID.randomUUID().toString());
storageRef.putFile(filePath).addOnCompleteListener(new OnCompleteListener<UploadTask.TaskSnapshot>() {
#Override
public void onComplete(#NonNull Task<UploadTask.TaskSnapshot> task) {
if(task.isSuccessful()){
storageRef.getDownloadUrl().addOnSuccessListener(new OnSuccessListener<Uri>() {
#Override
public void onSuccess(Uri uri) {
String URL = uri.toString();
//This is your image url do whatever you want with it.
}
});
}
}
});
