How to retrieve image from firestore in a clickable span widget? - java

I have successfully uploaded the media in the firebase but i'm unable to retrieve it. apparently it shows that the media_problem is pointing to a null object. below is my code.
This is my code to retrieve:
this.view.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
Toast.makeText(Dash_agri.this.getApplicationContext(), "TOO FAST! TRY AGAIN", Toast.LENGTH_LONG);
try {
Dash_agri.this.firestore.collection("problems").get().addOnCompleteListener(new OnCompleteListener<QuerySnapshot>() {
public void onComplete( Task<QuerySnapshot> task) {
if (task.isSuccessful()) {
Dash_agri.this.records.clear();
Iterator it = ((QuerySnapshot) task.getResult()).iterator();
while (it.hasNext()) {
QueryDocumentSnapshot document = (QueryDocumentSnapshot) it.next();
Dash_agri.this.single_ID = document.getId();
Dash_agri.this.single_name = (String) document.get("NAME_problems");
Dash_agri.this.single_phone = (String) document.get("PHONE_problems");
Dash_agri.this.single_description = (String) document.get("DESCRIPTION_problems");
Dash_agri.this.single_URL = (String) document.get("MEDIA_problems");
String view_media = "Touch to view media";
new SpannableString(view_media).setSpan(new ClickableSpan() {
public void onClick(View widget) {
Toast.makeText(Dash_agri.this.getApplicationContext(), "inside", Toast.LENGTH_LONG).show();
}
}, 0, 9, 33);
Dash_agri.this.record_id.add(Dash_agri.this.single_ID);
ArrayList<String> arrayList = Dash_agri.this.records;
StringBuilder sb = new StringBuilder();
sb.append("QUERY#");
sb.append(Dash_agri.this.single_ID);
sb.append(" by ");
sb.append(Dash_agri.this.single_name);
sb.append("\n");
sb.append(Dash_agri.this.single_description);
sb.append("\n\n");
sb.append(view_media);
arrayList.add(sb.toString());
}
}
}
});
} catch (Exception e) {
Toast.makeText(Dash_agri.this.getApplicationContext(), e.getMessage(), Toast.LENGTH_LONG);
}
Dash_agri.this.listView.setAdapter(new ArrayAdapter<>(Dash_agri.this.getApplicationContext(), R.layout.simple_list_item_1, Dash_agri.this.records));
}
});
This is my code to upload:
public class Upload extends AppCompatActivity {

}
});
}
}
});
} catch (Exception e) {

public void upload_file_also(Uri fileUri) {
StorageReference storageReference2 = this.storageReference;

sb.append("ProbID-");
sb.append(this.TIME_ID);
final StorageReference sr = storageReference2.child(String.valueOf(sb.toString()));
sr.putFile(fileUri).addOnSuccessListener((OnSuccessListener<TaskSnapshot>) new OnSuccessListener<TaskSnapshot>() {
public void onSuccess(TaskSnapshot taskSnapshot) {
sr.getDownloadUrl().addOnSuccessListener(new OnSuccessListener<Uri>() {
public void onSuccess(Uri uri) {
Upload.this.MEDIA_url = uri.toString();
Upload.this.progressBar.setVisibility(View.VISIBLE);
Upload.this.upld.setText("TAP AGAIN TO UPLOAD MEDIA");
}
});
}
});
}
}
I'm unable to find why this isn't working. Please put a light on where this is going wrong.

Android firestore when users change the image, NullPointerException occurs

I'm making setup_profile activity. Users can change information.

Show the image stored in Firebase storage in Imageview from Firebase Database

I'm trying to show the image which has been sucessfully uploaded in firebase storage and whose unique id is also updated in Firebase Database under "pics" in my Imageview but I did tried multiple time but am unable to show the image or retrive images .
Below is my Firebase Database Structure.

In UploadBook class change this
if(filePath != null) {
mStorageRef.child(bookid[0]).putFile(filePath).addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
#Override
public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
Task<Uri> downloadUrl = taskSnapshot.getMetadata().getReference().getDownloadUrl();
Toast.makeText(UploadBook.this, "Upload successful", Toast.LENGTH_SHORT).show();
dbreference.child("books").child(item).child(bookid[0]).child("pics").setValue(downloadUrl.toString());
}
})
.addOnFailureListener(new OnFailureListener() {
#Override
public void onFailure(#NonNull Exception e) {
}
});
}
To This-
final StorageReference ref = mStorageRef.child(bookid[0]);
UploadTask uploadTask = ref.putFile(file);
Task<Uri> urlTask = uploadTask.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 ref.getDownloadUrl();
}
}).addOnCompleteListener(new OnCompleteListener<Uri>() {
#Override
public void onComplete(#NonNull Task<Uri> task) {
if (task.isSuccessful()) {
Uri downloadUri = task.getResult();
dbreference.child("books").child(item).child(bookid[0]).child("pics").setValue(downloadUri.toString());

} catch (IOException e) {

}
You can then upload to firebase with the this code:
final UploadTask uploadTask = bytepath.putBytes(thumb_byte_data);
uploadTask.addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
#Override
public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {

// Continue with the task to get the download URL
return filepath.getDownloadUrl();
}
}).addOnCompleteListener(new OnCompleteListener<Uri>() {
#Override
public void onComplete(#NonNull Task<Uri> task) {
if (task.isSuccessful()) {
thumb_download_url = task.getResult().toString();
}
}
});
}
}).addOnFailureListener(new OnFailureListener() {
#Override
public void onFailure(#NonNull Exception e) {
}
});

You can create bitmap with captured image as below:
Bitmap bitmap = Bitmap.createScaledBitmap(yourimageuri, width, height, true);// the uri you got from onactivityresults
You can also view this thirdparty lib to compress your image Click Here

//declear local variable first

Uri imageUri;
//button action to call Image picker method
companyImage.setOnClickListener(new View.OnClickListener() {

This unique id SiQEIDaQJfUBqZBBt1eo is generated when you are adding the user as a Map or when you are using a call to document() method without passing an argument.
In order to solve this, there are two ways. One would be to create a model class (UserModel), then create an object of that class and in the end get the uid of the user once it authenticated and add the object to the database like this:
String Name = textInputEditTextName.getText().toString().trim();
String Email = textInputEditTextEmail.getText().toString().trim();
String Password = textInputEditTextPassword.getText().toString().trim();
String Phone_Number = textInputEditTextPhone.getText().toString().trim();
String ConfirmPassword = textInputEditTextConfirmPassword.getText().toString().trim();
UserModel userModel = new UserModel(Name, Email, Password, Phone_Number, ConfirmPassword);
String uid = FirebaseAuth.getInstance().getCurrentUser().getUid();
FirebaseFirestore rootRef = FirebaseFirestore.getInstance();
CollectionReference usersRef = rootRef.collection("users");
usersRef.document(uid).set(userModel);
See, I have passed the uid as argument to the document() method.
The second approach would be to pass no argument to the document() method but to store that key into a variable like this:
String key = usersRef.document().getKey();
usersRef.document(key).set(userModel);
Edit:
There also another method, which I recommend you use it. Instead of using this line of code:
mFirebaseFirestore.collection("users")
.add(user)
.addOnSuccessListener(/* ... */)
Use the following line of code:
mFirebaseFirestore.collection("users")
.document(uid)
.set(user)
.addOnSuccessListener(/* ... */)
Remove the old data, add fresh one and your problem will be solved.
