Lifecycle Methods
onCreate(Bundle savedInstanceState)
Initializes Firebase references and loads user data based on role:
@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.my_account);
storageReference = FirebaseStorage.getInstance().getReference();
mDatabase = FirebaseDatabase.getInstance().getReference(Constants.DATABASE_UPLOADS);
auth = FirebaseAuth.getInstance();
SessionManager sm = new SessionManager(getApplicationContext());
HashMap<String, String> details = sm.getUserDetails();
final String id = details.get("id");
final String role = details.get("role");
if(role.equals("Manager")) {
// Load manager data
} else {
// Load salesperson data
}
}
The activity uses a ProgressDialog with a 1-second delay to ensure Firebase data is fully loaded before displaying to the user.
Data Loading
Loading Manager Data
Retrieves manager information from Firebase:
reference = FirebaseDatabase.getInstance().getReference("Manager");
final ProgressDialog dialog = ProgressDialog.show(
AccountManager.this,
"Loading...",
"Please wait...",
true
);
Handler handler = new Handler();
handler.postDelayed(new Runnable() {
public void run() {
reference.addListenerForSingleValueEvent(new ValueEventListener() {
@Override
public void onDataChange(@NonNull DataSnapshot dataSnapshot) {
for (DataSnapshot snapshot : dataSnapshot.getChildren()) {
sm1 = snapshot.getValue(SalesManager.class);
if(snapshot.getKey().equals(id)) {
currName = sm1.getName();
currPass = sm1.getPassword();
currOrg = sm1.getOrgName();
currMobile = sm1.getNumber();
currEmail = sm1.getEmail();
// Load profile image
ImageSetter.setImage(
getApplicationContext(),
imageView,
currEmail,
spinnerImage
);
break;
}
}
update_name.setText(currName);
update_org.setText(currOrg);
update_email.setText(currEmail);
update_mobile.setText(currMobile);
dialog.dismiss();
}
});
}
}, 1000); // 1000 milliseconds
Loading Salesperson Data
Retrieves salesperson information and associated manager’s organization:
reference = FirebaseDatabase.getInstance().getReference("Salesperson");
reference.addValueEventListener(new ValueEventListener() {
@Override
public void onDataChange(@NonNull DataSnapshot dataSnapshot) {
for (DataSnapshot snapshot : dataSnapshot.getChildren()) {
sp1 = snapshot.getValue(SalesPerson.class);
if (snapshot.getKey().equals(id)) {
currPass = sp1.getPassword();
currName = sp1.getName();
currMobile = sp1.getNumber();
currEmail = sp1.getEmailId();
final String currManager = sp1.getManagerName();
// Fetch manager's organization name
reference = FirebaseDatabase.getInstance().getReference("Manager");
reference.addListenerForSingleValueEvent(new ValueEventListener() {
@Override
public void onDataChange(@NonNull DataSnapshot dataSnapshot) {
for (DataSnapshot snapshot : dataSnapshot.getChildren()) {
sm2 = snapshot.getValue(SalesManager.class);
if (sm2.getName().equals(currManager)) {
currOrg = sm2.getOrgName();
break;
}
}
// Update UI
update_name.setText(currName);
update_org.setText(currOrg);
update_email.setText(currEmail);
update_mobile.setText(currMobile);
ImageSetter.setImage(
getApplicationContext(),
imageView,
currEmail,
spinnerImage
);
dialog.dismiss();
}
});
break;
}
}
}
});
Salespersons don’t have their own organization field. The activity fetches the organization name from their associated manager’s record.
Profile Picture Management
Image Selection
Opens the device’s image picker:
private void showFileChooser() {
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(
Intent.createChooser(intent, "Select Picture"),
PICK_IMAGE_REQUEST
);
}
imageChooser.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
showFileChooser();
}
});
Image Processing
Handles selected image with compression:
@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
);
// Compress image to 20% quality
ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.JPEG, 20, byteArrayOutputStream);
imageDataInByte = byteArrayOutputStream.toByteArray();
// Display in ImageView with circular crop
Glide.with(getApplicationContext())
.load(bitmap)
.apply(RequestOptions.circleCropTransform())
.into(imageView);
} catch (IOException e) {
e.printStackTrace();
}
}
}
Images are compressed to 20% JPEG quality to reduce storage costs and improve upload speed while maintaining acceptable visual quality for profile pictures.
Image Upload to Firebase Storage
Uploads the compressed image and stores the URL in Firebase Realtime Database:
private void uploadFile() {
if(filePath != null) {
final ProgressDialog progressDialog = new ProgressDialog(this);
progressDialog.setTitle("Uploading");
progressDialog.show();
final String fileName = Constants.STORAGE_PATH_UPLOADS +
System.currentTimeMillis() + "." +
getFileExtension(filePath);
final StorageReference sRef = storageReference.child(fileName);
sRef.putBytes(imageDataInByte)
.addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
@Override
public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
progressDialog.dismiss();
Toast.makeText(getApplicationContext(),
"File uploaded",
Toast.LENGTH_LONG).show();
Task<Uri> s = sRef.getDownloadUrl()
.addOnCompleteListener(new OnCompleteListener<Uri>() {
@Override
public void onComplete(@NonNull Task<Uri> task) {
downloadUrl = task.getResult().toString();
upload = new Upload(currEmail, downloadUrl);
// Store or update in database
mDatabase.addListenerForSingleValueEvent(
new ValueEventListener() {
@Override
public void onDataChange(
@NonNull DataSnapshot dataSnapshot) {
int flag = 0;
for(DataSnapshot snapshot :
dataSnapshot.getChildren()) {
if(snapshot.getValue(Upload.class)
.getEmail().equals(currEmail)) {
mDatabase.child(snapshot.getKey())
.setValue(upload);
flag = 1;
break;
}
}
if(flag != 1) {
String uploadId = mDatabase.push()
.getKey();
mDatabase.child(uploadId)
.setValue(upload);
}
}
});
}
});
}
})
.addOnFailureListener(new OnFailureListener() {
@Override
public void onFailure(@NonNull Exception e) {
progressDialog.dismiss();
Toast.makeText(getApplicationContext(),
"Upload failed!!",
Toast.LENGTH_LONG).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 + "%...");
}
});
} else {
Toast.makeText(getApplicationContext(),
"No image selected!!",
Toast.LENGTH_LONG).show();
}
}
imageUploader.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
uploadFile();
}
});
File Extension Helper
public String getFileExtension(Uri uri) {
ContentResolver cR = getContentResolver();
MimeTypeMap mime = MimeTypeMap.getSingleton();
return mime.getExtensionFromMimeType(cR.getType(uri));
}
The upload system checks if a profile picture already exists for the user’s email. If found, it updates the existing record; otherwise, it creates a new one.
Password Reset
Sends a password reset email using Firebase Authentication:
change_password.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
new FancyAlertDialog.Builder(AccountManager.this)
.setTitle("Warning!!!")
.setBackgroundColor(Color.parseColor("#00A144"))
.setMessage("Do you really want to change password ?")
.setNegativeBtnText("No")
.setPositiveBtnBackground(Color.parseColor("#FF4081"))
.setPositiveBtnText("Yes")
.setNegativeBtnBackground(Color.parseColor("#FFA9A7A8"))
.setAnimation(Animation.POP)
.isCancellable(true)
.setIcon(R.drawable.ic_error_outline_black_24dp, Icon.Visible)
.OnPositiveClicked(new FancyAlertDialogListener() {
@Override
public void OnClick() {
auth.sendPasswordResetEmail(update_email.getText().toString())
.addOnCompleteListener(new OnCompleteListener<Void>() {
@Override
public void onComplete(@NonNull Task<Void> task) {
if (task.isSuccessful()) {
Toast.makeText(
AccountManager.this,
"We have sent you instructions to reset your password!",
Toast.LENGTH_SHORT
).show();
} else {
Toast.makeText(
AccountManager.this,
"Failed to send reset email!",
Toast.LENGTH_SHORT
).show();
}
}
});
}
})
.build();
}
});
Password resets are handled through Firebase Authentication’s built-in email system, ensuring secure password recovery without storing passwords locally.
Logout Functionality
Clears session and returns to login screen:
logout.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
SessionManager sm = new SessionManager(getApplicationContext());
sm.logoutUser();
auth.signOut();
Intent intent = new Intent(AccountManager.this, MainActivity.class);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK | Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intent);
finish();
}
});
The logout process clears both the local session (via SessionManager) and the Firebase Authentication session, then clears the activity stack to prevent returning to authenticated screens via the back button.
