there are no errors. but I can stop it by uninstalling it using ADB
Edit: it works fine after I edit it manually edit in firebase and then open that activity from the main activity.

Might be not related answer but whenever you are using any firebase or firestore
event try to pass "this("activity context")" as the first parameter it will manage the
activity life cycle and will remove you listener when your app will be in background.

App crashes whenever I log out, authentication with firebase

i'm creating a sing in up and whenever i log in then log out i crash, I get this error:

I don't get why it's happening,it was working fine before

Before using fAuth.getCurrentUser().getUid() check if there is a user currently signed in
FirebaseUser user=FirebaseAuth.getInstance().getCurrentUser();
if(user!=null){
StorageReference profileRef= storageReference.child("users/"+user.getUid()+"/profile.jpg");
profileRef.getDownloadUrl().addOnSuccessListener(new OnSuccessListener<Uri>(){
#Override
public void onSuccess(Uri uri){
Picasso.get().load(uri).into(profileImage);
}
});
}
That should solve the problem, but still you will have to handle a user not signed in

You can try this:
private void uploadData() {
loadingBar.setTitle("Registering Retailer....");
loadingBar.setMessage("Please Wait While We Are Creating Retailer Database");
loadingBar.setCanceledOnTouchOutside(false);
loadingBar.show();
handleUpload(bitmap);
}
private void initializeUrl(Uri uri) {
profile_image_url = uri.toString();
//Initialize Firebase Database;
mDatabase = FirebaseDatabase.getInstance().getReference();
createUserDatabase(name, mobile, pass, spinner_port_place, profile_image_url);
}
And use addListenerForSingleValueEvent instead of addValueEventListener. More useful.
Upload the profile picture first, then save the user to the database.
This is not the case with your code. You save the user to the database and pass to the other screen until the profile picture is uploaded.

The password is invalid or the user does not have a password

I'm trying to create a login and register system in Android Studio using Firebase. Registration works pretty well, user is created in Firebase successfully. But whenever I try to login it gives me this error "The password is invalid or the user does not have a password" even though the password I entered is the same I registered with. I think the problem might be with my code because user can login perfectly when I create account for given user on Firebase Console directly. What might cause this problem?
I provided my login and my register activity code:
Login activity

progressDialog = new ProgressDialog(this);
mAuth = FirebaseAuth.getInstance();
signupLink.setOnClickListener(new View.OnClickListener() {
#Override

{
startActivity(new Intent(MainActivity.this, RegistrationActivity.class));
}
});
forgetPassword.setOnClickListener(new View.OnClickListener() {
#Override

{
startActivity(new Intent(MainActivity.this, ResetActivity.class));
}
});
loginBtn.setOnClickListener(new View.OnClickListener() {
#Override

{

}
});
}
private void loginDetails()
{
String email = emailLoginEditText.getText().toString().trim();
String password = passwordLoginEditText.getText().toString();
if(TextUtils.isEmpty(email))
{
emailLoginEditText.setError("Email can't be empty...");
return;
}
if(TextUtils.isEmpty(password))

else
{
progressDialog.setTitle("Login");
progressDialog.setMessage("Please wait while we are connecting you");

progressDialog.show();
mAuth.signInWithEmailAndPassword(email, password).addOnCompleteListener(new OnCompleteListener<AuthResult>() {

The problem that is telling to you is that you are doing wrong the reference, you are trying to get something inside Firebase Database that is not there
This line is telling you that the child("Users").child(KeyUser); does not exist in your current DB structure
To fix this you should see your databse structure and then redo your reference.
if you post a photo of your Firebase DB i will be glad to refactor your code to your needs.
also here you are getting wrong your USER_KEY
keyUser = getIntent().getStringExtra("USER_KEY");
To fix this a short way would be doing this
keyUser = getIntent().getExtras().getString("USER_KEY");
you are geting an intent from where? if you are trying to get a putExtra from another Activity, you are doing it wrong, post where you are seting the extra ("USER_KEY");
Intent.getStringExtra() and Intent.getExtras() returns null if there are no extras, so you need to check for that before trying to call getString()
one quick example to check for extras first would be this
String keyUser;
Bundle extras = getIntent().getExtras();
if(extras == null) {
Log.e("keyUser is null","");
} else {
keyUser= extras.getString("USER_KEY");
}
happy coding

Java is a programming language and computing platform first released by Sun Microsystems in 1995.

Activity opening itself [closed] - java

Might be not related answer but whenever you are using any firebase or firestore event try to pass "this("activity context")" as the first parameter it will manage the activity life cycle and will remove you listener when your app will be in background.
