First of all please have a look at rules defined for Firebase Realtime Database. If you're not using Firebase Auth, You can Update rules like this.
Goto Realtime Database then change tab to Rules and update rules.
{
"rules": {
".read": true,
".write": true
}
}
Then you can write data.
private void InsertStudentData(){
String name=stname.getText().toString();
String email=stemail.getText().toString();
String phone=stphone.getText().toString();
String password=stpassword.getText().toString();
Students students=new Students(name,email,phone,password);
studentref.setValue(students).addOnSuccessListener(new OnSuccessListener<Void>() {
@Override
public void onSuccess(Void aVoid) {
Toast.makeText(StudentregisterActivity.this,"Register Successfully",Toast.LENGTH_SHORT).show();
}
})
.addOnFailureListener(new OnFailureListener() {
@Override
public void onFailure(@NonNull Exception e) {
Toast.makeText(StudentregisterActivity.this,"Register failed",Toast.LENGTH_SHORT).show();
}
});
}

Make sure following things
- Internet permission in Manifest.
- Set Firebase Realtime database Rules to Public/Authenticate user for private rules.
- Internet Availability on testing device to push data into database.
To set Internet Permission
<uses-permission android:name="android.permission.INTERNET" />
To set rules to public
- Goto Firebase console
- Realtime database rules
- Paste this code in rules
**
{
“rules”: {
“.read”: true,
“.write”: true
}
}
**
At the end try uploading data using the code below
DatabaseReference rootRef = FirebaseDatabase.getInstance().getReference();
DatabaseReference tasksRef = rootRef.child("Students").push();
Students students=new Students(name,email,phone,password);
tasksRef.setValue(student);
