title: Data is not uploading in Firebase database from Android
body: <p>I've followed a tutorial on youtube on inserting data into Firebase database. I've created Member class:</p>
  
  <pre><code>package com.example.bazadanych;
  
  public class Member {
      private String name;
      private String age;
      private String phoneNumber;
      private String height;
  
      public Member() {
      }
  
      public String getName() {
          return name;
      }
  
      public String getAge() {
          return age;
      }
  
      public String getPhoneNumber() {
          return phoneNumber;
      }
  
      public String getHeight() {
          return height;
      }
  
      public void setName(String name) {
          this.name = name;
      }
  
      public void setAge(String age) {
          this.age = age;
      }
  
      public void setPhoneNumber(String phoneNumber) {
          this.phoneNumber = phoneNumber;
      }
  
      public void setHeight(String height) {
          this.height = height;
      }
  }
  </code></pre>
  
  <p>And I created code in MainActivity:</p>
  
  <pre><code>public class MainActivity extends AppCompatActivity {
      EditText editName, editPhone, editAge, editHeight;
      Button btnSave;
      DatabaseReference ref;
      Member member;
  
      @Override
      protected void onCreate(Bundle savedInstanceState) {
          super.onCreate(savedInstanceState);
          setContentView(R.layout.activity_main);
  
          editName = (EditText) findViewById(R.id.editName);
          editAge = (EditText) findViewById(R.id.editAge);
          editPhone = (EditText) findViewById(R.id.editPhone);
          editHeight = (EditText) findViewById(R.id.editHeight);
          btnSave = (Button) findViewById(R.id.buttonSave);
          ref = FirebaseDatabase.getInstance().getReference().child("Member");
  
          member = new Member();
  
          btnSave.setOnClickListener(new View.OnClickListener() {
              @Override
              public void onClick(View v) {
                  String name = editName.getText().toString().trim();
                  String age = editAge.getText().toString().trim();
                  String height = editHeight.getText().toString().trim();
                  String phone = editPhone.getText().toString().trim();
  
                  member.setName(name);
                  member.setAge(age);
                  member.setHeight(height);
                  member.setPhoneNumber(phone);
  
                  ref.push().setValue(member);
  
              }
          });
      }
  </code></pre>
  
  <p>The problem is I can't see data on website. I enabled writing and reading by passing true value on the website. I've connected my app to Firebase and add database to my project. I don't know where the problem is. Anybody can help me?</p>
