there is edittext and button in edittext (phone number), button (registration) how to implement registration? Is there an API / server (how do we get a phone number to receive an activation code), or who has a ready code?

Main.java code

EditText editTextPhone; Button buttonRegister; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); editTextPhone = (EditText) findViewById(R.id.editTextPhone); this.editTextPhone.setText("996"); editTextPhone.setSelection(3); buttonRegister = (Button) findViewById(R.id.buttonRegister); buttonRegister.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View view) { Log.v("EditText", editTextPhone.getText().toString()); //Log.v("EditText value=", editTextPhone.getText().toString()); } }); } }

found this code here!
