When I was using my Android Studio to create a simple registration to my local database I met the problem that shows on the title, and here is my code:
public class registerInterface extends AppCompatActivity {
private EditText editTextUsername, editTextPassword, editTextEmail;
private Button buttonRegister, backToLogin;
private ProgressDialog progressDialog;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.registration_interface);
editTextUsername = findViewById(R.id.username);
editTextPassword = findViewById(R.id.password);
editTextEmail = findViewById(R.id.email);
buttonRegister = findViewById(R.id.register);
backToLogin = findViewById(R.id.go_back_login);
progressDialog = new ProgressDialog(this);
buttonRegister.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
registerUser();
}
});
}
public void registerUser(){
final String email = editTextEmail.getText().toString().trim();
final String password = editTextPassword.getText().toString().trim();
final String username = editTextUsername.getText().toString().trim();
progressDialog.setMessage("Registering...");
progressDialog.show();
StringRequest stringRequest = new StringRequest(Request.Method.POST, DataBaseConstants.URL_REGISTER, new Response.Listener<String>() {
@Override
public void onResponse(String response) {
progressDialog.dismiss();
try {
JSONObject jsonObject = new JSONObject(response);
Toast.makeText(getApplicationContext(), jsonObject.getString("message"), Toast.LENGTH_LONG).show();
} catch (JSONException e){
e.printStackTrace();
}
}
}, new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
progressDialog.hide();
Toast.makeText(getApplicationContext(), error.getMessage(), Toast.LENGTH_LONG).show();
}
}){
@Override
protected Map<String, String> getParams() throws AuthFailureError {
Map<String, String> params = new HashMap<>();
params.put("username", username);
params.put("email", email);
params.put("password", password);
return params;
}
};
RequestQueue requestQueue = Volley.newRequestQueue(this);
requestQueue.add(stringRequest);
}
}
I have already add these in my AndroidManifest.xml, but still does not work:
<uses-permission android:name="android.promission.INTERNET"/>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE"/>
I don't if it is the problem about the IP address, but I just cannot figure it out.
