Hello. I am developing a simple app with login and password, but there are always problems when trying to log in. It is worth saying that I am using Okhttp.
This is Java:
EditText txt_Email, txt_Pass;
TextView reg;
Button btn_Login;
String url = "";
String parametros = "";
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_login_screen);
txt_Email = (EditText) findViewById(R.id.email);
txt_Pass = (EditText) findViewById(R.id.password);
btn_Login = (Button) findViewById(R.id.button);
reg = (TextView) findViewById(R.id.textView2);
reg.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent abreCadastro = new Intent(LoginScreen.this, SplashScreen.class);
startActivity(abreCadastro);
}
});
/*btn_Login.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
}
});*/
}
public void ClickLogin(View view){
ConnectivityManager connMgr = (ConnectivityManager)getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo networkInfo = connMgr.getActiveNetworkInfo();
if (networkInfo != null && networkInfo.isConnected()) {
String email = txt_Email.getText().toString();
String senha = txt_Pass.getText().toString();
if(email.isEmpty() || senha.isEmpty()) {
Toast.makeText(getApplicationContext(), "Preencha todos os dados", Toast.LENGTH_SHORT).show();
}else {
url = "http://meudominio.host.com/login.php?email=" + email + "&senha=" + senha;
parametros = url;
new SolicitaDados().execute(url);
}
} else {
Toast.makeText(getApplicationContext(), "Falha de Conexão", Toast.LENGTH_SHORT).show();
}
}
private class SolicitaDados extends AsyncTask<String, Void, String> {
@Override
protected String doInBackground(String... urls) {
return Conector.postDados(urls[0], parametros);
}
// onPostExecute displays the results of the AsyncTask.
@Override
protected void onPostExecute(String resultado) {
reg.setText(resultado);
if(resultado.contains("login_ok")) {
Toast.makeText(getApplicationContext(), "Login Efetuado", Toast.LENGTH_SHORT).show();
}else{
Toast.makeText(getApplicationContext(), "Dados Incorretos", Toast.LENGTH_SHORT).show();
}
}
}
/*@Override
protected void onPause() {
super.onPause();
finish();
}*/
This is the XML of Activity:

</LinearLayout>
</RelativeLayout>
