Using StartActivityForResult and onResultReceive i'm getting an error. is there something wrong?

The activity that gives the result:

public void onClick(View arg0) {
    if (Login.length()==0 || Senha.length() == 0) {
        Toast.makeText(getLogin.this, "Por favor preencha login e senha!", Toast.LENGTH_LONG);
        return;
}
Bundle gGuy = new Bundle();
gGuy.putStringArray("Login", new String[] {Login.getText().toString(), Senha.getText().toString()});
//gGuy.putString("Login", Login.getText().toString());
//gGuy.putString("Senha", Senha.getText().toString());
Intent i = new Intent();
i.putExtra("bGuy", gGuy);
setResult(RESULT_OK, i);
finish();

}

And the result receiver:

protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (requestCode == 555) {
        if (resultCode == RESULT_OK) {
            Bundle bGuy = data.getExtras();
            Info = bGuy.getStringArray("Login");
            doMe = new Syncro();
            doMe.execute();
        }
        else {
            doLog.doWarning("Erro ao obter login da intent result!");
            return;
        }
    }
}

Logcat error:

SOLVED: Changed 'putExtra' to 'putExtras' Result: 开发者_StackOverflow社区 i.putExtras(gGuy);

You have a problem at this line in your code :

 Info = bGuy.getStringArray("Login");

var has no name.

But your problem might come from the way you use your bundle in the finishing activity. Try

if( login.getText() == null || Senha.getText() == null )
{
  //Toast and return
}//if

Intent i = new Intent();
Bundle gGuy = i.getExtras();

gGuy.putStringArray("Login", new String[] {Login.getText().toString(), Senha.getText().toString()});
//gGuy.putString("Login", Login.getText().toString());
//gGuy.putString("Senha", Senha.getText().toString());
setResult(RESULT_OK, i);
finish();

Then you can get your array back in OnActivityResult (please add @Override annotation) in the way you already did it.

And please, read this about naming conventions in java.

Info = bGuy.getStringArray("Login");

Тhis is the faulty line. Instantiate it correctly.

Something like:

String[] Info = bGuy.getStringArray("Login");
