Strange behavior in DB - Too many records Form within Form [duplicate]

score 4 · Accepted Answer

Your code that builds the intent to start the dialer is wrong. It should look like this:

    Intent it= new Intent(Intent.ACTION_DIAL);
    it.setData(Uri.parse("tel:34621026"));
    if (intent.resolveActivity(getPackageManager()) != null) {
        iniciarTelefone(it);
    }

Another thing, why do you call the finish () after starting the intent. This will terminate the application. Is it to do this?
