Next, we will answer this question in detail and provide solutions to help you better understand and solve this common Java development problem.

Question content

I am trying to display a confirmation screen once a fall is detected. If a fall is detected, I call "showconfirmation" with the following flow:

Method called when a fall is detected:

public void showconfirmation(context context, string data) {
        intent intent = new intent(context, caidaactivity.class);
        intent.addflags(intent.flag_activity_new_task);
        intent.putextra("data", data);
        startactivity(intent);
    }

Activities to display:

public class CaidaActivity extends AppCompatActivity {

    private String data;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        data = getIntent().getExtras().getString("data");
        actualizarTextos(R.string.caida_texto, R.string.caida_aceptar, R.string.caida_cancelar);
        playSonido();
        playVibracion();
        startContador();
    }
...

I tried the very basic print("here") debugging method and found that the method "oncreate" was never called. Does anyone know why?

Solution

Have you defined your activity in the manifest file? If so, then the error may be hidden in the fall check.
