Good evening friends puej the truth I do not know what is wrong I'm drowning in a small problem because I tell you that an attempt to open another activity does not work for me not that it is wrong but the other intents if: here the code:

@Override
public void onClick(View v) {


    if(v.getId() == R.id.btnAgregarSoporte){
        Intent abrirAgregarSoporteActivity = new Intent(this,AgregarSoporteActivity.class);
        startActivity(abrirAgregarSoporteActivity);
    }
    if(v.getId() == R.id.btnPublicarAnuncio){
        Intent abrirAgregarUbicacionYProdInm = new Intent(getApplicationContext(),AgregarUbicacionYproductoInmueble.class);
        startActivity(abrirAgregarUbicacionYProdInm);
    }

    if(v.getId() == R.id.btnVerAnuncios){
            Intent AbrirAnuncios = new Intent(this,AnunciosActivity.class);
        Toast.makeText(getApplicationContext(),"Pero llega",Toast.LENGTH_LONG).show();  // inclusive llega hasta aqui cuando quito la linea de abajo
        startActivity(AbrirAnuncios); // cuando quito esta linea funciona pero obviamente no abre la otra activity si no que muestra el mensaje de la anterior linea
    }




}

As you see all the intents here work except the frame with comment the truth is not what happens I have set everything and nothing can help me, because the application is closed by pressing that button see ads. thanks.

In case you need something else, I can modify the question and add more code or whatever you need.

As the previous comment says it is incorrect to use this within the onclick method, so the solution would be:

@Override
public void onClick(View v) {
    if(v.getId() == R.id.btnAgregarSoporte){
startActivity(new Intent(getApplicationContext(),AgregarSoporteActivity.class));
    }
    if(v.getId() == R.id.btnPublicarAnuncio){
startActivity(new Intent(getApplicationContext(),AgregarUbicacionYproductoInmueble.class));
    }

    if(v.getId() == R.id.btnVerAnuncios){
    startActivity(new Intent(getApplicationContext(),AnunciosActivity.class));
            Toast.makeText(getApplicationContext(),"Pero llega",Toast.LENGTH_LONG).show();  // inclusive llega hasta aqui cuando quito la linea de abajo
// cuando quito esta linea funciona pero obviamente no abre la otra activity si no que muestra el mensaje de la anterior linea
        }
    }

Remove several lines that you had and simplify it to one, I hope it works for you. Good luck and greetings.

It is incorrect to use this as context within the method:

@Override
public void onClick(View v) {
 ...
 ...
 ...
}

You must use as a context the call to the getApplicationContext() method:

Intent AbrirAnuncios = new Intent(getApplicationContext(),AnunciosActivity.class);

Or also refer to the Activity, assuming that your Activity is called MainActivity :

Intent AbrirAnuncios = new Intent(MainActivity.this,AnunciosActivity.class);

Sometimes we add Activity to our projects but they are not automatically registered in AndroidManifest.xml , add the activity within your AndroidManifest.xml to be registered in your application.

 <application
     ...
      ...
      <activity android:name=".AnunciosActivity"/>
  </application>
