Не переходит в новое активити

Мое первое приложение на андроид, не судите строго...

spinnerFastInfo = findViewById(R.id.spinner_FastInfo);
        String[] spinnerList_FastInfo = getResources().getStringArray(R.array.tires_FastInfo);
        ArrayAdapter<String> spinnerAdapter = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_item, spinnerList_FastInfo);
        spinnerAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
        spinnerFastInfo.setAdapter(spinnerAdapter);

        spinnerFastInfo.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
            @Override
            public void onItemSelected(AdapterView<?> adapterView, View view, int i, long l) {
                Toast.makeText(getApplicationContext(),
                        "Запись - " + adapterView.getAdapter().getItem(i).toString() + "\nПозиция - " + i,
                        Toast.LENGTH_SHORT).show();

             switch (i) {
                    case 1:

                      Intent intent = new Intent(getApplicationContext(),ShowPageActivity.class);
                        //intent.putExtra("tireChosen", 0);
                       // intent.putExtra("chosenInfo",i);
                  startActivity(intent);
                        break;
                    default:
                        break;
                }
            }

на этапе перехода в новое активити просто выкидывает из приложения...
