Отображение фрагмента после съемки

Question

Я работаю над приложением Android с навигационной панелью с левой стороны. Когда я нажимаю на кнопку, я могу отобразить свой фрагмент, а на другой кнопке запускаю камеру.

Я хочу, чтобы сделать снимок и отобразить его в моем фрагменте, но у меня есть следующее исключение Java Runtime:

java.lang.RuntimeException: Failure delivering result ResultInfo{who=null, request=1, result=-1, data=Intent { dat=file:///storage/emulated/0/photo.jpg }} to activity {com.example.fred.myApplication/com.example.fred.myApplication.MainActivity}: 
     java.lang.IllegalStateException: Can not perform this action after onSaveInstanceState 

Мой код:

public class MainActivity extends AppCompatActivity 
     implements NavigationView.OnNavigationItemSelectedListener, FormFragment.OnFormFragmentInteractionListener { 
private File mFichier; 
private ImageView mImageView ; 

// On déclare une constante dans la classe FirstClass 
public final static int REQUEST_IMAGE_CAPTURE = 1 ; 
public final static String EXTRA_PICS_URI = "com.example.fred.myapplication.PICS_URI"; 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 
    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar); 
    setSupportActionBar(toolbar); 

    DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout); 
    ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(
      this, drawer, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close); 
    drawer.setDrawerListener(toggle); 
    toggle.syncState(); 

    mImageView = (ImageView) findViewById(R.id.imageView3); 

    NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view); 
    navigationView.setNavigationItemSelectedListener(this); 
} 

@Override 
public void onBackPressed() { 
    DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout); 
    if (drawer.isDrawerOpen(GravityCompat.START)) { 
     drawer.closeDrawer(GravityCompat.START); 
    } else { 
     super.onBackPressed(); 
    } 
} 

@Override

    if (resultCode != Activity.RESULT_CANCELED) {

Answer 1

Есть два варианта.

---

Вариант 1.

fragmentManager.commitAllowingStateLoss(); 

или

fragmentManager.commitNowAllowingStateLoss(); 

вместо fragmentManager.commit();

---

Вариант 2.

new Handler().postDelayed(
    new Runnable() { 
     //... 
     fragmentManager.commitAllowingStateLoss();// or fragmentManager.commit(); 
     //... 
    }, 50);
