Android application stops when using camera (onDestroy)

I have an android application which at a certain point the user requested a photographic evidence, before adding the services of google play services and firebase worked without problems .

The manifest is already configured in case it goes in the background keep the changes made.

<application

Method that I use to run or request the camera.

public void intentTakePhoto(int codeResult)
    {
        boolean result = Permission.checkPermissionCamera(ActivityMain.this);
        Log.e("intentTakePhoto: ", " = "+result);
        if (result)
        {
            if(contrato.getCount()>0)
            {
                imageName = "/DIRAPP/" + pref.getText() + "_" + pos.getSelectedItem().toString() + "_" + codeResult + ".jpg";
                file = new File(Environment.getExternalStorageDirectory() + imageName);
                Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);

                Uri Foto = FileProvider.getUriForFile(getApplicationContext(), getApplicationContext().getPackageName()+ ".provider", file);

                if (Build.VERSION.SDK_INT > 23)
                {
                    Log.e("intentTakePhoto: ", ">21");
                    intent.setFlags(Intent.FLAG_GRANT_WRITE_URI_PERMISSION);
                    intent.setFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
                    intent.putExtra(MediaStore.EXTRA_OUTPUT, Foto);
                }else
                {
                    Log.e("intentTakePhoto: ", "Normal");
                    intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(file));
                }
                SharedPreferences.Editor editor = mPrefs.edit();
                editor.putString("stock",stock.getText().toString());
                editor.commit();
                startActivityForResult(intent, codeResult);
            }else{
                mostrarAlerta("No hay datos.");
            }
        }else{
            mostrarAlerta("No tiene permisos para usar la camara");
        }
    }

After taking the photographic evidence, or when opening the camera the application restarts.
