}

================edit potongan kode di EditorActivity.java==================
public void onItemSelected(AdapterView adapterView, View view, int i, long l) {
String selection = (String) adapterView.getItemAtPosition(i);
if (!TextUtils.isEmpty(selection)){
if (selection.equals("Male")) {
nGender = PetContract.PetEntry.GENDER_MALE;
} else if (selection.equals("Female")) {
nGender = PetContract.PetEntry.GENDER_FEMALE;
} else {
nGender = PetContract.PetEntry.GENDER_UNKNOWN;
}
}
}

selanjutnya===============================
terjadi redudansi, maka hilangkan Pet.Contract menjadi:
public void onItemSelected(AdapterView adapterView, View view, int i, long l) {
String selection = (String) adapterView.getItemAtPosition(i);
if (!TextUtils.isEmpty(selection)){
if (selection.equals("Male")) {
nGender = PetEntry.GENDER_MALE;
} else if (selection.equals("Female")) {
nGender = PetEntry.GENDER_FEMALE;
} else {
nGender = PetEntry.GENDER_UNKNOWN;
}
}
}

bagian import juga di edit:
